摘要： An audio signal encoding apparatus includes a device for compressing multiple-channel digital audio signals into compression-resultant multiple-channel signals respectively. The multiple-channel digital audio signals relate to a sampling frequency and a quantization bit number. The compression-resultant multiple-channel signals, a signal representative of the sampling frequency, and a signal representative of the quantization bit number are formatted into a formatting-resultant signal. The formatting-resultant signal contains a sub packet and a sync information portion. The sub packet contains at least portions of the compression-resultant multiple-channel signals. The sync information portion contains the signal representative of the sampling frequency and the signal representative of the quantization bit number.

摘要： A recording disc has a lead-in area and a data area. A scrambled version of a SID code word is read out from the lead-in area of the disc. The SID code word represents a producer of the disc. The readout scrambled version is de-scrambled to recover the SID code word. The recovered SID code word is collated with reference SID code words to decide whether or not the disc is legitimate. Main information is read out from the data area of the disc when it is decided that the disc is legitimate. Readout of the main information from the data area of the disc is inhibited when it is decided that the disc is not legitimate.

摘要： An image forming device which allows reducing a linear velocity ratio of a developing roller against a sensitive body, which enables a pole pitch of a magnetic field generating layer to be miniaturized, and which generates a uniform and adequately thick toner layer on the developing roller. A toner regulating element formed by a sheet metal material having elasticity and non-magnetic characteristics elastically contacts a surface of the developing roller. The developing roller has an elastic body layer and a magnetic field generating layer having a minute pole pitch. The toner regulating elements serves to regulate a thickness of the toner layer without vibration induced from the pole pitch of the magnetic field generating layer. Thus, the toner layer can be uniform and of an adequate thickness, and reducing the linear velocity ratio of the developing roller against the sensitive body does not generate any drawbacks.

摘要： A developing device which includes a first toner transporting roller, a second toner transporting roller to which toner is transported from the first toner transporting roller and an image bearing member such as a photoconductive drum or belt. Seals are located between the circumferential ends of one of the toner transporting rollers and a bottom portion of a toner hopper. When the seals are between the bottom of toner hopper and the first toner transporting roller, the first toner transporting roller is longer than the second toner transporting roller and the circumferential portions of the first toner transporting roller which contact the seals do not contact the second toner transporting roller. Alternatively, when the seals are between the bottom of toner hopper and the second toner transporting roller, the second toner transporting roller is longer than the first toner transporting roller and the circumferential portions of the second toner transporting roller which contact the seals do not contact the first toner transporting roller. Additionally, when the seals contact the second toner transporting roller, side seals may be placed against the ends of the first toner transporting roller. In both of these arrangements, the length of the second toner transporting roller is shorter than a length of an effective area of a photoconductive layer on the image bearing member.
