Patent number: 8650971Abstract: A simply-structured initial slippage detection mechanism. When a contact member comes in contact with a contact receiving member via a pressure-sensitive conductive sheet, it is confirmed, on the basis of a change in resistivity of the pressure-sensitive conductive sheet and in response to a detection signal transmitted from the pressure-sensitive conductive sheet, that initial slippage has occurred right before the occurrence of slippage displacement, at a time when a high-frequency waveform component generated right before the occurrence of the slippage displacement of the contact member exceeds a predetermined threshold value. Therefore, it is possible to realize a slippage detection device whose slippage detection section is smaller, more lightweight and thinner.Type: GrantFiled: May 14, 2010Date of Patent: February 18, 2014Assignees: The University of Electro-Communications, Inaba Rubber Co., Ltd.Inventors: Makoto Shimojo, Seiichi Teshigawara

Patent number: 8490501Abstract: A complex sensor comprises a touch sensor and a proximity sensor. The touch sensor comprises a flexible pressure-sensitive sheet covering a fingertip portion. The pressure-sensitive sheet comprises a front surface film and a rear surface film composed of a flexible conductive material, an intermediate film which is sandwiched between the films in a state in which the intermediate film is electrically connected and which is composed of pressure-sensitive conductive rubber, and first to fourth electrode terminals formed on the front surface and rear surface films. The size of a load acting on the pressure-sensitive sheet and the center position of the load can be detected based on the terminal voltage. A through-hole is formed in the pressure-sensitive sheet such that the sensing surface of the proximity sensor is exposed, thus the approach of a holding object can be detected.Type: GrantFiled: May 29, 2008Date of Patent: July 23, 2013Assignee: Harmonic Drive Systems Inc.Inventors: Junji Koyama, Makoto Shimojo, Yoshitomo Mizoguchi

Publication number: 20120067142Abstract: What is proposed is simply-structured initial slippage detection means. When a contact member (5) comes in contact with a contact receiving member (2) via a pressure-sensitive conductive sheet (3A), it is confirmed, on the basis of a change in resistivity of the pressure-sensitive conductive sheet (3A) and in response to a detection signal (S1) transmitted from the pressure-sensitive conductive sheet (3A), that initial slippage has occurred right before the occurrence of slippage displacement, at a time when a high-frequency waveform component (VpX) generated right before the occurrence of the slippage displacement of the contact member (5) exceeds a predetermined threshold value. Therefore, it is possible to realize a slippage detection device whose slippage detection section is smaller, more lightweight and thinner.Type: ApplicationFiled: May 14, 2010Publication date: March 22, 2012Applicants: INABA RUBBER CO., LTD., THE UNIVERSITY OF ELECTRO-COMMUNICATIONSInventors: Makoto Shimojo, Seiichi Teshigawara
