Abstract: A method and apparatus for increasing the emission amount of red such that it is made the same as the emission amount of green and blue, to enable the application state of the fluophors to be easily tested within a short time. Light from a discharge lamp of the short-arc type in which the arc tube is filled with cadmium and rare gas and which has emission lines between 200 nm and 230 nm is radiated onto fluophors of a test article such as the substrate for a display. The fluorescence produced by these fluophors is received by a CCD sensor, and displayed in a display part, and thus the application state, such as faults of the fluophors or the like, is checked. The images picked up by the CCD camera can also be input to a control device and thus testing can be automated.

Abstract: A device for exposing several rows of mask patterns on a strip-shaped workpiece without the device becoming larger and the rolls having to be replaced is achieved as follows: A strip-shaped workpiece is transported. When a first exposure area of the first row reaches a projection site on a workpiece carrier (3), the strip-shaped workpiece (Wb) is held by vacuum. A mask (M) is positioned relative to the strip-shaped workpiece and the first exposure area is exposed. Then, the strip-shaped workpiece is held by the workpiece suction devices (8, 8′). The movement devices (9) are driven and the strip-shaped workpiece is moved in the direction which orthogonally intersects the transport direction so that a second exposure area of the second row reaches the projection site on the workpiece carrier. The mask is positioned to the strip-shaped workpiece and exposes the second exposure area.

Abstract: A main frames having bottom and top frame parts for concrete molding machines of the kind which are used in making slabs or blocks for covering surfaces and erecting walls are usually made by welding together cut standard steel sections of the types HEM, RHS, UNP, etc. The requirements to materials and welds at the making of bottom frames of this kind are high due to the fact that welded structures subjected to vibration only has 10-15% of the basic material strength in the welding zones. Thus, the main frame has a bottom frame part (40) formed of two flame cut bottom plates (42, 44) arranged in parallel as an upper plate (42) and a lower plate (44) and forming the basic shape of the bottom, the bottom plates (42, 44) being interconnected by at least two longitudinal plates (46, 48) and a number of transverse plates (50, 52, 54). In this way, substantial savings are achieved as the main frame can be made with fewer or no welds in the critical areas, or with welds of a lower class.

Abstract: To prevent lamp extinction during dead time of an inverter circuit of a full bridge system, to reduce delays of the rising time and the falling time of rectangular waves which have been output by the inverter circuit and to prevent formation of a phenomenon of momentary darkening of the radiant light, the discharge lamp is operated with an alternating current with rectangular waves which is produced by an inverter circuit of a full bridge system. When the inverter circuit of the full bridge system is driven a dead time is taken in which all switching devices are turned off. In the rear stage of the inverter circuit of the full bridge system, there is an inductance. The value of the inductance is fixed such that LL≧VL/IL·Td (VL being the luminous voltage of the discharge lamp, IL being the current and Td the dead time). Current can flow in the discharge lamp during the dead time by the energy stored in this inductance.
