Title: Surface treating method
Inventor: ONO TETSUO
IPC: H01L21/302
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of residues by suppressing the etching amount of a base material through repeated impression of a high-frequency voltage upon a sample, by dividing the amplitude of the voltage into a high portion and a low portion and adjusting the etching rate of a thermally oxidized film to a specific rate or higher. SOLUTION: A sample 107 is set up on a sample stage 108. In order to accelerate ions incident on the sample 107, it is practical to set the frequency of a high-frequency power source 109 in the range of 200 kHz to 20 MHz. A voltage is impressed upon the sample 107 from the power source 109 by dividing the amplitude of the voltage into a high portion (on) and a low portion (off, which is 0 volt amplitude in this case) as shown by the voltage waveform 110 of the power source 109. It can be seen that the density of acicular residues can be reduced to 50 pieces/μm2 or smaller, when the etching rate of an oxide film is adjusted to 7 nm/min or higher. The upper limit of the etching rate of the oxide film is 20 nm/min or slower. Therefore, the amount of the residues can be reduced, when the etching amount of a base material is suppressed.

Abstract: PURPOSE:To perform large flow control by means of a miniaturized valve by sticking two poles of magnets to the shaft of a rotary valve, arranging a pair of yokes opposing to the magnets, changing magnetic flux, and varying the opening degrees of the rotary valve. CONSTITUTION:First of all, in the state a solenoid is not energized, the magnet 3 and yokes 8a and 8b stuck to a shaft form a magnetic path, and the shaft stops in the state of (a). At this moment a valve is in a half opened state. In the next step, when electricity is conducted in the coil A of the solenoid in the direction of (A) (B), the magnetic flux generated in the solenoid flows in the yokes 8a and 8b, and a yoke becomes an N pole, and the other one becomes an S pole. As a result, the magnet 3 at the center position is rotated thus coming into the state of (b), for example. At this moment, the valve comes into completely closed state. In addition, when electricity is conducted in the coil (B) of the solenoid in the direction of (B) (C), the magnetic flux generated in the solenoid flows in the yokes 8a and 8b, and the magnet 3 at the center is rotated in the reverse direction thus coming into the state of (c). At this moment, the valve comes into the state of fully opened.

Title: Head supporting mechanism of floppy disk drive
Inventor: KUME KAZUNARI
IPC: G11B21/20
Filed: 1984-12-07
Abstract: PURPOSE:To attain stable writing/recording operation by providing the 1st and 2nd spring parts and moving a lower head almost horizontally at the time of head loading for descending the lower head by the pressing force of an upper head on the basis of two stages of deflection due to both the spring parts. CONSTITUTION:Respective parts of a supporting plate spring 34 are located almost on the same plane under the head unloading state. However, the supporting plate spring 34 generates the two stages of deflection and descends the lower head 28 almost in parallel at the head loading time when a floppy disk 10 is loaded and the upper head 30 applies pressing force to the lower head 28 through a disk 10. Namely, the 1st plate spring 34b is deflected cantilever-like from the base of a fixing part 34a fixed on a carriage 18, but the 2nd spring part 34c formed so as to be folded in the direction from the leading end of the 1st spring part 34b to the base of the fixing part 34a generates a twisting phenomenon at a connection part with the 1st spring part 34b, the deflected displacement of the 2nd spring part 34c compensates the cantilever displacement of the 1st spring part 34b. Consequently, the lower head 28 is descended always under parallel status.
