Patent number: 6145278Abstract: A tape packing method capable of packing a tape in such a mode that it can be let off with neither twist nor entanglement from its packing box. When the tape 1 is to be boxed and packed by dropping it, a turning force around the center portion of a packing box 4 is applied to the tape 1 being dropped into the packing box 4, and the direction of the turning force to be applied is alternately switched forward and backward at each predetermined number of turns.Type: GrantFiled: December 17, 1998Date of Patent: November 14, 2000Assignee: Idemitsu Petrochemical Co., Ltd.Inventor: Kazuyoshi Tanaka

Patent number: 5703659Abstract: A method is provided for reducing or magnifying the picture size of a video composite signal with the use of fewer memories than a conventional video composite signal processor which processes pixel data after being converted into R, G, B signals. A video composite signal is directly converted into digital data and sampled with a sampling frequency of four times the color sub-carrier and stored in a pair of field buffers to be processed for picture size reduction or magnification. The digital data are reduced or multiplied in units of pairs of data with a phase difference of .pi./2. Color information is reproduced from corresponding two pairs of data of two adjacent fields having a phase difference of .pi..Type: GrantFiled: March 19, 1996Date of Patent: December 30, 1997Assignee: NEC CorporationInventor: Kazuyoshi Tanaka

Patent number: 5558340Abstract: A game machine includes a housing; a grip mechanism including two hands for gripping articles mounted on a rear wall of the housing; a drive mechanism for moving the grip mechanism vertically and/or horizontally, and depthwise in the housing; a control mechanism for controlling starting and stopping of the drive mechanism; and an input mechanism manually controlled by a game user for sending signals to the control mechanism to start and stop vertical and/or horizontal movement of the grip mechanism. Depthwise movement of the grip mechanism is actuated by the control mechanism after horizontal and vertical movement is stopped. A sensor mechanism on the grip mechanism senses the presence of a prize between the two hands and sends a signal to the control mechanism to close the hands to grip the article whereupon the grip mechanism is returned to a home position, the hands are released and the prize is delivered to the user.Type: GrantFiled: August 11, 1995Date of Patent: September 24, 1996Assignee: Kabushiki Kaisha BanprestoInventors: Takaya Ibe, Kazuyoshi Tanaka, Kaname Ota, Goujun Yamamoto, Toshihiro Okabe

Patent number: 5524257Abstract: The same data is processed in parallel by a plurality of different algorithms for deriving the same processing result from the same data. When an algorithm derives a processing result first, the processing result is used and the processing by the other algorithms is stopped or interrupted and updated to the same data which is reflected by the processing result data. This updated data is processed in parallel once again by a plurality of different algorithms, and when an algorithm derives another processing result first, the processing result is used, and the above processing is repeated, and inference. Consequently, sorting, data compression, simulation, and neurolearning can be processed at the highest possible speed.Type: GrantFiled: January 19, 1993Date of Patent: June 4, 1996Assignees: Hitachi, Ltd., Hitachi Seibu Software, Ltd.Inventors: Hiroshi Koike, Kazuyoshi Tanaka

Patent number: 5479534Abstract: A technique for estimating an unsampled color data on the basis of plural color data sampled by a line image sensor. The sensor includes at least two types of color filters such as a red filter and a green filter. Those filters are alternately arranged pixel by pixel in a line of pixels so that A-type color data which corresponds to green data is sampled from a target pixel and plural B-type color data which correspond to red data are sampled from neighbor pixels neighboring the target pixel. An unsampled B-type color data of the target pixel is estimated by synthesizing the sampled A-type color data of the target pixel and the sampled B-type color data of the neighbor pixels.Type: GrantFiled: February 22, 1995Date of Patent: December 26, 1995Assignee: Konica CorporationInventors: Kazuyoshi Tanaka, Masahiro Yamaguchi, Nagaaki Oyama, Toshio Honda
