Abstract: A connection structure for connecting a connection mold to a fixed member, wherein a connection member which is connected to the fixed member to surround the connection mold is provided, the fixed member and the connection mold are provided with first position restraining means arranged to be slid from a predetermined direction X so as to be engaged to the fixed member and the connection mold in order to prevent mutual movement between the fixed member and the connection mold, and the fixed member and the connection member are provided with second position restraining means arranged to be slid from direction Y perpendicular to the direction X so as to be engaged to the fixed member and the connection member in order to prevent mutual movement between the fixed member and the connection member in a state where the connection mold is surrounded.

Abstract: A relay device 10 between relative rotating members has a flexible flat cable 13 wound in a spiral shape and arranged in a ring space K between sleeve-shaped members (an inside cylindrical portion, an outside cylindrical portion) 11a, 12a relatively rotating on inner and outer sides. The sleeve-shaped members 11a, 12a are electrically connected to each other through the flexible flat cable 13. The flexible flat cable 13 is constructed such that at least one end portion (an inner circumferential end portion, an outer circumferential end portion) 13a, 13b of the flexible flat cable is held in one of the sleeve-shaped members 11a, 12a through a holding member (an inner circumferential end holding portion, an outer circumferential end portion) 13g, 13h and a direction of the flexible flat cable is changed outward from one of the sleeve-shaped members 11a, 12a through a bent portion 13e, 13f bent at a predetermined angle.

Abstract: A housing and a rotor are electrically connected to each other by the flexible flat cable accommodated in an annular space formed between the housing and the rotor; an opening portion of a carrier disposed in the annular space and having a C-shape in a plan view is formed to allow an inversion portion of the flexible flat cable to pass through; and a lubricating members are provided for the sliding surfaces of the carrier.

Abstract: A discharge tube which assures stabilized discharging, is reduced in overall size and easy to manufacture is disclosed. The discharge tube comprises a cylindrical envelope made of an insulating substance, discharge gas enclosed in the envelope, and a pair of discharge electrodes disposed in an opposing relationship to each other at the opposite ends of the envelope. The the discharge electrodes are formed as parallel plate electrodes wherein faces thereof facing the inside of the envelope extend flat and in parallel to each other. A pair of conductive layers formed on the envelope in an opposing relationship to and electrically connected to the discharge electrodes, and one of the conductive layers is opposed at least part thereof with the other conductive layer with a portion of the envelope interposed therebetween.

Abstract: The discharge tube of this invention does not employ special shapes of electrodes that are difficult to manufacture, but can still provide a uniform electric field. The electrodes are disposed in the inwardly drawn portions of the cylindrical body in such a way that the opposing front end surfaces of the electrodes are recessed from the inner surfaces of the inwardly drawn portions in a direction that they move away from each other. The discharge electrodes therefore do not project into the inner space of the cylindrical body but are enclosed by the inwardly drawn portions so that they are protected against influences of external electric fields from outside the discharge tube, thus assuring stable and reliable discharges.

Abstract: This specification discloses a spectacle frame of titanium or titanium alloy having at least one location a brazed portion of titanium or titanium alloy joined with titanium or titanium alloy, or of titanium or titanium alloy joined with other metal, characterized in that silver-zinc alloy comprising 70-95% by weight of silver and 5-30% by weight of zinc is used as the brazing filler metal material for brazing.
