Filed: 1991-02-28
Abstract: PURPOSE:To reliably take out sheet bodies one by one from a sheet body containing part without damaging the forward end of the sheet body by a method wherein by bending a topmost sheet body, a lower sheet body next to the topmost sheet body is separated, a press force is then released and the forward end thereof is moved forward through the restoration force of the sheet body, and the forward end is protruded from a paper sheet containing part. CONSTITUTION:A roller 23 is forced into pressure contact with a sheet body P1 A first press means 24 forces a plate into pressure contact with the sheet body P1, and a second press means 25 has a pin separated away from the sheet body P1. In which case, when the roller 23 is rotated, the topmost sheet body P1 is moved leftward and bent. Thus, the topmost sheet body P1 is separated from a lower sheet body P2 next to the topmost paper sheet. The plate of the first press means 24 is separated away from the sheet body P1. In which case, the sheet body P1 is brought into a flat state through its own resilient force and protruded from a container 14, and delivered through rotation of the roller 23. The forward end of the sheet body P1 is moved to rollers 45 and 46. A second press means 25 is brought into pressure contact with the sheet body P2 so as to prevent movement of the sheet body P2.

Title: Drum-driving device for mixer truck
Inventor: TAKAO SHIYOUSUKE
IPC: B60P3/16
Filed: 1983-04-04
Abstract: PURPOSE:To obtain stable running of a mixer truck by providing a servo-motor by detecting a low-speed position of a speed change gear by a position detector to bring a variable capacity type liquid-pressure pump to a neutral position for stopping a drum automatically when the mixer truck is started or driven on a steep slope. CONSTITUTION:When a speed change lever 4a is thrown in the first speed at the time of starting or driving on a steep slope, a limit switch 19 is on to move a switch valve 15 to a position A. Thereby, the pressure liquid from an auxiliary pump 13 to a servo-motor 14 is drained to make the servo-motor 14 free from the work of the pressure liquid. Consequently, a piston device 16 of the servo- motor is automatically returned to a neutral position by the work of springs 16a and 16b without reference to the operational position of an operation lever 18. Then, the liquid-pressure pump 6 is operated at the neutral position, and the pressure liquid is not supplied to a liquid-pressure motor 7 to stop a drum. When a speed-change lever 4a is switched over to a high-speed position, the drum can be operated for normal rotation. This construction permits to prevent an operator from operating a mixer truck erroneously.

Abstract: PURPOSE: To perform a high-accuracy slicing to ensure the conversion into the binary signal by using a small number of the PROM device plus the shift register to the image supplied in multiple value.  
     CONSTITUTION: The peak value of the information equivalent to one scan is detected for input multi-value video information (A). (Each figure within frame 25 shows the multi-input level.) And noise deletion level is decided to the peak value, and then the decided level is supplied to counter 4 and register 6. Then division 7 is carried out using the memorized 6 value and the value of counter 4 to obtain the average value of the effective level equivalent to one scan. The average value is then sent to registers 8W10. PROM11 memorizes slice level α corresponding to each average value supplied from registers 8W10 and then sends the value of the level to comparator 13. While information (A) is delayed 2 and 12 to be sent to comparator 13 in the same phase as the scan level of the image opposing to level α. Thus, the levels over α are sliced to obtain binary coded image 26. (B).

Title: Refrigerant bypass valve
Inventor: IRINO YASUMI
IPC: F25B41/04
Filed: 1990-03-09
Abstract: PURPOSE:To improve the effect of prevention of an overheat of a compressor and to increase the reliability of an operation by a construction wherein a valve disk of a passage making an inlet part on the high pressure side communicate with an outlet part on the low pressure side is joined to a diaphragm receiving the atmospheric pressure on the outside and the action of a pressure on the low pressure side on the inside and the valve disk is made to open when the pressure on the low pressure side lowers. CONSTITUTION:At the time of a steady operation of a refrigeration cycle, the quantity of a refrigerant supplied to an evaporator 5 is sufficient and therefore the pressure Ps of the refrigerant on the low pressure side is higher than the atmospheric pressure Pa. A diaphragm 16 turns to make an action on a valve disk 14 in the direction of closing, through a valve steam 19. While the valve disk 14 is actuated in the direction of opening by a spring 15, the pressure Pd of the refrigerant on the high pressure side acts thereon in the direction of closing, and consequently the valve disk 14 is held in a closed state. A liquid refrigerant on the high pressure side is not led out onto the low pressure side. When a compressor overheats a little and the quantity of refrigerant circulating through the refrigeration cycle lessens, the pressure Ps on the low pressure side on the downstream side of the evaporator 5 lowers. In a refrigerant bypass valve 7, the valve disk 14 is opened by a pulling force of the spring 15 when the pressure Ps on the low pressure side lowers and approaches the atmospheric pressure Pa.

IPC: H01L21/302
Filed: 1996-03-15
Abstract: PURPOSE: To increase the throughput, without needing a wafer retainer by installing a passage to vent a coolant gas between a wafer and wafer susceptor and passage cover opened only while power-off. CONSTITUTION: A coolant gas feed passage 24 is formed at a wafer susceptor 6 and coolant feed pipe is connected to this passage. A coolant gas is fed to the back side of a wafer 8 sucked and held on a dielectric film 7 through a flow rate controller disposed in the coolant gas feed pipe. One or more coolant gas vent holes 33 communicated with a coolant gas groove 30 are formed at the susceptor 6 and cover 31 is pressed to outlets thereof by an actuator 32 to seal them. In the event of power interruption, the actuator 32 goes back to open the cover 31 and the coolant gas 34 in the groove 30 is sucked into a vacuum treating chamber to quickly equalize the pressure on the back side of the wafer 8 and this chamber. This avoids shifting or dropping the wafer and reduces scattering of dust, thereby elevating the throughput.
