Patent number: 10195774Abstract: An air ejector of a resin molding device includes air passages, air outlets through which air is injected, movable valves biased by bias members to close the air outlets, accommodation spaces in which the movable valves are movably contained, an air supply path through which air is supplied from an air supply source, and a pressure sensor to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.Type: GrantFiled: June 6, 2013Date of Patent: February 5, 2019Assignee: CALSONIC KANSEI CORPORATIONInventors: Yoshihito Kobune, Akihito Kanemasa, Kenjiro Sugimoto, Kunio Shimada

Publication number: 20150190956Abstract: Provided are a resin molding device and a resin molding method for easily removing a thin and soft resin molded product from a mold with a good finish by sensing an operation failure of an air ejector reliably. An air ejector (22) of a resin molding device (20) comprises air passages (24a, 24b), air outlets (26a, 26b) through which air is injected, movable valves (27a, 27b) biased by bias members (29a, 29b) to close the air outlets (26a, 26b), accommodation spaces (28a, 28b) in which the movable valves (27a, 27b) are movably contained, an air supply path (32) through which air is supplied from an air supply source (33), and a pressure sensor (35) to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.Type: ApplicationFiled: June 6, 2013Publication date: July 9, 2015Inventors: Yoshihito Kobune, Akihito Kanemasa, Kenjiro Sugimoto, Kunio Shimada

Patent number: 8418572Abstract: A three-dimensional cam mechanism capable of selecting a cam guide surface shape freely to improve the degree of freedom for selecting a target locus on the follower side, transmitting power between orthogonal axes and performing a reversible operation. A three-dimensional cam guide surface (2 (3)) is formed in a cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the cam (1) is translated into the swinging movement at the other end of the follower side link (4). Thus, smooth operations of the cam are obtained by the selection of the shape of a supporting member and by the free design of the cam guide surface shape, without being limited to the power transmission between the orthogonal axes or followed by backlash.Type: GrantFiled: May 28, 2008Date of Patent: April 16, 2013Assignee: National University Corporation Fukushima UniversityInventors: Takayuki Takahashi, Seong Hee Jeong, Yoshihito Ozawa, Kunio Shimada, Yaoyang Zheng, Kazuhiko Fukuda

Publication number: 20100116072Abstract: An object of the present invention is to provide a three-dimensional cam mechanism, which is capable of selecting a cam guide surface shape freely to drastically improve the degree of freedom for selecting a target locus on the follower side, transmitting not only a power between orthogonal axes but also a strong and reliable power, and performing a reversible operation. The present invention is configured such that a three-dimensional cam guide surface (2 (3)) is formed in a three-dimensional cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the three-dimensional cam (1) is translated into the swinging movement at the other end of the follower side link (4).Type: ApplicationFiled: May 28, 2008Publication date: May 13, 2010Applicant: National Univerisity Corporation Fukushima UniversityInventors: Takayuki Takahashi, Seong Hee Jeong, Yoshihito Ozawa, Kunio Shimada, Yaoyang Zheng, Kazuhiko Fukuda

Publication number: 20090035556Abstract: The invention provides an electrical conductive composite material having superior thermal and electrical conductive performances. The electrical conductive composite material can be obtained by curing a mixture of a liquid elastic polymeric material and a magnetic compound fluid, which is prepared by dispersing Ni powder and Cu powder in a magnetic fluid, in a magnetic field. In the electrical conductive composite material, network cluster is formed by aggregation of Cu particles and Ni particles.Type: ApplicationFiled: August 1, 2008Publication date: February 5, 2009Inventors: Kunio Shimada, Takayuki Takahashi, Yoshihito Ozawa, Kazuhiko Fukuda, Yaoyang Zheng, Seong Hee Jeong

Patent number: 6964324Abstract: A damper in which magnetic particles are discouraged from settling irrespective of the kind of a magnetic fluid is provided. A damper is constituted of a vessel in which the magnetic fluid is accommodated and a slider (piston). As the piston, one that is made of a laminated body of a paramagnetic substance and a non-magnetic substance is used. When thus constituted, the magnetic particles stick to the piston. Accordingly, whatever magnetic fluid is used, the particles do not settle. The laminated body that is used as the piston has the non-magnetic substance at both ends thereof. When the laminated body is thus constituted, the magnetic particles sticks uniformly. When the laminated body has the magnetic substance at both ends, magnetic particles stick to both ends needle-like.Type: GrantFiled: June 6, 2003Date of Patent: November 15, 2005Assignee: Tohoku Techno Arch Co., Ltd.Inventors: Kunio Shimada, Hideto Kanno

Patent number: 5028898Abstract: In a proposed color cathode-ray tube with deflection yoke, adjustment of static convergence and purity is performed by controlling the polarities and magnetization forces of a plurality of pole pieces made of metal alloy circumferentially held around the outer periphery. Tap bolts pressing the external wall of a funnel nearly in the perpendicular direction are so disposed on a deflection yoke mounting member as to be adjacent to the funnel of the color cathode-ray tube. The tap bolts press the funnel to fix the deflection yoke.Type: GrantFiled: August 16, 1989Date of Patent: July 2, 1991Assignee: Hitachi, Ltd.Inventors: Michio Tsukii, Kunio Shimada, Eiichi Nishiyama, Takumi Karasawa, Fumiaki Yonai, Hiroshi Yoshioka, Takashi Atobe
