Title: Electric hot water supply heater
Inventor: MIYANOHARA TAKETO
IPC: F24H1/18
Filed: 1990-11-14
Abstract: PURPOSE:To heat lower temperature water from a hot water storage tank to the boiling temperature in a very short time and supply when the hot water runs out in the tank by driving a plasma heater when the water temperature in the hot water storage tank drops below the boiling temperature during hot water supply. CONSTITUTION:When water temperature in a hot water storage tank 1 drops below the boiling temperature for some reason in a midnight power rate time, an electric heater 2 is driven again so as to keep the water temperature in the tank at the boiling temperature. When a detected temperature of a temperature sensor 4 drops below the boiling temperature during hot water supply time, or more specifically, when the hot water runs out, a plasma heater alone 3 is driven this time. As a result, lower temperature water which flow out from a hot water outlet 1b is heated to the boiling temperature by the plasma heater 3 instantly. After heated up, the hot water is introduced into a hot water supply outlet 12 by way of a hot water supply pipe 6. This construction makes it possible to supply hot water in a similar manner of an instantaneous water heater.

IPC: H02K7/09
Filed: 1990-11-15
Abstract: PURPOSE: To prevent the heat of a regenerative resistor and at the same time surely supply electric power to a magnetic bearing by supplying electric power to the magnetic bearing from the regenerative electric power of an electric motor when a main electric power source is brought into trouble. CONSTITUTION: AC source power is made into a DC by a rectifier 8, and the DC is made into an AC by an AC converter 4 to supply the AC to the stator 2 of an electric motor. A magnetic bearing 3 is fed from the AC power source through an electric power source circuit 11 and a control circuit 12. When a main power source fails, a switch 15 is closed, a pump 1 is operated as a synchronous generator to supply a direct current to a line 5 and to supply electric power to the electric power source 11 through an auxiliary electric power circuit 14. Therefore, the feeding into the magnetic bearing 3 is ensured. When rotation is lowered and consequently the voltage of the auxiliary electric power source circuit is lowered, an emergency switch 18 is closed to feed the electric power of an emergency battery 13 to the magnetic bearing 3.

Abstract: PROBLEM TO BE SOLVED: To eject a foreign material inserted from the card slot of an IC card processor to the outside by providing a foreign material discharge port passing through the outside from a deep wall on the extension of a rail plate. SOLUTION: A card housing part 80 for housing and supporting the IC card inserted from a card slot 23 is composed of a substrate 61 of a frame 60, both side walls 71 and 72 of a lower cover 70, deep wall 73, rail plate 74 and lower plate 75.

Abstract: PROBLEM TO BE SOLVED: To improve Hall effect, and reduce the influence of a magnetic field upon other circuits when a Hall element is formed in a chip together with other necessary circuits, by converging a magnetic field applied from the outside, on the surface of a semiconductor active layer. SOLUTION: A thin metal film 2 having magnetic field converging effect is formed as a magnetic field converging means for converging a magnetic field 7 from a magnetic field generating source, on a semiconductor active layer (a surface rectangular to the direction of a magnetic field applied to a Hall element 1) of the Hall element 1. An evaporation film of Ni-Zn is used as the thin metal film 2. By virtue of the film 2, the magnetic field 7 from the magnetic field generating source is converged on the surface of the semiconductor active layer and passes it. Thereby the magnetic flux density in the direction vertical to the semiconductor active layer surface is increased, and Lorenz force acts efficiently, so that Hall effect of high efficiency can be obtained.  The thin metal films 2 having magnetic field converging effect may be formed on the surface of the semiconductor active layer and the back of the element.

Abstract: PURPOSE:To enable adjustment of a gap between a print head and a platen by a simple structure, by changing the angle of inclination of a cover to a base in a closed state of the cover. CONSTITUTION:In the condition that a cover 20 is locked in a closed state, a gap between a print head 3 and a platen 4 is adjusted.

Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To enable highly sensitive detection by arranging a gate circuit or the like to make an output signal of a fluorescence detection sensor pass synchronizing with the emission of a flash lamp. SOLUTION: A timing signal generated in a timing signal generation circuit is sent to a trigger signal generation circuit while a trigger signal generated is sent to a light emitting circuit for emission of a flash lamp. On the other hand, the timing signal is sent to a gate signal generation circuit to actuate a gate signal circuit. The flash lamp emits light delayed by several μsec. from the generation of the trigger signal with the operation of the light emitting circuit to irradiate a sample within a measuring cell and a fluorescence pulse from a fluorescent substance in the sample is received by a fluorescence detection sensor to be outputted as electric pulse. An output from the sensor is sent to an integration circuit passing through the gate circuit only during the opening of the gate circuit.  The gate circuit passes an output signal of a fluorescence detection sensor only for the time when the gate signal from the gate signal generation circuit is being inputted.

Abstract: PURPOSE:To decrease the number of parts of an optical system by obtaining a focus error signal by the difference in the output of a photodetector disposed optically in such a manner that output light is imaged to the position deviated by a slight distance along the line orthogonal with a parting line. CONSTITUTION:The laser beam reflected from a memory medium 8 and a guide track 9 is reflected on the slope of a molded prism 13 and arrives on the photodetector 12 through a spot lens 10 and an analyzer 11. The photodetector 12 is the quadrisected photodetectors consisting of 1st to 4th elements (a) to (d) which are so disposed that the parting center of the photodetector 12 deviate by a slight distance delta in the direction of the one parting line with respect to the optical axis center of the reflected laser beam. The focus error signal is amplified and compensated according to the kinetic characteristics thereof by a driving device of a condenser lens 6. This signal is fed back to control a tracing device in such a manner that the irradiation point exactly traces on the guide track 9. The optical system is simplified by using the molded prism 13 having the function of beam forming and beam splitter in combination in this way.
