Title: Destaticizing charger for image forming device
Inventor: KATO SHINGO
IPC: G03G15/02
Filed: 1990-01-22
Abstract: PURPOSE:To obtain the charger which is small in electric power consumption and generates ozone in a smaller amt. by forming an air shutting-off film layer in the part on the outer periphery of a charge wire exclusive of the range approximately opposite to the aperture of a shielding case. CONSTITUTION:The air shutting-off film layer 8 is formed in the part on the periphery of the charge wire 4 exclusive of the range approximately opposite to the aperture of the shielding case 1. The charge wire 4 does not come into contact with the air in the range where the air shutting-off film layer 8 is formed when a high voltage is impressed to this charge wire 4 and, therefore, a corona discharge is not generated. The corona discharge is generated only in the range opposite to the aperture of the shielding case where the air shutting-off film layer 8 is not formed. The surface to be destaticized is thus effectively irradiated with the corona discharge and the corona discharge is utilized for the destaticization. An effective current ratio is, therefore, improved and while the electric power consumption is reduced, the amt. of the ozone to be generated is decreased in proportion thereto. The charger which is low in the electric power consumption and generates the ozone in the smaller amt. is obtd. in this way.

Title: Method for decoding viterbi
Inventor: KINOSHITA YUJI
IPC: G06F11/10
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To realize a viterbi decoder in which the number of times of memory access can be reduced, and of which memory power consumption can be reduced by executing ACS steps in parallel. SOLUTION: A viterbi decoder is provided with two branch metric calculators 1 and 2, two ACS circuits 3 and 4, and two path memory selectors 6 and 7, and the plural ACS circuits 3 and 4 are used for reducing the number of times of access to a memory 5 for a path metric. For example, when there are two paths passing through the same state at a time (n-1) and reaching different states at a time (n), and the ACS is executed to those paths, the path metric of the path reaching the time (n-1) is commonly necessary, and the ACS processings are operated in parallel so that the reading of the necessary path metric is necessary not plural times but only one time. Thus, the number of times of memory access is reduced, and memory power consumption is reduced.

Title: Transmission loss compensating system
Inventor: YAMAMURA KOJI
IPC: H04Q1/54
Filed: 1994-02-03
Abstract: PURPOSE:To perform stable loss compensation in the case of executing the connection of the public line to a leased line by identifying a loss on a transmission line corresponding to the level of a PB signal transmitted by a caller and providing an optimum control function for correcting that loss at the central office trunk(COT) of a telephone exchange. CONSTITUTION:Since the transmission level of PB signals transmitted from the telephone set of a call originating subscriber SUB A is regulated at a fixed value, the level of the PB signal arriving at the COT or a register sender PBRS of the central office trunk is detected to recognize the reduction of the level, namely, the loss at a public communication network from the call originating subscriber SUB A to the central office trunk COT. Then, based on the detected level, the compensation is performed corresponding to the degree of the loss fixedly set in advance, and the level is matched almost equally with the level at the time of transmission from an extension subscriber SUB C. Thus, even when the public communication network and a leased line communication network are connected, the satisfactory speaking level can be kept.
