Title: Detecting method for wear of magnetic head
Inventor: HAMA KOJI
IPC: G11B5/455
Filed: 1990-03-19
Abstract: PURPOSE:To detect the worn state of a head targeted to be detected by studying the change pattern of reproducing output in one or plutal times of still recording and reproduction based on the self-recording or reproduction of the head in a state where the feed of a magnetic tape is stopped. CONSTITUTION:When the feed of the magnetic tape(MT) is stopped, the still recording in first rotation is still-reproduced by scanning with the head A during 1/4 rotation when the head A scans the MT, and a reproducing voltage in a coil 8a generated by the still reproduction is inputted to a reproducing amplifier 9 via switches 6, 5, and a reproducing signal proportional to the reproducing voltage is outputted to a switch 11. The signal is inputted to a level detection circuit 13, and detection data is outputted to a control detection processing circuit 14. The circuit 14 detects the change pattern of the reproducing output of the head A, and compares it with the change pattern that is detection reference stored in advance, thereby, the automatic detection of the worn state of the head A can be performed.

Title: Vacuum processing apparatus
Inventor: TAKAHASHI KIYOSHI
IPC: B01J3/00
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To perform vent of a vacuum room without making dust fly up and in a relatively short time. SOLUTION: An unloading room 9 is partitioned into an upper space 11 and a lower space 12 by an air flow resistance element 10. In the unloading room 9, nitrogen gas is introduced into the upper space 11 from a vent hole 13 by a relatively high speed and slow vent is simultaneously performed from the lower space 12 through a vent hole 16. The upper space 11 is made thereby at a higher pressure than the lower space 12 and as a result, dust D on the bottom face of the lower space is prevented from flying up toward the upper space 11 and dust floating in the upper space 11 is rapidly lowered into the lower space 12.
