摘要： PURPOSE:To realize a large area shading, and to make the maintenance and the management easier in a simple mechanism, by changing the level of the neighboring members in the reverse direction to each other, and arranging mutual side end edges to overlap with each other at a specific width, so as to cover the natural lighting surface. CONSTITUTION:A winding pipe is rotated in the direction of pulling back of a screen 20 by operating a motor. Then, the winding pipe is moved in the axial direction while rotating it, and a wire is wound up on the peripheral surface of the winding pipe in the spiral form. Then, a weight bar 3' is pulled out, and the screen 20 is pulled out from a winding shaft. On the other hand, the winding shaft is rotated in the screen winding direction, and the wire wound in a spiral form on the winding shaft is rewound. After that, the screen 20 is wound on the winding shaft until the weight bar 3' reaches near the winding shaft. Then, the wire is wound in the spiral form regularly on the winding pipe, and the moving stroke is secured so as to secure the winding amount of the wire, and the screen 20 can be pulled out.

摘要： PROBLEM TO BE SOLVED: To provide a tension control method for a large motor-driven roll blind to prevent the occurrence of slack. SOLUTION: A control device 8 provided with a wire winding motor 7 and a screen winding motor 6 is connected to an inverter 9 to control the number of revolutions to an arbitrary value. In the control device 8, during extension of a screen 2, tension transition only necessary at each process during winding of the screen 2 is set in such a manner that it can be outputted by a difference in the number of revolutions between the two motors 6 and 7, and tension is variable. During extension of the screen 2, coping with tension to change a value necessary to each process during winding of the screen 2 is practicable, and application of unnecessarily high tension is avoidable.

摘要： PROBLEM TO BE SOLVED: To constitute a system capable of adjusting reverberation time in a wide range without generating sound quality problem by emitting sound adjusted in its sound pressure not directly into a space in a hall but into an auxiliary space. SOLUTION: Sound waves propagated in a hall are recorded by a first recording microphone 6, and they are summed and inputted to a first frequency adjustment means and inputted to a first sound pressure adjustment means after adjusted suitable for an entertainment, and amplified to an extent of a set sound pressure before being emitted into a first auxiliary space S1 through a first loudspeaker 7. The emitted sound are diffused in the first auxiliary space S1 and re-emitted into the hall 1 through a first re-emitting opening part 9, wherein a sound quality and reverberation time can be adjusted. The sound are re-emitted from the first loudspeaker 7 and a plurality of re-emitting openings 9 located at different distances in non-correlative and incoherent sound to each other, and thus, non-artificial processed sound but natural sound are re-emitted into the hall 1.

摘要： PURPOSE: To provide a sound transmission device which can transmit sound to an aimed listener alone. CONSTITUTION: By mutually shifting phases of aural signals to be supplies to individual speakers 36 to form synthesis sound waves whose surface wavefronts 104 are concave on the side of sound collecting region 100 whereas convex on the side of nondirectional speakers 36, the surface wave front 104 gradually become small and the synthesis sound waves converge to the region 100 by adjusting phase differences among respective aural signals. Then, the amplitude of the aural signal to be fed to each speaker 36 is controlled so that the sound pressure of the sound emitted from each speaker 36 is of a hearing level or lower. Since the synthesis sound waves are formed by superposing the sound waves emitted from each speaker 36, the sound pressure of the sound converged to the region 100 is of the hearing level or higher.

摘要： PURPOSE: To detect a position of an object whose position is uncertainty and to extract a sound generated by the object based on its position. CONSTITUTION: When a person A moves, the inside of a room 50 is continuously photographed by plural television cameras 16, a sound extracting device recognizes its position based on the picture information regarding a region provided with specific feature quantity in a human head of which almost surface is covered by hair and which has much black part and almost spherical shape as a region corresponding to a head part P. Next, sound signals of each collected sound are delayed by a delay time in accordance with a distance between positions of each microphone 22 and a position of a head part P so that a voice part of the person A in a voice signal of a collected sound collected by plural microphones 22 is synchronized along time base. And only a voice of the person A is extracted by adding and averaging a delayed voice signal.

摘要： PROBLEM TO BE SOLVED: To obtain a judgment method in which the exfoliation of a wall tile from a building is judged by a low-cost apparatus, quickly, with high accuracy, quantitatively and easily by a method wherein the surface of the tile is vibrated mechanically and vibrating levels at a plurality of frequency bands are recorded so as to be discriminated by using a specific expression. SOLUTION: By using an exciter 1, a tile 5 is scanned by using an apparatus in which an oscillation exciting roller 2 and a receiving disk 3 connected to an accelerometer 4 are arranged in parallel. When the existence of an exfoliation is discrimineted, levels at respective vibration octave bands in a plurality of known sound places and exfoliated places are measured. For example, levels at seven octave bands from 64Hz to 4kHz are measured, vibration levels at seven frequency bands are designated respectively as x1 to x7 , and factors a1 to a7 are set by using the discriminating analysis of expression I. Then, the same measurement is executed to a wall surface to be investigated, obtained data is substituted for expression I, the value of Ya is compared with a threshold, and the existence of an exfoliation is estimated. Then, by using expression II, values of factors b1 to b7 are set, the value of Yb obtained by substituting data for expression II is compared with a threshold, and the position of an exfoliation face is estimated.
