Patent number: 8822705Abstract: The present invention provides a highly safe pharmaceutical composition for preventing and/or treating bone disease, a pharmaceutical preparation comprising thereof, a health food comprising thereof, a functional food comprising thereof. Since the present invention comprises the arylheptanoid compound shown in the following formula (I) and the derivatives thereof, it enables to prevent and/or treat the bone disease. (In the formula (I), R1 and R5 are a functional group selected from the group consisting of a hydrogen atom, alkyl group having carbon numbers 1 to 3, monosaccharide and disaccharide; R2, R3, and R4 are a functional group selected from the group consisting of a hydrogen atom, an oxygen atom, alkyl group having carbon numbers 1 to 3, monosaccharide and disaccharide; R5 may be bound on meta-position against heptylene group of another aryl group to form a ring.Type: GrantFiled: January 30, 2009Date of Patent: September 2, 2014Inventors: Je-Tae Woo, Masato Ohta, Takayuki Yonezama, Toshiaki Teruya, Byung-Yoon Cha, Kazuo Nagai, Toshihiro Akihisa, Hiroyuki Akazawa

Patent number: 5009532Abstract: A paper feeding apparatus associated with a printer for storing a plurality of individual recording media and for controlling the release of individual recording media from a storage device toward a platen of the printer. A transmission mechanism couples rotation of the platen in a counterclockwise direction which rotates the paper feeding rollers in a clockwise direction for releasing the individual recording media from the storage device. Rotation of the platen in a clockwise direction halts rotation of the paper feeding rollers preventing further release of individual recording media from the storage device while rotating auxiliary paper feeding rollers in a counterclockwise direction for advancing the individual recording medium toward the platen. A release lever disengages the paper feeding rollers and auxiliary paper feeding mechanism to permit use of continuous print media.Type: GrantFiled: May 16, 1988Date of Patent: April 23, 1991Assignee: Seiko Epson CorporationInventors: Hiroyuki Akazawa, Toshihiro Imae

Patent number: 4602882Abstract: A serial printer includes a control circuit for driving the printer carriage. The control circuit detects the change of level of a home position signal in synchronism with a print position signal which is produced based upon occurrence of particular data selected out of a cycle of data for driving a step motor so as to increase the permissible range of variation in the change of the level of the home position signal that takes place due to mechanical vibrations differing in mode or phase.Type: GrantFiled: August 4, 1983Date of Patent: July 29, 1986Assignee: Seiko Epson CorporationInventor: Hiroyuki Akazawa

Patent number: 4525085Abstract: The print head of a serial printer includes a protruding plug which is seated and locked into a receptacle on a translating carriage. An endless belt has teeth engaged in a correspondingly contoured groove of the carriage for positive connection between carriage and belt, whereby the head traverses the printing medium for printing thereon. The platen is positively and simply held and includes a resin surface for impact of print wires. The gap between the head and platen is readily adjusted in steps by motion of a lever.Type: GrantFiled: September 30, 1982Date of Patent: June 25, 1985Assignee: Epson CorporationInventor: Hiroyuki Akazawa

Patent number: 4500023Abstract: A paper feeding apparatus for use in a printer is capable of feeding both continuous computer or fan-fold paper having holes in the peripheral edges thereof and single sheets of paper such as letter paper. The paper feeding apparatus includes a frame having a platen rotatably supported thereon and a guide shaft supported on the frame. First and second paper feeding members are disposed on the guide shaft and spaced apart for feeding a fan-fold paper along the peripheral edges thereof by means of the holes therealong. First and second guide members are disposed intermediate the first and second paper feeding members. The first and second paper guide members each have a first portion for guiding a continuous fan-fold paper fed by the first and second paper feeding members, a second portion for guiding a single sheet of paper while being inserted and fed into the printer and a third surface for guiding a single sheet of paper while it is being fed out of the printer, past the platen.Type: GrantFiled: August 18, 1982Date of Patent: February 19, 1985Assignees: Epson Corporation, Kabushiki Kaisha Suwa SeikoshaInventor: Hiroyuki Akazawa

Patent number: 4492484Abstract: A printing device for use in a wire dot printer having a plurality of printing wires. The printing device includes a frame and a carriage slidably supported on the frame for lateral translation thereacross. A printing head is supported on the carriage and includes a nose member which supports the plurality of printing wires. First and second holding members are disposed on the carriage so that the nose member is intermediate the first and second holding members. A ribbon mask constructed from an elastic material is disposed on the nose member. The ribbon mask is removably held between the first and second holding members and extends across the nose member.Type: GrantFiled: August 13, 1982Date of Patent: January 8, 1985Assignees: Epson Corporation, Okaya Kogyo Kabushiki Kaisha, Kabushiki Kaisha Suwa SeikoshaInventors: Hiroyuki Akazawa, Kazue Yoshiie

Patent number: 4196667Abstract: A print hammer having an improved head portion for striking a selected moving print character member in a line printing device is provided. The printing device prints when the print hammer strikes a print character member at a predetermined print position forcing the character member against an ink ribbon, a print paper and a platen. The head portion is formed with an inclined surface facing the direction of approaching adjacent character members to drive an adjacent character member striking the side of the print hammer around the print hammer for avoiding jamming and damage to character members and print hammers. In a preferred embodiment the head portion is substantially "V" shaped with the apex of the V disposed in a direction opposite to the movement of the print character members.Type: GrantFiled: March 23, 1978Date of Patent: April 8, 1980Assignee: Kabushiki Kaisha Suwa SeikoshaInventors: Akio Mitsuishi, Hiroyuki Akazawa, Kozo Ishizaka, Shinshu Seiki Kabushiki Kaisha

Patent number: 4173183Abstract: In a line printer character belt in which characters are mounted on flexible fingers which are struck by printing hammers toward a platen in the printing operation, the fingers are flexed toward the platen by a projection on the fingers or on a character block on which the fingers are mounted. Vibration subsequent to the printing operation is eliminated, thereby providing excellent printing quality free of dirt and ghosts.Type: GrantFiled: March 10, 1978Date of Patent: November 6, 1979Assignees: Kabushiki Kaisha Suwa Seikosha, Shinshu Seiki Kabushiki KaishaInventor: Hiroyuki Akazawa
