Abstract: A pattern memory stores plural accompaniment patterns for each of plural accompaniment components, and each of the accompaniment components is composed of one or more musical instrument parts. An operator is provided for selecting a desired accompaniment pattern for each of the components, and the accompaniment patterns correspond, in accordance with a predetermined rule, to different possible manners in which the operator is actuated, so that a specific accompaniment pattern corresponding to a manner in which the operator is actually actuated. A new accompaniment pattern is registered into the pattern memory in accordance with the predetermined rule. Information indicative of the predetermined rule may be shown on a display. The pattern memory may store accompaniment patterns for each of plural different accompaniment styles, and specific accompaniment patterns may by shared between the accompaniment styles.

Abstract: A normal automatic accompaniment performance is executed in accordance with an accompaniment pattern read out from a pattern memory. When a special performance is designated such as an intro, fill-in or ending performance, a modification suitable for the special performance is applied to a accompaniment pattern read out from the memory, so that the special performance is inserted in accordance with the thus-modified accompaniment pattern. At that time, the pattern may be modified by desired modifier data describing a manner of modifying the pattern. The pattern modification can be diversified by setting an individual modification condition to each musical instrument part of the accompaniment pattern in correspondence to the designated modifier. A memory is provided for storing a number of modifier data, and a further arrangement is provided for freely editing the modifier data stored in the memory.

Abstract: Food packaging-use formed articles including at least one layer of a 3 to 90 microns thickness which comprises a composition consisting of (A) polyvinyl alcohol resin having a degree of saponification of 60 to 95 mole % (A) and (B) a hydroxy containing compound falling within the range of from 3 weight parts of (B) to 100 weight parts of (A) to the saturated solubility of (B) in (A) and having a carbon dioxide/oxygen solubility ratio (SCO.sub.2 /SO.sub.2) of 30 or higher.

Abstract: A biaxially stretched heat-shrinkable laminated film is disclosed which possesses good heat-shrinkability, excellent melt hole resistance and heat-resistant sealing property (the heat resistance of a seal portion), and highly satisfactory cold resistance, retains transparency even after shrinkage, and serves advantageously as a wrap for packaging foodstuffs. The laminated film is provided as an oxygen barrier layer with a layer of a mixture of vinylidene chloride resin and a low melting point polyamide resin having a crystalline melting point of not higher than 210.degree. C. This mixed resin has been cross-linked by applying the electron beam to the laminate in a dosage in the range of 1 to 12 megarads. The laminated film exhibits a heat shrinkage percentage of not less than 15% at 90.degree. C. and excels in gas barrier property.

Abstract: Disclosed herein is a smoked food-package produced by packaging a foodstuff with a smokable packaging material and smoking the packaged foodstuff wherein the smokable packaging material comprises at least one layer of a mixture of 5 to 60% by weight of vinylidene chloride resin and 95 to 40% by weight of polyamide, said smokable packaging material having a practical smokability, high oxygen barrier property and high water vapor barrier property, and a smoking process.

Abstract: Disclosed herein are a resin composition comprising 5 to 95% by weight of a vinylidene chloride resin and 5 to 95% by weight of a polyamide resin having a low crystalline melting point of not higher than 210.degree. C. and a molded product of said resin composition.The molded product of the present invention shows a molded product excellent in gas-barrier property and impact strength at low temperature, particularly a film, sheet or container.Among the resin compositions of the present invention, since the composition having 60 to 95% by weight of vinylidene chloride resin is particularly rich in gas-barrier property, it is suitable for packaging foods, and since the composition having more than 40% by weight and not more than 95% by weight of polyamide resin is excellent particularly in impact strength at low temperature, it is suitable as the packaging material for use at an extremely low temperature.

Abstract: An automatic guidance system for an unmanned vehicle causes the unmanned vehicle to move to a destination by a combination of traveling along a preset course, and turning and stopping at predetermined positions. A running control unit is provided to determine optimal control values in such a manner that a running state of the unmanned vehicle after a predetermined period of time is predicted by changing control values set in a drive unit in accordance with state values (e.g., position information and heading angle information) representing the current running state, and that the running state after the predetermined period of time matches with the directed operation of the unmanned vehicle, thereby accurately guiding the unmanned vehicle along the preset path.
