Patent number: 10509525Abstract: A touch panel includes a first sheet and a second sheet that are disposed opposing each other. A first conductive path and a second conductive path are formed facing each other on main surfaces of the first sheet and the second sheet, respectively. The second conductive path is spaced apart from the first conductive path when viewed in the normal direction of the first sheet. On the main surface of the second sheet, pressure-detecting conductive paths electrically connected to the second conductive path are arranged. The pressure-detecting conductive paths intersect the first conductive path as viewed in the normal direction. Structures are disposed on a second sheet main surface not opposing the first sheet, and cause flexing of the corresponding pressure-detecting conductive path to contact the first conductive path when pressed down.Type: GrantFiled: August 2, 2016Date of Patent: December 17, 2019Assignee: Mitsubishi Electric CorporationInventors: Yoshinori Nakajima, Yoshiaki Koizumi, Soichiro Kurokawa

Patent number: 10254002Abstract: An outdoor unit and an indoor unit communicate with each other. The outdoor unit includes a communication circuit that outputs a pulse signal to be transmitted to the indoor unit. The indoor unit includes a communication circuit that receives the pulse signal transmitted by the outdoor unit. An air conditioner 100 includes at least one photocoupler to transfer to the communication circuit the pulse signal output by the communication circuit. The communication circuit transmits a pulse signal with a first polarity and a pulse width corrected to be shorter by a predefined correction time than a predefined reference pulse width of the pulse signal.Type: GrantFiled: November 4, 2014Date of Patent: April 9, 2019Assignee: Mitsubishi Electric CorporationInventors: Soichiro Kurokawa, Yoshiaki Koizumi

Patent number: 8836670Abstract: An image processing apparatus which is allowed to achieve a higher speed of a labeling process than ever before is provided. Sequential scanning is performed on pixels in a picked-up image represented by binarized data Din. Moreover, during the sequential scanning, while label information representing an identification number for each connected region in the picked-up image is, as occasion arises, allocated to a target pixel based on values of pixel data of the target pixel and neighboring pixels thereof, additional information (position information and area information) for each connected region corresponding to each label information is updated as occasion arises. Thereby the label information, the position information and the area information about the whole picked-up image are obtained by one sequential scanning process.Type: GrantFiled: July 28, 2009Date of Patent: September 16, 2014Assignee: Japan Display, Inc.Inventors: Ryoichi Tsuzaki, Soichiro Kurokawa, Tsutomu Harada, Kazunori Yamaguchi, Mitsuru Tateuchi
