Filed: 1986-05-07
Abstract: PURPOSE:To increase a printing speed, by forming a leaf spring from a material having magnetic permeability and providing a protruded part forming a magnetic shunt to a closed magnetic circuit along with the leaf spring through a gap to a closed magnetic circuit forming member. CONSTITUTION:Two protruded parts 21 are provided to the outer surface of a bottom part 20b in a state protruded upwardly therefrom so as to form a U-shaped groove 24 having a leaf spring 19 arranged to the inside thereof along with the outer surface of the bottom part 20b and the depth of said groove 24 has such a dimension that the leaf spring 19 is not protruded from the groove in both cases at the time of printing operation and at a stand-by time. When a current is supplied to a coil 12, magnetic flux flows to a closed magnetic circuit 25 and magnetic shunts 27, 29 and, therefore, when no current is supplied to the coil 12 and an armature 5 is held to a stand-by state, the area of the side surface of the armature 5 forming a gap 23 in opposed relation to the inner surface of the through-hole 22 in a solenoid receiving body 20 can be smaller than when the magnetic shunts 27, 29 are not provided. Therefore, in this printing head, the height of the armature is reduced to make it possible to make mass small and a printing speed can be increased.

Title: Method and device for shaping lead wire of toroidal coil
Inventor: SUGAI KAZUHIRO
IPC: H01F41/10
Filed: 1990-04-19
Abstract: PURPOSE:To make it possible to shape leads in a normal direction automatically, by extending leads, which are both winding start and end portions of a toroidal coil, in the direction of the center axis of the coil, at both the sides of the coil, and by laying the leads across two rails and drawing downward the coil while holding the coil with a coil chuck. CONSTITUTION:Across rails 6 comprising two rods, lead wires 1, which are present respectively at winding start and end positions of a toroidal coil respectively, are laid in the state of the lead wires keeping extended in the axis direction of a toroidal core 2. The lead wires 1 are present at the positions on the inner wall of the center hole of the toroidal core 2. Therefore, the winding start and end positions of the toroidal coil respectively, are deviated from the center of the toroidal coil. For this reason, when the lead wires 1 are laid across the rails 6, owing to the gravity, both the winding start and end positions of the toroidal coil respectively, come to the position of, if liking, the number '12' on the dial of a clock. In this state, a part 7 for holding the coil, which has a coil chuck 8 mounted at both its sides with two sliding shafts 10 for positioning the coil chuck, lifts from under the coil, and holds the coil. Then, drawing downward the part 7, by the rails 6 serving as a guide, the leads 1 are precisely so shaped as to point from the aforementioned positions to the direction outside of the diameter of the toroidal core.

Title: Indirectly-heated cathode and its manufacture
Inventor: ETO GORO
IPC: H01J1/20
Filed: 1986-05-07
Abstract: PURPOSE:To obtaine an indirectly-heated cathode whose fine heater wire cannot be in contact with the metalic electro-conductive layer even when the electric insulating layer covering the heater wire has pinholes by producing the thin film of underlying metal on the insulating layer after filling up the pinholes in the said insulating layer with organic macromolecules and then burning and evaporating the said organic macromolecular layer. CONSTITUTION:Organic macromolecules are filled up in hollow portions in the thin film insulating layer having pinholes produced on the surface of a heater wire. Thereby the pinholes are eliminated and the hollow portions are also formed to equal thickness to the upper surface fo the insulating layer. On the surface of such a state a thin film of underlying metal is constructed. Thus the thin film layer of underlying metal is formed on the organic macromolecular layer over the pinholes cylindrically. Then by burning the wire in the atmosphere the organic macromolecular layer is oxidized and made to gases and evaporated through pinholes in the thin film layer of underlying metal. Thereby the hollow portions of the insulating layer are returned to the original state and the pinholes are reproduced, but the cylindrical underlying metal contacted to the upper surface of the insulating layer and the heater wire are faced to each other through the insulating layer having pinhole spaces so that the short circuit of the heater wire to the underlying metalic layer can be prevented.
