Abstract: Zum Entzerren von Lesesignalen, die auf einem magnetischen Aufzeichnungsmedium (12) aufgezeichneten Daten zugeordnet sind, ist in der Schaltungsanordnung ein Entzerrerfilter (20) vorgesehen, das einen Frequenzgang aufweist, der durch die Laplace-Transformierte <IMAGE> dargestellt wird. Der Frequenzgang des Entzerrerfilters (20) weist in der komplexen Ebene bei niedrigen Frequenzen eine Nullstelle und bei hohen Frequenzen eine Polstelle auf. Zusätzlich kann eine Schaltstufe (16) vorgesehen sein, die das Entzerrerfilter (20) immer dann überbrückt, wenn Daten mit einer geringen Aufzeichnungsdichte auf dem Aufzeichnungsmedium (12) gespeichert sind. Die Schaltungsanordnung wird vorzugsweise bei Floppy Disk-Geräten eingesetzt und die Schaltstufe (16) wird durch einen Spurzähler (22) gesteuert, so daß das Entzerrerfilter (20) nur beim Lesen von Daten von den inneren Spuren eingeschaltet ist. Dem Entzerrerfilter (20) kann zur Erhöhung der Störsicherheit ein Gaussches Filter (24) nachgeschaltet sein.

Abstract: A process for forming a fluoroalkyl acrylate polymer film on a substrate by plasma polymerization. The fluoroalkyl acrylate polymer film has a high sensitivity to high energy rays and an excellent resolving power, and is very useful as a resist film. The plasma polymerized film of the invention has little pinholes, and is endurable to dry etching. A patterned resist film is prepared by irradiating the film with high energy rays to form a latent pattern and developing the latent pattern by either a wet process using a solvent or an oxygen or oxygen-containing gas plasma etching. Also, a pattern can be formed in the film by only electron beam irradiation. The pattern formation can be attained by electron beam delineation without development treatment. The pattern formation by electron beam delineation is promoted by heat treating the delineated film at a temperature not less than the glass transition temperature of the polymer under reduced pressure or by treating the delineated film with hydrogen or an inert gas plasma.

Abstract: Novel indole derivatives of the general formula I
     can be obtained by reacting, directly or indirectly, N,N-dimethyl-3-indolemethylamine with a Schiff base of the general formula II,
     In these formulae R' is cyano or methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl or butoxycarbonyl, and 0 is phenyl. The reaction is performed in the presence of a base, with or without the use of a catalyst. The successive hydrolysis of the indole derivatives of the general formula I in the presence of an acid and of a base gives tryptophane.

Abstract: A prism polarizer comprising a pair of anisotropic crystal prisms (1,2) which are faced to each other. Each of said crystal prisms is composed of an crystal which has an optical charac- eristicthatthe difference between the square of the refractive ndex for extraordinary rays and the square of the refractive ndex for ordinary rays is larger than 1. The angle 0 of incidence of a beam upon the facing plane (3) of said pair of prisms (1,2) is equal to the Brewster angle for the refractive index for P-polarization rays (ℓT). P-polarization rays are tarn- smitted through said facing plane. S-polarization rays (tR) are totally reflected at said facing plane (3). Thereby, said incident beam is separated into two polarized beams. Each of said pair of prisms is formed so that each polarized beam is totally reflected within each prism and that the separated outlet beams from said pair of prisms are parallel with each other.

Abstract: The invention relates to metallurgical lances. Normally such lances are formed by a heavy metal tube encased in a refractory sleeve and because of their relatively long length such lances flex in use thereby propagating cracks in the refractory and encouraging the growth of cracks that are otherwise formed during shock loading of the lance as it enters the bath of metal and because of differential expansion that occurs between the refractory and the tube. The object of the invention is to provide a lance of high rigidity and reduced tendancy to cracking and spalling which objective is met by a metallurgical lance (1) having a tubular member (2) for the passage of gas or the mixture of gases and solids, said member being encased in a sleeve (3) of an appropriate refractory, there being arranged around the periphery of the tubular member, and spaced therefrom, a number of longitudinal reinforcing members (4), also encased in the refractory sleeve.
