摘要:
This invention relates to a “structure of reformed traffic light”, comprising of a signal box enclosing at least one set of light sources arrayed in square or round matrix. It features a set of light source adopting Light Emitting Diodes (LED) as lamps and each LED contains at least red and green semi-conductor chips (hereinafter abbreviated as chip) to emit red, green and amber lights. Furthermore, it is the traffic control signals that control the lights. By applying the foregoing features, an all-in-one traffic light is invented with advantages such as lighter weight, reduced dimensions and cost effectiveness for installation, repair and maintenance in comparison with the existing traffic lights.

An optical calibration and testing device for machine tools includes a light source unit, a beam splitter, and at least one photo detector. The light source emits a laser light hitting the beam splitter and is split into two beams. One is perpendicular to the foundation of the light source unit, and the other is parallel with the foundation so as to test straightness, inclination angle, verticalness, vertical column inclination, vertical column parallelism and guide bar inclination of a machine tool. If there is no tested error, the position of the testing light spot coincides with that of the initial light spot. If there is an error, the position of testing light spot varies according to the error.

A disc brake pad made of multi-compounds and a manufacturing process thereof comprises a brake member compositely made of at least one frictional compound. In other words, the surface of the brake member is formed of more than two kinds of abrasion areas, for example, the surface of the brake member is made of for the frictional compound use in a wet condition and another frictional compound for use in a dry condition, such that the frictional compounds may be applied to the brake member solely or together so as to accommodate in different conditions.

An improved structure of traffic light is mainly to install in a signal box at least one illuminant unit, which is a square or round lantern composed of a plurality of LED lamps arrayed in matrix or honeycomb. And, the LED lamps comprised in the illuminant unit are in monochrome red, yellow and green and arrayed in checkered pattern to display red, yellow and green lights. Design of the illuminant unit effectively reduces weight and dimensions of the signal box so as to result in cost reduction.
