Title: Electrophotographic device
Inventor: CHIN TEIU
IPC: G03G15/22
Filed: 1992-08-26
Abstract: PURPOSE:To utilize light utilized for an electrifying process, for an exposure and destaticization, as well and to simplify a constitution by using a common light source always located inside a photosensitive drum in each process of electrification, the exposure and the destaticization. CONSTITUTION:An electrifying process with the light is principally the same as in the conventional manner except that a fluorescent lamp 14 is arranged inside the photosensitive drum 12. In the exposure and developing processes, an induced charge enters an exposing region by the rotation of the photosensitive drum 12. Irradiation with the light from the fluorescent lamp 14 is selectively executed by a liquid crystal shutter 20 as necessary, to selectively discharge an electrified charge to the surface of a photosensitive body. Then, in the developing process, a toner image that toner is stuck to only a place where the charge exists can be obtained on the surface of the photosensitive body. The toner image is carried to a transfer region by the rotation of the photosensitive drum 12 and transferred/fixed on a paper 22. The photosensitive drum 12 is further rotated to a destatization region 24, a residual charge is removed with the light from the fluorescent lamp 14 and the toner is recovered in a developing unit.

Title: Semiconductor device
Inventor: NAKADA AKIRA
IPC: H01L21/339
Filed: 1983-12-01
Abstract: PURPOSE:To improve the performance of a semiconductor device acting as a bucket brigade by a method wherein conductivity of the channel in a controlling MOS transistor and the quantity of signals transmitted from the main current path into an output buffer-amplifier circuit are controlled for an output waveform containing less noise. CONSTITUTION:The drain electrode of a controlling transistor (TR) 11, located between a point 12 in a transfer stage and an output TR6, is connected to the gate electrode of its own and then to the point 12. The source electrode of TR 11 is connected to the gate electrode of TR6. Accordingly, TR11 is conductive only when the potential of the point 12 is higher, when signals overcoming the internal resistance of TR11 move forward to be charged into the gate electrode of TR6 and the region around it. A large-scale spike in voltage generated at the point 12 at the moment of transfer does not reach TR6. TR11 is thrown into non-conductive conditions upon completion of the charging, when the gate potential of TR6 is lower by the gate threshold voltage of TR11.

Title: Detection of insulation defect in power cable
Inventor: ENDO TAKESHI
IPC: G01R31/12
Filed: 1986-09-26
Abstract: PURPOSE:To enable detection of only a partial discharge clearly harmful with a delay in the progress of dielectric breakdown, by making the partial discharge deteriorate a cable insulating body to an extent to reduce energy of the partial discharge. CONSTITUTION:A partial discharge detection resistance 6 is connected to an intermediate section of a sample CV cable 5, a measuring device 7 is connected to a power source interruption controller 9 and a signal is sent from the partial discharge measuring device 7 to the power source interruption controller 9 when a discharge is found to reach a point where it is clearly identified as precursor partial stroke to interrupt the power source automatically. A difference between a normal partial discharge and a precursor partial stroke lies in the amount of electric charge being discharged. In other words, a partial discharge is judged depending on whether it grows larger than the normal partial discharge or it is generated from the non-discharge state and increases gradually. That is, any partial discharge is identified as precursor partial stroke to interrupt the power source when it increases with time. Then, the position thereof is located depending on where the partial discharge occurs.
