Patent number: 11939267Abstract: A method and apparatus for producing AlN whiskers includes reduced incorporation of metal particles, an AlN whisker body, AlN whiskers, a resin molded body, and a method for producing the resin molded body. The method for producing AlN whiskers includes heating an Al-containing material in a material accommodation unit to thereby generate Al gas; and introducing the Al gas into a reaction chamber through a communication portion while introducing nitrogen gas into the reaction chamber through a gas inlet port, to thereby grow AlN whiskers on the surface of an Al2O3 substrate placed in the reaction chamber.Type: GrantFiled: May 2, 2022Date of Patent: March 26, 2024Assignee: NATIONAL UNIVERSITY CORPORATION NAGOYA UNIVERSITYInventors: Toru Ujihara, Yukihisa Takeuchi, Daishi Shiojiri, Masaki Matsumoto, Hiroshi Saito, Ikuo Hayashi

Patent number: 6968592Abstract: A self-running vacuum cleaner comprises a homing mode of following a back of a user with receiving a signal from a light emitting means or a transmitting means of a position indicator means held by the user, an instruction operation mode, in which the user instructs a cleaning area to the self-running vacuum cleaner, and an execution mode for cleaning up the cleaning area instructed. When the self-running vacuum cleaner operates under the homing mode or the instruction mode, a signal from the light-emitting means or the transmitting means is received by a receiver means attached on a periphery portion of a measuring means, which is provided in an upper portion of the vacuum cleaner. Comparing the signals from the two (2) receiver means in strength thereof determines the distance and the direction from the position indicated by the light-emitting means or the transmitting means up to the vacuum cleaner.Type: GrantFiled: March 22, 2002Date of Patent: November 29, 2005Assignee: Hitachi, Ltd.Inventors: Ikuo Takeuchi, Yutaka Arai, Yasuhiro Nemoto, Atsushi Koseki, Taiji Tajima

Patent number: 6704523Abstract: The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.Type: GrantFiled: July 25, 2002Date of Patent: March 9, 2004Assignee: Canon Kabushiki KaishaInventors: Ikuo Takeuchi, Kunio Tsuruno, Tetsuya Morita, Keizo Isemura, Ichiro Sasaki, Masahiro Kurahashi, Atsushi Nakagawa, Kenji Fukushi
