    • A particulate trap for use with a diesel engine is high in particulate trapping capacity and regenerating capacity and low in pressure drop, and yet is compact and inexpensive. This trap has a filter element made up of a plurality of tapered filter members formed from a fabric of heat-resistant metal fibers. The filter members have different diameters from each other and are nested concentrically one inside the other so that the adjacent filter members are positioned inversely. Each filter member is connected at its large-diameter end to the small-diameter end of the immediately outer filter member to alternately close the exhaust inlet and outlet ends of the gaps between the adjacent filter members. The filter element thus formed is mounted in a metal case provided in an exhaust line and used as a particulate trap. With this arrangement, it is possible to increase the particulate trapping area of the filter and the exhaust inlet openings without increasing the size of the entire trap. Such a trap is less likely to suffer pressure drop and is highly durable.
    • 用于柴油发动机的颗粒捕集器具有高的颗粒捕集能力和再生能力以及低压降,而且紧凑且便宜。 该捕集器具有由耐热金属纤维织物形成的多个锥形过滤构件构成的过滤元件。 过滤构件彼此具有不同的直径,并且同心地嵌套在另一个内部,使得相邻的过滤构件相反地定位。 每个过滤构件在其大直径端处连接到紧邻的外部过滤构件的小直径端,以交替地关闭相邻过滤构件之间的间隙的排气入口和出口端。 如此形成的过滤元件安装在设置在排气管线中的金属壳体中,并用作颗粒捕集器。 通过这种布置,可以在不增加整个陷阱的尺寸的情况下增加过滤器和排气入口的颗粒捕获面积。 这种陷阱不太可能遭受压力下降并且是高度耐用的。

    • A method for producing a silver salt of an organic acid, which comprises steps of reacting (1) a solution containing silver ions in water or in a mixture of an organic solvent and water, with (2) a solution or suspension containing an alkali metal salt of an organic acid in water, in a mixture of an organic solvent and water, or in an organic solvent to prepare a silver salt of an organic acid, and removing a byproduct salt by a desalting operation, wherein a dispersing agent having a molecular weight of 3000 or less is added and dispersed during a time period of from before the reaction to before the desalting operation. There is provided a method for producing a silver salt of an organic acid, which can provides low fog, high sensitivity and high concentration of blackening when it is used for photothermographic materials, and is suitable for the production of photothermographic materials having low haze and less image degradation after storage.

    • A polyester resin for toner comprising an acid component containing at least one selected from the group consisting of aromatic dicarboxylic acids and their lower alkyl esters, and an alcohol component containing at least one selected from the group consisting of bisphenol A derivative diols, wherein the content of aldehyde compounds, their decomposition products and by-products in the polyester resin is no more than 200 ppm. Toner polyester resins and toners are obtained which do not generate irritating odors even upon melting and kneading during the toner production or upon heating during the copying process, which provide clear images with no haziness due to reduced light permeability of the copy material, which have a wide range of color tone reproduction, and which provide excellent image precision on copied print.
