摘要： A pressure detection apparatus has a pressure-sensitive resistor whose first resistance varies according to pressure and a change of its own temperature, a temperature-sensitive resistor which has a same resistance-temperature coefficient as the pressure-sensitive resistor and whose second resistance varies according to the change of the temperature, a current source supplying first and second constant-currents to the pressure-sensitive and temperature-sensitive resistors respectively, and a pressure signal generation output section. The current source adjusts the first and second constant-currents so that when the pressure is an initial pressure, a reference first voltage appearing across the pressure-sensitive resistor and a reference second voltage appearing across the temperature-sensitive resistor become equal to each other. The pressure signal generation output section outputs a first voltage signal corresponding to the pressure on the basis of a difference voltage between a first voltage of the pressure-sensitive resistor and a second voltage of the temperature-sensitive resistor.

摘要： A mass flow sensor includes a semiconductor substrate 1, an insulating thin film 2, heaters 311 and 312, temperature measurement resistors 321 and 322, and a protective layer 4. The heaters 311 and 312 are formed on the surface of the insulating thin film 2, and are provided adjacently such that the heater 311 is provided upstream the heater 312 and the heater 312 is provided downstream the heater 311. A cavity 5 is formed below the heaters 311 and 312, and the heaters are thermally insulated from the remaining portion of the semiconductor substrate. The temperature measurement resistors 321 and 322 are formed on the top surface of the insulating thin film 2, and are provided at opposite sides of the heaters 311 and 312, such that the resistors are aligned with respect to the flow passage of a fluid. In the mass flow sensor and the mass flowmeter including the sensor, the flow rate and flow direction of a fluid can be detected by means of merely the heaters 311 and 312, which are active elements. Therefore, the sensor and the flowmeter exhibits high-speed response with respect to change in the flow rate of the fluid.

摘要： Between a gas sensing layer (4) and a base member (15) composed of a silicon substrate (2) and an insulating coat layer (3), there is formed an adhesion layer 7, to improve the adhesion therebetween, and to prevent separation. The gas sensing layer (4) and sensing electrodes (6) are electrically connected by abutment of a confronting surface (61) of sensing electrodes (6) confronting the gas sensing layer (4) and sides surfaces of the sensing electrodes on both sides, on the gas sensing layer (4), and accordingly the gas sensor properly senses an electric characteristic of the gas sensing layer (4) varied in accordance with a concentration variation of a specified gas. Furthermore, the sensing electrodes (6) are in contact with the gas sensing layer (4), but the sensing electrodes are not in contact with the adhesion layer (7). Therefore, the adhesion layer (7) need not be a complete insulating layer, and it is possible to use, as the adhesion layer, an incomplete insulating film or a conductive film, so that options of the adhesion layer (7) are increased.

摘要： The object of the present invention is to provide a gas sensor in which a gas detection element is mounted on a wiring substrate; in which a protective cap having gas inlets formed therein is attached to the wiring substrate; and which has a structure capable of effectively preventing emanation of gas from the wiring substrate and the protective cap. A gas sensor comprises a gas detecting element on a writing board where a protective cap with air vents is mounted. The sensor effectively prevents a gas from emanating from the wiring board and the protective cap. The wiring board where a plurality of gas detecting elements (8,9) are to be mounted is formed of a ceramic wiring board (2) excellent in heat resistance. The protective cap (3) having air vents (31 to 39) is formed of a metal excellent in heat resistance. The metal protective cap (3) is fitted to the ceramic wiring board (2) instead of using adhesive. In this way a gas sensor (1) is manufactured. Adoption of such a structure enables suppression of the gas emission from the ceramic wiring board (2) and the metal protective cap (3) effectively during the manufacturing step or in use of the gas sensor (1) attached to a car, thereby preventing lowering of the gas detection accuracy or early deterioration of the gas detecting elements (8,9).
