Title: Liquid crystal display device
Inventor: KAMOI SUMIO
IPC: G02F1/1333
Filed: 1989-08-01
Abstract: PURPOSE:To check the irregularity of color by forming a liquid crystal injection port near a sealing part and providing a liquid crystal introducing path which leads from the liquid crystal injection port to an effective display part outside the effective display part. CONSTITUTION:Flexible polymer film substrates 1 and 2 are provided as a constitution substrate. A sealing material 5 is interposed in a peripheral part and a liquid crystal layer is inserted and held between the substrates. The liquid crystal injection port 6 is formed near the sealing part made of the sealing material 5. The flow of the liquid crystal in the effective display part is checked from the injection port 6 to prevent the movement of a gap material. The liquid crystal introducing path partitioned from the effect display part side by a gap material movement prevention wall 7 communicates between the injection port 6 and the effective display part. By thus providing the liquid crystal introducing path, the movement of the gap material is effectively prevented in the effective display part at the time of injecting the liquid crystal, so that the gap material is uniformly dispersed, a cell gap is uniformized and the irregularity of the color is prevented from occurring.

Title: Radio wave absorber
Inventor: KURATA KEIKO
IPC: H05K9/00
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a radio wave absorber which is made of a composition obtained by mixing a resin with carbon black and carbon fiber, thereby improving radio wave absorbing characteristics in an L-band and an S-band. SOLUTION: This radio wave absorber is made of a composition obtained by mixing a resin with carbon black and carbon fiber. As the resin, a resin having characteristics such as strength, heat resistance, and moldability according to use is used. For example, chloroprene rubber, acrylonitrile-butadiene rubber, silicone resin, and the like can be mentioned. As for the carbon fiber which is mixed as well as carbon black, it is desirable that the fiber length lies within a range from 1μm to 5mm and the fiber diameter lies within a range from 0.1 to 50μm. If the content of carbon black and carbon fiber is 50weight% or less or the total content is 80weight% or less, deterioration in flexibility and a problem that a crack occurs in a molded body can be avoided.  Further, when a complex made of crystalline graphite and amorphous carbon black is used as carbon black, the thickness and the weight of the radio wave absorber can be reduced.
