Abstract: PURPOSE:To facilitate the operation of a mass spectrograph by enabling the slit width to be minutely controlled by voltage applied to an electromechanical conversion element. CONSTITUTION:Electrode plates 20a and 20b are made by forming electrode films 32 and 33 on the main surfaces of a piezoelectric plate 31 and then forming electrode films 34 and 35 for applying voltage to the piezoelectric plate 31 in its thickness direction on the electrode films 32 and 33.

D.C. voltage is applied to the electrode films 34 and 35 from a D.C. power supply 37 the output voltage of which can be varied. When the output voltage of the D.C. power supply 37 is varied, the piezoelectric plate 31 expands or contracts in the thickness direction of the piezoelectric plate 31. Therefore the width (w1) of the discharge slit 21 can be minutely controlled without breaking the vacuum of the vacuum case. The width (w2) of the discharge slit 21 can also be minutely controlled independently of the width (w1).

Title: Method and apparatus for cooling theremoplastic resin film
Inventor: OSHIMA YOSHITOMO
IPC: B29C48/08
Filed: 1990-02-16
Abstract: PURPOSE:To prevent low molecular weight substances sublimed from a thermoplastic resin from being condensed on the surface of the resin, by blowing air against the counter-drum side of a thermoplastic resin film extruded onto the surface of a drum, while decelerating the flow of air by a decelerating filter disposed to cover two or more jet holes of an air nozzle and causing the flow velocity of the air to vary substantially continuously along the circumferential direction of the drum. CONSTITUTION:Air fed to an air supply part 6 of an air nozzle 5 is permitted to fill up a space between the supply part 6 and a decelerating filter 11. The air is decelerated and straightened by the filter 11, and is blown out from the entire surface of the filter 11 in the straightened state at a velocity much lower than the velocity at which it has been fed. The velocity of the air thus blown out at a position is greater as the position is nearer to a jet hole 10. Therefore, the velocity of the air blown out varies substantially continuously along the circumferential direction of a casting drum 2. The air blown out from the filter 11 collides against a thermoplastic resin film 12, thereby cooling the counter-drum side of the film 12, and bounces backward. In this case, portions of the air with higher velocity come round into portions of the air with lower velocity, so that the air is recovered into an exhaust part 7 entirely through parts 9 of the filter 11.

Title: High-density optical disk and its production method
Inventor: MIYAZAWA HIROSHI
IPC: G11B7/24067
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To produce high-density pit signals by a super resolution with a simple thin film structure and simple reproduction method and to improve repetitive durability by varying the Kerr rotating angle of pit parts and parts exclusive of these pit parts. SOLUTION: The optical interference structures of the first regions 201 and second regions 202 of the high-density optical disk vary. The enhancements of the Kerr rotating angles that the laser beam entering from a substrate side, therefore, vary. The Kerr rotating angles of the first region and the second region, consequently, vary in the state that a magnetic film is uniformly magnetized. The Kerr rotating angle of the magnetic layer in the high-temp. part behind the beam spot decreases if the region to be irradiated with the beam is increased up to T1 by increasing the laser power for the purpose of signal reproduction while applying the external magnetic fields on the magnetic layer. The mask region A401 where the Kerr rotating angle is lost appears in the final.  On the other hand, the temp. is still low in front of the beam spot and, therefore, the signal reproduction by the Kerr rotating angle from the aperture region B402 is possible.
