Title: Optical disk
Inventor: SATO ISAO
IPC: G11B7/00
Filed: 1986-12-19
Abstract: PURPOSE:To realize an effective substituting process of sectors at high speed by providing a mapping sector which divides a disk into blocks and records the address correspondence information between the defective and substitute sectors at every block. CONSTITUTION:A disk 1 is divided into blocks #1-#N and the test data is recorded and reproduced at all sectors of each block to check the presence or absence of a sector address error, a data error or a defect of a data part. Then the mapping data on a mapping memory 17 which records the address correspondence information between a defective sector having an error and its substitute sector is stored in a mapping sector M1 or M2. In this case, the number of tracks of a block is selected at the value that enables a high-speed retrieval, i.e., within the movable range of the actuator of an optical head 1. In such a way, the sectors are substituted for each other at high speed.

IPC: H01M4/26
Filed: 1990-11-09
Abstract: PURPOSE:To enhance operating voltage, capacity, high-rate discharging characteristic, and the oxygen gas absorbing performance at charging, by fabricating a neg. electrode using a specific hydrogen storage alloy, and upon assembly of a battery, allowing the alloy to initiate cracks within the battery to specify the mean particle dia. CONSTITUTION:A neg. electrode is fabricated from a hydrogen storage alloy having a mean particle dia. from 50 to 120mum, and a battery is assembled with this neg. electrode. Within this battery crackes are generated in the alloy to make the mean particle dia. of alloy below 50mum. Accordingly the reacting surface area of the alloy increases, and an active alloy section is exposed to the surface to enhance the reactivity of negative electrode. Thereby the working voltage when battery is discharging at a low temp. or with high rate can be enhanced, and generation of hydrogen gas in the later period of charging be suppressed by means of quick charging, and the absorbing performance for oxygen gas generated from the pos. electrode at the time of charging be improved.

Title: Connection device of semiconductor integrated circuit and manufacture thereof
Inventor: KIN SAIKOU
IPC: H01L21/3213
Filed: 1991-11-20
Abstract: PURPOSE: To reduce a cell area, by preventing a conductive layer or a substrate located at a lower part from being exposed by an etching stop layer, and connecting a conductive layer to be connected to a lower wiring layer. CONSTITUTION: A contact hole 20 is formed by etching one portion of a second insulation layer 4 and a first insulation layer 2, by utilizing a mask B for etching stop layer for forming an etching stop layer 3A and a contact mask C located in a mask A for wiring for forming a partial wiring 1A. Therefore, the width of the upper part of the contact hole is the minimum width that can be formed from the contact mask pattern process. Also, the lower width is formed to be a smaller width due to the etching stop layer 3A. Therefore, even if the contact hole 20 is formed toward one side surface at the position of the wiring layer 1A, the side surface of the lower wiring layer 1A is etched since the etching stop layer 3A exists, thus preventing another conductive layer at a lower part or a substrate from being exposed.

Title: Antiskid control device
Inventor: OIKAWA HIROTAKA
IPC: B60T8/34
Filed: 1990-11-09
Abstract: PURPOSE:To certainly execute antiskid control while ensuring running stability by reducing the braking force difference between left and right front wheels when either one of the left and right front wheels is antiskid-controlled and the road frictional coefficient is different between the left and right wheels by a determined value or more. CONSTITUTION:The antiskid control conducted by a controller 9 is based on the operation for calculating a slip ratio lambda from a dummy vehicle speed V and a wheel speed Romega on the basis of the signal supplied from each wheel speed sensor S to set a modulator 3 to any mode of pressure increase, pressure reduction, and holding. Whether either one of the front wheels is under antiskid control or not is judged, and in the case of YES, whether the other front wheel is under antiskid control or not is judged. In the case of NO and when the pressure reduction is continued even after the pressure reducing time of one front wheel exceeds a determined value, the other front wheel which is not antiskid-controlled is forcedly reduced in pressure to reduce the braking force difference between both the wheels.

Title: Data coding system
Inventor: MIYAOKA SHINICHIRO
IPC: G06T9/00
Filed: 1986-12-24
Abstract: PURPOSE:To prevent sharp lines or edges from being blurred while keeping high compression performance by means of simple coding/encoding processing by dividing image data into blocks with unequal length and coding the division structure and the block coding data into tree structure data. CONSTITUTION:Image data are divided into blocks thinnly in a part having a sharp brightness change and roughly in a part having a moderate brightness change. The greater part of a density image is occupied by the part to be roughly divided. The coding of said block is executed by the approximation of the brightness change based upon a bilinear function and the quantization of the factors of the function. Since each block is coded by the factors of four bilinear functions independently of the size of the block, the volume of coded date is reduced and the compressibility is improved when the roughly divided block part is increased. Since a smaller block has a larger average distortion about the average distortion of each picture element, the characteristics have effects for a picture improved at its adaptation to human's visual characteristics and compression performance. Data formed as tree structure can describe the block divided structure by the small number of bits and the overhead of processing at the time of decoding can be reduced.
