Title: Air gap controlling system for linear motor
Inventor: KOBAYASHI NOBORUU
IPC: B60L13/06
Filed: 1991-07-26
Abstract: ABSTRACT OF THE DISCLOSURE       An air gap controlling system for a linear motor wherein a comparatively small air gap can be assured between a truck-carried element and a ground-mounted element to assure a high efficiency of the linear motor and construction for driving such ground-mounted element is simplified.  Driving means is provided on each truck for driving a truck-carried element of a linear motor to be displaced upwardly or downwardly to adjust an air gap between the truck-carried element and an opposing ground-mounted element which also constitutes the linear motor. and an aimed value of the air gap between the two elements is set in response to a running speed of a velocity of the truck and a truck position signal representative of a position of the truck.  At the first truck, the driving means is controlled so that the air gap may be equal to the air gap instruction value which is a rather high value.  An air gap aimed value is set similarly for each of the trucks succeeding to the first truck, but is corrected so that an air gap of a succeeding truck may be controlled to a low value so as to assure a high efficiency of the linear motor.

IPC: H05K7/20
Filed: 1991-11-06
Abstract: HEAT EXCHANGER FOR A SEALED CABINET A sealed cabinet is provided for housing heat generating electronic equipment. The sealed cabinet includes access doors which sealingly engage the cabinet in a closed position and a head space within the cabinet and above the doors for housing a heat exchanger. The heat exchanger includes longitudinal air channels, and transverse air channels, the channels formed by a stacked arrangement of longitudinal convoluted fins and transverse convoluted fins, each separated from the other by a heat conductive sheet. Outside air access to the heat exchanger is provided by louvered openings in opposite faces of the cabinet. The heat exchanger is sealed into the head space to keep outside air separated from air within the sealed cabinet. Fans force outside air through the longitudinal air channels and air within the sealed cabinet through the transverse air channels.

Title: Method of depositing optical oxide coatings at enhanced rates
Inventor: NADEL STEVEN J
IPC: C23C14/34
Filed: 1990-08-06
Abstract: A sputtering method is provided in which a substantially transparent target oxide film with predetermined optical properties is prepared having substantially the same degree of absorption per unit thickness as were the process practiced with pure oxygen gas as sole reactant, yet with a rate that is enhanced with respect to the method when oxygen gas is sole reactant. In practicing the inventive method, a target substrate is sputtered in a chamber while providing a source of reactive oxygen. The source of reactive oxygen has a reactivity in forming target oxide that is enhanced with respect to pure oxygen gas and includes nitrous oxide. Target oxide deposited on the substrate has an absorption per unit thickness that is substantially the same absorption per unit thickness as when pure oxygen gas is sole reactant. The deposition rate is preferably controlled by a value derived from plasma emission lines of oxygen atoms and target atoms.

Title: Process and apparatus for locating a predetermined point on a cassette tape
Inventor: PEREGO LUCIANO
IPC: G11B27/13
Filed: 1992-02-17
Abstract: In the described method and apparatus a leader, distributed between two winding hubs of a magnetic tape cassette, is first completely would onto one hub by means of a first motor.  Then, a second motor carries out a complete rewinding of the leader onto the second hub to enable an encoder to execute the counting of the overall length of the leader.  Subsequently the first motor is operated again to rewind the leader onto the first hub.  The encoder counts how much leader has been rewound on the first hub and causes the stoppage of the rewinding when the length of the rewound leader reaches a predetermined value.  The invention arranges a leader so that it may be partly extracted from the cassette and then cut into two equal pieces which will be spliced to the opposite ends of magnetic tape.

Abstract: 31,712-00 TITLE OF THE INVENTION              CHEMILUMINESCENT LIGHTING ELEMENT                  ABSTRACT OF THE INVENTION       The invention relates to a chemiluminescent device, which comprises a tube made of a flexible, light-transmitting and chemically stable material, closed at both of its ends, and which comprises at least two compartments which are filled with liquids which produce chemiluminescent light when mixed.  The tube contains, between the ends, an internal diaphragm or disk, which separates the tube into said compartments. The diaphragm or disk has approximately a flat circular shape, with a cross-section which is approximately rectangular in profile, and is placed transversely with respect to the axis of the tube.  The edge is in continuous contact with the interior of the wall of the tube.  The elasticity, the external diameters and the internal diameters of the tube and, the diameter and the thickness of the diaphragm are selected in such a manner that the diaphragm can be tilted by simple manual pressure against the external walls of the tube, which pressure imparts a tilting torque to said diaphragm or disk and allows mixing of the contents of the compartments.  The closure at both ends is a fusion of the side walls of the tube and each comprises an area lying in a substantially flat plane.  The tube has a Stiffness Modulus of less than about 700 mPa and a Tensile Strength greater than about 15 mPa.
