Inventor: OKAZAKI TASUKU
IPC: H01H37/76
Filed: 1990-10-02
Abstract: PURPOSE:To obtain a temperature fuse for high temperature which works surely and precisely in a high temperature region without using fluxes which have the limit of the durability by fixing a lead pipe, which is a working piece, in a lead wire by an alloy fusible at a set temperature and also fixing the lead pipe under the pressure using a spring. CONSTITUTION:Without using fluxes, a lead pipe 3, which is a working piece, is fixed in lead wires 1, 2 by an alloy fusable at a set temperature and also the lead pipe 3 is fixed under the pressure using a spring 5.

Title: Gas laser oscillation device
Inventor: KAKIZAKI KOJI
IPC: H01S3/097
Filed: 1991-10-15
Abstract: PURPOSE:To obtain a stable laser oscillation even in the case of a number of repetitions by providing a modulation part which performs frequency modulation of at least several % from a set value for a trigger generation part. CONSTITUTION:In a trigger device 23, a trigger signal is subjected to a specified modulation by a frequency modulator 24. The frequency modulator 24 consists of a first oscillator 25 and a second oscillator 26 which inputs a sinusoidal wave to the oscillator 25. When a frequency of the first oscillator 25 is set to f, it is modulated by a second modulator 26, thus resulting in a pulse train with a maximum frequency of f1 and a minimum frequency of f2, where an amplitude of a sinusoidal wave from the second oscillator 26 is set so that, for example, (f1-f)/f and (f-f2)/f are both equal to approximately 0.05. Therefore, a thyratron 22 is in frequency-modulation operation due to a trigger pulse which is modulated, thus preventing a standing wave from being formed at a main discharge space at the time of a main discharge ignition, enabling a uniform discharge to be maintained over an entire main discharge, and preventing an output from being reduced even at a high frequency.

Title: Outflow adjustment device for electric kettle
Inventor: KOBAYASHI HIDEAKI
IPC: A47J27/21
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide an outflow of liquid straightened at all times regardless of an outflow amount by opening an inflow port in the tangent direction of a rotary flow passage and forming an outflow port below a cylindrical limit wall extended to the center upper part of the rotary flow passage in an outflow adjustment device set on the hot water discharge port of an electric kettle. SOLUTION: Hot water inside the container of the electric kettle is sent out by a liquid feeder and made to flow in from the inflow port 35 to the tangent direction of the rotary flow passage 27 and the water feeding force becomes an inflow speed to the rotary flow passage 27 as it is. At the time, the hot water inside the rotary flow passage 27 gradually slows down by its own viscosity, is pushed by the hot water successively flowing in and is gradually pushed away to a center direction while being rotated along an outer side wall 28 by centrifugal force by the fact of flowing in from the tangent direction. Then, a water level is elevated at a center part and finally, it goes over the limit wall 32 and is dripped from the outflow port 33. Thus, even when the outflow amount is changed, a fixed straightening property is maintained and it is made to flow out in a fixed direction.

Abstract: PURPOSE:To obtain inexpensively a suction valve having good valve responsiveness by forming a valve base material from a powdery needle-like crystal having heat resistance and wear resistance and packing a lightweight component having good heat radiatability into the gaps among the needle-like crystals of the valve base material. CONSTITUTION:The powdery needle-like crystal (silicon carbide) having the wear resistance and heat resistance is kneaded to a slurry by setting the quan tity of the ratio at which the volume ratio thereof with respect to the valve to be molded occupies 15-35%. The slurry is molded to the shape of the valve by pressure molding by which the valve base material is obtd. After the valve base material is dried and solidified, the lightweight component having good heat radiatability (aluminum alloy) is heated to about 700 deg.C after setting the same to the quantity of the ratio at which the volume ratio thereof with the valve occupies 85-65%. Said component is thus packed between the needle-like crystals (and on the surfaces thereof) of the valve base material. The suction valve having the small inertial mass and excellent durability and heat resistance is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To make a standard district heater unit which is not of inside and outside air two-layer flow type into the two-layer flow type by arranging a partitioning plate within the case of the heater unit, and providing a temperature control guide. SOLUTION: A partitioning plate 9 is inserted to a case 1 provided for standard district in order to make a heater unit to an inside and outside air two- layer flow type for cold district. The partitioning plate 9 is arranged in the vertical center of the case 1 to vertically partition the case 1. However, when only the partitioning plate 9 is inserted into the case 1, the vertical flow by an inner wall guide 8 is blocked by the partitioning plate 9 to deteriorate the temperature control performance. Therefore, a temperature control guide 10 is arranged on the lower stream of an air heating heat exchanger 2 and a bypass passage 3, and the wind direction carried in the case 1 is three- dimensionally changed to blow out temperature controlled air of a necessary temperature through each air outlet port 5, 6, 7. Accordingly, the cost of the heater unit for cold district can be suppressed.
