Title: Turbine control device
Inventor: OZONO JIROU
IPC: F01D21/20
Filed: 1978-03-08
Abstract: PURPOSE: To prevent rapid pressure fluctuation of emergency oil during valve test by mounting a damping mechanism in an emergent operation electromagnetic valve, which delays the recovery time of the valve.  
     CONSTITUTION: A rapid operation electromagnetic valve 20 in a turbine control system includes a constricted mechanism 27 which is mounted in a flow circuit 26 of a main spool working pressurized oil as a damping mechanism. When a valve test signal and a rapid operation electromagnetic valve exciting signal are fed to a solenoid 21, a pilot spool 23 moves to the left against a spring 22 to communicate a port a with a port c so that emergency oil is supplied to the right side of it. As the port d, f are closed and the ports f, e are communicated, pressurized oil under a disc damp valve is discharged to close the valve abruptly. After the solenoid 21 is demagnetized, the constricted valve 27 gradually recovers the main spool to change, which allows slow emergency oil supply downward the disc damp valve and may provide little pressure fluctuation of emergency oil in the upstream of a rapid operation electromagnetic valve.

Abstract: PURPOSE:To simplify judgement of the intactness of profile by constituting a conducting layer in a ring type on the peripheral part. CONSTITUTION:In a semiconductor element 1, a low resistance metal layer 2 as a conducting layer is formed by plating process and the like, while a cutting margin 1a for a dicing saw is left. The metal layer 2 is formed in a ring type along the peripheral part of the upper surface of a semiconductor element 1. When a damage is generated in the outer shape of the semiconductor element 1 itself, the damage is generated at the same time also in the metal layer 2. Whether the damage is present is measured as the change of electric resistance of the metal layer 2, by using a pair of probe electrodes 3, 3. Thereby the quality can very easily be judged.

Filed: 1995-02-15
Abstract: PURPOSE: To operate every key of a keyboard only by moving the forearm and hand by using a tool integrally formed of a projection and a strap which is to be put around the palm. CONSTITUTION: The strap part 1 to be put around the palm is made of rubber, and the inner diameter 5 of the strap 1 is a little shorter than the outer diameter of the strap around the base of the fingers on the palm. A projection 3 made of rubber is adhered on the outer surface of the strap 1.

Abstract: PURPOSE:To cause power consumption to be low by turning-on and off a switching means, which is provided in the power source supplying route of an inverter in an output step, and adjusting a through current period to flow between the power source of the output inverter and a GND. CONSTITUTION:An n-MOST 12 to constitute an inverter 10 and an n-MOST 16, which is a transistor for through current limit with a ground, are provided. When an H is inputted to the gate of an n-MOST 14 and an L is inputted to the gate of the n-MOST 16, the n-MOST 16 is turned off and a through current does not flow during the period. Next, when the L is inputted to the base of the n-MOST 14, the potential of a node 9 goes to be the H. Then, when an output is needed, the H is inputted to the gate of the n-MOST 16 and the n-MOST 16 is turned on. Then, the output is removed. Thus, a time, during which the trough current flows most, can be shortened and the energy consumption can be made the lowest.

IPC: H04B3/44
Filed: 1988-02-08
Abstract: PURPOSE:To restrict a fault generated on a transmission line only in a fault section by allowing a relay connected to a part of a feeder between a terminal station of each branch line in each submarine branch device and a submarine earth to control the connection/disconnection of a feeder of a main submarine transmission line to/from the submarine earth connected to the submarine branch device. CONSTITUTION:When a fault is generated at a part shown by a cross mark between submarine branch devices D3 and D<4>, the devices D3, D4 connect a feeder (p) of a main transmission line respectively to submarine earths E3, E4 by allowing current to flow from the terminal stations C3, C4 of the preceding and succeeding branch lines to respective feeders q3, q4. Since the feeders are constituted as mentioned above, power supply between the terminal station A and the device D3 and between a terminal station B and the device D4 can be attained, i.e. communication can be executed in the transmission line other than the fault section. Since both the ends of the fault section are earthed by the submarine earths E3, E4, a cable can be safely picked up to execute repair work without generating the trouble of an accident such as electric shock while securing communication service in other sections.

Thereby the entire concrete 2 is given a high constraining force, so that bearing forces and toughness can be greatly increased.  Therefore, the thickness of the rectangular steel pipe 1 can be reduced for cost reduction.

Filed: 1990-02-07
Abstract: PURPOSE:To increase the sending-out effect of a stored charge from a photodiode part to a charge transfer part and to obtain a solid-state image sensing device whose residual image is low and whose picture quality is high by a method wherein a P-type impurity diffusion layer of a two-layer structure is formed on the surface of the photodiode part. CONSTITUTION:When light is emitted, electrons are stored in an N-type impurity diffusion layer 15 in a photodiode part. Then, when the potential of a readout gate 14 is increased, the electrons are transferred to a charge transfer part 16 under the gate. At this time, the impurity concentration of a P-type impurity diffusion layer 11 in the photodiode part is increased and the impurity concentration of an inner-layer part 12 of the P-type impurity diffusion layer in the photodiode part is lowered. As a result, it is possible to prevent a potential barrier and the well of a potential from being generated. Thereby, the photodiode part can increase the efficiency of a stored charge transfer to the charge transfer part.
