Title: Manufacture of wave absorber in quadragular pyramid shape
Inventor: IMAI TAKAYOSHI
IPC: C04B28/18
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To manufacture a wave absorber in a quadrangular pyramid shape which is used in a wave dark room or the like by connecting a small quadrangular pyramid made of calcium silicate of a low specific gravity to thereby make the whole wave absorber in a large quadrangular pyramid shape. SOLUTION: A truncated quadrangular pyramid, that is, a member in which four side faces are formed except for a vertex part of a quadrangular pyramid is first manufactured by cutting a calcium silicate plate in which shortly cut and opened carbon fibers are dispersed. A small quadrangular pyramid 3 made of calcium silicate of a low specific gravity in which shortly cut and opened carbon fibers are similarly contained is assembled into the vertex part of the truncated quadrangular pyramid, thereby forming a large quadrangular pyramid for wave absorber. A case-hardening agent is coated on the surface of calcium silicate to strengthen the surface. Since calcium silicate of a low specific gravity is not so strong and especially the surface is easily broken, strengthening the surface so as not to be easily broken is very advantageous when it is dealt or used.  It is preferable to use, as a case-hardening agent, an inorganic agent such as a sodium sulfate solution, a water glass, or a methyl silicate solution.

Abstract: PROBLEM TO BE SOLVED: To obtain a display apparatus by which a running route between points designated out of j present position, a passage place and a destination which are set in a route search is stored and by which the running route of a section which is deviated from a search route is stored. SOLUTION: In an apparatus, a route up to a destination from the present position of an own vehicle is searched, and its search route is displayed on a display means 109. A running-route storage means 106 stores the running route of the own vehicle. A storage-section designation means 107 designates the starting point and the end point of the running route, to be stored by the running-route storage means 106, out of the position of the own vehicle, the passage place and the destination. A judgment means 108 judges that the position of the own vehicle is situated in the designated starting point or the designated end point, and it instructs the start and the finish of the storage operation of the running route. In such a way, a running route between points designated out of the present position, the passage place and the destination is stored.  In addition, the judgment means 108 judges that the position of the own vehicle is deviated from the search route and that the position of the own vehicle is returned again to the search route. While the position of the own vehicle is deviated from the search route, the storage operation of the running route is instructed to the running-route storage means 106.

Title: Intention adaptable design device
Inventor: NISHIMURA SEIICHI
IPC: G06F17/50
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten the input time of an image (sensibility), which a user intends, and to facilitate the take-out of the intention of the user. SOLUTION: The user 12 visually recognizes the front elevation of a model displayed on a display part 19, and inputs sensibility words 'It fits well to the hand'. When a take-out part 16 takes out front elevation deformation data C111 from a model data base based on the sensibility word, front elevation deformation data C111 which is taken out is displayed on the display part 19. Namely, the front elevation of the model deformed by the inputted sensibility word is displayed. The user 12 inputs the sensibility word by viewing the front elevation of the model and therefore it becomes easier as compared to the case where the three-dimensional model is viewed and the sensibility word is inputted. Then, the processing time of data can be shortened since only a two-dimensional data processing is required.

IPC: G01R19/03
Filed: 1994-12-26
Abstract: PURPOSE: To precisely measure current by sensing a temperature of the full length of heater by a non-contact type sensor via a slit of an external conductor. CONSTITUTION: A coaxial line used as a transmission circuit for radio waves such as microwaves is employed. This coaxial line comprises a single internal conductor 1 with its periphery surrounded by an insulator 2, and the outside thereof is covered by an external conductor 3.
