Title: Method of processing surround signal
Inventor: YAMAWAKI TAKUYA
IPC: H04S5/02
Filed: 2001-10-26
Abstract: PROBLEM TO BE SOLVED: To apply rear localization to the in-phase components of two-channel rear surround signals by means of a pair of speakers installed at the front. SOLUTION: A matrix 1 separates/extracts the respective in-phase components of a pair of right and left two-channel rear sound signals at the rear to generate an in-phase component signal za and a pair of signals, xa and ya, formed by isolating the in-phase component signal za from the pair of right and left rear surround signals. The sum signal xb and the difference signal yb of a pair of in-phase component signal-isolated signals, and the in-phase component signal za are processed by means of filters, 2a, 2b, 2c, respectively based on a head transfer function. In addition, the difference signal xd and the sum signal yd of a filtered signal xc and a filtered signal yc are generated.  The sum signal SLx of the difference signal xd and a filtered in-phase component signal zc and the difference signal SRy of the sum signal yd and the filtered in-phase component signal zc are assigned as a new pair of rear surround signals for sound image localization.

Title: Image forming device
Inventor: KONDO KAZUYOSHI
IPC: G03G21/00
Filed: 2001-10-26
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device in which accumulation of carrier on the entrance seal of a developing device, accompanying the reverse rotation of a photoreceptor drum, is prevented by setting the timing of the stop of the application of a reverse polarity bias. SOLUTION: When the photoreceptor drum 11 is rotated in the reverse direction, the reverse-polarity bias that attracts carrier to the photoreceptor drum 11 is not applied. The timing of the stop of the application of the reverse- polarity bias is set after the stop of the normal rotation of the photoreceptor drum 11 and before the start of the reverse rotation of it. After the stop of the normal rotation of the photoreceptor drum 11, the application of the reverse- polarity bias is stopped. Further, the provision of a means for detecting the stop of the normal rotation of the photoreceptor drum 11 and a means for detecting the application of a development bias enables the secure control of the operation described above. In addition, decreasing an absolute amount of developer entering a development area decreases that the carrier gets over the entrance seal 141.
