Title: Current-limiting element using oxide superconductor and its manufacturing method
Inventor: MORITA MITSURU
IPC: C01G1/00
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To form the current-limiting element of a thin film that is reliable against melting process and where quench is propagated uniformly and speedily, by using a superconductive bulk body with a high critical current density where RE2 BaCuO5 is finely dispersed into REBa2 Cu3 O7-x . SOLUTION: A superconductive bulk material in single crystal shape with 46mm diameter and 15mm height where RE2 BaCuO5 is finely dispersed into REBa2 Cu3 O7-x is sliced into a piece of 1mm thick, and further cutting machining is performed for creating a superconductor with a current path sectional area of 2mm<2> . Then, silver paste is applied on the surface, temperature is temporarily increased to 900 deg.C in oxygen air flow, and then this condition is maintained for 10 minutes. Then, temperature is decreased to 600 deg.C in two hours, and further temperature is decreased to a room temperature in 20 hours. Then, after a copper lead is connected to the electrode part at both terminals by soldering, it is cooled in liquid nitrogen, thus directly energizing the critical current at 500A and energizing a current with a momentary value of a maximum of 1,500A.  Hence, a current-limiting element for limiting current to 900A is obtained without melting.

IPC: B60P3/00
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a favourable acoustic property and to form a large working space inside by making a case body free to displace so that a surface on the side to face against the working space provided inside is the case body to be opened and a blocked surface facing against an opened surface is projected from a wall surface on the side of a vehicle. SOLUTION: A blocked surface is constituted of an outer plate 3 which is a part of a wall surface on the side of a vehicle so as to make depth of a case body 1 as large as possible. The case body 1 is made to project to a side where a boarding door 4 is provided. As width dimensions of the boarding door 4 and projection quantity of the case body 1 are made roughly same as each other, and accordingly, when it is a place large enough to open and close the boarding door 4, there occurs no nonconformity that the case body 1 cannot be projected. Consequently, especially in the case of using it as a voice repeater car, it is possible to easily form a working space in size sufficient for mixing work inside and having a favourable acoustic property.

Title: Constant power circuit
Inventor: IZUKAWA KAZUHIRO
IPC: G05F1/56
Filed: 1988-11-28
Abstract: PURPOSE:To reduce the switching loss and to realize a constant power circuit having high efficiency by adding a filter circuit to a feedback circuit to produce a time delay and to increase the ON/OFF period of a MOS FET. CONSTITUTION:A reset IC 8 rises up with a time constant which is decided by the battery voltage Vbat 2, a resistance 9, and a capacitor 10. When the input voltage Vin of the IC 8 exceeds the voltage Vin 1, the output Vout of the IC 8 outputs the high output voltage. Thus a transistor TR 6 is turned on. Then the gate voltage VG of an FET 2 is equal to about 0V and the FET 2 is cut off. Therefore the voltage VG is reduced down to 0V by the load of the voltage Vbat 2 and the time constant of the voltage Vin is reduced. When the Vin is reduced less than the voltage Vin 2, the output of the IC 8 is equal to 0V and the TR 6 is cut off. Then the voltage VG is set at the same level as the output VH of a boosting circuit 1. Thus the FET 2 is turned on.

Title: Heating method for bath room and the like
Inventor: KATO SHOZO
IPC: F24D15/00
Filed: 1989-11-20
Abstract: PURPOSE:To eliminate two kinds of troublesome operation, one being heating and the other being bathing preparation for a bath tub, and to prevent a switch from being left turned OFF by a method wherein a bath tub control device is combined with a heating control device for a bath room, and based on a bath tub control signal for bath, heating operation for a bath room is effected. CONSTITUTION:A signal (bath tub control signal) by means of which a bath tub 1 is filled with hot water for preparation for a bath and water in the bath tub 1 is heated is controlled. Based on the signal, heating for a dressing room 9 and s bath room 8 is started. Heating for the bath room is not effected such that the bath room is brought into a comfortable state simultaneously with the starting of heating, and it takes a time of approximate fifteen minutes to bring the interior of the bath room into a comfortable state. Further, it generally takes approximate fifteen minutes to fill the bath tub 1 with hot water. Thus, heating operation may be approximately simultaneously started. When the bath tub 1 is already filled with water, it takes a long bath tub preparation time depending upon the temperature of hot water in the bath tub. Thus, in this case, simultaneous starting is wasteful. Since a time in which water is boiled up to a proper temperature depends upon a hot water temperature, the time can be assumed from a hot water temperature, and from a calculating time, a lag of a heating starting time is calculated and controlled.

Title: Heating cooking utensil
Inventor: NISHIMURA NOBUICHI
IPC: F24C7/02
Filed: 1988-11-29
Abstract: PURPOSE:To make it possible to heat and finish properly in consideration of the weight of a container to be used by comparing comparison data equivalent to detected weight by a weight sensor with the change in the output of a gas sensor under actual cooking, and compensating execution time for a finishing heating process based on the comparison result. CONSTITUTION:Unheated food 12 is heated by high frequency when a magnetron 14 starts its operation. Then, the output of a gas sensor 23 judges points of time Ta, and Tb when a peak value Vsmax drops to alphaVsmax and judges again the lapse of time from the commencement of heating T0 and the points of time Ta and Tb and moves to a finish heating process. In the previous stage, a weight sensor 18 detects the weight of uncooked food 12, and reads compari son data td equivalent to the detected weight from a memory section 25. After check time ta, and tb are judged, the check time ta and tb are immediately compared with the comparison data td. When it is judged as ta<td, the genera tion period of gas is earlier than a maker-assumed time D, which clearly indicates that the net weight of food 12a is smaller than the estimated value (the weight of a container 12b is larger than estimated).

Filed: 1993-12-01
Abstract: PURPOSE:To obtain a good driving performance by providing a driving voltage forming circuit where the driving voltage is set lower than the power supply voltage or controlled depending on the value of power supply voltage thereby supplying a stabilized driving voltage. CONSTITUTION:An ultrasonic motor is set to exhibit a desired driving performance when the output driving voltage from switching circuits 4, 5 equals to VM and a driving voltage forming circuit 1 generates a driving voltage VM equal to the power supply voltage Vo under control of a microcomputor 10. In this regard, the switching circuits 4, 5 convert the driving voltage VM into an alternating voltage which is boosted through boost coils 6, 7 and fed to moving electrodes A, B thus rotating the ultrasonic motor with a desired driving performance. Since the driving voltage VM is applied to the motor itself even upon fluctuation of the power supply voltage Vo, the motor can be driven with a desired driving performance.
