Title: Upper case electrode to operate parallel electrode etching
Inventor: ROBAATO UU
IPC: H01J37/32
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an etching system which is capable of substantially protecting an upper electrode from corrosion even if dry cleaning for removing deposits from the upper electrode is reduced to an irreducible minimum or dispensed with. SOLUTION: An upper electrode (anode) 14 coated with polymer deposits in an normal operation is self-cleaned through 21 control method related to a plasma etching reactor. In one practical method, RF plasma is used for continuously feeding an electric power through the intermediary of a lower electrode, and an RF power much smaller than a main RF power which generates and keeps plasma in an etching reactor 10 is applied to the upper electrode 14. The small RF power is so set at a certain power level so as to continuously remove the deposits from the upper electrode 14 but not to remove the electrode material. In another practical method, an electrical power is intermittently applied to the upper electrode 14 in a cleaning period, and no electrical power is applied to a lower electrode 12 in a cleaning period.  These two cleaning methods may be combined, or a continuous cleaning is complemented with an intermittent cleaning in an interruption period in a etching process.

Title: Semiconductor photodetector
Inventor: SHIMAUCHI KAZUFUMI
IPC: H01L31/10
Filed: 1994-12-28
Abstract: PURPOSE: To obtain a semiconductor photodetector in which light incident on parts other than a light-receiving part is blocked surely by a method wherein a metal layer is formed on an oxide film excluding a base light-receiving part region as the light-receiving part for a phototransistor element. CONSTITUTION: Parts other than base light-receiving regions in P-type diffusion regions 12, 13 are covered with a metal layer 21. As a result, light, from a light-emitting diode 4, which is passed through a slit in a rotary encoder 3 can be shone at only the base light-receiving regions, and a noise current can be prevented surely. Since the metal layer 21 is formed on an oxide film 20, a kind of MOS structure is formed. When the light is shone at the regions, carriers are generated in the metal layer 21, a potential difference is generated between the metal layer 21 and an epitaxial layer 11, a leakage current is generated when an inversion layer is formed and the characteristic of a phototransistor as a single body is lowered remarkably. Consequently, the metal layer 21 and a semiconductor substrate 10 are connected electrically so as to be an identical potential.  Thereby, even when the carriers are generated in the metal layer 21 due to irradiation with the light, an inversion layer is not formed in the semiconductor substrate 10.

Abstract: PURPOSE:To miniaturize a device and to output a color image at a high speed by executing color switching in one developing device which stands by when developing is executed by the other developing device. CONSTITUTION:At the developing time by the first developing device 4, it is only cleaning liquid 25 that is supplied to the developing gap of the second developing device 5. Besides, potential which is equal to the developing electrode of the device 4 is impressed on the developing electrode of the device 5. Therefore, when a toner image formed on a photosensitive drum 1 by the device 4 is passed through the device 5, the image deterioration of the toner image caused by the remigration of attached toner, the attachment of the other toner or the like is prevented. Besides, even at the developing time by the device 5, it is only the cleaning liquid 25 that is supplied to the developing gap of the device 4. By executing the color switching of the other developing device 4 (5) which stands by in such a way, many developing devices need not be provided and the color image is formed at a high speed.

Title: Recorder of still picture
Inventor: OMATA YOSHIKATSU
IPC: H04N19/103
Filed: 1989-12-19
Abstract: PURPOSE:To prevent production of an error of a recorded picture data by reducing the compression rate when a decoded picture data and a still picture data are dissident, compressing the data again while the compression rate is reduced and recording the compressed picture data onto a recording medium when the decoded picture data is coincident with the still picture data. CONSTITUTION:Picture data compression circuits 17-19 compress a still picture data and the compressed picture data is stored by a compression data storage circuit 20 and picture data decoding circuits 21-23 decode a compression picture data. Then a still picture data and a decoded picture data are compared by a comparator circuit 25 and when the still picture data and the decoded picture data are dissident, the still picture data is again compressed with a small compression rate. When the still picture data and the decoded picture data are coincident, the compression picture data at that time is recorded onto a recording medium. Thus, the still picture data is compressed without causing an error and lots of still picture data are recorded.
