Title: Solenoid-operated proportional flow control valve with pressure compensating part
Inventor: INOUE KAZUO
IPC: F16K31/383
Filed: 1984-03-19
Abstract: PURPOSE:To perform complete pressure compensation, by setting the intermediate pressure decompressed at a pressure compensating part down to pilot pressure, and feeding this pilot pressure to a pressure receiving chamber of a flow control spool, while connecting the pressure receiving chamber to a load port. CONSTITUTION:The intermediate pressure P1 decompressed at a pressure compensating part X is set down to pilot pressure. And, this pilot pressure is fed to each of pressure receiving chambers 17 and 18 of a flow control spool 10, while these pressure receiving chambers 17 and 18 are interconnected to each of load ports 11 and 12. With this constitution, even if main flow and pilot flow both are made so as to be taken out of the same pressure oil source, such flow as corresponding to the opening of an opening part of the flow control spool 10 regardless of load pressure is feedable, that is to say, controllable to the flow that corresponds to a supplied current to solenoids 27 and 28 regardless of the load pressure. Therefore, in cooperation with pressure compensation at the pressure compensation part X, complete pressure compensation is performable.

Title: Exposure factor information generating circuit having temperature compensating characteristic
Inventor: OOTSUBO YOSHIAKI
IPC: H03F1/30
Filed: 1979-05-01
Abstract: PURPOSE: To prevent the effect of the temperature difference of the camera and speed light by transmitting the information of the positive temperature characteristic which an exposure factor information setting circuit outputs to the speed light by way of an amplifier circuit of negative temperature coefficients.  
     CONSTITUTION: The exposure factor information voltage at the terminal T 1  of film sensitivity, aperture, etc. set by way of a potentiometer 3 is beforehand made to the positive temperature characteristic allowing for temperature characteristic compensation of the exposure control circuit of the camera by a constant current source 4. This set voltage is regulated to the specified voltage according to temperature by a control resistance 2, by which the base of the PUP silicon transistor Q 1  which depends upon reverse saturated current and forms an amplfier circuit of negative temperature coefficients is controlled, thus the emitter voltage of the transistor Q 1  applied to the speed light becomes the exposure factor information voltage removed of temperature dependency. Hence, even when the speed light or the like of a temperature differing from that of the camera as it has been put in a pocket or the like in an extremly cold place is used, the effect of the temperature difference between the camera and speed light is prevented.

Title: Sorter fitted with stapler
Inventor: UMEDA ARATA
IPC: B65H39/11
Filed: 1989-03-07
Abstract: PURPOSE:To prevent operation for replenishing a stable needle from being interrupting during a job by detecting such a state that the residual amount of the staple needle in a stapler has been made equal to the number of a pin of a sorter or has reached only previously decided number or more than the number of the pin with a residual needle amount detecting means and indicating the state. CONSTITUTION:When a motor 116 is turned ON, a stapler pushes and bends the staples 119 in a cartridge 117. The staples 119 are joined in a band shape by a thin tape and accommodated in the cartridge 117. Further when the final part of the staple is passed through a near-end sensor 118, a near-end signal is output. Furthermore at a point of time when this signal is output, the residual amount of a needle is made more than the number of a pin of a sorter. There fore, actuation of the stapling is uninterrupted. For example, the sensor is ar ranged to the position of the staple needle of the same number as the number of the pin from the tip or to the position of the staple needle of only previously decided number or more than the number of the pin. The sensor detects such a state that the final part of the staple needle has passed and thereby it is indicated that all of the staple needle is consumed and supplement is necessary.
