Abstract: PURPOSE:To improve the accuracy of weighing and the durability by coating a fluorine polymer on a strain gage and coating a high-polymer material thereon so that the strain gage is moisture-proofed with no influence on the elongation or contraction of said gage. CONSTITUTION:The fluorine polymer 12 is thinly coated on the strain gage 7 adhered to the surface of each low-rigidity part 5b(6b)... of a strain inducing body 2 and the high-polymer material 13 such as silicone rubber or polyurethane is coated thereon.

Title: Liquid display device
Inventor: KUNIMOTO YOSHIKATSU
IPC: G02F1/133
Filed: 1986-10-27
Abstract: PURPOSE:To provide dot matrix type patterning with freedom and to prevent the generation of unevenness in illumination by masking the outside or inside of a transparent type liquid crystal display element. CONSTITUTION:A masking material 4 is arranged on the outside of the liquid crystal display element 5. A square dot where a common electrode 2 and a segment electrode 3 intersect with each other at right angles forms one lighting picture element. Since a masked part 4 is completely shutted (or half shutted), a circular dot part which is not apparently masked is displayed as a lighting picture element. Consequently, a wiring part can be designed wider than the lighting picture elements, so that the generation of unevenness in illumination can be prevented. Since the shapes of dots can be optionally selected only by a masking shape, a similar effect can be obtained even if the masking material is formed inside the liquid crystal display element.
