Title: Magnetic shield plate and manufacture therefor
Inventor: KIKUCHI SHIYUUICHI
IPC: H05K9/00
Filed: 1982-05-24
Abstract: PURPOSE:To provide superior shield effect and to obtain a very inexpensive magnetic shield plate as well by a method wherein a high-permeability alloy layer composed iron and nickel as a main body is formed on a substrate composed iron as a main body and a mgnetic shield plate is composed. CONSTITUTION:Nickel plating is directly applied on a substrate composed of  iron as a main body. Then, annealing treatment is applied to a base metal coated nickel plating at 750-950 deg.C under nonoxidizing atmosphere to obtain a shield plate. The iron of the base metal diffuses to nickel on the surface of the substrate and a high-permeability alloy layer composed iron and nickel as a main body is formed on the surface of the shield plate. In this way, the shield effect equivalent to a permalloy of 45% is provided and a very inexpensive shield plate can be obtained.

Title: Digital phase synchronizing circuit
Inventor: TAKAHASHI YASUSHI
IPC: H03L7/00
Filed: 1982-05-26
Abstract: PURPOSE:To extract a clock component from a transmitting signal directly, by using a variable frequency divider, a phase detecting circuit operated at the level change and a control circuit controlling the variable frequency divider. CONSTITUTION:The frequency dividing ratio of the frequency divider 3 is changed with a signal from a phase detector 1 detecting the phase difference between an input transmitting signal and an output of the frequency divider 3 frequency-dividing a signal from a reference oscillator 4 to phase-lock the input transmitting signal and the output of the frequency divider. The detector 1 is constituted so that the phase difference is detected only when the level change in the input signal exists and the output of the phase difference signal in error from the phase detector 1 is prevented. Otherwise, a circuit 5 which increases/decreases the number of pulses fed to the frequency divider 3 without changing the frequency dividing ratio is usable. Thus, a timing signal is extracted directly not through a tank circuit from the transmission signal. Further, this circuit is suitable for circuit integration.

Title: High voltage side switching circuit using semiconductor element for mos gate type power
Inventor: BURUUNO SE NATSUDO
IPC: H03K17/0812
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To easily turn off a switch circuit against its inductive load and to prevent unexpected conduction while avoiding an event of not being turned on according to a command. SOLUTION: The high voltage switch having a MOS gate power device 20 is provided with a control circuit including a control MOSFET 53 connected between a gate and a source of the power device 20. A signal line for an input signal to turn on/off the power device 20 is connected to a level conversion circuit, which is connected to an inverter circuit driving a gate of the control MOSFET 53. Thus, the control MOSFET 53 prevents turning-on of the power MOSFET device 20 in the turn-off process. The turn-off time is reduced by increasing di/dt with a negative clamp voltage to reduce a current flowing during turn-off. The power MOSFET device 20 cannot be turned on whenever the Vcc is low and an output voltage is negative.

Title: Nc machine tool with deburring function

IPC: B23K26/08
Filed: 1986-04-17
Abstract: PURPOSE:To contrive the improved efficiency, lessened manpower and automation of a deburring operation by irradiating laser light by the signal of a detector to detect a burr position. CONSTITUTION:A tool rest 5 is slowly subjected to Z-axis control and the feeler of the detector 8 is positioned to the state in which said feeler contacts only the burr on the outside periphery of an aluminum wheel W. The nozzle end of a nozzle 9 is also brought to the position where the top end faces the burr. The tool rest 5 is further subjected to the Z-axis control and is slowly fed to the spindle side. The feeler of the detector 8 contacts the burr to detect an abnormal projection and the signal thereof is outputted to a laser control device 10. The control device 10 oscillates an oscillator to emit laser light after the time delay when the burr position of the aluminum wheel W comes to the position to receive the irradiation by the nozzle 9 or immediately thereafter. The laser light which is changed in the optical path by a total reflection mirror is irradiated by the nozzle 9, by which the projecting burr is burned away.

Abstract: PURPOSE:To realize the ensurance of isolation between a transmission antenna and a reception antenna while matching the flight performance of an aircraft with the environmental resistance performance by fitting a corrugated plate to a part of the periphery of a body. CONSTITUTION:The corrugated plate 8 having frequency characteristics of a transmission radio wave is fitted to the periphery of a body 1 or an outer casing which is a part of a path of a radio wave between a reception antenna 5 and a transmission antenna 3 of a radio wave transmission and reception device where the transmission antenna 3 and the reception antenna 5 are arranged at a distance on the body 1 or the outer package of the aircraft. The corrugated plate 8 is covered by a cover 9 made of a dielectric having low dielectric constant, for example. Thus, an undesired radio wave passing through various paths on the surface of the body 1 and propagated to the reception antenna 5 is suppressed by forming the shape of the corrugated plate 8 in matching with the operating frequency band. Since the outer structure of the body 1 is unchanged, the effect on the flight performance of the aircraft is small and since no radio wave absorbing body is used, the problem on the environmental resistance performance is less.
