Patent number: 8502984Abstract: An optical measurement apparatus using an optical fiber to measure the characteristic of an object to be measured arranged along the circumference of a circle includes a first pulley, a second pulley which is turnable on its own axis at a second angular velocity while revolving about the first pulley at a first angular velocity, and the optical fiber which is held by the second pulley and projects detection light on the object to be measured and receives reflected light from the object to be measured. The first angular velocity and the second angular velocity are the same in magnitude and opposite in the direction. Occurrence of a twist in the optical fiber is suppressed, and therefore, the optical measurement apparatus is capable of measuring the characteristics of the object to be measured with high accuracy.Type: GrantFiled: July 21, 2011Date of Patent: August 6, 2013Assignees: Otsuka Electronics Co., Ltd., Toppan Printing Co., Ltd.Inventors: Hidehiro Atagi, Shuichi Yamada, Masanori Nakano, Eiji Kawata, Shuichi Akashi, Hiroyuki Kuroki

Patent number: 8327997Abstract: A transferred object rotating device includes a mounting plate having an opening corresponding to a shape of a transferred object and being capable of moving from a mounting position to a rotating position, a boost unit capable of moving up to pass through the opening of the mounting plate in the rotating position, and a rotation plate capable of rotating about a power transmission shaft. The mounting plate moves to the rotating position after the transferred object is mounted on the mounting plate to close the opening. The transferred object is lifted by upward movement of the boost unit. The transferred object rotates while being sandwiched between the boost unit and the rotation plate. The transferred object mounted on the mounting plate in the mounting position can be transferred to the rotating position by the mounting plate, and rotate in the rotating position.Type: GrantFiled: July 21, 2011Date of Patent: December 11, 2012Assignees: Otsuka Electronics Co., Ltd., Toppan Printing Co., Ltd.Inventors: Tamotsu Hamao, Akira Tanaka, Eiji Kawata, Shuichi Akashi, Hiroyuki Kuroki

Patent number: 5441097Abstract: A heat storage tank in which heat storage and heat discharge operations are carried out through heat-exchange between heat storage agent and heat transfer medium to store electric power as latent heat, including plural heat storage members which are arranged in a fill-up state in the heat storage tank, each heat storage member holding therein the heat storage agent which alternately repeats latent heat storing and discharging operations through solid-liquid phase variation thereof, and comprising an elongated hollow container formed of material which can keep itself in a hollow shape. The heat storage members are arranged with their open end portions faced up and so as to be spaced from one another at such an interval that the heat transfer medium can flow through gaps between neighboring heat storage members, then the heat storage agent is supplied through the open ends into the heat storage members, and then the heat transfer medium is supplied into the heat storage tank.Type: GrantFiled: May 16, 1994Date of Patent: August 15, 1995Assignee: Chiyoda CorporationInventors: Tetsuo Kanda, Eiji Kawata, Noboru Ikeda, Manami Miyazaki
