Abstract: A method of manufacturing an armature coil, which comprises a printed coil obtained by printing and arranging a plurality of sets of unit coil groups, each comprising an even number of unit coils, on a belt-like, thin and pliable insulating material, and a pliable insulating material overlaid over and wound together with the printed coil, wherein the gaps between the printed coil and the insulating material and between the adjoining material layers are filled for fixing in the state the printed coil and the insulating material have been wound and laminated into a cylindrical shape, is featured in that a thermoplastic adhesive material is applied to the surface of the insulating material, and a tailing end of the insulating material is adhered to the adjoining inner peripheral layer by heating at least in the step of winding and laminating the printed coil and the insulating material into a cylindrical shape.

Abstract: An armature coil has sets of unit coil groups, each comprising an even number of unit coils, which are printed and arranged on a belt-like, thin and pliable insulating material to form a printed coil. The printed coil is wound and fixed into a cylindrical shape, the armature coil being featured in that the gap between adjacent conductors of the unit coil groups located on the outer periphery side of the cylindrical shape is set larger than the gap between adjacent conductors of the unit coil groups located on the inner periphery side thereof such that the conductors of respective unit coils are axially arranged to take the same angle in the circumferential direction.

Abstract: A refrigerant flow rate control device for the refrigeration cycle of an air conditioning system of an automotive vehicle which is driven by a vacuum actuator includes a communication passageway for equalizing pressures applied to opposite ends of a valve body. The valve body has an intermediate portion maintained in communication with the atmosphere and connected to the vacuum actuator.

Abstract: A tape drive device in which a cavity is formed in a reel hub provided for supplying or taking up a tape-shaped information recording and reproducing medium such as a magnetic tape or a film. A motor including a rotor unit and a stator unit is partly or wholly received within the cavity of the reel hub, and the rotating force generated by the rotor part of the motor is transmitted directly or through a reduction gearing to the reel hub to cause rotation of the reel hub.

Abstract: An electric motor having a rotor consisting of a disk-shaped multi-polar magnet circumferentially sectioned to have a plurality of magnetic poles, a stator consisting of a pair of superimposed star-shaped flat driving coils, said driving coils being disposed facing said magnet, said driving coils being arranged to be supplied with respective alternating currents having a phase differential of 90.degree. thereby to drive the disk-shaped magnet, said motor further comprising a speed detecting coil having a plurality of radially disposed generating wire elements, said generating wire elements being disposed within a magnetic field of said magnet and being connected in series, whereby a signal having a frequency corresponding to the revolution speed of said disk-shaped magnet is induced in said speed detecting coil.

Abstract: An electric motor comprises a rotor constructed by a disk-shaped multi-pole magnet secured to a rotary shaft and rotatably supported, and a stator constructed by a pair of star-shaped flat drive coils arranged adjacent and opposing to the disk-shaped multi-pole magnet. Sinusoidal wave currents, the phase angles of which differ by 90.degree. from each other, are supplied to the pair of drive coils to drive the magnet. A speed detection coil having a plurality of power generating strands is arranged in a field of the magnet and a field of the drive coils to produce a signal having a frequency corresponding to a rotational speed of the magnet.

Abstract: Arginine or lysine salt of acid cephalosporins can be administered parenterally, e.g., by intramuscular injection, with no substantial pain. Preferred acid cephalosporin salts are l-arginine or lysine salts of N-[7-(.alpha.-sulfophenylacetamido)ceph-3-em-3-ylmethyl]-pyridinium-4-carb oxylate, N-[7-(.alpha.-sulfophenylacetamido)-ceph-3-em-3-ylmethyl]-(4'-carbamoyl)py ridinium 4-carboxylate, 7-cyanoacetamido-cephalosporanic acid, 7-(2'-thienylacetamido)-3-[6"-(3"-methylpyridazinyl)thiomethyl]-ceph-3-em- 4-carboxylic acid 2"-oxide, 7-tetrazolylacetamido-3-[5'-(2'-methylthiadiazolyl)thiomethyl]-ceph-3-em-4 -carboxylic acid and 7-(2'-thienylacetamido)-cephalosporanic acid.

Abstract: A video signal reproducing system comprising means for driving a web of recording medium such as a tape at a constant speed, a self-scanned linear photoelectronic image device disposed for scanning in a direction perpendicular to the traveling direction of the recording medium, a clock pulse generator for applying clock pulses to this image device, and a light source for illuminating the recording medium, whereby information optically recorded on the recording medium can be scanned in a two-dimensional fashion to reproduce a video signal such as a television signal.
