Title: Image formation device
Inventor: TAKAGI OSAMU
IPC: B41J2/385
Filed: 1994-12-14
Abstract: PURPOSE: To form beautiful images having no distortions by enabling a thin film aperture electrode body to be secured with accuracy in no wrinkle plane. CONSTITUTION: Since the aperture electrode body 10 is applied with tension from the supports 10a, 10b, at the time when the aperture electrode body 10 Is pressed against interposers 26, 27, forces F function on the Interposers 26, 27 to press them back. The interposers 26, 27 formed in a curved shape eventually allow the tangential forces F1 of pressing back forces F to function to prevent the occurrence of wrinkles of the aperture electrode body 10. Also, when the aperture electrode body 10 is mounted on the curved interposers 26, 27, it contacts in turn from the most projected central part to the end parts, thus wrinkles become hard to occur thereon.

Title: Dc-dc converter unit
Inventor: KAWAGUCHI KENJI
IPC: H02M3/00
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To shorten the high voltage circuit and to reduce a harness for high voltage thereby to reduce cost by providing a high voltage circuit including a main fuse and a branch circuit which is branched from the high voltage circuit and has a sub-fuse therebetween in a case and by connecting a DC-DC converter to the end of the branch circuit. SOLUTION: A current from a main battery 23 passes a main fuse 35 and an electric motor 17 to drive the motor (the first circuit). The current passes the main fuse 35, a sub-fuse 36, a converter 31 and lights 44 (the second circuit). The voltage is high from the main fuse 35 to the converter 31 and it is low in the downstream of the converter 31: that is to say, the high voltage part is exposed outside only between the main battery 23 and the converter unit 24 and the converter unit 24 and the motor 17. Therefore, the height voltage circuit is short and hence a harness with covering for high voltage and a waterproof connector are used in the reduced part.
