Patent number: 10350645Abstract: An article rejecting system includes: a conveyance unit that conveys an article along a conveying direction; a detection unit that detects the article which is conveyed by the conveyance unit; a rejecting unit that is provided on a downstream side of the detection unit in the conveying direction and performs a rejecting motion for rejecting the article which is conveyed by the conveyance unit; a control unit that controls the rejecting unit such that the rejecting motion is performed at a predetermined automatic timing when the detection unit detects the article; and an input unit that accepts input of a manual operation for causing the rejecting unit to perform the rejecting motion at a manual timing. The control unit sets the automatic timing based on the manual timing, if the input unit accepts the input of the manual operation when the detection unit detects the article.Type: GrantFiled: February 23, 2018Date of Patent: July 16, 2019Assignee: ISHIDA CO., LTD.Inventors: Shoji Suda, Emi Mizuno, Ken Iwakawa, Kohei Hayashida, Yuzuru Yamada

Patent number: 4903939Abstract: A pneumatically-operated valve in which a valve actuator is formed of two separate parts: a driving member having a plurality of sealed pistons fixed to a piston rod in series to be operated by air pressure, and a valve operating member which comes into contact with a clean fluid and which does not have any soft substances such as O-rings which are likely to be impaired by ultrasonic cleaning. The valve facilitates the cleaning of the members during the process of manufacture and furthermore can provide a great deal of output for its size without contaminating the clean fluid during use.Type: GrantFiled: April 24, 1989Date of Patent: February 27, 1990Assignee: Fujikura Rubber, Ltd.Inventors: Ryozo Ariizumi, Masakuni Kainuma, Toshikazu Aoki, Shoji Suda, Mitsunori Hoshi, Takashi Ejiri

Patent number: 4875500Abstract: A pilot operated directional control valve having a diaphragm held between a passage block which has a feeding port, at least one loading port and at least one discharge port, and an opposed control block which has pilot pressure passages. The ports of the passage block open into the end face of the passage block adjacent to the control block through respective fluid passages. The pilot pressure is exerted on the diaphragm by the pilot pressure passages to control the fluid connection between the ports of the passage block. The fluid passages are located in a concentric arrangement.The diaphragm has a center valve portion with an annular valve portion therearound. The two valve portions can be independently controlled by the pilot pressure acting thereon to control the fluid connection between the two adjacent fluid passages.Type: GrantFiled: March 16, 1988Date of Patent: October 24, 1989Assignee: Fujikura Rubber Ltd.Inventors: Ryozo Ariizumi, Masakuni Kainuma, Shoji Suda, Toshikazu Aoki, Takashi Ejiri, Masao Kojima, Mitsunori Hoshi
