Title: Amplifier circuit
Inventor: MATSUOKA AKIO
IPC: H03F1/38
Filed: 1989-05-30
Abstract: PURPOSE:To obtain a stable amplifier circuit with a prescribed high amplification factor by using a positive feedback circuit so as to feed back an output of a differential amplifier circuit and changing the current of a constant current circuit so as to promote an output change in the differential amplifier circuit. CONSTITUTION:A noninverting output outputted from a collector of a transistor(TR) 7 of a differential amplifier circuit 1 is inputted to the base of a TR 10 of a positive feedback circuit 2 and a noninverting output is outputted from the positive feedback circuit 2 and given to bases of TRs 15, 16 of the constant current circuit 3. For example, the base voltage of the TRs 15, 16 is increased to increase the current of the constant current circuit 3. Since the output current of the constant current circuit 3 is changed to promote the output change of the differential amplifier circuit 1, the amplitude of the output signal extracted from the emitter of a TR 13 is increased and the circuit acts like an amplifier circuit whose amplification factor is constant and high.

Title: Variable capacity type compressor with swing plate
Inventor: KUROSAWA JUETSU
IPC: F04B27/14
Filed: 1986-06-12
Abstract: PURPOSE:To provide a pressure adjusting valve with less power loss by furnishing a moving element at the farther end of pressure response bellows, which is connected with a valve body to shut a communication line between a crank chamber and the suction side when the suction pressure has dropped, and by allowing said moving element to move the valve body in the valve closing direction as the discharge pressure is sinking. CONSTITUTION:When discharge pressure Pd and suction pressure Ps exceed specified values, the discharge pressure Pd is applied to the pressure receiving part 41 of No.2 moving element 37 to move it apart from a No.1 moving element 26 against the action of No.2 spring 39, while the suction pressure Ps is applied to bellows 24 to move the valve body 25 apart from the opening in a communication line 2b leading from the crank chamber to the suction side. When the two pressures are below the specified values, a No.1 spring 27 elongates with drop of both pressures to move the valve body 25 in the valve closing direction, and said No.2 moving element 37 pressure No.1 moving element 26 with the resilience of No.2 spring 39 to move the valve body 25 further in the valve closing direction. Thereby eventual drop of the discharge pressure does not cause drop of the pressure in the crank chamber to allow accomplishment of a pressure adjusting valve with less power loss.

Abstract: PURPOSE:To lift liquid to a higher spot with a small quantity of compressed air by decreasing a diameter of an air lift pipe from a lower part suction end toward an upper part discharge end to increase a bubble occupation ratio at the discharge end more than the suction end. CONSTITUTION:In an air lift pipe 1, a pipe inner diameter of the pipe 1 is decreased in stages from a compressed air blow-out port 2 provided in the vicinity of lower part suction end 3 of this pipe 1 toward an upper part discharge end 4. Accordingly, on the way of the pipe 1, the diameter of an intermediate part pipe 1b is decreased in a stage than that of a lower part pipe 1a. Further, the diameter of an upper part pipe 1c is decreased, different diameter flanges 9a, 9b are arranged at an appropriate interval, and respective pipes 1a, 1b, 1c are connected to each other to form a deformed shape pipe. With this constitution, since a bubble occupation ratio at respective positions of the air lift pipe 1 is increased from the lower part suction end 3 toward the upper part discharge end 4, liquid can be lifted to a higher spot with a small quantity of compressed air.

Abstract: PURPOSE:To perform smooth and even descaling by projecting abrasives mixed with high pressure water by a specific ratio from multi-layer arranged flat spray nozzles at a specific angle and then picking a stainless steel plate. CONSTITUTION:Abrasives discharged from abrasive nozzles 2 are projected with an impact force corresponding to a high pressure water flow mixed with a water volume being about 1.0-1.7 times as large as the volume of the abrasives onto a surface of a steel plate 4. The projection is such that flat spray nozzles 1 are set in a multi-layer arrangement, the projection angle is 60-90 deg., preferably 70-80 deg. with about a 100kg/cm<2> pressure, and projection regions 5 lap partly to each other.

Title: Memory protecting device
Inventor: NARIMATSU HIROSHI
IPC: G06F21/79
Filed: 1989-05-31
Abstract: PURPOSE:To rapidly execute writing processing by temporarily storing an access address in an exclusive storage means and reading out the contents of a protect memory during the temporary storage of the access address. CONSTITUTION:The protect memory 3 detects an illegal access from the upper several bits of an address bus, an access type and an execution level. When a CPU 1 reads out data written in a data latch but not written in the memory 2, a coincidence detecting circuit 9 detects the status and allows the CPU 1 to read out not the data of the memory 2 but the data of the data latch. When a signal BERR is in the high level, a control circuit 39 controls the data latch so that data writing from the data latch to the memory 2 is not executed to prevent data from being destroyed due to illegal writing. Consequently, waiting time for reading out data from the protect memory 3 can be eliminated and rapid processing can be attained.
