Publication number: 20240072203Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicants: SemiLEDs Corporation, SHIN-ETSU CHEMICAL CO., LTD.Inventors: Chen-Fu Chu, Shih-Kai Chan, Yi-Feng Shih, David Trung Doan, Trung Tri Doan, Yoshinori Ogawa, Kohei Otake, Kazunori Kondo, Keiji Ohori, Taichi Kitagawa, Nobuaki Matsumoto, Toshiyuki Ozai, Shuhei Ueda

Patent number: 10619759Abstract: A drain plug device is provided with a plug lid, a mounting member inserted in an overflow port, an operation handle provided corresponding to an opening of the mounting member at one end thereof so as to protrude from a surface of a sidewall, a transmission member configured to transmit a driving force generated by a pivoting operation of the operation handle to the plug lid side, and a handle moving mechanism capable of moving the operation handle. The handle moving mechanism is configured to make an amount of protrusion of the operation handle with respect to the surface of the sidewall when the drain port is open smaller than an amount of protrusion of the operation handle with respect to the surface of the sidewall when the drain port is closed. Whereby a good draining efficiency at the overflow port side is secured when draining is performed therethrough.Type: GrantFiled: October 6, 2016Date of Patent: April 14, 2020Assignee: JAPAN ALPHA CO., LTD.Inventors: Shinichi Ota, Kohei Kitagawa

Patent number: 9836175Abstract: A series of degree-of-approach data of the same object generated over a plurality of cycles of a detection operation is averaged in filter processing of the filter processing unit, and accordingly, the degree-of-approach data after averaging is acquired. Therefore, even in a case in which the degree-of-approach data is temporarily greatly changed due to an influence of noise, such a temporary change in the degree-of-approach data after averaging is suppressed. Further, response characteristics of a filter in the filter processing of the filter unit are changed according to a noise level which is detected by a noise detection unit. Accordingly, since appropriate filter processing according to the noise level is performed on the degree-of-approach data, the degree-of-approach data in which the influence of noise is effectively reduced is obtained.Type: GrantFiled: July 1, 2016Date of Patent: December 5, 2017Assignee: Alps Electric Co., Ltd.Inventors: Satoshi Nakajima, Satoshi Hayasaka, Hayato Miyagawa, Kohei Kitagawa
