Patent number: 11950732Abstract: A toilet device includes an electric opening/closing unit including a motor and a transmission mechanism. The transmission mechanism includes an internal gear, a first transmission part and a second transmission part. The first transmission part transmits a rotational force of the motor. The second transmission part transmits a rotational force of the first transmission part. The first transmission part includes a first planetary gear and a first planetary carrier. The second transmission part includes a second planetary gear, a second planetary carrier, and a shaft part. The shaft part revolves around a rotation axis. The first planetary carrier includes a protrusion extends along a trajectory of the revolution of the shaft part. The shaft part contacts the protrusion. A gap is formed between the shaft part and a part of the first planetary carrier other than the protrusion.Type: GrantFiled: September 13, 2022Date of Patent: April 9, 2024Assignees: TOTO LTD., DAIICHI KASEI CO., LTD., YOKO INDUSTRY CO., LTD.Inventors: Hiroki Hata, Yuji Maruyama, Maya Teraoka, Haruki Suzuki, Toshihiko Shimizu

Patent number: 11805949Abstract: A toilet device includes an electric opening/closing unit configured to open and close at least one of a toilet seat or a toilet lid. The electric opening/closing unit includes a case, a motor, an output shaft, a transmission mechanism and a spring. The output shaft outputs a rotation of the motor to one of the toilet seat or the toilet lid. The transmission mechanism transmits the rotation of the motor to the output shaft. The spring is connected to the transmission mechanism and the output shaft. The spring urges the output shaft in a rotational direction of the output shaft. The transmission mechanism includes an engaging part engaging the spring. The engaging part engages an end part of the spring at the transmission mechanism side and restricts the end part from moving in a circumferential direction of the spring and from moving in a radial direction of the spring.Type: GrantFiled: September 13, 2022Date of Patent: November 7, 2023Assignees: TOTO LTD., DAIICHI KASEI CO., LTD., YOKO INDUSTRY CO., LTD.Inventors: Hiroki Hata, Yuji Maruyama, Maya Teraoka, Haruki Suzuki, Toshihiko Shimizu

Patent number: 6550136Abstract: The present invention aims to provide a method of fabricating a printed wiring board characterized in that a printed wiring board is fabricated by perforating a slot by a router bit at a central part of a substrate. The method further includes cutting a wiring portion for electric plating by the router bit. According to the method, the occurrence of cut burr on the surfaces of the wiring pattern, caused by electric plating, is prevented, the product yield is promoted and the operational efficiency is improved. The invention also discloses a method of fabricating a printed wiring board by forming a conductor circuit by patterning a metal coating formed on a surface of an insulating substrate, successively subjecting the conductor circuit to a surface treatment by electric plating and thereafter perforating a slot by a router bit. The slot connects the substrate to a semiconductor chip at a central portion thereof by bonding wires.Type: GrantFiled: February 23, 2000Date of Patent: April 22, 2003Assignee: Sumitomo Metal Mining Co., LTDInventors: Hiroki Hata, Kenichi Yamane, Akihiro Nishimura, Noriaki Taneko
