Title: Auxiliary steam pressure controller
Inventor: KISHIDA KENJI
IPC: F01K23/10
Filed: 1990-11-22
Abstract: PURPOSE:To restrict a drop of pressure of an auxiliary steam header to the minimum so as to obtain a stable pressure of the auxiliary steam header by connecting, to an auxiliary steam comprehensive controller, preference devices provided for shafts on the way from the auxiliary steam comprehensive controller to pressure regulating valves. CONSTITUTION:An output signal 30 as a calculation signal from an auxiliary steam comprehensive controller 29 is inputted into a preference device 31 disposed on an output line of an auxiliary steam pressure regulator 17 of a plant shaft and another preference device disposed on an output line of an auxiliary boiler generation steam flow regulator. An auxiliary steam pressure of each plant shaft is detected by an auxiliary steam pressure transmitter 16, and is calculated in comparison with a set value by the auxiliary steam pressure regulator 17, whereby the resultant signal is normally introduced directly to an auxiliary steam pressure regulating valve 13. The preference device 31 is adapted to distribute auxiliary steam as a whole of a unit. Therefore, it is possible to restrict a drop of a pressure of an auxiliary steam header to the minimum.

Title: Back light of display
Inventor: KOBAYASHI MASAYUKI
IPC: G02F1/133
Filed: 1987-12-16
Abstract: PURPOSE: To prevent an irregularity in the illuminance of a diffusion plate and an irregularity in color light of radiant light from being generated with simple constitution by adhering a reflecting film onto the surface of a fluorescent lamp as the back light on the side of a diffusion plate. CONSTITUTION: The reflecting film 6 is adhered onto the surface of the glass bulb 5 of the fluorescent lamp 3 on the side of the diffusion plate 4. Therefore, light which is projected directly on the diffusion layer 4 as to light emitted by the fluorescent lamp 3 is light transmitted through the reflecting film 6 and the transmissivity of the reflecting film 6 to visible light can be varied with the distance between the fluorescent lamp 3 and diffusion layer 4. In general, the transmissivity is about 50%, so light which is diffused by the diffusion plate 4 and emitted out becomes uniform in illuminance to provide preferable lighting.  Light which is emitted to the opposite side of the fluorescent lamp 3 from the diffusion plate 4 is emitted directly by the glass bulb 5 since the reflecting film 6 is not present on the opposite side of the glass bulb 5 of the fluorescent lamp 3 from the diffusion plate 4, and then reflected by the reflecting plate 2 of the display device 1 and projected on the diffusion plate 4. Consequently, the light emitted by the diffusion plate 4 has neither the irregularity in illuminance nor the irregularity of colors and high-illuminance uniform light emission becomes possible.

Filed: 1987-12-16
Abstract: PURPOSE:To measure a DC component with good accuracy, by connecting a parallel circuit of an AC earthing condenser and a DC current measuring apparatus between the neutral point of a GPT transformer and the ground and further connecting a cable shield layer to the parallel circuit on the ground side thereof. CONSTITUTION:The conductor 2 of a power cable is in a live wire state in the state connected to a high voltage bus 4 and an earth type instrumental transformer GPT 5 is connected to the bus 4.

Title: Supervisory signal reception circuit
Inventor: ISHIZU WATARU
IPC: H04Q1/30
Filed: 1989-12-05
Abstract: PURPOSE:To improve the processing capacity of a high order device by Schmitt trigger-operating the output of an integrating circuit clamping upper-bound/ lower-bound integral values in which the make continuous time of a supervisory signal is set to be positive and a brake continuous time as negative by means of the clamps values of upper-bound/lower-bound and outputting a square wave. CONSTITUTION:The supervisory signal inputted to a terminal 1 is integrated in the integrating circuit 3 with the make continuous time as positive and the brake continuous time as negative. When the integral value reaches a prescribed positive value (a), it is clamped to (a). When the value reaches a prescribed negative value -a, it is clamped to -a. The output of the circuit 3 is inputted to a limiter circuit 4 and the output of the circuit 3 is Schmitt trigger-operated by the positive value (a) and the negative value -a, whereby the square wave is outputted to an output terminal 2. Thus, the processing capacity can be improved by permitting the high-order device to periodically supervise the output of the terminal 2 and to view the change of the state of the supervisory signal.

Title: Proportional pressure control valve
Inventor: HASHIDA KOICHI
IPC: G05D16/20
Filed: 1991-11-29
Abstract: PURPOSE:To control a high pressure with a small energizing force by energizing a spool in a direction against the liquid pressure applied to the spool by a sectional area difference and arranging two annular seals on a spool shaft. CONSTITUTION:Seal parts 3 and 4 are constituted so as to open or close valves between a high pressure source port 5 and an output port 7 and between the output port 7 and a low pressure source port 6 in accordance with the movement of a spool 2. A spool shoulder part diameter A2 of the valve part on the low pressure source port side is made larger than a slide diameter A1 of the spool 2 by a prescribed extent. An energizing means 8 energizes the spool in a direction against the liquid pressure due to this sectional area difference. Therefore, the seal part 3 between the high pressure source port 5 and the output port 7 is opened when the pressure of the output port 7 is lower than the pressure determined by the pressure difference corresponding to the energizing force, and the seal part 4 between the output port 7 and the low pressure source port 6 is opened when the pressure 7 of the output port 7 is higher. Thus, the pressure difference is kept at a low pressure corresponding to the energizing force.
