Patent number: 8230381Abstract: With a conventional method for designing cell layout, it is necessary to give relative positional information in advance to all cells to be arranged. Furthermore, the conventional method is troublesome because it is necessary to correct relative positional information of cells after confirming a result of temporary layout. Therefore, it takes time to obtain a layout result. To avoid these problems, cells of a specific type specified from outside, or cells satisfying specific conditions, are extracted and arranged first or limited to a layout position by specifying a layout position, then arranging the remaining cells using a general layout algorithm.Type: GrantFiled: May 4, 2010Date of Patent: July 24, 2012Assignee: Hitachi, Ltd.Inventors: Katsuyuki Itoh, Hironori Iwamoto

Method for designing cell layout of a semiconductor integrated circuit with logic having a data flow
Patent number: 7735040Abstract: With a conventional method for designing cell layout, it is necessary to give relative positional information in advance to all cells to be arranged. Furthermore, the method is troublesome because it is necessary to correct relative positional information of cells after confirming a result of temporary layout. Therefore, it takes time to obtain a layout result. The present invention extracts cells of a specific type specified from outside or cells satisfying specific conditions, arranges these specific cells first or limits a layout position by specifying a layout position, then arranges the remaining cells using a general layout algorithm.Type: GrantFiled: January 19, 2007Date of Patent: June 8, 2010Assignee: Hitachi, Ltd.Inventors: Katsuyuki Itoh, Hironori Iwamoto -

Patent number: 6190339Abstract: A massage device has first and second massage members. The first massage member performs a circulating motion including (i) a massage zone where the member approaches the second massage member in a locus which swells in an outward direction as seen from a massage arm; and (ii) a release zone where the member separates from the second massage member in a locus which is shorter than the massage zone. The second massage member performs a reciprocal rocking motion in synchronization with the first massage member.Type: GrantFiled: August 26, 1997Date of Patent: February 20, 2001Assignee: Matsushita Electric Works, Ltd.Inventors: Mikiharu Imazaike, Hironori Iwamoto, Keiji Hata, Yoshiyuki Miyake, Yoshikazu Okada

Patent number: 5997489Abstract: A massager comprises a handle, a roller rotatably supported at one end of the handle and having a peripheral surface adopted to contact a human body, and a vibration generating unit for giving a vibration to the roller. A head for incorporating the vibration generating unit therein is formed at the end of the handle. The roller is disposed on an outer surface of the head to which the vibration is applied. The present massager can selectively provide a vibration massage of applying a vibration to a skin through the roller rolled along the skin, and a vibration massage of applying a vibration to a skin through a peripheral portion of the head pressed against the skin. As a result, it is possible to provide an adequate vibration massage in accordance with the circumstances.Type: GrantFiled: April 9, 1997Date of Patent: December 7, 1999Assignee: Matsushita Electric Works, Ltd.Inventors: Hironori Iwamoto, Sanai Fukui, Haruhiko Naruse, Keiji Hata, Maki Hirakawa, Mikio Ito

Patent number: 5827205Abstract: A foot massager having massaging applicators and capable of holding the feet of a user stably thereon to avoid an accidental actuation of a control section by the feet. A massager housing has an inclined top wall. The applicators are supported to the inclined top wall and are movable in a massage direction perpendicular to a general outer surface of the inclined top wall. Mounted within the housing are a pair of solenoids each having a plunger of which longitudinal axis is aligned with the massage direction. The plunger is connected at its upper end with the applicator and is attracted by repetitive energization of the solenoid to periodically move the applicator upward along the massage direction from a depressed position where the applicator is depressed by the foot of the user, thereby giving a tapping massage action to the foot. The control section is provided on a lower portion of the top wall adjacent to a front lower end of the housing and includes a switch for actuating the solenoid.Type: GrantFiled: September 12, 1996Date of Patent: October 27, 1998Assignee: Matsushita Electric Works, Ltd.Inventor: Hironori Iwamoto

Patent number: 5193528Abstract: A hand-held extensible vibratory massager comprises a hand grip to be grasped by a hand of a user, a self-contained vibration applicator generating a vibratory massaging motion. An arcuately extensible arm interconnects the hand grip and the applicator so that the applicator is movable along an arcuate path from a normal position adjacent the hand grip to an extended position away therefrom, facilitating to locate the applicator on a portion of the body over an extended range with enhanced operability.Type: GrantFiled: January 7, 1991Date of Patent: March 16, 1993Assignee: Matsushita Electric Works, Ltd.Inventors: Hironori Iwamoto, Kuniharu Ichikawa, Taro Mochida, Teruhisa Innami

Patent number: 4958628Abstract: A hand-held vibratory massager has a self-contained applicator head which is resiliently connected to a hand grip for limited movement in substantially all directions relative to the hand grip. A drive motor and an eccentric flyweight are mounted together within the applicator head for making it as a self-contained vibrating unit. The eccentric flyweight is connected to a motor output shaft in an eccentric relation thereto for imparting vibration to the applicator head upon rotation of the output shaft. Also mounted within the applicator head is a counterweight which provides dynamic balancing of the applicator head in such a manner as to coincide the center of mass of the entire applicator head with that of the flyweight in the axial direction of the output shaft.Type: GrantFiled: April 27, 1989Date of Patent: September 25, 1990Assignee: Matsushita Electric Works, Ltd.Inventors: Hironori Iwamoto, Shigeyuki Ikeda
