Patent number: 11917917Abstract: A thermoelectric conversion element that has a power generation layer containing an iron-aluminum based magnetic alloy material containing equal to or more than 70 weight percent of iron and aluminum in total. The power generation layer generates an electromotive force, due to an anomalous Nernst effect that develops in the magnetic alloy material in response to a temperature gradient applied thereto, in a direction intersecting both the magnetization direction of the magnetic alloy material and the direction of the applied temperature gradient.Type: GrantFiled: December 13, 2019Date of Patent: February 27, 2024Assignee: NEC CORPORATIONInventors: Akihiro Kirihara, Yasutomo Omori, Ryohto Sawada, Masahiko Ishida, Koichi Terashima, Yuma Iwasaki, Hiroko Someya

Patent number: 8960749Abstract: A vacuum suction apparatus is equipped with a body having a supply port, and a pad provided on a lower portion of the body to which a workpiece can be attracted under suction. The pad is constituted from a base plate accommodated in a space of the body, a flexible intermediate plate provided on a lower portion of the base plate, and a suction sheet body disposed on a lower portion of the intermediate plate and having a sheet that attracts the workpiece under suction. In addition, the base plate, the intermediate plate and the suction sheet body are stacked along an axial direction of the body. The rigidity of the base plate is highest, whereas the rigidities of the intermediate plate and the suction sheet body are lower in this order, and the flexibilities thereof are greater in this order from the base plate.Type: GrantFiled: September 10, 2012Date of Patent: February 24, 2015Assignee: SMC Kabushiki KaishaInventors: Yoshihiro Fukano, Shuzo Sakurai, Masahiko Someya

Publication number: 20060207247Abstract: An actuator comprises a driving section driven and rotated by a supplied current, a pump mechanism driven by a driving force supplied from the driving section to suck and discharge pressure oil, and a cylinder mechanism having a piston displaceable by the pressure oil supplied from the pump mechanism. When a pressure of the pressure oil is at or greater than a predetermined value in the cylinder mechanism, a relief valve provided in the pump mechanism is opened to thereby discharge the pressure oil into a pressure oil-charging chamber of the pump mechanism. Pressure within a first or second cylinder chamber of the cylinder mechanism and into which the pressure oil is introduced is maintained substantially constant.Type: ApplicationFiled: March 17, 2006Publication date: September 21, 2006Applicant: SMC Kabushiki KaishaInventors: Shigekazu Nagai, Akio Saitoh, Masahiko Someya, Masaru Saitoh

Patent number: 7109412Abstract: A cable, which includes a plurality of tubes disposed continuously in the height direction, has one end which is fixed to a first cable-connecting section disposed at one end of a body of an electric actuator. The cable has the other end which is connected to a second cable-connecting section connected to a slider which is displaceable along the axis under the driving action of a rotary driving source. The cable is installed substantially horizontally with respect to the body. The dimension in the height direction is large, and the dimension in the thickness direction is small.Type: GrantFiled: February 20, 2003Date of Patent: September 19, 2006Assignee: SMC Kabushiki KaishaInventors: Shigekazu Nagai, Toru Sugiyama, Masahiko Someya
