Patent number: 9672856Abstract: A magnetic media having a lateral exchange control layer formed on a magnetic oxide layer of a magnetic recording layer. A cap layer is formed over the lateral exchange control layer. The lateral exchange control layer can be an alloy comprising Co and one or more of W, Ru, Hf, Ta, Nb and Fe. The lateral exchange control layer has the highest magnetic saturation moment among all the recording layers, and increases spacing between magnetic grains (e.g. increased non-magnetic boundary width), thereby reducing lateral exchange sigma. The presence of lateral exchange control increases signal to noise ratio and reduces bit error rate and increases areal density.Type: GrantFiled: November 19, 2015Date of Patent: June 6, 2017Assignee: HGST NETHERLANDS B.V.Inventors: Shun Tonooka, Masayoshi Shimizu, Miki Nishida, Hiroyuki Katada

Patent number: 9671212Abstract: A position sensor that detects operation positions of an operation member includes an element array having three stages, each including one or more detection elements. A detected subject is detected by each detection element in two adjacent upstream and downstream stages to determine an operation position of the operation member. Whenever the operation member is shifted by one operation position, the detected subject is moved relative to the element array by one stage. Each detection element outputs a detection result of the detected subject. The element array includes at least three detection elements of which the detection results change whenever the operation member is shifted by one operation position. A detection element in the upstream side stage detects the detected subject before the operation position shifting, and a detection element in the downstream side stage detects the detected subject after the operation position shifting.Type: GrantFiled: July 12, 2013Date of Patent: June 6, 2017Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventor: Masayoshi Iwata

Patent number: 9670914Abstract: In a check valve for a compressor, a valve element includes an abutting surface and an outer circumferential surface. A valve hole includes a large-diameter portion and a small-diameter portion. A communicating window has such a shape that an opening area thereof gradually becomes larger with increasing distance from a valve seat. The check valve has an open state, a fully closed state, and a buffering state. When the abutting surface separates from the large-diameter portion and the outer circumferential surface opens the communicating window, the open state is defined. When the abutting surface closes the large-diameter portion and the outer circumferential surface interrupts communication through the communicating window, the fully closed state is defined. When the abutting surface separates from the large-diameter portion and the outer circumferential surface interrupts communication through the communicating window, the buffering state is defined. The hunting phenomenon is suppressed.Type: GrantFiled: December 30, 2014Date of Patent: June 6, 2017Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Shingo Kumazawa, Kenji Yamamoto, Noriaki Satake, Masayoshi Kozawa

Publication number: 20170155194Abstract: A non-contact communication apparatus 100 includes an antenna resonant unit 110 and an antenna drive unit 130. In the antenna drive unit 130, for example, a measurement unit consisting of an differential amplifier A3 measures an output current from an oscillation unit 131. A control unit 140 detects a minimum value or maximum value of the output current. The resonant frequency is controlled by the use of an optimal control value corresponding to the minimum value or maximum value. Therefore, even if the resonant frequency fluctuates due to variations in antenna characteristics in manufacture or a usage environment or aging, satisfactory communication characteristics at a set resonant frequency can be obtained.Type: ApplicationFiled: July 9, 2015Publication date: June 1, 2017Inventor: Masayoshi Kanno
