Title: Optical modulator
Inventor: KATO HAJIME
IPC: G02F1/035
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To remove a dip that optical modulation characteristics of the optical modulator have by providing an air layer below a tapered part and a feed part of a progressive wave electrode and at their peripheries across an optical substrate. SOLUTION: A groove part 24 provided for a metallic housing 23 is a part which becomes the air layer when a substrate (optical substrate) 18 is fixed to the metallic housing 23. This groove part 24 is provided below the tapered part and feed part of the progressive wave electrode 16 provided on the substrate (optical substrate) 18 when the substrate (optical substrate) 18 is fixed to the metallic housing 23. When the air layer is thus provided, the gap between the progressive wave electrode 16 and metal housing 23 becomes wide, so almost all of lines of electric force in the substrate (optical substrate) 18 travel from the progressive wave electrode 16 to a ground electrode 17. At this time, the distance from the progressive wave electrode 16 to the metallic housing 23 needs to be made longer than the distance from the progressive wave electrode 16 to the ground electrode 17.

Filed: 1985-02-01
Abstract: PURPOSE:To prevent the meandering of strip and to obtain a stable rolling condition by increasing a gap between adjoining driving rolls at the side on which a thrust is acting and decreasing the gap at its opposite side. CONSTITUTION:A floating roll 13 is fixedly supported inthe axial direction through thrust bearings 17 and load cells 18, and a thrust in the axial direction is detected by the cells 18 and load detecting units 19, to transmit it to a host computing unit 20. The unit 20 actuates rolling reduction units 22 by rolling- reduction control units 21, to increase a gap between both contacting rolls 11, 12 at the side on which the thrust is acting and decrease the gap at its opposite side till the thrust reaches zero. In this way, the roll gap between both rolls 11, 12 is adjusted at both sides to rotate the axis of roll 13 with respect to a pass line. Accordingly, the meandering and lateral movement of a strip 15 is prevented by eliminating the thrust acting in the axial direction of roll 13.

Title: Apparatus for anchoring tensile material of anchor, especially, lock anchor
Inventor: TOOMASU HERUPUSUTO
IPC: E21D21/00
Filed: 1986-01-30
Abstract: An anchoring apparatus for insertion into a borehole in a rock stratum for supporting the rock surface or wall, such as in a rock tunnel or rock excavation, includes a tension member in the form of an axially elongated steel rod with force transmission ribs on its outer surface and an anchoring element, such an anchoring nut, engageable with the rod. The anchoring element has an inside surface with inwardly extending projections and the adjacent flanks on the projections form grooves within which the force transmission ribs engage. The anchoring element is formed of a higher strength material than the rod. When a predetermined axially extending tension force acting on the rod is exceeded, relative movement takes place between the anchoring element and the rod. The flanks on the projections on the anchoring element in contact with the ribs on the rod shear off a portion of the ribs contacted. Accordingly, while the predetermined force is exceeded, the shearing action proceeds and affords a sliding anchoring effect between the rod and the anchoring element.
