Abstract: PURPOSE:To obtain a steel having brightness of reflectivity after painting by printing fine patterns on the surface of a rolling roll by screen process printing and forming patterns on the surface by hardening treatment after the printing. CONSTITUTION:Fine patterns to be formed on the surface of a roll are drawn on a master drawing and the drawing is picked up on a negative 2 with a camera. After that, a photosensitive resin is applied to the whole surface of a screen net 3 to form a photosensitive resin film 4. The negative 2 is put on the film 4, printing is performed by an exposure device 5, development is performed by using a developer, and water washing is done. The finely patterned screen net 3 is completed by drying after washing. An acidproof ink 6 is put on the net 3 to print patterns on a roll surface 7. Then, the surface 7 is subjected to hardening treatment (vacuum deposition, ion plating, sputtering, etc.) to form embossed hardened layers 8 on parts to which the ink is not applied, the ink 6 is removed with an alkaline water solution to form uniform fine rugged patterns on the roll surface 7.

Title: Television receiver
Inventor: NODA TSUTOMU
IPC: H04N5/21
Filed: 1990-11-13
Abstract: PURPOSE:To obtain an audio signal immediately after channel selection and to improve the ghost elimination performance without extending a channel selection time by providing a detection means with faster response characteristic and a detection means with slower response characteristic to a carrier recovery means and using the both properly. CONSTITUTION:The response characteristic of video detection circuits 108a, 109 in each carrier recovery circuit is faster for the circuit 108a and slower for the circuit 109. Thus, the response characteristic of the AFT/AFC control circuit of the circuit 108a is also faster and when the AGC circuit of the circuit 108a is used by a changeover circuit 116, the channel selection is faster. Moreover, since an audio detection circuit 114 FM-detects the output of the circuit 108a, a video signal E has less waveform distortion due to ghost and the AGC circuit is slow, then no waveform distortion is caused in the detection output and the video signal is inputted to a ghost elimination circuit 110a. Thus, the audio signal is immediately obtained after channel selection without extending the channel selection time and the ghost elimination performance is optimized.

Title: Picture processing method and picture processor
Inventor: OUCHI SATOSHI
IPC: H04N1/40
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of picture quality by changing the resolution of an original at the time of separating an image area for the first time and the resolution of an original at the time of separating the image area after second time. SOLUTION: In pre-scanning, an edge separation processing and a dot separation processing are executed in parallel on a thinned picture. At the time of scanning, the color picture is reproduced by executing scanning for four times in one drum type and for once in four drum type, Whether a character is included in the original or not is judged in pre-scanning. When the character is included, thinning processing circuits 8 and 9 are turned off. An edge separation circuit 11, a dot separation circuit 12 and a color separation circuit 10 operate in parallel on picture data which is not thinned and respective judgment results are inputted to a judgment circuit 13. The judgment circuit 13 judges a black character, a color character and a pattern by means of the presence or absence of the edge, the dot and the color of a notice element.  Then, a processing is switched for respective picture elements in accordance with the result. Thus, the deterioration of picture quality can be prevented.

Title: Information reproducing device
Inventor: IKEDA HIDETOSHI
IPC: G11B7/085
Filed: 1986-12-20
Abstract: PURPOSE:To suppress the settling of an objective lens by applying a tracking servo action after a multi-jump with the single side of a differential signal kept eliminated for a fixed period. CONSTITUTION:When a reproducing action is carried out, an objective lens 6 has a multi-jump action to move to a track B from a track A of an optical disk 1. In such a case, the lens 6 is energized in the direction opposite to the jumping direction by the force of a plate spring which holds the lens 6. At the same time, a clamp circuit 29 is actuated for a prescribed period of time under the control of a CPU23. Then only the negative ones of track difference signals are clamped by the circuit 29. Thus, the force of only the jumping direction is produced by a drive coil 4 and the force of the plate spring is reduced. As a result, the lens 6 can be immediately held on a tack of the jumping destination after the multi-jump action. Then, the settling of the lens 6 is suppressed and a stable tracking action is ensured.

Title: Production of magnetic head
Inventor: MUKAIDE NORIAKI
IPC: G11B5/23
Filed: 1988-11-30
Abstract: PURPOSE:To prevent the peeling of ferrite-'SENDUST(R)' joint parts at the time of working and the generation of the deterioration in magnetic characteristics, by strain, etc., by sticking a magnetic material block formed with a thin ferromagnetic metallic film to a polishing surface plate lower by as much as the rough finishing allowance. CONSTITUTION:The one core block 1 is formed with track grooves 3 and a winding groove 4 and is then formed with the thin ferromagnetic metallic film 5 and a thin nonmagnetic material film (SiO2) 6 by sputtering on the joint surface to a prescribed thickness. Since only the core block of the magnetic head core block obtd. in such a manner has a projecting part 8, only the projecting part 8 is polished if the bottom plate is stuck to the polishing surface plate and the top end part is polished by a grinding wheel for rough finishing. Both the core blocks 1, 2 are polished if the top end is polished to a specular surface by using abrasive grains. The mirror finishing is thus completed. The peeling of the joint part and the deterioration in the magnetic characteristics by strain are obviated in this way.

Abstract: PURPOSE:To inexpensively produce many toner carriers in a short time with no need for an adhesive by scraping off a conductive resin film so that the conductive resin layer is exposed on the surface as the conductive part and the dielectric resin as the dielectric part. CONSTITUTION:A mixture of the powdery grains 5 of a conductive resin and the powdery grains 6 of a dielectric resin is injected from the nozzle of an electrostatic coating machine and applied to the periphery of a conductive support 1. The coat on the support 1 is heated to a temp. where only the conductive resin is melted, hence the grain 5 is melted, and the grain 6 remains unmelted. The conductive resin layer is then heated to the m.p. of the grain 6 of dielectric resin or its vicinity to adhere the grain 6 to the conductive-resin coating layer. The conductive-resin film layer is then cooled, solidified and removed by grinding and polishing, and the dielectric resin grain is exposed as the dielectric part.
