Title: Semiconductor storage device
Inventor: MAKIHARA HIROYASU
IPC: H01L27/10
Filed: 1992-08-18
Abstract: PURPOSE:To enhance the degree of integration of a semiconductor storage device for which storage data are determined in the process of manufacture. CONSTITUTION:In a memory transistor Q6 constituting a memory cell a depletion region 8 is formed on the left channel directly under a word line 5, and further the depletion region 8 is in contact with the n-type region 2 on the source S side. When the word line 5 is at the low level, the transistor Q6 is nonconductive with respect to the source S side. Impressing a specified voltage to the drain side D expands a depletion layer in the offset region 10 on the drain side D. When the depletion layer then reaches the depletion region 8, the transistor Q6 is made conductive. Thus one memory transistor Q6 in the memory cell has two pieces of data corresponding to the conducting state and non-conducting state, respectively.

Title: Vapor permeation
Inventor: FRIESEN DWAYNE T
IPC: B01D53/22
Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To separate a vapor mixture by sufficiently decreasing the partial pressure of a vapor in a sweep stream so that the ratio of the partial pressure to the partial pressure of a vapor in a retentate stream is lower than a specific value. SOLUTION: It is presumed that a fluid supply stream contains two vapors A, B and that a membrane is more permeable to the vapor B than the vapor A. In addition, a vapor B-rich permeable substance stream and a vapor B-scarce retentat current are run counter to each other. Then the partial pressure of the vapor B on the permeation side of the membrane is retained using the counter-flowing sweep stream so that the partial pressure on the permeation side is sufficiently as low as 0.9 or less compared to the partial pressure of the vapor B in the sweep stream. Thus it is possible to remove a vapor from an organic vapor and obtain a permissible high retentate purity to become an effective and low-cost system.

Title: Sheet for grinding glass plate
Inventor: ISEDA TORU
IPC: B24D11/00
Filed: 1993-09-03
Abstract: PURPOSE:To provide a surface of a glass plate where there is little undulation and damages and micro-cracks are shallow and few by laminating a hard sheet for grinding made of the organic resin containing diamond powder of the specified mean grain size as the surface layer for the grinding and a soft sheet with the cushioning quality as the layer of the rear surface. CONSTITUTION:A hard sheet 3 for grinding made of the organic resin containing diamond powder is laminated on a soft sheet 1 with an adhesive layer 2 to make the desired sheet for grinding. The diamond powder of fine grain size where the mean grain size is 3mum or under is used. If the diamond powder whose mean grain size is >=4mum is used. micro-cracks of >=1mum in depth are likely to be generated in the surface of the glass plate, and to remove this, further grinding of several mum becomes unpreferably necessary. The grain size of 0.1-2mum is more preferable to increase the working and removing speed and to make it difficult to increase the depth of micro-cracks.

Filed: 1991-08-30
Abstract: PURPOSE:To supply an exact quantity of articles to a first belt conveyor by supplying the articles to the first belt conveyor through an intermediate belt conveyor having higher article-carrying speed than a second belt conveyor. CONSTITUTION:Articles A carried at a relatively slow speed by a second belt conveyor 46 arrive at an intermediate belt conveyor 48 and are carried at higher carrying-speed. Therefore, the articles A arrived at the second belt conveyor 46 are carried apart from the following articles even if the articles A are carried with mutually closed condition on the second belt conveyor 46. And, an article detecting means 50 located at the upperstream side end part of the second belt conveyor 46 can exactly count each article. The articles A sent to a first belt conveyor 40 from the intermediate belt conveyor 48 are stopped by means of a stopper means 42 located downstream at an end part and are retained on the belt conveyor 40.

Title: High definition television signal decoding system
Inventor: IZUMI YOSHINORI
IPC: H04N19/80
Filed: 1989-08-29
Abstract: PURPOSE:To improve the picture quality by combining an in-field interpolation processing and an inter-frame temporal filter processing eliminating loopback distortion due to an offset subsampling between frames at the encoder side appearing at a reproducing still picture. CONSTITUTION:The interpolation for decoding a MUSE signal at the receiver side is only the in-field interpolation and as to the component of the band caused with loopback distortion by inter-frame offset subsample at encoder side, it is eliminated by using a temporal filter employing a frame memory. That is, a difference between the current frame and the preceding frame is taken by a frame memory 3 and a subtractor, resulting that the difference output signal includes the loopback distortion due to the movement and the inter-frame offset subsample. Suppose that the distortion exists in 4-8MHz in the MUSE signal, then it is extracted by a 4-8MHz BPF 4, then its output mainly includes the loopback component. Then the component is subtracted from the current frame signal to reduce the loopback distortion.

Title: Ic card unit
Inventor: SATO SHUNJI
IPC: B42D15/10
Filed: 1989-08-29
Abstract: PURPOSE:To prevent the damage to a power supply circuit accompanying connection inferiority by detecting the opening and closing state of a protective shutter when an IC card is connected to a connector and controlling the supply of a power supply on the basis of the output thereof. CONSTITUTION:An opening and closing shutter 1b moves forwardly and rearwardly in parallel to the inserting operation connecting an IC card 1 to a connector 1a and conceals or opens a connector terminal 1c. When the opening and closing shutter 1b is normally opened, both of two shutter opening and closing detection lines L1, L2 become a VCC level and, therefore, when the output of the supply command line VL from a CPU 8 shows an H-level, predeter mined reference potential VCARD is applied to the power supply terminal of the IC card 1. When the opening and closing shutter 1b becomes closed or half-open, one of or both of two shutter opening and closing detection lines L1, L2 show a GND level and, therefore, an AND gate 4a is operated so that no power supply is applied to the IC card even when the output of the supply command line VL from the CPU 8 shows an H-level.

Title: Monitor line duplicate system
Inventor: IIDA EIJI
IPC: H04B1/74
Filed: 1990-08-22
Abstract: PURPOSE:To improve the reliability of a monitor system by adopting duplicate line structure for an intermediate supervisory means connected by an optical line, storing the operating state for each line into a memory and displaying the information of the selected line based thereon. CONSTITUTION:A line having connection addresses 1-2-1,1-3-1 in duplicate is formed to a network element 31 connecting to a 1st intermediate supervisory equipment S-SV2. Thus, since sets of information from two connection paths are informed to a center supervisory equipment 1 in the normal state, they are stored in memories 15,16 as separate information sets. However, when an interruption takes place in an optical line 20, since a 2nd intermediate supervisory equipment M-SV has no response from the 1st intermediate supervisory equipment S-SV2 through the connection address 1-2 via the optical line 20, the fault is informed to the center supervisory equipment 1 and written in the memory 1-2. Thus, even when the optical line 20 is interrupted, the supervisory information via the line 21 is written in the memory 16 and displayed by a display section 12, then the reliability of the supervisory system is improved.
