Abstract: This invention relates to an NC laser apparatus comprising the combination of a gas laser oscillator equipped with a cooling mechanism for forcibly cooling a laser gas by a blower and a cooler with a computerized numeric controller (CNC). The NC laser apparatus consists of gas temperature measurement means (15) for measuring the inlet gas temperature of the blower, casing temperature measurement means (16) for measuring a casing temperature of the blower and abnormality detection means (24). When the inlet gas temperature or the casing temperature exceeds a predetermined reference value, the abnormality detection means (24) regards it as abnormality of the cooling mechanism and stops the operation of the laser oscillator. Accordingly, abnormality of the cooling mechanism can be detected at an early stage and secondary breakage of the blower (10) can be prevented.

Abstract: L'écartement et le maintien à distance des divers disques dans des jeux de disques à friction d'embrayages et/ou de freins permettent d'éviter des couples de freinage et les pertes d'énergie qui en résultent. Des éléments d'écartement se présentant sous la forme de pièces magnétiques (8) qui sont insérées dans les supports de disques (1, 10) radialement par rapport aux zones marginales magnétisables de ces disques (4, 13) permettent d'obtenir une polarité de même sens dans les zones marginales en question. Il y a alors formation d'une force de répulsion mutuelle des divers disques (4, 13) en direction axiale. Les pièces magnétiques (8) étant solidement encastrées dans les supports de disques (1, 10), les défaillances et les difficultés de montage ainsi que les usinages spéciaux des disques sont évités. Les forces d'écartement elles-mêmes sont constamment indépendantes du positionnement et de la vitesse de rotation. L'emploi de bobines électromagnétiques (8A) permet d'annuler la force d'écartement, par exemple par actionnement du piston (19) et de maintenir ainsi l'effort du piston à une faible valeur.

Un échange d'informations entre divers utilisateurs du film, par exemple l'utilisateur de l'appareil photographique, le commerçant ou distributeur et le finisseur, s'effectue par l'intermédiaire de plusieurs pistes magnétiques longitudinales (C0, C1, C2, C3, F00-F29) sur le film, chaque piste étant réservée à l'écriture et à la lecture d'un ensemble prédéterminé de paramètres apparentés. Les emplacements des pistes réservées au finisseur ou retoucheur photographique remplissent la zone d'images exposée de chaque image. Les pistes réservées à l'appareil photographique (C0-C3) sont placées le long des bords du film entre les perforations (125) du film, ces perforations étant largement espacées à cet effet. Le procédé d'entrée de commandes de l'invention répond aux données se trouvant sur les pistes magnétiques spécialisées sur le film pour commander le procédé et stocker des données commandant l'entrée de commandes et la finition photographique.

Abstract: An illuminated display unit such as a board with a house number thereon or an advertising billboard, has a light guide panel. At least one electrical illuminating element is arranged in the vicinity of at least one lateral limiting edge thereof. The light guide panel serves for illuminating logo symbols, which are preferably in the form of film or of vapor coated layers, on the light guide panel. At least one of the lateral limiting edges of the light guide panel is provided with a light guide batten whose thickness is in excess of the thickness of the light guide panel and at least one of the illuminating elements is mounted in the batten. The transition between the light guide batten and the light guide panel is designed so as to have a high optical conductivity or transmittivity. The external surfaces of the light guide batten are provided at least partly with an inwardly reflecting layer. This makes it possible for the light of the illuminating elements, which are more especially in the form of LED's with a large diameter, to be fully introduced in substantially thinner light guide panels in order to reduce costs and weight.

Abstract: The invention relates to a fabrication method for an integrated MOS semiconductor device for the low-frequency range which has MOS components and conductor tracks (7) on a semiconductor substrate (1). According to the invention, the exposed surface (9) between said conductor tracks is rendered hydrophobic and this prevents the occurrence of leakage currents. Furthermore, according to the invention, in an integrated MOS semiconductor device in which the MOS components and the conductor tracks are covered with a protective layer (8), the surface of said conductor layer is rendered hydrophobic. This suppresses not only leakage currents, but also parasitic capacitances, advantageously resulting in an increase in the circuit yield.

Abstract: The differentiator circuit comprises a first current memory cell comprising capacitor C2, switch S2, transistor T2 and transistor T3 and a second current memory cell comprising capacitor C1, switch S1 and transistor T1. During one portion φ2 of each sampling period the input current i minus the current produced by transistor T1, which acts as a current source when switch S1 is open, together with appropriate bias currents to allow bi-directional input currents to be handled is fed  via  switch S3 to the first current memory cell. During another portion φ1 of each sampling period the input current plus an appropriate bias current is fed to the input of the second current memory cell. The switches S3 and S2 are open so transistor T2 acts as a current source giving an output  via  switch 54 at output 17 in addition to the output 15. The differentiated output signal is available throughout at output 15 but only during the portion φ2 of each sampling period at output 17. 
     The circuit corresponds to a backward Euler mapping from continuous time ideal differentiators. Corresponding circuits giving forward Euler and bilinear mappings are also disclosed as are circuits for lossy differentiators. Various alternative current memory cells are also disclosed.

Abstract: An etching process is described for etching aluminum containing III-V semiconductor compounds. The etch solution contains dichromate ion in acid aqueous solution in which the acid is either phosphoric acid or sulfuric acid. The etch solution is highly selective in that it etches the aluminum containing III-V semiconductor compounds without etching significantly other III-V semiconductor compounds not containing aluminum exposed to the same etching solution. The etching process is extremely useful in fabricating a variety of III-V semiconductor devices including heterojunction bipolar transistors, heterojunction field effect transistors and self-enhanced electro optic devices.
