Title: Piston cavity of swirl-chamber diesel engine
Inventor: TANAKA TOSHIAKI
IPC: F02F3/26
Filed: 1982-02-09
Abstract: PURPOSE:To reduce the amount of the uncombusted gas in exhaust by setting the dispersion part of a clover-leaf-shaped piston cavity, opposed to intake and exhaust valves, and forming an air taking-in groove in the stalk part of the dispersion part, and thus increasing the capacity ratio of a swirl-chamber while maintaining a compression ratio. CONSTITUTION:The dispersion part 27B of a piston cavity 27 is set at a position permitting the use of said part 27B as a valve recess, namely opposed to intake and exhaust valves 27C and 27D. Air taking-in grooves 28 are formed on the both sides of the stalk 27A of the cavity 27, and used as the tapered grooves towards the bottom surface of the stalk part 27A. The formation positions of the grooves 28 are shifted alternately to right and left. Therefore, the swirl- chamber capacity ratio can be set large enough, while maintaining a compression ratio, and the air in the part 29 enclosed by the broken line in a main chamber 6 is introduced into the stalk part 27A through the air taking-in grooves 28 by the gas flow which gushes out into the stalk part 27A from a jet port 5 in high speed. Thus, the air utilization rate in the main chamber 6 can be increased effectively.

Title: Detecting device for specific gravity of electrolytic solution of accumulator or capacity thereof
Inventor: TANAKA AKIFUMI
IPC: G01R31/36
Filed: 1981-02-10
Abstract: PURPOSE:To detect the specific gravity of the electrolytic solution or the capacity of the accumulator found from the specific gravity by substracting from the reference voltage the voltage of the accumulator or the charged voltage thereof while it is charged with a very small  current and by magnifying in display a change thus found. CONSTITUTION:When electrodes 1 and 2 are inserted into the electrolytic solution 9 of a prescribed single cell 8 and are charged by a DC power source 3, an inter-electrode voltage rises  and becomes stable. Assuming that the inter-electrode voltage at the time when the value of  the specific gravity of the electrolytic solution 9 is a normal value of the specific gravity be  the voltage of a reference voltage device 5, the both-end voltage of a resistor 6 turns to be OV at the time of the normal value of the specific gravity. When the specific gravity of the  electrolytic solution of the accumulator to be measured lowers through discharge, the voltage  between the electrodes 1 and 2 changes and a voltage proportional to the amount of lowering  of the value of the specific gravity appears at both ends of the resistor 6. By detecting said  voltage by a milli voltmeter 7 and by graduating the scale of the milli voltmeter 7 with the  specific value based on a conversion of 1mV=0.001, the lowered value of the specific gravity  can be read out directly therefrom. In addition, it is also possible the relation between the  specific gravity and the capacity known by actual measurement is indicated by the capacity.

Filed: 1980-02-20
Abstract: PURPOSE:To operate an aperture remotely by driving aperture blades through the reciprocal vibration of an electromagnetic driver, by supplying the driver with a pulse signal corresponding to a preset aperture value. CONSTITUTION:An aperture value is preset in preset counter 22 by aperture setter 21. When switch 4 is turned on with the release button, counter 22 starts operation with a signal from operation timing circuit 24 and generates an output of ''1'' and a pulse input is supplied from oscillator 23 for subtraction counting operation. Then, when the substraction value becomes zero, ''0'' is outputted. Therefore, counter 22 outputs ''1'' only for the time that corresponds to the preset value and during the period, AND gate 25 is opened to drive electromagnetic driver 9. Next, blade feed pawl 10 is made to reciprocate as many times as the number of pulses and ratchet wheel 6a is driven to rotate aperture operation ring 6, stopping down aperture blades 8. Thus, the aperture is operated remotely.
