Title: Automatic deburring device for steel plate end surface
Inventor: MAEDA YOICHI
IPC: B23D79/00
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To smoothly perform deburring work of a steel plate end surface by providing a polishing disk rotating mechanism, a traveling mechanism to make a polishing disk travel over the whole width in parallel to the steel plate end surface, a carrying direction copying mechanism, a polishing disk raising-lowering mechanism and an air balance circuit to adjust press contact force. SOLUTION: A polishing disk 6 is rotated while lowering the polishing disk 6 at high speed under high pressure by an air cylinder, and after detecting that it is brought into press contact with a steel plate 1 end surface, press contact force to a burr part is switched to low pressure, and a burr is removed while traveling along the steel plate 1 end surface. At this time, even if the steel plate 1 end surface deflects in the vertical direction since a shape of a steel plate 1 is bad, at traveling time, the polishing disk 6 to always rotate by a vertical direction copying mechanism part is brought into press contact with the steel plate 1 end surface so as to be lightly pushed at its discretion, and follows the steel plate 1 end surface by always keeping a proper grinding quantity.  Even if a position is dislocated since stopping accuracy of the steel plate 1 is bad, it can reliably follow the steel plate 1 end surface by always detecting a relative distance between the polishing disk and the steel plate 1 end surface by a steel plate end surface detecting sensor.

Title: Liquid crystal element
Inventor: SATO SUSUMU
IPC: G02B3/10
Filed: 1988-02-10
Abstract: PURPOSE:To make the axially-symmetrical molecule orienting characteristic of a liquid crystal element utilizable by orienting liquid crystal molecules in such a way that on one substrate of the liquid cell the molecules are oriented with their major axes arranged in one direction and on the other substrate the molecules are oriented with their major axes arranged concentrically or radially. CONSTITUTION:After performing treatment so that liquid crystal molecules can be oriented homogeneously in one direction on the substrate 1 on the incident side and molecules can be oriented concentrically on the substrate 2 on the other side, liquid crystal 4 is enclosed into the liquid crystal cell formed of the base plates 1 and 2 with a spacer in between. When a linearly polarizing plate 5 is placed on the incident side, with the polarizing direction being made coincident with the oriented direction of the liquid crystal molecules, the polarizing direction of the light passed through the liquid crystal cell becomes the oriented direction of the molecules on the light emitting side, namely, concentric. On the other hand, when the polarizing direction of the polarizing plate 5 is turned to the direction perpendicular to the major-axis direction of the homogeneously-oriented liquid crystal molecules on the incident-side base plate 1, a radially polarized output is obtained. Therefore, an axially- symmetrical (centrally-symmetrical), such as concentric, radial, etc., polarizing characteristic can be obtained with a simple constitution.
