Title: Combustion apparatus for liquid fuel
Inventor: OOMUKAE YOSHIZOU
IPC: F23D3/18
Filed: 1984-03-27
Abstract: PURPOSE:To improve combustion efficiency, and to reduce environmental pollution by a discharging gas extremely while remarkably widening the regulating width of the quantity of combustion by mounting a regulator regulating the quantity of fuel evaporated at an approximately predetermined air-fuel ratio by adjusting the flow rate of air introduced into a combustion chamber while fitting an exhaust gas purifying catalyst in a flow path for a combustion exhaust gas discharged from a combustion apparatus section. CONSTITUTION:An exhaust gas purifying catalyst 15 having honeycomb structure is fitted while the flow rate of exhaust gas from a discharging port 16 is changed by adjusting the flow resistance of a gas by a regulator 17, thus controlling the flow rate of air introduced to a combustion chamber 5, then further controlling the quantity of fuel evaporated from the nose section of a wick 1 by the change of the flow rate of air introduced to the combustion chamber. Consequently, an approximately prescribed air-fuel ratio is maintained regardless of the alteration of the quantity of combustion. The combustion chamber 5 is supplied with air by a natural convection based on the heat value of a combustion apparatus, combustion exhaust gas is mixed with fresh air forwarded from air chambers 7, 11 through holes 19, 20 in a mixing chamber 14 and enters into the catalyst 15, and an injurious material is removed or reduced remarkably and discharged to the outside from the discharging port 16.

Title: Image forming material and production of release layer
Inventor: SASA NOBUMASA
IPC: G03F7/004
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To improve the reproducibility for small dots, transfer property and sensitivity and to reduce the production cost by forming the uppermost release layer having photosensitivity or reactivity with a color photosensitive layer during exposure and forming a color photosensitive layer which changes its adhesion property by irradiation with light. SOLUTION: This image forming material has a multilayered release comprising two or more layers, and color photosensitive layers in this order on a base body. The uppermost layer of the release layer is the most distant layer of the two or more layers from the base body. The release layer is obtd. by preparing a resin (matrix resin) having physical properties suitable for the release property, such as thermoplasticity that the resin is softened by heating, and introducing reactive groups which react with radicals produced in the photosensitive layer by exposure or introducing photosensitive groups which produces reactive radicals with the photosensitive layer. As for the photosensitive compsn., a well-known photosensitive compd. which changes its adhesion property by exposure can be used.  It is preferable to use a photosensitive compsn. which decreases its adhesion property by exposure.
