摘要:
A noise control device which produces behind it an enlarged sound reducing region is disclosed. The device comprises a hollow structural body composed of a plurality of elongate hollow passages which are different in length and constructed such that the passage length is made the longest at a substantially center part in a vertical direction and is made gradually shorter from the center part toward upper and lower edges of the hollow structural body. The upper and lower edges allow direct propagation sound emitted from a noise source to pass thereover and therethrough.

A documentation apparatus includes: a selection unit which selects one function item from plural function items associated with documentation and selects one choice from plural selects included in the selected function item; a memory unit which stores the function item selected last and a non-selection candidate other than the selection candidate selected in the function item; and a function execution unit which performs function corresponding to the stored non-selection candidate by predetermined operation of the selection unit.

An improved head adjusting disk is disclosed which is adapted to be used for adjustment of the position of a head in a mechanism such as a floppy disk drive mechanism. On the improved head adjusting disk, two head position adjusting record tracks for adjustment of the position of a head are formed such that an outer circumferential edge of one of the record tracks and an inner circumferential edge of the other record track extend along a same circumference and that one of the two record tracks is formed to extend along a portion of one n'th (where n>1 and n=2) of the circumference while the other record track is formed to extend along the remaining (1-1/n) portion of the circumference, whereby individual signals reproduced from the two head position adjusting record tracks can be distinguished from each other by difference in duration thereof.

摘要:
A device for controlling a propagation direction of noise, which is preferably associated with a sound insulating wall to significantly improve its sound reducing effect of alleviating noise emitted from a noise source such as a railroad, highway and the like on which an electric car and automobiles run. The device comprises a hollow structural body composed of a plurality of elongated vertical hollow passages arranged at right angles to a substrate and spaced apart from each other by means of partition walls. The upper noise inlet side surface of the hollow passages face a propagation direction of noise emitted from the noise source and serve to refract and lag in phase the noise passed therethrough, thereby producing a sound reducing region located intermediate between a direct sound propagation and the refracted sound propagation. In one embodiment, a pair of hollow structural bodies are arranged in opposition to each other to form an arch type device. In another embodiment, the hollow structural body may be provided at its noise inlet or outlet side surface with an extension of the hollow passages.

The device comprises a hollow structural body composed of a plurality of elongate hollow passages superimposed one upon the other and spaced apart from each other.
