Title: Apparatus for evaluating liquid crystal cell
Inventor: SAKINAKA HIDEKI
IPC: G02F1/13
Filed: 1984-09-27
Abstract: PURPOSE:To attain the simplification of a leak checking process and the reduction of manual work, by scanning an integral mechanism of a liquid crystal cell pressing roller and a light detector such as a photodiode and detecting the contrast of a liquid crystal by the light detector. CONSTITUTION:When a leak is generated between the upper and lower substrates of a liquid crystal cell, a current becomes easy to flow and a leak current equal to or less than an actual display current flows to generate voltage drop and the contrast of a display part is lowered. Hereupon, a liquid crystal cell 4 is pressed along with a light detector 2 by the liquid crystal cell pressing roller 1 supported by a support frame body 3 to make a leak easy to generate while the measurement and comparison of contrast are performed by the light detector 2 to perform the check of the leak between the upper and lower substrates. An evaluation light source 5 is integrated with the support frame body 3 but may be arranged in the side opposite to the leak checking apparatus.

IPC: A47J27/00
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To maintain good demountability and mountability of a steam port and to keep good utility thereof. SOLUTION: When an upper member 52 is rotated and engaged with a lower member 51, a protrusion 79 of an outer convex part 71 gets over a protrusion of an inner convex part on the way and the completion of clamping can be confirmed by a click feeling. Further, even if the clamping of the lower member 51 and the upper member 52 becomes looser, the protrusion of the inner convex part is caught by the protrusion 79 of the outer convex part 71, and the upper member 52 is not separated. This effect of preventing the looseness is due to the protrusion 79 disposed in the vertical direction, and even if the size in the horizontal direction of a steam port 41 is varied, the engagement of the lower member 51 and the upper member 52 is not obstructed. Further, the engagement is not at all obstructed by variation of the size in the height direction of the steam port 41 in some degree.  Consequently, even if the engaging size of the lower member 51 and the upper member 52 is varied in some degree, the demountability and mountability of the steam port 41 are not spoiled.
