Abstract: PROBLEM TO BE SOLVED: To enable the accurate detection of humidity by providing an impressed electric current from an amplifying circuit for a heating resistor formed on a substrate together with an electrode for detecting temperatures, and heating the whole of a temperature detecting element even when water drops adhere to the surface of a humidity sensing ceramic. SOLUTION: A measuring element 1 for measuring temperatures is provided with a heating resistor 5 as a heater for heating the element 1 to improve the accuracy and durability of the element 1.

Inventor: KIM YOU HO
IPC: H01C7/02
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a circuit for preventing rush currents which are produced when alternating-current power is supplied intermittently to a load, and its application to a microwave oven. SOLUTION: A PTC(positive characteristic) thermistor 12, which limits the magnitude of current output to a load to a specified value or below due to its temperature- resistance characteristic even if a rush current exceeding the specified value is applied, is placed between a power supply and a load and is connected with a switch 10 in parallel. After a specified delay time has passed from the time at which an alternating- current signal is input to a full-wave rectifier, a direct-current relay 14 is excited by a direct-current signal from the full-wave rectifier and provides a switch 10 with a signal to turn on the switch. The switch turned on is provided to the bypass circuit of the PTC thermistor 12.  During the period of the specified delay time from the time of input of an alternating-current signal to the full-wave rectifier, the alternating- signal is supplied to the load through the PTC thermistor 12. After the delay time has passed, the alternating-current signal is supplied to the load through the switch. Thus rush currents which are produced during intermittent power supply are interrupted effectively.

Abstract: PURPOSE:To efficiently produce H2 being a final product at low cost by inserting the decomposition reaction pipe of ammonia into the oxidative fluidized bed of a reactor main body so that the end parts of the inlet and outlet are led out to the outsides respectively. CONSTITUTION:A plurality of decomposition reaction pipe groups 2 are inserted into an angular-type or round-type catalytic oxidative fluidized bed 1 and allow to be always held in such a state that these are brought into contact with the inside of the fluidized bed 1.

CONSTITUTION:After an Si3N4 film 4 amounting to about 5000Angstrom is formed on the rear of an Si single crystal substrate 1 with a plasma CVD process, an intermediate layer 3 consisting of a low temperature growth layer at a growth temperature of the order of 400 deg.C as well as of a high temperature growth layer at a growth temperature of the order of 700 deg.C and amounting to about 1.5mum is formed with an organic metal vapor phase epitaxy(OMVPE) process on the Si single crystal substrate 1. After that, its layer is treated with heat at a temperature 800 deg.C in an atmosphere of arsine (AsH3) for 1-10 hours. Further, a GaAs single crystal layer 2 amounting to 1mum is formed at a temperature 700 deg.C. Dislocation density in the GaAs single crystal at a semiconductor substrate which is treated with heat for 1-10 hours is about 10<6>cm<-2> and 10<5>cm<-2> respectively. In this way, heat treatment time is lessened by approximately 1/10 or less in comparison with its time required by conventional processes or dislocation density decreases with a high reduction of more than one digit.
