Patent number: 8289810Abstract: A winding state evaluation method of a tape film includes a step of determining the attenuation rate of ultrasonic wave for the tape film (2) by sending an ultrasonic wave to the tape film (2) in parallel with the direction of the axis of rotation of a core (1) and receiving its reflected wave or transmitted wave, and a step of evaluating the winding state of the tape film (2) from the distribution state of the attenuation rate in the tape film (2). The method can judge the winding state of the tape film objectively by presenting its numerical representation concretely without relying upon sensual evaluation.Type: GrantFiled: March 19, 2008Date of Patent: October 16, 2012Assignee: Denki Kagaku Kogyo Kabushiki KaishaInventors: Hisatsugu Tokunaga, Masanori Higano

Publication number: 20030183553Abstract: In order to prevent impairment due to static electricity in a container for an electronic component, generation of static electricity itself has to be inhibited. The peeling static electrification amount of a cover tape should be from −9 to +9 nC when the cover tape has a surface resistivity of at least 1011 &OHgr;, or it should be from −3 to +3 nC when the cover tape has a surface resistivity of less than 1011 &OHgr;. In a carrier tape body, a side of a cover tape which faces an electronic component should have a composition containing a resin on the positive polarity side and a resin on the negative polarity side relative to a side of the electronic component which faces the cover tape in the series of frictional electrification. For the surface of a container to be in contact with an electronic component, a material which is less likely to generate static electricity should be employed.Type: ApplicationFiled: December 10, 2002Publication date: October 2, 2003Inventors: Tetsuo Fujimura, Takeshi Miyakawa, Mikio Shimizu, Satoshi Yokoyama, Masanori Higano, Masanori Ishii, Kazuhiro Kosugi, Takashi Tomizawa
