Title: Supercharging pressure control device for internal combustion engine
Inventor: YOSHIOKA MAMORU
IPC: F02B33/00
Filed: 1986-01-31
Abstract: PURPOSE:To harmonize both demands for prevention of the occurrence of a switching shock and improvement of acceleration performance with each other according to a demand occasioned by a transmission ratio state, by a method wherein, during the starting of supercharging, the rising state of a supercharger is controlled depending upon an acceleration state and a transmission ratio. CONSTITUTION:When an acceleration state, e.g., a throttle opening speed, detected by an acceleration state detecting means C, exceeds a set value, rapid closing of, for example, a bypass control valve causes control of a supercharging state. A set value is varied with a transmission ratio detected by a transmission ratio detecting means E. During low gear running, a set value is increased to decrease production of an acceleration shock, and during high gear running, a set value is decreased to improve a supercharging response.

Title: Apparatus for preparing thermal head
Inventor: SAWAE TETSUNORI
IPC: H01L49/00
Filed: 1985-01-30
Abstract: PURPOSE:To effectively lower the resistance value of a heat generating resistor, by mounting a pulse generation circuit and a resistance meter and prohibiting the generation of a voltage pulse within a definite time after a change-over connection circuit was connected to a resistance meter after a voltage pulse was applied to a heat generating resistor. CONSTITUTION:When a voltage application start signal START is received from a calculation part 12, a pulse generation circuit 10 returns an ENABLE prohibiting signal to the calculation part 12. After a definite time T is elapsed after the START signal was applied, the pulse generation circuit 10 applies a voltage pulse to a heat generating registor. When time T2 was elapsed after the application of said pulse was completed, a switch 9 is changed over to the side of a resistance meter 11. After time T3 was further elapsed, an ENABLE prohibiting signal is released to enable the next application of voltage. The measured result of the resistance value is sent to the calculation part 12 during the time T3 and the comparison of the resistance value and the setting of the peak value of the next voltage pulse are performed by CPU14. Therefore, the charring of the switch 9 and a relay network 8 is prevented and the resistance value can be lowered effectively.

Title: Temperature control method for heater
Inventor: FURUICHI MASAYOSHI
IPC: G05D23/24
Filed: 1981-02-09
Abstract: PURPOSE:To secure a fixing state stably by measuring the temperature of a heating body, and its ambient temperature and humidity, and obtaining a reference value for control over the temperature of the heating body by finding a converted temperature value which corresponds to the humidity. CONSTITUTION:The temperature and ambient temperature of the heating body 4 of the oven type heat fixing device of a copying machine are measured by heat- senting elements 10 and 12 respectively and a signal A which corresponds to the sum of the both is applied to the terminals 18a and 18b a temperature control circuit 18. A signal B which corresponds to the ambient humidity measured by a humidity sensing element 20 is applied to the terminals 18c and 18d of the circuit 18. The circuit 18 finds a converted temperature value which corresponds to the value of the signal B and adds the converted temperature value to reference value for control over the temperature of the heating body 4 to a prescribed value to obtain a new reference value. So that the signal A has the new reference value, a pulse signal is outputted to an amplifier 22 to control the heating body 4, thereby adjusting the sum of the temperature of the heating body and its ambient temperature to the best temperature value for the fixing of copying paper by the electronic copying machine.

Title: Piezoelectric driving apparatus
Inventor: TAKADA TAKASHI
IPC: H01L41/08
Filed: 1988-01-26
Abstract: PURPOSE:To obtain a bistable type piezoelectric driving apparatus characterized by long- distance operation and low power consumption, by providing attracting members whose attraction is caused by magnetism at both ends of the back and forth strokes of a movable member, and providing a pair of piezoelectric elements for moving the movable element to the other side with a shocking force against the magnetic attracting force. CONSTITUTION:A pair of laminated piezoelectric elements 1A and 1B are arranged so as to face each other. A movable member 3 is supported with a guide member along the central axis of said elements. Two magnetic plates 4A and 4B are fixed to the movable member 3 at a specified space. A permanent magnet 5 is fixed to a fixed base 2 between the plates. When the magnetic plate 4B is attracted with the magnet 5, the movable member 3 is brought into contact with the laminated piezoelectric element 1A. A slight gap is yielded between the magnet 5 and the magnetic plate 4B. When a voltage is applied to the piezoelectric element 1A instantaneously, the piezoelectric element 1A is elongated. The movable member 3 is moved to the side of the laminated piezoelectric element 1B by the shocking force. The magnetic plate 4A is attracted to the magnet 5. The movable member 3 is brought into contact with the piezoelectric element 1B and stopped. When a voltage is applied to the piezoelectric element 1B, the movable member 3 is returned to the original position. Thus, long distance movement can be performed without decreasing efficiency.

Title: Heater controlling device of oxygen concentration sensor for internal combustion engine
Inventor: TSUKAMOTO KEISUKE
IPC: G01N27/409
Filed: 1990-01-30
Abstract: PURPOSE:To shorten the time from the start of engine to the actuation of a lean sensor by detecting the resistance value of a heater in a specified period after the transition into a low-load operation from the high load of the engine, and making the specified period before the completion of warm-up shorter than the period after the completion of warm-up. CONSTITUTION:Basic electric power Po (W) which is to be supplied to a heater 17 of a lean sensor 15 is computed. When Po<25W, i.e. at the time other than the low-speed low-load operation of an engine, a flag X is set, and a power decreasing value POTP is set at zero. Meanwhile, when Po>=25W, i.e. at the time of the low-speed low-load operation of the engine, the flag X is reset. At this time, the counted values C are decremented. When the engine operating state is in a region A before the completion of warm-up and the counted value C<L is judged, the resistance value RH of the heater 17 is computed when the lean sensor 15 is in the active state. A learning resistance value Ro indicating the RH is stored in a RAM 27. The power decreasing value POTP is set at zero. Meanwhile when C>L, the duty ratio of the power supply to the heater 17 is computed, and the power supply is controlled based on the ratio.

Abstract: PURPOSE:To offer a heat exchanger made of aluminum, which is light in weight and superior in productivity, for a radiator, a condenser, a heater core and an evaporator, by forming unitarily a frame material made of aluminum at the time of soldering of the same with a tube and a fin. CONSTITUTION:In case of fixing of a frame material 6 on both ends of a tube 2 having a bent part 5, at the time of soldeing of the flat tube 2 manufactured by rebending predetermined number of times in a meandering state to a fin 4 formed correspondig to each distance between straight tube parts 3 of the tubes 2, each of protruded parts 13 of the frame material 6 is made to fit in a space between each of the bent parts of the tube 2 and then the tube 2, the fin 4 and the frame material 6 are put into a soldering furnance in a body. The tube 2 and the fin 4 are soldered through a solder material added to either the tube 2 or fin 4 sides, and the tube 2 and the frame material 6 ares soldered through the solder material 14 formed on each of the insides of side plate parts 12. In other words, the tube 2, the fin 4 and the frame material 6 are soldered simultaneouly. With this construction, a fitting component for fixing the tube with the frame material is unnecessary and the titled heat exchanger becomes light in weight as the frame material is formd of aluminum. In addition to the above, as there is no tightening process for fitting the frame material to the tube, productivity is high.
