I'm going to change subject of my hobby this year, because I have done well on automobiles as long as 12 years and on the camera equipment modifications those are almost over soon. The direction to be aimed at is "Airfoil" based on aerodynamics and hydrodynamics and related "Vortex generator". I want to reproduce the phenomenon on Radio Controlled Model Airplane and to obtain various datum to be analyzed. These are the very desire that I had been stored in my heart from my youth.
Though I'm working now as a active duty and weekdays are fully occupied by my business, I'll do that in very near future after the alternation of generation would be attained by my son. Spectacular advances must have done by the researcher in the scientific field also in Radio communication technology. I'm looking forward to going into the field deeper as one of my hobby for a geriatric person. The model airplane would be designed as a shoulder wing, motor set in carburetor upright position and motor capacity with 25 cube/inches.

Rough tie-rod adjustment on the left side at Kobe Kinki Department of Motor Vehicles destroyed the centricity of the steering gear box arm resulting tire hitting phenomena in right tire house of VW 1302 Super Beetle while a measuring for the other day's inspection test. This is mainly caused by the irregularity of steering link operating range because of the steering gear box control arm angular difference. In addition the movement limit stoppers on idler case construction were not adjusted well from the beginning. As a conclusion, tie-rod adjustment should be performed with the condition of fixing steering gear box control arm centricity, As I mentioned before, precisely established frontal wheel alignment should be the key to a following rear wheel alignment, total toe and it's direction, thrust angle that is the most important geometric alignment for stable driving. 1 mm toe-in would be applied under minus 20 minutes camber inclination.
About the steering box part for right steering position design, no further parts supply in the world is done, so the death of this part means the end of right steering 1302 and 1303 Super Beetles. I have already obtained this gear box as a replacement parts, used but no symptom of wear. Steering movement stopper construction is formed on gear box case for 1303 parts, instead on drag link for 1302.

A lead car battery condition is observed by measuring the voltage between opened terminals, though the datum obtained by opened voltage measuring is abstract compared with the method of doing the specified gravity of electrolyte. Just measuring voltage method is simply easier than the latter one. The battery shown here was self-discharged until loosing the electric capacity that could not activate starter motor of Hybrid TOYOTA Crown, 65D23L. For 9 hours gradual charging at 16,5V/2A(switching power supply) has recovered to show 12,20V between opened terminals, almost 50% capacitance has saved and more charging is required to fulfill the original capacitance. Basically, the battery once ruined would not recover the original performance, but it would play a part of emergency use. As a common sense, a lead battery should be charged at 10% higher voltage with 1/10 current of the battery capacitance, I make it a rule to at much higher voltage with lower current taking longer time as gradual charging method, according to my experience, this method has never caused any problem like destructive curvature of electrodes. Before all, electrode liquid level should be at the same decided amount by adding pure water promptly.
For a long time of period I believed that the play of a lead car battery is just activation of starter electric motor and give an initial combustion spark, then once started, the battery has almost nothing to do with the motor performance, because the power supply is mainly by the alternator rotating together with motor performance. But, actually the fact isn't true, because some ruined battery requires charging energy from the alternator connected with the motor by way of belt and the motor power would be consumed by activated alternator rotation. This is why a new and healthy enough car lead battery provides light and comfortable run. As the charging energy in an alternator is supplied by motor combustion energy, so a fully charged requiring no charging is one of an indispensable factor to establish comfortable and astringent run.

A friendly neighbor made it possible to have a good circumstance as a holiday home for me giving a suitable parking place and it was an unexpected and unhoped for joy, because the place is broad and wide enough space to maintain my automobiles including wheel alignment and axle constructive geometries. Consequently, I'm busy for transferring garages and all the instrument settled on former villa place. Long kept villa in the mountain side would be sold away because of no future hopeful advantages. Now, I'm capable to service for my automobiles in closed condition without any external interferences like animals, cats, dogs, weasels nor mice. Wide and broad space makes me released from any stresses. In addition, the concrete floor finishing is relatively flat, so a little efforts would be required to establish ground level that is an indispensable requirement for precise wheel alignment and axle construction geometry measurement and adjustment. Accumulation of fundamental and steady efforts like this would be of a great help to bear sweet fruit for me.

The modification of Leitz TELE-Elmar 135/4 old M lens setting on Canon EOS digital imaging format has successfully completed last late at night. Because some complicated conjunctive parts was utilized, Minolta MC ROKKOR 135/3,5 helicoid, it took time for me far longer than the method just putting the EOS bayonet flange nails on Minolta lenses as I did much previously. As for my surprise, the potential in image resolution is eye-opening and phenomenal so much, just realized I the fact that TELE-Elmar is used by some professional purpose for datum recording of Nara Remains(Cultural property), provably this exceptional capability in Resolution had made him determine to choose TELE-Elmar 40 years ago as a main recording device. Extraordinary potential of this historical lens would be survived on Digital Imaging element, Complementary Metal-Oxide Semiconductor in Canon 7D.
But, remember that my modification way is not destructive one but reversible, so I can returned back this modified TELE-Elmar as it had been in original condition, Leica M bayonet lens whenever desired.
How does this lens play as a reproduction tool, stopping the time, cutting out a specific three dimensional space and reproducing some smell of the air space (feeling of the air) without any dramatization nor exaggeration? The lens designing concept of putting an emphasis on the capability of resolution rather than contrast reflecting well to the untrained eye is nothing but the characteristic requirement for my favorite tool on earth.
Any inconvenience for ordinary use is not discerned at present, but very slight hitting phenomena on Minolta flange inside surface between straight helicoid movement guide piece axially is observed now, so a little adjustment there by grinding would eliminate this sense of discomfort thoroughly. Any bug should be removed however slight it may be, if an ultimate performance is required as a extraordinary special performance tool.
