Patent number: 5642294Abstract: A buffer memory buffers a sequence of image data I.sub.0, I.sub.1, . . . of respective frames while shifting them step by step and discarding the least recent one of them for each step. An inter-image distance calculating means calculates the distance d(t-i, t-j) between respective pieces of image data held in the buffer memory and stores such distance values in a distance table part in a sequential order. A scene changing ratio calculating part calculates the scene changing ratio C(t-j.sub.c) at time t while referring to the distance table part. A decision part compares the scene changing ratio C(t-j.sub.c) with a predetermined threshold value to determine if the image of a preceding frame j.sub.c -th from the time t is a cut point.Type: GrantFiled: December 15, 1994Date of Patent: June 24, 1997Assignee: Nippon Telegraph and Telephone CorporationInventors: Yukinobu Taniguchi, Yoshinobu Tonomura

Patent number: 4315472Abstract: When a pulse motor in an electronic sewing machine is to be subjected to a heavy load, the pulse motor is operated at a slower speed in order to cause the pulse motor to operate at a rate in which it has a maximum torque output. For lesser load conditions, pulse motor speed is allowed to increase. Speed control of the pulse motor follows a generally trapezoidal curve, which curve includes a speed-up section and a slow-down section, and may include a flat section. That portion of the generally trapezoidal curve along which motor speed follows is determined by the distance which the pulse motor is required to move.Type: GrantFiled: March 18, 1980Date of Patent: February 16, 1982Assignee: Janome Sewing Machine Co.

Patent number: 4290375Abstract: An automatic embroidery machine is driven by information recorded on magnetic tape and utilizes a fixed sewing machine and a movable embroidery frame. An input apparatus registers user-selected points on a coordinate analysis panel, which points form embroidery patterns to be sewn, and causes embroidery information to be recorded upon magnetic tape for subsequent use in the automatic embroidery machine. The automatic embroidery machine and the input apparatus are so designed that after a continuous part of an embroidery pattern has been sewn, the embroidery frame will be moved to a next continuous part of a pattern and the automatic embroidering machine will stop, providing an opportunity for a user to change thread. The automatic embroidering machine cannot be restarted unless the user operates a controller, ensuring safe operation.Type: GrantFiled: October 3, 1979Date of Patent: September 22, 1981Assignee: Janome Sewing Machine Co., Ltd.Inventors: Yoshinobu Tonomura, Toshio Fujimura, Masanori Hara, Hideaki Takenoya

Patent number: 4289087Abstract: The tension of the sewing machine's upper thread is varied automatically, in a variety of ways not requiring conscious participation on the part of the user of the machine. When one of a set of selectable stitch-patterns is selected by the user, an appropriate thread-tension value is automatically established, although the user retains the ability to adjust the automatically established tension value if he wishes. When the user swings the presser-foot lever of the machine up, to raise the cloth presser foot up from the cloth, e.g., for basting work, the thread tension is automatically lowered to a predetermined value suitable for basting, although still adjustable by the user if he thinks necessary. Where a stitch-pattern is implemented using an addressable ROM, tension command data for each stitch of the stitch-pattern may be stored in the ROM, for variation of thread tension from constituent stitch of the pattern to the next.Type: GrantFiled: September 28, 1979Date of Patent: September 15, 1981Assignee: Janome Sewing Machine Co., Ltd.Inventors: Hideaki Takenoya, Kazuo Watanabe, Tamotsu Nakagawa, Yoshinobu Tonomura
