Publication number: 20190143563Abstract: Provided is a dust stop device for a sealed kneader, the device being capable of excellent supply of lubricating oil. The sealed kneader includes a pair of rotors and a supporting member. The dust stop device includes a rotating ring attached to each rotor and a stationary ring attached to the supporting member. Both the rings have respective contact surfaces which make surface contact with each other. The stationary ring has a lubricating-oil supply portion with a through-hole. A part of the through-hole, the part including a part opened in the contact surface, is a long hole extending along a circumferential direction of rotation of the rotating ring.Type: ApplicationFiled: April 27, 2017Publication date: May 16, 2019Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Naofumi KANEI, Koichi MIYAKE, Hikaru HAMADA

Patent number: 9267860Abstract: The present invention provides a tire balance measuring device capable of minimizing the influence exerted on a measured value due to an inclination of a lock shaft even when the lock shaft (fitted shaft) is inclined in a random direction at an angle created by a gap corresponding to a fitting allowance every time a tire is supplied with gas. The tire balance measuring device of this invention comprises a sensor for measuring the inclination of the lock shaft, and a computing unit for computing an amount of change in a unbalance of the tire from an output value received from the sensor after the tire is supplied with gas, and correcting a result of measuring a balance of the tire using the computed amount of change in the unbalance.Type: GrantFiled: June 26, 2013Date of Patent: February 23, 2016Assignee: Kobe Steel, Ltd.Inventors: Naofumi Kanei, Maiko Nakayama, Michiya Kurohashi

Patent number: 7969459Abstract: A thermal printhead (A) includes an insulating substrate (1), a heating resistor (2) provided on the substrate (1) and a protective film (4) covering the heating resistor (2). The protective film (4) is made up of a first layer (41), a second layer (42) and a third layer (43). The first layer (41) is held in contact with the heating resistor (2). The second layer (42) covers the first layer (41). The second layer (42) is harder than the first layer (41) and has a higher thermal conductivity than that of the first layer (41). The third layer (43) is the outermost layer and covers the second layer (42). The third layer (43) is harder than the second layer (42) and thinner than the second layer (42).Type: GrantFiled: February 21, 2008Date of Patent: June 28, 2011Assignee: Rohm Co., Ltd.Inventors: Naofumi Kanei, Takumi Yamade
