Title: Method for removing film from magnetic recording medium
Inventor: FURUMIZO KAZUNAGA
IPC: G11B5/84
Filed: 1988-12-16
Abstract: PURPOSE:To easily and efficiently remove the thin magnetic film layer and thin protective film layer of the magnetic recording medium with a simple operation by treating the magnetic recording medium with an aq. dilute nitric acid soln. of a specific concn. or below. CONSTITUTION:The magnetic recording medium is obtd. by depositing and forming a (Cr) underlying layer, the thin magnetic film layer consisting of a Co alloy and the thin protective film layer on a substrate. The defective medium which is rejected in the product standards for the magnetic recording media is treated with the aq. nitric acid soln. having the concn. in a <=15wt.%, more preferably 5 to 15wt.% range to remove the thin magnetic film layer and the thin protective film layer formed thereon at the time of removing the films from the above-mentioned defective medium and recycling the medium.

Title: Method and equipment for measuring roll profile
Inventor: OKUNO MAKOTO
IPC: G01B17/06
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent generation of bubble in a water to be measured and deterioration of the measurement accuracy of a measuring equipment, by jetting the water to be measured constantly and increasing the flow rate thereof during measurement. SOLUTION: A predetermined quantity of water is supplied constantly through a water supply pipe 7 to an ultrasonic probe 10. At the time of measurement, a processing means 5 delivers a measurement start signal to a flow rate regulator 6a. The flow rate regulator 6a regulates the opening of a flow rate regulation valve 6b such that the jetting quantity of the ultrasonic probe 10 can be increased to a level for measuring the roll profile. Upon elapsing a predetermined time after delivering a measurement command signal to the flow rate regulator 6a, the processing means 5 transmits an ultrasonic wave to the ultrasonic probe 10 and starts measurement.  Upon finishing the measurement, the processing means 5 transmits a measurement end signal to the flow rate regulator 6a which returns the opening of the flow rate regulation valve 6b back to a low state thus returning to the non-measuring state.
