Title: Open type refrigerant compressor
Inventor: FUJIO KATSUHARU
IPC: F04C29/02
Filed: 1983-06-13
Abstract: PURPOSE:To lighten the requested pressure reducing capacity of a pressure reducing ring and reduce the abrasion of sliding surface by a method wherein the compressor is provided with a bypass path, communicating with a suction refrigerant gas path from a space in a packing device, a preliminary pressure reducing path at the upstream side of an oil supplying path and the pressure reducing ring, at the downstream side of the oil supplying path and engaged with a driving shaft. CONSTITUTION:The compressor is provided with the packing device 10 for securing the air- tightness of refrigerant in the main body of the compressor and refrigerating machine oil, the oil supplying path 21 for supplying the oil from an oil reservoir 16 at the delivery side into the space 9 in the packing device, the bypass path 12 communicating with the suction refrigerant gas path 4 from said space 9, the preliminary pressure reducing path 13 at the upstream side of the oil supplying path 21 and the pressure reducing ring 17 engaged with the driving shaft 7 at the downstream side of the oil supplying path 21. According to such constitution, a pressure in the oil supplying path 21 from the preliminary pressure reducing path 13 to the pressure reducing ring 17 becomes an intermediate pressure between the pressure (delivery side) of the oil reservoir 16 and the suction refrigerant path 4 (suction side), therefore, the requested pressure reducing capacity of the pressure reducing ring 17 is lightened to the pressure difference between the intermediate pressure and suction pressure. Accordingly, power loss of the driving shaft 7 due to pressure reducing as well as the abrasion of reduced pressure sliding surface may be reduced and the durability of the pressure reducing ring may be improved remarkably.

Abstract: PURPOSE: To shorten the warming-up time and perform good fixing treatment by providing a heating source provided with a heat radiation surface encircling nearly the half circumference of a pressure-contact roller in proximity to the pressure- contact roller.  
     CONSTITUTION: The heating roller 15 of a fixing device 14 is heated at the warming-up operation of an electrophotographic copier; at the same time, the electric  power is supplied to the heating  conductive layer 31 of a heating source 29 provided in proximity to a pressure-contact roller 21 and provided with a heat radiation surface encircling nearly the half circle of the roller 21. Thereby, the entire circumference of nearly the half circumference of the roller 21 spaced from the roller 15 is radiation-heated and the peripheral temperature of the roller 21 is raised rapidly. Hence, the warming-up time of the fixing device shortens and good fixing treatment is accomplished by the roller 21 turning in contact with the roller 15 by  spacing from the heating source 29 which is cut off of electric power supply upon ending of the uniform warming-up and the roller 15.

Title: Circuit for preventing reverse rotation of ignition means of internal combustion engine
Inventor: HASHIMOTO HIDEYUKI
IPC: F02P3/08
Filed: 1979-08-22
Abstract: PURPOSE:To prevent reverse rotation effectively, by keeping a transistor in conduction before it reaches the peak rise time of voltage from the time when a self-shortcircuiting regulator is set into actuation, and thereby increasing the conduction width of the transistor. CONSTITUTION:Voltage of a charge coil 1 is impressed to the base of a transistor 11 via a diode 19 and a resistance 20. Here, since the transistor 11 can be energized also by the plus voltage of charge coil 1, the conduction width of transistor 11 is increased toward the opposite side of an ignition signal at the time of normal rotation, so that operation is carried out normally in this state. At the time of reverse rotation, however, the conduction time of transistor 11 is increased since it is energized by the charged voltage and an advancing ignition signal can be also shortcircuited. Therefore, it is enabled to cause misfiring without fail at the time of reverse rotation within an operable range of a pulser.

IPC: G03G15/00
Filed: 1981-07-07
Abstract: PURPOSE:To make operation easier and quicker by permitting the use of an original feeder in interruption mode and providing a means of inhibiting an automatic original feed mode at that time. CONSTITUTION:When an interruption switch INTB is depressed during copying, a control part CRT interrupts copying in accordance with the signal from the switch INTB, and sets an interruption mode after storing said copying mode. At the same time, a flip-flop (FF) F3 is set, an FF F4 is reset, and an inverter I4 and an AND gate A4 go off. Here, the operator raises an original feeder 2 to prohibit its use, sets the original for interruption copying in the exposure position of the body 1 of the copying machine after setting copying conditions and depresses a copying start switch PS, then the control part CTR controls the body 1 so as to perform interruption copying. If the operator depresses the switch INTB again and turns it off after this, the part CTR releases the interruption mode and resumes the original copying mode.

Abstract: PURPOSE:To stabilize an inverter output frequency by changing a control output to an inverter at a delay time, when a variation is + or -1 bit, and changing said output immediately, when said variation amounts to + or -2 bits and over. CONSTITUTION:An analog output signal of a frequency setter 5 set and operated according to a desired frequency is converted into a digital signal by an A/D converter 6 and this digital signal is inputted with a given period to a variation identifying means 71 of a frequency control circuit 7.

Abstract: PURPOSE:To perform steady and efficient lapping of a sheet, by exerting brake force on the sheet passing a shear line by means of a linear motor located above the shear line and exerting brake force on the dropping sheet again for deceleration thereof by means of a linear motor situated below the shear line. CONSTITUTION:Sheets S, cut by a shear, are moved forward by a conveyor 3 on the carrying-out side of the shear, and when the forward end thereof is detected by a detector 12, an electromagnet 11 and a linear motor 9 are excited by means of the detecting signal to take over the sheet S sucked to the electromagnet 11, by the linear motor 9. After the sheet S, whereon the brake force applied by the linear motor 9 is exerted, is decelerated to the extent that the subsequent sheet is prevented from colliding with this sheet, the front part of the linear motor 9 is de-magnetized. When a linear motor 8 and an electromagnet 4a, assembled in a piling conveyor 4, simultaneously, are excited, the sheet drops onto the conveyor 4. In which case, the sheet S and the other sheet S are partially overlapped with each other, the frictional resistance produced as a result of the sheet making contact with the conveyor 4, and the brake force generated from the linear motor 8, are exerted thereon, and after the speed of sheet is reduced to the speed of the conveyor 4, it is piled on a piler lift 6.
