Abstract: A glow plug (1) provided with heater (2); tubular main metal shell (4) with shaft hole (43); conductive member (3) extending in the shaft hole toward a rear end side GK; metal terminal member (5) with one part (55) positioned in the shaft hole and another part (56) protruding from a rear end (48) of the main metal shell toward the rear end side GK, the terminal member including an enclosing portion (51) opened toward a front end side GS housing a rear end portion (32) of the conductive member and having electrical continuity with the rear end portion, the terminal member being disposed in the shaft hole while spaced apart from an inner peripheral surface 43m of the main metal shell; and sealing member (7) made of an insulator and airtightly sealing and insulating between the inner peripheral surface and the terminal member in the shaft hole.

Abstract: [Object] To provide a glow plug such that corrosion of connecting surfaces of a conductive member and a terminal member is suppressed, and a method for manufacturing the same.

Abstract: The invention presents a method for manufacturing an IC card with a built-in battery where the seal of the battery does not breakdown during a heating and laminating process. The manufacturing method for the IC card of the invention includes accommodating a thin type battery 1 in a cavity 79 formed by overlaying an inner sheet 73 and a first oversheet 74 on a core sheet 72 having a penetration pole 79a. A second oversheet 75 covers the cavity 79, and a spacer 25 is inserted between a seal section 11 of the thin type battery 1 and second oversheet 75. Pressure and heat are applied to mutually adhere the sheets, wherein the pressing force is applied to the seal section 11 by way of the spacer 25.

Abstract: A non-resonance type knock sensor is provided which comprises a support member having a main body portion in the form of a hollow post and a radially outward flange portion at an axial end of the main body portion, the main body portion having an abutment at an outer circumferential periphery thereof, a piezoelectric element having a hole through which the main body portion extends and placed on the flange portion, a weight having a hole through which the main body portion extends and placed on the piezoelectric element, and an elastic device disposed between the abutment and the weight to produce an elastic force for pressing the weight and the piezoelectric element against the flange portion and thereby fixing the weight and the piezoelectric element to the support member.

Abstract: In a lithium cell using lithium foil or lithium alloy foil as an anode active substance, the main surface of an anodic current-collecting plate in direct contact with the lithium foil or the lithium alloy foil is roughened by laser machining.

Abstract: A knock sensor comprises a sensor body having a metallic shell including a cylindrical portion and a flange portion formed at an end of the cylindrical portion, an annular piezoelectric element fitted around the cylindrical portion and an annular weighting member fitted around the cylindrical portion to hold the piezoelectric element between the weighting member and the flange portion, and a resin-molded sensor casing arranged circumferentially around the sensor body. The resin-molded sensor casing includes a weighting portion located nearer to the weighting member than to the piezoelectric element with respect to an axial direction of the cylindrical portion, and at least the weighting portion of the resin-molded sensor casing is made of a resin containing at least one of metal powder and metal oxide powder and has a density of 2.0 g/cm3 or higher.

Abstract: A knocking detecting sensor for detecting knocking generated in an internal combustion engine includes a vibration detecting element, a terminal, a terminal holder, a casing and a sealing member. The vibration detecting element detects vibrations due to knocking. The terminal having a first and a second ends, the first end being connected to the vibration detecting element so as to take out an output therefrom. The terminal holder integrated with the terminal so as to hold it. The casing houses the vibration detecting element and the terminal holder, the casing having a terminal through-hole for externally protruding the second end of the terminal. The sealing member is arranged so as to surround the terminal between said terminal holder and the casing to prevent fluid from leaking into the inside of the casing from the terminal through-hole. Such a sensor structure assures airtightness of the casing and easiness of wiring the detecting element to the terminal.
