Title: Load control device for combined cycle plant
Inventor: ONO TORU
IPC: F01K23/10
Filed: 1991-01-30
Abstract: PURPOSE:To obtain better comprehensive load control characteristics in comprehensive load control of a combined cycle plant. CONSTITUTION:A subtraction means 18 subtracts an output value (e) from a steam turbine output value detecting means from a comprehensive load reference value (a) set by a comprehensive load reference value setting means. A control means for a gas turbine controls load on the gas turbine according to an output value from the subtraction means. By this, the gas turbine can be controlled, in the control system, always with an output value from the steam turbine taken as the same as disturbance. Thus affection of characteristics of a steam turbine which depends largely on the gas turbine and control characteristics peculiar to the steam turbine on comprehensive load characteristics can be decreased. Accordingly, the control characteristics of an overall combined cycle plant is improved.

IPC: B22D13/10
Filed: 1979-06-20
Abstract: PURPOSE: To enable the obtaining of the casting of sound structure by using pure copper or copper alloy for the portion of a high heat capacity in the die of centrifugal casting.  
     CONSTITUTION: In casting a pipe-form casting having flanges or the like by a centrifugal casting means, pure copper or copper alloy is used for the die material of the portions of different heat capacities in order to prevent the depth of the recesses owing to "shrinkage" of the inside surface of the flange portions produced in the portions of different heat capacities or the porosities of these portions from becoming large. For example, with the iron-made die 2 for obtaining a casting product 1, the band die 4 which forms the outside surface of the flange portion 1a and is also the opening end band of the die 2 is formed by pure copper or copper alloy and the molding die 3 formed likewise by pure copper or copper alloy is buried in he die portion forming the inside surface of the flange portion 1a. These accelerate the cooling of the portions of a hight heat capacity and enable the balancing of cooling.

Title: Total reflection type optical waveguide switch
Inventor: KAMATA YOSHIYUKI
IPC: G02F1/313
Filed: 1990-03-27
Abstract: PURPOSE:To obtain a total reflection type optical waveguide switch capable of reducing the generation of an excess loss by forming one of plural projection side optical waveguides so that the deviation of an optical path induced by a refractive index changing area in a through state is corrected. CONSTITUTION:One of the projection side optical waveguides 1b, 2b, 2b' is formed so that the deviation of the optical path induced by the refractive index changing area in the through state can be corrected. Since light in a through state generates an optical path deviation such as an axial deviation or an angular deviation in a process passing the refractive index changing area, an excess loss is generated, but since the formation positions of the waveguides 1b, 2b, 2b' are corrected only by a deviation value corresponding to the optical path deviation, the excess loss due to the optical path deviation can be reduced. Thus, the low loss and total reflection type optical waveguide switch capable of reducing excess loss can be obtained.

Title: Motor drive circuit
Inventor: KUBO NAOMOTO
IPC: H02P6/28
Filed: 1994-04-19
Abstract: PURPOSE:To make a Lo limiter circuit operate for the reduction of electromagnetic noises regardless of increase/decrease in motor driving current. CONSTITUTION:When voltage generated in a resistor 21 is fed to the base of a p-n-p type transistor 62 and constant current is passed across the collector and emitter of the same transistor 62, emitter voltage is increased or decreased according to increase or decrease in motor driving current. To cope with this, this voltage is used as the base voltage VL of each of the n-p-n type transistors 51-53 in a Lo limiter circuit 55. This makes the Lo limiter circuit operate without fail and thus reduces the generation of electromagnetic noises if motor driving current increases and the lowest level of the terminal voltage of each phase is thus increased.
