Title: Radiation image photographing device
Inventor: WATABE TETSUO
IPC: G01T1/00
Filed: 2001-07-24
Abstract: PROBLEM TO BE SOLVED: To fulfill both of anti-shock capability and image quality of a radiation image photographing device.

Title: Terminal plug for testing relay
Inventor: IDE KOICHI
IPC: H01R13/642
Filed: 2001-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary operations for a relay which may be generated at plug insertion time. SOLUTION: A testing terminal 1 has first an second contacts 5 and 6. A plug 11 is provided with first and second conductive parts 13 and 14 different in the length. When inserting the plug 11 into the terminal 1, the longer conductive part 14 contacts with the first contact 6, and then the first conductive part 13 contacts with a contact piece 5.
