Title: Internal interpolation method for polygon
Inventor: ISHIKAWA MASAJI
IPC: G06T15/80
Filed: 1989-03-30
Abstract: PURPOSE:To display a three-dimensional graphic, etc., at high speed by calculating the horizontal direction increment value and vertical direction increment value of two orthogonal axes in initial processing and parallelly calculating a Z coordinate value Z and a luminance value I independently for each internal point of a polygon. CONSTITUTION:The horizontal direction increment value and vertical direction increment value of the Z value and I value concerning the two orthogonal axes in the polygon are calculated and the polygon is divided into the prescribed number of parts. Then, the internal interpolation of the Z value and I value on a polygonal surface is parallelly executed by using the horizontal direction increment value and vertical direction increment value. Namely, since the horizontal direction increment value and vertical direction increment value of the two orthogonal axes are calculated in advance, the calculation can be independently executed regardless of whether the Z value and I value of the other points are calculated or not for the point in the internal part of the polygonal surface. Thus, the internal interpolation of the polygonal surface can be parallelly executed and a processing speed can be improved.

Inventor: SHIODA TAKAO
IPC: G02B6/44
Filed: 1980-06-16
Abstract: PURPOSE:To obtain an optical fiber having a protecting film which protects the fiber against blackening by visible rays and ultraviolet rays by passing the fiber consisting of silver halide in an eutectic mixture contg. silver sulfide and depositing silver sulfide on the fiber surface. CONSTITUTION:A fiber 1 consisting of silver halide produced by a puller 3 is guided to guide rollers 4, 5, and is introduced into the inlet part 6a of a melt tank 6. The melt 7 of an Ag2S-AgCl type eutectic mixture contg. sulfide is contained in the tank 6, and the temp. in the tank 6 is so set as to be successively lower from an inlet part 6a toward an outlet part 6b. In the inlet part 6a, the melt 7 of silver sulfide and silver chloride sticks on the surface of the fiber 1, and in the intermediate part 6c and in the outlet part 6b, only the silver sulfide deposits on the surface of the fiber 1. The melt of the silver chloride having stuck on the surface of the fiber 1 returns into the melt 6. In this way, the protecting film consisting of silver sulfide is formed on the surface of the fiber 1.

Title: Egr gas cooling device for internal combustion engine
Inventor: OGAWA HIROSHI
IPC: F02M25/07
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide an EGR(exhaust gas reflux) gas cooling device capable of enhancing a cooling performance, a reliability and an exhausting performance of an internal combustion engine. SOLUTION: Since an introducing portion 17 of which L1 is long is provided and an entrance portion 15 is connected to the introducing portion 17 from an approximately orthogonal direction, and EGR gas introduced from an exhaust passage 11 is collided and diffused at an inner wall of the introducing portion 17 and approach-run by a predetermined distance (L1), and then, the gas can be introduced to a plurality of heat-transfer tubes 19. Therefore, the EGR gas can be introduced to a plurality of heat-transfer tubes 19 at a uniform flow rate distribution and it can be avoided that the EGR gas is introduced to a specific heat-transfer tube 19 at an extremely high speed.  Thus, since conventionally, an increase of a local heat transfer generated at a high flow rate portion can be inhibited, boiling of a cooling water can be avoided and a cooling efficiency can be maintained at a high degree. Further, since lowering of an intake temperature and a permitted EGR ratio limit can be improved, and exhausting performance can be also enhanced. Moreover, since boiling of the cooling water can be suppressed, thereby to restrain the damage of the heat transfer tube 19.

Abstract: PURPOSE:To improve the filling-up efficiency of concrete, by a method wherein the inside part of a steel pipe column to be weld joined with the flanges of beams is weld joined with longitudinal ribs and diaphragms, and at the positions corresponding thereto the flanges of the beams are weld joined with the steel pipe column, following which the steel pipe column is filled with the concrete. CONSTITUTION:Reinforcing fixtures, each of which is formed by joining longitudinal ribs 2 with a diaphragm 3 having a round opening by welding, are weld joined with the inside part of a steel pipe column 1 and at the positions corresponding thereto the flanges of beams 4 for the steel pipe column 1 are to be welded. After that, at these positions, the flanges of the beams 4 are weld joined with the steel pipe column 1 and a joint is formed, following which the steel pipe column 1 is filled with concrete 5. Since the strength of the diaphragm 3 having a large opening is not enough, the steel pipe column 1 is reinforced so that internal and eternal stress thereagainst can be distributed by the longitudinal ribs 2. In this way, the strength of the steel pipe column 1 is adequately ensured and the filling-up efficiency of the concrete can be improved by enlarging the opening for the filling-up of the concrete.

IPC: G01F1/00
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To measure a very small flow rate where no Karman vortex is stably generated in fluid to be measured. SOLUTION: A vortex flow meter 11 includes heat generators 18 composed of electric heaters or the like attached to the center parts of slopes 17b and 17c in the downstream side of a vortex generator 17.

The heat pulse generated in the measured fluid by the heat generator 18 is detected by using an ultrasonic transmitter 19 for detecting a Karman vortex and an ultrasonic receiver 20. Then, a flow rate is calculated based on a phase difference between an ultrasonic wave transmitted from the ultrasonic transmitter 19 as in the case of detecting the Karman vortex and a demodulation signal for detecting the heat pulse.
