Title: Liquid cooling type electric machine
Inventor: MIZUNO HIROKAZU
IPC: H01F27/18
Filed: 1985-09-25
Abstract: PURPOSE:To prevent the lowering of the dielectric strength of gas as well as to accomplish electric insulation economically by a method wherein the cooler located in the circulating path of a liquid phase cooling medium is bypassed, and the temperature of the liquid phase cooling medium is held at the prescribed value or above. CONSTITUTION:A liquid phase cooling medium 4 is sprinkled on a heat generating part with a sprinkler 6, and evaporative cooling is performed with a part of the cooling medium 4. A greater part of the remaining cooling medium is heated up to a high temperature in the state of liquid phase by taking away the heat of the heat-generating part, and it is conveyed to a three-way stop valve 20. When the temperature of the flow-in cooling medium 4 is lower than the set temperature, said stop valve is closed in the direction of a cooler 8, and the flow rate of the cooling medium is reduced, and the flow rate of a bypass 30 is increased. Also, when the temperature of the liquid phase cooling medium 4 is higher than the set temperature, the stop valve is opened in the direction of the cooler 8, and the flow rate is increased, and the flow rate of the bypass 30 is reduced. The cooling medium 4 can be maintained at the set temperature of the stop valve 20 even when the heating power is reduced as above-mentioned. As a result, the pressure of the mixed gas 5 consisting of the vaporized gas of the cooling medium 4 in the chamber 1 and non-condensing insulating gas can be maintained in normal state, the dielectric strength of the gas can be maintained at the prescribed value, and an electric insulation can be performed economically.

Title: Device and method for thermally detecting flow rate, and chemicals feeder
Inventor: ISHIKAWA KO
IPC: G01F1/00
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To measure a flow rate of a fluid with high accuracy, by measuring the flow rate based on a time difference of temperature detection between the upstream side and the downstream side and based on a time for heating the fluid and a time for detecting temperature rise at the upstream side. SOLUTION: In order to obtain a flow rate of a fluid flowing in a tube 4, a heater 5 is disposed on the upstream side of the tube 4 for performing spot temperature rise and two thermistors 6 and 7 are disposed on the downstream side thereof so as to be apart from each other. When the fluid flows in the tube 4 at usual flow velocity, a passing time is determined from the wave shapes of the upstream and downstream thermistors 6 and 7 to detect a moving time of the fluid subjected to the spot temperature rise, and the flow rate per unit time is determined from the passing time, a distance between the upstream and downstream thermistors 6 and 7, and a sectional area of the tube 4.  When the flow velocity inside the tube 4 is decreased, the flow rate per unit time is determined from a time interval between a time when a heater 5 is driven and a time when the fluid subjected to the spot temperature rise passes through the upstream thermistor 6, a distance between the heater 5 and the upstream thermistor 6, and the sectional area of the tube 4, because the wave shape of the detection signal from the downstream thermistor 7 becomes remarkably gentle to decrease the measuring accuracy.

Filed: 1988-08-31
Abstract: PURPOSE:To eliminate an overshoot and to improve the control accuracy by comparing a specific detection output with a specific reference control level and controlling toner concentration according to the comparison output. CONSTITUTION:A vibration waveform component centering on a detection signal curve A corresponding to the toner concentration variation of a two- component developer is added to the curve A to obtain a detection waveform curve B.
