Abstract: A concrete tile of integral, one-piece construction has left side and right side portions of different coloring which extends through the entire thickness of the relatively thin, generally planar tile. An upper surface of the tile has a groove therein which separates the differently colored left side and right side portions. The left and right side portions have different lengths, providing the tile with a stepped front edge. A method of making the tile dispenses wet concrete having two different colors into a partitioned pug box for disposition onto opposite sides of a pallet, so that the two different colors reside on opposite sides of the pallet in side-by-side relation. The wet concrete is metered and compressed by a roller and shaped by a slipper to provide the concrete tile with a desired cross-sectional shape, following which the concrete is then chopped by a knife assembly to form the individual tiles with desired edge configurations.

Abstract: In a drawing false-twisting method, which draws a twisted yarn, heat-sets the drawn and twisted yarn, cools the yarn by making the yarn travel in contact with the surface of the guide groove of a cooling plate and untwists the yarn to obtain a textured bulk yarn, the yarn is moved laterally to spread the oil transferred from the yarn to the surface of the guide groove.

Abstract: An untwisting nozzle is provided with a cylindrical untwisting space for receiving whirling air currents, having a relatively small diameter, a cylindrical yarn sucking space for receiving suction air currents, having a relatively large diameter and formed in parallel to the untwisting space, and a slit interconnecting the untwisting space and the yarn sucking space.

Abstract: An automatic accompaniment device equipped with a CPU that controls, via a bus, a ROM that stores a plurality of rhythm patterns including introduction patterns, fill-in patterns and normal patterns. The device also includes a sound source circuit that generates musical sounds based on rhythm pattern data that is supplied after being selected by switches on an operation panel. In operation, the performer selects an introduction pattern to begin the automatic accompaniment. If the performer desires a shorter introduction, the performer activates a switch on the operation panel that causes a fill-in pattern to begin at a musically natural point in the introduction pattern. The fill-in pattern is shorter than the introduction pattern and provides a musically natural and smooth transition to the normal pattern. Thus, it is possible to end an introduction pattern at an optional point without imparting a musically unnatural quality to the automatic accompaniment.

Abstract: A pre-molded plastic package has encapsulation material removed so that an upper cavity is formed above the die and its associated wirebonds and a lower cavity is formed below the die attach pad and lead frame. Advantageously, the encapsulating material is removed without damaging the die, its associated wirebonds or the lead frame. An upper shield is then mounted on the top side over the still encapsulated die and wirebonds. Encapsulating material, such as epoxy, is then placed about the upper shield and cured. A lower shield is then mounted on the bottom side the die attach pad and lead frame. Encapsulating material is also placed over the lower shield and cured. Advantageously, the invention provides a process alternative whereby the shields can be installed at a very low per unit cost and in only minutes per unit without the need for custom tooling.
