Title: Valve system for internal combustion engine
Inventor: INOUE KAZUO
IPC: F01L3/10
Filed: 1986-04-16
Abstract: PURPOSE:To prevent a valve system from abnormal vibration in high speed revolution by the action of an auxiliary spring further added to a return spring in the high speed revolution on a valve system provided with a cam mechanism for driving intake and exhaust valves. CONSTITUTION:An intake valve 1a is driven by an overhead cam through a first rocker arm 5. While a cam 4 acts on a second rocker arm 6 interlocked with the first rocker arm 5, an arm 12 acts on the second rocker arm 6 with an action force in the same direction as a return spring 26a. A torsion bar 17 is provided in the center bore of a pivot 15 of the arm 12, and is connected to the pivot 15 by oil pressure in high speed of an engine so that a spring force of the torsion bar 17 acts on the arm 12. The arm 12 makes force act on a system in the same direction as the return spring 26a to prevent said system from abnormal vibration due to dancing of the valve system.

IPC: H04B1/7075
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a spread spectrum signal acquisition device wherein the number of times required for calculating correlation value between the sign of a received spread spectrum signal and a pseudo noise code is less. SOLUTION: Conventionally, as shown in S32 and S36, a correlation value between the C/A code received during a predetermined time and that generated on a receiver side is calculated, and, further, using such cyclic integration as added by the amount of three cycles with it, to judge synchronous or a synchronous of the C/A code. With the spread spectrum signal acquisition device, each time correlation values cor1, cor1', and cor2 are calculated, these correlation values are compared with a threshold value, as shown in S42 and S44, and none of them satisfy the threshold value, correlation measurement is stopped before the completion of cyclic integration. Therefore, the number of times of calculating correlation value is appropriately decreased, and the spread spectrum signal can be acquired quickly.

IPC: G01D1/18
Filed: 1979-07-11
Abstract: PURPOSE: To record the data as many as required while extracted gas is exhausted by detecting the moment of gas extraction from bubbles and by starting the recording simultaneously and automatically.  
     CONSTITUTION: When the vacuum vessel 1 for extracting the gas, the mass spectrometer 3 and the vacuum piping 5 are highly vacuumized by the exhauster 2, the  relay 8 emits a signal. When the change-over switch 10 is turned to the timer side and the timer 11 is set to five seconds, for example, the degree of vacuum is reduced by the extracted gas from bubbles of a metal material, the recording by the recorder 4 is started and halted after five seconds by a signal from the relay 8. Also when the change-over switch 10 is set to the opposite side, the extracted gas is exhausted by the exhauster 2, and the recording by the recorder is continued until the degree of vacuum becomes a set value or less of the relay 8 and the signal is stopped. When a lot of gas is exhausted and pressure in the vacuum vessel increases, the relay 9 operates and the recording by the recorder 4 is stopped.

Title: Semiconductor integrated circuit
Inventor: MASUKO KOUICHIROU
IPC: G11C5/14
Filed: 1980-06-26
Abstract: PURPOSE:To save the chip area, by constituting a level holding circuit with two MOSFETs and thus eliminating an MOS capacitor that occupies a large area on a chip. CONSTITUTION:With a rise of refresh pulse phi, a node 14 is charged. Then the node 14 is increased more up to a high level via the gate capacity of an MOSFET15 with a rise of the delay pulse phiD up to a level of power supply voltage VDD. Thus an FET15 conducts strongly and the level of pulse phiD is conveyed to an output node 2 through the FET15. Then the pulse phi is set at a low level when the recharge of node 2 is over, and thus the potential of the node 14 is set at a low level to set the FET15 under a nonconduction state. As a result, the pulse phiD is set at a low level to give no effect at all to the node 2. A pulse having a relation between pulses phi and phiD exists normally within an IC.
