Title: Method for painting inferior material
Inventor: OOTA SHIYOUZOU
IPC: B05D7/24
Filed: 1985-03-12
Abstract: PURPOSE:To apply an excellent corrosion-proof film to the surface of an inferior material, by applying an under coat composition, which has a characteristic reacting with the moisture contained in the rust composition on the surface of a steel plate and secured to said plate, to the surface of the steel plate, to which rust inhibiting pretreatment is applied, and coating a corrosion-proof top coat paint thereon. CONSTITUTION:An under coat composition containing a moisture curable isocyanate terminated type addition polymer is applied to the surface of a steel plate to which pretreatment by the washing of an oil component or a power tool is applied. By this method, the solvent in the composition dilutes and disperses a minute amount of the adhered oil component to be penetrated into the residual rust on the surface of the steel plate along with a polyurethane resin. The resin is solidified while chemically reacted with the OH group of moisture constituting the molecule of rust and the evaporation of the solvent is together generated to strongly secure rust in a state including a minute amount of the adhered oil component in said resin. Therefore, if an epoxy or tar epoxy top coat paint is applied to this prepared surface, high grade corrosion-proof painting is enabled.

Title: Automatic exposure controller
Inventor: YASHIMA HIROYUKI
IPC: E05F7/00
Filed: 1983-03-22
Abstract: PURPOSE:To prevent over-exposure during short-distance photography by outputting an exposure stop signal when the exposure value by reflected light is made larger than a reference value from an output means. CONSTITUTION:A CPU19 calculates the ratio A of a voltage signal corresponding to the electric power of a light sources and a voltage signal corresponding to the reflected light and compares the calculated ratio with a distance decision value alpha; when A>alpha, a decision on short distance is made and data of exposure level BX corrected ratio beta is outputted. An integral signal from an integrator 11 is inputted to a comparator 24 through a signal line 16. Therefore, the light emission of a strobe bulb 26 is stopped at the time T3 when the integral signal attains to a reference value BXbeta. The exposure is deficient with the current light emission time T0-T3, but there is a delay time T3-T4, so the actual light emission time is T0-T4 and the proper quantity of exposure corresponding to a set value B is obtained.

And, with excitation of an exciting coil 3a, a contact 3b is selected to an up-terminal 3c and feeds a driving signal which drives a light body to situate an upright position. With this constitution, the light body shifts from a housing position to the upright position and comes to a stop. Likewise, the light body is lighted by this operation. At this time, the control transistor 6 is as well turned to ON, with which a driving transistor 5a of the timer 5 is also turned to ON whereby a condenser C1 comes into a state of being charged as well. On the other hand, the timer 7 keeps an off-state.
