Title: Pad for light head phone
Inventor: MASANOBU YASUZO
IPC: H04R1/10
Filed: 1984-11-08
Abstract: PURPOSE:To make a pad difficult to be removed from a speaker and prevent the speaker inserting hole from expanding even after prolonged use by impregnating and fixing elastic resin or adhesive to the speaker inserting hole of the pad. CONSTITUTION:The pad 3 is made of foam such as 'MOLTPLANE' and impregnated and fixed with elastic resin or adhesive at the periphery of the speaker inserting hole 3a, about 1mm away from the inner circumference.

IPC: G03G21/10
Filed: 1986-10-02
Abstract: PURPOSE:To obtain a distinct color image by arranging a cleaning device whose fur brush contacts a photosensitive body at the time of cleaning and leaves it at other times nearby the photosensitive body, and bringing the conductive fur brush into contact and removing remaining toner. CONSTITUTION:A DC high-voltage power source 14 is connected to the fur brush 12 and a solenoid 15 which leaves the photosensitive body 1 except during cleaning is fitted to the cleaning device. When cleaning operation is performed, the fur brush 12 is pressed against the photosensitive body 1 and rotated in the direction opposite to the onward direction of the photosensitive body 1.5-3 times as fast as the peripheral speed of the photosensitive body. At this time, a DC voltage having the polarity opposite to the electrostatic charging polarity of toner is applied to the fur brush 12 and then toner on the photosensitive body 1 is attracted to the fur brush 12 electrostatically, so the cleaning ability is improved. The toner which is charged negatively can not be removed, so the residual toner on the photosensitive toner is recharged positively by an electrostatic charger 2 and passed through the cleaning device once more. Consequently a distinct color image is obtained.
