摘要： PROBLEM TO BE SOLVED: To execute the observation of both direct and side views by simple switchover by making incident light from an objective optical system for direct viewing, or from an objective optical system for side viewing fall on a solid imaging element selectively. SOLUTION: Incident light from an objective lens 3 for direct viewing forms an image in a solid imaging element 19 through a crystal filter 17. Incident light from an objective lens 5 for side viewing is reflected in the direction of the incident light by a mirror 35 in a horizontal state without falling on the solid imaging element 19, thereby a direct view image in the axial direction of an endoscope is converted to image signals by the solid imaging element 19. Incident light from the side viewing objective lens 5 is reflected by the mirror 35 and forms an image in the solid imaging element 19 through a crystal filter 17, and it is converted to image signals and displayed on the monitor of a processor 53. In this case, incident light from the direct viewing objective lens 3 is intercepted and absorbed by a light interception plate 37 provided on the rear side of the mirror 35. Therefor, a side view image in the direction perpendicular to the axial direction of the endoscope can be observed.

摘要： PROBLEM TO BE SOLVED: To prevent metal contamination of a fluid generated by mechanical sliding of metal by composing a driving means so as to drive a valve element housed in a housing part by magnetic force arranged on an outside. SOLUTION: A control valve 5 is formed in such a constitution that a valve element 57 is sealed and housed in a housing part in fluid-sealing relation, the valve element 57 is magnetically connected and driven by a ring magnet 68 installed on a movable body 66 arranged on the outside of a seal member 51b. Namely, a ball screw 65 is rotated and driven by the driving source 63 of a driving mechanism 62 for driving the valve element 57 vertically, and thereby, the movable body 66 provided with a magnet 68 on a lower end side is moved vertically. Since the magnet 68 and a magnet 61 built in the valve body 57 are installed so as to install magnetic poles in a direction reverse to each other, attraction is applied between both magnets 68, 61. A shaft 69 for guiding vertical movement of the variable body 66 and for stopping rotation at the time of vertical movement of the movable body 66, is arranged on the lower side of the driving source 63 downward.

摘要： PURPOSE: To easily and surely wash the scope of an endoscope by providing the washer with a cabinet in which the scope of the endoscope is housed and a brush to wash the operating part of the scope, an introduction tube and a forceps mouth. CONSTITUTION: The scope 1 of the endoscope is inserted into the inside of the cabinet 2 of this washer, and the tip part 10a of the introduction tube 10 is mounted so as to be fitted in the fitting part 31 of a rotary disk 18. The brushes 3, 5 and 7 are rotated by driving motors 4, 6 and 8, and the operating part of the scope 1 is washed by jetting washing liquid from a sprinkler 11. Since the introduction tube 10 is covered in circular ring shape with the brush in the inside of an inner case 9, the introduction tube 10 is washed by rotating the motors and operating a pulley 12. Also, the brush 40 is rotated by driving a motor 33, and enters the inside of the forces mouth by the pressing force of a spring 41 at a part where the forceps mouth is located. The brush 40 enters the forceps mouth by driving a motor 34, and the forceps mouth is washed by moving it in a vertical direction.

摘要： PURPOSE:To provide a corpuscle measuring device able to accurately discriminate a flying direction of corpuscles floating in space. CONSTITUTION:Measuring light from a light source 1, in which intensity distribution is formed in a right triangle state with an aperture, is made to scan space with a scanner 4. Scattered light, scattering due to the passing of corpuscles in space scanned with the measuring light, is photographed with a CCD camera 8 to be picture-processed with a picture processing part 9. A flying direction of the corpuscles can be determined from a picture image formed by the scattered light, because the intensity distribution of the scattered light from the corpuscles passing the space is corresponding to the intensity distribution of the measuring light, due to the right triangle state of the intensity distribution of the measuring light.

摘要： PURPOSE:To surely perform a piercing and improve the service life of a lens as well by projecting a laser light form the surface side of the laser light trans mission material closely fitting a laser light absorbing material and working the laser light absorbing material or laser light transmission material. CONSTITUTION:The laser light 2 focused by a focusing lens 1 is irradiated on a laser light absorbing material 4 by transmitting a laser light transmission material 3 and this part is rapidly heated. The laser light transmission material 3 prevent the release of the vapor caused at the melt part of the laser light absorbing material 4 and raises the vapor pressure of the melt part. When the stress to be caused by this pressure become larger than the strength of the laser light transmission material 3 of laser lighth absorbing material 4, a hole is formed on either material. In this way, the hole can surely be formed.
