Title: Electrophotographic printer provided with paper positional deviation correction mechanism
Inventor: NAGURA MAKOTO
IPC: G03G15/00
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a compact inexpensive paper positional deviation correction mechanism which can be mounted even on a compact electrophotographic printer as well. SOLUTION: At the time of printing, a pressure roll for fixing 2 is pressed on a heating roll 1 with a pair of springs 16a and 16b and a pair of arms 14a and 14b. When a cam shaft 19 is rotated in a fixed direction with a motor 20, during nonprinting, cams 15a and 15b push the arms 14a and 14b against the force of the springs 16a and 16b to separate the pressure roll 2 from the heating roll 1. Since the phases or shapes of the cams 15a and 15b are difference from each other, when a printing paper is positionally deviated during a printing operation, the rotation of the motor 20 is controlled within a very small range, so that the mutual lifting quantities of the cams 15a and 15b with respect to the pressure roll are slightly different and a delicate difference in pressing force between both ends of the roll 2 is made.  Thus, the positional deviation of the printing paper can be corrected.

Abstract: PURPOSE: To improve the processing capacity while preventing the decrease in the magnetic characteristics by processing the molded form of a rare earth permanent magnet while being dipped in mineral oil, synthetic oil or vegetable oil. CONSTITUTION: Before processing, a movable table 6 is lifted by a driving shaft 8 from the surface of processing solution (mineral oil, synthetic coil or vegetable oil) 2, a molded form 3 is fixed to a spacer 3 at this position, and assembled with the table 6. Then, after a working blade 4 is arrived at a predetermined rotation, the table 6 is pressed down by the shaft 8, and hence the form 3 is brought into contact with the blade 4 and cut. Cuttings generated by the cutting are transferred together with the solution 2 by a circulating pump 10 via a tube 1 to a cutting recovering unit 12. The solution 2 in which the cuttings are removed is again returned to a processing tank 1. When the cutting is completed, the table 6 is again lifted above the surface of the solution 2, and the form 3 in which the processing is finished is removed.  Thus, the processing capacity can be improved while preventing the decrease in magnetic characteristics due to the reaction with oxygen.

Title: Pollution detector for surface of probe
Inventor: SHIMIZU KAZUO
IPC: G01N27/00
Filed: 1987-12-18
Abstract: PURPOSE:To detect the degree of pollution of the surface of a probe electrode polluted by ionizing substance within a plasma, by utilizing a hysteresis characteristic as generated when the surface of a probe is polluted and a threshold of a current amplitude discriminator circuit. CONSTITUTION:A voltage Vp is applied to probe electrodes P1 and P2 with a sweep voltage generator 1 and a probe current Ip presently flowing is detected 2. As the probe current Ip increases to reach a threshold Pps with a rise in a sweep voltage, a sample holding circuit 14 holds a sweep output Vp1 at the moment and when it reaches the threshold again with a drop therein, a sample holding circuit 15 holds a weep output Vp2 at the moment. A subtraction circuit 16 gives a difference (Vp2-Vp1) between both outputs of the sample holding circuits. With such an arrangement, when the surface of the probe is polluted and a hysteresis appears in a probe characteristic, a detection signal (Vp2-Vp1) is generated.

Title: Defect managing method for disk and disk recording and reproducing device
Inventor: SASAKI SHINJI
IPC: G11B20/18
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To surely make a device accessable to succeeding sectors even when a defect whose track can not be traced physically is present by detecting a defective sector whose track can not be traced physically and registering the defective sector and one sector succeeding to the defective sector as defective sectors. SOLUTION: Whether sector addresses are read out normally or not is judged in a first error judgement and when a sector is judged that there is an error in the sector, the sector is registered in a PDL(primary defect list) as a defective sector. Thereafter, the reading of the data written from a leading sector is performed. Whether the writing is successful or not is judged in a second error judgement. When an error is present, the sector is registered in an SDL (secondary defect list) as the defective sector. Thus, since even when a defective sector whose track can not be traced exists, the sector succeeding to the sector is also register in the PDL (or SDL) as a defective sector, a situation in which this device can not make access to succeeding sectors is avoided.
