Title: Production of magnetic recording medium
Inventor: SUGITA RYUJI
IPC: G11B5/85
Filed: 1994-06-17
Abstract: PURPOSE:To produce a thin film magnetic recording medium having high S/N at high productivity by providing a thin plate and an oxygen supply port on this side of the part where formation of a magnetic layer begins. CONSTITUTION:At the time of forming a magnetic layer by vacuum vapor deposition method on a traveling substrate 1, a thin plate 18 heated up to a temp. higher than the melting point of the material 7 to be vaporized is disposed on this side of the position 11 where formation of a magnetic layer begins. The thin plate 18 is disposed almost facing the substrate 1. At the same time, oxygen is supplied from an oxygen supply port 19 to the area 17 where a base layer is formed. The base layer is formed by deposition of vaporized atoms reflected by the thin plate 18. By this method, the vaporized atoms 9 are reflected by the thin plate 18 and deposited on the substrate. The deposited atoms are bonded with the oxygen supplied to form a nonmagnetic base layer. Just after the base layer is formed, a magnetic layer is formed in the same area as a conventional method. Thereby, since both of the base layer and the magnetic layer are formed by one traveling of the substrate, a thin film magnetic tape having high S/N can be produced with the same productivity as a conventional method.

Title: Drive method for solid-state image pickup element

IPC: H04N5/335
Filed: 1988-06-01
Abstract: PURPOSE:To obtain a clear video image without highlight afterimage by applying a pulse to part of a transfer electrode not in common to a readout gate electrode at readout. CONSTITUTION:A potential of a CCD register 7 under the 1st layer transfer electrode is kept higher than the set potential of a photodiode 5 to able to move the electric charge of the photodiode 5 to the CCD register entirely at readout. Thus, a potential higher than the charge storage is given also to the 1st layer transfer electrode 2 at readout. Since it is required to be kept while the photodiode 5 is set at least, the trailing edge of the timing of the pulse giving a high voltage is retarded from the trailing edge of the pulse.

Title: Metal vapor laser device
Inventor: HARA KAZUHIKO
IPC: H01S3/03
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a metal vapor laser which can hold a thermal shielding effect for a long time by providing a spacer and the like, and providing a predetermined gap between an innermost layer electrically connected to an outer metal tube and a sealing tube. CONSTITUTION:A spacer 15 is used to provide a predetermined gap between a sealing tube 18 and an innermost layer 14 to reduce an electric capacity between the tube 18 and the layer 14, thereby preventing a discharge generated in the gap. Thus, it prevents the tube 8 and the layer 14 from being deteriorated and particularly the optical reflectivity of the layer 14 from decreasing, thereby suppressing the increase in the thermal loss due to thermal radiation from the tube 8. Accordingly, an electric input necessary to raise an inner tube 6 to a predetermined temperature is not increased for a long period to increase the stability of a metal vapor laser. Since the gap is provided between the tube 8 and the layer 14 in this manner, the thermal shielding effect of the laser can be held for a long period.
