摘要： The present invention provides a runner crushing device which is capable of breaking runners of complicated shape, with no broken runners sticking to its blades, and which has an advantageous effect that broken runners can be completely recovered. The device is constituted of a receiving blade and a hydraulically operated pushing blade. The receiving blade includes a plurality of plate-like longitudinal receiving blades having a predetermined height, and a plurality of transverse receiving blades each disposed between adjacent plate-like longitudinal receiving blades in a substantially orthogonal relationship thereto. The pushing blade includes cross-shaped pushing blade single bodies having a predetermined height juxtaposed in a plurality of rows, with each pushing blade single body being capable of entering a blade space defined between the longitudinal receiving blades and the transverse receiving blades in the receiving blade.

摘要： A tetrahydronaphthalene derivative represented by the general formula (I) and a liquid crystal composition containing the same. A compound represented by the general formula (I) shows superior liquid crystallinity and co-solubility with conventional liquid crystal compounds and compositions. Furthermore, addition of such a compound enables the threshold voltage to be significantly reduced with almost no deleterious effect on the responsiveness. In addition, a compound of the present invention can also be easily produced industrially, is colorless, and is chemically stable. Consequently, liquid crystal compositions containing such a compound are extremely useful as liquid crystals, and are particularly suitable for liquid crystal displays requiring a wide operating temperature range, low voltage driving and a high response speed.
