Patent number: 5667127Abstract: A pneumatic nailing machine having a, driving depth controlling mechanism. The pneumatic nailing machine includes a push lever having a lower end in pressure contact with a workpiece and another end in association with a trigger. Vertical moving length of the push lever relative to a nose will change the driving depth. An eccentric body is rotatably supported on the main body. The eccentric body is positioned above the upper tip of the push lever and the upper position of the upper tip of the push lever is regulated by the eccentric body. If the eccentric body is angularly rotated to a first angular position, the push lever can be moved to its highest position for providing a minimum distance between the lower tip of the push lever and a lower tip of the nose to provide the maximum driving depth. If the eccentric body is angularly rotated to a second angular position, the distance between these tips become maximum to provide a minimum driving depth.Type: GrantFiled: March 7, 1995Date of Patent: September 16, 1997Assignee: Hitachi Koki Co., Ltd.Inventors: Kaoru Ichikawa, Kunio Yamamoto, Yoshitaka Akiba

Patent number: 4826641Abstract: In an injection molding process, male and female dies are first clamped together by a prescribed clamping force to provide surfaces defining a cavity of a prescribed extruded area therebetween. Then, a molten resin is injected at a prescribed injection pressure into the cavity until the cavity is filled with the molten resin. Subsequently, the molten resin filled in the cavity is held at a prescribed holding pressure, so that the resin within the cavity solidifies to produce a molded article. The injection pressure in the injecting step is controlled so as to decrease immediately before the cavity is filled with the molten resin to thereby prevent a pressure boost from occurring upon the termination of the injecting step. The holding pressure in the holding step is controlled in such a manner that a maximum of the pressure of the resin within the cavity in the holding step is higher than a maximum of the pressure of the resin within the cavity in the injecting step.Type: GrantFiled: August 17, 1988Date of Patent: May 2, 1989Assignee: Mitsubishi Kinzoku Kabushiki KaishaInventors: Yoshinobu Takeda, Kunio Yamamoto
