Title: Chemical vapor deposition process to replicate the finish and figure of preshaped structures
IPC: C23C16/32
Filed: 1990-10-09
Abstract: ABSTRACT OF THE DISCLOSURE    A process is disclosed by which the finish and/or figure of polished preshaped structures (such as mirrors) can be replicated directly by chemical vapor deposition, with only minor polishing of the replica being required to obtain a final product, and with the original substrate being reusable for further replication.  Relevant conditions under which the process can be carried out are given.  Featured in the process is a pretreatment step prior to the deposition of a layer of silicon carbide to form the replica, which pretreatment step involves the formation on the polished substrate of an oxide layer and a carbon layer of high finish and uniform thickness.  The carbon layer allows easy separation of the substrate and replica which otherwise would be bound together.

Title: Tunnel junction device composed of compound oxide superconductor material and method for fabricating the same
Inventor: ITOZAKI HIDEO
IPC: H01L39/24
Filed: 1990-11-27
Abstract: A tunnel junction device includes a pair of superconduction layers formed of a compound oxide superconductor material and a non-superconduction layer formed between the pair of superconduction layers. The non-superconductive material layer is formed of a compound oxide superconductor material which is substantially the same as that of the first and second superconduction layers but which is doped with a dopant of an amount sufficient for the compound oxide superconductor material to lose the superconduction property. The first superconduction layer, the non-superconductive material layer and the second superconduction layer have a continuous crystal lattice as a whole.     The above mentioned tunnel junction structure is formed by continuously depositing the compound oxide superconductor material on a substrate without interrupt of deposition from a beginning of the deposition of the first superconduction layer until a termination of deposition of the second superconduction layers, and adding a dopant concurrently with deposition of the compound oxide superconductor material only at the time of forming the non-superconduction layer, so that the first superconduction layer, the non-superconduction layer and the second superconduction layer are continuously formed in the named order without interrupt of deposition of the compound oxide superconductor material.

IPC: F24F3/14
Filed: 1991-08-30
Abstract: - i -METHOD OF AND APPARATUS FOR REDUCING THE        HEAT LOAD ON ENCLOSURE         ABSTRACT A method for controlling the condition of air in an enclosure, such as a greenhouse, containing growing plants involves reducing the heat load on the enclosure by reducing the rate of convective heat flow of air across the canopy of the plants.  This is achieved by heating and dehumidifying the air in the greenhouse during periods of low light levels such as at night in a manner that minimizes the need for ventilation for controlling humidity.     Apparatus  is  also  provided  for  controlling  the condition of air in an enclosure using an air-brine-vapor direct contact heat exchanger.   Regeneration of the brine from the heat exchanger can be achieved by heating the brine using heated air from the enclosure or hot flue gases such that latent heat and/or sensible heat contained in the air, gases,  and/or  vapor  exiting  the  regenerator  can  be transferred to the sir in the enclosure.
