Title: Manufacture of pipe made of ceramics
Inventor: ASANO OSAMU
IPC: B28B3/20
Filed: 1988-09-30
Abstract: PURPOSE:To obtain a pipe having a fine hole superior in perfect roundness, perfect straightness and a degree of a coaxial state, by a method wherein an extrusion-molded body where section is in a circular state and a core wire is buried is compressed by a hydrostatic pressure press, the core wire forced out through at least an end of the molded body is pulled out through decompression after pressing and the molded body from which the core wire is pulled out is baked. CONSTITUTION:When a ground material is extruded by passing through between an inner circumferential wall of a mouthpiece 10 and an external circumferential wall of an inner core 13 of the mouthpiece 10, the ground material becomes tubular, in the central part of which a fine hole whose section is in a circular state is formed and a core wire 15 is buried in the fine hole. The core wire 15 to be buried is drawn out into the fine hole to be formed in about the center of the ground material with extruding force of the ground material and becomes a state where the core wire 15 is buried linearly into the center of an extrusion- molded body led out through a nozzle 10b. Then after the extrusion-moded body is dried uniformly from the surface of a surface layer down to the inside, latex is applied to the surface of the surface layer of the extrusion-molded body under a state where the core wire is buried and hydrostatic pressure pressing is performed. When pressure to be applied to the press-molded body is eliminated after the hydrostatic pressure pressing, the core wires 15 are forced out through both ends of the extrusion-molded body. The forced out core wire 15 is pulled out through an end of the extrusion-molded body and the obtained extrusion- molded body is baked.

Title: Manual insertion type ic card reader
Inventor: MORIGAKI MASAMICHI
IPC: G06K7/00
Filed: 1984-11-26
Abstract: PURPOSE:To always secure a contact with a proper level of pressure between a card reading contact and an IC card by securing such a mechanism where a header moves back independently to absorb the excessive pressing force when the contact pressure has an excessively high level. CONSTITUTION:When a manual lever 6 is pressed down, a coupling pin 21 interlocks a hooking recess part 20a of a guide groove 20. Thus the lever 6 is fixed temporarily and at the same time an IC card 4 is enclosed by the lever 6. Then a solenoid 22 is energized to pull a cam lever 25. While lock levers 28 and 28 are moved to the outside and put into a lock hole 33 of the level 6. Thus the lever 6 is locked at a lower position. The contact pressure of a card reading contact 13 is elastic to the card 4 since a header 11 containing the contact 13 is supported by the lever 6 via a plate spring 12. Then the header 11 moves back independently of the lever 6 and against the spring 12 as the contact pressure is set at a higher level. Thus the contact is always kept at a proper level of pressure between the contact 13 and the card 4.
