Abstract: PURPOSE: A light source bulb in an automotive headlamp is provided which can be used both as a left-traffic light source bulb and a right-traffic light source bulb. CONSTITUTION: A fourth lead wire (LW40), since arranged in a shading coverage, is prevented from exposure to the irradiation lights from a low-beam filament (51) by the effect of the shading function of a high-beam filament (52). The front end of a third support wire in a semi-shading coverage, since bent to a curved surface, receives the irradiation lights from the low-beam filament (51) but with a minute area; and the light diffusion function of the bending curved surface acts thereupon. The lower end on the front end portion of a second support wire, since positioned above the lower end of the low-beam filament (51), is prevented from appearing above a light-shade boundary line. In either use as a right-traffic light source bulb or as a left-traffic light source bulb, lights from the low-beam filament (51) and the high-beam filament (52) reach the reflecting surface (40) of a reflector (4) without passing through a rear-end sealed part of a glass envelop, eliminating optical-path changes in the rear-end sealed part, production of glare light, and light-distributional problems. This results in freedom from virtual image glare, so that a single light source bulb can be used both as a left-traffic light source bulb and a right-traffic light source bulb.

Abstract: PURPOSE: In a semiconductor fabrication apparatus having a quartz tube and a flange, a method for exchanging the quartz tube producing impure particles is provided to improve process uniformity while allowing reuse of the flange to reduce cost. CONSTITUTION: The method begins with previously cleaning a used quartz tube by using a mixed solution of HF, H2O2 and H2O, and then cutting joint between the used quartz tube and the flange. The flange is then cleaned for thirty to sixty seconds by using again the mixed solution. After that, the flange is immersed in deionized water and then cleaned again for thirty to sixty minutes by using supersonic waves. Next, a cutting plane of the flange is abraded by an abrader. The abraded plane is then heated by a hydrogen torch and instantaneously joined to a new quartz tube. Then, an annealing is carried out to remove residual stress due to joining, and an abrading is performed again. Next, the annealing and the cleaning are repeated, and a drying step follows at a fixed temperature between 80 and 120°C for a fixed time between 2 and 8 hours.

Abstract: So as initially to fill a beer glass (6) only with foam which after at least one minute settles to yield a quantity of beer sufficient to fill the beer glass (6), the beer, while travelling from the barrel to the outlet spout (4), is made to flow through at least two pin-hole apertures (8, 12). After flowing through each of said pin-hole apertures (8, 12) the beer flows against a baffle plate (10, 14), which results in the formation of carbon dioxide gas bubbles by controlled release of carbon dioxide. The strongly foaming beer flows from the outlet spout (4) into a beer glass (6, 6') in which it collects exclusively or almost exclusively in the form of foam. After at least one minute the foam settles to yield a quantity of liquid corresponding to the amount of beer required for the beer glass (6, 6').
