Title: Pwm inverter control system
Inventor: OMORI YOICHI
IPC: H02P23/07
Filed: 1991-01-17
Abstract: PURPOSE:To suppress magnetic noise by determining the magnitude of a voltage command vector based on an output from a voltage command operating section in a PWM inverter, comparing thus determined magnitude with a triangular wave or saw-tooth wave carrier and selecting a voltage vector other than a zero vector. CONSTITUTION:Input currents Iu, Iv to a linear induction motor 6 are determined through CTs 8a, 8b and subjected to rotary coordinate conversion 9. They are then added or subtracted 2a, 2b to/from the output of a command operating section 1 and fed to a voltage command operating section 3 thus determining voltage commands Vd, Vq. Operation of V=(Vd<2>+Vq<2>)<1/2> is then performed at a voltage operating section 40 thus obtaining a voltage command V. The voltage command V is then compared with a triangular or saw-tooth carrier Car generated from a carrier generator 41 and VZ-l is outputted if V>Car whereas VZ=0 is outputted if V<Car. A switching signal output section 43 selects VZ=1, rather than VZ=0, from the output of a comparator 42 and drives a PWM inverter 5 with signals Su-Sw. According to the system, zero vector applying timing is limited and uncomfortableness due to magnetic noise can be alleviated.

Title: Interimage coding signal decoding method and device
Inventor: TOOMASU KUMEROFU
IPC: H04N19/503
Filed: 1983-03-18
Abstract: To save transmission capacity, only those parts of a single frame of a moving-picture signal (video signal) are transmitted in digital form which have changed compared with the preceding single frame as far as this is known to the receiver. The transmission coding process can be carried out with a continuous operating speed determined by the data rate of the transmission path since both the change decisions and the supplied uncoded frame data words are temporarily stored at the transmitter end for data processing and are supplied to the coding process after a variable delay. A temporary storage at the channel end can be omitted both in the transmitter and the receiver. The received frame data are directly decoded and the associated address data are used for updating the video information items located in the frame store which are only reproduced after a delay time - between zero and one frame period.

Filed: 1990-02-28
Abstract: PURPOSE:To simplify a process and attain a refined pitch and further, reduce a cost by covering the whole surface of a wafer after forming base metallic parts with a metallic film for forming protrudent electrodes and then, forming the protrudent electrodes selectively on the base metallic parts through partitioning the metallic film for forming protrudent electrodes. CONSTITUTION:A protection film 2 on electrodes 1 is bored, and BLMs(Ball Limiting Metalization) 3 are formed thereon. Then, a solder film 4 of a desired film thickness and a desired composition is formed by a vacuum evaporation and the like. A groove 6 for partitioning the solder film is formed on the boundary between the solder films 4 by projecting a laser beam 5 on it. By heating the solder films 4 to a solder fusing temperature after coating the surfaces of the solder films 4 with fluxes, semi-spherical solder bumps 7 are obtained on the BLMs 3 by virtue of surface tensions. Making the groove 6 for partitioning the solder film form the boundary, the solder film 4 shrinks into the right and left part respectively. Then, they change into sphere-like parts, each of which forms the shape in that the surface area is shrinked into the minimum one, on the BLMs 3 having good wettabilities for the solder films. In such a manner, by the fine working using the laser beam, the solder film formed on the whole surface of a wafer is partitioned all over the surface, and can be changed into the solder bumps.

Title: Air flowmeter

IPC: G01F1/684
Filed: 1987-02-27
Abstract: PURPOSE:To accurately measure intake air capacity by forming an intake air passage in a venturi shape and placing the air flow in a sensing passage in a laminar layer. CONSTITUTION:When an internal combustion engine begins to operate, air is sucked from an air cleaner arranged at the tip part of an intake pipe and passes in a flowmeter 100 as shown by an arrow A. Further, the sensing passage 21 is open to the narrowest venturi parts of respective intake passages 29, so the air flowing in the sensing passage 21 is sucked efficiently into the respective air intake passages 29 from communicating paths 22. Here, the air intake passages 29 are formed in the same shape and at an equal distance to adjacent passages and at an equal distance from the center parts of the respective passages 21. Consequently, the air flowing in the passages 21 flows uniformly out of the center of the rear end parts of the passages 21 while spreading radially. The air flow, therefore, enters the laminar state securely and is accurately detected.
