Abstract: A light source bulb in an automotive headlamp having a lamp chamber defined by a lamp housing and a lens, where the lamp chamber includes a reflector and the light source bulb arranged therein. The reflector includes a reflecting surface constituted by a complex reflecting surface. The light source bulb includes a high-beam filament arranged obliquely below and behind with respect to a low-beam filament. When lit, high and low beam distribution patterns are formed by entire-surface reflection light distribution control of the reflecting surface. The light source bulb is used for right traffic and for left traffic. A second support wire is, in a side view of said light source bulb, bent to rearward of the rear end of said high-beam filament and positioned above the lower end of said low-beam filament.

Abstract: In first to third support wires (12, 13, 14) connected to a low beam filament L and a high beam filament H, which are arranged in the light source bulb 9, a bent portion 13a is formed by bending the second support wire 13 from a curved portion 13c towards the first support wire at an obtuse angle &thgr;2, and each rear lead Lb, Hb of the low beam filament L and the high beam filament H is connected to the bent portion 13a. Moreover, a bent portion 14a is provided by bending the third support wire 14 from a curved portion 14c towards the second support wire at an obtuse angle &thgr;3, and a front lead Ha of the high beam filament H is connected to the bent portion 14a.

Abstract: The low beam filament and the high beam filament are disposed in such a positional relationship as the virtual image of the irradiated portion of the high beam filament does not produce glaring light in the low beam light distribution pattern. As a result, it is made possible to effectively utilize near 100% of light incident on the reflecting surface of a reflector and to obtain good low beam light distribution pattern and high beam light distribution pattern.

Abstract: A solid-liquid separator and a process for washing the same wherein SS (sended solids) caught in space portions of a filter medium in a tank are caused to flow out from the space portions and be suspended while at least part of the filter medium is maintained in a fluidized state by air washing, and rapid drainage through a lower portion of the tank causes the SS in the suspended state to be rapidly removed without being again caught into the space portions of the filter medium.

Abstract: A process for treating organic waste water in which a first step provided the stage precedent to a second step using an aerobic filter bed employs an upward flow type solid-liquid separator packed with a filter medium, with the SS (suspended solids) removal at the preceding stage being performed at a high SS removal rate and in a short time.
