Title: Method and device for preparing high- temperature superconductor coatings
Inventor: LASKA VLADIMIR L
IPC: H01L21/02
Filed: 1990-01-26
Abstract: The method and the device are used in the manufacture of hyperconductive microelectronic devices, telecommunication and power transmission lines. They ensure increased uniformity of the coating, improved quality and decreased power consumption by the process, while eliminating the need for cooling the crucibles. The method involves the consecutive feeding of the initial substances to a fixed electronic beam with constant characteristics. The duration of the single action of the beam on each initial substance is the function of the ratio of the lengths of the crucibles containing the initial substances. The device consists of: a vacuum chamber (1), a mobile holder (2) with crucibles (3),an axial or radial electron gun (5) and an electric drive (7). There is a mobile blind (9) in front of a pad (8) with a shifting mechanism (10) and a substrate holder (13).

Title: Improved method for making printed circuits
Inventor: LOWE JOHN M
IPC: H05K1/09
Filed: 1989-12-22
Abstract: 1523d ABSTRACT OF THE DISCLOSURE           Printed circuits are produced by screen printing or the like to deposit conductors, resistors, capacitors and insulators.  Crossover connections are made by covering the conducting portions to be crossed with an insulating material that serves as a base for a printed crossing conductor.  Exposed conductors, as for keyboards and compression connections, are protected from the development of high-resistance corrosion products by printing or overprinting them with an ink that deposits a carbon layer.  The method permits the use of rigid printed-circuit boards having crossed connections without requiring the use of a two-sided board.  The equivalent of multilayer boards can be achieved by printing repeated layers of conductors. components and insulators on the same side of the board, or by printing on two sides of a board. Interconnection between adjacent layers can be made as a part of the printing process.  Resistors can be printed by screening or otherwise depositing a controlled amount of a resistive ink.  Capacitors can be produced by printing conductive layers separated by insulating layers.  The process may produce printed-circuit boards containing resistors and capacitors without the necessity for inserting and wave-soldering components.  If such a board is to contain components in addition to those printed by the process of the present invention, a printed carbon layer can be used as a solder resist to protect printed conductors during the wave-soldering process, and to protect exposed contacts, as for keyboards, during wave-soldering and in use.  The process also permits the printing of a conducting layer as a shield against radio-frequency interference or as a ground place to provide electrical isolation of portions of a circuit from each other.  A method of making a printed circuit board comprises applying a first and second coating in a desired pattern to a substrate, the substrate (12) being disposed in a different relationship to coating apparatus used in applying a second coating fro the relationship in which it is disposed in applying the first coating.  Preferably a number of identical boards are printed on a substrate (12) from which they are subsequently separated.  The individual boards are positioned such that the same pattern may be applied when the substrate (12) is presented to coating means in any of a number of orientations each separated from the next by a fixed angle of rotation about an axis (A) at right angles to the substrate (12), the first coating being applied in one such orientation and the second after the screen and substrate respectively have been rotated in opposite directions, (C, B) each through 90°.

Title: Collapsible filter for a fluid power apparatus
Inventor: ISAKSON LARRY E
IPC: B60T13/12
Filed: 1990-04-30
Abstract: A fluid power apparatus (10) includes a power piston (40) dividing a working chamber (18) from a first chamber (16), the power piston (40) biased toward a rest position by a spring (17) and the piston (40) displaced by means of restricting fluid flow between the working chamber (18) and first chamber (16). In order to keep contaminants from entering the first chamber (16), a collapsible filter (80) is disposed about a piston rod (13) of the power piston (40), the filter (80) having at an end cap (88) with a central opening (91) through which extends the piston rod (13) and at an opposite end member (98) a flange (95) which0 serves as a seat (97) for the spring (17). The end member (98) seats sealingly against the power piston (40) while the end cap (88) has a sealing mechanism (92) about the periphery of the central opening (91) to provide sealing between the end cap (88) and input rod (13). If during operation of the fluid power apparatus (10) the end cap (88) should engage an opposite wall (15) of the first chamber (16), the filter (80) collapses and permits continued full stroke displacement of the power piston (40) without damage to the filter (80). Should the filter (80) become clogged, the spring (17) seated upon the flange (95) permits the flange (95) to lift away from the power piston (40) so that fluid may bypass the filter (80) and effect continued operation of the fluid power apparatus (10).

Abstract: ABSTRACT OF THE DISCLOSURE       A work surface is specially designed for use with a computer terminal by providing a separate and movable monitor support portion within the work surface movable relative to the work surface in a parallel manner for adjusting the height of the monitor support thereon.  With this arrangement, the end user may personalize the work surface according to her/his own requirements.  A number of work surfaces already have height adjustable keyboard support arrangements which recognize that the height for typing is separate and distinct from the normal work surface height for writing.  The present invention recognizes that the computer monitor, which is supported on a work surface, has its own preferred position which again is separate and distinct from the height of the work surface.  In this way, the end user may either lower or raise the computer monitor by means of adjusting the height of the computer monitor support and thereby customize her/his work environment to her/his own needs.
Patent CA-2017062-A1 (CA)
Inventor: NAKANO HIROTAMI
IPC: H02J3/34
Filed: 1990-05-17
Abstract: A switching power supply apparatus includes a high frequency switching power supply circuit (1) supplied with a direct current voltage from a direct current power source (E).  Switching elements (S1, S2) included in the high frequency switching power supply circuit alternately become conductive in response to a control pulse, whereby high frequency power is generated.  The high frequency power is transferred through an isolation barrier (45) formed of capacitors (C1, C2) to a frequency converting circuit (7) wherein the high frequency power is frequency-converted into direct current power and then supplied to a load circuit (4).  Accordingly, a conventionally used transformer is not required, so that no iron loss nor copper loss is generated in a isolation circuit (20), which allows the apparatus to be made more compact and lighter.
