Title: Step-out detecting device in centerless synchronous motor
Inventor: UEDA HIDEFUMI
IPC: H02P6/18
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To detect step-out in any states such as high speed, large current, regenerative mode or stop condition by performing step-out detection when the effective value of current of a stator winding exceeds a judging level, and a power factor angle between the stator winding and a voltage applied to a stator winding has reached a particular value. SOLUTION: An effective value of a current of a stator winding can be determined by detecting an instantaneous current value flowing the stator windings of V-phase and W-phase from current detectors 3 and 4. Also, based on the detected values detected from a DC power supply voltage detector, an arithmetic device 1 controls ON/OFF time to six power transistors, the arithmetic device 1 controls and detects the effective value of voltage applied to the stator windings, and the power actor angle between the voltage applied to stator windings and stator winding current can be determined. Therefore, when the effective value of current of stator winding exceeds the preset judging level and the power factor angle has a value close to 90 deg., the step-out detection can be performed for any state of step-out.

IPC: A61K6/04
Filed: 1985-05-20
Abstract: PURPOSE:To obtain a dental Ag alloy having improved physical properties and corrosion resistance by adding specified amounts of Cu, Ge and Zn and a very small amount of Ir and Rh to Pd and Ag as essential components. CONSTITUTION:This Ag alloy consists of, by weight, 10-35% Pd, 10-25% Cu, 0.1-5% Ge, <=5% Zn, 10-1,000ppm Ir and Rh, and the balance Ag.

Filed: 1995-04-28
Abstract: PURPOSE: To rapidly judge failures according to failure judging time that corresponds to fluctuations in pump application voltage by setting the failure judging time to be variable based on the applied voltage detected. CONSTITUTION: When a negative-pressure detection signal, i.e., a sensor output, is input to an input interface 2 of a control unit 1, a CPU 3 processes the signal and, when judging that negative pressure has reached its lower limit value, outputs a pump drive signal via an output interface 4 so that driving of a pump is started; when judging that the negative pressure has reached its upper limit value, the CPU 3 outputs a pump stopping signal to stop the pump. If some failure such that no negative pressure detection signal is output occurs in a pump drive and control system or the like which comprises sensors, etc., a pump application voltage detection signal is read by the CPU 3, and failure judging time based on the pump application voltage is read from a ROM 6.

Filed: 1981-07-08
Abstract: PURPOSE:To improve radiation of heat generated by an electronic part by inserting its lead into the slit of a tubular radiator which is fixed in the vicinity of the main body. CONSTITUTION:An electronic component part lead 2 is inserted into a slit 8 of a high thermal conductivity tubular radiator 7 which is fixed in the vicinity of a part body 1. Heat generated by the body 1 is transmitted via the short lead 2 to the radiator 7 from which it is radiated. Since both the inner and outer surfaces of the tubular radiator 7 can be utilized for heat radiation, a large amount of heat radiation can be obtained even with its small occupied volume. The use of a larger tube radiator will increase the radiation area, the chimney effect, and hence heat radiation.

Title: Energy detecting device, thermal function device and driving method therefor
Inventor: TANAKA AKIO
IPC: H01L27/14
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a thermal function device of higher thermal reaction speed at lower price and smaller size. SOLUTION: When an infrared ray is irradiated toward a diaphragm 2, a heat is generated to increase the output of a thermoelectric conversion element 4. Since a reference thermoelectric conversion element 5 is not irradiated with infrared ray, an output signal does not change. A difference between both outputs is detected at a calculation amplifier 19, which is amplified and outputted as a compensation signal. The compensation signal is supplied to a measuring device 21 through a noise filter 20. The measuring device 21 calculates the infrared ray irradiation amount and heating amount of the diaphragm 2 from the compensation signal. At the same time, the compensation signal is supplied to a thermoelectric conversion means 3.  Supplied with the compensation signal, the thermoelectric conversion element 3 so operates as to cancel the energy application to the diaphragm 2, resulting in a constant temperature.

Abstract: PURPOSE:To eliminate the water-proof processing of a circularly polarized wave/linearly polarized wave converter and to improve the cross polarization characteristic by covering an opening of the primary radiator of the converter with a foamed styrol and applying insert forming to the converter with a resin. CONSTITUTION:A front side of an opening 22 of a primary radiator 21 is covered with an expanded polystyrene 24 and a foamed resin cover 26 is molded by insert molding with a resin while leaving only a part of a connector 25 of a main body 20. A radio wave 23 from a satellite or the like is made incident onto a front side of the foamed resin cover 20 and received by the opening 22. The attenuation of a radio wave 23 made incident onto the foamed resin cover 26 is improved by selecting a foaming rate of the foamed resin cover 26 to be a specific value such as 60% thereby making the dielectric constant to be equal to that of air. Furthermore, since the reflection of a radio wave onto the foamed styrol 24 of the opening 22 of the primary radiator 21 and the foamed resin cover 26 is reduced, the reflected wave returned in the inside of the primary radiator 21 is reduced to improve the cross polarization protection ratio.

Abstract: PURPOSE:To capture iron rust particles with high efficiency at a low pressure drop, by reinforcing a filter element with rigid bodies. CONSTITUTION:A perforated plate 21 of a ferromagnetic material is bent to a corrugated shape, and rigid bars 22 of a magnetic or nonmagnetic material are fixed by welding or the like to the bent parts and end parts of the plate 21.
