Title: Liquid fuel burner device
Inventor: ITOU MASARU
IPC: F23D11/44
Filed: 1982-11-09
Abstract: PURPOSE:To prevent a part, unnecessary for evaporation of liquid fuel, from being heated to a high temperature, to shorten a preheating time, to improve durability, and to reduce production of an offensive odor, by partially installing heat collecting fins to the outer surface part of an evaporating tube. CONSTITUTION:High temperature exhaust gas, generated resulting from combustion, is exchausted through a combustion space 69 from a combustion exhaust gas nozzle 60, but in which case, heat collecting fins 70 formed on the outer periphery surface of an evaporating tube 50 are heated to recover the heat to the evaporating tube 50. The heat collecting fins 70 are partially formed on the outer periphery surface of the evaporating tube 50, and besides, the inner surface of the evaporating tube corresponding thereto forms an evaporating surface, whereby the combustion heat, recovered by the heat collecting fins, concentratedly heats an evaporating surface on which liquid fuel is evaporated, and other part is maintained at a relatively low temperature. This prevents the evaporating tube 50 from being entirely heated to a high temperature, reduces dissipation of the heat, prevents an increase in the heating temperature of an oil feed nozzle 55, enables prevention of production of an offensive odor after fire-extinguishing, and permits improvement of durability due to a reduced part which is heated to a high temperature.

Title: Magnetic head device
Inventor: ARAI YOSHIO
IPC: G11B17/32
Filed: 1988-08-06
Abstract: PURPOSE:To suppress the occurrence of a resonance phenomenon and to prevent the reduction of a recording magnetic field and the lowering of a reproducing output by layering a plural number of gimbals and fixing them to a carriage. CONSTITUTION:A 1st gimbal 2 fitted with a magnetic head 4 is layered with a 2nd gimbal 3 to be fixed on the carriage 6 via a junction part 9. In this case, when both gimbals are deformed by periodical forced power generated between the magnetic head and a rotating disk, a friction resistance is generated between the 1st gimbal 2 and 2nd gimbal 3. Consequently, by increasing the friction resistance between both gimbals according to the surface roughness and shape of the gimbal, a viscous resistance is equivalently increased, and hence the resonance can be attenuated. By this method, the reduction of the recording magnetic field and the lowering the reproducing output are prevented.
