Title: Turret condenser of microscope
Inventor: YOSHINAGA MAKOTO
IPC: G02B7/16
Filed: 1979-11-13
Abstract: PURPOSE: To make it possible to prevent forgetting to open the diaphragm and execute the microscopy exactly, by automatically making the diaphragm an opened state at the time of microscopy of the phase difference by means of the cam which is rotated in one body with the turret, and the lever which is interlocked with the cam, etc.  
     CONSTITUTION: The cam 3 is fixed to the turret 2. The first lever 9 which makes its one end 9a contact with the cam 3 and can be rotated to the right and left, and the second lever 10 which is always rotated in reverse are provided. The spring 11 is installed between the diaphragm ring 5 and the stopper 13 by making it pass through the through-hole 10b of the lever 10. In case when the long diameter of the cam 3 contacts with the lever 9 by turning the turret 2 under said constitution, the lever 10 is located so that it is rotated to the left and the spring 11 is tensed. Even if the diaphragm ring 5 is rotated to the right for exposure, it becomes an opened state by releasing a hand. Accordingly, if the positions of the turret 2 and the cam 3 are decided so that said state becomes the state at the time of detecting the phase difference, the diaphragm is automatically opened by only making the turret 2 conform with the phase difference detection. In this way, it can be prevented to execute microscopy of the phase difference without opening the diaphragm.

IPC: F17C3/04
Filed: 1979-11-15
Abstract: PURPOSE:To obtain a complete leak-resistance all over a facing wall by a method wherein a thick joint part is built by adhesives between the upper and lower plates of a joint part. CONSTITUTION:Facing sheets 7, 7a are fixed through an adiabatic layer or a low- temperature-retaining pipe 9 on the inside of the outer wall 2 of a storing tank for a low-temperature fluid such as LPG and the like. Sheet metal such as alminum is used for the facing sheets 7, 7a and the edge part (b) of a joint part or an overlapping part 8 is bent upward by about 25mm. and about 30 degrees. Adhesives 11 are filled under pressure into the space 10 of this joint part and fixed. Therefore, the  more external pressure is given to the joint part, the more properties of a wedge are shown and the more the adhesive force is increased. Even though the internal liquid leaks from the body, it does not permeate into the low-temperature retaining layer and sealability against liquid can be maintained.
