IPC: G02B6/255
Filed: 1995-06-02
Abstract: PURPOSE: To obtain a resilience and tensile strength and to miniaturize the reinforcing structure by injecting a specific coating resin into the space between a thermal shrinkage type protective tube and a fusion spliced part and thermally shrinking this tube to cure the coating resin. CONSTITUTION: The thermal shrinkage type protective tube 3 is put on the fusion spliced part 2 between right and left optical fiber coating parts 1, and the coating resin 4 of a thermosetting type or UV curing type mixed with a tensile strength fiber, for example, carbon fiber and glass fiber, is previously injected into the space between this protective tube 3 and the fusion spliced part 2 (and optical fiber coating parts 1). This coating resin 4 may be a resin tube having a low m.p. The entire part of such reinforcing structure is heated, thereby, the protective tube 3 of the thermal shrinkage type is shrunk. Further, the coating resin 4 is simultaneously cured as well when the coating resin 4 is of a thermosetting type. The bubbles intruding into the injected coating resin 4 are, therefore, squeezed outside together with the excess resin.  The reinforcing part 10 is formed within the protective tube 3 in such a manner.

Filed: 1989-05-30
Abstract: PURPOSE:To achieve good mass productivity and stabilize quality such as electron radiating property of an electron cathode tube by forming a sintered layer of a nickel powder containing scandium oxide on a metal substrate and forming an electron radiating layer on the sintered layer. CONSTITUTION:Scandium oxide 6b is added to a nickel powder 6a, the resultant powder is added to a specific organic solvent to give a suspension, and then the suspension is sprayed to a metal substrate 1. Then, by thermal treatment in hydrogen or vacuum atmosphere, a sintered layer 6 of a nickel powder 6a containing a scandium oxide 6b is formed on the metal substrate. An electron radiating material is applied to the sintered layer 6 by a method for example spraying. Due to this simple process, productivity is improved. Owing to the sintered layer, the layer has sufficient porosity and thus a reductive metal is easily diffused to the electron radiating layer 5 from the metal substrate 1 and dispersion of initial electron radiating property is decreased.

Title: Catalytic combustion type gas sensor output circuit fitted with operational amplifier
Inventor: MATSUNO MASARU
IPC: G01N27/16
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To enable the response of a signal within a wide range without using an expensive circuit device by adding a floating return potential supply circuit shifting the voltage of a signal source to the responding range of an operational amplifier. SOLUTION: A floating return potential supply circuit C is constituted so that the collector voltage VF of the transistor T connected to the output side of the circuit C is allowed to negatively feedback to the non-reversal input terminal of an operational amplifier Ac. By this circuit C, the collector voltage VF is kept so as to become equal to the stable reference voltage element voltage VFO (e.g; 1.2V) formed by a reference voltage element Z. Therefore, the operational center point of the operational amplifier Ac of an amplifying stage is always raised by 1.2V of the reference voltage element voltage VFO and, as a whole, the operational reference voltage to amplifier circuit power supply voltage VA is set to about 2V.  As a result, the voltage amplification in the non-sensitive band in the vicinity of 0V-1.5V of the operational amplifier Ac becomes possible and a signal can be allowed to respond within a wide range.

Abstract: PURPOSE:To obtain a small-sized resistor module whose surface temperature is low by burying a thin-wall tube of high thermal conductivity which is formed by winding a resistive wire, in a cement mortar, and enabling the forced draft from the outside into the inside of the thin-wall tube. CONSTITUTION:A resistor module 20 is constituted, by arranging, in a metal casing 9, one or more ceramic tubes 21 buried in cement mortar 10.

As a result, the temperature of resistive wire does not become high, and the temperature rise of the resistor module 20 can be prevented. Thereby, the temperature rise of the resistor module can be restrained and the miniaturization of the device is enabled.
