Patent number: 12000611Abstract: In an air conditioner of the present embodiment capable of selecting either a fan rotation speed determined on the basis of a static pressure value and an air volume or a required fan rotation speed, motor control means determines, on the basis of the static pressure Pt, the fan rotation speed Rm of a fan motor that provides the air volume Av required by the user, and transmits the determined fan rotation speed Rm to an indoor unit control means. When the fan rotation speed Rm received from the motor control means is a prohibited rotation speed, the indoor unit control means transmits a correction fan rotation speed different from the prohibited rotation speed to the motor control means, and the motor control means drives the fan motor at the received correction fan rotation speed.Type: GrantFiled: September 18, 2020Date of Patent: June 4, 2024Assignee: FUJITSU GENERAL LIMITEDInventors: Yutaka Shimamura, Takashi Matsuzaki, Toshihiko Watanabe

Patent number: 9856168Abstract: Turning motion of gypsum slurry spouting onto a sheet of paper for a gypsum board liner is restricted for preventing maldistribution, deviation or irregular dispersion from occurring in the density distribution of the slurry on the sheet of paper. A mixing and stirring device for gypsum slurry has a circular casing forming a mixing area, a rotary disc positioned in the casing, and a tubular passage for feeding the slurry onto the sheet of paper for the gypsum board liner. A chute has a fluid passage portion with its cross section being non-axisymmetric with respect to a center axis of the tubular passage, or a fluid passage portion varying a position of the center axis of the tubular passage by a change or lateralization of the cross section of fluid passage.Type: GrantFiled: November 27, 2013Date of Patent: January 2, 2018Assignee: YOSHINO GYPSUM CO., LTD.Inventors: Yasutoshi Ueno, Hitoshi Inenaga, Yutaka Matsuzaki

Patent number: 6072120Abstract: A top phase transmission line and bottom phase transmission line are stretched between support steel towers so that the bottom phase transmission line is positioned below the top phase transmission line. Each of the transmission lines has at least two conductors, which conductors are arranged to be substantially parallel and are separated by a substantially constant distance by interconductor spacers. An intermediate phase transmission line may be arranged between the top phase transmission line and bottom phase transmission line as well. Such transmission lines are multiconductor transmission lines. In these multiconductor transmission lines, the conductor positioned at the left side in the top phase transmission line and the conductor positioned at the right side in the intermediate phase transmission line or bottom phase transmission line directly below it are connected by a first interphase spacer made of an insulator.Type: GrantFiled: February 27, 1997Date of Patent: June 6, 2000Assignee: The Furukawa Electric Co., Ltd.Inventors: Yutaka Matsuzaki, Jun Katoh, Takeo Munakata

Patent number: 4634945Abstract: An apparatus for automatically opening and closing a closure panel associated with an opening formed in the roof of an automobile is disclosed. The apparatus drives the closure panel for tilt open and tilt closed operation and for slide open and slide closed operation. During the sliding movement of the panel, the apparatus detects a load on a panel drive mechanism in a zone where the loads are normally low, and deenergizes the panel drive mechanism in the event of occurrence of an overload. In a zone where the loads are normally high as the panel presses against a weather strip, no deenergization of the panel drive mechanism occurs during an interval allocated for overload detection. The apparatus energizes alarm means during the time the panel is driven in the closing direction in a selected mode in order to draw the attention of a vehicle driver. For assuring the safeguard of the panel, the panel is stopped temporarily during the slide closed operation at a point which leaves a given opening.Type: GrantFiled: November 28, 1984Date of Patent: January 6, 1987Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Shinji Takemura, Tsuneo Hida, Yutaka Matsuzaki, Kenichi Ohnishi

Patent number: 4597587Abstract: A seatbelt system includes a webbing which has one end thereof attached to a door of a vehicle and is automatically fastened to an occupant of the vehicle in response to the action of opening and closing the door. The webbing tension is decreased when the door is opened, whereby it is possible to reduce the resistance due to the webbing tension encountered when the door is opened. Further, when the door is closed, the webbing tension is increased, thereby bringing the webbing into close contact with the occupant.Type: GrantFiled: November 27, 1984Date of Patent: July 1, 1986Assignee: Toyota Jidosha Kabushiki KaishaInventors: Noritada Yoshitsugu, Motonobu Sugiura, Yutaka Matsuzaki

Patent number: 4585251Abstract: A seatbelt system automatically fastens a webbing to an occupant of a vehicle after he has entered the vehicle and seated in a seat. The wind-up force of a webbing retractor for winding up the webbing is temporarily reduced by a control means in the course of the operation for fastening the webbing to the occupant. Thus, it is possible to eliminate the possibility that the webbing may rub against the body of the occupant during the operation for automatically fastening the webbing to the occupant.Type: GrantFiled: October 26, 1984Date of Patent: April 29, 1986Assignee: Toyota Jidosha Kabushiki KaishaInventors: Noritada Yoshitsugu, Masakazu Hashimoto, Yutaka Matsuzaki

Patent number: 4580812Abstract: In a seatbelt system in which an occupant restraining webbing, one end thereof being secured to a door of a vehicle, is moved in directions of a front and a rear of the vehicle in accordance with an opening and a closing of the door and an occupant is automatically fastened by the webbing, when a motor of a webbing retractor is driven in response to a signal from a switch detecting an opened degree of the door, so that a tension of the webbing is reduced.Type: GrantFiled: August 1, 1984Date of Patent: April 8, 1986Assignee: Toyota Jidosha Kabushiki KaishaInventors: Noritada Yoshitsugu, Motonobu Sugiura, Yutaka Matsuzaki

Patent number: 4555250Abstract: A glass-grinding sheet is prepared by a process wherein 100 wt. parts of a powdery metal composition consisting of, based on the weight of the composition, 80-96.8% copper, 3-15% of tin and/or zinc, and 0.2-5% of nickel and/or titanium, are mixed with 0.5-30 wt. parts of a diamond powder; the mixture is sintered; and then, the obtained sintered body is rolled into a sheet of the desired thickness. The powdery metal composition is either a copper alloy consisting of (a) copper, (b) tin and/or zinc and (c) nickel and/or titanium, or a mixture of a copper alloy consisting of (a) copper and (b) tin and/or zinc, with (c) nickel and/or titanium.Type: GrantFiled: May 29, 1984Date of Patent: November 26, 1985Assignee: Showa Denko Kabushiki KaishaInventors: Shin'ichi Horie, Yutaka Matsuzaki, Fumio Kagawa
