Filed: 1994-09-20
Abstract: PURPOSE: To contine pattern borders and making patterns fine or controlling phases concerning the method for generating a triangular pattern as a pattern unit, and to generate a lot of kinds of patterns. CONSTITUTION: First of all, a three-dimensional pattern is generated in a three- dimensional space by using a solid texture. Next, a cone shape is segmented from three-dimensional pattern space, and the three-dimensional pattern is provided on the side surface of the cone. Then, this side surface of the cone is opened at one position from the apex to the base and extended into a triangle. The patterns of this triangle are linked while making the opened sides adjacent and extended into a polygonal pattern. In this case, the side surface of the cone can be bilaterally symmetrically extended into the triangle as well. The patterns are continued at the sides opening the side surface of the cone and by making the triangular patterns adjacent, the polygonal pattern of continued borders can be generated.  When the side surface of the cone is bilaterally symmetrically extended, the pattern of the base is made bilaterally symmetric and even when this polygonal pattern is made adjacent, the pattern of continued borders can be generated as well. Further, the pattern can be controlled corresponding to the definition of the cone.

Title: Manufacture of incombustible power cable
Inventor: SAKAMOTO HIROSHI
IPC: H01B13/00
Filed: 1988-09-09
Abstract: PURPOSE:To obtain an incombustible cable having little chlorine emission during use by previously heating an incombustible power cable containing chlorine up to a room temperature or to a temperature above a use temperature for holding it. CONSTITUTION:An incombustible power cable containing chlorine is held in the range of 50 deg.C to about 80 deg.C for more than 240 hours. Thereby, a chlorine component easy to be emitted is previously emitted. Here, a heating temperature before use is preferably to be high because chlorine can be emitted in a short time, however, a power cable generates insulation deterioration, when it is heated above 80 deg.C so that the maximum temperature shall be 80 deg.C. Further, the heating time of more than 240 hours is necessary, because, according to results of an experiment, chlorine emission amount starts to be saturated in 240 hours even when heated at 75 deg.C. Heating time is desirable to be long so that an upper limit is not necessary to be fixed.

IPC: G01P5/12
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a thermal type flow velocity sensor which is excellent in durability and measuring accuracy. SOLUTION: A wind velocity detecting element 20 constituting a wind velocity sensor 10 consists of a bar member 21 made of an insulation material wherein a metallic wire 20a whose electric resistance varies in accordance with the loss of heat due to wind is wound therearound and a heat generation wire 20b is wound between the wires 20a and 20a.
