Title: Steel sheet for can excellent in corrosion resistance and weldability
Inventor: MORITA JUNICHI
IPC: C25D11/38
Filed: 1989-01-10
Abstract: PURPOSE:To obtain the steel sheet for a can excellent in corrosion resistance and welability by sealing the pinhole part of a metallic chromium layer having specified plating amount which has been formed on the surface of the steel sheet and forming resin layer on the layer. CONSTITUTION:A metallic chromium layer of 20-150mg/m<2> is formed on the surface of a steel sheet. This metallic chromium layer is obtained by plating metallic chromium and removing chromium oxide formed on the top layer thereof. Then the pinhole part of the metallic chromium layer is sealed. This sealing treatment is preferably performed by electrodepositing one kind of Ni, Sn, Zn and Cu to the pinhole part by electroplating. In this case, plated amount of Ni, etc., is favorably regulated to about 5mg/m<2> or below. Thereafter a resin layer is formed on the metallic chromium layer. This resin layer is obtained by applying e.g. PE, polyester, PP and 'Saran(R)', etc., at about 20-150mg/m<2>. In this case, conductive substance such as graphite can be dispersed in the resin layer, if necessary. Thereby the steel sheet for a can excellent in corrosion resistance and weldability is obtained.

Title: Capacitive light emitting element display device and driving method therefor
Inventor: ISHIZUKA SHINICHI
IPC: G09G3/32
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To provide the driving method for a capacitive light emitting element display, by which the adjustable range of rightness can be extended or the brightness can be adjusted in good linearity by regulating the potential of reverse bias voltage. SOLUTION: A control circuit compares the brightness signal level of a stored image data of one field with that of an image data of this time, and if both have the same brightness level value (S3), the circuit maintains the previous brightness value and supplies the same reverse bias potential control signal as the previous one to a reverse bias adjusting circuit (S4). When it is judged that they have not the same brightness level value, the circuit updates the brightness level value and supplies a reverse bias potential control signal based on the updated brightness level value to the reverse bias adjusting circuit (S5). A cathode line scanning circuit adds a reverse bias voltage according to the reverse bias potential control signal to the cathode line to be not scanned.  Moreover, an anode line driving circuit sequentially supplies a driving current corresponding to the image data for each horizontal scanning period (S6).

Title: Manufacture of one side molten metal plated product
Inventor: NISHIKAWA SEIJI
IPC: C23C2/00
Filed: 1979-01-17
Abstract: PURPOSE:To perform continuous plating on one-side of a steel strip by a method wherein electromagnetic coils are installed in a molten metal plating tank to allow energized coils to generate magnetic force to raise molten metal, which is made to contact one-side of steel strip which is running. CONSTITUTION:Molten metal tank 2 is installed with electromagnetic coils 4 contained in heat resistant housing 5 such as ceramic, from the top near the surface of molten metal tank 2. When the coils 4 are energized with multiple phase AC current, magnetic field in M direction induces movable magnetic field from the lower electrode coil to upper electrode coil. This causes magnetic field in F direction to move. This action causes the molten metal 2 to move in f direction so that raised portion is formed on the surface of the bath. This elevated metal is made to contact the lower surface of steel strip 1 which is running, so that molten metal plating is performed. The contact area of the steel strip 1 and the molten metal 2 is curved by the positioning roller 3 depression, and oxidation-preventive gas is jetted from the nozzles 6. Both means prevent excessive bath rise, so that the top surface of the steel strip 1 is protected from being plated with penetrated molten metal.

Abstract: PURPOSE:To obtain a good output of a printer by providing a photo-waveguide from the lower end of an EL light emitting element up to the vicinity of the end surface of a substrate, and forming said photo-waveguide into the shape to which the projected light is converged. CONSTITUTION:Two adjacent photo-waveguides, for example, Fi-j and F(i+1)-j are arranged so that the light projecting ends thereof are almost in contact with each other. In other words, a light 53 projected by a light emitting part 50 of an EL element is reflected sometimes by the side face of a photo-waveguide 51. The reflecting angles 54, 55 at this time become smaller towards the projecting end of the photo-waveguide 51 and the projected lights 7 become parallel. As a result, the profile of the projected light of an EL array head at the surface of a photosensitive body becomes good. Since the adjacent photo-waveguides are in contact with each other at the projecting ends thereof, the adjacent dots are brought in touch with each other at the developing time, without generating an unnecessary space between dots, thus realizing high- quality printing.
