摘要： A process for producing a MC-type conductive filler includes treating minute metallic particles with a coupling agent, preparing an oil phase of the coupling agent-treated minute metallic particles and a reactive substance A, the reactive substance A directly contacting the metallic particles. Then, an aqueous phase is prepared having a reactive substance B, which is capable of reacting with the reactive substance A, dissolved in water. Thereafter, the oil phase is dispersed in the aqueous phase to form a suspension. In situ reaction of the reactive substances A and B is then caused by applying heat to the suspension or adding a catalyst to the suspension. This forms a coating of a thermosetting insulating resin on the surface of the minute metallic particles. Alternatively, the reactive substance B may not be used. A MC-type conductive filler may also be made by immersing minute metallic particles in an affinity agent, immersing and dispersing the affinity agent treated-particles in an epoxy monomer and polymerizing the monomer to form an insulating polymer on the surface of the minute metallic particles.

摘要： A laminated type oxygen concentration sensor includes a laminated type oxygen concentration sensor element having a plate shape with a flange on a side surface thereof, and a housing in a tubular shape having an inclination seat inclined in a central axial direction thereof. The housing supports the laminated type oxygen concentration sensor element by contacting the inclination seat with the flange of the laminated type oxygen concentration sensor element at an outer circumference of the inclination seat. Since the sensor element is supported by contacting the flange with the inclination seat of the housing at the outer circumference of the inclination seat, the pressure per unit area imposed on the sensor element is minimized and cracking of the sensor element is prevented.

摘要： A superlattice avalanche photodiode with a mesa structure is provided, which enables to keep its noise characteristic low for a long time without decreasing the dynamic range for high-speed response. The photodiode has a semiconductor superlattice carrier multiplication layer, a first semiconductor electric-field buffer layers of a first conductivity type formed on one side of the carrier multiplication layer, and a second semiconductor electric-field buffer layer of a second conductivity type formed on the other side of the carrier multiplication layer. The photodiode further has a semiconductor light-absorbing layer of the second conductivity type formed on the second electric-field buffer layer. At least the light-absorbing layer constitutes the mesa structure. The first electric-field buffer layer is made of a central part and a peripheral part surrounding the central part. The peripheral part has a greater electric-field relaxation effect than that of the central part. The interface damage of the light-absorbing layer is restrained through the difference of the electric-field relaxation effect.

摘要： In an oxygen gas sensor having a variable electrical characteristic dependent upon ambient oxygen concentration, a ceramic holding member having a hole for holding a plate sensor sensor element is disposed in a housing with the element inserted into the housing. During sensor assembly, powder is filled under pressure in the housing between a pressurized member and the ceramic holding member. The ceramic holding member has an inclined surface descending directly from an upper opening end of the holding hole to form an obtuse angle between the sensor element and the inclined surface, so that the powder can flow on the inclined surface smoothly during the powder filling and powder compressing operations. By taking this construction it is possible to provide an oxygen concentration sensor with no cracking of the element and easy mounting of the sensor element to the housing.
