Title: Luminous flame generating combustion device
Inventor: NAKAMACHI ICHIROU
IPC: F23D14/74
Filed: 1984-03-27
Abstract: PURPOSE:To complete combustion with a relatively short flame and to form flame having a high radiation rate, by a method wherein the forward end of a fuel pipe is secured to an annular flame stabilizing plate, and an air nozzle is located on the central axis of a burner in a condition that the annular flame stabilizing plate is protruded. CONSTITUTION:Fuel gas is injected through a fuel pipe 2, and the air for combustion is introduced from the direction of arrow marks, flows out through the outside 5 of a flame stabilizing plate and an inner opening part 6 of the flame stabilizing plate, and a recycling flow 7 is formed on the following stream side of an annular flame stabilizing plate 3. Since the recycling flow 7 is formed throughout the whole following stream of the flame stabilizing plate 3, fuel injection flow is spread along the flame stabilizing plate 3, and is formed integrally to form a hollow cylindrical flame 8. During combustion, a normally-constant amount of the air is injected through an air nozzle 4, and this, even during running at a low load, prevents straight advance properties of the hollow cylindrical flame 8 from being rendered ineffective, and enables prevention of raising of the flame 8 due to lowering of a velocity of flow.

Title: Image forming material
Inventor: SHIRAISHI SHIYUUHEI
IPC: G03F7/095
Filed: 1983-04-05
Abstract: PURPOSE:To obtain an image forming material which can form an image with good reproducibility down to detailed parts and does not require special solvent for a developing soln. by providing an image layer contg. an alkali soluble resin, a PVA haing a degree of saponification of a specific value or above and a coloring material on a base, and a photopolymer layer that can be developed by an alkali thereon. CONSTITUTION:An alkali soluble resin suppresses adequately the penetration of a developing soln. into an image layer, and improves developability as it dissolves quickly. A PVA having >=80mol% degree of saponification is used to improve an osmosis property of the developing soln. and to permit development by a weak alkali soln. as well as to prevent penetration of the photopolymer soln. in the image layer. On the other hand, if the degree of saponification is <=80mol%, the PVA is water soluble and therefore the development progresses early and the reproducibility in the detailed parts of the image is poor. A pigment or dye of any color is usable as the coloring material and any photopolymer to be used for the photopolymer layer is usable as far as the polymer can be used for development of a positive or negative type image with an aq. alkali soln.

Abstract: PURPOSE:To obtain a filter whose occupancy area at the time of incorporating it into a hybrid integrated circuit is small and which can obtain a sufficiently low cut-off frequency by providing a thin metallic layer and a plate-shaped ferromagnetic material mounted on the thin metallic layer on a conductor signal line. CONSTITUTION:The filter consists of the conductor signal line 2 formed on a substrate 1, an insulating material layer 3 accumulated on the conductor line, the metallic layer 4 accumulated moreover on the insulating material layer 3, and the plate-shaped ferromagnetic material 5 mounted on the metallic layer 4. The conductor signal line 2 and the metallic layer 4 form a micro strip line. As the metallic layer 4 is formed more thinly than the skin depth of a using frequency, an electric field induced on the metallic layer 4 by a signal on the conductor signal line 2 is affected by the plate-shaped ferromagnetic material 5 on the metallic layer 4 and an inductance is generated at the electric conductor signal line 2. Furthermore, as the metallic layer 4 is grounded, capacitance is generated between the conductor signal line 2 and the metallic layer 4 and the low pass filter of the sufficiently low cut-off frequency is obtained.
