Patent number: 7224350Abstract: An image display device well suited for a multi-scanning type monitor includes a video signal measurement circuit that detects a horizontal synchronization frequency fH and a vertical synchronization frequency fV from an input image signal that conforms to the GTF Standard. A main control portion calculates timing data relative to a waveform of the signal (21) using the frequencies fH and fV, calculates adjustment parameters for adjusting a size and a position using this timing data, and sets the adjustment parameters to deflection control circuits, so that an image of the image signal may be displayed well on a CRT. Since the timing data is calculated using the synchronization frequencies fH and fV of the input image signal, it is possible to save on a memory capacity without storing timing data that corresponds to a plurality of different kinds of image signals.Type: GrantFiled: June 27, 2002Date of Patent: May 29, 2007Assignee: Sony CorporationInventors: Shigeru Takasu, Motosuke Irie

Publication number: 20070064783Abstract: An in-home-system master station of an in-home communication system detects a frequency band (a channel number corresponding to a data communication subchannel) or a time slot used by each station of an access communication system, using a coexistence signal subchannel. Based on the detected information, the in-home-system master station determines a frequency band or a time slot to be used in the in-home communication system to which the in-home-system master station belongs, so as not to avoid overlapping the frequency or time slot used in the access communication system, and informs each in-home-system slave station of the determined frequency band or time slot.Type: ApplicationFiled: July 5, 2006Publication date: March 22, 2007Inventors: Go Kuroda, Akio Kurobe, Koji Ikeda, Hisao Koga, Yuji Igata, Hirotoshi Yamada, Yoshinori Mizugai, Hiromu Okamoto, Junichi Ohshima, Shigeru Takasu, Takehiro Sugita

Patent number: 6366263Abstract: The size of an image displayed on a tube surface is varied while maintaining the aspect ratio thereof at a constant. First, if there is information of an arbitrary horizontal-size variable parameter and a vertical-size variable parameter because of parameters supplied previously by adjustments, the horizontal/vertical size of a raster formed at that time can be obtained, and the aspect ratio thereof can be obtained on the basis of the horizontal/vertical size of the raster. Then, during a zoom mode, the vertical-size variable parameter corresponding to the updated horizontal-size variable parameter is computed so that the detected aspect ratio becomes constant, and the raster size is changed in accordance with these values.Type: GrantFiled: March 4, 1998Date of Patent: April 2, 2002Assignee: Sony CorporationInventors: Shigeru Takasu, Toshinori Hamada, Motosuke Irie, Satoru Suzuki

Patent number: 4513481Abstract: A bottom tenser utilized for a drafting means of a spinning frame, especially for fasciated yarn spinning, in which a fiber bundle is attenuated at a high speed exceeding 100 m/min. The bottom tenser as well as a bottom roller corresponding to the tenser is provided with a free end through which an apron is easily removable from and mountable on the tenser and the roller. The tenser may be constituted by a body and at least a guide wall movable relative to the body. The guide wall prevents lateral movement of the apron in its operative position and, in turn, is displaced or removed from the body in its non-operative position so as not to obstruct an apron exchanging operation.Type: GrantFiled: August 17, 1983Date of Patent: April 30, 1985Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Yoshihisa Suzuki, Yoshiharu Yasui, Kazuo Seiki, Shigeru Takasu

Patent number: 4498216Abstract: A textile fiber drafting apparatus is disclosed, according to which the drafting bottom rollers in each line along the spinning units of a spinning frame are arranged in such a way that each two adjacently juxtaposed bottom rollers make a single block for each two spinning units, so that each bottom roller has an open, free end through which an apron may be replaced with a new one or fibers entangled on the roller may be removed with extreme ease. Between each such two spinning units is provided an arrangement for driving the bottom rollers thus disposed, including driving and driven mechanisms.Type: GrantFiled: May 27, 1983Date of Patent: February 12, 1985Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Yoshihisa Suzuki, Yoshiharu Yasui, Shigeru Takasu

Patent number: 4480435Abstract: A false-twist nozzle with an improved structure is provided herein. The false-twist nozzle according to the invention comprises a housing having a large-diameter yarn passage portion and an insert member having a small-diameter yarn passage portion and a fluid conduit hole. When the insert member is within the housing, a complete yarn passage hole is formed through the nozzle. Because the insert member is separable from the housing, drilling of the very small diameter fluid conduit hole can be made easily and accurately prior to insertion within the housing. Furthermore, the fluid conduit opening is disposed both annularly and angularly in the downstream direction with respect to the yarn passage hole, thereby increasing the twisting action induced by the flow of jetted fluid while preventing damage to the yarn.Type: GrantFiled: December 23, 1982Date of Patent: November 6, 1984Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Meiji Anahara, Yoshihisa Suzuki, Shigeru Takasu, Hiroshi Omori
