Patent number: 11424053Abstract: A ceramic feedthrough assembly has a feedthrough interface sleeve brazed to a ceramic feedthrough body and a housing interface sleeve brazed to the feedthrough interface sleeve. The housing interface sleeve is configured to be integrated within an electronic device and welded to a metal housing to form a hermetically sealed electronic device. The ceramic feedthrough has at least one embedded electrical conductor extending from a first location on the ceramic feedthrough body to a second location on the ceramic feedthrough body. The feedthrough interface sleeve is positioned around the ceramic feedthrough body between the first location and the second location and brazed to the wrap-around metallization. When the metal housing is welded to the housing interface sleeve, the ceramic feedthrough assembly facilitates connection to an electronic circuit hermetically sealed in the electronic device with the metal housing.Type: GrantFiled: April 21, 2021Date of Patent: August 23, 2022Assignee: Kyocera International, Inc.Inventors: Franklin Kim, Mark Eblen, Hiroshi Makino, Shinichi Hira

Patent number: 11235453Abstract: An electric working machine in one aspect of the present disclosure includes a motor, a controller, and a setter. The controller is configured to change a rotational state of the motor, in response to an establishment of a condition for change after the motor is initiated, from a low speed rotation to a high speed rotation. The setter is configured to set, based on a situation in the motor in the low speed rotation, a control variable of the motor in the high speed rotation and/or the condition for change.Type: GrantFiled: August 2, 2018Date of Patent: February 1, 2022Assignee: MAKITA CORPORATIONInventors: Yoshitaka Ichikawa, Goshi Ishikawa, Shinichi Hira, Yasuhito Kawai, Masahiro Watanabe, Takuya Kusakawa

Patent number: 10410959Abstract: Package deflection and mechanical stress of microelectronic packaging is minimized in a two step manufacturing process. In a first step, a ceramic insulator is high-temperature bonded between a wraparound lead layer and a buffer layer of a same material as the lead layer to provide a symmetrically balanced three-layer structure. In a second step, the three-layer structure is high temperature bonded, using a lower melt point braze, to a heat spreader. This package configuration minimizes package deflection, and thereby improves thermal dissipation and reliability of the package.Type: GrantFiled: June 22, 2018Date of Patent: September 10, 2019Assignee: Kyocera International, Inc.Inventors: Franklin Kim, Mark Eblen, Shinichi Hira

Publication number: 20190006254Abstract: A semiconductor packaging structure is disclosed. The semiconductor packaging structure includes a heat spreader, a set of at least two leads, and a ceramic insulator. The heat spreader has a thermal conductivity greater than 300 W/m*K. The ceramic insulator has a mean flexural strength that is greater than 500 MPa and so better able to withstand the thermal expansion mismatch between it and the heat spreader. The heat spreader, the set of at least two leads, and the ceramic insulator may also be part of a semiconductor package along with at least one semiconductor device, a wire bond, and a ceramic lid.Type: ApplicationFiled: June 28, 2018Publication date: January 3, 2019Inventors: Mark EBLEN, Franklin KIM, Paul GARLAND, Shinichi HIRA

Patent number: 9647479Abstract: A charging control device includes a control unit and a monitoring unit. The control unit performs at least one of controlling charging to a rechargeable battery and monitoring a state of a rechargeable battery, while outputting a state signal which indicates an operation state of the control unit. The monitoring unit determines whether or not the operation state of the control unit is a predesignated specified operation state based on the state signal outputted from the control unit.Type: GrantFiled: October 21, 2014Date of Patent: May 9, 2017Assignee: MAKITA CORPORATIONInventors: Tatsuki Mori, Toru Yamada, Shinichi Hira, Hitoshi Suzuki

Patent number: 9224994Abstract: An adapter for an electric power tool couples battery packs with the electric power tool. The adapter is provided with a voltage regulator circuit interposed between the battery packs and the electric power tool. The voltage regulator circuit regulates a supply voltage from the battery packs to the electric power tool to a level corresponding to a rated voltage of the electric power tool. The voltage regulator is capable of raising the supply voltage higher than nominal voltages of the battery packs.Type: GrantFiled: March 15, 2011Date of Patent: December 29, 2015Assignee: MAKITA CORPORATIONInventors: Tomoyuki Ota, Shinichi Hira, Tadashi Makihara
