Patent JP-H07245972-A (JP)
Title: Transfer device
Inventor: KAMIYAMA KAZUHIKO
IPC: B65G27/16
Filed: 1994-03-04
Abstract: PURPOSE:To lower high-frequency voltage to low voltage, and to reduce power consumption by increasing the speed of a transferred member by the elastic deformation of a displacement transmission member mounted on a section abutted against the linear member of a diaphragm. CONSTITUTION:A comb-tooth-shaped displacement transmission member 3 formed of a friction material is interposed at the abutting point P1 of a diaphragm 1 and a movable rail 11. The displacement transmission member 3 is formed of engineering plastics having a high Young' s modulus, excellent heat resistance and superior workability. When an elliptic motion is conducted at the point P1 of the diaphragm 1, the elliptic motion is transmitted over the movable rail 11 through the displacement transmission member 3. The comb- tooth sections 5 of the displacement transmission member 3 are elastically deformed at that time, and the quantity of the elliptic motion worked is increased by the restoring force of the elastic deformation, thus augmenting the quantity of the movable rail 11 transferred. Accordingly, a shifter at high voltage need not be used as high-frequency voltage, thus reducing power consumption.

IPC: H04R3/00
Filed: 1986-03-17
Abstract: PURPOSE:To improve an acoustic effect due to a pseudo reverberation sound by attenuating the prescribed low pitched tone area of a pseudo reverberation signal and reproducing it together with an original signal. CONSTITUTION:The original signal outputted from an acoustic source 1 is inputted to a main amplifier 3 and a time delay device 4 through a preamplifier 2. The time delay device 4 applies a prescribed delay time to the original signal, outputs as the pseudo acoustic reverberation signal and the low pitched tone area in the pseudo acoustic reverberation signal is interrupted in a high pass filter 8. Accordingly, from main speakers 6R, 6L, a direct sound in which the entire tone area of the original signal is reproduced is emitted and from reverberation speakers 7R, 7L, the pseudo reverberation sound in which the pseudo reverberation signal excluding the low pitched tone area is reproduced is emitted. Thereby, the sound field effect is efficiently added by the middle and the high pitched tone components of the pseudo reverberation sound without offsetting the sound field effect making the distance to a sound source feel remote by the low pitched tone component of the pseudo reverberation sound.
