Title: Metallic decorative ware and manufacturing method therefor
Inventor: IMAMICHI MASAFUMI
IPC: B44C1/22
Filed: 2001-05-22
Abstract: PROBLEM TO BE SOLVED: To solve such problems that in a conventional decorating method by which an oxide layer is previously formed on the surface of a metal ware by a chemical change treatment and an iridescent luster is reflected only in the oxide layer by a thermal change, the previously performed chemical change treatment is troublesome and a laser beam irradiation device is extremely costly with such other disadvantages that a recessed part formed by the irradiation with a laser beam is extremely small and lacking in depth, and shows a fuzzy outline, which is less visually impressive.

IPC: H01R13/53
Filed: 2001-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a connector which can reduce an arc generation time and can control deformation of a contact and a housing by an arc heat. SOLUTION: The connector 11 is provided with a female connector housing 13 having a female terminal 12 and a male connector housing 15 having a male terminal 14.
