Title: Rotation controller for motor
Inventor: SUZUKI KAZUHIRO
IPC: H02P29/60
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent burning of a motor and to ensure high reliability of a protective region by lowering the input voltage of the motor, when the input voltage of the motor is kept for a constant time in a specific condition. SOLUTION: This controller defines a region satisfying V>ar+d or V>c<3> +d (a, c, and d are constants) as a protective region, when the axis of ordinates represents an input voltage V and the axis of abscissas represents the rotational speed r of a motor. And its input voltage increase on the occasion of reduction of the rotational speed by the degree of the input voltage V, is adjusted, and if it reaches a voltage within the protective region. the input voltage value is lowered after the passage of a certain time, and the rotational speed of the fan motor is lowered. Consequently, a voltage to be applied to the motor has an upper limit also keeping it within a reliable protective region, and burning of the motor is prevented. Along with it, it becomes possible to set a protective region in accordance with the difference of motors.

Title: Alarm device of electronic watches
Inventor: TOYODA MITSURU
IPC: G04C21/02
Filed: 1978-03-22
Abstract: PURPOSE:To generate wide band alarm sounds to be produced with a simple and miniature constitution by driving plural sounding bodies with one set of driving coil. CONSTITUTION:When square pulses are applied to the base of a transistor 9, the transistor 9 repeates ON and OFF, causing the diaphragm 6 of an electromagnetic buzzer to be vibrated by a dirving coil 4. At the same time, the voltage having been boosted by the coil 4 drives the piezoelectric element 8 provided with a diaphragm 7. Hence, the different sounding bodies are simultaneously driven by one set of driving coil, thus the alarm sounds of a wide band may be produced with the simple and miniature constitution of a less number of parts using an electromagnetic buzzer of a narrow band and good timbre and a piezoelectric buzzer of a wide band and not so much good timbre.

Title: Supercharging pressure control device for exhaust turbosupercharger
Inventor: HATANAKA KEIJI
IPC: F02B37/22
Filed: 1984-02-25
Abstract: PURPOSE:To aim at improving the fuel consumption and exhaust gas properties of an engine, by using both flap for adjusting the flow rate of exhaust gas at the inlet of an exhaust turbine and bypass valve disposed in a passage bypassing the exhaust turbine, and as well by increasing the opening degree of the bypass valve when an abnormality of the flap is detected. CONSTITUTION:A flap at the inlet of an exhaust turbine is set at an optimum position in accordance with the amount of intake-air and the rotational speed of an engine which are detected by a means for detecting the operating condition of the engine. Further the amount of exhaust gas which bypasses the exhaust turbine is controlled by a bypass valve controlling means. When a means for detecting an abnormality of the flap detects an abnormality of the flap, a bypass compensating means increases the opening degree of the bypass valve to discharge a part of exhaust gas to the outside by way of a bypass passage without letting the same flow through the flap and the exhaust turbine, thereby it is possible to prevent the pressure of exhaust gas upstream of the flap from excessively rising.

Title: Semiconductor device and method and device for manufacture the same
Inventor: AOKI EIICHIRO
IPC: H01L23/06
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To simplify the manufacturing process of a semiconductor device so as to reduce the production cost of the device without performing heating treatment in the manufacturing process, by sealing a cavity section housing a semiconductor element by sticking a translucent cap to the upper surface of the cavity section through an ultraviolet-curing sealing compound. SOLUTION: A cavity section 1b is sealed by putting a translucent glass cap 5 on the cavity section 1b so as to cover the section 1b. The cap 5 is stuck and fixed to the upper peripheral edge of the section 1b with an ultraviolet- curing sealing compound. Consequently, no such heating treatment is required that the cavity section 1b is charged in a furnace while the cap 5 is put on the section 1b in the manufacturing process of a semiconductor device 1, because, when a sealing compound layer 6 of the sealing compound cured by ultraviolet ray is irradiated with ultraviolet rays, the cap 5 is stuck to the section 1b. Therefore, the semiconductor device 1 can be manufactured continuously without being affected by the heat-resistant temperature of a semiconductor element 2 constituting the device 1 and, in addition, requiring no such a long time as the heating time.

Abstract: PURPOSE:To decrease the number of interruption equipment identification numbers, facilitate the extension of an I/O unit, and reduce hardware by allowing a monitor program to pass the right of execution to one of plural task programs according to an interruption from an interruption source and executing the program. CONSTITUTION:A task program is divided into groups previously and interruption equipment identification numbers are assigned to the respective groups. Then, a common interruption equipment identification number (a) is generated for interruptions from respective I/O units 1-(m). The interruption cntrol program of the monitor program performs control so that the right of execution is passed to respective task program 1-(m) successively for the interruption equipment identification number (a). Each task program when receiving the right of execution checks on the contents of the interruption register of the I/O unit which belongs to the program and decides whether an interruption factor is generated or not. When there is the interruption factor, the task program is executed to perform specific I/O processing, and when no, the right of execution is passed to a monitor.
