Abstract: PURPOSE:To increase the feeling of safety of a user in a unit for displaying a plurality of combustion volumes in a petroleum fan heater or the like by a method wherein when the combustion volume varies by more than two-steps, the combustion volume is varied is sequence step by step every time the desired time is elapsed. CONSTITUTION:When a room temperature 2, a set temperature 3 and a heater temperature 4 are inputted to a micro-processor 1, a difference D between the set temperature 3 and the room temperature 2 is calculated to determine a combustion volume A, a frequency signal is outputted from an output port 7 and at the same time a fan motor signal having a pulse width corresponding to the combustion volume A is outputted from an output port 8, and both an electromagnetic pump 12 and a fan motor 17 are driven correspondingly to the combustion volume A. Simultaneously, light emitting diodes 61-65 of a display unit 6 are lit in correspondence with the combustion volume A. At this time, when more than two steps vary, the display lamps are lit in sequence step-by-step every time an internal timer is elapsed. With this arrangement, a feeling of threat of a user is prevented.

Title: Driving circuit for brushless dc motor
Inventor: HANAJIMA MITSURU
IPC: H02P6/06
Filed: 1979-02-15
Abstract: PURPOSE: To reduce the adverse affection of an offset voltage to a brushless DC motor due to the voltage variations of a power supply by inserting a capacitor in series with a signal line from the input side of an amplifier for amplifying the output signal of a position detector for the motor to a stator coil of the motor.  
     CONSTITUTION: An input voltage Vi to an amplifier 8 is obtained from a f-V converter 18 receiving an input of the terminal voltage frequency of the stator coil of a brushless DC motor. The higher the frequency of the stator coil of the motor becomes, the lower the DC voltage Vi becomes. Thus, the motor can be controlled at constant speed through this feedback control loop. When starting the motor, a zener diode 19 is conducted to conduct transistors 17 so as to short-circuit capacitors 11 and to turn the zener diode 19 and the transistors 17 off in the vicinity of the ordinary speed. Since the capacitors 11 are thus connected, the offset voltages of Hall elements H 1 , H 2  and the amplifiers 12 are not amplified by the amplifiers 12.

Abstract: PROBLEM TO BE SOLVED: To improve the performance index by sufficiently removing oxygen in a sintering process without using reducing gas by providing the removing process, wherein the oxygen, which is bonded to thermoelectric-conversion raw-material powder, or the oxygen between the powders is removed in the sintering process. SOLUTION: Carbon powder 2 dispersed in a molded body 4 reacts with the oxygen in the oxide body of BiTe-based compound in the vicinity, that is to say, the oxygen bonded to thermoelectric-conversion raw-material powder 1, and the oxygen present in the gap between the thermoelectric-conversion raw-material powders 1, respectively. The oxygen is removed as the carbon dioxide. That is to say, the carbon powder 2 reacts with the oxygen in the vicinity at first, and the carbon monoxide is generated. The carbon monoxide is dispersed and penetrated into the molded body 4 and further reacts with the oxygen, and the carbon dioxide is generated. The oxygen, which is bonded to the thermoelectric-conversion raw-material powder 1, or the oxygen in the molded body 4, is removed.  Furthermore, the carbon powder 2, which has reacted with the oxygen, becomes the carbon dioxide gas, and the gap is formed at this part. Therefore, the thermal conductivity of the molded body 4 becomes low.

Abstract: PURPOSE:To prevent generation of an auto-doping as well s to form a film by thermal oxida tion having few crystal defects by a method wherein a process in which a semiconductor is heated up to the first temperature and a semiconductor substrate is maintained at the first temperature for the first prescribed period and another process, in which the temperature of the semiconductor substrate is lowered to the second temperature and it is maintained at the second temperature for the second prescribed period which is longer than the first prescribed period, are included in the manufacturing processes of the titled thermally oxided film. CONSTITUTION:A semiconductor substrate whereon a silicon nitride film is coated is inserted into a heating furnace, and after the heating furnace has been maintained at 850 deg.C-950 deg.C for the prescribed period of time, the furnace is heated up again. When the furnace reaches 1,200 deg.C of the first temperature, this temperature is maintained for the first prescribed period of time D, and then the temperature is brought down. When the temperature of the furnace reaches about 1,000 deg.C of the second temperature, this state is maintained for the second prescribed period of time E, and the increase in thickness of an oxide film is contrived. As the semiconductor substrate is maintained at the high temperature of about 1,200 deg.C for the first prescribed period, the internal stress caused by the difference in thermal expansion coefficient of the silicon nitride film and a silicon dioxide film can be removed, and the generation of crystal defects can also be reduced sharply.
