20080245170Roller Screw - A roller screw is provided having a structure suitable for circulating rollers. The roller screw has a screw shaft 10-09-2008
20090030306Endoscope Shape Detecting Apparatus - A detecting apparatus includes: a change-over switch for switching on/off display of a scope model on a liquid crystal monitor; a position calculating portion for calculating respective positions of source coils; a scope model generating portion for generating a scope model of an electronic endoscope based on the respective positions of the source coils calculated by the position calculating portion; and a selector for selectively outputting to the liquid crystal monitor a display-pause-time image stored in a display-pause-time image storing portion and a scope model image from the scope model generating portion; and a control portion for controlling each of these portions. The detecting apparatus thus displays an insertion shape of the endoscope at a timing as needed.01-29-2009
20090084212SCREW DEVICE AND METHOD OF MANUFACTURING THE SAME - Provided is a screw device capable of preventing occurrence of any elevation change at a joint between a ball return path of a circulation member and a loaded ball rolling groove of a nut.04-02-2009
20090169139MOTION GUIDE DEVICE AND METHOD OF ASSEMBLING MOTION GUIDE DEVICE - A motion guide device is provided which is able to damp the moving block from vibrating in a direction perpendicular to an axis of the raceway rail.07-02-2009
20090234223Surgery Assisting Apparatus and Treatment Assisting Apparatus - According to the invention, an endoscope system as a surgery assisting apparatus includes a surgery apparatus for performing treatment by abdominal operation procedure on a region to be treated in a body of a patient, and a luminal organ shape detecting apparatus used for assisting (supporting) the abdominal operation procedure. The luminal organ shape detecting apparatus is used as blood vessel position notifying means when procedure is performed by inserting a probe as a luminal organ insertion probe into a blood vessel, for example. This allows the luminal organ irrespective of the treatment to be easily and surely detected and enables a smooth procedure to be performed.09-17-2009
20090249911SCREW DEVICE - The present invention provides a screw device enabling insulation of sounds occurring from the inside of the screw device when circulating rolling elements.10-08-2009
20090287047ENDOSCOPE APPARATUS - To facilitate a connection operation between a signal processing device and an endoscope apparatus in which a processing system that performs signal processing of image pickup signals of an electronic endoscope and a processing system that calculates an insertion shape of the endoscope are integrated, a scope connector 11-19-2009
20090293658LOW-NOISE SCREW DEVICE - Provided is a screw device capable of reducing noise generated therefrom.12-03-2009
