Publication number: 20100139775Abstract: A pressure type flow control device enabling a reduction in size and an installation cost by accurately controlling the flow of a fluid in a wide flow range. Specifically, the flow of the fluid flowing in an orifice (8) is calculated as Qc=KP1 (K is a proportionality factor) or Qc=KP2m(P1?P2)n (K is a proportionality factor and m and n are constants) by using a pressure P1 on the upstream side of the orifice and a pressure P2 on the downstream side of the orifice. A fluid passage between the downstream side of the control valve of the flow control device and a fluid feed pipe is formed of at least two or more fluid passages positioned parallel with each other. Orifices with different fluid flow characteristics are interposed in the fluid passages positioned parallel with each other. For the control of the fluid in a small flow area, the fluid in the small flow area is allowed to flow to one orifice.Type: ApplicationFiled: June 22, 2006Publication date: June 10, 2010Applicants: FUJIKIN INCORPORATED, NATIONAL UNIVERSITY CORPORATION TOHOKU UNIVERSITY, TOKYO ELECTRON LTD.Inventors: Tadahiro Ohmi, Masahito Saito, Shoichi Hino, Tsuyoshi Shimazu, Kazuyuki Miura, Kouji Nishino, Masaaki Nagase, Katsuyuki Sugita, Kaoru Hirata, Ryousuke Dohi, Takashi Hirose, Tsutomu Shinohara, Nobukazu Ikeda, Tomokazu Imai, Toshihide Yoshida, Hisashi Tanaka

Patent number: 6336417Abstract: An apparatus according to the present invention comprises a sensor and a control circuit. The sensor is disposed near a needle drop portion of a needle plate and detects the quantity of light transmitted through cloths passing over the needle plate. The control circuit determines defective sewing from increase and decrease of said light quantity. The control circuit comprises means for storing the averaged value of the light transmitted in a few stitches of initial sewing operation, and means for determining defective sewing continuously from the initial sewing operation by comparing the average value with the value of the light transmitted and detected each time. Thus, it is possible to immediately start the practical sewing operation without taking time for test sewing or other extra jobs even when every cloth to be sewn is different in properties.Type: GrantFiled: August 7, 2001Date of Patent: January 8, 2002Assignee: Pagasus Sewing Machine Mfg. Co., Ltd.Inventors: Toshio Kawahito, Masahito Saito
