Title: Endoscope
Inventor: NISHIOKA KIMIHIKO
IPC: G02B23/26
Filed: 1988-04-06
Abstract: PURPOSE:To enable the removal of dot patterns and focus adjustment with simple constitution by constituting a 1st optical element for moving an imaging position in such a manner that said element can be moved and oscillated in an optical axis direction and providing the 2nd optical element which can correct the deviation of the image appearing on an eyepiece side end face in the direction orthogonal with the optical axis direction. CONSTITUTION:A lens 11 and 1st prism 12 as the 1st optical element are moved in the optical axis direction by a DC voltage impressed to a driving means 15 from a DC power supply 17 and is oscillated around the prescribed position by the AC voltage impressed to the driving means 15. A prism 24 as the 2nd optical element is disposed to the rear end side of the prism 23 and the refractive index of the prism 24 is periodically changed to oscillate the optical path in the direction orthogonal with the optical axis direction when an AC voltage is impressed to the driving means. The deviation of the image by the oscillation of the prism 12 is corrected by the prism 24 in such a manner. The removal of the dot patterns and the focus adjustment are thereby enabled with the simple constitution.

IPC: E04B1/58
Filed: 1993-04-13
Abstract: PURPOSE:To improve workability by laminating an inner joining member inside a steel pipe concrete column and an outer joining member outside the column, and attaching thereto a split tee with a beam flange welded. CONSTITUTION:An outer joining member 3 is temporarily installed outside a part of a circular steel pipe column 1 where the flange of the beam 2 is to be welded, and a split tee having the welded flange of the beam 2 is overlapped on the outer joining member 3. In addition, an inner joining member 5 is overlapped from the inside of the circular steel pipe column 1, and the outer joining member 3 is sandwichedly fastened by a high-strength bolt 6 to join the circular steel pipe column 1 with the beam 2. Thus, since welding for the joined part is minimized, and only drilling is utilized for manufacture, workability can be improved.

Filed: 1983-05-17
Abstract: PURPOSE:To make the width of a locking groove uniform and to obtain a desired shape by providing preliminarily the locking groove to a flat plate blank material in a way as to offset the working deformation in the stage of subjecting the material to bending with a tapered shape. CONSTITUTION:A locking groove 15' is formed in a flat plate blank material cut to a prescribed size. The width of the groove is the same as tht width W of the groove when a lock collar is finished. Said groove is formed to such a tapered shape at which the groove width decreases from the part around the center toward the surface to be brought on the outside circumferential side of a cylindrical lock collar to W1 until said width attains W1 on the outside circumferential surface and that the groove width increases from the part around the center toward the surface to be brought on the inside circumferential side until said width attains W2 on the inside circumferential side in the case of bending said groove. A compressive deformation is acted in the part where the groove width decreases from the part around the center toward the outside circumferential side and a tensile deformation is acted on the part where the groov width increases from the part around the center toward the inside circumferential side by the working deformation when the locking groove 15' formed in such a way is bent to the flat plate blank material. The locking groove has the uniform width W when the lock collar 14 is completed.

Filed: 1985-04-22
Abstract: PURPOSE:To improve cleaning efficiency, to prevent a toner filming phenomenon and to obtain sharp copy images by employing a polygonal cleaning member which has a rotating shaft as a cleaning part. CONSTITUTION:A photosensitive body 1 rotates as shown by an arrow and the edge 5a of a cleaning blade is rubbed against residual toner on the photosensitive body 1 to remove the toner.

Title: Equipment for refining rolling stock
Inventor: YAMASHITA HARUTOSHI
IPC: B21C47/00
Filed: 1994-04-26
Abstract: PURPOSE:To enable stable supply of rolling stocks with satisfactory quality by providing plural deflector rolls that are replaceable into a transporting pass line in accordance with the surface condition of a rolling stock. CONSTITUTION:The equipment is so constructed that an oil coater 2, at least a set of pinch rolls, shear S and deflector roll 5 are successively arranged towards a reel 6 for coiling a rolled stock 1. Since the outer diameter of a coil changes every minute during the coiling of a rolled stock, the deflector roll 5 is arranged before the take-up reel in order to constantly stabilize the level of a transporting pass line. After the rolled stock 1 is cut off by the shear S, the rolling stock is not present between the shear and the take-up reel, consequently facilitating the exchange of the deflector roll 5. In the case where sticking of a coating oil is to be desirously avoided, the replacement of the deflector roll 5 has only to be performed, which not only dispenses with addition of extra processes but eliminates lowering of quality and also improves productivity.
