Title: Picture file device
Inventor: AOKI NORIO
IPC: G06F17/30
Filed: 1989-11-24
Abstract: PURPOSE:To increase the processing sped in a retrieving process where the retrieving information and the index pictures are used by arranging the retrieving information and the picture data necessary for reproduction of the index pictures at the areas physically close to each other. CONSTITUTION:A memory space 2 of an optical disk serving as a storage medium 1 is divided into a retrieving information area 3, a retrieving picture data area 4 which stores the index picture data necessary for decoding the pictures of the lower rank hierarchies used for index pictures, and a picture data area 5 which stores the picture data except the index picture data. The tracks physically close to each other are allocated to both areas 3 and 4. Therefore a head serving as a movable part of a storage moves only in the areas of both areas 3 and 4 in a retrieving process. Thus the large head seek can be evaded. Then the overall processing speed is increased.

Title: Production of color display device
Inventor: KAMAMORI HITOSHI
IPC: G02F1/1333
Filed: 1989-11-24
Abstract: PURPOSE:To prevent the breaking of an electrically conductive transparent film by forming an over coat layer on color filters in a certain region and polishing the resulting color filter substrate from the over coat side. CONSTITUTION:An over coat layer 2 on color filters 1 is formed in the entire region of a substrate 5 except at least the connection terminal part. The resulting color filter substrate is then grounded from the cover coat side 2. Since abrasive cloth is brought into contact with the entire surface of the substrate at the time of grinding, the angular part of the over coat layer 2 is easily grounded and made roundish. When an electrically conductive transparent film 3 is formed on the grounded color filter substrate, the breaking of the film 3 due to step coverage of step part is prevented.

Inventor: HIEDA MASAHIRO
IPC: C08J5/14
Filed: 1992-11-17
Abstract: PURPOSE:To provide a friction material which has little possibility of peeling, has high abrasion resistance and high coefficient of friction, and can be easily produced at a low cost. CONSTITUTION:This friction material is made by baking an organic resin coating layer on the surface of a core material comprising iron, aluminum, titanium or an alloy containing at least one of them, wherein a number of fine projecting stripes are provided on the surface of the core material. Accordingly, this friction material is excellent in adhesion and close contact between the core material and the coating layer and free from the problem of peeling. The presence of the fine projecting stripes of the core material can dispense with the incorporation of inorganic fibers into the coating layer. Since the fiber-shaped etching pattern of the fine projecting stripes is oriented at random, the friction material is resistant to forces from all the directions so that neither partial cracking nor partial peeling will occur in the material. It is excellent in abrasion resistance, durability, mechanical strength, heat resistance, etc., has a stable and good coefficient of friction, and can be very easily produced.
