Title: Gate turnoff thyristor
Inventor: NAKAMURA MASAMI
IPC: H01L29/744
Filed: 1990-03-22
Abstract: PURPOSE:To prevent an ON current from concentrating at turnoff and to improve a gate turnoff thyristor in turnoff performance without decreasing it in other characteristics by a method wherein the central part of an island- shaped first conductive layer is set lower than its peripheral part in impurity concentration. CONSTITUTION:An N2 emitter layer 2 is located closer to the center than an N1 emitter layer 1 and backward biased in impurity concentration b starting from a part a closest to a gate electrode 7, an ON current in an emitter layer is made to concentrate on the center with the elapse of a gate turnoff time, and the N2 emitter layer 2 is smaller than a part just under the N1 emitter layer 1 in injection efficiency. Therefore, a current just under the layer 2 returns to an OFF state sooner than a current just under the layer 1. Therefore, as the inner peripheral part of the layer 1 is turned in an ON state just before turnoff, the current of a thyristor of this design is smaller than that of a conventional GTO. Therefore, An ON current can be made to flow more than that in a conventional GTO in intensity by a certain degree compensated by the reduction in current density, so that a thyristor of this design can be improved in gate turnoff performance as compared with a conventional GTO.

IPC: G06F9/48
Filed: 1995-03-30
Abstract: PURPOSE: To improve the safety of an entire real-time system by checking a deadline mistake in a task switching mode based on the relation among the necessary execution time, a present execution time, a deadline time and the present time which are included in the control information (TCB). CONSTITUTION: It is checked whether a task T1 so far executed is finished or not.

A task control information setting means 5 adds the measured continuous execution time to the present execution time included in the TCB on the task T1 to set again the task control information. Then a task schedule means 2 schedules the next task to be executed. A decision means 7 decides whether the newly scheduled task T2 has a deadline mistake or not. If no deadline mistake is presumed, a task execution means 3 executes the task T2 and the switching of tasks is finished.

IPC: H01C7/04
Filed: 1990-03-23
Abstract: PURPOSE:To provide stability even in use over a wide range and to facilitate glass sealing by making a thermistor material from a sinter which contains boron carbide and further titanium carbide and/or boride as the continuity- forming substance. CONSTITUTION:In a sinter which contains boron carbide as the continuity- forming substance, sintering is conducted with an addition of 2wt.% or less of titanium carbide and/or boride to boron carbide in terms of titanium. At this time, it is preferable to add less than 1wt.% of silicon carbide to boron carbide in terms of silicon, or to add more than 0.1wt.% and less than 1wt.% of a kind or more of carbide and boride to boron oxide in terms of aluminum. A thermistor material thus prepared has low B constant and can attain B constant fixed in a wide range of temperature, e.g. room temp.-1000 deg.C. Application of such a material for the glass-sealed type thermistor element can yield a thermistor element of uniform electric resistance value.

Title: Device to control cold or hot water storage tank
Inventor: NAKAMURA TADAO
IPC: F24H1/18
Filed: 1986-04-01
Abstract: PURPOSE:To prevent midnight electric power from being used at the same time by all equipments, by detecting the remaining quantity of hot water or cold water in a storage tank nearly in the period of starting time for use of midnight electric power, and by determining the starting time of heating or cooling for each equipment by calculating the necessary time of heating or cooling by the midnight electric power, based on the detected quantity of water. CONSTITUTION:A hot-water temperature detecting part 1 detects the remaining quantity of hot water in a storage tank and the temperature in the top and the bottom parts of water. An input part 5, a memory part 6, and a timer 3 work to input or store each physical quantity related to the tank and data related to the midnight electric power time zone, that is, the outer surface area of a tank and the coefficient of over-all heat transmission of it. A tempera ture detecting part 2 receives those data and feeds them into a microcomputer 4 together with the outdoor temperature which is detected by the part 2 itself. On receiving signals of those data from the part 2, the microcomputer 4 calculates the necessary time to heat or cool the water in the storage tank. The result is subtracted from the final time of midnight electric power time zone. In such a manner, the starting time of heating or cooling can be obtained.

Title: Gain controlling and amplifying circuit
Inventor: SONEDA MITSUO
IPC: H04N5/335
Filed: 1981-05-20
Abstract: PURPOSE:To reduce the influence of disturbance noises and to improve SN sharply by directly amplifying a time-sharing current signal by a current injection type gain controlling amplifying circuit. CONSTITUTION:A time-sharing current signal iS with differential waveform from an MOS camera tube is amplified by the amplifying part of which gain is changed in accordance with the current values of controlling current sources 22, 23. A current signal iSOUT with capacitance proportional to that of the signal iS from a constant current source 24 and a collector of transistor 14 is outputted. The terminal voltage of a capacitor 16 is set to constant voltage VC by turning on a transistor 15 just before the input of the time-sharing signal iS. Thus, the terminal voltage of the capacitor 16 rises by the voltage proportional to the quantity of the current iSOUT flowing during one period on a basis of the standard voltage VC. Consequently, the current signal iS can be amplified without changing its differential waveform.

Title: Temperature controller
Inventor: UMEDA ARATA
IPC: G05D23/19
Filed: 1982-05-07
Abstract: PURPOSE:To reduce overshoot and the width of temperature ripple, by changing the width of on/off timing in response to the leading of temperature for the purpose of minute control, in a controller for fixation temperature of a copying machine. CONSTITUTION:A voltage at a point A is high when temperature is low and it is low when the temperature is high. This voltage signal is inputted to a V/F converter 2 comprising an operational amplifier 6 and an IC1 for a timer IC and the number of pulses nearly proportional to the voltage at the point A is outputted to a point B (No. 3 terminal of the IC1). Thus, when the temperature is low, the frequency of the output of the No. 3 pin of the IC1 is high, the output is inverted at an inverter 7 and inputted to a trigger terminal (No. 2 pin) of an IC2 for timer IC. When a trigger pulse interval T1 is shorter than a time constant depending on a resistor R2 and a capacitor C2, since the output of the No. 3 pin of the IC2 does not go to ''low'', a heater 5 keeps on. Conversely, when the time constant is longer, the output of the IC2 goes to ''low'' and the on-time of the heater 5 depends on the resistor R2 and the capacitor C2.
