Abstract: PURPOSE:To readily obtain the title single crystal useful as a superconducting substance at a relatively low temperature, by compression forming a raw material powder of the title compound and excess CuO under specific conditions, calcining, quenching and heat-treating the resultant compact. CONSTITUTION:A raw material powder (e.g., Y2O3, BaCO3 or CuO) is mixed with excess CuO so as to provide a composition of 50-10/50-90 molar ratio of the compound expressed by the formula (R is rare earth element except Sc, Ce, Pr, Pm and Tb; delta<0.6) to excess CuO and the resultant mixture is pulverized and press formed to afford a compression compact, which is then heated under conditions so as to form hermetically sealed cavities therein, e.g., the compact is initially heated at 750-850 deg.C and kept at the temperature for 20-60min to decompose BaCO3. The resultant compact is subsequently quickly heated at >=40 deg.C/min to 950-1,140 deg.C and then kept at 1,100-1,300 deg.C for >=30min to form a calcined compact having the above-mentioned cavities. The obtained compact is subsequently quenched to <=500 deg.C, reheated to 920-1,050 deg.C and kept at the same temperature for a long period (e.g., >=3 days) to grow a crystal.

Title: Rice boiler
Inventor: KAWAKAMI SHINICHIRO
IPC: A47J27/00
Filed: 1991-03-04
Abstract: PURPOSE:To prevent a lid body from rising to an abnormally high temperature without any substantial insulation measures, and minimize wasteful power consumption due to the operation of a lid heater. CONSTITUTION:Measurements are taken about time (t) for a temperature sensor to rise up to a value of between 70 deg.C and 80 deg.C in a rice boiling operation. When the time (t) is equal to or longer than a reference time t0, boiling capacity is judged to be large. When the time (t) is shorter than t0, the capacity is judged to be small. In the case of the large capacity, when the temperature sensor detects boiling, a rice boiler heater is kept turned on for 100 seconds and off for 20 seconds repeatedly, and continuous power supply to a lid heater starts. This continuous power supply continues, even during a later steaming process. In the case of the small capacity, when the temperature sensor detects boiling, the rice boiler heater is alternately kept turned on and off for 60 seconds repeatedly. When a steaming process starts later, the continuous power supply to the lid heater starts.

Abstract: PURPOSE:To establish a measure for environmental contamination by preparing a mercury alloy for a fluorescent lamp from mercury and zinc or an alloy containing zinc, making the alloy phase eutectic or peritectic, and giving the alloy a melting point over 200 deg.C and a pellet shape having a diameter below 3mm. CONSTITUTION:82-43wt.% mercury and 18-57wt.% zinc are mixed together, wherein the mol content of zinc is made between 40-80%. The resultant is mixed, heated, melted, stirred uniformly, passed through a heated nozzle having an inside diameter of 1-3mm, and cut into lengths 1-2mm so that pellets of 1-3mm in diameter are produced. The range 40-80% of the mol content of zinc yields a mol content of mercury between 60-20%. Thereby little return of mercury is generated in the alloy, and characteristics identical to fluid mercury are provided. The value of the vapor pressure does not vary substantially in the range where the zinc has a mol content between 30-90% being in the eutectic or peritectic phase.

IPC: H05K3/42
Filed: 1989-02-20
Abstract: PURPOSE:To contrive the improvement of the productivity of a printed circuit board by a method wherein a resist film on the circuit board is exposed through a photomask, with which a part to be formed with conductive wires is interrupted from exposure light, and scattered light is irradiated only on a non- through hole part through a photo-mask which transmits light.

Then, an active energy line in the form of scattered light is irradiated only on the non-through hole part through a photomask, through which the active energy line is passed, and the resist film irradiated with the active line is developed. The exposed copper-plated part is etched away and moreover, the resist film on the part to be formed with the conductive wires is removed. In such a way, as two times of exposure processes are performed, the productivity of the circuit board is improved.

Filed: 1988-02-19
Abstract: PURPOSE:To reduce losses in pressure, noise, and vibration caused by eddies by providing an arc-shaped guide plate at the bottom of a duct and a square tapering hopper-shaped outlet for the fan so as to guide a current of air to change its direction smoothly and spread the air discharged from the fan. CONSTITUTION:A guide plate 8 in the shape of an arc is attached to the bottom of a duct 2. A square tapering outlet 7 in the shape of a hopper connects the discharge opening of a fan 3 with the underside of a filter 5. The air circulated from rooms is orientated toward the fan 3 by the guide plate 8 provided in the duct 2 and led through an opening 4 to the fan 3. The current discharged from the fan 3 is decelerated smoothly with eddies reduced as it passes through the hopper-shaped outlet 7 to the filter 5. As a result, the losses in pressure, noise, and vibration, all caused by eddies, are reduced and the motive power required to drive the fan is also reduced. The hopper-shaped outlet 7 and the casing 1 jointly serve to shut off the noise from the fan 3, so that the noise coming out of the casing 1 is reduced.

A plane where the bag separator is abutted against the positive plate is provided with a plurality of rib projections 1 where a space of portions in parallel with a vertical direction of the positive plate and abutted against the end part of the positive plate is made narrower than that of other portions. With such an arrangement as above, even in the case that a frame grid of the positive plate is curved by overcharging or the like under a high temperature, a contacted location of the separator with the positive plate is limited to the rib-like projections, so that deterioration of the ground part of the separator is restricted.  In addition, an installing space of the rib-like projection at a part abutting against the end part of the positive plate is preferably 50% or less of a thickness of the positive plate.

Title: Piezoelectric substrate
Inventor: YOSHINAGA TAKASHI
IPC: H03H9/13
Filed: 1991-03-05
Abstract: PURPOSE:To prevent a disconnection and to improve the reliability by adopting a laminate plate of a specific metal for an electrode film. CONSTITUTION:An Ni layer 16 is formed on the piezoelectric substrate by sputtering or the like except ends of both front and rear sides of a base substrate 12 made of ceramic or the like, an Ag layer 18 is formed on the layer 16 by sputtering to form an electrode film 14. Since the layer 16 is hard and has high stiffness, even when dust or dirt is deposited on the film 14 and an external stress is exerted thereto, an outer flaw resulting in a broken layer is not caused. Moreover, even when an external stress is exerted to the piezoelectric substrate itself, the layer 14 is neither broken nor cracked. The specific resistance of the layer 16 is increased and a defect in the deterioration in the solderability is compensated by forming the layer 18 on the layer 16. Thus, the disconnection is prevented and the reliability is improved.
