Title: Ferroelectric liquid crystal element
Inventor: HANIYU YUKIO
IPC: G02F1/1337
Filed: 1990-03-02
Abstract: PURPOSE:To display high-contrast images without generating after-images by forming a ferroelectric liquid crystal so as to have a specific orientation state. CONSTITUTION:This element has a pair of substrates 11a, 11b subjected to a uniaxial orientation treatment in the same direction. The four states having further a chevron structure in the C1 orientation states exist if the ferroelectric liquid crystal 15 is so formed as to have the orientation state expressed by theta<alpha+delta where the pretilt angle of the ferroelectric liquid crystal 15 is designated as alpha, the tilt angle as theta, and the angle of inclination of the Sm*C layer as delta. Of these four C1 states, the two states form a bistable state and the uniform state of the C1 orientation is higher in contrast than the bistable state in the C2 orientation. The large tilt angle theta is, therefore, generated by driving the liquid crystal in this uniform state. The high-contrast images are displayed in this way and the generation of the after-images is obviated.

Abstract: PURPOSE:To reduce the amount of a conductive agent used for preparing the positive electrode of  an organic electrolyte battery, and enhance the characteristics of the positive electrode by using a carbon fluoride positive electrode containing both carbon, which is a raw material for carbon  fluoride, as the main conductive agent, and carbon black as the auxiliary conductive agent. CONSTITUTION:The carbon fluoride positive electrode of a battery contains a mixed conductive  agent consisting of both carbon powder, which is a raw material for carbon fluoride, as the main  conductive agent, and carbon black as the auxiliary conductive agent. For instance, carbon fluoride powder prepared by subjecting petroleum coke to halogenation with fluorine, petroleum coke,  acetylene black, and a binding agent made of an aqueous dispersion of a styrene-butadiene rubber  (containing 50wt% of the resin) are mixed in a ratio by weight of 100:10:10:12, before water  contained in the mixture is evaporated. Following that, thus prepared mixture is compressed with  a collector made of a titanium net buried in it, thereby a positive electrode of 1mm. thickness being  obtained. The battery is constituted by combining thus obtained positive electrode with both a  negative electrode made of a light metal and an organic electrolyte. Through the means mentioned above, only a small amount of the former conductive agent is used in preparing the positive electrode. Besides, the discharge characteristic of the positive electrode is enhanced, since the  former conductive agent is mixed well with the active material of the positive electrode.

Title: Pressure vessel for use in compressor or the like
Inventor: MORITA TSUYOSHI
IPC: F16J12/00
Filed: 1981-04-03
Abstract: PURPOSE:To reduce the shearing stress and bending moment caused at the portion where a shell and a shell plate are welded together, by fitting a ring to the outside of a shell member, the inner diameter of said ring being equal to or smaller than the outer diameter of the shell member. CONSTITUTION:An O-ring 12 is fitted to the outside of a shell 1 having a thickness t in the manner of satisfying the following relationship, H>=2h/3, where H is the distance between the lower end face of the ring 12 and the inner surface of the shell 1 at its top and h is the distance between the inner surface of a shell plate 2 and the inner surface of the shell 1 at its top. In case that the thickness T of the ring 12 is sufficiently large (however, r<=T<5t), the shearing stress produced between weld bead 3 and the shell plate 2 by the rigidity of the ring 12 when an internal pressure P is produced in a compressor is reduced by about 2pirHp. Further, since the shell 1 is retained firmly by the ring 12, the portion of the shell plate 2 located lower than the ring 12 is protected against deformation even if a high internal pressure is acted, so that almost no bending moment is acted to the weld bead 3.
