Title: Inverter control method with constant measuring/setting function
Inventor: TAKAGI MASASHI
IPC: H02P21/16
Filed: 1994-05-30
Abstract: PURPOSE:To realize a highly accurate inverter control by performing single phase tests with a plurality of different frequencies, deriving a specific polynomial having frequency variables for the secondary winding resistance and the leakage inductance under respective test conditions, and then determining the resistance and inductance based on the zero-order components. CONSTITUTION:Under no-load of a motor 2, a selector 102 selects a no-load test means 6 and the primary inductance L1 of the motor 2 is determined based on the detection values from a current detector 3 and a voltage detector 4. A DC test means 7 is then selected and the primary winding resistance R1 is determined based on the DC current. Subsequently, single phase test means 81-8n are selected sequentially and the sum of secondary leakage inductances are determined, along with the sum of winding resistances, based on different (n) frequencies thus estimating the leakage inductances L1-Ln. The leakage inductances L1-Ln are employed in an m-order polynomial (m<=n-1) to determine the coefficients A, B, Z and the Z is employed as a true leakage inductance. Similarly, secondary winding resistance R2 and mutual inductance M are determined and the L, M, R1 and R2 are outputted to a control circuit.

IPC: G01J3/45
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To measure a feeble optical spectrum of a minute sample extremely precisely with a simple and small constitution. SOLUTION: The light from a measurement sample 10 is introduced into a Mach-Zehnder type interferometer optical wave circuit 4 through an optical fiber 3. A heater 13 is installed just above a waveguide 12b on one side between two branched waveguides 12a, 12b. When an electric current is sent to the heater 13 by a controller 7, the heater 13 is heated and the refractive, index of the waveguide 12b is changed by the temperature rise, and the optical path length of the waveguide 12b is changed with equal value. A computer 6 gives a command to the controller 7, to change the temperature of the waveguide 12b, and takes in light intensity measured by a photodetector 5, to obtain an optical spectrum distribution of the sample 10.

IPC: B60H1/00
Filed: 1978-11-15
Abstract: PURPOSE:To improve the efficiency of heating by assemblying an auxiliary heat source which can be shifted to move without a block against current wind through a passage. CONSTITUTION:While cooling water of an engine is cool in warming-up, an upright-and-laying-down control mechanism makes a positive characteristic termistor 5 of an auxiliary heat source stand upright to block air current. Simultanously, the positive characteristic thermistor 5 is charged to heat air. Hot air resulting is blasted through a defroster duct 7 and heat duct 8 against a window glass and into the interior of a car. When the engine and cooling water is heated sufficiently, the thermistor operating switch 25 is turned off to stop heating of the positive characteristic thermistor 5. The upright-and-laying-down control mechanism lays the thermistor 5 to store in a cavity 15 for free air passing. Cooling water heated sufficiently actuates a heater core 3 which heats air.

Title: Power supply control system
Inventor: ONO SATOSHI
IPC: G05F1/455
Filed: 1983-08-02
Abstract: PURPOSE:To correct a voltage precisely even if the voltage applied to a load lamp is suddenly changed by controlling a load heater at the time turning on a power supply and holding the peak value of the AC voltage applied to the load lamp to control the phase of the lamp. CONSTITUTION:At the time of turning on the power supply, a CPU1 controls the heater 9 through a solid-state relay SSR8, discriminates and holds the peak value of the AC voltage to be applied to the lamp 6 by a peak holding circuit 5 and controls the phase of the lamp 6 through a TRIAC control circuit 7. When the heater 9 is not controlled, the CPU1 controls the phase of the lamp 6 by a circuit 2 on the basis of the peak value of AC voltage preceding the half period from the current time. When the heater 9 is to be turned on, the succeeding peak value P2 is smaller than the peak value P1 of the AC voltage applied to the lamp 6 before a half period, but sudden voltage change is corrected and power supply is kept constant by reducing the OFF phase T1 of the lamp 6 before a half period less than the current OFF phase T2.

Title: Method and device for cooling liquid
Inventor: SAKANAKA MICHIAKI
IPC: F25D7/00
Filed: 1991-05-17
Abstract: PURPOSE:To cool liquid safely by chemically cooling the liquid using the liquid subjected to the cooling as a refrigerant by applying the phenomenon of a polymer membrane being permeable to liquids and the phenomenon of vaporization of liquids. CONSTITUTION:A liquid A is made to flow on the supply side of a polymer membrane 1 with a good permeability to gases in such a manner as to lower the pressure on the permeated side below the pressure on the supply side. As a result, with increase in the pressure differential DELTAP between the two ends of the membrane 1, the solubility coefficient is increased, making the liquid molecules 4 easy to be taken in; on the other hand, the liquid A is vaporized rapidly and, with increase in the diffusion coefficient in keeping with the concentration gradient DELTAC of the liquid A in relation to the inside of the membrane 1, it becomes easy for the liquid molecules 4 inside the membrane 1 to migrate. Liquid molecules 4 in the vaporized state permeate the membrane 1 in a flow of irreversible change through interstices 3 therein and gather on the permeated side of the membrane 1. On the other hand, the liquid A flocculated on the permeated side of the membrane 1 quickly vaporizes, absorbing heat from the surroundings. Thus the liquid A itself serves as a refrigerant for lowering the temperature to a specified point. This method enables cooling the liquid A in a hazard- free manner.
