Title: Irradiator
Inventor: ARUBAATO GUROITAATO
IPC: A61N5/06
Filed: 1988-10-17
Abstract: PURPOSE: To enable to cool a filter by arranging outward protruding cooling fins on the outer circumference of a frame. CONSTITUTION: A halogen lamp 3 emits a beam of light in the direction of a filter 5. The beam of light impinges at first on a heat resistance glass plate 18 and next on the filter 5. Accordingly, the heat resistance glass plate can keep a part of the heat, however, water contained in plastic disks 6 and 7 as well as in a hollow space 9 are warmed. The water in the hollow space 9 heated via a thin plate dipped in the water transfers the heat to an aluminum frame 8 and a cooling fin 10. When operated a fan, air is sucked along the cooling fin 10 and flows in the direction of arrows around the filter in the inward direction of its radius along the inner plastic disk 6, then, the disk 6 is cooled. From this time, air flows to the fan 14 through a circular gap 19, then, flows from the fan to the outside air.

On the other hand, a movable lens bush 5 is slidably fitted to the movable retainer plate 3 so as to be arranged opposite to the fixed lens bush 4. Heat insulating materials 6 are respectively provided in the lens bushes 4 and 5 in such a manner that the distance between the material and the molding surface of lens changes continuously. During the cooling process in the molding of the plastic lens, the cooling speed of the molten resin, which is injected to and filled into a cavity 7, can be controlled by the heat insulating materials 6 provided in the lens bushes 4 and 5. Accordingly, a favorable surface accuracy can be obtained and a highly accurate plastic lens can be provided. In addition, because no heater or the like is necessary, the cooling time of the lens can be shortened.

Filed: 1985-11-21
Abstract: PURPOSE:To make low cetane value fuel positively ignitable at the whole driving range, by adjoining an ignition device to the inside a subsidiary chamber, while setting up an injection nozzle which adjoins a sub-nozzle hole to the vicinity and main nozzle hole to a main combustion chamber, respectively. CONSTITUTION:A subsidiary chamber 3 is formed in a piston top 1 in succession to the upper edge side of a main combustion chamber 2, and an ignition device 10 is set up in this subsidiary chamber, while an injection nozzle 5, adjoining a sub-nozzle hole to the vicinity and a main nozzle hole 9 to the main combustion chamber 2 respectively, is set up as well. And, at the time of light load, atomized fuel of low cetane value is sprayed to the inside of the subsidiary chamber 3 from the sub-nozzle hole 8, making an air-fuel mixture inside the subsidiary chamber 3 into richness, whereby it is quickly burned with ignition by the ignition device. At the time of medium, high load, such spray as being large in grain size is sprayed to the inside of the main combustion chamber 2 even from the main nozzle hole 9, making it into wall surface evaporation, whereby self ignition is carried out by heat energy of the subsidiary chamber 3 and a flame. Thus, at the time of low temperature starting or low load, even low cetane value fuel is positively ignitable and, what is more, pale smoke and unburned matter in combustion are reducible.

Title: Piezoelectric actuator, and electronic apparatus fitted with the piezoelectric actuator
Inventor: IINO AKIHIRO
IPC: H02N2/12
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic motor with increased drive force. SOLUTION: This is a bimorph type piezoelectric actuator 1, where six sheets of piezoelectric substances 11, 12, 13, 14, 15, and 16 are stacked integrally. The piezoelectric substance 12 is thinner than the piezoelectric substance 11 and extends and shrinks in the same direction with the same voltage as that of the piezoelectric substance 11, and the piezoelectric substance 13 is thinner than the piezoelectric substance 12 and extends and shrinks in the same direction with the same voltage as that of the piezoelectric substance 11.  The piezoelectric substance 14 shrinks and extends in the reverse direction with the same voltage as that of the piezoelectric substance 11, and the piezoelectric substance 15 is thinner than the piezoelectric substance 14 and shrinks and extends in the same direction with the same voltage, and the piezoelectric substance 16 is thinner than the piezoelectric substance 15, and shrinks and extends in the same direction with the same voltage as that of the piezoelectric substance 14. Therefore, each extension and shrinkage of the piezoelectric substances 11, 13, 13, 14, 15, and 16 all contributes to the drive force without hindering the extension and shrinkage of other piezoelectric substances.  Accordingly, since piezoelectric actuator 1 becomes one which is of simple structure and moreover has increased output and efficiency by more than conventional ones in the same output, the actuator can be downsized and also achieve power consumption more than the conventional one.

IPC: H02P7/29
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To correctly detect the motor current value and correct it without providing an expensive circuit such as a sample holding circuit by detecting the motor current value from inter-terminal voltage of resistances series-inserted in first and second arms composed of a pair of semiconductor elements, and correcting the motor current value on the basis of a second duty ratio. SOLUTION: A unidirectional detecting type current detecting circuit 40 connected to resistances R1, R2 of an H-bridge circuit detects a motor current (i') and inputs it to a correcting circuit 41. The current (i') inputted to the correcting circuit 41 is corrected on the basis of a second duty ratio D2 defined by a function of a first duty ratio from an FET gate driving circuit 371, and fed back to a subtracter. In detected current waveform passed through a low- pass filter with cutoff frequency sufficiently lower than PWM frequency, a current is regarded as balanced during one-cycle time of PWM, and a current ripple can be assumed to be sufficiently small in relation to the current effective value, so that the current detected value (i') has an error by the duty ratio D2 to the current effective value (i).

IPC: G06F13/00
Filed: 1990-09-28
Abstract: PURPOSE:To execute an application program without changing the address by comparing data in a pattern storage part with a bus signal line pattern outputted from a central processor. CONSTITUTION:A central processing unit 2 permits a control circuit 105 through an internal control line 205 to output the comparison result of a comparator 104. In the case of execution of software corresponding to a new data processor, the unit 2 suppresses the output of the comparison result of the comparator 104 from the circuit 105 through the internal control line 205. When it is found by the comparison result of the comparator 104 that a pattern of the bus cycle processed at present is registered in a pattern storage part 102, the control circuit 105 requests interrupt handling to the unit 2. With respect to interrupt handling, the latched state of the signal line of a common bus 120 is referred to understand the processing in an old data processor, and handling adapted to this processing is performed on the new data processor. Thus, the operation of past software is secured regardless of the change of an address map.

Abstract: PURPOSE:To feed the starting fuel corresponding to the temperature condition and surely and easily start an engine by using the temperature rise by the excitation of the coil of an electromagnetic switching valve as an output signal to operate the electromagnetic switching valve. CONSTITUTION:When a coil 12 is excited by a power source battery 36, the coil 12 is heated, and the temperature of the coil 12 gradually rises. The temperature of the coil 12 is detected by a thermistor 45, when it exceeds a preset value, a transistor 47 and a transistor 48 are turned off, thus the excitation of the coil 12 is cut off, an electromagnetic switching valve C is closed, and the feed of the starting fuel is stopped. The time until the temperature of the coil 12 reaches the preset value is longer as the ambient temperature becomes lower. The period when the electromagnetic switching value C is opened becomes longer, and the quantity of the starting fuel becomes larger. The quantity of the dense air-fuel mixutre fed to an engine in response to the ambient temperature of the engine is automatically controlled, thus the engine is smoothly started at any ambient temperature.
