Patent number: 9366401Abstract: The lighting system 1 includes a light emitting unit 4 including light emitting diodes, and a securing member 5 for securing the light emitting unit 4 to a head of a healthcare worker. The radiation of light from the light emitting unit 4 eliminates the need for a shadowless lamp. When the light emitting unit 4 is fixed to the head, the light emitting unit 4 moves with the movement of the healthcare worker, and furthermore, when the healthcare worker moves his or her head, the direction of light radiation can be changed as desired. The use of an auxiliary lighting unit 6 and a camera 22 can provide safe surgery.Type: GrantFiled: July 15, 2009Date of Patent: June 14, 2016Assignee: LIMITED LIABILITY COMPANY JAPAN MEDICAL CREATIVEInventors: Isamu Koyama, Takeshi Tanaka, Shuro Hayashi

Patent number: 8231642Abstract: An intestinal anastomotic surgery aid 1 is constituted with a cylindrical portion 40 for covering the proximal end side of an engaging rod 28, and a cover portion 41 that extends from the cylindrical portion 40 towards the distal end side of the engaging rod 28. The proximal end part of the cylindrical portion 40 is inserted to a recessed portion 26 of a device main body 21 to be held to the device main body 21. The anus-side piece of the intestine is tied with a suture to be held to the outer face of the cylindrical portion 40.Type: GrantFiled: March 31, 2011Date of Patent: July 31, 2012Assignee: JMS Co., Ltd.Inventors: Isamu Koyama, Shuro Hayashi

Publication number: 20070175481Abstract: A tubular member 2 is formed of a resin material so as to have an inner passageway 2. A thin plate is shaped into a spiral along the perimeter of the tubular member 2 to form a reinforcement member 3. The reinforcement member 3 is buried in a peripheral wall 2a of the tubular member 2. The tubular member 2 and the reinforcement member 3 have curved shapes conformable to the shape of the pharynx 100. The tubular member 2 and the reinforcement member 3 are inserted from the oral cavity 102 into the pharynx 100 and retained there. A medical instrument is guided to the esophagus 103 through an inner passageway 2b of the tubular member 2.Type: ApplicationFiled: March 31, 2005Publication date: August 2, 2007Applicant: JMS CO., Ltd.Inventors: Isamu Koyama, Shuro Hayashi

Patent number: 5926390Abstract: A programmed temperature controller including a difference detector which detects a temperature difference .DELTA.T between a quick-response temperature TC2 and a slow-response temperature TC3 at a quickly-responding portion and a slowly-responding portion of a workpiece (e.g., on the surface and core portions thereof). Also included is a comparator which compares the temperature difference .DELTA.T against an allowable difference limit preset by a difference setter. When the temperature difference .DELTA.t is found to be outside the allowable difference limit, a slope operator is actuated by the comparator, so as to calculate a slope of temperature change with respect to time of a program pattern PP which keeps the temperature difference .DELTA.t within the allowable limit. The above-mentioned slope in the program pattern PP is modified to the calculated value, and the temperature difference .DELTA.T is maintained within the allowable difference limit.Type: GrantFiled: March 28, 1997Date of Patent: July 20, 1999Assignee: Ohkura Electric Co., Ltd.Inventor: Isamu Koyama

Patent number: 5743464Abstract: A temperature program pattern PP for desired change of surface temperature TC1 of a work 11 with time is set by a temperature setter 31. Work temperature-difference .DELTA.t.sub.pv between the surface temperature TC1 and inside temperature TC2 of the work 11 is determined by a difference detector 34. Set value of the above temperature-difference .DELTA.t.sub.sp is given by a difference setter 35 in the form of a difference pattern DP of its change with the above surface temperature TC1. For each actual surface temperature TC1, the work temperature-difference .DELTA.t.sub.pv is compared against its set value on the difference pattern DP by a comparator 36. A slope operator 37 responds to the output from the comparator 36 and modifies slope of the temperature program pattern PP so as to cause the work temperature-difference .DELTA.t.sub.pv to follow the difference pattern DP.Type: GrantFiled: April 17, 1997Date of Patent: April 28, 1998Assignee: Ohkura Electric Co., Ltr.Inventor: Isamu Koyama

Patent number: 4966384Abstract: A suspension member mounting structure for mounting on a vehicle body a suspension member, with which left and right suspension arms each supporting a wheel are connected, through a front cushion group and a rear cushion group. The front cushion group has two cushion mounts attached to two positions of the suspension member in front of a rotary axis of the wheels and the rear cushion group has two cushion mounts attached to two positions of the suspension member behind the rotary axis of the wheels. Each cushion mount of the front cushion group is disposed to have a hole first, through which a bolt extends, extending vertically of the vehicle body and each cushion mount of the rear cushion group is disposed to have a second hole, through which a bolt extends, extending longitudinally of the vehicle body.Type: GrantFiled: May 2, 1989Date of Patent: October 30, 1990Assignee: Toyota Jidosha Kabushiki KaishaInventors: Terumasa Endo, Hiroshi Naruse, Hideo Nagaya, Hideaki Tsushima, Isamu Koyama, Yoji Matsumoto
