Title: Backflow prevention device
Inventor: SUUMEN HIROYOSHI
IPC: B29C45/52
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of scoring on respective sliding sections of an injection device. SOLUTION: A backflow prevention device is provided with a metering ring section, a seal ring provided on the front end of the metering ring section, a screw head set on the metering section and provided with a head main body section and a small diameter section and a no-return ring 30 provided on the periphery of the small diameter section and provided with a protrusion 36 to be engaged with a notch formed on the head main body section. The outer diameter of the no-return ring 30 is formed smaller as it starts from the rear end and moves closer to the front end. In that case, as the outer diameter of the shut-off ring 30 is formed smaller as it moves from the rear end closer to the front end, the inner periphery face of a heating cylinder 11 is not rubbed with the outer peripheral face of the no-return ring 30.  The generation of scoring on the inner peripheral face of the heating cylinder 11 and the outer peripheral face of the shut-off ring 30, therefore, can be prevented by the arrangement.

Title: Objective lens
Inventor: SANO YOSHIAKI
IPC: G02B7/02
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To improve the assembly workability while preventing the deterioration in the observation performance of an objective lens by converting the rotary pressing force by tightening given from the outside into a rectilinear pressing force in the optical axis direction and transmitting this force to a lens group and a spacing frame. SOLUTION: The lens group 3 and the spacing frame are inserted into an external cylinder 6 and is tightened and fixed by a fixing frame 15. When a rotary frame 15a is rotated by a tool, etc., at this time, a lens retaining frame 15c is moved along the optical axis direction II which is its rotating axis direction by screwing of the rotary frame 15a and the lens retaining frame 15c. In such a case, the lens retaining frame 15c is prevented from being rotated and moved accompanying the rotation of the rotary frame 15a by the fitting of the front end on the other side of a stopping pin 15d embedded into the one external cylinder 6 into a groove 15c1.  The lens retaining frame 15c moves only rectilinearly along the optical axis direction II and the rotary pressing force transmitted to the rotary frame 15a is converted to the rectilinear pressing force in the optical axis direction II by the lens retaining frame 15c and this force is transmitted to the lens group 3.
