摘要： PURPOSE:To enhance the efficiency of a fuel battery by providing a water absorptive layer consisting of a hydrophile material on the surface of a groove for supply of oxidating agent in such an arrangement as along the longitudinal of this groove, and at its end face, providing a water gathering member consisting of hydrophile material equipped with a passage or circulation of the oxidating agent. CONSTITUTION:When a fuel battery is driven, water is produced at an air electrode as a result of reaction. This water becomes drops in a groove 11 provided in a separator 10, wherein it is absorbed immediately in a water absorptive layer because it exists on the surface of the groove 11, so that it is prevented that the large particles generated from the water from choking the groove. The water absorbed in this water absorptive layer 13 is carried to the end of the separator by 10 by means of capillary phenomenon. Because this water absorptive layer 13 is in contact with a water collecting member 15, the water is transferred to the member 15 to move downward by its own weight and by capillary phenomenon to then be exhausted to outside the system from a drain 31. Because the water produced at the air electrode does not stagnate in oxidating agent supplying groove but is exhausted quickly, the performance of the battery as a fuel battery will not drop with the initial performance well maintained for a long period of time.

摘要： PURPOSE:To improve the precision of flow rate detection by reducing the heat loss of a substrate where a film type resistance is formed. CONSTITUTION:The film type resistance 6 is fixed at a holding part 7a across a heat insulator 13. In this case, both surfaces of the heat insulator 13 are coated with an adhesive. On the other hand, a wiring sheet 14 connected to a lead wire is provided on the holding part 7a. Thus, the film type resistance 6 is fixed at the holding part 7a and then wiring 15 is provided by wire bonding between the pad part 62b of the resistance 6 (temperature dependent resistance pattern 62) and the pad part 14a of the wiring sheet 14 of the holding part 7a. The connection part between the resistance 6 and holding part 7a is of similar constitution. The diameter of the bonding wiring 15 is small, so the heat loss due to the wiring is reduced. The heat insulation effect of the resistance is therefore increased. Further, the heat insulator 13 is made small within a range wherein the holding force of the resistance 6 is held sufficiently to reduce the heat mass of the heat insulator 13, and consequently the response speed of an air flow rate sensor is increased and the detection precision is improved.

In this case, a vibrator 9 is provided on the upstream side of the membrane type resistance 6 and also on the same axis as the membrane type resistance 6, and vibrated by an oscillator 11. In this way, it is prevented that dust adheres to the membrane type resistance 6, and a response speed and a sensitivity of the air flow rate sensor can be improved.

摘要： PURPOSE:To eliminate two fixed resistances composing a bridge while improving the strength by junctioning a plurality of two kinds of metal filamentous bodies alternately in series on a substrate as thermocouples to arrange the first junction group at the upstream of the electric heater and the second junction group at the downstream thereof. CONSTITUTION:For example, this apparatus is used to measure the flow rate of a sucked air of the engine. A plurality of two kinds of platinum thin film filamentous bodies M1-M100 and N1-N100 are junctioned alternately in series on a flow rate detection substrate 9 as thermocouple. As air flows parallel with the detection surface 9 in the direction of the arrow, the air heated with a heater 17 affects the second junction group 10B downstream but not the first junction group 10A upstream, which causes a temperature difference between both the junction groups 10A and 10B. Drawing the temperature difference direct as an electromovice force signal eliminates the need for drawing the temperature as resistance change to obtain it as power variation through a bridge circuit as in the past.

摘要： PURPOSE:To ensure a sufficient durability against vibration or the like while preventing the lowering of the response by making thin the part for securely holding a semiconductor chip of a substrate of a sensor provided in a passage to redue the heat capacity of the sensor section. CONSTITUTION:A fluid passage 23 is formed on a casing 22 at a sensor section arranged in an air passage for measuring the flow rate of sucked air (a) of the engine and a ceramic substrate 33 is fixed between casings 22A and 22B while four supports 34-37 projected as ramified from the substrate 33 are made thinner than the periphery 38 thereof to fix semiconductor chips 31 and 32 on the parts. With such an arrangement, a greater strength is achieved than when the substrate is made thinner as a whole while thermally, the quantity of a heater heat deprived of by the ceramic substrate from the semiconductor chip 32 and the quantity of heat transmitted to a gas from the ceramic substrate can be reduced to enhance the response with a less heat capacity.

摘要： PURPOSE:To improve durability and response, by providing temperature detecting elements at positions, which are close to or separated from a heater on a semiconductor chip respectively. CONSTITUTION:A heater 31 having a diffused resistor is formed at a position, which is slightly deviated to the downstream side on a semiconductor chip 30. A temperature detecting element 32 is formed at a position, which is separated to the upstream side from the heater 31 on the chip 30. A temperature detecting element 33 is formed at a position, which is close to the heater 31 on the downstream side on the chip 30. The heat yielded by the consumption of power in the heater 31 is transmitted to the air flow in a path 21 and to a silicon substrate. The heat conductions of the elements 32 and 33 from the heater 31 are largely different. The effects of heat received from the air flow are also largely different. Therefore, the temperatures can be made to have largely different values. Thus the flow rate can be detected highly accurately.

摘要： PURPOSE:To improve durability to oscillation, etc. and to provide a detector having excellent responsiveness by forming a flow rate detecting element on the surface of a semiconductor chip and disposing the semiconductor chip in a casing in such a way that the surface thereof has an acute angle to the flow direction of fluid. CONSTITUTION:A casing 11 is disposed in parallel with the flow of fluid in the intake conduit of an engine, and a sub-casing 16 having a semiconductor chip 17 is disposed in the passage 13A thereof. A fluid detecting element is adhered to the surface 17A of the chip 17 and since the element is set at an acute angle to the flow direction of the fluid, the flow of the boundary flow on the surface 17A is stabilized with decreased stripping flow, by which the accuracy of measurement is improved. A diode and resistor constituting the fluid detecting element are not wires and therefore there is no possibility of a disconnection and the durability against oscillation, etc. is high. A technique for manufacturing semiconductor is applicable for fine working of the fluid detecting element, by which the thermal capacity is decreased and the responsiveness is improved.
