Title: Fast-heating hot-water storage type electric water heater
Inventor: SUZUKI TAKEFUMI
IPC: F24H1/20
Filed: 1990-08-21
Abstract: PURPOSE:To instantaneously supply hot-water with desired temperature even after the shortage of the hot-water, by a method wherein an open-or-closed valve opens when water in a heating kettle or in a hot water-guiding pipe is heated at a definite temperature, and closes when the water temperature falls at another definite temperature. CONSTITUTION:An open-or-closed valve 11 is installed on a part of a side wall 4b of a heating kettle 4, and is opened when the internal temperature in the heating kettle 4 or in a hot water-guiding pipe 10 reaches a definite temperature, and is closed when the internal temperature falls to another definite temperature and under. In this case, a thermal sensor such as a thermistor, which is installed in the heating kettle 4 or in the hot water-guiding pipe 10, is combined with an drive part such as a solenoid, which actuates the valve member of the open-or-closed valve 11. Therefore, when the thermal sensor senses that the temperature in the heating kettle 4 or in the hot water-guiding pipe 10 becomes high, the valve opens as shown with a dotted line, and when the thermal sensor senses a low temperature, the valve closes as shown with a solid line. When the valve 11 opens, the water around the heating kettle 4, i.e., at the bottom part of a water storage tank 1, flows into the heating kettle 4 and when the valve 11 closes, the water does not flow into the heating kettle.

Title: Knob for stick switch
Inventor: KUDO KAZUHIRO
IPC: G06F3/02
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To increase the operability of a stick switch and to reduce the size of the stick switch. SOLUTION: This knob 2 is provided with a recess 4 into which a tip part of a stick of a stick switch is inserted, a skirt part 6 extending with the recess 4 as a center, and a protrusion 8 formed at the center of the skirt part 6 on the opposite side of the recess 4. A top surface 8A of the protruded part 8 is formed as a recessed surface shape, and four grooves 8B are formed near intersection points between imaginary crossing lines 9 and an edge of the top surface 8A. Since the top surface 8A is formed in a recessed surface shape, the shape of the edge is sharp, and the edge of the top surface tends to get stuck on the finger cushion. The finger cushion comes in close contact with the top surface of the protrusion 8 in a recessed surface shape, and the finger cushion digs into the individual grooves 8B. This increases the operability of the knob 2 largely.  As the result, the knob 2 with a reduced height still provides an excellent operability, and has an advantage in reducing the size of a mobile portable terminal. The touch of the grooves 8b allows recognizing a tilting direction of the switch.

Title: Recording or reproducing device
Inventor: MATSUOKA HIDETOSHI
IPC: G11B15/30
Filed: 1986-09-19
Abstract: PURPOSE:To contrive miniaturization and weight reduction when the fast feed of a tape is not executed by using an outer drive means attachable and detachable to/from the titled device main body so as to drive a tape carrying means when the relative distance between a rotary drum and the tape carrying means is large. CONSTITUTION:In applying rewinding or fast feeding, the device is used in the position where the relative distance between the rotary drum 2 and the tape carrying mechanism 30 is large. In this case, since the tape carrying mechanism 30 is exposed externally from the VTR main body, mounting an adaptor 70 having an outer drive means to the mechanism allows to oppose a drive gear 72 existing on the surface of a cam lever 71 to an intermediate gear 34 of a tape winding mechanism 30. Then a cam lever motor 75 drives the cam lever gear 74 to move the cam lever 71, then the drive gear 72 meshes with the intermediate gear 34 and a pin 20p rides on a cam high part 71a. Thus, an L-shaped arm 20 is rotated clockwise against the tension of the spring 19 and a gear pulley 17 escapes from the intermediate gear 34. Then the reel motor 73 is started to drive the tape carrying mechanism 30.

Title: Infrared detector and method for correcting detection output
Inventor: YOSHIDA YUKIHIRO
IPC: G01J5/48
Filed: 1994-09-14
Abstract: PURPOSE: To correct variation in the output characteristics of an infrared detection element caused by cooling cycle. CONSTITUTION: A concave mirror 3 for bringing an infrared detector itself 2 into observing state is interposed, detachably or movably, between an optical system 1 and an infrared detector 2 comprising infrared detection elements arranged one-dimensionally or two-dimensionally. When the concave mirror 3 is interposed between the optical system 1 and the infrared detector 2, output from each infrared detection element in the infrared detector is written, as a dark current, into a memory 4 under control of a processor 6. When the concave mirror 3 is removed from between the optical system 1 and the infrared detector 2 in order to pick up an infrared image, the processor 6 subtracts the dark current component stored in the memory 4 from the output of each infrared detection element and corrects the difference using a gain data stored in a memory 5.

Title: Position detection apparatus
Inventor: ARAI MAKOTO
IPC: G01D5/26
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a position detection apparatus by which a position can be detected with high reproducibility and precisely by a method wherein a moving part is fixed to a fixation part by a deformable support member and it is coupled to an object, to be detected, by a coupling part. SOLUTION: When an object S to be detected is moved to the direction of a leaf spring 50, a coupling member 60 moves a scale 30, which has been coupled to it, to the same direction. In addition, also a mounting plate 40 to which the scale 30 has been fixed 41 is going to move in the same manner, and springs 50, 50 upper ends of which have been fixed respectively to the plate 40 are deformed elastically to the movement direction of the object S by making use of the mounting part of a lower-end base 20 as a fulcrum. As a result, the plate 40 is moved to the base 20 by a distance (d) in the same direction as the object S. Consequently, the scale 30 is moved relatively to a fixed positional-information readout means 70 so as to match the movement amount of the object S.  The means 70 detects the movement amount of the object S and its position after its movement on the basis of a periodic change in a quantity of light at a light-emitting part and a light-receiving part caused by its relative movement. Thereby, it is possible to prevent a measuring error when the object is rattled in its movement and a contact is worn, and the position can be detected with high reproducibility and precisely.

Title: Conductivity modulation type mosfet and manufacture thereof
Inventor: SAKURAI KENYA
IPC: H01L21/324
Filed: 1991-09-02
Abstract: PURPOSE:To improve the trade-off relation between the turn-off time and the forward voltage drop by forming many crystal defects only in the part near the collector layer or the buffer layer. CONSTITUTION:An n<+> buffer layer 21 and an n<-> epitaxial layer 22 are deposited on a p<+> substrate 1 to be a collector layer in that order, and a high-density oxygen 10 is diffused in the n<-> epitaxial layer 22 by heating them in an oxygen atmosphere. Then a deposit containing oxygen is formed in the n<-> epitaxial layer 22 and crystal defects 11 are produced by successive annealing at a high temperature of 900-1,000 deg.C and at a low temperature of 600-650 deg.C. Since the oxygen diffuses outside from the surface of the n<-> layer 22 at the time of the high-temperature annealing, the surface layer has no oxygen and a defect-free layer is formed. Accordingly, it becomes possible to reduce tail current at the time of turn-off and to make the increase of ON-state voltage smaller.
