Title: Pneumatic radial tire for winter season
Inventor: YAKIDA MASANORI
IPC: B60C9/08
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent a crack from being produced in the groove bottom edge of a sipe by providing sub-sipes near the groove bottom edge of the sipe on the side wall of a block. SOLUTION: Each block 1 has a pair of sub-sipes 3 on the side wall along main groove 12 such that they sandwich the groove bottom edge 2e of a sipe 2 from the both sides thereof. The sub-sipes 3 are open to the side wall of the block 1 at a specified depth and they absorb, relax and disperse the stress concentrating at the groove bottom edge 2e of a sipe 2 when the tire is running by changing the volume of the sub-sipes 3 themselves. Therefore, they can prevent a crack from being produced in the groove bottom edge 2e by the dispersion action of the stress like this.

Abstract: PROBLEM TO BE SOLVED: To decide the correctional shape of a non-rectangular construction material and manufacture it at the molding time by compressing numerous wood chips to the specified crossectional shape using a roll molding device and joining a decorative board on the surface of a core part to be delivered continuously. SOLUTION: Plual wood chips 21 as a raw material are impregnated with a binder, then are dried and the dried wood chips 21 are loaded into a supply part 31 successively on a production line 30. Further, these wood chips are pressed between the rollers 35, 35 of a molding machine 33 into a specified correctional shape under compression and the compressed wood chips are heated using a heating device 37 to obtain a binding force between the wood chips 21. In addition, an adhesive is applied to the surface of core parts to be fed as a continuous material using an adhesive appellation device 40. After this process, a decorative board 12 sliced out of a decorative board supply device 45 is held between the rolls 51 of a molding device 50 while stacking the decorative board 12 on the surface of the core part.  The joint between the decorative board 12 and the core part surface is secured by heat through their passage in a heating device 57, and this particle board is cut to the specified length as a raw material for a construction material or furniture using a cutter. Thus it is possible to mold the particle board with a variation-rich correctional shape.

Filed: 1987-12-24
Abstract: PURPOSE:To enable black and white display in a wide temp. range at all times by bringing respective chiral agents of liquid crystal compsns. to be packed in a display cell and compensation cell into an enantiomer relation with each other. CONSTITUTION:The enantiomer is a pair of the compds. which are the same in molecular structure as each other, contain just one asymmetric carbon to make all of 4 kinds of substituents different and are in the enantiomeric relation with each other. The optically active pair is expressed by the formula. In the formula, R, S denote that the absolute dispositions of the asymmetric carbon are right and left. Such compds. are identical in the molecular structure and are, therefore, equal in thermal behavior to each other. Only the directions of the chiral degree are opposite and the absolute values thereof are the same. The optical rotatory powers of the compsns. are reversed on the right and left and the same helical pitch and the same dependency of the pitch (p) on the temp. are obtd. if such chiral agents are compounded at an equal ratio with the nematic liquid crystals to be packed in the display cell 1 and the compensation cell 2. The same d/p of the respective cells is thereby obtd. and the black and white display is enabled at all times from the low temp. to the high temp.
