摘要： Air fuel ratio sensor for use in an exhaust gas purification system for an internal combustion engine. The sensor has an outer and inner cover 12 and 13 for protection of lead wires 16, 18 and 19 to a detecting element 3 and a heater 5 of the sensor, a rubber seal for 2 for obtaining a sealing between the covers and the lead wires and a water repellent filter 36 for obtaining a seal between the inner and outer covers 12 and 13, while keeping an air ventilation capability of the space inside the covers. For receiving the lead wires 16, 18 and 19, the seal 2 is formed with holes 20 such that the minimum thickness between the holes and the minimum thickness between the hole and an outer surface of the seal is 1 mm or more. A crimping of the outer cover 12 is done so that a deformation of the seal 2 in a range between 10 to 20% of the outer diameter is obtained. A crimping of the outer cover 12 is further done at a first section 12A at a larger force for fixation of the outer cover 12 to the inner cover 12 and at a second section 12B at a smaller force for holding the water repellent filter 36 between the outer and inner covers. In the crimping, the crimping at the first section is completed simultaneously or earlier from the completion of the crimping at the second section.

摘要： An air-fuel ratio sensor of a limit current type is used for an air-fuel ratio feedback control. When the air-fuel ratio sensor is in a semi-activated state, the air-fuel ratio sensor is driven into an electromotive force generating mode by a current externally applied thereto thereby to shift an electromotive force changing point so that an air-fuel ratio at which the electromotive force changes stepwisely is shifted from the stoichiometric ratio point to a lean zone. When the air-fuel ratio sensor is in a completely activated state, the air-fuel ratio sensor is applied with a voltage to produce a limit current varying with an air-fuel ratio so that a feedback control is performed based on the advanced control theory by using a linear current output characteristics.

摘要： A gas concentration detector comprises a plate sensor element including a sensing action and a signal output section. A flange section is formed between the sensing section and the signal output section so as to protrude in the lateral direction thereof. A cylindrical housing has an inside space for receiving the sensor element. Powder is disposed in the inside space of the cylindrical housing at a predetermined position adjacent to the flange section so that the sensor element is airtightly fixed to the housing by applying a pressing force on the powder. Furthermore, a cross-sectional area of the signal output section is larger than a cross-sectional area of the sensing section.

摘要： Magneto-optical disk recording and reproducing devices and actuators and distance detectors for use therewith are disclosed. The mageneto-optical disk device comprises, in addition to the usual elements, a bimorph type actuator or an electromagnetic actuator for driving the magnetic head of the magneto-optical disk device. The bimorph actuator has a metallic shim whose width varies with respect to the longitudinal distance inversely porportional to the normal function of the first or the second free natural vibration mode. Alternatively, the bimorph type actuator have a recess formed on a bimorph element to expose a piezoelectric crystal which outputs a voltage corresponding to the acceleration of the vibration of the actuator; the driver circuit of the actuator reduces the driving voltage when the frequency of the voltage generated at the recess comes into the neighborhood of a higher resonance frequency of the actuator. The optical distance detector comprises a light-emitting diode and a pair of photodiodes which detects the amount of light incident thereon after being reflected at a surface of an object the distance to which is measured. The geometric parameters of the photodiodes are selected in such a manner that the output of a first photodiode decreases as the measured distance increases while the output of a second photodiode increases as the measured distance increases. Thus, the normalized differential output of the two photodiodes, from which the measured distance is determined, varies substantially linearly with respect to the measured distance. In preferred forms, the photodetectors have stepped concentric configurations so that small distances can be measured accurately and efficiently.

摘要： A circuit board comprising: a core material made from magnesium, a magnesium alloy, or a magnesium-based composite material, and an electric circuit formed on the core material. A process for producing the circuit board comprises the steps of (1) forming an electrodeposition-painted coating on such a core material, (2) forming a polyimide resin coating on the electrodeposition-painted coating, (3) forming a via hole extending through the resin coating to the underlying electrodeposition-painted coating, (4) etching and removing the electrodeposition-painted coating in the region exposed in the bottom of the via hole while masking the other region with the resin coating thereby extending the via hole to the core material, (5) forming a metal film on at least a free surface of the resin coating and an inner surface of the extended via hole, and (6) etching the metal film by using a photoresist mask to form a conductor layer having a predetermined pattern.

摘要： A vibration damping device is comprised of first and second axially spaced end housings adapted to be mounted on spaced apart structures, and has a tapered intermediate member mounted on the second housing converging toward an open end of the first housing. A piston is mounted on an end of a rod which is connected to the first housing and extends through a bore formed in the intermediate member and forms a restricted flow orifice extending between the spaced apart housings. A pair of elastomeric sleeves extend between the intermediate portion and the piston and the first housing to form a pair of fluid chambers connected by the orifice. An elongated electrode preferably contacts an electrorheological fluid flowing between the chambers through the orifice. The tapered intermediate member is nestable within the interior of the first housing when the device is in a jounce condition and the tapered piston is nestable within the interior of the intermediate member when the device is in a rebound condition to provide a compact damping device without sacrificing stroke length, and which enables the length of the electrode to be independent of the stroke length.
