Patent number: 11255581Abstract: A free piston Stirling refrigerator of the present invention has a cylinder provided inside a casing; a piston and a displacer that are provided in a way such that they are capable of reciprocating inside the cylinder; a linear motor for reciprocating the piston; and a control unit for controlling the operation of the linear motor. Particularly, the control unit has an inverter circuit for generating an alternating current with a given frequency and then supplying the alternating current to the linear motor; a current detection circuit for detecting the current outputted from the inverter circuit; and a control circuit for controlling the output from the inverter circuit based on a turbulence in the current detected by the current detection circuit. Thus, collisions between the piston and the displacer (i.e. hitting) can be restricted through an inexpensive configuration and a simple control.Type: GrantFiled: December 16, 2020Date of Patent: February 22, 2022Assignee: Twinbird CorporationInventors: Mineyuki Inoue, Kazuya Tsuji, Jun Komada

Patent number: 10541645Abstract: A solar cell module includes a solar cell panel, a frame member, and an adhesive. The solar cell panel has a front surface, a back surface and a lateral surface. The frame member is located along an outer peripheral part of the solar cell panel, and includes a fitting section with the outer peripheral part fitted therein. The adhesive is located in a space in the fitting section, and bonded to the outer peripheral part. The adhesive includes a pressure-sensitive first adhesive and a curable second adhesive. The curable second adhesive exists at a position different from a position at which the first adhesive exists, in a direction along the longitudinal direction of the frame member.Type: GrantFiled: July 27, 2017Date of Patent: January 21, 2020Assignee: KYOCERA CORPORATIONInventors: Toshiyuki Yuasa, Kazushi Motonaga, Jun Komada, Keita Suzuki
