摘要： An illumination light communication device includes a power supply unit controlling a load current in a light source unit to be maintained constant based on a dimming signal; an impedance unit series connected to the light source unit; a switch element parallel connected to the impedance unit to connect/disconnect the impedance unit with the light source unit; and a control unit controlling on/off of the switch element to modulate a light intensity of the light source unit such that a binary communication signal is superimposed on illumination light therefrom. The control unit controls the impedance of the impedance unit such that a difference between magnitudes of the load currents respectively when the pulse of the communication signal is superimposed and is not superimposed is maintained constant regardless of a dimming rate of the dimming signal in a range of a dimming rate equal to or greater than a predetermined level.

摘要： Light which tries to enter a diffuser plate 3 at an angle which exceeds an angle at which a percentage of reflected light increases rapidly (that is, the incidence angle θ=70 degrees) is all reflected by a reflecting surface 21 and then enters the diffuser plate 3. Therefore, a pseudo light source is formed by light which was collected near a connection point between adjacent reflecting surfaces 21 out of the emitted light of the discharge lamps 1. So, the brightness between the adjacent discharge lamps 1 is increased, and it is possible to reduce unevenness in brightness. Furthermore, since the discharge lamp 1 is housed inside the reflecting surface 21 whose cross-sectional shape is a parabola, it is possible to reduce the distance between a reflecting plate 2 and the diffuser plate 3, as compared with the prior art, and to reduce the thickness dimension in the anteroposterior direction.

摘要： A method of manufacturing tubes filled with powdery and/or granular substances, such as flux-cored welding wires. A tube filled with a powdery and/or granular substance is continuously manufactured by forming a metal strip being fed in its longitudinal direction into an unwelded tube (1a) using forming rolls (2), feeding a powdery and/or granular substance (F) into the unwelded tube (1a) being formed through its opening, butt-welding together fringing edges of the opening, and reducing the diameter of the welded tube (1b). An allowable minimum heat input below which cold cracking occurs and a maximum allowable heat input above which spatters whose diameter is not smaller than 0.83 times the inside diameter of the finished tube are generated are determined in advance, and the butt welding is performed with a heat input larger than the allowable minimum heat input and smaller than the allowable maximum heat input. This eliminates the risk of breaking in reducing the diameter of the welded tube (1b) filled with the powdery and/or granular substance (F).
