Patent number: 11964356Abstract: A hand-held tool, such as a disc grinder, is used to perform work at a high work site, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool, such as a tether strap. If a coupling part that couples the suspension tool to the hand-held tool is damaged, this fact is notified to a user. Thereby, an original function of the suspension tool can be reliably performed. If a large impact is applied to a coupling member via a suspension tool, the coupling member is displaced to a second position, due to the deformation of a first position retaining member. A conductive portion disengages from contacts to cause a power circuit to be shut off, thereby prohibiting a main body part from being activated.Type: GrantFiled: March 27, 2019Date of Patent: April 23, 2024Assignee: MAKITA CORPORATIONInventors: Ryosuke Otani, Junya Ishikawa, Takafumi Kotsuji, Satoshi Ninagawa, Ken Goto, Yu Eto

Publication number: 20240092424Abstract: An electromotive compressor fixed to a front side of an engine includes a live part. A harness connection portion where a hinge-voltage harness is connected is provided in an outer peripheral area of a left side, in a vehicle width direction, of the electromotive compressor. A protecting member comprises a first cover portion which covers an area corresponding to the live part from the front side and a second cover portion which is provided continuously to the first cover portion and covers the harness connection portion from the front side with a specified distance from the harness connection portion. A low rigidity portion which has lower rigidity than the first covet portion and the second cover portion is provided at a continuous portion of the first cover portion and the second cover portion.Type: ApplicationFiled: February 14, 2023Publication date: March 21, 2024Applicant: MAZDA MOTOR CORPORATIONInventors: Yuki WATABE, Yasushi ISHIKAWA, Ryosuke UETA, Shinji YAMAUCHI

Patent number: 9834014Abstract: The disclosure discloses a printer including a printing head, a DC motor, an energization control part, a short-circuiting device, a temperature detecting device, and a braking control part. The DC motor is configured to generate a driving force for feed by a feeder. The energization control part is configured to control energization by an energizing device. The short-circuiting device is configured to short-circuit a positive electrode and an negative electrode of the DC motor and brake when deenergized under control of the energization control part. The temperature detecting device is configured to detect a temperature of ambient surroundings. The braking control part is configured to control the short-circuiting device in accordance with the temperature detected by the temperature detecting device, to thereby variably control an operation mode of the braking by the short circuiting.Type: GrantFiled: January 12, 2017Date of Patent: December 5, 2017Assignee: Brother Kogyo Kabushiki KaishaInventors: Ryosuke Ishikawa, Yasuhiko Murakami, Yushi Kato

Patent number: 8736895Abstract: A tape printing apparatus compares a back-side background region of print data to be previously printed and a front-side background region of print data to be subsequently printed upon receipt of plural print data including background. If they are different, the tape printing apparatus creates a front-side color mixture tolerance region and a back-side color mixture tolerance region based on the front-side background region and the back-side background region, respectively, so that the front-side color mixture tolerance region and the back-side color mixture tolerance region are arranged continuously. The apparatus sets cut positions at a front edge border and a back edge border of each print data and cut the tape off at those portions while carrying out full-color print on the tape based on respective print data.Type: GrantFiled: September 26, 2012Date of Patent: May 27, 2014Assignee: Brother Kogyo Kabushiki KaishaInventors: Kishiro Yamaguchi, Tsutomu Kato, Susumu Murata, Ryosuke Ishikawa
