摘要： PURPOSE:To obtain high sensitivity by providing a gas sensing part comprising a semiconductor or metallic porous body with numerous narrow holes formed in a predetermined direction and a pair of electrodes wherein a direction perpendicular to a lengthwise direction of the narrow holes is a current path. CONSTITUTION:A gas sensing part 1 comprising porous silicon is supported on an insulating substrate 2. A heater 3 is attached to a rear of the insulating substrate 2, wherein gas absorption/desorption is facilitated by applying heat with this heater 3. A pair of comb-shaped electrodes 4a, 4b are provided on an upper face 1a of the gas sensing part 1 comprising porous silicon. The comb- shaped electrodes 4a, 4b are formed by evaporating for example a thin metal film on the upper face of the porous silicon. By thus providing a pair of comb- shaped electrodes 4a, 4b on the upper face 1a of the porous silicon, a current path flowing between the electrodes 4a, 4b is in a direction approximately perpendicular to a formation direction of narrow holes on the porous silicon, so chat gas absorption is sensitively influenced.

摘要： PURPOSE:To prevent stripping of lead wires by forming a pair of electrodes opposite to part of both surfaces of a moisture sensing element, using one of these also as a heting electrode during cleaning and forming the lead parts up to the terminal of the moisture sensing element. CONSTITUTION:A pair of electrodes 10, 10' are formed opposite to one end part of both surfaces of a moisture sensing element 9 consisting of an oxide sintered body. One of these two electrodes is used also as a heater which causes resistance heat evolution. A pair of lead parts 11, 11' are formed on the same surface of the element 9 from the electrode 10 up to the other end of the element 9. Similarly, one piece of a lead part 11'' is formed from the electrode 10' up to the other end part of the element 9. Lead wires 12, 12', 12'' are connected respectively to the terminals of the lead parts 11, 11', 11''. Since the connected parts of the lead wires are through the lead parts from the heating part at the cleaning, the influence from the heating part is less and the stripping of the lead wires in the connected parts is prevented despite reiteration of cleaning.

摘要： PURPOSE:To obtain a sensor for detecting gas which is highly sensitive, can maintain sensitivity for a long time, and can detect reducing gas and noncombustible gas providing a heater etc. for heating a gas-adsorption film. CONSTITUTION:Electrodes 2a and 2b are provided on both surfaces of a crystal vibrator plate 1 and gas-adsorption films 3a and 3b are applied to the surface of the electrodes 2a and 2b. Further, flat-plate shaped ceramic heaters 8a and 8b are installed in parallel with the vibration plate 1 using a lead frame 9 for support which is connected to a lead pin 6c fixed to an insulation support stand 7. When gas is adsorbed to the adsorption films 3a and 3b, the resonance frequency of the vibration plate 1 changes according to the weight of gas, thus detecting gas. At this time, by heating with the heaters 8a and 8b, the adsorption/desorption of gas become reversible, thus preventing gas from being adsorbed and hence sensitivity from being reduced regardless of repeated measurement.

摘要： PURPOSE:To detect an SF6 cracked gas in a high sensitive and high accurate manner under the condition of temperature and pressure in a gas insulated breaker by canceling a variation portion due to the temperature and pressure of a main detecting sensor by a compensating circuit. CONSTITUTION:A quartz oscillator type gas sensor (main detecting sensor) 4 is installed in a gas-permeable vessel 3, and a quartz oscillator type gas sensor (temperature referring sensor) 8 is sealed in a pressure-proofing hermetically sealed vessel 7 together with am SF6 gas. In addition, a quartz oscillator type gas sensor (pressure referring sensor) 13 is sealed in a bellows type vessel 12 whose capacity varies according to internal-external pressure variations, together with the SF6 gas. In succession, each of driving circuits 17, 18 and 19 converts those of characteristic variations of the sensor 4, the sensor 8 due to an ambient temperature change, and the sensor 13 due to temperature and pressure changes into respective electric signals, outputting them to a compensating circuit 23 in which compensation and operation take place with these signals after each waveform, amplitude, dynamic range or the like of these inputted signals are set in order once, and then a cracked gas content signal 24, a temperature signal 25 and a pressure signal 26 are all outputted.

摘要： PURPOSE:To obtain a highly reliable moisture sensor by making a copolymer layer of poly methylglutaminate and polyurethane hard near a melting temperature on an inorganic insulating substrate to laminate the same copolymer layers in such a manner that they can be hardened by heat. CONSTITUTION:SiO2 and SiN3 are laminated on an Si substrate 1 by a CVD method. A copolymer of poly methylglutaminate and polyurethane is diluted by demethylformamide DMF and applied on the substrate in rotation and hardened near a melting point to form a ground layer 4. Then, an Au electrode 5 is deposited on the layer and the same copolymer is diluted to 50% by volume by DMF and applied on the electrode 5 to form a moisture sensitive film 6 by drying at 80 deg.C. An Au electrode 7 is deposited on the film 6. The work is separated into elements with a dicer. The moisture sensor thus obtained provides a higher response speed and a smaller hysteresis and allows combination with an Si element in a process. It also has a long-time reliability with a better adhesion to the substrate.

摘要： PURPOSE:To enhance durability by preventing the heat shock destruction of a protective layer at the time of high speed printing by a method wherein the constitutional material of the protective layer formed on a heat generating resistor consists of two kinds of materials and the component ratio of two kinds of materials is changed over three layers upwardly from the surface of a resistor. CONSTITUTION:A glaze layer 2 is formed on a ceramic substrate 1 and a heat generating resistor layer 3, an electric conductor layer 4 and protective layers 5-1, 5-2, 5-3 are successively laminated on the glaze layer 2. When the materials constituting the protective layers are Al2O3 and SiO2, each of the layers is set to a thickness of 5,000Angstrom or more and the composition ratios of the respective layers are set so that the first layer 5-1 in contact with the resistor layer consists of 10-30mol% of Al2O3 and 90-70mol% of SiO2, the intermediate layer 5-2 consists of 40-60mol% of Al2O3 and 60-40mol% of SiO2 and the uppermost layer 5-3 consists of 70-90mol% of Al2O3 and 30-10mol% of SiO2. By this method, the protective layers are not destructed by a heat shock even when high speed printing is performed and the life of a thermal head can be extended.

摘要： PURPOSE:To enhance not only heat efficiency but also abrasion resistance, in a thermal head consisting of a membrane heat generating resistor and the protective layer formed on said resistor, by forming the protective layer from a membrane having specific density. CONSTITUTION:In a thermal head wherein a membrane heat generating resistor 2 is formed on a substrate 1 and a protective layer 4 is formed on said resistor 2, the protective layer 4 is formed of a membrane and the density thereof is set to 75-95% of the theoretical density of the material quality of the protective layer 4. The membrane material of the protective layer 4 is pref. selected from Al2O3, SiO2, ZrO2, Ta2O5, Si3N4, AlN and Ti3N4. When the density of the protective layer 4 is low as mentioned above, a void is generated in the protective layer 4 and the heat conductivity of this part is extremely inferior in the same degree as air and the heat conductivity of the protective layer 4 becomes low as compared with a conventional dense protective layer. As a result, the diffusion of heat energy in a lateral direction is reduced and the printing efficiency of recording paper is enhanced.
