Title: Reheater heating steam system of power generating plant
Inventor: AKATSU JIYUNICHI
IPC: F01K7/22
Filed: 1983-09-16
Abstract: PURPOSE:To eliminate the need of complicated throttle control of a pressure reduction valve and reduce installation cost by providing a heating pipe which carries main steam serving as a heating source into the second-stage reheater and connecting said heating pipe to the exit side of a regulation valve. CONSTITUTION:A heating pipe 22 which carries heating steam into the second- stage reheater 11 is connected to the middle of the line connecting the exit of a regulation valve 14 and a high pressure turbine 5 to each other. Regulation of a turbine load L may be attained by the opening and closing control of the regulation valve 14. If the turbine load is reduced, the regulation valve 14 is throttled to restrict the flow rate of steam into the high pressure turbine 5. By throttling the regulation valve 14, the pressure at the exit of the regulation valve 14 is reduced. As a result, the pressure of the second-stage reheater heating steam which is sent to the heating pipe 22 is reduced along with the temperature at the exit of the second-stage reheater so that the temperature at the exit thereof may be lowered in connection with the turbine load L without the need of a pressure reduction valve.

Title: Servo-control expansion valve
Inventor: KUNUUDO BUAAIEN BUARUBIYORUN
IPC: F16K31/124
Filed: 1990-06-27
Abstract: PURPOSE: To prevent vibration of a main valve closing member by thermally connecting a servo mechanism with the outlet side of the main valve. CONSTITUTION: A servo mechanism 24 is disposed in a chamber 33 located on the outlet side of a main valve 21 and traversed by an expanded and cooled liquid. Since the fluid has lower temperature on the outlet side of the main valve 21, i.e., in the chamber 33, than at the inlet joint 1, generation of steam can be prevented in a working chamber 27 filled with the fluid through a pilot valve mechanism 6. Fluid in the working chamber 27 is cooled externally and kept at a substantially identical temperature as the fluid in the chamber 33. The fluid takes liquid phase at that temperature. Since the liquid is noncompressive, it can prevent generation of a vibration being recognized to prevent vibration of a closing member 23.

Title: Underwater movement apparatus for semiconductor wafer at wet treatment
Inventor: SASAKI NOBUYOSHI
IPC: H01L21/304
Filed: 1990-06-29
Abstract: PURPOSE:To reduce the volume of a water tank and to maintain the high cleanliness of pure water by a method wherein, at a wet treatment before heat-treating a semiconductor wafer, the water tank itself which has housed a cassette is constituted so as to be moved. CONSTITUTION:A water tank 1A is large enough to house one cassette 5; it is supported by two pairs of wheels 12 which are moved on rails 11; it is provided with a movement mechanism 16 which is driven, e.g. by using a motor 13. When the cassette 5 which has housed wafers is inserted in the water tank 1A, the water tank 1A is on standby, e.g. on the left side of a sidewall 2. After its insertion has been finished, the water tank 1A is moved to the right side of the sidewall 2, and the cassette 5 is pulled out from the water tank 1A and transferred to a next process. Thereby, the amount of pure water to be used is reduced to a half or lower as compared with conventional cases. Since the cassette is not moved underwater, the cleanliness degree inside the water tank can be maintained to be high.

Title: Controller for motor
Inventor: KANBARA KOUJI
IPC: H02P27/06
Filed: 1981-10-26
Abstract: PURPOSE:To effectively utilize energy stored in a smoothing capacitor by utilizing the energy as that for performing dynamic braking at a motor. CONSTITUTION:When a motor 5 is decelerated with speed setting means 9 in case the motor 5 is rotated, the output frequency of a power inverter 4 varies smoothly since a softening circuit 10 is provided. Thus, regenerative brake is applied, and the terminal voltage of a smoothing capacitor 3 will rise. When the voltage of the capacitor 3 becomes the prescribed value, overvoltage detecting means 16 produces a signal. In this manner, a base signal from a base signal amplifier 14 to a specific element forming a power inverter 4 is stopped. At this time the motor 5 is dynamically braked by the energy from the capacitor 3.

Title: Driving circuit, electrooptical device and electronic equipment
Inventor: OZAWA NORIO
IPC: G02F1/133
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce stray capacitances which are to be generated among picture data supplying lines and wirings for supplying sampling pulses. SOLUTION: A data line driving circuit 200 generates sampling pulses SR1, SR2,..., SRn by successively shifting an X transfer starting pulse DY according to an X clock XCK. These sampling pulses are to be supplied to a first latch 220 with respective wirings intersecting picture data supplying lines L1 to L9. The first latch 220 latches picture data DR, DG, DB based on the sampling pulses SR1, SR2,..., SRn. Thus, since it is not needed to supply inverted sampling pulses to the first latch 220, the number of wirings can be reduced and then stray capacitances can be reduced.

IPC: H01L21/205
Filed: 1992-06-29
Abstract: PURPOSE:To obtain a III-V compound semiconductor thin film having sufficiently excellent crystallinity and surface homology when the film is grown on a silicon substrate. CONSTITUTION:A method for growing a III-V compound semiconductor thin film on a silicon substrate comprises the steps of heat treating the substrate at a high temperature to surface treat it, lowering a temperature of the substrate to 150-400 deg.C of a low temperature, and introducing, simultaneously upon finishing of lowering the temperature, group V source gas to the surface of the substrate. Thus, a first III-V compound semiconductor thin film is grown on the substrate, raised at its temperature higher than the temperature for growing the first thin film in a state that the gas is introduced as it is or the gas is switched to another group V source gas, and a second III-V compound semiconductor thin film is grown on the first thin film.
