Publication number: 20240157588Abstract: A handle includes a casing grippable by a user with a hand and fingers. The casing incorporates a first vibrating body and a second vibrating body. A control device is capable of generating a first sense of force in a first direction by controlling a vibration pattern of the first vibrating body. The control device is capable of generating a second sense of force in a second direction by controlling a vibration pattern of the second vibrating body. Then, the control device can control the vibration pattern of the first vibrating body and the second vibrating body so that the first direction and the second direction are different directions and an imaginary line headed toward the first direction from the first vibrating body and an imaginary line headed toward the second direction from the second vibrating body are not located on the same straight line.Type: ApplicationFiled: January 25, 2024Publication date: May 16, 2024Inventors: Shinji OKAWA, Koji OSAKI

Publication number: 20240157539Abstract: A handle includes a housing that includes a first vibrating body and a second vibrating body. A control device is able to generate a first force sensation in a first direction by controlling a vibration pattern of the first vibrating body and to generate a second force sensation in a second direction by controlling a vibration pattern of the second vibrating body. The control device is able to control so as to set the first direction and the second direction are the same. The control device is able to control the vibration pattern of the first vibrating body and the vibration pattern of the second vibrating body so as not to allow a virtual line directed from the first vibrating body in the first direction and a virtual line directed from the second vibrating body in the second direction to be positioned on a single line.Type: ApplicationFiled: January 25, 2024Publication date: May 16, 2024Inventors: Shinji OKAWA, Koji OSAKI

Patent number: 11946847Abstract: An extracellular potential measurement device includes multiple insulating films each of which is made from an electric insulating material, the insulating films being stacked and bonded to each other; and multiple electrode wires each of which is made from an electroconductive material, the electrode wires being arranged in multiple heights. Each of the electrode wires is interposed between an upper insulating film and a lower insulating film. Each of the insulating films, except for a lowermost insulating film, has an opening penetrating the insulating film. The opening in a lower insulating film has a size that is less than that of the opening in an upper insulating film, the openings in the insulating films being overlapped to form a recess having a size reducing downward, the recess being adapted to store a collection of cells. Each of the electrode wires has an end that is located near an opening in an insulating film that is immediately below the electrode wire, the ends being exposed in the recess.Type: GrantFiled: October 1, 2020Date of Patent: April 2, 2024Assignees: NOK CORPORATION, THE UNIVERSITY OF TOKYOInventors: Takayuki Komori, Keiichi Miyajima, SooHyeon Kim, Teruo Fujii, Shinji Okawa

Patent number: 7855129Abstract: A direct bonded SOI wafer having an entire buried oxide film layer covered and not exposed is manufactured by: (A) forming a laminated body by laminating a semiconductor wafer and a support wafer via an oxide film; and (B) forming a thin-film single crystal silicon layer on the support wafer using a buried oxide film layer by film-thinning the semiconductor wafer to a predetermined thickness. In a process (C) the entire buried oxide film layer is covered by a main surface on the laminating side of the support wafer and the single crystal silicon layer. The covering of the entire buried film layer is carried out by, between process (A) and (B), removing the oxide film formed on the circumferential end edge of the main surface on the laminating side and the chamfered portion to leave the oxide film only on the laminated surface except the circumferential end edge.Type: GrantFiled: May 12, 2010Date of Patent: December 21, 2010Assignee: Sumco CorporationInventors: Etsurou Morita, Shinji Okawa, Isoroku Ono

Then, an ion implanted area (23b) is formed inside the layer transferred wafer (12) by implanting ions into a second main surface (12c) of the first layer transferred wafer (12) on the side opposite to a separated surface (12a), and a second laminated body (26) in which the main surface (12c) of the wafer (12) is laminated onto a second support wafer (24) is subjected to heat treatment so as to obtain a thick second layer transferred wafer (22). And then, both surfaces of the layer transferred wafer (22) are polished to obtain a regenerated wafer (32).Type: ApplicationFiled: December 21, 2006Publication date: June 28, 2007Inventors: Etsurou Morita, Shinji Okawa, Isoroku Ono
