Title: Electrophotographic device
Inventor: NOGUCHI TERUHIKO
IPC: G03G15/06
Filed: 1989-11-10
Abstract: PURPOSE:To suppress deterioration caused by the fatigue of a whole photosensitive body by operating a main electrifier and a transfer electrifier only for a printing part which is the minimum necessary part of the photosensitive body. CONSTITUTION:A control part 7 detects the printing part on the surface of the photosensitive body corresponding to the image part of a printing pattern from the printing pattern stored in a storage part 8. Then, when it detects the facing state of the printing part and the main electrostatic charger 2 based on the position of the printing part and the output of a moving position detection means 9, it turns on the charger 2, and turns on the transfer electrifier 4 when it detects the facing state of the printing part and the charger 4. Besides, the control part 7 turns off the electrifier 2 when it detects the facing state of a nonprinting part and the electrifier 2 and turns off the electrifier 4 when it detects the facing state of the nonprinting part and the electrifier 4. Therefore, the electrifier 2 and the charger 4 are operated only for the printing part of the photosensitive body by the control action of the control part 7 with respect to the electrifier 2 and the electrifier 4. Thus, the deterioration caused by the fatigue of the whole photosensitive body is suppressed.

Title: Semiconductor acceleration sensor
Inventor: HOSOYA KATSUMI
IPC: H01L29/84
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor acceleration sensor in which an insulating film for inhibiting contact of a movable electrode with a fixed electrode is kept from dielectric breakdown due to discharge caused in anode joining. SOLUTION: A silicon substrate 2 having an overlap part 6 displaced by acceleration is anode joined to the upper surface of a glass substrate 1 having a fixed electrode 8 to be integrated. The overlap part and the fixed electrode are opposite to each other, and the opposite surface of the overlap part is taken as a movable electrode 7. On the surface of the glass substrate, an insulating layer 11 is provided through an electrode material 10 in a fixed electrode unformed area 8a in a position opposite to the movable electrode 7. Thus, when the overlap part is largely displaced, the movable electrode 7 and the insulating layer 11 first come into contact with each other so that both electrodes are kept from electric contact. Further, since the fixed electrode 8 and the insulating layer 11 are out of contact, in anode joining, discharge is caused between both electrodes, and at that time, high voltage is applied to the insulating layer 11 not to cause dielectric breakdown.

Filed: 1989-11-14
Abstract: PURPOSE:To prevent contamination of a scintillator due to evaporation substance of a sample by providing an electron incident opening on the side of the sample at a position shifted from the axis of the scintillator. CONSTITUTION:A secondary electron (e) emitted by irradiating a sample S with primary exciting beam E is withdrawn from the sample S through an earth electrode 1, an electron attracting electrode 2 and the second earth electrode 3 to be converged in the vicinity of the opening of the electrode 3 and repelled by the negative potential of a repeller 4 to be prevented from straight advance and attracted by the high potential of the scintillator 5 exposed through the opening 41 provided at the lower part of the electrode 4 to be bent in its track and accelerated to be incident to the scintillator 5. A photomultiplier tube 6 converts the light from the scintillator 6 to an electric signal thus detecting the electron (e). At this time, the contaminant (a) evaporated from the sample S advances straightly through the openings of the electrodes 1 - 3 but only impinges against the bottom of the electrode 4 and incapable of being incident to the scintillator 5. Therefore, contamination of the scintillator 5 is prevented and detection sensitivity is stably held over a long period of time and the life of a detector is extended.
