Abstract: A two-color molding method in which, when a secondary molded body is formed by covering the surface of a primary molded body made of a reinforcing-fiber-containing synthetic resin material with a reinforcing-fiber-free synthetic resin material, these synthetic resin materials may differ and the production cost does not increase. When a primary molded body is formed by injecting a molten reinforcing-fiber-containing synthetic resin material into a primary molding cavity, the molten reinforcing-fiber-containing synthetic resin material flows from one end toward the other end of the primary molding cavity and a short shot is performed. This exposes reinforcing fiber in a tooth of the primary molded body positioned at the other end of the primary molding cavity. In the secondary molding cavity, the tooth in which the reinforcing fiber is exposed is covered with a reinforcing-fiber-free synthetic resin material to form a synthetic resin gear as a two-color molded body.

Abstract: Plural ejector pins are made to project before a molten resin containing reinforcing fibers is injected into an inside of a cavity through pin point gates in a web forming portion in the inside of the cavity and at positions outside the pin point gates in a radial direction. The ejector pins are retracted from the inside of the cavity after a flow of the molten resin containing reinforcing fibers injected into the inside of the cavity through the pin point gates impinges on the ejector pins and is divided and before a tooth portion forming portion in the inside of the cavity is filled with the molten resin containing reinforcing fibers. Accordingly, weld lines which extend along the radial direction are formed at positions outside the ejector pins in the radial direction, and the molten resin is filled in portions formed after the ejector pins are retracted.

Abstract: A nozzle plate for a fuel injection device opposes a fuel injection port of a fuel injection device. A nozzle hole through which fuel injected from the fuel injection port passes is formed at the nozzle plate. At this nozzle plate for the fuel injection device, the nozzle hole has a fuel-flow-in-side opening end with a circular shape. The nozzle hole is coupled to the fuel injection port via fuel guide channels. The fuel guide channels have an opening into the nozzle hole, and a pair of opposing channel sidewalls. The opening has a channel width smaller than a hole diameter of the nozzle hole. One of the opposing channel sidewalls is formed to extend in a tangential direction of the nozzle hole. The fuel is directly flowed into the nozzle hole to generate a flow of the fuel in a spiral pattern in the nozzle hole.

Abstract: In the light flux controlling member (5), the angle between an optical path of light output from the light emission center (14) of a light emitting element (4) and optical axis L1 is ?2. Light is incident on the light flux controlling member (5) through an input surface and travels inside the light flux controlling member at an angle ?2 with respect to optical axis L1. Then, light is output from a light control output surface (10) at an angle ?3 with respect to optical axis L1. The input surface (15) and the light control output surface (10) are formed such that, in a range 0<?1??1max, the relationship between ?1 and ?2 is reversed from ?1<?2 to ?1>?2 when ?1 increases, and the relationship between ?1 and ?3 is reversed from ?1<?3 to ?1>?3 when ?1 increases.
