Abstract: PURPOSE:To facilitate the maintenance and the inspection of a centrifugal clarifier, by providing a nozzle so as to position the leading end thereof in the vicinity of the liquid supply opening of a receiving container without piercing said receiving container by the nozzle to eliminate a mechanism for moving the nozzle. CONSTITUTION:The nozzle 34 fixedly attached to a casing 29 is terminated in the vicinity of the terminal end of a treating liquid supply cylinder 33 and the axial line thereof is aligned with the axial line of the treating liquid supply cylinder 33. In this structure, when a liquid contacting part after dye removal is withdrawn to an amber zone, it may be only hung up by a crane in such a condition that a wire rope is engaged with a hanging ring 48 because the nozzle 34 is not connected to a receiving container 32. In addition, because a treating liquid supplied from the nozzle 34 is injected under relatively high pressure, the leakage of the liquid is not generated but, when the treating liquid leaks to the outside of the container by some possibility by the reduced pressure generated when the supply of the liquid is started or stopped, the leaked liquid is returned to a treating liquid tank from a recovery part 38 provided to the bottom of the supply cylinder 33.

IPC: G11B5/02
Filed: 1982-08-18
Abstract: PURPOSE:To avoid deterioration of the reproduced sound quality, by superposing the discriminating signal corresponding to the prescribed recording signal processing on an input signal when an audio signal is recorded and detecting the discriminating signal to perform the corresponding reproducing signal processing when the audio signal is reproduced. CONSTITUTION:The audio signal is recorded to a recording/reproducing head 4 via a selection switch S1, a recording ampifier 1 and a changeover switch S3 in a recording time of normal processing. While the audio signal is supplied to a recording NR (noise reduction) circuit 2 via the selection switch circuit S1 in a recording time of the NR processing. Thus the frequency characteristics are compensated for the audio signal. In this case, a discriminating signal given from a discriminating signal generating circuit 3 is superposed on an output signal and then supplied to the head 4 via the amplifier 1 and a changeover switch S3. If a reproduced signal contains a discriminating signal for NR processing, a selection switch circuit S2 is driven via a filter circuit 6 and a discriminating signal detecting circuit 7. The reproduced signal of the circuit 6 is supplied to a reproduced NR circuit 8. Thus the frequency characteristics are compensated for a reproduced signal, and this reproduced signal is delivered to an output amplifier.

Abstract: PURPOSE:To prevent a copying loss by comparing size of a recording paper in case of interruption copying with that of the recording paper befor the interruption copying, and giving an alarm when the size is different. CONSTITUTION:The size of a recording paper before the interruption copying, which is input to the port C and is stored in the memory (RAM) is compared with that of a recording paper of interruption copying at the time when the interruption has been finished. And, when the size is different, an H level signal is output from the terminals G0, G1 of the port G, and the alarm lamp 14 showing that the cassette size is different, and the warning lamp 15 for refraining the copying operation are turned on. In this way, an operator notices that the cassette has not been returned to its orginal position, or the recording paper selective button has not been pushed so that the original recording paper can be selected, and therefore a copying loss can be prevented.
