Title: Capacitor switching-control device
Inventor: YOKOTA REI
IPC: G05F1/70
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency in a power factor and to prevent harmonic interferences by automatically performing the break for preventing harmonic interference of a capacitor and the closing for improving the power factor. SOLUTION: A current flowing through a power capacitor 4 is detected by a current transformer 8, a capacitor switching-control device 9 is broken off by a high-voltage electromagnetic contactor 6 via a switching control device 7, when the harmonic current distortion ratio of the detected current is larger than a prescribed value to protect the capacitor. After the break off, when the harmonic voltage distortion rate of a detection voltage, where the system voltage of high-voltage mains 1 is detected by a transformer 10 for a measuring instrument, becomes smaller than a prescribed value, a high-voltage electromagnetic contactor 6 is thrown to improve the power factor of the system.  In this manner, while the capacitor has been thrown in, the capacitor is broken off based on the harmonic current distortion rate, whereas with the capacitor broken off, the capacitor is thrown in based on the harmonic voltage distortion rate.

Abstract: PURPOSE:To obtain the communication network system which is adapted to its operation conditions and optimizes the operation efficiency by providing a fuzzy control unit for controlling access to a communication line network from respective terminals. CONSTITUTION:Information regarding an operation state used for inference is transferred from a slave station together with transfer data at the time of data transmission and a CPU 10 sets them in the subordinate station information table 23 of a memory 12 from a transmission controller 11. The data which are gathered here consists of the frequency of data transfer (the number of times of data transfer requests per unit time), the amount of data transfer (transfer quantity per unit time), and an elapsed time (elasped time from last data transfer). A mechanism 13 operates independently of the CPU 10 to input respective pieces of information on the transfer frequency s1, transfer amount s2, and elapsed time s3 and output a polling interval V obtained by inference. The output V is set in the polling interval table 26 on a memory 12 by subordinate stations.

Title: Stamp in thin case
Inventor: HIDAKA MASAYUKI
IPC: B41K1/58
Filed: 1997-04-12
Abstract: PROBLEM TO BE SOLVED: To easily seal a stamp with one hand without requiring a support by setting an adhesive on an upper face of the stamp formed thin and adhering the stamp to a finger, and to enhance portability by storing the stamp in a thin case. SOLUTION: One end of a film-like synthetic resin is fixed to one side 11 of a plate body 3, thereby forming a cover 5. A projecting part 7 is formed to prevent an adhesive 2 from adhering to the cover 5. A stamp 1 is inserted to the projecting part 7, so that the adhesive 2 is effectively prevented from adhering to the cover 5. At the same time, the stamp 1 can be easily detached from a finger. When the stamp is to be sealed, the cover 5 is pushed open and the stamp 1 is attached to an index finger, etc. At this time, if a rear face of a stamp paper is supported by a thumb, the stamp is sealed beautifully without using a stamp pad. The cover 5 is closed by an adhesive 12 after the stamp 1 is accommodated. If a vermillion inkpad 9 is embedded in a recess 8, it is conveniently not required to carry the vermillion inkpad 9 separately.

Title: Semiconductor laser array
Inventor: SEKIGUCHI YOSHINOBU
IPC: H01S5/00
Filed: 1987-05-25
Abstract: PURPOSE:To obtain a dense scanning line pitch, whose adjustment is simple, by differentiating the light emitting points of a plurality of semiconductor lasers, which have the approximately same oscillating wavelengths, in the laminating directions. CONSTITUTION:Steps are provided on the upper surface of an n-GaAs substrate 22 so as to form three planes having the different heights. Namely, an n-GaAs buffer layer 23, a lower clad layer 24, an active layer 25, an upper clad layer 26 and a P-GaAs cap layer 27 are laminated. When currents are injected through electrodes 28a, 28b and 28c, laser light beams, which have the approximately same oscillating wavelengths, are outputted from light emitting points 29a, 29b and 29c. When the currents are controlled, the light emitting points are independently driven. Since the step of the substrate 22 are intactly kept at the light emitting points, the points are separated by every 1.5 mum in the laminating direction of semiconductors. When, a semiconductor laser array is used in a beam scanning apparatus, the difference in heights of the light emitting points in the laminating direction can be used for the interval of the scanning lines. Since the scanning lines can be horizontally kept with respect to the scanning direction, adjustment is simple.

Title: Structure of throttle body
Inventor: KOZUKI MASANORI
IPC: F02M69/00
Filed: 1988-05-26
Abstract: PURPOSE:To prevent sudden change of fuel flow due to turning of a throttle valve so as to improve mixing with air by arranging injectors at the upstream side of the valve and lower side of gas supply passage, and specifying the fuel injection axis direction. CONSTITUTION:In a side flow type throttle body of a fuel injection type engine, an injector 1 injecting fuel is arranged at the upstream side of a throttle valve 3 and on the lower side of gas supply passage 2. A fuel injection axis direction P of injector 1 is set such that it crosses a part deviated downwards compared with a pivot 4 of the valve 3. Irrespective of open/close position of the valve 3, the fuel injected from the injector 1 is brought into contact with an upstream face F in a downstream direction part 3a of the valve 3. It is thus possible to prevent abrupt change of fuel flow caused by the open/close position of valve 3 so as to facilitate the mixing with air.
