Abstract: PROBLEM TO BE SOLVED: To smoothly mixing fuel with air for facilitating atomization in a device with a piston having a recessed piston ball formed at its upper surface by providing a projection protruding to the side of a combustion chamber in the piston ball of the piston. SOLUTION: A piston ball 18 formed in a recessed shape at an upper surface of a piston 8 is formed such that its substantial central part is directed to the side of an injector 20. The injector 20 for injecting fuel to almost the central part of the ball 18 is disposed at a left part of a cylinder head 6. In the ball 18 a projection 22 is formed to protrude to the side of a combustion chamber 10. This projection 22 is formed so that its radius of curvature may be positioned on a plane including an axis 10C of the chamber 10 and an axis 20C of the injector 20 and the radius of curvature is formed to be almost in conformity with that of the ball 18. Accordingly, fuel injected from the injector 20 is diffused to facilitate the mixing of fuel-air and atomization of fuel.

Title: Heat treatment method of and apparatus for industrial wastes
Inventor: POORU GUIROOMU
IPC: F23G5/00
Filed: 1979-12-04
Abstract: A method and apparatus for the heat treatment of industrial wastes wherein at least some of the constituent materials of the wastes are subjected to combustion and/or to pyrolysis to produce flue gases and, in some applications, a residue. The supply of an oxygenated combustion-supporting gas to the wastes is regulated as a function of at least one sensed predetermined characteristic of the flue gases. The oxygenated gas may be a mixture of air and substantially pure oxygen, the feed rate of one or both of these being regulated in response to the sensed temperature and/or oxygen content of the flue gases. Such regulation maintains the oxygen content of the flue gases within the range of from 0 to 7%; and the temperature of the flue gases may be maintained from 400 DEG  to 1200 DEG  C. and, preferably within a range of 50 DEG  C. in this region.

IPC: G03F7/34
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To form a plurality of sheets of color proof through a single exposure by subjecting an image forming material comprising a photosensitive layer and a silicon rubber layer formed sequentially on a substrate to scanning image exposure thereby exposing the surface of the substrate in imagewise and transferring the imagewise ink layer to an image receiving sheet. SOLUTION: A photosensitive layer containing near infrared ray absorbing agent and a silicon rubber layer are formed sequentially on a substrate to produce an image forming material which is then subjected to scanning image exposure with near infrared rays from the silicon rubber layer side. The photosensitive layer is then subjected to abrasion at the exposed part and removed together with the silicon rubber layer side thus exposing the surface of the substrate imagewise. An ink foil is then laminated on the surface of the image forming material and eventually stripped thus providing an imagewise ink layer at the exposed part. Subsequently, an image receiving sheet is laminated on the image forming material which is eventually stripped and the imagewise ink layer is transferred onto the image receiving sheet thus forming a color material image.  According to the arrangement, a plurality of sheets of color proof can be produced directly from a digital image through a single exposure.
