IPC: H02H3/26
Filed: 1995-05-09
Abstract: PURPOSE: To make it possible to perform out-of-step detection and periodicity detection by mutually transmitting primary judging data between self-end and opponent-end voltage and reference data, calculating voltage phase difference between the self-end and opponent-end, and judging whether the phase difference passes 180 deg. from leading side or lag side. CONSTITUTION: At a self-end electric station, the self-end voltage is taken in from voltage lead-in means 2A, converted to a digital quantity by analog/digital converting means 3A, primarily judged with reference data by data processing means 4A, and is transmitted as results to the opponent end by transmission means 5A. Also at the opponent end, the opponent end voltage is taken in by a voltage lead-in means 2B, converted into a digital quantity by an analog/ digital converting means 3B, judged primarily with reference data by data processing means 4B, and the results are transmitted to the opponent end by transmission means 5. In the data processing means 4A, the voltage phase difference between its own end and the opponent end can be calculated from the results of the primary judgment from the self-end and the results of the primary judgment transmitted from the opponent end.

Title: Drive control method of self-traveling truck
Inventor: KAKIZAWA SADAO
IPC: G05D1/02
Filed: 1984-05-30
Abstract: PURPOSE:To reduce the maintenance control cost by giving a command to the driver of a self-traveling truck for change of direction or an emergency stop when the time during which a photodetector receives no light at the right and left sides of a guide reflection band exceeds a prescribed period of time based on the center line of said reflection band. CONSTITUTION:The reception of light is interrupted when a photodetector 10 moves to the left side of a guide reflection band 2 and crosses a left edge. Then the reception of light is restarted when the detector 10 is set back onto the band 2 with change of the moving direction of the detector 10. The same action is carried out also with a shift in the right direction. When the time during which the detector 10 receives no light at the right or left side of the band 2 exceeds a prescribed period of time, a command is given to a driver for the conversion information toward the right or left direction in response to the detection of the detector 10 at the right or left side of the band 2. If no light is received after a command is given for conversion of the direction, a central controller delivers an emergency stop command.

Filed: 1988-05-06
Abstract: PURPOSE:To enable dry etching at a low DC voltage and to realize fast etching speed by using gas which contains NH3 for etching gas to etch an organic film formed on a foundation layer selectively. CONSTITUTION:Gas which contains NH3 is used as etching gas to selectively etch an organic film 23 formed on a foundation layer 22. For instance, an aluminum layer 22 is formed on an insulating material layer 21 as a foundation layer and a three-layer resist layer consisting of the organic film 23, and SOG film 24 and an upper resist layer 25 is formed thereon. The upper resist layer 25 is thereafter selectively exposed and patterned. The SOG film 24 is etched by RIE method using the upper resist film 25 as a mask. The dry etching is carried out by using etching gas which contains NH3 and the patterned SOG film 24 as a mask. The aluminum layer 22, the foundation layer, is etched by using the fine patterned organic film 23.

Title: Power supply circuit
Inventor: WATANABE KATSUMI
IPC: H02J1/02
Filed: 1990-04-27
Abstract: PURPOSE:To maintain safety, by providing a common capacitor and adopting a dual system. CONSTITUTION:A generation rate, at which the voltage of a power supply 1 is applied to a case 3, is denoted as P. When a failure rate lambda, at which a common capacitor 5 fails in short circuit mode, is 1 (FIT), a failure rate lambdat, at which a capacitor C1 and the common capacitor 5 fail simultaneously in short circuit mode, comes into lambdat 2Xlambda1XlambdaXt, where t denotes an operating time. When the operating time t is 10 years, i.e., about 10<5> hour, P comes into P=1/10X1/10X2X1/10<9>X1/10<9>X10<5>=2X10<-15> (FIT). Therefore, even if the capacitor C1, C2 for absorbing noises fail in short circuit mode, unless the added common capacitor 5 fails simultaneously in short circuit mode, it is not caused that the voltage of the power supply 1 is applied to the case 3. Thereby, safety can be maintained.

Abstract: PURPOSE: To remove automatically solids adhered to the inner surface of a gas- introducing pipe at the gas outlet, by operating a solid-removing mechanism installed in the gas-introducing pipe by utilization of kinetic energy of high speed gas sent pressurized through the pipe.  
     CONSTITUTION: A vertical shaft 6 is attached to a supporting rod 5 fixed horizontally in a gas-introducing pipe 2, and a rotator 7 is set to the lowr end of the shaft 6.

The rotator 7 is rotated by the kinetic energy of  high- speed gas sent pressurized through the gas-introducing pipe 2, with its side surface of the lower part contacting with the inner surface of the pipe at the gas outlet 3 by centrifugal force because the lower end of the shaft 7 is not fixed to the pipe 2, so that the rotator 7 removes solids adhered concentrativly to the part.

Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To provide the facsimile equipment by which power supply is stopped in the standby state so as to save energy and power is stably supplied at start of power supply. SOLUTION: A transistor(TR) 1 is made nonconductive when a power supply control signal is at a low level in a power supply changeover section so as to stop supply of a system power supply (+5V). When the power supply control signal is switched to be a high level in this state, a capacitor C1 is charged at a prescribed high voltage via a resistor R1 as shown in an arrow (1) and a voltage level at a point A rises gradually. As the voltage level at the point A rises, the TR 1 is gradually made conductive and the TR 1 arises gradually the system power supply (+5VE) from the power supply section from 0V to +5V depending on the conduction state to supply the resulting power as the system power supply.  When the standby state is selected again and the power supply control signal is switched to be a low level, the charge in the capacitor C1 is momentarily discharged via a resistor R2 and a diode D1 as shown in an arrow (2) and the TR 1 is momentarily made nonconductive to stop the supply of the system power supply to each section.

Title: Supporting device of vertical shaft water-wheel generator

IPC: H02K5/00
Filed: 1981-07-17
Abstract: PURPOSE:To maintain the support of a bearing in good condition for a long period by a method wherein supporting plates fixing a disc-shaped bracket on a concrete floor are formed by wall thin and broad bending bodies and the supporting plates are installed so that the width direction may go along the tangential direction of the bracket. CONSTITUTION:A disc-shaped bracket 6 holding a guide bearing is fixed on a concrete floor 14 through a plurality of supporting plates 15. At that time, the supporting plates 15 are formed as bending bodies having thin thickness and broad width and also installed so that the thickness direction may go along the diameter direction of the bracket 6 and the width direction may go along the tangential direction. This absorbs the deformation in the diameter direction by the thermal expansion of the bracket 6 and also allows high durability to the force in the tangential direction by unbalance. Thus, the guide bearing can be maintained with good condition for a long period.
