Title: Lens barrel system for microscope
Inventor: KOIKE TAKAHARU
IPC: G02B21/18
Filed: 1981-03-25
Abstract: PURPOSE: To miniaturize a lens barrel system, by varying the incident direction to a beam splitter of a binocular system between the observation mode and the shooting mode.  
     CONSTITUTION: The image beam given from an objective lens 21 is made incident to the face vertical to the optical axes of eyepieces 32 and 32' of a beam splitter 30 which forms an jentzch-type prism along with a binocular prism 31' and via an optical path folding reflector 22, a projector lens 23, a lock-up mirror 24, an optical path reflector 26, a relay lens 27 and an optical path folding lens 28 respectively. The image beam is then observed as a finder image through the lenses 32 and 32', and the photographing is carried out to a film 25 by means of the lock-up of the mirror 24. On the other hand, when only the observation is carried out, the lens 22 is shifted. As a result, the image beam is made incident to a different face of the splitter 30 from the face used for the shooting via an observing direction converting prism 29. Thus the binocular observation is carried out through the lenses 32 and 32'. In such constitution, no relay lens is required at the position right after the objective lens. And the number of the optical axis folding prisms is reduced, and the reduction of the light volume, etc. is prevented.

Abstract: PROBLEM TO BE SOLVED: To facilitate a worker's chipping work by fixing a crack forming material in an elongated state to plural reinforcement bars of a reinforcement bar cage erected in a drilled hole and arranging the same between reinforcement bars. SOLUTION: First, crack forming materials 1 are arranged between plural reinforcement bars 2 of a pile head part of a reinforcement bar cage worked by a reinforcement bar.
