Patent JP-S6387762-A (JP)
Title: Manufacture of semiconductor device
Inventor: MIYAZAKI SHINICHI
IPC: H01L27/04
Filed: 1986-09-30
Abstract: PURPOSE:To improve accuracy of a resistance value and integration by forming a resistor layer after burying a polycrystal silicon layer in a field oxide film, thereby forming a resistor after levelling the surface. CONSTITUTION:A field oxide film 2 is formed on a semiconductor substrate 1 and a recessed part 6 is formed with a photoetching process and then a polycrystal silicon layer with an N-or a P-type impurity added is laminated and furthermore, a photoresist layer 9 is deposited on an upper part of the polycrystal silicon layer 7 to form a flat surface. Subsequently, an anisotropy etching is performed with a gas having an almost identical etching rate on the polycrystal silicon layer 7 and the photoresist layer 9 and, when the above photoresist layer 9 and the silicon layer 7 are removed, a resistor layer 7A consisting of polycrystal silicon is left as it is. After an insulating layer 4 is selectively formed on the resistor layer 7A, the resistor 4 is completed by attaching lead-out metals 5 for electrodes to both ends of the resistor layer 7A.

Title: Transfer paper separating device
Inventor: EGUCHI TAKAYUKI
IPC: G03G15/00
Filed: 1983-12-12
Abstract: PURPOSE:To eliminate the need for a separation charger, separation pawl, etc., and take an entire-surface copy through simple constitution by bringing the front end of transfer paper into contact with a separation auxiliary roller where the transfer paper leaves a photosentitive body, and separating the transfer paper by its rotary movement. CONSTITUTION:The fed transfer paper 2 contacts the separation auxiliary roller 10 where its front end leaves the photosensitive body with its stiffness at the curved part of a driven roller 1b, and is attracted electrostatically to the roller 10 by charge charnged electrostarically. Further, the roller 10 moves with the conveyance force of the paper to a side wall 11b while rotating on a guide tray 11 to separate transfer paper 2 completely, and the roller 10 returns to its original poisiton because of the inclination of the tray 11. Therefore, neither the separation charger nor the separation pawl is necessary, so an entire-surface copy of an image is taken; and the separation auxiliary roller 10 returns automatically, so continuous separation is performed stably through the simple constitution.

Title: Measurement of rheumatism factor and measuring reagent thereof
Inventor: HASHIGUCHI YOICHI
IPC: G01N33/564
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To measure a rheumatism factor(RF) with high sensitiveness over the whole measurement area by using an IgM type rheumatism factor originating from rheumatism factor(RF) positive blood serum/plasma. SOLUTION: In measurement of a rheumatism factor, an IgM-RF purified from rheumatism factor positive blood serum/plasma is used. In this case, the rheumatism factor positive blood serum/plasma means that prepared from a patient having a certain kind of disease diagnosed directly/indirectly from the existence of the IgM-RF. This kind of disease is chronic articular rheumatism (RA), various kinds of collagen disease, liver disease, infectious disease, or the like. Any γ-globulin originating from a human or an animal can be used without any restriction as the γ-globulin mixed with the IgM-RF. This measuring method is applicable to immunoassay such as immuno-turbidimetry (TIA) and latex turbidimetry.

Title: Method and device for natural language processing
Inventor: SAITO YOSHIMI
IPC: G06F17/22
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To easily detect whether outputted natural-language expressions are known as coocurrence or not. SOLUTION: For example, in the KANA(Japanese syllabary)-KANJI (Chinese character) conversion processing, an editing control part 102 checks whether a word group held in a word string candidate holding part 108 matches coocurrence information or not. When the word group in language information matches (or doesn't match) coocurrence information, the editing control part 102 adds coocurrence presence (or absence) information (for example, underline) indicating the result to a pertinent candidate character string to output it to a display part 103. Thus, it is easily detected by coocurrence presence (or absence) information given to the character string outputted to the display part 103 that expressions are judged to be known as coocurrence or are not stored as coocurrence.

Abstract: PURPOSE:To make chip size smaller, and to enable operation at high speed, also by coupling a PLA circuit section and a gate array circuit section by a signal from a flip-flop circuit section reversible by a clock signal from one system of said circuit sections. CONSTITUTION:Dotted lines represented transfer paths for signals, asynchronous signals from the asynchronous drive system gate array circuit sections (B) are converted into synchronous signals by the flip-flop section (C), and the synchronous signals are transmitted over the PLA system circuit constitutional section (A). When signals from the PLA circuit section are coupled with the gate array circuit sections, the PLA circuit section is synchronized by the flip-flop circuit section and coupled with the gate array circuit sections because the PLA circuit section is driven synchronously. An asynchronous circuit can also be treated by adding informations from the gate array system circuits to a PLA system, and a circuit extending over a wide range can be constituted. A synchronous circuit is incorporated in a small region by incorporating it into the PLA.

As a result, positive pressure and negative pressure are alternately effected, and accordingly, a ball valve 58 is opened so that the case 1 and a vacuum actuator (not shown) are communicated with each other through pipe lines 51, 67 and the like. Then, a control rack is driven to its full close position by the actuator through the intermediary of a transmission means, and therefore, fuel from a pump section in a unit injector is cut off.

Filed: 1988-09-20
Abstract: PURPOSE:To make the rising of the light flux quick and resolve the difference in brightness by making the resistance value per unit length of a heater at the position with a small potential gradient larger than that at the position with a large potential gradient. CONSTITUTION:The width W1 of a mesh heater 21 is made large at the bent section 22a of a heater 20, and the width W2 at the linear section 22b of the heater 20 is made smaller than W1. The current resistance value at the bent section 22a of the heater 20 is low, the heating value is low, on the other hand the current resistance value at the linear section 22b is high, thus the heating value is large. As a result, linear sections 8a and 8b are heated by the heater 20 more than the bent section 7, and the mercury vapor pressure at the linear sections 8a and 8b is increased. The mercury excitation level is unified over the whole lamp, the emission quantity of ultraviolet rays is made equal, and the brightness along the axial direction can be unified.
