摘要： A throttle body as a part of an intake system capable of eliminating such problems that a weight and a cost must be reduced using a resin, the coefficient of linear expansion and thus the amount of thermal deformation varies due to a difference in orientation of filler relative to a bore even if the resin of the same material is used for a throttle valve because a clearance between the bore and the throttle valve of the throttle valve must be reduced to 80 to 100 νm or less, and the roundness after forming may be deteriorated due to a difference in shrinkage and thus an interference or excessive clearance may occur between the bore and the throttle valve, wherein the coefficient of linear expansion in radial direction is brought closely to that of the bore (4) by disposing grooves (17) concentrically so as to dispose the filler (2) in the resin in circumferential direction, and a bulk material formed by disposing the filler in circumferential direction is impregnated with the resin and then heat-cured, whereby the throttle valve (1) having the filler disposed in circumferential direction can be provided, and also the roundness of the bore (4) can be reduced by disposing a rib (28) near a throttle valve shaft so as to control the amount of form shrinkage.

摘要： PROBLEM TO BE SOLVED: To achieve great cost reduction by heating each of a plurality of plugs, controlling the shift to a desired depth, and uniformly drawing each of the plurality of molding regions of a sheet stock into each cavity. SOLUTION: Both of heated draw-in plugs 3a, 3b are lowered to a desired depth in the oblique direction toward a sheet central portion 7, which allows a sheet stock 1 to be supplied by being drawn in each cavity 8a, 8b a predetermined quantity against the nip with small frictional resistance between a lower expander 5 and an upper expander 4. The draw-in plugs 3a, 3b are controlled to be lowered to a desired depth at the oblique angles α, β adapted to the three dimensions of each cavity 8a, 8b, and the vicinity of the sheet central portion 7 of the sheet stock 1 is not stretched, which permits the sheet material 1 to be supplied by uniformly drawing in both the sides of the sheet stock 1. Such a draw-in molding reduces the reduction of the plate thickness, thereby manufacturing a high-quality product having a multi-tank shape.

摘要： PURPOSE:To stably and easily bend a semiconductor lead by inserting a lead into the lead supporting part of a clamp plate and exerting a compression force by advancing a lead clamp plate with pushing it down. CONSTITUTION:A lead supporting part 16 is arranged on the plane of a lead clamp plate 15. The external lead 2 of a semiconductor is inserted between lead supporting parts 16. The lead clamp plate 15 is pushed out in an arrow mark P direction to abut the tip T of the lead supporting part 16 and the shoulder S of the external lead 2. It is pushed out further with pushing the lead clamp plate 15 downwards and a compression force is impressed via the shoulder S on the bending part B of the external lead 2. Consequently the bending can be executed stably without causing a gap between the lead 2 and a mold 6.

摘要： PURPOSE:To prevent a gap from being produced between a lead and a resin after a bending process by a method wherein an inner lead is made thick before the lead is bent. CONSTITUTION:The following two parts are provided: a lower mold 12 where a groove is made at a part corresponding to a resin part and which supports a lead without coming in contact with the resin part; an upper mold 13, where another groove comes in contact with only the lead part. A semiconductor 7 is installed between the lower mold 12 and the upper mold 13 after a cutting process; then, a compression load is exerted on an external lead 2 by driving a press; the lead 2 is pressed down. By this process, an internal lead 3 is protruded by a height (d) due to the flow of a material and its thickness is increased. After that, the lead 2 is bent by using a bending roller. By this setup, a gap is not produced between the lead part 3 buried inside the semiconductor 7 and the resin part after a bending process.

摘要： PURPOSE:To enable to prevent the generation of a gap between conductors of a coil by a method wherein pressure is applied on a coil which is formed by lap-winding a conductors while their molded part is being made of long, and the coil is solidified using a bonding material. CONSTITUTION:Core pieces 14a and 14b are positioned by driving the core driving device 15 of a lower jig 18, and a coil 1 is formed by installing a lower plate 7A on a winding machine (not shown in the diagram). Then, said core pieces 14a and 14b are placed horizontally, hydraulic cylinders 5, 6 and pushing blocks 3, 4 are installed in such a manner that they come in contact with the coil. Then, the upper jig 19 is fitted to a winding core 14, and a fixed load is applied. Also, the above is heated up using the heater located in the pushing blocks 3 and 4. At this time, pressure is applied to the winding cores 14a and 14b by driving the winding core driving device while the interval of said winding core pieces 14a and 14b is being widened. After the bonding material has been turned into a fluidized state, the conductors of the coil 1 are adhered by solidification. As a result, no gaps or cracks are generated between the conductors of the coil.

摘要： PURPOSE:To bend a continuous rod having various curvatures efficiently without using a die by fixing an end of the rod and clamping another end freely movably and bending at desired curvature by giving only rotating force to the moving clamp. CONSTITUTION:A part of a rod 5 is clamped by a fixed clamp 8 and other part is clamped by a moving clamp 9. A motor 12 is driven, and rotating force is given to the moving clamp 9 through a universal joint 14 and a spline 15. At this time, the moving clamp 9 causes little resistance in moving in the directions X and Y, by the action of an X moving stand 18 and a Y moving stand 19 supported by a guide 16 for horizontal movement and a guide 17 for vertical movement, and only uniform bending moment is given to the rod 5 between the fixed clamp 8 and moving clamp 9. The rod 5 has uniform sectional form and stress- strain relation in longitudinal direction, and therefore, bending moment and radius of curvature have correspondence of 1 to 1. Accordingly, the part between two clamps 8, 9 is bent at uniform radius of curvature.

摘要： PROBLEM TO BE SOLVED: To provide a throttle body capable of suppressing size of a clearance to about the same size as conventional size by making amount of thermal deformation in a scope from very low temperature to temperature exceeding 100°C of a bore and a throttle valve substantially the same and realizing high performance at low cost.
SOLUTION: Coefficient of linear expansion in the radial direction is brought close to the bore 4 by setting orientation of filler in resin in the circumferential direction. For this reason, the orientation of the filler 2 is set in the circumferential direction by arranging a groove 17 concentrically. The throttle valve 1 with the filler orientated in the circumferential direction can be obtained by impregnating an aggregate constituted by arranging the filler in the circumferential direction into resin and then heating and hardening it. A rib 28 is arranged near the throttle valve shaft to control the molding contraction, which can make the circularity of the bore 4 small.

摘要： PROBLEM TO BE SOLVED: To reduce the weight of a formed article by reducing the thickness of a stock metal sheet, to fold the stock metal sheet to prevent occurrence of wrinkles and swelling or the like by keeping the sufficient flange folding width (creepage distance of inslation) so that the rust does not propagate to an outer surface of a corner part, and to keep the appearance of the corner part. SOLUTION: A stock metal sheet can be formed even when the width of a corner flange part 7 is not less than five times the thickness by also applying the contraction flanging to the corner flange part 7. The creepage distance of inslation is ensured thereby, and the rust is difficult to generate. A flat surface continuous to a long side flange part can be formed by providing a transition area 8 in a connection area of the corner flange part to the flange part.
