  • Patent number: 6904767
    Abstract: An improved air conditioner system for controlling a desired temperature and a reduced humidity level in a space to be environmentally controlled, that comprises an additional second heat exchanger in the separate indoor air flow path. The refrigerant circuit includes an anti-migration control device between the compressor and the second heat exchanger. An anti-floodback control device is located upstream of the compressor between the first heat exchanger in the indoor air path and the compressor. An expansion control device is also located in the refrigerant circuit between the heat exchanger in the outdoor air flow path and the heat exchanger in the indoor air flow path. The second heat exchanger effectively becomes a hot gas re-heat de-superheater heat exchanger. The system enhances the latent capacity for providing dehumidified air of from 25–40 percent.

  • Patent number: 6875821
    Abstract: A process for making poly(hydroxystyrene)s whose phenolic hydroxyl groups are partially protected by acid-decomposable or -eliminable groups, by which the degree of deblocking of the phenolic hydroxyl groups is controlled. Namely, the production of a polymer containing, in the molecule, repeating units of the general formula (IA) and those of the general formula (IB), comprising adding an acid to polymer (B) containing in the molecule repeating units of general formula (II) in an organic solvent with the molar ratio of the acid to the OR3 group being 0.0001 equivalent or above but below 0.05 equivalent, and reacting the polymer with the acid. In the general formulae, R1 is hydrogen or methyl; R2 is C1-6 alkyl; R3 is an acid-decomposable or -eliminable group; R4 is hydrogen or a group derived from R3 by decomposition with acid; and p is 0, 1, or 2, with the proviso that the IB/IA molar ratio ranges 98/2 to 30/70.

  • Patent number: 6857735
    Abstract: A color image transfer method includes performing solid printing of an image portion on a hydrophilic transfer sheet coated with a water-soluble resin with an aqueous solution ink containing a component that dissolves the resin and imparts the resin with an adhesive property for a desired time by use of an ink jet printer, scattering heat-bondable resin powder onto the solid printed portion and fixing it thereto while removing the powder from portions other than the image portion, printing with a sublimation ink so that the image may be in register with the solid-printed image, superimposing the image surface on an article to be transferred and heat pressing, and peeling off the transfer sheet from the article to be transferred by giving moisture to the transfer sheet. The method enables single-part production of articles for full color image printing and can transfer only an image portion as in screen printing.

  • Patent number: 6778061
    Abstract: A fuse that can be made small while improving its breaking performance. An element 3 is securely held between the two lengthwise ends of a tubular fuse casing 2 and a pair of metal plates 4 having a melting point of more than 1000° C. The ends of the fuse casing 5 are respectively pushed into caps 5 so that the caps are fitted to the fuse casing 2 in such a manner as to cover the metal plates 4. The metal plates 4 protect the caps 5 from direct exposure to an arc discharge, which occurs when the element 3 fuses due to an overcurrent. Even if the fuse casing is made small, the metal plates 4 reliably interrupt overcurrent by absorbing the energy of an arc discharge.

  • Patent number: 6772519
    Abstract: The invention is a system and associated connection fitting for connecting a refrigerated line or air conditioning hose to the compressor unit or component on one end and the evaporator unit or component on the other end of a residential or commercial air conditioning or refrigeration system. The hose will be of a construction, which as well as having a relatively high bursting strength, will also not allow the refrigerant to permeate through the hose and escape into the outside environment. The associated connecting fitting allows the hose to be connected to the compressor/evaporator unit. The mounting surface of the fitting will allow it to either slide over or fit into the corresponding fitting on the compressor and/or evaporator unit. The opposite end, which shall connect to the hose assembly, will have flanges and “O” rings which when clamped will provide a secure connection as well as prevent loss of refrigeration.
