IPC: H04S1/00
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To obtain a wide listenable range in which listeners can feel a stereophonic sound field by reproducing binaural stereophonic sound signals by a group of couples of speakers through signal processing means which convert the binaural stereophonic sound signals into transaural stereophonic sound signals. SOLUTION: A 1st voice processing means 10 inputs a monaural voice signal and performs sound image localization operation to generate a binaural stereophonic sound signal. Then 2nd voice processing means 12-1 to 12-n generate transaural stereophonic sound signals from binaural stereophonic sound signals and drive couples of left and right speakers 14L-1 and 14R-1 to 14L-n and 14R-n respectively. The transaural stereophonic sound signals are so generated that the respective voice signals from speakers 14L-1 to 14L-n and the voice signals from the speakers 14R-1 to 14R-n have no crosstalk. Consequently, a natural sound field which provides wide-range stereophony can be obtained and listeners can feel the sound field providing stereophony.

Title: Apparatus for tightening side wall of packaging container
Inventor: ICHIHASHI YASUYUKI
IPC: B65B17/02
Filed: 1996-08-03
Abstract: PROBLEM TO BE SOLVED: To perform the continuous operation of a packaging line and reliably engage a portion of each container with a notch provided in a carton with a suitable pressing force, irrespective of the kind and size of the carton, by providing rotary rollers which are held in a posture that a part of each rotary roller faces the inside of a transfer path by an elastic force, and which retreat against the elastic force from the inside of the path toward the outside thereof by abutment with the carton. SOLUTION: When a carton 3 is transferred through a transfer path 11, rotary rollers 13 abut against corners, etc., of a top end of the carton 3 and tend to push away the carton from the inside of the transfer path 11 toward the outside thereof according to the transfer of the carton 3. This push-open force is transmitted from the rotary rollers 13 to swing arms 14, and each swing arm 14 swings against an elastically urging force of a tension spring 18 around a vertical shaft 17 so as to push the side, on which the rotary roller 13 is provided, toward a direction in which it is kept away from the transfer path 11, thereby increasing the urging force of the tension spring 18, which presses the rotary roller 13 against the inner side of the transfer path 11.  Accordingly, a portion of an outer periphery of a lower part of the side face of each container 1 is reliably fitted into each notch provided in the carton 3 to engage the parts of the containers 1 with the notches.

Title: Method for continuoulsy annealing coldolled stainless steel strip
Inventor: SHIOKAWA TAKASHI
IPC: C21D9/46
Filed: 1990-08-24
Abstract: PURPOSE:To obtain the strip uniform in quality over its entire length by providing a heat absorption promoter coating device on the inlet side of a continuous annealing furnace and changing the coating amt. in accordance with the position of the strip surface on the thicker side in the longitudinal direction of the furnace when the thickness of the strip is changed. CONSTITUTION:A heat absorption promotor coating device 2 is provided on the inlet side of a continuous annealing furnace 4. For example, when the preceding steel strip is thick and the preceding strip velocity is changed to the succeeding strip velocity on the inlet side of the furnace, the velocity is changed when a welding point A comes to the outlet side of the furnace, and the part directly below the welding point A of the succeeding strip is least annealed. The B point at a distance of the furnace length L from the welding point A enters the furnace at an appropriate velocity and is excellently annealed. The surface of the strip 1 is coated with the promotor by the coating device 2 in the amt. matching the deficient annealing. The coating begins at the A point and ends at the B point, and the coating amt. is maximized at the A point and reduced to zero at the B point. As a result, the entire length of the strip 1 is uniformly annealed.
