Title: Warming up method and device for gas turbine
Inventor: KUROSAWA SOUICHI
IPC: F02C3/30
Filed: 1978-02-15
Abstract: PURPOSE: To prevent the cracking of high-temperature parts, by utilizing the high- temperature exhaust gas from a starting Diesel engine.  
     CONSTITUTION: The discharge side of the starting Diesel engine 7 is connected through an exhaust pipe 8 to a discharge casing 3 connected to the discharge side of a compressor 1. When a gas turbine starts, a solenoid valve 22 is opened to introduced the exhaust gas from the Diesel engine into the discharge casing 3 through the exhaust pipe 8. The exhasut gas is mixed with air 10 discharged from the compressor 1. The mixture is introduced into the first stage nozzle 4 of the gas turbine. Since the gas turbine is preheated by the exhaust gas from the Diesel engine for the period from the starting to self-running of the turbine, its temperature gradient is decresed. Therefore, the temperature varying rate of the first stage nozzle 4, first stage bucket 5, etc., through which high-temperature gas passes, is reduced. As a result, the purpose is attained.

Filed: 1988-01-28
Abstract: PURPOSE:To take a photograph by a natural pose conforming with the operation of an object to be photographed by providing a prescribed delay time before the photographing operation of a camera is started after an instruction voice is recognized. CONSTITUTION:When a voice is inputted from a microphone 1, a speech recognizing circuit 3 identifies whether its voice is a release or a child's name. In accordance with this input voice, a signal is outputted to a microcomputer 4 through signal lines D0-D2 from the circuit 3. That is, if the input voice is a release, an output becomes '0', '0' and '1', and if said voice is a child's name, the output becomes '0', '1' and '0'. When the output of the circuit 3 is D0='0', the microcomputer 4 starts a photographing sequence. When the photographing sequence is started by inputting a voice, the microcomputer 4 decides the output D1, and in case of D1='0', photographing is started without delay. On the other hand, in case of D1='1', photographing is started by delaying it by the time set by a delay time setting device 16. According to such a constitution, when a child's name is called, the shutter is released just at the time when the child has turned his face.

Abstract: PURPOSE:To enable easy detecting of an omnidirectional reference light, by a method wherein, in a collector for controlling a height of a blade of a bulldozer or other equipment, a surface collecting a reference light is formed in a cylinder, and optical fibers are alined. CONSTITUTION:In order to control a height of a blade (a part for scratching earth) of a bulldozer or other equipment, fan beam such as laser rays is projected as a reference light, and a collector 1, mounted to the blade, detects the reference light. One end of each optical fiber 3 peeps out through a surface 2 of a cylindrical collector 1 at given pitches in a peripheral direction. The other end of the optical fiber is led to a collecting element 4. The aligning pitch of the optical fiber of a point on the periphery of the collector decreases the further downward on the periphery this point is situated, and the alining density increases in a manner described above. As a result, as the irradiation position of the reference light is lowered, a detection light increases, and this permits finding of the position. Additionally, the collector is formed in a cylinder, and thereby it may be irradiated with the reference light from every direction.
