Title: Optical recording medium and disk plate used for the same and its production
Inventor: MATSUDA RIKI
IPC: G11B7/24
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To shorten the production time of a disk plate for optical recording medium, to facilitate the control of uniformity and to improve the yield and productivity. SOLUTION: A metallic film consisting of tantalum, etc., used for an enhancement layer 13 is formed on a substrate 12 and a metallic film consisting of chromium, etc., forming a guide layer 14 is formed on the metallic film and is spirally and concentrically worked by etching. Further, a metallic film consisting of tantalum, etc., used for an interference layer 16 is formed on the guide layer 14. The disk plate produced in such a manner is put into a heating furnace, by which both metallic films are oxidized and are formed to transparent dielectric films. At this time, the chromium of the guide layer 14 is more hardly oxidized than the tantalum and is, therefore, not oxidized. At the time of etching the chromium, the tantalum is not etched and the production of the low-noise disk substrate is made possible.

Title: Contour correction circuit
Inventor: CHO HYUN-DUK
IPC: H04N5/208
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a contour compensation circuit for a video signal by which a compensation level is individually adjusted depending on positive and negative waveforms. SOLUTION: A delay section 210 in this contour compensation circuit delays a received luminance signal by a 1st prescribed time to generate a 1st delay signal 2111 and delays the generated 1st delay signal by a 2nd prescribed time to generate a 2nd delay signal 2121. A current luminance signal is added to the 2nd delay signal by an adder 221 and the sum signal 2211 is given to a variable amplifier 250, from which 1st and 2nd variable amplifier signals 2511, 2521 are outputted. A selection section 260 compares the sum signal 2211 with a reference signal 2111 and its comparison result 2411 gives selectively the 1st variable signal 2511 or the 2nd variable signal 2521 to a subtractor 222, where the 1st variable signal 2511 or the 2nd variable signal 2521 is subtracted from the 1st delay signal 2111 to provide an output of a contour compensation signal.

Title: Data segmenting system
Inventor: KAGEYAMA MINAKO
IPC: G06T3/00
Filed: 1987-03-23
Abstract: PURPOSE:To reduce the hardware quantity and to improve the data segmentation processing capacity by making use of a DMAC (direct memory access controller) function to the segmentation control. CONSTITUTION:A control part 13 sets previously the number of lines corresponding to each area, the segmenting area designation information and the head address of a transfer area in a memory 12 at a DMAC10 for the image data given from a data source 14. Thus a desired segmenting area of the source 14 is stored in a segmentation data storing area 12S of the memory 12 and other areas are superscribed on a partial writing area 12R where a prescribed writing unit is not needed. Therefore a segmentation-only circuit is omitted to realize the reduction of the hardware quantity, the effective use of the memory capacity and the reduction of the data segmenting time.

Title: Semiconductor memory
IPC: G11C11/41
Filed: 1992-03-25
Abstract: PURPOSE:To speed up operation by arranging and connecting bit line load circuits on the center of plural memory cells or bit lines. CONSTITUTION:The bit line load circuits 11, 21 are arranged and connected on the center of plural aligned memory cells, i.e., the center of plural bit lines 1, 2. Resistance from the circuits 11, 21 up to the uppermost part of the bit lines is R/2 and resistance from the circuits 11, 21 up to the lowermost part is also R/2. Thereby the resistance of the bit line influenced by reading is R/2 independently of the selected memory cell. Consequently the voltage drop of the bit lines 1, 2 is reduced to a half as compared with a convensional memory increasing a potential difference in reading data. Since resistance on the endmost part of the bit lines 1, 2 is reduced to a half of a convensional value in the case of charging the disccharged bit lines 1, 2 by the circuits 11, 12, the precharging time can be shortened.

Abstract: PURPOSE:To lower voltage on writing, to prevent the erroneous erasure of a non selective cell and to obviate soft-write at the time of read by making the source and drain of the cell different in impurity concentration and forming source and drain of the cell of asymmetric structures. CONSTITUTION:A memory cell transistor with a floating gage FG, a control gate CG and a source and a drain is provided. A p-type impurity layer in high concentration is formed so as to surround an n-type impurity layer in high concentration in one of the source and drain, and the other is formed on an n-type impurity layer in low concentration and a high concentration impurity in a section separate from a gate end. The strength of an electric filed is made steep and a large number of hot electrons are produced in the former case when it is used as the drain, while in the latter case hot electrons are difficult to be produced because the electric field is relaxed in an n<-> type impurity layer. Accordingly, voltage is lowered on write, and the erroneous erasing of a non selective cell is prevented while the generation of hot carriers at the time of read is inhibited and a software error can be obviated.
