Title: Formation of coating layer on alumina substrate
Inventor: UCHIDA KOJI
IPC: C23C28/00
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To form a uniform coating layer with high accuracy and good adhesion property at a low cost by forming a copper thin film on the surface of an alumina substrate, then immersing and arranging this substrate together with a counter electrode into a dispersion of the fine powder of the coating material, impressing a DC voltage between the copper thin film and the electrode to form an electrodeposited layer, then firing the layer. SOLUTION: The copper thin film is formed by an electroless plating method, etc., and its thickness is specified to 0.01 to 0.1μm. The coating material may be any insulating materials which are not particularly restricted; for example, alumina or crystallized glass is used. The average grain size of the fine powder is specified to 1.0 to 5.0μm and the fine powder is dispersed into a dispersion medium (e.g.: isopropyl alcohol contg. 2.0 to 5.0vol.% water) at ratio 0.075 to 0.25wt.%. The substrate is dried after the formation of the electrodeposited layer and is heated up to 900 to 1100 deg.C and is held for 3 to 5 hours in an oxidizing atmosphere; thereafter, the substrate is cooled down to 20 to 50 deg.C. As a result, the coating layer of alumina, etc., is formed via a chemical bonding layer of CuAl2 O4 spinel.

Title: Surface-state observing apparatus
Inventor: KOBAYASHI SHIGEKI
IPC: G01N21/956
Filed: 1990-10-30
Abstract: PURPOSE:To judge the surface state of the solid bounded by a curved surface by emitting the lights having the different colors from spot light sources in the directions corresponding to the different bearing angles and elevation angles from an object to be observed on the object under observation at the same time. CONSTITUTION:In a printed-board inspecting apparatus, the images of a positioning board 20S and a board under inspection 20T are picked up and compared.

Title: Flame-retardant optical fiber sheet
Inventor: TERADA HIROSHI
IPC: C03C25/24
Filed: 1989-11-14
Abstract: PURPOSE:To obtain the flame-retardant optical fiber sheet without deteriorating the fiber performance by using chlorinated polyethylene (PE) having >=38 oxygen index as a coating material. CONSTITUTION:At least one kind of the coating materials are constituted of the flame-retardant resin of the chlorinated PE which is the flame-retardant resin having >=38 oxygen index (OI), more preferably 40 to 43 OI. The entire part of the sheet is, therefore, flame-retardant as a whole even if the core is combustible. The chlorinated PE has the lower migratability of the resin component to the optical fiber 1 with lapse of time and does not exert an adverse influence on the light transmission performance of the optical fiber 1 particularly when the chlorinated PE having >=38 IO is used as the coating material 2. Since the chlorinated PE does not drip in spite of contact with a flame, the drip of the sheet itself is prevented. The excellent frame retardance is obtd. in this way and the deterioration in the fiber performance with lapse of time is prevented. In addition, the dripping of the optical fiber is prevented when the fiber is brought into contact with the flame.

Title: Elastic pavement material
Inventor: KADOWAKI YUKITAKA
IPC: E01C7/30
Filed: 1992-11-05
Abstract: PURPOSE:To improve performance and utilize industrial waste effectively by mixing asphalt, aggregate, and particles of thermoplastic polyester resin foam at a specific weight part. CONSTITUTION:2 to 10weight% of asphalt and 75 to 97.9weight% of aggregate such as crushed stones and sand are heated and mixed. Next, 0.1 to 15weight parts of particles and crushed objects of thermoplastic polyester resin foam such as polyethylene terephthalate are added to the above mixture to stir and mix for the use as pavement material. Foam may be obtained by crushing scraps such as trimming loss which is generated when food container is molded. Consequently, it is possible to hold the cushion property which is equivalent to soil and grass and improve durability and wear resistance. Further, thus obtained pavement material can be used to prevent noise and freezing of road because it excels in sound absorbing property and heat insulation property. Also, it is possible to utilize industrial waste effectively.

IPC: G01C21/00
Filed: 1993-11-25
Abstract: PURPOSE:To display by using data of present position before a key switch is opened without setting the present position every time the switch is closed. CONSTITUTION:A present position of a vehicle is operated by a microcomputer 4 based on detection signals from an azimuth detector 1, a distance sensor 2. A road map and the present position are displayed on a CRT display unit 6 by data for indicating the operated present position and map data read from a cassette tape 3a. In this case, the data for indicating the present position and the map data are power-backed up to a graphic memory of a CRT controller 5, and nonvolatile-stored. Accordingly, since the data are stored as they are even if a key switch is opened and closed, operations for setting the present position and searching the map to be displayed every time the switch is closed are eliminated, and its operability is improved.
