Title: Active boosting circuit for mos type integrated circuit
Inventor: FURUYAMA TOORU
IPC: G11C11/409
Filed: 1982-01-28
Abstract: PURPOSE:To set bit line potential to high potential, by connecting one of the drain or the source of a depression type TR to one joint of an MOSIC, connecting the other to the first terminal of a capacitor, to raise the potential of the second terminal of the capacitor. CONSTITUTION:One of the drain or the source of a depression type MOS transistor 26 is connected to the first terminal of a capacitor 27, and the other is connected to a bit line 30. By gate voltage phiD of the TR26, the potential of the source and a joint 29 of the first terminal of the capacitor 27 is controlled, and voltage phiP is applied to the second terminal of the capacitor. When this active boosting circuit is combined with a sense amplifier, the bit line is held at high potential to obtain an active boosting circuit having a small chip area, simple circuit operation, and small power consumption.

Title: Compensating device for height of vehicle
Inventor: KITAMURA KAZUHIKO
IPC: F02M25/06
Filed: 1980-02-04
Abstract: PURPOSE: To compensate the height by a method wherein a regulator setting value of a negative-pressure regulator is changed by bellows expanding and contracting in response to the change in the atmospheric pressure and the further negative pressure is introduced into the air chamber of an exhaust-gas purifying device.  
     CONSTITUTION: When any fluctuation is caused in the atmospheric pressure, air pressure in the internal chamber 1a of No.1 body 1 is changed through the intermediary of communication orifices 2b and 2c of No.2 body 2, the bellows 4 expands by this fall of air pressure, and negative pressure in a negative-pressure chamber 3a is lessened by the force of a spring 17. That is, a piston 8 is actuated to the right by the negative pressure of the negative-pressure chamber 3a and the spring 17. This actuating force overcomes the force of a spring 18, thereby the piston 8 is moved to the right and a valve body 12 is made to contact with the left end of a pipe 11 to stop the introduction of the negative pressure from the pipe 11 into the negative-pressure chamber 3a, while the body 12 being separated from the valve seat part of an upper cover 9 to allow the air to flow into the negative-pressure chamber 3a, whereby the negative pressure in the negative-pressure chamber 3a is lessened.

Title: Idle adjusting device for industrial vehicle
Inventor: SHIMOGAKI MASAAKI
IPC: F02D11/10
Filed: 1991-02-04
Abstract: PURPOSE:To facilitate low speed running by restricting a control lever for increasing an engine speed by a solenoid, changing the speed by the position of a drive shaft, and supplying sufficient cargo handling pressure oil. CONSTITUTION:A fuel injection pump 21 is connected to an accelerator pedal 24 by a control lever 22 and driven. A movable drive shaft 25a is provided in a solenoid 25. By contact of the control lever 22 with the drive shaft 25a, an engine speed is increased by the solenoid 25. By restricting moving the drive shaft 25a by a power supply 26 and a circuit having a switch 27, the engine speed of placing the drive shaft 25a in a full line position and in a virtual line position is changed. Thus, the engine speed at cargo handling time and running time is changed to sufficiently supply the pressure of oil, at the cargo handling time, and to facilitate low speed running at the running time.
Patent JP-S57126535-A (JP)
Title: Engine r.p.m. controlling unit
Inventor: YASUKAWA HEIHACHI
IPC: F02D41/20
Filed: 1981-01-30
Abstract: PURPOSE:To decrease the fluctuation in r.p.m. in an air-inlet unit equipped with a regulator valve in its throttle valve bypass, by controlling the air-rate by the first valve at the engine starting and by the second valve, which operates after the first valve closes, at the idling of an engine. CONSTITUTION:As an engine gets warmed up after the start-up, a pulse motor 7 is driven, and the second valve body 16 moves toward the ''closed''. At this time, since the second return spring 18 is stronger than the first return spring 13, a support 17 of the second valve moves a support 12 of the first valve toward the ''closed'', resisting the spring 13, and closes the first valve body 11 as well as a valve seat 9 at the completion of warming-up. When the first valve 4 becomes ''full closed'', the second valve body 16 compresses the second return spring 18 to vary the clearance between the spring and the second valve seat 15, thereby varying the effective area of a bypass 3. Accordingly, this system controls automatically the effective area of the bypass 3 for the entire region of start-up, warming-up, and idling of the engine, which keeps the fluctuation in the engine r.p.m. less.

Title: Serumless culture medium
Inventor: SHINDOU ATSUNORI
IPC: C12N5/10
Filed: 1992-01-28
Abstract: PURPOSE:To provide a production method for physiologically active substances using a serumless medium. CONSTITUTION:The objective serumless culture medium containing lambda- carrageenan. Using this medium, physiologically active substance-producing cells are cultured to produce physiologically active substances such as tissue-type plasminogen activating factor or monoclonal antibody. This serumless medium, which contains no serum or serum albumin, is inexpensive and stable. With this medium, even when adhesive cells fairly hard to culture are used, debonding of e.g. a microcarrier for the cells from an adherend wall can be suppressed, thus obtaining desired physiologically active substances at amounts equal to or more than those in the case with serum medium.
