Title: Bender
Inventor: ISOZAKI TAKASHI
IPC: B21D5/02
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To allow workers having weak feet to bend without anxiety and to control a ram speed. SOLUTION: A punch P is cooperated with a die D by vertically moving a ram 5 to perform bending. In the case of bending, when a changeover switch 51 provided in an operating box 23 is switched for a foot switch, the start of the ram 5 is controlled by putting the foot switch 17 on ON or OFF. Also, when the changeover switch 51 is switched for a manual operating member, the start of the ram 5 is controlled by operating the manual operating member 55. Accordingly, the foot switch 17 or the manual operating member 55 is selected for workers by switching the changeover switch 51. By this way, bending is performed for workers having weak feet without anxiety by operating the manual operating member with hands.

IPC: C01G1/00
Filed: 1987-09-25
Abstract: PURPOSE:To contrive to improve sintering properties and to enable production of a superconducting ceramic having high density and high critical current density in the titled powder of A (rare earth element)-B (alkaline earth metal element)-Cu oxide system, by making the powder have a specific surface area in a specific range. CONSTITUTION:In superconducting ceramic powder shown by the general formula by AxByCu3O7-delta, having a layer perovskite structure of oxygen deficient type, the specific surface area is 3-15m<2>/g. With the proviso that in the formula, A is rare earth element B is alkaline earth metallic element, x=0.8-1.2, y=1.6-2.4 and 7-delta shows that number of O atoms is somewhat smaller than seven. Powder having <3m<2>/g specific surface area has bad sintering properties, a low critical current density, has difficulty in forming a thin film and provides a thin film having low strength. On the other hand, since powder having >15m<2>/g specific surface area is liable to cause secondary aggregation, the powder has poor moldability and has difficulty in forming a thin film.
