摘要:
A photoconductive switch comprises a first layer (1), two contact layers (2, 3) arranged on said first layer and connectable to different potentials for applying a voltage thereacross, said first layer being adapted to be conducting upon applying a voltage across said contact layers when exposed to light from an illumination source of an energy high enough for lifting charge carriers from the valence band to the conduction band of the material of said first layer. The illumination source is an excimer lamp, in which unstable electronically excited dimers are formed when a voltage is applied across first and second electrodes (12, 13) separated by a gas or gas mixture. The dimers so formed decompose into two gas atoms while emitting a photon of an energy suitable for lifting charge carriers from the valence band to the conduction band of the material of the first layer.

A photoconductive switch, having at least a part of a first layer doped with dopants providing substantially no free charge carriers for charge transport between the electrodes at the normal operation temperature of the switch, has the nature of the doping, i.e., concentration, type (n or p). The dopants, varied from the first side to an opposite, second side of the first layer for co-operating with the intensity distribution of the light emitted by an illumination source, strikes the first side versus energy so as to obtain a substantially even creation of free charge carriers throughout the depth of the first layer from the first to the second side when illuminated by the illumination source.

摘要:
Surface coating method for deposition of a chemically bonded ceramic coating on a substrate, includes the steps of preparing a curable coating slurry, depositing a coating of the slurry on at least a section of the substrate surface, and hardening the slurry. The step of preparing a curable coating slurry includes mixing calcium aluminate powder with water and at least one water-reducing-agent, such that a water-to-cement ratio in the range of 0.1 to 0.9 is achieved.
摘要:
A label printer for a bar code comprising a heat printing head having resistance dots for printing the bar code on a heat sensitive label. A motor feeds the label with a constant speed, e.g. 10 cm/sec. The printing head receives electrical power pulses form a control unit which receives signals from a memory unit and a CPU-unit. The CPU-unit receives external signals form e.g. a weighing machine, a keyboard or an external computer and computes the bar code, check figures or the like. The printing head comprises a substrate including the electronic circuits and the resistance dots. The substrate is supported by a metal block which comprises temperature sensors which control the power pulses to the resistance dots.
