Abstract: 1. Process for producing a polymerized, heat resistant resin of a high carbon black compatibility and a high pigment absorption, preferably for record carriers coated with aluminium, with two polymers being assumed of which one is a cellulose acetate, characterized in that initially the higher melting polymer is homogenized by kneading at about softening temperature, plasticizer being admixed in a quantity sufficient for transferring to the polymer the mechanical energy of the kneading process, that subsequently the lower melting polymer is added and this mixture is kneaded up to homogenization at a temperature approximately midway between the softening temperature of the higher melting polymer and that of the lower melting polymer (mean softening temperature), and that the copolymerizate thus obtained is processed to form a resin, adding pigments, if required.

Abstract: In order to improve the temperature constancy of induction boost in a standard working temperature range for fault current safety switches, a Ni-Mo-Cu-Fe alloy is provided whose nickel and copper content in a binary nickel-copper system is defined by a quadrangle of points A (80.5 wt. % Ni and 0 wt. % Cu), B (82 wt. % Ni and 0 wt. % Cu), C (70 wt. % Ni and 16.5 wt. % Cu) and D (70 wt. % Ni and 14.4 wt. % Cu) and whose molybdenum content, z, in wt. % satisfies the relation: 11/30 (x-68)</=z</=11/30 (x-63.5) with a given Ni content, x, in wt. % and the remainder of which essentially consists of iron and minor processing impurities. Such an alloy is worked into a 0.05 through 0.3 mm thick tape and wound into a toroidal tape core which is first annealed for about 30 minutes at temperatures between 900 DEG  and 1200 DEG  C. and is then tempered in accordance with its Mo content at the temperatures between 450 DEG  and 550 DEG  C. in such a manner that the magnetic anisotropy, K1, becomes equal to 0 at temperatures between -5 DEG  and +30 DEG  C. Such toroidal tape cores are particularly useful as sum current transformer cores or pulse-current-sensitive fault current safety switches, with a trigger current strength of 30 mA.

Filed: 1981-09-16
Abstract: The invention relates to a process for forming a patterned resist mask. 
     The performance of ethylene glycol alkylether developers, for positive methacrylate-methacrylic acid copolymer and terpolymer resists, is controlled by adding an organic complexing agent, such as citric acid, or a combination of a transition metal salt and a complexing agent, such as ammonium citrate, to the developer. The additives provide a consistent development rate, so that the maximum difference between the dissolution rates of the exposed and unexposed portions of the resist layer can be maintained, regardless of the developer purity.

Abstract: A semiconductor device comprises a substrate (42), having at one surface thereof a region (45) of uniform conductivity type covered by an insulation layer (43), formed with a window (RCW) through which a conductive layer (ME2) makes contact with the said region of the substrate. A source of atoms (DRCW) of the semiconductor material is provided in contact with the conductive layer, between the window and a major portion of the conductive layer, whereby diffusion of atoms from the source into the conductive layer serves to stabilize the concentration of semiconductor atoms in the vicinity of the window and so stabilizes the contact resistance between the said region of the substrate and the conductive layer.

Abstract: An automatic film threading device adapted for use with cameras or projection devices will drive the free end of the roll of film from a magazine along a film path and into the equipment. The threading mechanism comprises a drive for the reel and means for spreading the mouth of the magazine to free the film from the magazine. A second member moves into contact with the outer surface of the wound film to strip the free end from the roll of film and thread the same into a nip area between two drive rollers. The stripping member is biased toward the wound roll of film and a roller near the stripping finger engages the outer convolution of the wound film to hold the roll as the stripping finger contacts the film to direct the free end of the film off the reel. The means for spreading the mouth of the magazine comprise a pair of arms which extend into the magazine and which diverge from a pivot point adjacent one side of the magazine and a spring is provided for positioning and biasing the arms into the magazine.

Abstract: @ A paper feed and drive mechanism for use in a high speed printer comprises a pair of arms (22) which may be selectively positioned in a first lowered position, or in a second raised position. When the arms are in the lowered position, a line of contact (17) is formed between a pressure roll (20) and a drive roll (18) and a narrow printing gap is formed between the platen (26) and the inked ribbon. Spring (44) bias the pressure roll (20) onto the drive roll (18) and clips (34) mounted on the arms (22) hold the arms in the lowered position against the bias. Allowing the arms (22) to raise to a second position in response to the spring bias creates a gap between the pressure roll (20) and the drive roll (18) and a wide non-printable gap between the platen (26) and the inked ribbon. Additionally, a narrow tear bar slot (33) formed between a fixed saw tooth tear bar (32) and a backing plate (30) attached to the arms opens to form a wide space when the arms are raised. The wide space eliminates the necessity to thread the paper tape (12, 14) through the narrow tear bar slot (33).
