Title: Oil jack
Inventor: YOSHIZAWA SHIGERU
IPC: F15B11/02
Filed: 1979-11-13
Abstract: PURPOSE: To prevent the occurrence of cavitation, by a method wherein, when an oil jack returns after a driving stand of, for example, a cabover type vehicle inclines, one of sweeping chambers of a cylinder becomes a negative pressure resulting from a rapid fall due to a tare.  
     CONSTITUTION: When a driving stand 8 is tilted forward by means of an oil jack 1 from a normal position, a switch valve 14 is set in a position 14A, and a manual pump 15 is actuated. A discharge pressure oil of a pump 15 pushes and opens a pilot check valve 13b, and is fed to a sweeping chamber 11b. A valve 13c is released with an oil pressure in a line 11g, and the oil pressure is fed to a sweeping chamber 11b as well. A piston 12 moves to the left with a difference in a pressure acting area, and the jack 1 expands. In the meantime, when the driving stand 8 is lowered from a tilting condition, the switch valve 14 is set in a position B. A return oil from the chamber 11c is throttled with a throttle resistance thereupon, and the valve 13c is opened. This prevents the chamber 11b from becoming a negative pressure.

Title: Bias sputtering device
Inventor: HORIUCHI MITSUAKI
IPC: H01L21/285
Filed: 1986-06-25
Abstract: PURPOSE:To form a film having good adhesiveness on a substrate surface without deteriorating film quality by detecting substrate current and providing a controller to control the density of the plasma generated near the substrate based on the detected current. CONSTITUTION:The inside of a chamber 1 is evacuated to a high vacuum by a discharge port 8 and gaseous Ar is introduced through a gas supply port 7 into the chamber until the prescribed degree of vacuum is attained. While an upper electrode 2 is heated by a heater 12, electric power is impressed from a negative power source 5 to a lower electrode 3 and electric power is also impressed simultaneously to the upper electrode 2 from a negative power source 4 to set the electrode at a required bias. The plasma is thereby generated between the two electrodes 2 and 3 and sputters a target T, thus forming the film on the surface of a substrate W. The current at the upper electrode 2 is measured by an ammeter 10 and a controller 11 makes the feedback control of the electric power of the negative power source 5 based on the measured value so that the current value attains approximately the prescribed value or above. While the bias at the upper electrode 2 is thereby held constant, the plasma density is controlled and the quantity of the ions flowing to the substrate W is increased.

Filed: 1985-07-03
Abstract: PURPOSE:To increase an estimation accuracy by estimating the azimuth of a target sound source by the beam output of an adaptive beam former (queuing ABF) with a high S/N ratio. CONSTITUTION:A signal from a target sound source is received by a receiver array 10 and a queuing beam is formed by a nonadaptive beam former (queuing CBF) for the output signal of the receiver array 10. An approximate azimuth of the target sound source is obtained using a queuing beam output. Since the queuing beam is formed by a queuing waiting ABF 70 with a high S/N ratio at a beam output only in the minimum azimuths necessary for an interpolation using the information of the azimuth of the target sound source thus obtained whereby the azimuth of the target sound source is estimated, the accurate azimuth of the target sound source can be estimated.
