摘要： A zoom lens is provided, in which a fixed first lens group having a positive refracting power, a second lens group having a negative refracting power and which realizes a variable magnification, a fixed third lens group having a positive refracting power and a fourth lens group having a positive refracting power which compensates fluctuation of an image surface caused by the variable magnification and which focuses an image are sequentially provided from an object side. In this zoom lens, the third lens group is composed of two separate lenses of a positive lens (31) and a negative lens (32). At least one surface of the positive lens (31) is formed as an aspherical surface and a surface of the negative lens (32) opposing the image surface side is concaved to the image surface side. Thus, the zoom lens of this invention can be miniaturized and reduced in weight without deteriorating the characteristics such that a variable magnification is large and that an F number is small.

摘要： A covered balloon for use as a toy or in a display, which includes a cover formed of a plastic film and a rubber balloon inside the cover. More specifically, the cover is formed of two superposed sheets of substantially gas impervious plastic film whose peripheral edges are welded to form a seam. In a one embodiment, the cover and the rubber balloon each have a nozzle and the rubber balloon is inflated so as to fill the entire space within the cover and eliminate any wrinkles in the cover and adhere to an interior surface of said cover with the nozzle of the rubber balloon protruding from the cover through the nozzle of the cover. A welding flap formed along the seam when the cover is formed by welding together the plastic sheets, may be substantially reduced in size by cutting the flap along the seam. The cover may be formed of a transparent film such as a film of ethylene-vinyl alcohol copolymers so that the rubber balloon inside is visible. According to another embodiment, the rubber balloon fills only a portion of the space within the cover, the remainder being inflated with a gas.

摘要： Disclosed is an elastic absorbent which comprises a substantially homogeneous mixture of pulverized cellulose pulp and staple fibers of a split yarn obtained by splitting a tape-form oriented laminate comprising at least one layer of a synthetic resin having a high melting point and at least one layer of a synthetic resin having a low melting point, in which the layer of the synthetic resin having a low melting point is at least partially exposed to the surface. Another elastic absorbent comprises an intermediate layer of a powdery polymeric water-absorbing agent, which is interposed between upper and lower layers, each of the upper and lower layers comprising a substantially homogeneous mixture of pulverized cellulose pulp and staple fibers of the same split yarn as mentioned above. At the crossing points of the staple fibers, of the split yarn, the synthetic resin having a low melting point is at least partially fusion-bonded and the staple fibers of the split yarn are connected to one another in the state where the cellulose pulp is partially enclosed therein.

摘要： A process for dehydrating water-containing organic solid material which comprises steps of introducing the material into a pressure vessel, applying saturated steam to said vessel to heat the material so that water in the material be removed and mixed with condensate of the steam to be exhausted from the vessel as a waste water. The process is characterized by a step of charging material of relatively large particle size at a bottom portion of the vessel and of relatively small particle size on the material of large particle size. The process makes it possible to dehydrate relatively fine particles of material by utilizing liquid form dehydration phenomemon.
