CONSTITUTION:The 1st group consists of a negative meniscus lens which as its convex surface on an object side and a positive lens which has its large- curvature convex surface on the object side in order from the object side. The 2nd group consists of a negative meniscus lens which has its convex surface on the object side, a biconcave lens, and a biconvex lens. The 3rd group consists of a biconvex lens, a biconcave lens, a positive lens with its large-curvature convex surface on the image side, and a biconvex lens. The inequalities I-IV hold for the focal length fi of an i-th group, the mean value N2N of the refractive index of the negative lens in the 2nd group, and the gap ds between the biconcave lens and biconvex in the 2nd group.

Title: Protective film
Inventor: YAMANAKA MINORU
IPC: B32B18/00
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a protective film capable of easily imparting self-cleaning properties by bonding the protective film to a member to keep them over a long period of time. SOLUTION: A siliceous ceramics layer 2 comprising polysilazane or a modified matter thereof is formed on a base material 1 and a photocatalyst- containing layer 3 is formed on the outer surface of the ceramics layer 2.

This thermosensitive layer 14 is a white color layer consisting of a mixture of a vinyl hloride - vinyl acetate copolymer and a fatty derivative. When the detecting card is fed to a conveor system, the part brought into contact with a burr occurring spot of the thermosensitive layer 14 is varied into transparency by dint of pressure, so that any burr in the conveyor system is easily detectable. Since the thermositive layer 14 is reversibly varied into a white state by heating, the card is reusuable for burr detection.

Title: Stepless speed changer with belt
Inventor: AKUTAGAWA HITOSHI
IPC: F16H37/02
Filed: 1986-08-26
Abstract: PURPOSE:To facilitate machining and make the construction in small size by furnishing an engaging/disengaging means which is to mesh at least one of the gears in a reverse gear train with another gear with possibility of engagement/disengagement. CONSTITUTION:At the time of advancing, an advance clutch 36 is in connection while a backward motion clutch 52 is off, and the torque on an input shaft 26 is transmitted to output shaft 30 through a belt 34. Here No.1 idler gear 58 in a reverse gear train 48 is held in separated position where no meshing is made with driving gear 54. Accordingly in said backward motion clutch 52, a receipt plate 52b in connection with the output shaft 30 will solely rotate, and the relative revolving speed between the driving plate 52a and receipt plate 52b should be suppressed low. Because the advancing clutch 36 and backward motion clutch 52 are mounted on the input shaft 26 and output shaft 30, respectively, the span between the two clutches 36, 52 can be set short. This eliminates necessity for too high machining accuracy and enables constructing the device in small size.
