Patent number: 6515266Abstract: A cooking apparatus has a door for opening and closing the opening of a heating chamber. The door has an operation portion that permits setting of heating conditions such as heating time and heating mode and a display panel for displaying the heating conditions. The door is composed of a door frame constituting the outer frame of the door, and a door screen made of an elastic material and fitted in the door frame. A door sheet is laid over the door screen by being bonded thereto. In the door sheet are formed operation keys that are arranged in the operation portion, a transparent portion that serves as a display window through which to view the display panel, and a transparent portion that serves as a peep window through which to look into the heating chamber.Type: GrantFiled: January 24, 2001Date of Patent: February 4, 2003Assignee: Sharp Kabushiki KaishaInventors: Tadashi Nasu, Tadanobu Kimura

Patent number: 5065552Abstract: An active seismic response control system includes a variable damping device provided between posts, beams and braces of a structure, wherein the response of the frame is reduced by controlling the variable damping device when an earthquake or strong wind occurs to give a damping force to the frame. The response of the structure is determined by the steps of judging with a computer the optimal damping force or control force to be applied to the structure on the basis of information obtained from sensors in response to the disturbance, and then controlling the coefficient of damping of the variable damping device.Type: GrantFiled: February 5, 1990Date of Patent: November 19, 1991Assignee: Kajima CorporationInventors: Takuji Kobori, Motoichi Takahashi, Tadashi Nasu, Naoki Niwa, Narito Kurata, Junichi Hirai, Yoshinori Adachi

Patent number: 5036633Abstract: A variable damping and stiffness structure is disclosed, which includes a variable damping device provided between posts, beams and braces of a structure or braces serving as variable stiffness elements and interconnecting a frame body and the variable stiffness element or the variable stiffness elements themselves. Not only the unreasonance property, but also the damping property of the structure are compositely judged by a computer on the basis of information obtained from sensors with respect to disturbances such as earthquake and wind to control the connecting condition of the variable damping device, whereby both the unresonance property and the damping property are controlled to reduce the response amount of the structure. Otherwise, the variable damping device is controlled by the judgement of only the damping property.Type: GrantFiled: February 6, 1990Date of Patent: August 6, 1991Assignee: Kajima CorporationInventors: Takuji Kobori, Motoichi Takahashi, Tadashi Nasu, Naoki Niwa, Narito Kurata, Junichi Hirai, Yoshinori Adachi, Koji Ishii
