摘要： The burden of developing a complex bridge block imposed on the IP reuser is reduced by introducing a system clock into the IP. The IP composed of a functional circuit of this invention and its synchronizing circuit takes in the system clock by integrating the synchronizing circuit taking in the system clock with the IP functional circuit into the IP in reusing the IP complying with the standard in the development of an LSI with a built-in IP and its derivatives. This enables the reuser to incorporate the IP into the LSI via a simple bridge block, taking into account only the system clock for driving the system bus, which reduces the burden of handling the IP and increases the reusability of the IP.

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： 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： A light-beam scanning apparatus including a rotatable hologram and a fixed plate, which are provided with diffraction gratings to minimize: either a sum total of values obtained by weighting where a square of an optical path length difference between an optical path of a light flux measured along a principal axis of a light beam incident on and diffracted by a diffraction grating of a rotatable hologram, and incident on and diffracted by a diffraction grating of a fixed plate so as to conduct a scanning and converging on a scanning point on an image formation surface, and an optical path of a light flux measured along a marginal ray distanced from the principal axis; or an absolute value of the optical path difference thereof. Another sum total obtained by weighting requiring minimization is: a square of a sum obtained by adding: an amount of displacement of a light beam convergent on a scanning point on the image formation surface, which displacement is measured along the marginal ray distanced from the principal axis of an incident reconstructing light flux with respect to the principal axis of a phase of the diffraction grating of the rotatable hologram to an amount of displacement of the same light, the displacement measured with respect to the principal axis of a phase recorded on the diffraction grating when the light flux is incident on the fixed plate; or by weighting an absolute value of the sum over every scanning position of the formation surface.
