Title: Detecting method for remaining amount of developer
Inventor: WATANABE SHIYUUJI
IPC: G03G15/00
Filed: 1980-05-07
Abstract: PURPOSE:To detect a remaining amount of toner stably in an electrophotographic printer which uses single slips by forming a latent image at a break between forms by an array of LED, and by detecting it as a remaining-amount detection mark by a sensor by developing the image. CONSTITUTION:After the constant time T1 passes when form detecting mechanism 6 detects form 4a, LED array 2 is turned on for time T2 to form a latent image. Namely, the latent image is formed at the break between form 4a and the last form and when photosensitive drum 1 further rotates up to the position of sensor 8, sensor 8 detects it as a mark for detecting the remaining amount of toner to generate an output. The detection mark (latent image), if developing device 3 has not enough toner in it, is not formed with sufficient density. As a result, the output of sensor 8 is not sufficient and a slice level falls, thereby outputting a signal showing the lack of the remaining amount of toner. Thus, the remaining amount of toner is detected stably.

Title: High energy corpuscular ray generating device
Inventor: OKABE KENICHI
IPC: H01J37/317
Filed: 1993-03-19
Abstract: PURPOSE:To suppress the spattering of the constituting material from a protective wall by the collision of a corpuscular ray by setting the form and position of the protective wall in such a manner that a high energy corpusctular ray not selected is vertically incident on the surface of the protective wall. CONSTITUTION:When an ion is incident onto a target, the spattering quantity from the target is minimum when the incident angle of the ion is 0 deg., gradually increases as the incident angle is increased, reaches the maximum point at about 65 deg., and then sharply reduces. Thus, the incident angle of the ion is set to 0 deg. to minimize the spattering quantity from the target. Namely, the sectional form of a protective wall 4 provided in a chamber 1 is formed into a flat or curved surface so that the incident angle of the ion which is not selected and incident on the wall is 0 deg., whereby the spattering quantity from the wall 4 can be minimized. Thus, the life of a device is extended, and a sample to be treated can be prevented from being contaminated with the constituting material of the wall 4.
