Title: Method and apparatus for formation of deposit film
Inventor: WATANABE ROKUROU
IPC: C23C14/40
Filed: 1979-09-25
Abstract: PURPOSE:To shorten the processing time and raise the adhesive property of depositing metal to  the surface of a substrate plate by a method in which the substrate plate is concurrently treated by bombardment and undercoat treatments by using a high-frequency coil of a chrominium-containing alloy so that the amount of deposition by the sputtering action of the coil is made larger than  the amount of stain released from the surface of the substrate plate by the bombardment treatment. CONSTITUTION:One end of the substrate plate 10 is connected through an ammeter 12 to the accelerating DC power source 13 outside the deposite film-forming chamber 9, and its one end is  earthed. One end of the earthing wire is connected with the high-frequency power source 14 and  the other end of the power source 14 is connected to the high-frequency coil 15 of the chromiumcontaining alloy. A glow discharge occurs between the high-frequency coil 15 and the substrate plate 10. Also, the depositing metal-vaporizing source 11 is connected to the vaporizing power  source 16. Thus, the surface of the substrate plate is subjected to the bombardment treatment and  at the same time to the sputtering action between the coil and the surface of the plate, whereby  the amount of deposition of metal by the sputtering action is made larger than the amount of stain released by the bombardment treatment, combined with the reason that the watt number of the  high-frequency power source 14 is great and the substrate plate side of the accelerating DC power  source 13 is negatively charged.

Title: Magnetic recording and reproducing device
Inventor: IWAI TOSHIO
IPC: H04N5/93
Filed: 1984-06-15
Abstract: PURPOSE:To attain stable mode shifting from stop to reproduction independently of the existence of an input by applying a false synchronizing signal to a color circuit at the shift of the mode. CONSTITUTION:A switch 24 supplies a false synchronizing signal outputted from a false synchronizing signal generating circuit 25 to a color circuit only at the mode shifting from stop state to the reproducing mode. The circuit 25 can be easily formed by two monostable multivibrators e.g. The switching timing of the switch 24 is obtained by applying the false synchronizing signal to the color circuit during the period from the depression of a reproducing button to the switching of a switch 5 to V-V. Since a circuit for removing an equivalent pulse of a normally vertical synchronizing signal part is included in the color circuit, the flase synchronizing signal may be integer times the horizontal synchronizing frequency. Consequently, the false synchronizing signal can be used by setting up the oscillation frequency of a switching power supply or the clock frequency of a microcomputer in a system control part properly.

Title: Pulsation reducing device for hydraulic pump
Inventor: NOZAKI RYUJI
IPC: F04B11/00
Filed: 1995-05-23
Abstract: PURPOSE: To reduce the occurrence of pulsation during a no-load work by a hydraulic pump and to execute a hydraulic work during a load work without any trouble by a method wherein an adjusting valve for reducing the occurrence of pulsation to openably close a cylinder port communicated with a cylinder chamber on the delivery starting side of a port on the delivery side is arranged at a valve disc. CONSTITUTION: When, during the load work of a hydraulic pump having an adjusting valve 7, pressure oil is generated in an oil passage 47 communicated with a working part, the pressure oil flows through a communication passage 73 and pushes up a piston valve 7c against the force of a stretch spring 71, and a cylinder port 42a in the delivery starting end part of a port on the delivery side is closed by an upper surface 7a. Meanwhile, since, during a no-load work, pressure oil in the oil passage 47 is reduced, pressure oil in a valve chamber 70 is also reduced to the pressure, the stretch spring 71 is against the pressure, and piston valve 7c is lowered to a stopper ring 72. A pressure oil discharge gap H is formed between the cylinder port 42a and the upper surface 7a of the piston valve.  Thus, pressure oil pressurized between port areas (a) is rapidly discharged at the delivery starting end of a port (d) on the deliver side.

Title: Clamping circuit
Inventor: TSUNASHIMA KENICHI
IPC: H04N5/18
Filed: 1985-06-10
Abstract: PURPOSE:To obtain an accurate clamp by using a current mirror circuit that can ignore an Early's effect, compensating the base current of an emitter follower on an output side with high accuracy and constituting a circuit without being influenced by the resistance of a switch. CONSTITUTION:At the current mirror circuit under a low current (be-low several microamperes), the Early's effect makes a mirror ratio worse. At such a case, to ignore the resistance of a clamping switch 8, a collector/base voltage at the current mirror circuit in the base current compensating circuits 3-5 of an input emitter follower is fixed to be set at 1.4V (two diodes) using a newly added transistor and the mirror ratio is brought to 1.0 suppressing the Early's effect at the current mirror circuit. Assuming that a DC current amplification factor (hFE) in an inputting emitter follower and the hFE of a transistor connected to the collector are equal, current same as the base current of the inputting emitter follower is compensated and the current is not on the resistor of the switch for clamping.
