Filed: 1989-07-05
Abstract: PURPOSE:To prevent a flexible magnetic disk from colliding with slide contact parts by forming an X-shaped projecting part to include a core part near a crossing point on the slide contact face of the slide contact parts. CONSTITUTION:On the slide contact face of the slide contact parts integrated with a magnetic head, the X-shaped projecting part (composed of a crossing point 3B, leg part 3C in an upstream direction and leg part 3D in a downstream direction) exists while including a core part 3A of the magnetic head near the crossing point and groove parts 3E-3G exist between these projecting parts. Accordingly, when a flexible magnetic disk 1 is rotated at high speed, the phenomenon of positive and negative pressure in an air current, which is generated respectively in the projecting parts 3B, 3C and 3D and groove part 3E between the abutted faces of a magnetic head 3, can be utilized in a well-balanced condition. Thus, the flexible magnetic disk is stably traveled and a satisfactory recording and reproducing characteristic can be acquired. Then, respective slide and contact faces are prevented from being damaged and durability can be improved.

In this way, the sliding material good in both of the sintering phases and joining state can be obtd. Moreover, since a plating stage is needless in the producing process, the process can be simplified.

Abstract: PURPOSE:To eliminate the need for turning on and off of a large DC extraction voltage by generating ions selectively in one region of electrodes in order to form an electrostatic image on a dielectric member. CONSTITUTION:The gas existing in the spacing 6 between the electrodes 5 and 5 provided apart from each other is selectively sufficiently heated and generates the ions in the periphery of the spacing if the potential changing with time is applied to said electrodes.

The 2nd potential is applied to the 3rd electrode 11 to electrostatically charge the dielectric member 9 in order to attract the ionized particles to the dielectric member 9. The need for turning on and off of the large DC extraction voltage is thereby eliminated.

Title: Laser oscillator
Inventor: NISHIO MITSUHIRO
IPC: H01S3/139
Filed: 1983-09-26
Abstract: PURPOSE:To reliably position a laser light emitted irrespective of laser oscillation or not by providing an absorber for absorbing carbon dioxide gas laser light for emitting in an exciter on the axis of a resonant mirror outside the mirror and passing the measuring laser light such as an alignment. CONSTITUTION:A control laser oscillator 6 is provided at the position coaxial with the axis 5 at the control laser light L2 emitted from the oscillator outside a water tank 17. Thus, carbon dioxide gas laser light L1 emitted from a carbon dioxide gas laser oscillator which has an alignment and a resonator mirror even during laser oscillation can be positioned. In other words, the light L1 passed through a passing hole 2 during laser oscillation in the alignment passes a transmission window 4, but is absorbed to the water 16 filled in the tank 17 and not emitted out. Similarly, the light L1 emitted from the resonator mirror passes the side wall 20 of a water tank 19, but is absorbed to the water 21 in the tank 19. Thus, even if the resonator mirror is thermally drifted, the control laser light of He-Ne can be propagated always coaxially with the carbon dioxide gas laser light thus displaced.
