Title: Brake system for training vehicle
Inventor: OGURA OSAMU
IPC: B60T11/10
Filed: 1981-12-23
Abstract: PURPOSE:To boost brake force even upon actuation of auxiliary brake, by operating a booster driving piston through a spool valve with the use of hydraulic pressure from a piston actuated by a main brake pedal or from an auxiliary brake master cylinder. CONSTITUTION:The interior of a housing of a booster operating device 3 is separated into three chambers, that is, a first chamber 12, a second chamber 13 and a spool valve chamber 14. A first piston 15 coupled to a main brake pedal 1 is inserted in the first chamber 12, and a second piston 16 for operating a booster 6 is inserted into the second chamber 13. Both chambers 12, 13 are connected together through the spool valve chamber 14, and a spool valve 17 for controlling the communication therebetween is disposed in the spool valve chamber 14. An auxiliary brake master cylinder 23 is connected through a pipe line 24 to the inlet port 21 of the chamber 14 at the side opposite to the communication port 20 of the chamber 14 communicated with the chamber 12. The spool valve 17 is formed with grooved spools 26, 27 at both sides of a center spool 23, and fitted with seal members 18, 29 at both ends of the spool valve 17. These seal members controls the communication between the chamber 14 and the communication port 20 or the inlet port 21 under open and close control.

Title: Material-testing machine
Inventor: KITAOKA TAKASHI
IPC: G01N3/02
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To mount a load cell with a simple seat surface structure and to achieve an accurate measurement and test by joining the load cell and either of a fixing or traveling member for installing the load cell through a coating film. SOLUTION: For example, in the case of tensile testing, a test piece 12 is gripped between upper and lower chucks 6U and 6D, and screw rods 2R and 2L driven, thus moving up a cross head 3. A pull load applied to the test piece 12 at this time is detected by the load-sensitive part of a load cell 7 via the upper chuck 6U and a universal joint. In this case, the load weight of the test piece 12 acts on the load cell 7 and the cross head 3. However, since a Teflon film TF is interposed between the seat surface of the load cell 7 in the cross head 3 and the lower surface of the load cell 7 corresponding to the seat surface, the surfaces can be displaced. Therefore, the lower surface part of the load cell 7 is smoothly deformed corresponding to an operated load, thus preventing a load detection error caused by the polling or the like from being generated.

Title: Semiconductor storage device
Inventor: MIZUKAMI MASAO
IPC: G11C11/413
Filed: 1989-08-14
Abstract: PURPOSE:To save power consumption by forming a control timing signal for activating an internal storage circuit by an internal timing generating circuit based upon a control signal specifying an operation mode. CONSTITUTION:The internal timing generating circuit TG forms the control timing signal for activating the practical internal storage circuit M-ARY based upon the control signal specifying the operation mode. Since the internal RAM circuit M-ARY is driven only for a fixed time based upon clocks, data line charge discharging AC current or DC current flowing into a sense amplifier SA or the like can be quickly interrupted. Consequently, power consumption can be saved and a memory disabled from writing/reading within a fixed time can be decided as a defect memory.
