Patent JP-S5559755-A (JP)
Title: Semiconductor memory storage
Inventor: NAGASAWA KOUICHI
IPC: H01L27/108
Filed: 1978-10-27
Abstract: PURPOSE:To prevent the false operation of memory, by obviating the injection of electrons from the back of a P-type semiconductor that a memory element of a dynamic type semiconductor device is formed on the surface when a circuit is operated by mounting a P<+>-type diffusion layer to the back of the semiconductor. CONSTITUTION:There are currents by a small number of carriers generated in a semiconductor substrate as one cause of the loss of the memory of an N channel RAM consisting of one transistor and one capacitor. Normally, a P-type silicon wafer 15 of the N channel RAM is bonded on a stage 20 by an alloy 19 of gold silicon and fixed, but a N-type region 16 is made up to one portion of the back of the substrate due to contact with gold when the concentration of the impurities of the P-type substrate is low. When electrons are injected from the N-type region 16 due to the sudden drop of the potential of the stage, the electrons reach to the memory capacitor, and memory is lost. The injection of the electrons can be prevented because the N-type region is not built up if the back of the wafer is beforehand changed into P<+>-type.

IPC: G09F3/10
Filed: 1988-05-31
Abstract: PURPOSE:To constitute the title material so that it can be stuck to an optimum position of a material to be stuck and to eliminate the need of the processing of a peeling processing process on the side of the material to be stuck by forming a peeling agent layer on at least a part of the surface of a base material and forming a heat adhesive resin layer on this main surface. CONSTITUTION:A sticking agent 10 contains a base material 12 which has been formed by, for instance, a raw material which is comparatively soft and can be cut with scissors, etc. such as paper, etc., and on one main surface of this base material 12, a masking layer 14 is formed. On the masking layer 14, a peeling agent layer 16 which has been coated with a peeling agent is formed, and on the surface of the peeling agent layer 16, for instance, a heat adhesive resin is extruded, while heating it and a heat adhesive resin layer 18 is formed by coating, etc. This heat adhesive resin layer 18 is formed so that it is melted at a prescribed temperature, can be stuck completely to a material to be stuck, and the sticking agent 10 is stuck to the surface of continuous base paper 20a being the material to be stuck. In such a way, the title sticking material is stuck to an optimum position of the surface of the material to be stuck, and a special peeling processing process becomes unnecessary.

Title: Communication function processor
Inventor: MARUYAMA IWAO
IPC: H04L29/10
Filed: 1992-05-26
Abstract: PURPOSE:To shorten communication processing time by executing data parts to be processed in parallel by individual EPUs in the case of executing the data processing of a certain communication event. CONSTITUTION:An i-th layer protocol processing process 32 requests an adjacent layer protocol processing process starting means 4 to succeed the data processing of its upper layer i+1. The means 4 generates an (i+1)th layer protocol processing process 33 and sets up the process 33 on a protocol processing process queue 5. In the case of succeeding the data processing of a lower layer i+1, the means 4 generates an (i-1)th layer protocol processing process 31. In the case of processing a communication protocol having multi- layer structure, the order of data processing does not exist when the data corresponds to respectively different addresses, but an operation layer management table 6 for managing layers being processed by respective EPUs and directories is used in order to execute data processing in parallel. An operation layer managing means 7 updates processing in each switching of processing. Thus, the parallel processing of data can be attained and the communication processing time can be shortened.

Title: Optical pickup device
Inventor: YAN KEUN YOUN
IPC: G11B7/095
Filed: 1993-06-03
Abstract: PURPOSE: To miniaturize a size and to reduce a weight by substituting a lens and other optical parts for holographic optical elements and constituting one module of an optical detector and laser diode. CONSTITUTION: A laser beam reflected by optical disk 40 is focused by a first and second holograms H1 and H2. This focused beam is detected with optical detectors 60a and 60b for tracking detection, and because of an increase in quantity of light in a part 'a', a signal detected with an optical detector 60a becomes larger than the one detected with an optical detector 60b. In this case, since it is possible to constitute one module of a laser diode and an optical detector, not only a reading speed is accelerated but also inexpensive mass- production becomes possible and the optical pickup device can be reduced in size and weight.
