Abstract: The resin molding machine is capable of cleaning a resin molding die while performing a molding action without stopping the molding action and capable of securely removing contaminations from the resin molding die. The resin molding machine comprises: a press unit including a resin molding die; and a cleaning unit for cleaning a molding face of the resin molding die. The cleaning unit has an energy ray irradiation section, which irradiates an energy ray to the molding face of the resin molding die so as to easily peel off a contamination, which has been stuck on the molding face during a molding action, from the molding face. The contamination is stuck onto resin of a molded product when the product is resin-molded, so that the molded product is released from the resin molding die together with the contamination.

Abstract: Low-pressure fire-extinguishing liquid is converted into mist. A fire-extinguishing spray nozzle (10) comprises a main body (30) and an obstacle (36). The main body (30) has a port (40) for radially injecting the fire-extinguishing liquid. The obstacle (36) has an opposing surface (60) and is opposite to the port (40). The opposing surface (60) is arranged within a radial-injection region (102) of the fire-extinguishing liquid radially injected from the port (40). One part of the fire-extinguishing liquid radially injected from the port (40) collides with the opposing surface (60) and is reflected therefrom. The other part of the fire-extinguishing liquid radially injected from the port (40) passes around the opposing surface (60). The one part of the fire-extinguishing liquid is reflected from the opposing surface (60) and the other part passes around the opposing surface (60).

Abstract: Low-pressure fire-extinguishing liquid is converted into mist. A fire-extinguishing spray nozzle (10) comprises a main body (30) and an obstacle (36). The main body (30) has a port (40) for radially injecting the fire-extinguishing liquid. The obstacle (36) is arranged within a radial injection region (102) of the fire-extinguishing liquid radially injected from the port (40). The obstacle (36) has an outer peripheral surface formed in the shape of a truncated-conical inclined surface (62). This enables the fire-extinguishing liquid (70) radially injected from the port (40) and passing around the obstacle (36) to collide with the fire-extinguishing liquid (72) radially injected from the port (40) and reflected from the inclined surface (62) so as to produce mist (74) of fire-extinguishing liquid. When producing the mist (74) by such an action, the fire-extinguishing liquid radially injected from the port (40) may have a low pressure.

Abstract: A shape of a screw for fastening thin-sheets or thin-walled parts is characterized in that a value of ratio (P/D) of a pitch (P) to each of nominal diameters (D) of coarse thread in the shape of screw thread is reduced as compared to values of ratio of pitches to a corresponding nominal diameter of coarse thread in known kinds of screw thread standard, and the multiple number of thread start is set to 2 or more. Thus, for the thin-sheets and thin-walled parts in which three engaging ridges of screw threads cannot be secured when current metric coarse thread screw is used, the shape of the screw thread advantageous in strength and excellent in loose torque after vibration can be provided, since screw fastening is stabilized more than a case in which the metric coarse thread screws are used.
