Title: Sampling method
Inventor: OTA TOSHINORI
IPC: H03M1/12
Filed: 1990-03-26
Abstract: PURPOSE:To shorten the renewing time of a waveform by finely dividing a rough part showing the outline of a waveform in succession to preferentially collect the same. CONSTITUTION:When the lowest and highest levels of the analogue signal outputted from a D/A converter 14 are adjusted so as to respectively coincide with the lowest and highest level (V) of a signal C, in such a case that output levels are respectively V/4, V/2 and 3V/4, the points X, Y, Z where the signal C coincides with the levels become the points of time when the data of N/4, N/2 and 3N/4 are respectively sampled. When outputs MSB, LSB are allowed to correspond to the inputs LSB, MSB of the converter 14 and all of other signals are connected in reverse correspondence when the output of a counter 13 is supplied at every gate signal in order to generate a signal in the converter 14, sample timing is obtained in the order of N/2, N/4, 3N/4 and N/8. When an S/H+A/D circuit 9 is operated at this edge, data are outputted in a desired order. By this method, the outline of a waveform can be indicated at an early stage and the renewing time of the waveform to a new waveform is shortened.

Title: Cooker
Inventor: HOTSUTA TETSUZOU
IPC: F24C7/08
Filed: 1983-04-25
Abstract: PURPOSE:To make food serve at the condition as palatable as possible by a method wherein the food is not rendered to be positively raised its temperature up to the room temperature even when the temperature to keep warm is lower than the temperature to ventilate a heating chamber, for example, the room temperature. CONSTITUTION:Except for the arrival of the food temperature to the set heating temperature or only when the output of a second AND gate AND2 is kept high level, a first AND gate AND1 outputs a low level signal, because a first inverter INV1 inputs a low level signal to the first AND gate AND1. However, when the food temperature reaches the set heating temperature, two high level signals are inputted to both the inputs terminals of the first AND gate AND1 and consequently a high level signal is outputted from the first AND gate AND1. As a result, a first transistor TR1 is turned OFF. Accordingly, after the food temperature reaches the heating temperature, a low level signal is inputted to the reset input terminal R of a first RS flip flop FF1 and a low level signal is outputted from the output terminal Q of the first RS flip flop FF1 and a main switch MN is turned OFF, resulting in prohibiting subsequent operation for keeping warm and subsequent ventilation of the interior of a heating chamber.

Title: Vapor-liquid contactor
Inventor: WATANABE TAKEKATA
IPC: B01D3/20
Filed: 1978-06-19
Abstract: PURPOSE: To prevent the function of the title contactor from deteriorating, even if the contactor is inclined or swinged by a wind and waves, by setting guide walls provided with damping plates having upper openings between bubble cap lines on a plurality of shelves in the contactor at positions higher than descending pipes.  
     CONSTITUTION: In a vapor-liquid contactor used in an ocean plant, etc., a liquid overflowing from the upper end of descending pipe 2 flows in a zigzag direction along guide wall 6 by a plurality of times and descends to the next shelf. Thus, the time of contact between the liquid and air bubbles blown up from bubble caps 4 is elongated to enhance the distillation performance. When the contactor inclines in the X-X direction, movement of the liquid is restricted with wall 6 to make a difference in liquid level small, and gas seal of the liquid surface is secured. To the inclination in the Y-Y diretion damping plates 5 restrict movement of the liquid, so the liquid moving speed is decreased, and the inclined construction and tower body 1 are restored before the liquid finishes the movement, thus preventing gas channeling.

Title: Cleaning method for pipeline of reduced hot water in geothermal power generation and cleaning device
Inventor: SONOBE TAKIO
IPC: F01K21/06
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning method which can reduce kinds and number of pigs for cleaning, and remarkably improve operation ratios of cleaning devices. SOLUTION: Flow of hot water in a first branch pipe 13 is stopped. The hot water is supplied to a piglauncher 30 through a second branch pipe 14. A reduction main pipe 15 is communicated with a pigreceiver 70 by switching a three-way changeover valve 60. Pig is applied from the piglauncher 30 due to the function of the hot water. The reduction main pipe is cleaned by the pig. The pig is recovered by the pigreceiver 70, while the hot water is bypassed to a reduction well 18. It is thus possible to optionally clean the pipe during operation of the power generation plant, and perform cleaning under the condition of thin scale. Cleaning cost can thus be reduced remarkably.
