摘要： PURPOSE: To embody an exhaust emission control device by which the separation of HC is promoted after the temperature of a catalyst reaches the activating temperature, and the adsorbent performance is not deteriorated even if using in a short time is repeated. CONSTITUTION: An adsorbent 3 opened to an exhaust port 11 is fixed in an exhaust manifold 2 communicated with the exhaust port 11 of an internal combustion engine 1. An exhaust gas purifying catalyst 5 is arranged in an exhaust pipe 4 downstream from the exhaust manifold 2. A heater part 33 is integrally provided on the rear end of the adsorbent 3, and the heater part 33 is operated by a controller 7 when the catalyst 5 temperature detected by a temperature sensor 51 provided near the catalyst 5 reaches the activating temperature. Thus, the adsorbent 3 is quickly heated, and the separation of HC is promoted, and the HC is prevented from remaining in the adsorbent.

摘要： PURPOSE: To enable efficient adsorption of HC exhausted at the starting time of an engine by eliminating disturbance of moisture contained in exhaust gas. CONSTITUTION: A physical moisture separation and removal means, for instance, a cyclon moisture remover 1 is arranged on an upstream side of an HC adsorption agent 2, for separating moisture contained in exhaust gas by centrifugal force, and discharging it while bypassing the HC adsorption agent 2. A moisture absorption agent is not used at a position which is exposed to high temperature, so that stability and durability are improved.

摘要： PURPOSE:To improve use efficiency of a fuel by completely separately supplying a gaseous fuel and water which is necessary at the time of reaction. CONSTITUTION:A fuel cell is comprised of a means to supply a gaseous fuel from one side of a fuel electrode and a means to supply water in liquid-state which is necessary at the time of reaction from the other side of the fuel electrode. Methanol in gas-phase is supplied as a gas to a catalyst layer 4 of a fuel electrode from a gasified fuel supplying route 11. Meanwhile, water which is needed to decompose methanol is permeated through a cation-exchange membrane 3 from a water-supplying route 10 and supplied from the opposite side to the methanol supplied side. Methanol and water are thus supplied completely separately to the catalyst layer of a fuel electrode and reaction is carried out. As a result, even when the working temperature of the fuel cell is lower than boiling point of water, current density lowering owing to liquification of the fuel does not occur and a direct-type fuel cell with high use efficiency of the fuel is obtained.

摘要： PURPOSE:To perform torque detection with small variance by using stripped amorphous magnetic bodies which are formed at constant intervals on the surface of a plate on the same periphery of a rotary shaft and has plural values. CONSTITUTION:A torque converter 2 is coupled with the output shaft of a transmission 20. A plate 1 made of a nonmagnetic material is coupled by bolts 23 and 24 interposed between a crank shaft 22 and a converter 21. The twelve amorphous layers 2 which have a center angle of 25 deg. are formed on the surface of the plate 1 facing the side of the shaft 22 radially on the rotary shaft on the same circumference at constant intervals. End parts of the exciting magnetic pole piece and detecting magnetic pole piece of a torque sensor 3 are fixed tightly to the amorphous layers 2 and when torque is transmitted to the plate 1, a voltage is induced across the winding of the detecting magnetic pole piece and inputted to a differential amplifying circuit 6 to perform torque detection with small variance.

摘要： PURPOSE:To enable a driven part to be electrically accurately further finely controlled, by controlling an oil hydraulic circuit by the displacement of a piezo-actuator. CONSTITUTION:A housing forms in its inside a pressure transforming chamber 38 and a pressure oil chamber 39, and a driven part 2 is driven by a pressure from the pressure oil chamber 39. While fluid in the pressure transforming chamber 38 is transmitted to the pressure oil chamber 39 through a check valve 35, further a needle valve 34, which opens and closes a relief port 41 relieving the pressure in the pressure oil chamber 39 to the outside, operates so as to open and close by a difference between the pressure in the pressure oil chamber 39 and the pressure in the pressure transforming chamber 38. Further the pressure in the pressure transforming chamber 38 changes so as to be variably controlled in accordance with the displacement of a piezo-actuator 31. By this constitution, an electrically accurate further fine control can be performed.

摘要： PURPOSE:To improve response property of a liquid sensor, by supporting a substrate on which a film-type resistance is formed on a good heat-rotative supporting member through a heat-throttling member. CONSTITUTION:A supporting member 21 is composed of a metal of high thermal conductivity and low specific heat, such as Al, etc. Consequently, heat transferred from a film-resistance 7 through thermal insulators 23a, 23b as heat- throttling member is radiated into an air stream quickly from the member 21 of good heat radiative property. Namely, heat produced from the resistance 7, because of existence of the insulating members 23, 23b, is radiated to the air stream from the resistance 7 itself to a greatest extent and a portion also is transferred to the supporting member 21 through the members 23a, 23b. Consequently, heat transferred to the member 21 is stabilized quickly for improvement of responsivity of the flow-rate sensor.

摘要： PURPOSE:To reduce the error of a measuring flow rate by comparing a film type resistor with a temperature compensating resistor which have equal characteristics under the same condition by a comparator and feeding back the output of the comparator. CONSTITUTION:When an air flow rate is increased, the temperature of the film type resistor 7 is dropped, the resistance value of the resistor 7 is dropped, and then the ground voltage V1 of the resistor 7 is reduced less than the ground voltage VR of the temperature compensating resistor 8, the conductivity of a transistor (TR)94 is increased on the basis of the output of the comparator 93. When the air flow rate is reduced and the temperature of the resistor 7 is increased, the resistance value of the resistor 7 is increased, V1>VR is formed and the current is reduced. Consequently, the heating energy of the resistor 7 is reduced and the output voltage V0 of a voltage buffer 95 is simultaneously dropped. Consequently, the temperature of the resistor 7 is fed back so as to be fixed against the external temperature and the voltage V0 indicates the air flow rate.

摘要： PURPOSE:To prevent the deterioration of a sensitivity and a responsiveness of a sensor by providing a trap on the upstream side of a membrane type resistance for feeding back a calorific value so that a temperature of the membrane type resistance provided in a suction passage becomes constant, and settling a floating particle. CONSTITUTION:A membrane type resistance 6 provided in a suction passage is connected to a controlling circuit which is not shown in the figure, by a distributing pattern 22 vapor-deposited onto an insulating substrate 21, a calorific value is fed back, and a voltage is impressed so that a temperature of the membrane type resistance 6 becomes constant. A trap consisting of a wire rod 23 is formed on the upstream side of the membrane type resistance 6, and also on the almost same axial surface as the membrane type resistance, and a floating particle 24 is settled. In this way, the deterioration of a sensitivity and a responsiveness of the sensor is prevented.
