    • A method is disclosed for manufacturing a lens array optical system including a flat glass plate and lenses each of which has a flat surface and a curved surface. The method includes the steps of removably fixing each lens with a first adhesive agent to a lens holder having lens holding portions corresponding to the curved surfaces of the lenses, polishing the flat surface of the lenses and the lens holder so that the polished flat surface of the lenses are flush with a polished flat surface of the lens holder, fixing the lenses to said flat glass plate with a second adhesive agent by pressing the lenses against the flat glass plate and hardening the second adhesive agent, and removing the lens holder from the lenses.

    • A method of making a magnetic recording and/or reproducing head having a head support and a head core. The head core is inserted in a slit defined in the head support and is retained in position on the head support by means of a fixing jig to hold the head core immovable relative to the head support. Thereafter, a glass frit for temporarily fixing the head core relative to the head support is fused by the application of a laser beam to partially connect the head core and the head support together. After the fixing jig has been removed and a glass frit has been mounted on the head support so as to cover the slit above the head core, the assembly is loaded into a heating furnace to fuse the glass frit thereby to permanently interlock the head core and the head support together.
    • 制造具有头部支撑件和头部芯部的磁性记录和/或再现头部的方法。 头部芯部插入限定在头部支撑件中的狭缝中,并且通过固定夹具保持在头部支撑件上的适当位置,以保持头部芯部相对于头部支撑件不可移动。 此后,通过施加激光束将头芯相对于头部支撑件临时固定的玻璃料熔合,以将头部芯部和头部支撑件部分地连接在一起。 在移除固定夹具并且将玻璃料安装在头部支撑件上以覆盖头部芯部上方的狭缝之后,将该组件装载到加热炉中以熔合玻璃料,从而永久地将头部芯部和 头支撑在一起

    • A polygon mirror includes a polygon base having a plurality of attaching surfaces, a plurality of base plates each of which is fixed to each of the attaching surfaces of the base and has a reflecting surface for reflecting a laser beam, a plurality of total reflection mirrors each of which is fixed onto each of the base plates, and a reflecting direction adjusting mechanism. The reflecting direction adjusting mechanism connects the base to the base plate for the adjustment of a direction along which the laser beam is reflected by the reflecting surface of the total reflection mirror with respect to the attaching surface of the base.

    • Piezo-electric oscillators are widely used in reference clocks for various apparatus. Prior to use, the oscillation frequency of the piezo-electric oscillators is generally finely adjusted. For this purpose, a frequency fine-adjusting apparatus includes a laser beam generator for emitting a laser beam having a wavelength of 2 .mu.m or less, a target material having a metallic layer, a set of rollers for feeding the target material in the condition in which the metallic layer confronts the main electrode of the piezo-electric oscillator and is spaced a predetermined length from the main electrode, and an optical system for applying the laser beam to the metallic layer. When the laser beam is applied to the metallic layer, part of the metallic layer is vaporized and adheres to the surface of the main electrode, thereby finely adjusting an oscillation frequency of the piezo-electric oscillator.
    • 压电振荡器广泛用于各种设备的参考时钟。 在使用之前,压电振荡器的振荡频率通常被精细调节。 为此,频率调节装置包括用于发射波长为2μm以下的激光的激光束发生器,具有金属层的目标材料,用于在条件下供给目标材料的一组辊 其中金属层面对压电振荡器的主电极并且与主电极间隔预定长度,以及用于将激光束施加到金属层的光学系统。 当将激光束施加到金属层时,金属层的一部分被蒸发并粘附到主电极的表面,从而微调压电振荡器的振荡频率。
