A plurality of cavities are perforated on one surface of the panel to increase the acoustical surface properties of the panel. In the construction of the panel the wood pulp is directed into a holding tank for a predetermined period of time in order to expand the wood fibers, and further in which a composite mixture is produced by introducing into the wood pulp predetermined quantitites of starch and wax.

Abstract: An image forming apparatus employs a control means for controlling a driving means such that the current supplied to the driving means is varied between the interval from the end of the acceleration of a scanning means in the advancing direction to the start of the returning of the scanning means and the interval from the start of the returning of the scanning means to the end of the acceleration of the scanning means in the advancing direction. Due to the employment of this control means, a large torque is produced by a moving means for the scanning means during the interval from the start of the returning of the scanning means to the end of the acceleration of the scanning means in the advancing direction. Accordingly, vibrations are suppressed at the end of the returning movement of the scanning means.

Abstract: A device for controlling a stop position of a movable member includes a movable member movable as far as a specified stop position, drive means for moving the movable member, detection means for detecting that the movable member reaches the specified stop position, timer means for setting a specified time, and control means responsive to detection means for suspending the drive means when the movable member reaches the specified stop position, setting the timer means, then allowing the drive means to drive again until the set time elapses.

Abstract: A loudspeaker enclosure is formed generally in the shape of a tetrahedron, having a triangular bottom panel and three upstanding triangular side panels. In a first embodiment, the lower edges of the three side panels are connected to the three edges of the bottom panel, and the upstanding edges of the side panels are connected together. One or more speakers are mounted in respective apertures formed through the front side panel of the enclosure such that the sound waves generated thereby are directed forwardly therefrom. Another speaker is supported within the enclosure facing generally downwardly, but is angled toward the front side panel of the enclosure. The sound waves generated by the downwardly facing speaker are emitted through an opening formed through the lower end of the front side panel.

A piano made in accordance with the present invention includes an improved bridge and soundboard arrangement at an upper end of an upright piano's plate comprising a bridge rail connected to a soundboard; a suspension bridge supported along a first edge portion of the bridge rail and supported along a second edge portion opposite the first edge portion by the plate; and a bridge bearing in contact with the suspension bridge and arranged to bear against the strings to transfer vibrations from the strings to the soundboard.

Abstract: A compound corrective lens for use in light exposure in the manufacture of color CRTs includes plurality of lens elements, each having an elementary surface, formed in combination a compound surface on the exit side of the lens, with steps formed at the boundaries between adjacent lens elements to connect edges of the elementary surfaces of the adjacent lens elements. The surfaces are so arranged that the steps falls from the elementary surface on the inner side closest to the optical axis of the lens) to the elementary surface on the outer side (farthest from the optical axis). With such an arrangement, the adverse effect of the steps covered with a light-absorbing layer is reduced. That is, the effective areas of the elementary surfaces are enlarged, and thus the distortion of the lens surface is suppressed.

Abstract: In a photographic camera, a cassette carrier having a chamber for receiving a film cassette is movable outwardly from the camera body to permit one to insert and remove the film cassette. A drive spindle for the film cassette and a coaxial gear are rotatably mounted on a spring-urged slider supported on the carrier. Datum projections extend from the camera body to enter the chamber when the carrier is moved to return the chamber to inside the camera body, to shift the cassette from a centered position in engagement with the drive spindle to a datum position in the chamber. Simultaneously, a datum stop located in the camera body abuts the slider to shift the slider with the cassette and to limit the extent to which the coaxial gear will mesh with a driving gear rotatably supported in the camera body.
