Abstract: In an electronic control apparatus, a connector mounted on a circuit board accommodated in a casing body constructed with top and bottom casings is partially exposed outside the casing body to be mated with an external connector. A sealant is interposed between the top and bottom casings, between the top casing and the connector, and between the bottom casing and the connector. A sealing part of at least one of the top and bottom casings has a substantially rectangular ring shape with rounded four corners. A sealing part of the connector faces two adjacent corners of the rectangular sealing part and one side of the rectangular sealing part directly connecting the two adjacent corners.

Abstract: An object of the present invention is to provide a highly-reliable combined heater. Heater 1 includes hot water pipe 1a for allowing hot water to flow therethrough, and metal pipe 1b that is coaxial with hot water pipe 1a and that is secured in contact with an inner peripheral surface of the hot water pipe.

Abstract: An electronic control device includes a multilayered flexible substrate and first to fourth spacers disposed in a casing. The multilayered flexible substrate, including first to third rigid substrate portions, is folded in a multilayered arrangement in such a manner that each rigid substrate portion is sandwiched between two spacers. The first rigid substrate portion is disposed at the lowest position to arrange a lowermost layer. The second rigid substrate portion is folded upward relative to the first flexible portion by 180 degrees to arrange an intermediate layer. The third rigid substrate portion is folded upward relative to the second flexible portion by 180 degrees to arrange an uppermost layer. The card edge connectors are laminated or layered with predetermined gaps and positioned in a case opening.

Abstract: An electric floor heating system, comprising an electric floor heating panel and a floor heating material formed by laminating integrally an upper material with a thickness of (d), a heat diffusing material with a thickness of (t), and a lower material, wherein the upper material thickness (d) and the heat diffusing material thickness (t) are set to fulfill relational expression (I):

Abstract: A spirally woven fabric as well as a prepreg and a rotary body each using the fabric therein is adapted for use as materials for high-speed rotary bodies such as flywheels for electric power storage. The fabric composed of interwoven warps and wefts is such that its warps are arranged in a spiral direction, and the warps positioned more outside in the radial (weft) direction have a higher specific elastic modulus in the warp direction than those positioned more inside in the radial direction whereby a rotary body made of the fabric is enabled to be rotated at a higher rotating speed without breakage of the wefts and consequent peeling-off between the warps.

Abstract: In order to improve product quality control through quantitative determination of a defect and quantitative judgement of the quality of a product, an alternating current is applied to a standard product coil into which is inserted a standard object, and to a test object coil into which is inserted a test object, and eddy currents are measured by means of a bridge circuit. If the test object coil is at a location removed from a flaw, the bridge circuit output voltage is zero, while if the test object coil is at the location of the flaw, a predetermined voltage is output. A determination of torsional breakage torque of the shaft inspection is carried out by correcting the output voltage for dependence on the cross sectional area ratio of the test object relating to the cross sectional area of the coil and for the influence of flaw size depending on the location.
