Filed: 1985-01-29
Abstract: PURPOSE:To realize an IC of higher performance with its charactetistics improved by a method wherein the entire surface of an oxide film is covered by an nitride film and an electrode. CONSTITUTION:An oxide film 2 is formed on the entire surface of an Si substrate 1, to be followed by the formation of a nitride film 3. A desired pattern of a photoresist 4 is provided by application on the nitride film 3, and the photoresist 4 serves as a mask in a process wherein the nitride film 3 is subjected to plasma etching or the like for provision of an opening 5. The photoresist 4 is then removed, another photoresist 6 is provided application, patterning is accomplished to affect the opening 5 well into its depth. Another opening 7 is formed inside the opening 5 with the patterned photoresist 6 serving as a mask, for the provision of an electrode contact window 8. The photoresist 6 is removed, and then an electrode 9 is built in the electrode contact window 8. This results in a semiconductor device A, with its entirety covered by the electrode 9 and nitride film 3, which does not allow any portion of the oxide film 2 to be exposed on the surface.

Title: Round and curved waveguide device
Inventor: NAKASHIMA NOBUO
IPC: H01P1/16
Filed: 1981-02-04
Abstract: PURPOSE:To obtain the good separating properties between two orthogonal polarized waves over a wide range, by setting the long/short axis ratio of the cross section and the angle of rotation of an elliptical waveguide at a prescribed value respectively. CONSTITUTION:For an elliptical waveguide 6, the long/short axis ratio of the cross section is previously set so as to produce a reverse turning elliptical polarized wave corresponding to the elliptical polarized wave which is produced from a round and curved waveguide 1. At the same time, the angle of rotation is set by the rotation mechanism in accordance with the inclination of the long/ short axis of the waveguide 1. Such waveguide 1 has a large diameter and can be applied even in case when the elliptical polarized wave properties are defined by the deviation of the tube diameter as well as a higher mode wave caused by the curve.

Title: Phasing device
Inventor: OBO RYOSAKU
IPC: G05B23/02
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To obtain a phasing device capable of automatically performing execution phase management for data collection processing. SOLUTION: A state monitoring means 15 monitor whether or not a data collection request is newly generated, when the data collection request is newly generated, an evaluating means 16 newly evaluates the data collection request, retrieves a phase where the total number of phases is the smallest and decides whether or not the phase plurally exists. When the plural phases exist, the setting of an initial value is made unnecessary by making the phase being the closest to a designated cycle among them an initial value phase and making the phase the initial value phase when the phase is single. It is also possible to maintain an optimized phase state in the meaning that loads are not concentrated even when a new data collection request is generated from an application.

Title: Magneto-optical disk and magneto-optical disk device
Inventor: NAGARA TORU
IPC: G11B11/105
Filed: 1995-02-02
Abstract: PURPOSE: To avoide the adverse effect caused by dust, to facilitate the assembling work and to reduce the height of a magneto-optical disk device. CONSTITUTION: One surface of a disk substrate 2 of the magneto-optical disk 1 is coated with a magneto-optical recording film 3 and the other surface is coated with a reflective film 4. An optical pickup 10A and a magnetic head 12 of the magneto-optical disk device 10 are placed on the film 3 side of the disk 1. A laser beam passes the film 3 and the substrate 2, is reflected by the film 4 and focused on the inner surface side of the film 3. Since the diameter of the beam when passing the film 3 is larger than the spot diameter of the focus, the adverse effect caused by dust is reduced. Moreover, since no alignment is required for the pickup 10A and the head 12, the assembling work is made easy. Furthermore, since no gap is required between the pickup 10A and the head 12, the height of the device is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a compact substrate conveyor in which occurrence of a cross-contamination is low, and reliability in substrate support is high. SOLUTION: A substrate guide 258b is formed higher than a substrate guide 258a. When a unprocessed substrate W is conveyed, a hand element 253b is closed, so that the substrate guide 258b is brought into contact with a substrate W for support, and convertly, when a processed substrate W is conveyed, the hand element 253b is opened, so that the substrate guide 258b is positioned outwatdly of an outer periphery of the substrate W and the substrate guide 258a is brought into contact with the substrate W for support. Thus, cross- contamination is suppressed, and further as the hand element 253b is only opened and closed substantially in a horizontal direction, even if air leakage occurs in an air cylinder for driving them, the substrate W does not drop so much.
