Abstract: An improved method of producing magnetic thin film with high coercivity and high squareness B-H hysteresis loop for a high density magnetic recording medium is provided by vacuum deposition of Co base binary or ternary alloy systems with Re, Ru or Os as its alloying elements. A co-deposition of cobalt (Co) and rhenium (Re), ruthenium (Ru) or osmium (Os) in a range of alloy composition by a sputtering method on a glass or metallic alloy disk substrate under a range of deposition rate, substrate temperature and sputtering inert gas pressure produces a magnetic thin film medium with a coercive force up to 800 Oe and a squareness ratio of its B-H loop up to 98%. These films can also be produced by de-composition of the alloy elements through other vacuum deposition methods such as electron beam, ion beam and thermal deposition of the alloy at a given range of substrate temperatures and deposition rates

Abstract: An electrically powered type ventilator for use in medical applications. 
     The ventilator incorporates an expansible chamber (20), a gas inlet/delivery port (21) communicating with the chamber (20), an electric motor (35) coupled to a rotatable shaft (39) and a motion translating mechanism (40, 41, 42) which couples the shaft (39) to the chamber (20) to impart expansion and compression strokes to the chamber. 
     In order to avoid problems which are associated with crank mechanisms which feature in prior art electrically powered ventilators, the motion translating mechanism (40, 41, 42) includes an element (42), preferably a positive drive link chain or belt, which is connected with the expansible chamber (20) and which is driven to move along a linear path during expansion and compression of the chamber. 
     Expansion and compression strokes are imparted to the chamber (20) preferably by use of two motors (35 and 36) which have their rotors mounted to a common shaft (37), with the first motor (35) being arranged to drive the rotatable shaft (39) in a first direction whereby successive compression strokes are imparted to the chamber and the second motor (36) being arranged to drive the rotatable shaft (39) in a second direction whereby successive expansion strokes are imparted to the chamber. 
     The extent of the expansion stroke is preferably determined by use of a timer device which operates to cause de-energisation of the second motor after elapsing of a predetermined interval of time.

Abstract: An elelctroacoustic transducer comprising a diaphragm provided with conductors and magnetic zones at both sides of the diaphragm (5) for producing an energizing field at the location of the conductors (6). At the boundary areas of the magnetic zones (1, 2; 2, 3; 3, 4) auxiliary fields are produced in order to reduce stray fields at the location of the boundary areas (1, 2; 2, 3; 3, 4). This results in a better concentration of the energizing magnetic fields in the plane of the diaphragm (5), so that a stronger magnetic field is obtained at the location of the conductors (6).

Abstract: A tobacco smoke filter plug comprises a fiber tow filling in the form of cylindrical element composed of an inner core phase (A) and an outer skin layer (B) having different fibrous arrangement structures. The inner core phase includes fibers which have been folded about an axis (D) making an angle (a) with respect to the longitudinal axis (C) of the filter plug, while the outer skin layer (B) includes fibers which have been folded about an axis substantially parallel to the longitudinal axis of the filter plug and at least partially surrounds the inner core phase (A). 
     The plug is produced by feeding a fiber tow through air jet means having a nozzle portion so that the tow is folded in a transverse direction to the longitudinal axis of the filter plug within a space in a tongue portion of a filter plug machine. The outer peripheral portion of the folded fiber tow is then drawn in a direction substantially opposite to the feed direction by air escaping from the end portion of the nozzle portion to form the outer skin layer (B), and a sheering stress is applied to the folded fiber tow in said space to form the core phase (A).
