Patent JP-S60186610-A (JP)
Title: Liquid fuel combustion device
Inventor: UNO KATSUHIKO
IPC: F23D3/10
Filed: 1984-03-06
Abstract: PURPOSE:To provide a stable combustion state even when allowed to stand after ignition, and suppress a large upstanding flame in sharply increasing the intensity of combustion, by providing a small hole range at an area above the vicinity of wick through at least one of inner and outer flame cylinders, excepting for the air ports group of lowermost stage, and a large hole range immediately above the small hole group. CONSTITUTION:As a small hole range 16 exists, an area adjacent to the upper end of wick 14 is cooled down by an air from an air port 8b without forming a flame (f). Even when the fuel is burnt less intensely, a temperature can be maintained low at an area adjacent to the upper end of wick. A black-colored heat resistant metal oxide paint is coated from the lower end to the upper end of small hole range 16 to prevent the reflection of heat, increase thermal capacity and prevent red-heat for thereby maintaining a low temperature level. In this way, only a marginal temperature difference occurs at an area adjacent to the upper end of wick 14 between when the fuel is burnt intensely and less intensely. The vaporizing quantity of fuel does not increase abruptly even when the fuel is sharply turned to an intense combustion. Thus, no large upstanding flame may develop above the combustion cylinder. Moreover, a stable flame (f) can be formed in a large-sized range even when allowed to stand as it is after ignition.

Title: Apparatus for manufacture of semiconductor
Inventor: YOSHIDA NAOTO
IPC: H01L21/203
Filed: 1985-03-04
Abstract: PURPOSE:To protect a substrate surface from contamination caused by welding material when the substrate is stuck on a substrate holder with the welding material by a method wherein a protruded part with a diameter smaller than the substrate diameter is provided on the substrate holder. CONSTITUTION:A protruded part 2a provided on a substrate holder 2 is approximately 1mm in height and, if a substrate 1 is circular, preferrably 2mm smaller in diameter than the substrate 1. Indium 3 is applied on the surface of the protruded part 3a only and the substrate 1 is stuck on the indium 3. Therefore, when the welding material is melted, it is covered by the back side of the substrate 1 and does not evaporate directly toward the surface of the substrate 1 and hence the surface of the substrate 1 can be protected from contamination caused by the indium 3 as possible. As the substrate holder 2 is larger than the substrate 2, the temperature gradient produced in such a way that the temperature of the circumference part of the substrate 1 is lower than that of the other part because of the heat radiation from the circumference is avoided and hence the substrate 1 can be heated uniformly.
