IPC: G11B7/09
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain the optimum tracking control and servo control regardless of the installation state of a device by a method wherein the relative posture of an object lens to a pickup is detected and correction signals corresponding to the position detection result are supplied to a tracking control circuit and a traverse control circuit. SOLUTION: A tracking error signal obtained from a pickup device 1 is supplied to a posture detecting means 3 which is a position detector. The posture detecting means 3 supplies a posture correction signal corresponding to the relative position of an object lens to the pickup device 1 to a correction circuit 6. The correction circuit 6 calculates a correction signal which has a polarity corresponding to the direction of the shift of the detected position of the object lens and a value corresponding to the value of the shift and arithmetically generates a tracking correction signal and a traverse correction signal. The tracking correction signal and the traverse correction signal are supplied to a tracking control circuit 4 and a traverse control circuit 5 respectively and an optical pickup is driven to rotate by a spindle motor 8.

Title: Finishing method for doctoring
Inventor: TACHIBANA SHINYA
IPC: B41F9/16
Filed: 1990-03-29
Abstract: PURPOSE:To remove ink easily and surely from the tip of a doctor by a method wherein the doctor is parted temporarily from a printing press plate on finishing of the doctoring, and said doctor is made to touch again on and part from a portion of the printing press plate whereon the ink is not existing. CONSTITUTION:A doctor 1 ia retracted toward a space above a portion 32 of a printing press plate 3 whereon ink 2 ia not existing after being scraped off by doctoring, and is made to repeat touching on and parting from the portion 32. When the doctor 1 parts from a great volume of the ink 21 raked together by doctoring, the ink 22 is stuck in relatively large quantities to the tip of the doctor 1. And when the tip of the doctor 1 is made again to touch on the portion 32 whereon the ink 2 is not existing after being scraped off, the ink 22 is drawn by surface tension in either directions to the doctor 1 and to the printing press plate 3. On this occasion, as gravity acts on the direction toward the underlying printing press plate 3, the greater pert of the ink 22 is transferred to the side of the printing press plate 3, and thereby balance is established. As the doctor 1 ia drawn up in this balanced situation, the ink 22 is mostly stuck to the side of the printing press plate 3 that ia positioned in the same direction as that on which the gravity acts, and thereby the tip of the doctor 1 is almost saved from being stuck with the ink.

Title: Regeneration of ion exchange resin
Inventor: DOI MASAYOSHI
IPC: B01J49/00
Filed: 1978-07-07
Abstract: PURPOSE: To prevent the corrosion of the small tubes of steam generator in atomic power plant by making zero NaOH present in desalinated water by positioning the border of the cation and anion exchange resins separation layer of regenerator below the water collection tube.  
     CONSTITUTION: By positioning the border L of the cation and anion exchange resins C and A separation layer of the regenerator 1 below the water collection tube 4, NaOH is introduced from the upper inlet tube 2 and also HC is incroduced from the lower inlet tube 3 for regeneration. In this case, the preferred distance between the border L and the water collection tube 4 is 50±30mm. Thus, the anion resin A near the water collection tube 4 becomes R-C by HC and also the cation resin C becomes R-H without R-Na because of no influence of NaOH, by which the presence of NaOH in the desalinated water can be made zero and therefore the corrosion of the small tube of the inconel steam qenerator in PWR type atomic power plant can be prevented.

Abstract: PURPOSE:To predict the time required by the low temperature tank to reach target temperature by sampling the temperature in the low temperature tank at specific time intervals and finding the gradient of the temperature variation to time from a specific arithmetic expression by using the sampled values. CONSTITUTION:The temperature in the low temperature tank 1 is measured by a temperature sensor 3 and its measured value is A/D-converted 4 and sent to an arithmetic unit 5. The unit 5 samples the measured value at the specific time intervals according to the indication of a timer 6 and performs specific arithmetic processing. The relation between the temperature T in the low temperature tank 1 and the time (t) is approximated by T=a0e<-b(t-t0)>+C (a0, t0: constant indicating the performance of a refrigerator 2). Then T1=dT/dt is calculated from variation in the sampled value of the temperature T and the time variation of ln(-T1) is calculated from it to determine a constant (b) indicating a temperature variation characteristic. Then limit temperature C is determined. Then current lna, (a=a0e<bt0>) is determined from optional reference time (t) and current temperature T. Then the target temperature is substituted as the temperature T to calculate the arrival time (t).
