Title: Hydraulic pump with relief valve
Inventor: TAKITA SHINICHI
IPC: F04C14/24
Filed: 1990-01-30
Abstract: PURPOSE:To prevent the buildup of discharge pressure over the specified value even with the increase of the escape quantity by forming a throttle part in an escape passage, as well as forming a pressure lead-in passage for communicating the throttle part with a back pressure chamber so as to energize a valve body to slide into a communicating direction by the acting force based on the pressure generated according to an operating fluid passing through the throttle part. CONSTITUTION:A part inside an escape passage is throttled to form a throttle part 42. A pressure lead-in passage 44 for communicating the throttle part 42 with a storage hole 32 is bored to lead pressure generated according to an operating fluid passing through the throttle part 42 into a back pressure chamber 46. When the operating fluid passing through the escape passage 29 is large, the lowering degree of the pressure at the throttle part 42 becomes large, and this pressure acts upon the back pressure chamber 46 through the pressure lead-in passage 44, so that a valve body 30 is energized to slide into the communicating direction. Accordingly, even if the discharge of the operating fluid is large and the energizing force of a spring 38 is increased according to the spring constant, discharge pressure does not becomes higher than the specified value because of the pressure led into the back pressure chamber 46 through the pressure lead-in passage 44 in addition to the force of the operating fluid acting upon the valve body 30 through the communicating hole 24.

Title: Liquid crystal display device
Inventor: KITAJIMA MASAAKI
IPC: G09G3/36
Filed: 1994-02-16
Abstract: PURPOSE:To reduce power consumption while securing a fixed display at the time of stand-by. CONSTITUTION:A voltage control part 6 generates plural gradation displaying voltages. A signal driving circuit 1 generates a signal voltage with an amplitude according to gradation specified by the image data inputted through an interface circuit 7 by using the gradation displaying voltage generated by the voltage control part 6 to apply the generated voltage to a liquid crystal matrix panel 2. When the stand-by is instructed through the interface circuit 7, the voltage control part 6 reduces the value of the generated gradation displaying voltage. Thus, the amplitude of the signal voltage applied to the liquid crystal matrix panel 2 at the time of standby is reduced, and power consumption is reduced, and the display is secured though the quality of its display is deteriorated.

Abstract: PURPOSE:To facilitate the replacement job of the version number by performing the comparison between the version number of a program storage medium and the version number of a nonvolatile storage medium and writing automatically the data necessary for execution of a program into the novolatile storage medium when no coincidence is obtained between both version numbers. CONSTITUTION:In a normal working state, the version number stored in a version number storage area 3b of a RAM 3a is read out. Then the data on the RAM 3a are rewritten so as to secure the correspondence between a version No. V101, for example, of the RAM 3a and a vesion No. V103. Then the version number of a version No storage area 3b is rewritten into No. V103. Furthermore the data on the RAM 3a are rewritten so as to secure the correspondence between a version No. V102 of the RAM 3a and the No. V103. Then the version number of the area 3b is rewritten into the No. V103. Thus the data on the RAM 3a are rewritten into the data corresponding to a program of the No. V103. Thus the control processing is started to a copying action. In such a constitution, the replacement jobs are faciliated for version numbers.
