The concrete composition comprises: a microcapsule; cement; and at least one type of aggregate. The microcapsule is provided with a core-shell structure having i) a core made of a water repellent organosilicon material selected from the group consisting of organosilanes, organosilane partial condensation products, and branched siloxane resins, and ii) a shell made of a silicon-based network polymer containing silica units. The concrete composition contains 0.01 to less than 0.5 parts by weight of microcapsules per 100 parts by weight of cement. Thereby, a precast concrete molded body can be provided, having high strength, as well as at least one of the following properties: air content stability, substance penetration prevention, and freeze-thaw resistance.Type: ApplicationFiled: March 17, 2021Publication date: May 11, 2023Inventors: Taro MINATO, Katsuhiko TANIGUCHI, Sakae USHIJIMA, Hideo MATSUZAKI, Masatomo MAKIGUCHI, Motoaki IMURA, Hideyuki MORI

Patent number: 10857946Abstract: A shutter is formed to be capable of bending in a sliding direction, and slides along a pair of guide grooves including a curved portion at one portion thereof, the guide grooves being provided on two sides, facing each other, of an opening of a device main member and a shutter storage side, to open and close the opening. The shutter includes a shutter base material sliding along the guide grooves in a state wherein corresponding portions fit into the guide grooves; and a hinge base material disposed on an outer face of the shutter base material. Also, the hinge base material is a sheet formed by a continuous fiber reinforced plastic or a sheet produced using a pre-preg material.Type: GrantFiled: September 8, 2016Date of Patent: December 8, 2020Assignee: NIFCO INC.Inventors: Katsuhiko Taniguchi, Seonkyu Lim

Patent number: 8485585Abstract: A lock device includes a cam portion including a stationary-side cam; a rotor including a movable-side cam; a slide groove; a slide projection; an engagement projection; and a lock groove, in which the movable-side cam is disengaged from the stationary-side cam, so that the rotor rotates so as to allow the engagement projection that has been fitted in the lock portion to disengage from the lock portion. The urging device includes a spring, and a sleeve inserted to pass through a lower-side rod portion, positioned between the rotor and the spring, and also restricting a movement of the rod in a sliding direction in a lock position of the lock device (for example, a lock groove and an engagement projection, and the like).Type: GrantFiled: June 24, 2010Date of Patent: July 16, 2013Assignee: Nifco Inc.Inventors: Katsuhiko Taniguchi, Katsuhito Kurachi

Patent number: 5380181Abstract: A control device for an electric injection molding machine designed to advance and retract a screw in a heating cylinder by an injection motor includes a screw position detector for detecting a screw position to output a screw position detection signal, a speed pattern generator for generating a speed setting pattern signal which indicates relationship between time and screw speed. An integration unit integrates the speed setting pattern signal to obtain a moving stroke of the screw. And a generation unit generates a position instruction signal on the basis of the moving stroke and a screw position when injection is initiated. To generate a speed instruction signal, the screw position detection signal is subtracted from the position instruction signal as a manipulated variable of feedback and the speed setting pattern signal is applied to the position instruction signal as a manipulated variable of feed forward. Thus, accuracy at the speed changing positions can be improved, thus improving operability.Type: GrantFiled: June 21, 1993Date of Patent: January 10, 1995Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Kazuo Hiraoka, Katsuhiko Taniguchi

Patent number: 5259272Abstract: In a continuously variable transmission of the type in which a speed change ratio is changed in a manner that the radius of rotation of a belt wound around a drive pulley and a driven pulley is varied by changing the width of a groove between the pulley parts of each pulley with an oil pressure. A control means for controlling an oil pressure in various control modes shifts the control mode from a hold mode to a start mode, when a driver manipulates a vehicle carrying the continuously variable transmission with his intention to start the vehicle, and an amount of discharge flow of an oil pump for generating an oil pressure exceeds a preset value. The safety factor in a stationary state is calculated using the effective tension of the CVT belt, secondary side oil pressure, and the speed change ratio.Type: GrantFiled: September 25, 1992Date of Patent: November 9, 1993Assignees: Mitsubishi Denki K.K., Suzuki Motor Corp.Inventors: Hiroaki Yamamoto, Yoshinori Yamashita, Katsuhiko Taniguchi
