Title: Automatic erasing circuit for recording at rotation variation
Inventor: NAKADAI KATSUO
IPC: G11B5/09
Filed: 1985-08-12
Abstract: PURPOSE:To erase a recorded signal automatically and effectively by providing a rotative speed monitor circuit which gives an unlock signal and a recorded signal erasing circuit which supplies an erasing signal to a recording head in response to the unlock signal to erase the recorded signal written in a track position. CONSTITUTION:If the rotative speed of a rotating recording medium is disturbed to get out of the lock range because disturbance is applied on the way of write, this state is detected by the rotative speed monitor circuit, and this circuit gives the unlock signal when the write period is terminated. This unlock signal is generated when the rotative speed of the rotating recording medium gets out of the lock range, and the unlock signal is held till the end. When the unlock signal is given when the write period is terminated, the recorded signal erasing circuit is operated in response to this unlock signal to erase the recorded signal written in the track position in the write period. In this case, the recording head is moved repeatedly on the recording track, which is formed in the write period by the head itself, and traces the recording track accurately to write an erasing signal on it. Thus, the signal is erased accurately and effectively.

Abstract: PROBLEM TO BE SOLVED: To provide a technique of producing no water droplets when rapidly evacuating a charge takeout chamber. SOLUTION: In the case that after material to be treated is carried in a charge takeout chamber 3 constituted so that it can be vacuum-evacuated, the inside is vacuum evacuated, wall surfaces 6 of the charge takeout chamber 3 are heated to the temperature range of >=50 deg.C and <=70 deg.C, and then the chamber 3 is opened in the air to carry the material to be treated therein, and when it is rapidly evacuated, moisture in the air is not adsorbed on the heated wall surface to lower moisture partial pressure.
