Title: Steam turbine controlling equipment
Inventor: KAMIDATE FUMIO
IPC: F01K23/10
Filed: 1985-03-20
Abstract: PURPOSE:To restrict a sudden steam pressure drop, in a steam turbine driven by the steam generated by means of waste heat from a gas turbine, by closing a steam control valve related to the said steam turbine, according to the amount of the pressure drop, when the front steam pressure of the valve drops. CONSTITUTION:When the operation of either one of steam generators 3a-3c in a combined plant is suspended and when the amount of steam supplied to a steam turbine 8 decreases, the value of a steam pressure measured with a measuring instrument 21, which detects the front steam pressure of a steam control valve 7, also decreases. Then, the output from a subtracter 22, which calculates a difference between said measured value and the value, whose rate of change was restricted to a predetermined value by a rate-of change-limiter 23, turns from zero to a positive signal, while a negative signal is output from the first function generator 24 when the input from the subtracter 22 exceeds the predetermined value. Next, the negative signal, which becomes smaller in accordance with both reduced amount in input and reduced speed, is output from a proportional differential controller 29. According to this negative signal, the steam control valve 7 is closed.

Filed: 1985-03-20
Abstract: PURPOSE:To enable to keep securely air amount flowing into a heat exchanger by installing a motor for a fan capable of rotating reversely and a wind direction detector to control operation of the motor for the fan following wind direction at the outside of an air conditioner room. CONSTITUTION:A wind direction detector 7 is installed as an outside device of an air conditioner room.

Title: Position detecting device
IPC: G01B11/00
Filed: 1992-03-16
Abstract: PURPOSE:To measure a position with precision even though a dark current fluctuates with temperature change or an output varies corresponding to standard voltage variation by deducting the output of a semiconductor position detecting element when an luminous element is turned off from the output when the luminous element is turned on so as to compute a position signal. CONSTITUTION:When measuring is performed, the digital values of the respective terminal outputs of a semiconductor position detecting element 1, under conditions that a luminous element 2 is not turned on, are read and stored in a memory 9. Almost simultaneously the digital values of the respective terminal outputs of the semiconductor position detecting element 1, under the conditions that the luminous element 2 is turned on, are read and stored in the memory 9. An arithmetic means 8 deducts the terminal output obtained when the luminous element is not turned on from the terminal output obtained when the luminous element is turned on so as to compute a position signal after an arithmetic process such as a normalizing computing. The terminal output, when the luminous element is not turned on, is an output equivalent to a dark current, and the dark current is eliminated by this processing and the variable component of a measured value caused by the variation of a standard voltage is also eliminated. The variation of the measured value, caused by the shift of a luminous center, is not allowed to occur either, since the luminous amount of the luminous element 2 is not controlled so as to increase or decrease.

Title: Method for setting up polishing device
Inventor: OCHI HIDETAKA
IPC: B24B1/00
Filed: 1995-02-23
Abstract: PURPOSE: To eliminate the need of a dummy wafer by setting up the reference position of a polishing section in such a way that a polishing means downward in steps while the polishing section is rotated and, when a polishing cloth comes into contact with a freely rotatable chuck table and makes the chuck table to rotate, a CPU detects the rotation of the chuck table and sets up the reference position. CONSTITUTION: A polishing means 2a is moved downward in steps by rotating a pulse motor 11 by means of a pulse motor driver 17 connected to a CPU 8. When a polishing cloth 9 is brought into contact with a chuck table 1 while the cloth 9 is rotated, the table 1 starts to rotate. An encoder 6 detects the rotation of the table 1 and sends the detecting signal of the rotation to the CPU 8 through a servo driver 7. The CPU 8 records the reading of a linear scale 15 when the CPU 8 receives the rotating signal of the table 1 and uses the reading as the reference position of a polishing section 2a. Therefore, the reference position of the polishing section can be set up by directly bringing the polishing cloth 9 into contact with the table 1 without using any dummy wafer nor clearance gauge.
