Patent number: 12267673Abstract: A terminal device may be configured to receive support information from a communication device by using a first wireless connection which has been established between the terminal device and the communication device. The support information may indicate whether the communication device supports a predetermined scheme. The terminal device may be configured to, in a case where the support information indicates that the communication device supports the predetermined scheme, execute a first control process for executing wireless communication in conformity with the predetermined scheme between the terminal device and the communication device. The terminal device may be configured to, in a case where the support information indicates that the communication device does not support the predetermined scheme, execute a second control process for executing wireless communication in conformity with a different scheme different from the predetermined scheme between the terminal device and the communication device.Type: GrantFiled: April 27, 2022Date of Patent: April 1, 2025Assignee: Brother Kogyo Kabushiki KaishaInventors: Takeshi Shibata, Hirotaka Asakura

Patent number: 6889795Abstract: An electric power steering device in which a motor shaft and a rack bar form a diagonal intersection. The power transmission includes: a drive gear rotating in tandem with the motor shaft and forming a bevel gear with linearly extending teeth; a ball screw mechanism disposed co-axial with the rack bar and converting a rotational motion to a linear motion; and a driven gear rotating in tandem with a nut of the ball screw mechanism, meshing with and moving in tandem with the drive gear, and forming a bevel gear with linearly extending teeth. The drive gear and/or the driven gear can be adjusted so that backlash between the two elements can be adjusted in a continuous, non-stepped manner.Type: GrantFiled: September 24, 2003Date of Patent: May 10, 2005Assignee: Toyoda Koki Kabushiki KaishaInventors: Hirotaka Shibata, Mikio Suzuki, Osamu Watanabe, Masanari Torii, Susumu Honaga

Patent number: 5702993Abstract: A triaxial fabric composed of carbon fiber strands is provided, which has a crimp releasing ratio (L'-L)/L satisfying ?(L.sub.0 -L)/L.sub.0 !.times.0.7.gtoreq.(L'-L)/L.gtoreq.0. Since the crimps of the fiber strands composing the fabric are preliminarily fixed, fiber breakage due to abrasion in the intersecting portions of the fabric is prevented, whereby a high quality triaxial fabric is obtained. A method for the production of such a fabric is also provided.Type: GrantFiled: July 3, 1996Date of Patent: December 30, 1997Assignees: Nippon Steel Corporation, Sakase Adteck Co.Inventors: Kenji Kubomura, Hiromi Kimura, Hirotaka Shibata

Patent number: 4898137Abstract: Several embodiments of vehicles having automatic or manual speed control. The manual speed control permits the operator to control the speed of the engine and the automatic speed control is effective when a power takeoff shaft is being driven for automatic speed control under this condition. In each embodiment, the automatic speed control includes a governor that is driven only when the power shaft takeoff is being driven. In one embodiment, a throttle valve controls the engine speed and the manual and automatic speed controls alternatively operate the throttle valve through selectively engageable couplings that are operated in response to shifting into and out of the power takeoff mode. A number of other arrangements are also illustrated and described that provide different throttle valve arrangements for controlling the speed automatically or manually.Type: GrantFiled: January 13, 1989Date of Patent: February 6, 1990Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Minoru Fujita, Hirotaka Shibata

Patent number: 4744432Abstract: Several embodiments of balloon tired, off the road vehicles embodying improved cooling systems. In each embodiment, the engine is surrounded by a cooling shroud and a fan is provided for driving air across the engine. The fan is offset from the engine crankshaft axis and is driven by it. In some embodiments, foreign matter is precluded from entry into the shroud inlet by positioning the inlet in a protected area such as over the fender, under the body, under the fuel tank, or under the seat.Type: GrantFiled: January 22, 1986Date of Patent: May 17, 1988Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Hirotaka Shibata, Masahiro Nishioka

Patent number: 4593656Abstract: Several embodiments of induction systems for motor vehicles that improve running at low speeds. A plenum chamber is provided which communicates with the intake passage downstream of the throttle valve so as to improve flow dynamics particularly at these running conditions. The plenum chamber is supported by the vehicle chassis independently of the engine and communicates with the induction passage via a flexible conduit.Type: GrantFiled: June 28, 1985Date of Patent: June 10, 1986Assignee: Yamaha Hatsukoki Kabushiki KaishaInventors: Hirotaka Shibata, Takayoshi Muramatsu
