Title: Die and edging press device
Inventor: MASUDA BUNPEI
IPC: B21J1/04
Filed: 1989-12-07
Abstract: PURPOSE:To edge a slab into upward or downward curved state and to prevent torsion by forming vertical faces and oblique side parts on right and left dies which are brought into contact with side faces of slab and forming inclined faces which are opened upward or downward to the vertical faces on the oblique side faces. CONSTITUTION:In the case the slab 1 is edged with the dies 18, 18, since both end parts of the slab 1 in the width direction are restricted with the oblique side parts 14 and the slab is edged under the state that the direction of curve is always convex upward or downward, the torsion of the slab 1 is prevented with the oblique side parts 14 and also edging is made unnecessary by bringing the side faces of slab into contact with the vertical faces 19 in parallel parts 13 and keeping the side faces of slab at right angle.

IPC: H01G4/12
Filed: 1990-11-22
Abstract: PURPOSE:To make it possible to easily and attractively manufacture the title ceramic capacitor at low cost with less processes by a method wherein a terminal electrode, consisting of a directly-baked electrode layer, is formed on the end part of a laminated material without using a metal plate. CONSTITUTION:A baked electrode layer 18 of 60 to 80mum in thickness is formed on the end part of a stacked body 17. It is desirable that a plated layer 19a or 19b, which is formed at least by a kind selected from Ni, Sn or Sn/Pb, is provided as a base layer on the surface of the baked electrode layer 18. Also, it is more desirable that an Sn or Sn/Pb-plated layer 19b of 4 to 5 m is formed after an Ni-plated layer 19a of 1 to 2 m in thickness has been formed on the surface of the layer 18. As a result, the layer 18 can be protected completely by a heat-resistive Ni, the solder wetting property of the terminal electrode can be enhanced by the layer 19, and the oxidization of Ni can also be prevented. As a metal plate is not used, constitution is simplified, a complicated junction work to be performed on the metal plate is unnecessitated, and the title capacitor can be manufactured easily and attractively at low cost.

Abstract: PURPOSE:To prolong service life of a coining punch by providing a clearance for escape at the bottom of a joint yoke material, giving pressing force to the projected part of a coining punch in X direction only, giving pressing force on a shoulder, to make coining process. CONSTITUTION:In coining process, pressing force on the projected part 8 of a coining punch is not given in X direction but given only on claws 2a and 2a in Y direction, since a clearance is given between a bottom part 3 and the projected part 8 due to clearance for escape and a joint yoke material 1 is in horse-shoe type and opened in X direction. A force excerted on the projected part 8 works as compressive force due to the pressing force and shearing force and bending force are offset. On the other hand, the yoke inner diameter d2 of the joint yoke is machined precisely. By sinergetic effect of two conditions that shearing force and bending force are not given onto the material flow and the coining punch, roughly even pressing force is exerted on the contacting surface between a shoulder 9 and a sliding surface 2b, and the thickness t of the sliding surface 2b and an inclination angle theta are formed roughly even over entire area of the sliding surface 2b.
