Title: Composite plastic film and greenhouse built therewith
Inventor: KUJIRAI MASAMI
IPC: A01G13/02
Filed: 1994-11-15
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed are a composite plastic film and a greenhouse constructed by using the same as a covering sheet spread over a framework capable of exhibiting improved temperature elevation-suppressing effect in summer and improved warm-keeping effect in winter.  The composite film has a double-layered structure consisting of a transparent or translucent thermoplastic resin film as the substrate and a transparent overlayer of a polymeric resin formed on one surface of the substrate film and these two layers are correlated each with the other in relation to two newly defined parameters including "the total heat volume", which is a product of the overall weight and the specific heat capacity of the film, and "the absorptivity of radiation heat" defined in terms of the decrease in the radiation temperature of sunlight by transmitting the film, the overlayer having the total heat volume not exceeding 10% of that of the substrate film and the absorptivity of radiation heat not exceeding 60% of that of the substrate film.

Title: Cubic metal oxide thin film epitaxially grown on silicon
Inventor: RAMESH RAMAMOORTHY
IPC: H01G7/06
Filed: 1993-07-13
Abstract: A method of forming crystalline metal oxide thin films on silicon and the resultant structure. A crystalline buffer layer (10) of yttria-stabilized zirconia is deposited on a silicon substate (12). A thin template layer (14) of an anisotropic perovskite such as bismuth titanate or yttria barium copper oxide is deposited on the buffer layer under conditions favoring c-axis oriented growth. A nominally cubic metal-oxide layer (16) is deposited on the template layer which facilitates its singly crystalline growth. The me-tal oxide, often a nominally cubic perovskite, may be a conductive electrode, a ferroelectric, a non-hysteretic dielectric, a piezoe-lectric, or other class of material.

Title: Multishaped beam direct radiating array antenna
Inventor: LO FORTI RAIMONDO
IPC: H01Q21/00
Filed: 1995-02-23
Abstract: Multishaped beam direct radiating array antenna, essentially constituted (Fig. 1) with a network on which high power beam forming sub-networks (3), are disposed; said network (2) is interposed between radiating elements (1) and RF power amplifiers (4). This antenna is in addition constituted with a traditional network in which power combiners (5), phase shifters (6) and interconnection lines (11) are at their turn positioned. The most significant feature essentially resides in the fact that, with the help of a high power beam forming network (2), suitably designed, the correct amplitude and phase values, at radiating elements (1) level, may be achieved without differentiating the RF power amplifier (4) output levels, thus keeping its efficiency as high as possible. One of the advantages this configuration presents is the possibility to utilise only one antenna in comparison of the previous techniques in which the same results were obtained utilising many radiating panels.      Though, this antenna configuration offers more simplicity, lower costs and a good reliability. The invention lies in the field of multishaped beam, antennas and finds its application specially in the space communications.

Title: Electrical smoking system for delivering flavors and method for making same
Inventor: COLINS ALFRED L
IPC: A24F40/46
Filed: 1993-09-10
Abstract: A smoking system (21) is provided in which a replaceable cigarette (23) containing tobacco flavor material is electrically heated by a set of electrical heater elements contained within a lighter (25) to evolve tobacco flavors or other components in vapor or aerosol form for delivery to a smoker. The cigarette (23) and lighter (25) are adapted to provide air flow patterns through the smoking system such that air flows transversely into the cigarette (23). Such patterns improve aerosol and flavor delivery to the smoker and reduce the condensation of residual heater-region vapor/aerosol in the smoking system.

Title: Fiber cable counter
Inventor: HOLDEN DOUGLAS R
IPC: G02B6/46
Filed: 1995-05-24
Abstract: With standard fiber optic telecommunication cables, in a loose tube style, in multiples of 12, it is often difficult to remember the exact location (fiber color and tube color) of a particular fiber within the cable. This Fiber Cable Counter allows the Fiber Splicing Technicians to quickly identify a particular fiber in a hand tool. As well if fiber cable counts are of a composite nature with more than one, fiber number one, within the cable, then this Fiber Cable Counter allows the Technician to re-set the fiber cable count and identify the actual fiber cable color and tube which is different than the sequential cable numbering.          This will allow Fiber Splicing Technicians to quickly and accurately identify the correct fiber within the cable sheath. It is also very useful to the Engineer to identify fiber complements he/she wishes to re-route within a cable to an alternate branch.

Title: Die-Casting of Metals with Dispersion of Solid Particles in Resulting Castings
Inventor: DUSABLON ANDRE
IPC: B22D17/02
Filed: 1995-07-10
Abstract: The invention provides a method of die-casting of metals,  with dispersion of predetermined quantities of solid  particles  in  resulting  metal  castings.  This  is achieved by inserting a cartridge into the runner system, which cartridge is normally sealed at both ends with foil and  contains  the  predetermined  quantity  of  the  solid particles. When molten metal is injected through the runner system and thus through the cartridge,  it entrains the solid particles therewith which are thereby intermixed with the molten metal and form the composite material of which the die-cast part is thus made. The cartridge is preferably formed of the same metal as the one used for the die-casting, so that it may then be recycled.
