Abstract: PURPOSE:To simplify the mechanism of a device for reading out optically the information recorded on a disc by a laser, etc. and a camera provided with an auto-focusing mechanism by using a material which allows transmission of light and has a piezoelectric characteristic as a lens and providing electrodes thereto. CONSTITUTION:A transparent piezoelectric material 1 which allows transmission of light is worked to, for example, a convex lens and is stuck with a pair of transparent electrodes 2A, 2B alowing transmission of light on the surfaces thereof. A rock crystal of single crystal is used for the transparent material 1 and tin oxide or the like is used for the transparent electrodes 2A, 2B. When a DC voltage is applied between the upper and lower electrodes 2A and 2B, the curvature of the material 1 is changed by the strain generated in the part of said material and the focal length of the lens changes accordingly. The information recorded on the disc is optically read out by a laser or the like so that the focus is always correctly formed on the disc.

IPC: G03B27/62
Filed: 1986-01-29
Abstract: PURPOSE:To form the binding margin of a top-side copy image and the binding margin of a reverse-side copy image at end parts of the same side by forming the 1st surface image of a both-surface original in normal mode and displacing the 2nd surface image by the binding margin when a both-surface/one-surface mode and a margin adjustment mode are selected. CONSTITUTION:It is decided whether or not the margin adjustment mode is set under margin magnification variation control and when so, a code of copy mode is decided. When the code is 0, normal copying operation is performed as it is. When the code is 1, a top surface copy display is decided and when a copy needs to be taken on the top side of a copying form, the copy is taken normally. When the top-surface copy display is off, an image is copied while shifted by the margin. Consequently, when a both-surface original is copied on different copying forms, the 1st and the 2nd sheets are prevented from having margins on the opposite sides.

Title: Eddy current flaw detection equipment for metal cylinder
Inventor: HARA AKIMITSU
IPC: G01N27/82
Filed: 1985-01-30
Abstract: PURPOSE:To enable the detection of flaws on a partially deformed cylinder, by dividing a sensor and a guidance unit into sector segments so as to let abnormally deviated radius section of a sample pass. CONSTITUTION:A guidance unit and a sensor are divided into four sets (equivalent to the number of sensors) of hollow segments 41a-41d each with a sector-shaped section and roller conveyors 42a-42d are set to guide a sample T at a specified speed. Moreover, fluid positioners 43a-43d are set to move the segment involved outward when the surface having an abnormally deviated radius of the sample T passes through the equipment. When the deviated radius of the sample T is smaller than an allowable value, a flaw detector detects flaws with the continued rotation thereof though the value is below the reference. Only when the portion with the abnormally deviated radius exceeding the allowable value passes through the flaw detector, the flaw detector stops the rotation and makes the effective sectional area of the hollow part for passing the sample T thereof so larger to allow the passage thereof. Then, the portion having required no flaw detection is made clear by marking the cylinder surface corresponding to the abnormally deviated radius or memorizing the portion into a controller.
