摘要： A plasma processing system is comprised of a reaction vessel in which are provided a parallel high frequency electrode and ground electrode. The ground electrode is fixed at a ground potential portion, that is, a flange, by a conductive support column. A connection portion from the ground electrode to the ground potential portion, for example, the portions other than the surface of the ground electrode and the surface of the support column etc. are covered by an insulator serving as a high frequency power propagator while the surface of the insulator is covered completely by a conductive member except at the portion for introducing the high frequency power. In this plasma processing system, it is possible to reliably prevent undesirable discharge from occurring at the rear surface of the ground electrode when processing a substrate mounted on the ground electrode to deposit a film using a high frequency power in the VHF band.

摘要： Because of its composition that is liable to be crystallized and therefore has a low strength, a conventional sealing glass for magnetic head has a problem in that in a manufacturing process for manufacturing a magnetic head having a narrow track width and a short gap length corresponding to the high-density recording in recent years with high accuracy, cracks are liable to be developed in a sealing glass portion by an impact caused in cutting and grinding a head chip. By using glass having a composition of 13 to 17 wt % SiO2, 5 to 6.8 wt % B2O3, 70 to 77 wt % PbO, 0.1 to 5 wt % of at least one of Al2O3 and ZnO, and 0.1 to 3 wt % of at least one of Na2O and K2O as a front sealing glass and using glass having a composition of 3 to 9 wt % SiO2, 11 to 17 wt % B2O3, 66 to 77 wt % PbO, and 3 to 15 wt % of at least one of Al2O3 and ZnO as a back sealing glass, a high-performance magnetic head having a high strength can be provided in high yields.
摘要翻译：由于其组成易于结晶并因此具有低强度，所以传统的磁头密封玻璃的问题在于，在制造具有窄轨道宽度和短间隙长度的磁头的制造过程中近年来高精度的高密度记录，由于在芯片的切割和研磨中产生的冲击，密封玻璃部分容易产生裂纹。通过使用组成为13〜17重量％SiO 2，5〜6.8重量％B 2 O 3，70〜77重量％PbO，0.1〜5重量％的Al 2 O 3和ZnO中的至少一种，和0.1〜3重量％作为前密封玻璃的Na 2 O和K 2 O中的至少一种，使用组成为3〜9重量％SiO 2，11〜17重量％B 2 O 3，66〜77重量％PbO和3〜15重量％ Al 2 O 3和ZnO作为后密封玻璃，可以高产率提供高强度的高性能磁头。

摘要： A light intensity distribution converting device is formed by a transparent body having a first curved surface, a second curved surface, and an outer circumferential surface extending between the first and second curved surfaces. One of first and second surfaces has a concave surface configuration and the other has a convex surface configuration. Diverging light is made incident to the first curved surface, for example. The light intensity distribution of light made incident to the body from first curved surface is different from that of light emerging the body from the second curved surface, due to refractions at the first and second curved surfaces. The light intensity distribution converting device can be used as a collimator lens or an objective lens in an optical data storing apparatus.

摘要： The present invention relates to an information reading and writing device for an optical signal, and the optical system is simplified by using a diffraction optical element. A semiconductor laser is used as a light source. There is provided an image formation lens for condensing a beam of light and forming an image on an optical disk medium. In an optical path between the semiconductor laser and the image formation lens, there is provided a hologram having a function of the hologram region diffraction optical element for detecting a tracking error signal of the medium and a focus detection error signal. Two optical detecting elements 24a, 24b for detecting the focus error respectively have two divided regions. Under the condition that the medium is in focus, beams of light diffracted in the two hologram regions 23a, 23b for detecting the focus become the convergent beams which are most converged on a dividing line of the respective optical detecting element and in the direction of the optical axis. The beams of light on two optical detecting elements are in a condition of substantial point symmetry with respect to the central axis of the hologram.

摘要： An optical pickup irradiates a record surface of an optical storage medium with light and receives the light reflected by the record surface. The reflected light includes a data signal light corresponding to data recorded on the optical storage medium and other light. The optical pickup comprises a light source, a data photo detector, another photo detector, a base, a beam splitter, an introductive optical element, and a lens. The light source emits the light to the record surface. The data photo detector receives the data signal light. The another photo detector receives the other light. On the base, the light source, the data photo detector and the another photo detector are arranged. The beam splitter transmits the light from the light source and separates the reflected light from the optical record medium into the data signal light and the other light. The introductive optical element introduces the data signal light to the data photo detector and the other light to the another photo detector. The lens condenses the light from the light source transmitted through the beam splitter on the optical record medium and introduces the reflected light from the optical record medium to the beam splitter.
