Title: Digital recording and reproducing device
Inventor: KAWAMURA TAKESHI
IPC: G11B20/10
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To rapidly optimize the phase of a clock by indirectly detecting a lost error and inserted error and controlling the clock phase to quantize a reproduced signal, by detecting the appearance frequency of data and controlling the phase of the sampling clock based on the appearance frequency. SOLUTION: By a frequency analysis circuit 16 of a waveform analysis circuit, a threshold giving the peak value of performance is specified, and a threshold changeover signal is outputted to a threshold producing circuit 17. By the threshold producing circuit 17, a switch is changed over with the threshold changeover signal to control the threshold voltage to be applied to a comparator circuit 12A. As the result, the threshold of a data detecting circuit 12 is set to the optimum value suppressing both of the inserted error and the lost error. When the threshold voltage of the data detecting circuit 12 is fixed to the optimum value, the phase control of the clock which is provided in the frequency analysis circuit 16 by a PLL circuit with a clock phase adjusting signal outputted to the PLL circuit, is performed next.  This clock phase is controlled by the analyzed result of the waveform analysis circuit, in which the threshold value has been optimized.

Title: Image forming device
Inventor: NAGAYAMA HARUHIKO
IPC: G03G15/08
Filed: 1991-06-05
Abstract: PURPOSE:To improve durability and image quality without changing the press- contacting force of a developing roller in the direction of a photosensitive body. CONSTITUTION:A motor 57 is attached to a developing case 51 and a crossed helical gear 59 attached to the shaft 52a of the developing roller 52 is driven via a worm gear 58. On the other hand, a motor 57 and a connecting plate for applying a developing bias 60 are electrically connected with a printer main body via a harness 61 and a connector 12. External force accompanying with driving does not act on a developing unit, so that fluctuations in a gap and the abnormal abrasion of a gap holding member can be prevented. Moreover, the removability of an image forming unit and a main body is improved, and a reduction ratio between the motor and a roller can be made high.
