Title: Deciding method for maximum operating point of solar battery
Inventor: KUME TSUNEO
IPC: G05F1/67
Filed: 1993-09-01
Abstract: PURPOSE:To shorten the tracking time of the maximum power by performing the approximate calculation of the maximum power operating point from operating voltages or operating currents at plural operating points in the neighborhood of the maximum output obtained from the output characteristic of a solar battery and the value of power. CONSTITUTION:The output of the solar battery 1 is controlled by providing a main circuit 10 which feeds the power generated at the solar battery 1 to load equipment 4 via a smoothing capacitor 2 and a power controller 3, and providing a voltage detector 5 which detects the output voltage of the solar battery 1 or a current detector 8 which detects an output power source. In such a case, the maximum operating point of the voltage or current can be found by the computation of a quadratic or higher approximate expression from the operating voltage or operating current at three or more operating points in the neighborhood of the maximum output operating point of the solar battery 1. For example, when the maximum power is found by the voltage, the power at second and third operation points shifted by share of deviation voltage by load disturbance, etc., before and behind the first operating point in the neighborhood of the maximum power operating point are measured, respectively, and they are approximated by a quadratic expression, and it is computed, then, the maximum operating point can be found.

Title: Buffer storage control system
Inventor: KUBO KANJI
IPC: G06F12/08
Filed: 1983-12-26
Abstract: PURPOSE:To shorten the transfer time of a block by executing the processing of a block transfer request supplied from another buffer storage device (BS) without waiting the processing of a main storage device (MS) for block transfer request from a presceding respective BS. CONSTITUTION:When a block transfer request is sent from only one BS, a comparator 24 sends an address to the MS14 through an address line ADR. Receiving the address, the MS14 starts reading and sends the requesting device, data and a signal ADV indicating the sending of the data to the BSs 11, 12. If the request is sent form the BS11 or 12 itself in accordance with the display of the requesting device, the corresponding BS inputs the data. When block transfer requests are simultaneously generated from both the BSs 11, 12, a comparator 24 compares both the addresses, and in case of coincidence, sets up a coincidence holding latch 25. When the latch 25 does not indicate coincidence, a selector SEL23 selects only one BS' in accordance with previously fixed priority.

Title: Composition for molding smc
Inventor: NAKAZAWA KAZUMA
IPC: B29C70/10
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To make the appearance of a fibrous pattern or a grained pattern on the surface of a molding by blending a a heat-curable resin material for a molding by a sheet molding compound(SMC) molding process with rayon fibers. SOLUTION: A fibrous pattern is made to appear on the surface of a molding by using colored rayon fibers or originally colored rayon fibers in an SMC resin molding composition and thereby, the design characteristics are improved with an impressive feeling. Further, when compratively shorter and somewhat thick ray on fibers are used, a granite-touch pattern is obtained. On the contrary, the appearance of such a feeling as peculiar to a hand-made Japanese paper is realized by using somewhat longer rayon fibers. The rayon fibers are preferably of such a composition for molding SMC that is used for decorative molding in the blending ratio of 0.05-5 wt.% to 100 wt.% thermoplastic resin, the fiber length being 0.1-100 m/m and the fiber thickness being 1-300 denier. One of the reasons for selecting the rayon fibers is that these fibers are easily colorable and highly durable.

Title: Preparation of damage estimating specimen during semiconductor manufacturing process and estimatting method therefor
Inventor: YABUMOTO CHIKAKUNI
IPC: G01N17/00
Filed: 1989-09-22
Abstract: PURPOSE:To determine process conditions where damage is low or not present, by a method wherein material which does not mingle during plasma process or subsequent specimen manufacturing process is previously sucked on a surface, and damage is estimated by analyzing the distribution of the component in the depth direction. CONSTITUTION:A specimen 2a is dipped in material which does not mingle with a surface during a process subsequent to heavy water 1, and a specimen 2 on which surface said material is sucked is made. When an Si wafer 2 as the specimen is subjected to dry-etching, heavy water 3 is diffused into the inside. A protecting film is formed on the surface by vacuum-depositing amorphous Si 4, and secondary ion mass spectrometric analysis is performed. By dry-etching using Ar of different ion energy, a distribution curve is obtained wherein the depth is shown on the horizontal axis and heavy hydrogen concentration is shown on the vertical axis. A critical point is set as the ion energy which rapidly extends with respect to the half width value of the heavy hydrogen profile before etching. It can be estimated that damage is generated in the region where energy exceeds the critical point.
