Title: Control device for electric water heater
Inventor: OSHIO SEIJI
IPC: F24H1/18
Filed: 1987-09-28
Abstract: PURPOSE:To prevent temperature within a hot water tank from being excessively lowered by a method wherein a signal from a hot water temperature sensor is compared with a boiling temperature set signal and a differential value of an energization of an electric heater is decreased when the boiling temperature set is low. CONSTITUTION:When a hot water temperature sensor 3a detects that temperature within a hot water tank is low, an output from a comparator 13 shows an 'L' voltage, transistors 18a and 15 are turned ON, a feed-back resistor 14 is inserted in parallel with a reference resistor 25. A differential value until the reference voltage is decreased and energization for an electric heater 2a is stopped is generated. A transistor 21a is also turned ON to drive a coil 22a, energization of a heater 2a is started and when a hot water temperature sensor 3a detects its boiling temperature, output from the comparator 13 shows 'H' voltage, a feed-back resistor 14 is turned off, the reference voltage becomes high and then energization of the heater 2a is terminated. When a set boiling temperature is low, the reference voltage is low, so that even if the feed-back resistor 14 is connected in parallel, the voltage is less decreased and the differential value is decreased.

Title: Extra high pressure mercury discharge lamp
Inventor: YAMAZAKI SHIGERU
IPC: H01J61/20
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To prolong the lifetime, while preventing the generation of a leak and a burst of an arc tube due to the generation of crack at the time of lighting and extinguishing a lamp by forming a high-melting point metal current lead to be bonded to an electrode, so that it is not exposed to the inside of an expansion part of the arc tube except for a bonding surface thereof. SOLUTION: Both the tube ends of a translucent ceramic arc tube 1 are formed of a narrow diameter part 2 which is narrower than the diameter of a swelled part provided at a central part of the arc tube 1, and a high-melting point metal current lead 4 made of niobium having a coefficient of thermal expansion close to that of a ceramic with a tungsten electrode 3 welded to one end thereof is inserted along an axis of the narrow diameter part 2 of the translucent ceramic arc tube. The metal current lead 4 and the narrow diameter part 2 are sealed airtightly by an alumina- calcia base sealant 5. Since the metal current lead 4 bonded to the electrode 3 is not exposed to the inside of the ends of the swelled part of the arc tube except for the bonding surface thereof, the deformation of the metal current lead 4 due to the internal pressure at the time of lighting and pressure change at the time of lighting and extinguishing a lamp and generation of leakage due to the deformation can be avoided.

Title: Electrtomagnetic fuel injection valve
Inventor: TERAKADO KAZUYOSHI
IPC: F02M51/06
Filed: 1987-09-30
Abstract: PURPOSE:To enhance the responsiveness of the opening/closing operation of an injection valve so as to improve the accuracy of fuel injection quantity by forming, with a non-magnetic material, at least either member of a stopper and a valve seat for restricting the stroke of movable elements. CONSTITUTION:A valve guide 9 including a valve seat 9a and a stopper 11 are formed with a titanium alloy which is a non-magnetic material. In this way, the formation with the non-magnetic material makes it possible to form a magnetic circuit with a normal yoke 3, a fixed core 4 and a plunger 5, and to extremely reduce any magnetic leak of the stopper 11 and the valve guide 9. As a result, the magnetism attracting and returning operation of movable elements 5-7 speeds up so as to shorten a period required for the rising and stopping operation of fuel injection, thereby remarkably enhancing fuel injection quantity performance. In addition, the adhesion of iron impurity to the stopper 11 and the valve seat 9a during fuel injection is prevented, thereby improving the accuracy of fuel injection quantity.

IPC: G11B5/09
Filed: 1983-12-26
Abstract: PURPOSE:To eliminate undershoot by giving a delay to a reproducing signal to a position where undershoot exists, attenuating the signal to an amplitude corresponding to the level of the undershoot and overlapping the result to the original reproducing signal. CONSTITUTION:A delay time corresponding to the time difference between a position 16 where undershoot is larger and a position 17 where the amplitude of a reproduced waveform is maximum is set to a delay element 10 and a delay time corresponding to a time difference between the position 17 and a position 18 is set to a delay element 11. Then the amplitude of a signal 19 is set by a coefficient element 12 so that the level of the signal 19 corresponds to the amplitude of the undershoot at the position 16. A coefficient element 14 is set similarly. Thus, a reproduced waveform 22 without undershoot is obtained by superimposing output signals 19-21 of each tap. Then the undershoot is eliminated without spreading the width of the reproduced waveform and the width of the reproduced waveform is narrowered, then it is possible to compensate the capability deficiency of medium recording by making the head pole thick.
