Title: Load sensing device for variable displacement pump
Inventor: MATSUMOTO SATORU
IPC: F04B49/08
Filed: 1994-06-08
Abstract: PURPOSE:To provide a load sensing device for a variable displacement pump to perform stable automatic control of a delivery flow rate of a pump. CONSTITUTION:An oil amount in the control chamber 12a of the delivery flow rate control means 12 of a variable displacement pump 10 is introduced and increased through a delivery line by a load sensing valve 40 and a pressure compensating valve 24 operated through the a differential pressure force between the front and the rear of a variable throttle 16 on a delivery line 14 and the resilient force of a spring 18. Meanwhile, by discharging and reducing an oil amount of the control chamber 12a to a tank line 28, a differential pressure between the front and the rear of a variable throttle 16 is held at a constant value through the decrease and the increase of a pump delivery flow rate. Thus, the control chamber 12a and the delivery line 14 are intercommunicated and/or disconnected by means of the load sensing valve 40. A line 42 bypassing directly to the tank line 28 is connected to the control chamber 12a and normally-opening fixed throttle 44 is arranged on the line.

IPC: G01R31/28
Filed: 1990-05-16
Abstract: PURPOSE:To make it possible to test an internal circuit with the signals having the different patterns by providing an intermediate-potential detecting means for detecting the intermediate potential between two logic levels, a test-mode setting FF and a test-mode selecting means. CONSTITUTION:Data which are inputted into an input terminal A are inputted into a register 51. The data which are shifted in response to an input clock are outputted to a register 52. The data are shifted in registers 53 - 54 in similar manner. The respective output data are outputted to ANDs 61 - 64 of a test- mode selecting means 6. The data outputted from the register 54 at the final stage are also outputted to an FF 4. In the FF 4, the data outputted from the register 54 are sent out when the logic level of the signal outputted from an inverter 7 with the clock that is outputted from the an AND 3 is 0. The data are outputted to the ANDs 61 - 64. When the input data are changed, a plurality of the different test-mode setting signals, e.g. (0, 1, 0 and 0), are outputted. The test data having the different modes are generated by the test signals and used as the signal for testing inner logics.

Title: Dual port memory for video
Inventor: NAKADA YOSHIHIRO
IPC: G06F12/04
Filed: 1993-05-28
Abstract: PURPOSE:To simplify an external circuit by providing a prediction means counting the number of data for valid display in a serial port memory and outputting a prediction signal predicting that the number of display data becomes zero. CONSTITUTION:A part of display data in RAM 11 is transferred to the serial port memory 14 by a RAM control signal 12 through an internal data bus 13. At that time, the number of data for valid display in the serial port memory 14 is written into a counter 16. Display data of the serial port memory 14 is sequentially read out by a serial port memory control signal 15. The counter 16 counts down the number of data for valid display at every reading, inputs the number of counting in a comparator 17, and the comparator 17 outputs a BTR signal when the number of counting becomes less than the number of counting, which corresponds to the time that is previously set. The external circuit monitors the BTR signal and starts the transfer of new data.

Abstract: PURPOSE:To flatten the unevenness of the joining surfaces by the plastic deformation by moving the cleaned joining surfaces of objects to be joined relatively in parallel to the joining surfaces while the joining surfaces are brought into contact with each other. CONSTITUTION:The objects 2A and 2B to be joined are installed on jigs 4A and 4B and a joining chamber 1 is exhausted to an ultra-high vacuum and the surfaces 201A and 201B are cleaned by a cleaning device.
