The silicon diaphragm assembly has a circular pressure sensitive diaphragm, on the surface of which are diffused piezoresistors and conducting paths. The covering member composed of borosilicate glass has a circular well formed therein. On the surface of the silicon diaphragm assembly on which the piezoresistors and the conducting paths are diffused, a passivating layer of silicon dioxide is deposited. Further on the passivating layer, a conductive layer is formed by, for example, evaporating silicon. And the glass covering member is bonded on the silicon diaphragm assembly by anodic bonding. Namely, the silicon diaphragm assembly and the glass covering member are heated up to a certain high temperature and a relative high voltage applied across the conductive layer of the silicon diaphragm assembly and the glass covering members.

摘要： An electronic device for an automobile is roughly divided into individual parts and control circuit elements which are mounted in a casing divided into two compartments, according to the present invention. The individual parts are arranged in one compartment and are covered with silicone rubber to improve their water resistance. The control circuit elements are arranged in the other compartment and are covered with a silicone gel to prevent any stresses acting upon the control circuit elements, such as ICs, and provide these elements with moisture resistance. The control circuit elements are bonded by high-temperature solder to improve their heat resistance, but the individual parts are bonded by eutectic solder.

摘要： A liquid level detecting apparatus comprises a thermistor adapted to generate heat by current flowing therethrough, wherein the liquid level is sensed by detecting a current value at the thermistor which varies in dependence on a variation in temperature of the thermistor, which temperature in turn varies in dependence on whether the thermistor is immersed in the liquid or exposed to air. A relay coil is provided in series to the thermistor and disposed within a casing together with the latter so that the variation in temperature of the liquid may be transmitted to the relay coil, wherein the variation in the current value at the thermistor caused by the temperature variation of liquid is corrected by the variation of the resistance of the relay coil.
