Title: Gas laser oscillator
Inventor: KOSUGI SHINICHIRO
IPC: H01S3/101
Filed: 1989-08-18
Abstract: PURPOSE:To prevent the deterioration of the quality of laser beams due to impulse waves, expansion waves and compressional waves by arranging an orifice plate into the aerodynamic window of laser beams, disposing a nozzle, a diameter of which is increased toward the orifice plate side, and providing the exhaust means of atmospheric air flowing into a cabin formed between these orifice plate and nozzle through a nozzle. CONSTITUTION:A laser beam B from the laser output section 1a of a gas laser oscillator 1 is introduced to an aerodynamic window 2, is reflected by a reflecting mirror 3a, and passes through the orifice 4a of an orifice plate 4. It reaches inside a cabin 5, passes through the conical nozzle 9a of a nozzle plate 9 and is reflected by a reflecting mirror 3b and applied to a work from a laser irradiating section. The atmospheric air sucked from the nozzle 9a in the cabin 5 is accelerated to supersonic speed at that time, but the nozzle 9a at the time is formed in the conical shape of a large diameter on the cabin 5 side. Accordingly, the atmospheric air is decelerated to subsonic speed, and impulse waves collide against a laser beam B emitted to the reflecting mirror 3b side through the nozzle 9a, but impulse waves vertically collide against the laser beam B, and impulse wave themselves are extremely thin, thus resulting in no turbulence in the laser beam B.

IPC: G11B5/17
Filed: 1986-09-10
Abstract: PURPOSE:To prevent an operation gap from expanding and to improve efficiency in terms of magnetic recording and reproducing by providing conductive patterns comprising a part of a coil winding on the surface where a nonmagnetic spacer in a multichannel magnetic head comprised by jointing plural head chips through the nonmagnetic spacer is jointed to a head chip. CONSTITUTION:A far shallow groove is linearly formed on the full width of the spacer 1 on both sides where the main cores 1 in the nonmagnetic spacer are jointed. Those sides are close to the sliding surface S of a magnetic recording and reproducing medium rather than the center. The plural linear conductive patterns 9 are formed in parallel on the bottom of the groove and on both sides apart from the center. The patterns 9 comprise the part becoming the side of the nonmagnetic spacer 4 for the coil winding 5 wound on the head chip. Thus the back side from the coil window 7 of the main core 1 can be comprised by jointing core halves, and no expansion of the operation gap 6 occurs in a manufacturing process. Since the coil 5 becomes close to the operation gap 6, the efficiency that the head records and reproduces magnetically is improved.

IPC: B23Q3/18
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To make the direction of a work uniform by rotating a joining body once or more, stopping the rotation and stopping the work in a specified direction. SOLUTION: The work 5 is pinched by a holding mechanism in the position opposing to the joining body 33. After the joining body 33 comes into contact with the work 5, a downward energizing force Fa is still applied to the joining body 33. The joining body 33 is rotated. The rotation is continued while searching the place wherein a joining flat surface 33a comes into face-contact with the inclined surface 5a. The joining flat surface 33a comes into face-contact with the inclined surface of the work 5 during the rotation. The work 5 rotates together with the joining body 33 from this point in time. And the joining body 33 is stopped in the same position as the rotation starting position. And the work is rotatably held from the radial direction of the rotation so as not to incline the work with respect to the rotation axis of the joining body.  By this way, the inclination of the work to the rotation axis is prevented and the work is surely positioned.
