Title: Frequency output control circuit
Inventor: KOBAYASHI YASUKO
IPC: H03L3/00
Filed: 1993-03-11
Abstract: PURPOSE:To attain complete isolation at an output side with respect to a signal whose frequency is (f) by using a frequency divider control circuit so as to apply ON/OFF control to an output signal whose frequency is (f). CONSTITUTION:The control circuit is provided with an oscillator 1 oscillating a frequency signal whose frequency is a multiple of (n) of a reference frequency (f), a fixed frequency divider 2 frequency-dividing the output frequency nf of the oscillator 1 by (n) to generate the output frequency (f), and a frequency divider control circuit 3 applying ON/OFF control to an output whose frequency is (f). The fixed frequency divider 2 whose output is subjected to ON/OFF control by the frequency divider control circuit 3 applies 1/n frequency division to the frequency fn when its power supply is active. An undesired component is reduced from the output frequency (f) resulting from 1/n frequency division at a filter circuit 4 to provide an output. On the other hand, when the frequency divider control circuit 3 applies control for turning off the power supply of the fixed frequency divider 2, since the fixed frequency divider 2 is not active and applies no 1/n frequency division, the frequency (f) is not generated. Since the frequency (f) is not in existence at the output side, the output whose frequency is (f) is attenuated.

Title: Plasma chamber having cover-enclosed inner wall and antenna
Inventor: FUJITA HIDEKI
IPC: H05H3/02
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To prolong the lifetime of plasma and establish a stable operation by furnishing an insulative cover on the inner walls of a plasma chamber, and equipping an antenna with an insulative covering in the form of a sheath SOLUTION: Outside of a plasma chamber 4, a permanent magnet 5 in cylindrical form is installed as surrounding the chamber so that a magnetic field oriented in the vertical direction is produced. Thereby electrons make cyclotron motions so that microwaves are absorbed in resonance. The inner walls of the plasma chamber 4 are enclosed by a cover 6 in the form of a cylinder or disc. In an antenna 3, an insulative covering 7 in the form of sheath is inserted, while the chamber side of a vacuum connector 1 is protected with a connector cover 8. By ceramic covers, a space between the chamber and antenna are insulated in terms of DC, but it carries an induction current through insulative films, and therefore, a sufficient alternating magnetic field acts on the charged particles in the space.  Because the antenna is enclosed with the insulative covering, no sputtering will be made even with vibrations caused by the microwaves.

Title: Reel motor control system of magnetic tape device
Inventor: TAKEUCHI RIYUUICHI
IPC: G11B15/46
Filed: 1982-05-11
Abstract: PURPOSE:To prevent previously an excessive revolution of a take-up reel and the abnormal tension of a tape, by reducing suddenly the number of normal revolutions less than the normal set value when the revolution is detected with a supply reel. CONSTITUTION:At a control part 2 a take-up reel 5 is turned normal by a reel driving circuit 5a to collect the extra length of a tape of a vacuum post 10. In this case, the set value is changed by a detecting signal for the threshold value of a comparator of a control circuit for number of revolutions of a motor when the inertial revolution is detected with a supply reel 4. As a result, the number of revolutions of the motor is controlled to give the ordinary revolution to the reel 5. When the inertial revolution is detected with the reel 4, the reel 5 is driven a small number of revolutions. This prevents an accident due to the generation of the abnormal tension of the tape 1 which is produced by an excessive revolution when the reel 5 is stopped after detecting the end of collection of an extra length of the tape by means of an air switch 12.
