Title: Method for checking function of magnetic tape cassette and device
Inventor: MIZUTA AKIRA
IPC: G11B23/113
Filed: 1988-01-13
Abstract: PURPOSE:To improve a checking accuracy in the tape traveling function check of a magnetic tape cassette by fit-inserting a boss into a reel just after the engagement of an engaging/removing mechanism to the reel is canceled. CONSTITUTION:In a normal condition, an engaging/removing mechanism 10 is in an engaging position where a braking lever 24 is engaged with recessed parts 14a and 16a of reels 4 and 6 outer peripheries. On the other hand, when a releasing lever 22 is pushed up by a push-up pin 32, the releasing lever 22 and braking lever 24 are turned in resistance to a spring energization due to a braking spring 26, and the mechanism 10 is made into a releasing position to release the engagement of the braking lever 24 and the recessed parts 14a and 16a of the reels 4 and 6 outer peripheries. Just after the engagement of the reels 4 and 6 and the engaging/removing mechanism 10 is canceled, bosses 34 and 36 are fit-inserted into the reels 4 and 6. Thus, a fear, that a looseness is generated in a tape to such an extent that an adverse effect is exerted upon the checking accuracy since the reels are carelessly rotated, can be eliminated.

Title: Purifying device
Inventor: SAHO NORIHIDE
IPC: B03C1/00
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To perform a magnetic separation operation efficiently by decreasing the intensity of a magnetic field when the level of accumulation of a magnetic material in a magnetic filter is low and increasing the intensity of the magnetic field when the level of accumulation of the magnetic material is high, by controlling the generated magnetic field of a magnetic separation part during a purifying operation. SOLUTION: During a purifying operation, the generated magnetic field of an electromagnet in a magnetic separation part is controlled through controlling the values of currents supplied from power supplies 42a, 42b and the values of supplied currents are set at a low level when the level of accumulation of a magnetic material in high-gradient magnetic filters 48a, 48b, 48c, 48d is low to lessen the intensity of the generated magnetic fields in superconducting magnets 33a, 33b. Further, when the accumulation layer of the magnetic material increases in thickness, the values of supplied currents from the power supplies 42a, 42b are controlled to set the values of supplied currents at a high level to gradually increase the intensity of the generated magnetic fields in the superconducting magnets 33a, 33b.  Thus, it is possible to keep a magnetic power on the accumulation layer at a constant value, regardless of a distance in the thickness direction and, consequently, keep an attractive force for the magnetic material at a constant level. Therefore, the attraction efficiency is enhanced and the purifying efficiency is improved.

IPC: B23B51/10
Filed: 1989-01-12
Abstract: PURPOSE:To chamfer a through hole in hard and soft metal completely from a front surface by providing a rhomboid bite to the axial slot at the tip of a cylindrical rotating shaft with its center fixed rotatably to the slot walls, to position the bite by a centrifugal force. CONSTITUTION:With the rhomboid short diagonal line of a bite 27 faced in the direction of the periphery of a through hole 18, a rotating shaft 21 is pushed into a workpiece 19 from the front surface of the workpiece 19 until the bite comes out of the back surface B. When the rotating shaft 21 is turned at high speed, the direction of the bite 27 is altered by a centrifugal force to face its lingitudinal line in the direction of the periphery of the through hole. When the rotating shaft 21 is pulled upward, a cutting edge 28 provided on the opposed sides of the bite 27 is contacted on the corner section of the through hole 18 to chamfer it. After completing chamfering, the rotating shaft 21 is stopped and moved downward, and the short diagonal line of the bite 27 is faced in the direction of the periphery of the through hole 18 and the rotating shaft is pulled upward. Thus the chamfering is completed.
