Abstract: Calcium phosphate glass-ceramics of high strength and toughness is disclosed. These materials are excellent for artificial dental or bone materials. The strength and toughness of these materials are improved substantially in comparison with conventionally used calcium phosphate glass-ceramics by adding rare earth oxide in them. For dental materials, good aesthetic appearance to natural teeth is also obtained by adding one type, or two or more types of compounds selected from oxides of iron, manganese, cerium, titanium, nickel, zinc, cobalt, tungsten, chromium, and vanadium as color component. Also, if necessary, Al.sub.2 O.sub.3 and/or SiO.sub.2 is contained as coloring assistant agent in that composite. Moreover it is possible to adjust the color tone of each individual's teeth. The rare earth oxide, coloring component, and coloring assistant agent added are incorporated in crystals of calcium phosphate. Consequently, they cause no elution during use.

Abstract: Dental materials using calcium phosphate glass-ceramics and having the color tone with high approximation to that of natural teeth. In those dental materials, calcium phosphate composite, nickel oxide and one or more other type of compounds selected from oxides of iron, manganese, cerium, titanium and tungsten, are contained as coloring component. Also, if necessary, Al.sub.2 O.sub.3 and/or SiO.sub.2 is contained as a color assisting agent in that composite. The calcium phosphate glass-ceramic according to this invention consists of the same components as that of natural teeth. Besides, it is possible to adjust the color tone delicately to match with the color tone of each individual`s teeth. Moreover, the coloring components are incorporated in crystals of calcium phosphate. Consequently, they cause no elution during use and are therefore ideal as dental material.

Abstract: The disclosure is related to a method for removing crude oil sludge, which is convenient for removing sludge while the crude oil is transported. The method for removing crude oil sludge from crude oil includes the steps of:(a) classifying grains of sludge into coarse grains and small grains;(b) settling the sludge in the crude oil discharged from the classification step to separate the coarse grains from the crude oil;(c) sending the crude oil which is the supernatant constituent in the settling step to a filter in order to separate the remaining sludge in the crude oil; and(d) introducing a part of the above crude oil to a reverse washing liquid inlet of the filter, in order to wash reversely the filter medium of the above filter.

Abstract: A lens barrel is capable of selectively establishing a power focus mode in which an internally housed motor moves a taking lens to a position of any desired focal length, a single "auto-focus" mode in which the taking lens is moved to a position which is in focus to a stationary object being photographed, and a sequence "auto-focus" mode in which the taking lens is continuously moved in focus to a moving object being photographed. Any one of these modes is suitably selected by a mode changing switch. A movement of the taking lens in each mode is initiated by an operating member.
