    摘要： A flow-rate detecting device for a heat-sensitive type flow sensor having high reliability. The device includes a planar substrate having first and second through-holes formed therein in juxtaposition with each other, an insulative supporting film formed over one major surface of the substrate so as to cover the through-holes, a fluid temperature measuring resistor formed by a heat-sensitive resistor film deposited at a location of the first through-hole on the supporting film oppositely to the substrate, a heat generating resistor formed of a heat-sensitive resistance film deposited at a location of the second through-hole on the supporting film oppositely to the substrate, an insulative protection film deposited so as to cover the fluid temperature measuring resistor and the heat generating resistor, and a reinforcing film provided for the fluid temperature measuring resistor. The reinforcing film is not provided for the heat generating resistor. Flow rate or alternatively flow speed of a fluid is measured by taking advantage of phenomenon of heat transfer to the fluid from the heat generating resistor.

    摘要： A supporting film is formed over an entire front surface of a base material, a heating resistor composed of a platinum film having a predetermined pattern is formed on the supporting film, and a protecting film is formed over an entire surface of the supporting film so as to cover the heating resistor. A heating structure having a diaphragm construction is constructed by forming a cavity under a region where the heating resistor is formed by removing a portion of the base material so as to extend to the supporting film from the rear surface side of the base material. The supporting film and the protecting film are each constituted by a silicon nitride film having an index of refraction of less than 2.25.

    摘要： A flow rate detecting element measuring the flow rates of various fluids, particularly the intake air of an internal combustion engine. The flow rate detecting element has a thin film layer including a support film and a protective film on one surface of a flat substrate, a heating resistance section and a comparative resistance section thermosensitive resistor having patterns and located between the support film and the protective film. The flat substrate has a recess which penetrates the flat substrate in the thickness direction thereof and facing the heating resistance section and the comparative resistance section. A fluid flow passage communicates with the recess which faces the comparative resistance section for fluid flow into the recess. Flow rate or velocity of a fluid can be measured accurately using the heating resistance section according to the fluid temperature reported by the comparative resistance section.

    摘要： An optical disk adapted to resist moisture absorption, warping and static charge is disclosed. The disk includes an SiO.sub.2 film coating over at least a portion of a disk substrate. Additionally, an optical disk having a magnetic film protected by a fluorocarbon polymer is disclosed. Either of such disks can be used individually or, alternatively, they can be used in a laminated structure having two disks laminated in a face-to-face relationship. The laminated structure can be covered with SiO.sub.2 film.

    摘要： To obtain a flow sensor having excellent responsibility, sensitivity and reliability and high flow detection accuracy by suppressing the deformation of a diaphragm, first additional patterns are formed on a side opposite to connection patterns of a heating element so that thin film patterns formed on the diaphragm become almost symmetrical, thereby suppressing the deformation of the diaphragm caused by internal stress between a base film or protective film and a platinum film forming the thin film patterns and the differences of mechanical or thermal properties therebetween.
