Title: Ftheta lens system of optical scanner
Inventor: ITABASHI AKIHISA
IPC: G02B26/10
Filed: 1989-02-27
Abstract: PURPOSE:To correct the curvature of field in the lens system in a main scanning direction and a subscanning direction sufficiently and to prevent the surface tilt of a rotary polygon mirror by composing the lens system of two lens elements in two groups and meeting specific requirements as to the composite focal length and the radii of curvature of 1st, 3rd, and 4th surfaces. CONSTITUTION:This lens system has a function which puts the reflection position of the rotary polygon mirror and a scanned surface in geometric-optically almost conjugate relation in the subscanning direction and an ftheta function in the main scanning direction. This lens system consists of two elements in two groups; and the 1st surface counted from the side of the rotary polygon mirror is a concave saddle-shaped toric surface, the 2nd and 3rd surfaces are concave cylinder surfaces having refracting power only in a deflection-directionally orthogonal plane, and the 4th surface is a convex toric surface having large curvature in the deflection-directionally orthogonal plane. Then an inequality I holds for the composite focal length fs in the deflection- directionally orthogonal plane and the radii r1', r3', and r4' of curvature of the 1st, 3rd, and 4th surfaces in the deflection-directionally orthogonal plane. Consequently, the surface tilt of the rotary polygon mirror is corrected excellently, the curvature of field is compensated in the main-scanning and subscanning directions to realize optical scanning.

Abstract: PROBLEM TO BE SOLVED: To obtain a synthesis inhibitor capable of effectively improving and curing a physiological state of a patient having an autoimmune disease such as type I diabetes or rheumatoid arthritis by using a readily available specific extract. SOLUTION: This synthesis inhibitor uses a malt extract as an active component of a synthesis inhibitor of heat-shock protein having 57-68kDa molecular weight. As the malt extract, e.g. directly an article on the market, or preferably an article removed a low molecular weight fraction from the malt extract on the market by a dialysis, etc., can be used. Otherwise, an article obtained by saccharifying the malt, filtering, extracting the resultant residue with water, a hydrophilic solvent or their mixed solution and removing a low molecular weight compound fraction having <=1×10<4> molecular weight may be used.  In this case, the extraction is performed under an alkaline condition, a precipitated substance is removed by neutralizing the resultant extract solution and a low molecular weight fraction is removed from the supernatant, then the resultant substance is more preferably used.

Filed: 1995-03-07
Abstract: PURPOSE: To improve rigidity of a ball screw with good efficiency by applying pressure on a ball which is passed a transfer tube by a push-pressing means. CONSTITUTION: A push-press means 10 consists of a spring 11 for applying pressure on a ball which is passed a transfer tube 8. The tube 8 is installed on a nut 1 in such a way that the end part of the tube 8 is inserted in a transfer tube inserting hole 1b till a boundary between a ball passing hole 1a and the hole 1b. The ball 7 is pushed in the ball circulating passage in the tube 8 and a spiral passage 6 while having pressurization. As a result, the ball 7 is pushed against the walls of a screw groove 3 and 5 in the spiral passage 6 so as to bury a clearance between the screw groove 3 of the nut 1 and the screw groove 5 of a screw shaft 4. A slight lead error of the screw shaft 4 does not affect accuracy or require the selection of a ball diameter, for example.
