Title: Gas fan heater equipped with floor heating function
Inventor: OSAWA NORIO
IPC: F24H6/00
Filed: 1993-06-30
Abstract: PURPOSE:To restrict the temperature rise of a heat exchanger upon heating only with hot air by providing fan air control means in which the number of revolutions of an air fan is raised by a predetermined ratio with respect to the number of revolutions at ordinary time when the temperature of hot water detected by a hot water sensor exceeds a predetermined upper limit value. CONSTITUTION:When only hot air heating is performed, a burner is fired and an air fan is rotated, and simultaneously a valve 19 is closed and a circulation pump 6 is driven to circulate water in a reservoir tank 3 through a forward pipe 13, a bypass pipe 20, and a return pipe 15. A balance between heat absorption and heat radiation of the water 5 is lost and hence the temperature of hot water at an outlet of a heat exchanger 9 is rapidly raised. Thereupon, when the temperature of hot water detected by a hot water sensor 16 exceeds a predetermined upper limit, the number of revolutions of the air fan is raised by a predetermined ratio. Hereby, much room air is sucked in from a room air intake port provided on the suction side of the heat exchanger 9, so that the temperature rise of the heat exchanger 9 is restricted.

Title: Tilting hinge for office automation instrument
Inventor: OKADA SHIGERU
IPC: F16C11/10
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To attain compactness and provide high torque by providing a nonagonal hole in a rotary friction plate so as to be the same shape as a bearing part for synchronous rotation therewith. SOLUTION: A bearing part 1b is a nonagonal shape. Each rotary friction plate 2, 4, 6 has a hole of the same nonagonal shape as the bearing part 1b for synchronous rotation therewith. A device main body mounting plate 3 and a fixing friction plate 5 are formed of a circular hole for rotatably supporting the bearing part 1b. The mounting plate 3 is formed of an engaging hole 3a, to which an engaging projection 5a formed in the fixing friction plate 5 is engaged, and a rotary shaft 1 is rotated. The bearing part 1b can be made to be small diameter since the bearing part 1b is made into nonagonal shape and the rotary friction plates 2, 4, 6 synchronously rotating therewith have nonagonal holes. Moreover, high torque is provided since contact area of the rotary friction plates 2, 4 contacting to the device main body mounting plate 3 and the fixing friction plate 5 is increased.

Title: Manufacture of semiconductor device
Inventor: KODAIRA TOSHIMOTO
IPC: H01L29/78
Filed: 1980-11-18
Abstract: PURPOSE:To increase gate dielectric resistance to the same degree as the dielectic resistance of a gate oxide film, and to prevent the lowering of reliability due to fouling, etc. by etching a substrate in an extent that a thermal oxide film remains on polycrystal silicon. CONSTITUTION:The substrate 8 is thermally oxidized in an oxidizing atomosphere, and the thermal oxide film 12 is shaped onto the surface of the semiconductor substrate, from which a silicon surface is exposed, and a polycrystal  silicon surface for a tage. The whole substrate is immersed in an etching liquid  for an oxide film in fluorine, etc., and etched under a condition that only the  thermal oxide film 12 on the surface of a single crystal substrate is etched completely. The thermal oxide film 12 having approximately 1,000Angstrom  thickness  is left on the polycrystal silicon 11 because the thermal oxide film on the single  crystal silicon surface is also etched at the same etching speed. Accordingly,  holes are not formed at an end section of the polycrystal silicon 11 even when  a PSG film 13 is shaped after the whole substrate is etched, and all the gate  electrode 11 is coated with the oxide film. Consequently, the gate dielectric  resistance equalizes to the dielectric resistance of the gate oxide film, and  leakage is not generated at all.

Abstract: PURPOSE:To attain redialing at the next call even when dialing is tried after a telephone line is closed by applying redialing registration to dial information only as called party selection information among various sets of dial information. CONSTITUTION:When a trunk line 3 is a calling trunk line and dial information from a key telephone set 2 is set before a called party responds to, that is, when a CPU 107 receives the dial information from the key telephone set 2, while a trunk line incoming detection circuit 101 does not send trunk line incoming information and a trunk line response detection circuit 102 does not send called party reply information, since the dial information is the dial information to select a called party, the CPU 107 applies redial registration processing to provide the dial information into a RAM 109 through redial registration thereby completing the processing for 1 digit of the dial information. The above operations are applied to the dial information of all digits set from the key telephone set 2 and the redial registration is applied only to the dial information for called party selection.

Abstract: PROBLEM TO BE SOLVED: To uniformize the flow speed of a molten steel and to prevent overflow of inclusions by providing a pair of refractory plate-shaped transverse gates which are narrower than an inner side of a tundish and higher than the molten steel level in the regular operation at the prescribed position of the tundish. SOLUTION: A pair of transverse gates 6a, 6b are provided between the molten steel pouring position 2 and the molten steel discharging position 4 of a tundish 1 in contact with a bottom surface on the inner side of the tundish 1 so as to be opposite to side walls 1a, 1b of the tundish 1. The molten steel poured from a molten steel pouring nozzle 2 into the tundish 1 forms short pass flows 7a, 7b along the side walls 1a, 1b. The short pass flows 7a, 7b collide with the transfer gates 6a, 6b and diffused to be a uniform flow 8. The staying time of the molten steel from the transverse gates 6a, 6b to a dipping nozzle 4 is increased to improve the floating characteristic of inclusions.  It is preferable to satisfy the relationship of a/W=0.05-0.4 and D/(d+W2)=1-3.3, where, (a) is the total width of the transverse gate, W is the width of the inner side of the tundish, D is the distance between the transverse gate and the molten steel pouring position, and (d) is the molten steel level in the stable operation.

