Title: Swash plate type variable capacity compressor
Inventor: KUROKAWA YOSHIO
IPC: F04B27/08
Filed: 1989-06-22
Abstract: PURPOSE:To sufficiently feed lubricating oil even in a small capacity operation state by installing a control valve which is opened and closed by the differential pressure between the operation pressure as control pressure or discharge pressure and the pressure in a swash plate chamber, into a passage formed between an oil separating chamber and the swash plate chamber. CONSTITUTION:A swash plate type variable capacity compressor for car air conditioner, varies the installation position and inclination angle for the shaft 13 of a swash plate 26 in correspondence with the control pressure supplied into a control pressure chamber 41, and varies each operation stroke of the pistons 311 and 312 and varies the discharge capacity. In this case, if the discharge capacity is large, the sliding mechanism part in a swash plate chamber 24 is lubricated properly. When the discharge capacity is small, each quantity of coolant and oil which is returned becomes less, and in this state, an oil return valve 45 is opened by the differential pressure between the control pressure or discharge pressure and the pressure in the swash plate chamber 24, and the oil 431 stored in an oil separating chamber 43 is sent into the swash plate chamber 24, and the sliding part is lubricated by the stirring of the swash plate 26. Therefore, the durability and reliability of the compressor can be improved.

Title: Automatic straight device controller for mobile working machine
Inventor: NAKAMURA HACHIRO
IPC: A01B69/00
Filed: 1992-05-27
Abstract: PURPOSE:To maintain the straight drive performance of a mobile working machine by controlling the traveling direction of the working machine based on the computing result obtained from the moving deviation angle detected by a gyro. CONSTITUTION:When a mobile working machine is set in a steady traveling state where the working machine travels at a fixed speed after a turning motion, an operator releases his hand from a steering gear to start the automatic steering control. Thus, the value of a gyro 13 so far integrated is reset and the value obtained when the automatic steering control started is read into a CPU 16 as a reference deviation angle theta01. Meanwhile, the moving deviation angle thetaX of the traveling working machine is obtained when the angular velocity detected by the gyro 13 is integrated by an integration circuit C1 in terms of time. The difference DELTAtheta=(thetaX-theta01) is calculated and therefore the lateral deviation value X of the work machine is obtained at a fixed traveling speed. A CPU 16 controls a steering output device 17 so that the value X is set at 0.

Title: Testing method for wide band fm detecting circuit
Inventor: SAITOU KAZUO
IPC: G01R31/316
Filed: 1981-10-07
Abstract: PURPOSE:To measure an FM detection limit point invariably with high precision by detecting the FM detection limit point through electronic circuitry even if the output voltage at the FM detection limit point is different between wide band FM detecting circuits, and thus eliminating the possibility that the difference in output voltage causes the efficiency of measurement to decrease. CONSTITUTION:A sine-wave sweep generator 7 is swept up to a frequency presumed to be much higher than a detection limit frequency, and a storage command signal 10 is sent to a DC voltage storage device 9 to store and hold the output voltage of an integrated circuit 1 to be tested. Then, a circuit switch 13 is put in operation to supply a sweep start command signal 8 to a sine-wave sweep generator 7 again, thereby increasing the frequency. A DC voltage detector 11 is applied with the stored and held output voltage as an input signal; when the voltage difference between those two input voltages is within a small difference range between a positive and a negative potential, an output signal is generated as a sweep stop command signal 12 and then transmitted  to a sweep stop signal terminal 15 through the circuit switch 13, so that the sweep of  a measurement input signal frequency stops at the FM detection limit frequency. At  this time, the current input signal frequency is measured by a frequency counter 3 to  find the FM detection limit frequency of the integrated circuit 1 to be tested.
