Filed: 1990-07-30
Abstract: PURPOSE:To prevent burning of an air cone without interfering with the combustion efficiency and stabilize the combustion by providing inside an air cone an internal air cone of smaller diameter in such a manner as to form one additional supply channel for combustion air. CONSTITUTION:Inside an air cone 6 there is provided an internal air cone 5 whose diameter is smaller than that of the air cow 6 but larger than that of a flame baffle ring 3. Combustion air A, sent from a blower and through an air damper 8 and into an air box 7, is supplied to the combustion part through air-supply channels A1 formed by air-passage holes 4c opened through the bottom plate 4b of a flame-holding cup 4, supplied through an air-supply channel A2 between a gas header 2 and the flame- holding cup 4, an air-supply channel A3 between the flame baffle ring 3 and the internal air cone 5, and an air-supply channel A4 between the internal air cone 5 and the air cone 6. The air-supply channel A4 is for cooling the air cone 6 and the internal air cone 5 and for preventing their burning; this channel supplies air to the peripheral part of a flame-projecting hole 6a from behind a throttle plate 6a attached to the forward end of the air cone 6 and the air effects straightening of the projected flame, stabilization of the combustion, and enhancement in the combustion efficiency.

Title: Method for applying hard coating material or protective coating material of optical disk
Inventor: MIYASHITA HIDEO
IPC: G11B7/26
Filed: 1991-08-09
Abstract: PURPOSE:To eliminate the resin drooling of the hard coating material or protective coating material of the optical disk. CONSTITUTION:The velocity of gaseous downflow is successively decreased with an increase in the rotating speed of the optical disk in the case of application of the hard coating material or protective coating material by a spin coating method on the optical disk in the gaseous downflow. The grain sizes of the resin shake off at the time of starting the rotation of the optical disk are large and, therefore, the resin splashes successively downward from the optical disk in the gaseous downflow if the velocity of the gaseous downflow is successively decreased with the increase in the rotating speed of the optical disk. The particle sizes of the resin shaken off on increasing of the speed to higher speeds are successively fined and the misty resin is formed, but the mists are splashed in nearly a horizontal direction without flowing along the flank of the optical disk since the gaseous downflow is slow. The generation of the resin drooling on the flank of the disk is thus prevented.
