20140303440 | INSERTION ASSIST DEVICE, INSERTION BODY, AND INSERTION APPARATUS - An insertion assist device in an insertion apparatus, the insertion assist device provided outside an insertion body including a first flexible tube, a second flexible tube different from the first flexible tube, and a base including a small-diameter portion coupled to the first flexible tube and a large-diameter portion coupled to the second flexible tube and being larger in diameter than the small-diameter portion and in which a rotation force transmission portion disposed and rotated when rotation force of the rotation force transmission unit is transmitted to the rotation force transmission portion, includes: an inner cylindrical body meshing with the rotation force transmission portion and rotatable around the base while the rotation force transmission portion is disposed in the base; and a tube supporting the inner cylindrical body and configured to cover at least part of the first flexible tube while the inner cylindrical body is in mesh with the rotation force transmission portion. | 10-09-2014 |
20140330079 | LIVING BODY INTRODUCTION APPARATUS - In a living body introduction apparatus, an inner rotating cylinder is covered with a stretchable cover having an inner circumferential length shorter than an outer circumferential length of the inner rotating cylinder. A portion of the cover pushed out in a protruding form by a roller disposed on an outer circumferential surface of the inner rotating cylinder enters a circular groove formed inside an outer rotating cylinder. Rotation of the inner rotating cylinder circularly moves the protruding portion on the outer circumferential surface. The protruding cover portion pushes the circular groove to rotate the outer rotating cylinder. | 11-06-2014 |
20140350461 | AUXILIARY INSERTION AND REMOVAL TOOL AND ENDOSCOPE - A spiral rotary member includes a tubular main body section and a fin section. The spiral rotary member further includes a spiral tube section that is arranged on the main body section and arranged to be wound around a longitudinal axis in the same direction as the fin section or a direction opposite to the fin section; and a diameter change preventing section that prevents a diameter of the spiral tube section from expanding when the spiral tube section is wound in the same direction as the fin section, or prevents the diameter of the spiral tube section from contracting when the spiral tube section is wound in the direction opposite to the fin section. | 11-27-2014 |
20150133856 | AUXILIARY INSERTION AND REMOVAL DEVICE - The spiral rotary member includes a main body section, a fin section that is disposed on an outer peripheral surface of the main body section and spirally arranged around a longitudinal axis C and an X-ray cutoff section that cuts off X-rays. The X-ray cutoff section is arranged so that a clear region to be clearly imaged by an X-ray and an unclear region to be unclearly imaged by X-rays are distinguished under X-ray observation in a periaxial direction of the longitudinal axis of the spiral rotary member, the X-ray cutoff sections being further arranged on the same straight line along a longitudinal axis direction of the spiral rotary member or the X-ray cutoff section being further arranged in the form of a band. | 05-14-2015 |

20100165416 | ELECTRONIC BLACKBOARD - A copy button is pushed to output image data to an external storage medium, such as a USB memory. Then, a process for writing the image data in the USB memory is executed, and an image corresponding to the image data is printed. When the printed image is light, a density controlling button is pushed, and then, the copy button is pushed again. The image data is called up from a RAM, and a process for causing a density of the image data to be darker is executed, via a tone translator of the electronic blackboard. The image data on which image density control has been executed is written over the data previously stored in the USB memory. | 07-01-2010 |
