Patent number: 11228128Abstract: The object is to provide a technology that can prevent a spring electrode from being dissolved and broken upon a short circuit in a semiconductor chip. A spring electrode includes a main body. The main body is a tubular conductor, and varies in diameter in a longitudinal direction so that a side surface has bellows. Since the main body of the spring electrode does not include an edge portion, the local concentration of a short-circuit current that flows through the spring electrode upon a short circuit in a semiconductor chip can be reduced. This can prevent the spring electrode from being dissolved and broken.Type: GrantFiled: August 28, 2017Date of Patent: January 18, 2022Assignee: Mitsubishi Electric CorporationInventors: Shigeto Fujita, Yoshikazu Yaji

Patent number: 9557621Abstract: A liquid crystal display device is provided with a liquid crystal cell member, a light regulating member, a reflective polarizing member, and a control unit. The liquid crystal cell member has a first liquid crystal layer. An optical transmittance of the light regulating member changes with the application state of a second voltage. The reflective polarizing member transmits specific polarized light and reflects other polarized light. The polarization direction of light that is incident on the reflective polarizing member from the first liquid crystal layer is the same as the polarization direction of light transmitted by the reflective polarizing member. The control unit alters the application state of the second voltage in such a manner that the transmittance of the light regulating member when a backlight unit is on is higher than the transmittance of the light regulating member when the backlight unit is off.Type: GrantFiled: December 13, 2013Date of Patent: January 31, 2017Assignee: Mitsubishi Electric CorporationInventors: Akihiro Nagase, Yoshikazu Yaji, Tomohiro Sasagawa, Atsushi Michimori