Title: Optical fiber cutter
Inventor: YOSHINUMA MIKIO
IPC: G02B6/00
Filed: 1994-06-22
Abstract: PURPOSE:To prevent excessive increasing of a speed at the time of manually advancing a cutting blade, to decrease variation in ways of giving a score and to obtain good cut surfaces by providing the above cutter with an energy absorbing means for absorbing part of the advancing energy of this cutting blade. CONSTITUTION:This cutter is provided with the energy absorbing means 70 as a damper for delaying the advancing speed by partly absorbing the advancing energy of the cutting blade 56. For example, a pneumatic cylinder is utilized for the energy absorbing means 70. Namely, a piston 74 is freely slidably and nearly airtightly fitted to a cylinder tube 72 and one end of a piston rod 76 is fixed to a block 58 of the cutting blade 56. The air in front of the piston 74 is rapidly compressed to resist the movement of the block 58 of the cutting blade 56 when this block 58 is rapidly pushed. As a result, the too fast advance of the cutting blade 56 is prevented and the good score which is a premise of good cutting is given to an optical fiber 380.

Title: Color cathode-ray tube
Inventor: YASUDA TSUKASA
IPC: H01J29/07
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To reduce the amplitude of a resonance with an external vibration by increasing the rigidity of both end parts of a shadow mask, by forming both ends of the cylindrical shadow mask corresponding to lateral ends of a screen plane into nearly circular arc shapes. SOLUTION: A shadow mask 11 is shaped into a cylindrical surface by being welded at welding points 14 to cylindrical end faces of a pair of parallel flat plates on vertical ends of a mask frame 12. Lateral ends of the pair of parallel flat plates corresponding to the vertical ends of the mask frame 12 are formed into nearly circular arc-shaped parts 13 while both ends of the shadow mask 11 corresponding to the lateral ends are formed into nearly circular arc-shaped parts 15 similar to the nearly circular arc-shaped parts 13 of the mask frame 12.  This increases the rigidity of the lateral ends of the shadow mask 11 and correspondingly decreases a resonance amplitude, and therefore, a resonance with an external vibration can be prevented to the extent that color slippage becomes insignificant without fixing the lateral ends of the shadow mask 11 or applying vibration damping bodies on the lateral ends of the shadow mask 11, and the color shift becomes imperceptible if it occurs.

Title: Testing voltage generator for gas insulating apparatus
Inventor: YAMAGIWA TOKIO
IPC: G01R31/12
Filed: 1986-07-11
Abstract: PURPOSE:To attain practical and highly reliable gas insulating test by forming a testing voltage as a waveform alternately generating at least one positive polarity voltage and one negative polarity voltage whose continuous time is shorter than the half period of a commercial frequency voltage. CONSTITUTION:An AC voltage supplied from an AC voltage source 11 in a testing voltage generator 10 is converted into a DC voltage by a rectifier 12. The DC voltage is switched through a polarity switch 13 so that positive and negative voltages are alternately applied and then the switched voltage is inputted to a shock voltage generator 14. In the generator 14, electrostatic charge charged in a capacitor is discharge to a waveform shaping circuit through a gap and a required waveform impulse voltage is generated and impressed to a gas insulating apparatus to be a sample. Even if switching impulses whose continuous time is shorter than the half period of the commercial frequency voltage are impressed several times, electrostatic force applied to a conductive foreign substance is extremely low as compared with the force impressed by the commercial frequency voltage. Thereby a highly reliable test can be attained without keeping a rigid state different from practical use.

Title: Room heating device
Inventor: SARADA TOSHIO
IPC: F24C13/00
Filed: 1985-07-23
Abstract: PURPOSE:To prevent or reduce the moisture condensate on the inner wall of a stovepipe due to the decreased temperature of combustion gas caused by heat collected by a heat exchanger, by forcibly increasing the gas temperature by opening a damper in the heat exchanger in case gas temperature adjacnet to the outlet of the heat exchanger goes lower than a specified level. CONSTITUTION:If the temperature of combustion gas 3 goes low enough to cause the moisture condensate on the stovepipe 7, the contact Ta opens to interrupt the current to the heater 14 for actuating thermal element, causing the damper 10 to open. Since the inner tube 8 is opened and the combustion gas 3 passes through the inner tube 8 without contacting the heat collecting coil 9, its heat is not taken away and the gas temperature ruduction is small. As the gas temperature rises, it is again detected by the temperature detecting element 15 to close its contact Ta, and therefore, the power supply to the heater 14 is resumed to again close the damper 10. During a period in which the damper 10 opens and closes, however, high-temperature gas is supplied to the stovepipe 7 to prevent the moisture condensate.

CONSTITUTION:In the case of a high moisture content paper 4 which can not be controlled by correction control that electrostatic charging, copying and separating conditions as the image forming conditions of a photosensitive body 1 are varied, resistance data detected by a paper resistance detecting device provided in a paper feeding device 5 is judged. Based on a copying start key signal, a carrying path for the paper 4 is set in a both-side copying mode and the paper is dried by passing through the fixing device 9 before forming the image. The paper is carried to and stopped at a resist roller 6 by a both-side reverse feeding device 20, and the stage is shifted to an ordinary copying stage. In timing with the leading edge of an image on the photosensitive body, the resist roller 6 is actuated and the image is formed on the paper 4.
