  • Publication number: 20110159701
    Abstract: The present disclosure provides a chemical liquid supply nozzle capable of suppressing the drying process of chemical liquid with a low cost. The chemical liquid supply nozzle is provided with a cutoff valve and a suction unit that sucks chemical liquid to a suction flow path at a nozzle main body connected to a front end of flow path member. Accordingly, the chemical liquid remaining at the downstream side of the cutoff valve after the chemical liquid is discharged, is sucked toward the upstream side of the cutoff valve and removed, to thereby suppress the drying and solidifying process of the chemical liquid at the chemical liquid flow path. Also, there is no need to block the chemical liquid flow path by sucking thinner at the downstream side of chemical liquid flow path, and the number of dummy dispense may be reduced, thereby reducing an overall operation cost of the process.

  • Publication number: 20100200531
    Abstract: A process for producing a heat- and pressure-resistant polyester bottle, comprising a primary blow-molding step of obtaining a primary molded article by biaxially stretch-blow-molding a preform of a polyester resin, a heat-treating step of obtaining a secondary molded article that is heat-shrunk by heat-treating the primary molded article, and a secondary blow-molding step of obtaining a finally molded article by biaxially stretch-blow-molding the secondary molded article, wherein the primary blow-molding step biaxially stretches the neck portion of the primary molded article to a size nearly the same as the neck portion of the finally molded article, and the heat-treating step does not cause the neck portion of the secondary molded article to be heat-shrunk.

  • Publication number: 20100163262
    Abstract: An electrical power tool (1) includes a motor (21), a casing (2), a piston (54), an intermediate shaft (41), a motion conversion mechanism (51A, 52, 52B; 51B, 53, 53B), and a plurality of types of anti-vibration mechanism (31,32,33; 55,40b). The motor (21) has a drive shaft (22). The casing (2) accommodates at least the motor (21). The piston (54) is driven by a rotary motion of the drive shaft (22). The intermediate shaft (41) extends parallel to the drive shaft (22) and is driven to rotate by the rotary motion of the drive shaft (22), the intermediate shaft (41) defining an axial direction. The motion conversion mechanism (51A, 52, 52B; 51B, 53, 53B) is disposed on the intermediate shaft (41) and is capable of moving in association with the intermediate shaft (41) for converting the rotary motion of the drive shaft (22) to a reciprocating motion.

  • Patent number: 7503402
    Abstract: A power tool suppressing expansion of the air in a chamber and preventing lubricant encapsulated in the chamber from being leaked outside of the chamber. A communication portion communicates a speed reduction chamber with a motor housing communicating with an atmosphere. A communication passage forming component made from an elastic material is fittingly inserted into the communication portion which forms a communication passage including a plurality of impediment portions. When the air containing lubrication component is passed through the communication passage, the air collides against the impediment portions, allowing grease component to be adhered to the impediment portions.
