Filed: 1992-08-11
Abstract: PURPOSE:To prevent a magnetic tape from damage in the fast forwarding/ unwinding operation even when a failure is generated in a motor servo circuit, by stopping the supply of a rotation driving signal to be supplied to a reel motor, in the case a command specifying the tape speed becomes a specified speed specification. CONSTITUTION:In the magnetic tape, the maximum unwinding amount or fast forwarding amount of which is settled, the final controlled rotating speed of the reel 4 at the time when whole tape unwinding is finished becomes a specific rotating speed. So, when the command specifying the tape speed such as becoming lower than the specified speed is supplied to the motor servo circuit 8, the circuit 8 is decided as abnormal by a microcomputer 6a. With this result, a motor driver 9 is controlled by the microcomputer 6a so that the supply of rotation driving signal to be supplied to the reel motor 2 is stopped. Consequently, even if a runaway of the motor 2 is happened due to the abnormality generated on the circuit 8, the motor 2 is forcibly stopped, thereby the magnetic tape is never damaged.

Title: Fin separating device
Inventor: OYAMA YOSHITAKA
IPC: B26F3/02
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To obviate a fin removing device by providing a deburring means which is fixed in its slant posture at an acute angle to an installing surface of a table and has a chuck to sandwich fins of a mold and has a reciprocating pressure cylinder to pull the fins in the acute angle direction. SOLUTION: A fin removing means 9 moves a chuck 12 to the moving table 2 side by actuating a reciprocating pressure cylinder 11 in a condition where the chuck 12 is opened. A spool fin 44 is sandwiched by operating the chuck in a condition of entering the spool fin 44. Next, since the reciprocating pressure cylinder 11 retreats, all the fins of a mold 40 are pulled. At this time, since the fins of the mold 40 are pulled in a range of about 70 deg. to 85 deg. to a plane of the mold, they are torn off from the tensile side tip which most strongly receives tensile force among bitten-off fins 43. A part of the bitten-off fins of the mold 40 is torn off one after another, and the mold 40 and all the fins are separated from each other. Therefore, a fin remouing device can be dispensed with.
