Title: Method for reducing warming-up steam quantity in high-pressure steam condenser
Inventor: ARITAKA HITOSHI
IPC: F01K11/04
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing a warming-up steam quantity in a high-pressure steam condenser, by which a quantity of steam to be allowed to flow continuously for warming up the high-pressure steam condenser can be reduced to utilize effectively the energy of steam. SOLUTION: In this method for reducing a warming-up steam quantity in a high-pressure steam condenser, pressure in a steam receiver 2 in boiler turbine power generation equipment provided with a high-pressure steam condenser 5 is detected. In the case where the pressure thus detected is lower than a predetermined value and the high-pressure steam condenser 5 is on standby, steam in a minimum quantity required for warming-up is allowed to flow into the high-pressure steam condenser 5 in a low-pressure mode.  On the other hand, in the case where the pressure thus detected is higher than the aforementioned predetermined value and surplus steam is accumulated in the steam receiver, the high-pressure steam condenser 5 is shifted to a high-pressure mode, and the steam quantity flowing thereinto is increased more than that required at the time of the standby state of the high-pressure steam condenser 5 to be condensed, thus reducing the warming-up steam quantity.

Filed: 1987-06-23
Abstract: PURPOSE: To reduce the number of parts to attain quick operation by operating wired OR between outputs of comparators facing each other by coding transistors TRs to perform gray coding of bits other than the most significant bit.  
     CONSTITUTION: A first comparator array 100 and a second comparator array 200 are arranged in parallel, and reterence voltages of the comparator array 100 and the comparator array 200 are continuously given by return, and an encoder matrix is arranged. Wired OR between outputs of comparators facing each other is operated by coding TRs 311∼324 to perform gray coding of bits other than the most significant bit.

Title: Method and instrument for copying measurement
Inventor: KOJIMA KOKI
IPC: G01B9/02
Filed: 1988-06-22
Abstract: PURPOSE:To perform accurate copying measurement in a non-contacted state by adopting an optical heterodyne interference method and, at the same time, eliminating the influence of a Doppler shift. CONSTITUTION:Laser beam which is outputted from a semiconductor laser 1 and frequency-modulated to triangle waves having the same rising and falling inclination as shown by (A) of the figure is split into two parts by means of a beam splitter 3. An object 5 (or a reference reflecting body) moving at a fixed speed is irradiated by one part (or the other part) of the laser beam and a photoreceptor element 6 is caused to interfere with the reflected beam from the object 5 so as to obtain frequency interference signals against the distance to the object 5 and the moving speed and direction of the object 5. The frequency of these interference signals becomes the sum (or the absolute value of the difference) of the beat frequency and Doppler shift frequency at the rising (or falling) selection of the triangular modulated waves. Therefore, by making addition or subtraction based on the frequency corresponding to the section by means of a processor 7, the influence of the Doppler shift frequency is eliminated and the successively changing distance to the object is accurately measured based on the frequency.

Abstract: PURPOSE:To reduce the burden of processing at a central control part. CONSTITUTION:When off-hook information is received from a multifunctional telephone set (MFT) 2 while the channel state of the MFT 2 is idle, a multifunctional telephone set interface card(MFTi/f) 3 transmits 'OFF' information to a central control part (CC) 5 and transmits the request of a handset channel to the MFT 2. As a result, the MFT channel state is changed into handset speaking. Then, the information excepting for call origination/cutoff information from the MFT 2 is exchanged just between the MFT 2 and the MFTi/f 3, and the channel of the MFT 2 is controlled so that all the information can not be exchanged between the MFT 2 and the CC 5.
