Abstract: PURPOSE:To suppress the amplification of an error in the amount of travel of each point in normalization by using a smooth accumulation function. CONSTITUTION:Characteristic quantities f(x) in the (x) positive direction and the (x) negative direction of a remarked point is found by using equation I or a function applying correspondingly to it on a character image based on a distance (¦xe-x¦) between the remarked point (x,y) and character contour points neighboring in the (x) positive direction and the (x) negative direction, and the sum of them is set as the (x) directional characteristic quantity value of the remarked point, and the characteristic quantities f(y) in the (y) positive direction and the (y) negative direction of the remarked point is found by using equation II or the function applying correspondingly to it based on a distance (¦ye-y¦) between the remarked point and the character contour points neighboring in the (y) positive direction and the (y) negative direction of the remarked point, and the sum of them is set as the (y) directional characteristic quantity value of the remarked point, thereby, nonuniformity in the distribution of obtained (x) directional and (y) directional characteristic quantity values can be corrected. Where, (a), (b), and (c) are constants in equations I and II.

Title: Friction material for vehicle
Inventor: YODA KIYOSHI
IPC: F16D69/00
Filed: 1995-06-14
Abstract: PURPOSE: To reduce the time required for smoothing the surface of a friction material formed with a resin mold without increasing the kinds of raw materials or production steps by forming, on the surface of the friction material, a surface layer having a resin content lower than that of the friction material. CONSTITUTION: A friction material 12 obtd. by preforming a mixture contg. a phenol resin, various kinds of fibers, an org. agent, a metal, an abrasive, a lubricant, etc., is placed on a backing plate 11. A surface layer 13 having a resin content of 10-50wt.% of that of the friction material 12 and preformed independently of the friction material 12 is placed on the surface of the friction material 12 and thermally press molded together with the friction material 12 to be integrally fixed to the plate 11. Thus the surface layer 13 can be formed on the surface of the friction material 12 without increasing the kinds of materials or production steps.  Moreover, since the surface layer 13 is quickly worn away, the friction area becomes large and a desired friction force is obtd. from the early stage of the use, enabling a large decrease in the time required for smoothing the surface in comparison with a conventional friction material.

Title: Magnified display device
Inventor: YAMAOKA MIKI
IPC: G09F11/26
Filed: 1989-06-12
Abstract: PURPOSE:To prevent a film from being damaged by the heat of a light source by enclosing the heat generated by the light source on the light source side with the aid of the plural sheets of heat resistance glass and promoting the heat dissipation of the heat resistance glass with the aid of cooling wind, on the other hand. CONSTITUTION:Since the heat generated by the light source 214 during the display of an image is absorbed by two steps by two heat ray absorbing filters 215, it is hardly transmitted to the film 300 existing at a film passing part. On the other hand, even when the filters 215 are heated by the heat generated by the light source 214, the heat absorbed by the filters 215 is efficiently dissipated by actuating a fan 216 during the display of the image. By efficiently diffusing the heat absorbed by the filters 215 in such a way, the filters 215 maintain sufficient heat absorbing ability and it is suppressed that the heat is transmitted to the film 300.
