Title: Coating agent and its production
Inventor: HAYASHI KENZO
IPC: C09D1/00
Filed: 1991-01-22
Abstract: PURPOSE:To provide a inorganic/organic coating agent. CONSTITUTION:A coating film made from a polyisocyanate and an inorganic substance as the essential components has the properties of both the inorganic and organic substances, high hardness and flexibility. When a film is prepared by mixing a polyisocyanate with colloidal silica particles while controlling the evaporation rate of the solvent and the coagulation rate of the colloidal silica particles, the film can be prevented from forming pinholes otherwise formed by the CO2 generated by rapid reaction with water which is an inhibiting substance formed during coagulation. When a blocked polyisocyanate and sepiolite are heated in the first heating step to a temperature at which the polyisocyanate is not deblocked and the water of crystallization of sepiolite can be removed, and the polyisocyanate is then deblocked in the second heating step, the polyisocyanate can be prevented from reacting with the water of crystallization.

Title: Cathode-ray tube display unit
Inventor: TAKAKOSHI AKIRA
IPC: H04N3/20
Filed: 1979-01-20
Abstract: PURPOSE: To prevent the spot burning of CRT by detecting a synchronizing signal being cutoff and then by stopping or suppressing an electron beam by this detection signal.  
     CONSTITUTION: A horizontal synchronizing signal and vertical synchronizing signal are inputted to terminals 1 and 7 respectively. Once applied with an input signal, multivibrators 2 and 8 generate outputs of constant pulse width synchronizing with the input. This pulse width is set longer than signal synchronism determined by the time constant of resistance 3 and capacitor 4 or resistance 9 and capacitor 10. Those output signals are AND-ed by AND circuit 13 to exercise switching control over NAND circuit 14. A video signal from terminal 15 is inverted and amplified by circuit 14 and then led out to lead line 20. Once the vertical synchronizing signal is cut off, vibrator 8 and circuit 13 generate outputs of "0" to close circuit 14, and a collector-applied voltage appearing at line 20 as it is applied to a CRT display circuit to stop the beam. Even when neither horizontal nor vertical synchronizing signal is inputted, circuit 13 generates an output of "0" to bring similar operation to effect.

Abstract: PURPOSE:To make all parallel-connected transistors operate equally by a method wherein the gaps between base contacts of parallel-connected transistors and emitter regions are respectively differentiated. CONSTITUTION:Within a semiconductor integrated circuit connected in parallel with at least two or more transistors formed on a main surface of semiconductor, the gaps between base contacts of respective parallel-connected transistors and emitters corresponding thereto are differentiated from one another. In order to make two transistors respectively including an emitter region 4e and another emitter region 4d operate equally, the gap between base contact 2d and emitter region 4d shall be set up to make base resistance R2=R1+R3+ hFE.R4 as the base current Id=Ie i.e. to increase the base resistance by the wiring resistance between contacts. In other words, the gap between base contact 2d and emitter region 4d have only to be wider than that between base contact 2e and emitter region 4e by the wiring resistance between contacts. The wider gaps may apply likewise to the transistors in the other emitter regions 4a, 4b and 4c.

Filed: 1985-01-16
Abstract: PURPOSE:To reduce cost and to widen a measuring range by providing electrodes on the two opposed surfaces of a composite dielectric material consisting of an org. material and inorg. material. CONSTITUTION:A pressure sensor body 1 is constituted by kneading resin powder of, for example, NBR or epoxy as the org. material and ceramic powder of, for example, barium titanate or strontium titanate as the inorg. material, molding the sheet-like composite dielectric material 2 and forming the electrodes 3, 4 by vapor deposition of aluminum on both sides of the material 2. The material 2 is deformed and the inter-electrode space and material density are changed when pressure is exerted to such body 1. The electrostatic capacity between the electrodes 3 and 4 is then changed in proportion to the pressure. The pressure measurement over a wide range with the relatively low pressure is thus made possible and since a pair of the electrodes 3, 4 are only provided to the material 2, the construction is simple and the inexpensive manufacture is thereby made possible.

Abstract: PURPOSE:Not only to substantially eliminate a leakage current to a substrate caused by a surge voltage but also to prevent the parasitic effect of a bipolar integrated circuit caused by the fluctuation of a substrate in potential by a method wherein a Schottky diode is interposed between a signal output terminal of a main circuit and a power source terminal. CONSTITUTION:An N<+>-type buried layer 102 is formed on a P-type semiconductor substrate 101 through diffusion, and furthermore an N<->-type epitaxial layer 103 doped with phosphorus is made to grow thereon. A P<+>-type insulation isolation layer 104 is so formed as to reach the substrate 101 from the surface, and an N<+> cathode electrode lead-out layer 107 is formed inside the isolated N<->-type epitaxial layer 3. A part of a silicon oxide film 109 formed on the surface is removed, and a Schottky contact window 111 and a cathode contact window 112 are formed. Aluminum is deposited on these windows 111 and 112 through sputtering for the formation of an anode electrode 114 and a cathode electrode 115, and the electrodes 114 and 115 are connected to a signal output terminal of a main circuit and a power source terminal respectively which are built in the same semiconductor chip. By this setup, even if a Schottky diode is biased in a forward direction, a leakage current is prevented from flowing to a substrate because the carrier of a current is electrons.
