Title: Temperature controller for hot and chilled water generator and temperature controlling method therefor
Inventor: NITO MASAMI
IPC: F25B15/00
Filed: 1995-03-24
Abstract: PURPOSE: To control the temperature of hot or chilled water by providing a control unit which calculates the predetermined temperature correction amount of hot or chilled water for the detected temperature of heating medium, adds the correction amount to the predetermined set temperature of the hot or chilled water and sends an operation signal to heating means based on the new-set temperature. CONSTITUTION: A temperature detecting means 4 detects the temperature of the heating medium 30 of a heating means 14. The temperature correction amount of predetermined hot or chilled water 27 is calculated corresponding to the detected temperature, added to the predetermined set temperature of the water 27, and the new set temperature is calculated. Since a control unit 6 for operating the means 14 based on the new set temperature is provided, if the temperature of the medium 30 is raised, the temperature is detected, and the predetermined temperature correction amount of the water 27 corresponding to the detected temperature is added to the predetermined set temperature of the water 27.  Since the new set temperature can be temperature controlled, the load of a hot and chilled water generator 1 is reduced, the generated heat quantity of the means 14 is suppressed, and the temperature of the medium 30 can be lowered. Accordingly, the temperature of the water 27 can be controlled.

Title: Controlling of load in turbine
Inventor: NIKAWARA SEIITSU
IPC: F01D21/14
Filed: 1982-04-21
Abstract: PURPOSE:To keep an instruction output as long as possible by a method wherein wheather or not the metering of a steam control valve is possible is judged in reference to a quantitative relation between the load of a turbine and the requirement of load from a central power supplying station. CONSTITUTION:When a water level is rised in more than two units of high-pressure feed water heater 6, 8 and 10 at a low pressure side in the same system, the steam extraction for the high pressure feed water heater 8 and 10 is terminated. At this time, wheather or not the metering of a steam contol valve 24 for turbine inlet steam is judged in response to the load in the turbine and the instruction requiring value sent from the central power supplying station, and if it is possible to have a metering of the control valve, the control valve 24 is metered and in turn if not the steam extraction for the high pressure feed water heater 6 at the highest pressure side is terminated. In case of terminating of the steam extraction for the high pressure feed water heater, a distribution of the pressure for each of the stages is disturbed and in particular the load at the highest pressure stage shows an excessive disturbance of the pressure distribution. Thus, even the steam extraction for the high pressure feed water heater at the highest pressure side is terminated, resulting in decreasing the limited load and keeping the rated load as much as possible.

IPC: G01N1/22
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a pre-treating device for gas analysis which can enable a gas analyzer to continuously perform analysis. SOLUTION: A sample gas is introduced to the upper pot 21 of a first stage A and then sent downward through a wetted wall 22. When flowing-down water comes into contact with the sample gas on the wall 22, solid particles contained in the sample gas move to the water. The sample gas is then extracted through the top of a first circulating tank 23, introduced to the upper pot 24 of a second stage B, and sent downward through another wetted wall 25. When the sample gas is sent downward, the gas and water are forcibly sent downward by means of a pot 26 equipped with an aspirator. The sample gas then reaches the upper pot 28 of a third stage C and is subjected to the same treatment as that performed in the second stage B. After the third stage C, the sample gas reaches the upper pot 32 of a fourth stage D and is subjected to the same treatment as that, in the first stage A.  The sample gas from which solid particles are completely removed through the treatment in the four stages is sent to a gas analyzer.

Abstract: PURPOSE:To surely and simply perform determination for waveforms so as to aim at enhancing the manipulatability of an acceleration pulse meter by eliminating parts of an acceleration pulse waveform above a reference line, and by inverting parts thereof below the reference line so as to set them thereabove. CONSTITUTION:When a finger is inserted in a blood sensor 11, light emitted from a light emitting element 2 transmits through the finger as well as blood flowing therein and reaches a light receiving element 3. In this phase, variations in the quantity of blood which increases and decreases in accordance with the pulsation of the heart and shields the light, is detected electrically by the light receiving element 2, and are differentiated to the secondary order by an acceleration pulse wave converter 4 so as to be converted into an acceleration pulse waveform which is then led to a waveform reverser 5 that eliminate parts of the acceleration pulse waveform above a reference line while inverting parts thereof therebelow so as to set them thereabove, and indicates them on a display 6. If a trough (b) is hidden below the reference line so as to be invisible, it means a waveform indicating satisfactory blood circulation. However, a crest (c) is higher than a crest (a), it means a waveform indicating a slightly deteriorated blood circulation.
