Abstract: [PROBLEMS] The invention is to provide an aqueous one-component coating agent that is environmentally friendly and safe, and is excellent in productivity and storage stability, and also in alkali resistance and solvent resistance of a coated film. [MEANS FOR SOLVING PROBLEMS] The problems are solved by providing a method for producing polyurethane emulsion for an aqueous one-component coating agent, comprising: reacting an organic diisocyanate (a1), a high molecular weight polyol (a2) and a low molecular weight glycol containing a carboxyl group (a3) to produce an isocyanate-terminated urethane prepolymer having a carboxyl group (A); mixing the urethane prepolymer (A) with a polyisocyanate containing a nonionic polar group (B); neutralizing the carboxyl group in the system with a neutralizing agent (C); and subjecting the mixture to emulsification in water and chain extension with water or an amine.

Abstract: A mobile station typically determines whether to drop a communication link and/or a base transceiver station (BTS) based on a performance of an associated forward link. In order to avoid dropping a communication link that has a weak forward link but a strong reverse link, a communication system is provided that determines whether the reverse link is still good before determining to drop the communication link. In one embodiment, the communication system determines whether reverse link is still good based on a quality metric associated with the reverse link and quality metric(s) associated with one or more other reverse links that are in a soft-handoff mode with reverse link. In another embodiment, the communication system determines whether reverse link is still good by comparing a quality metric associated with the reverse link to a threshold.

Abstract: The need for reducing the time required for call setup in a wireless communication system (100) is addressed herein. A base station (BS 104) sends a channel assignment message to a mobile station (MS 102) and performs traffic channel initialization procedures with the MS. After completing the traffic channel initialization procedures, the BS sends a base station acknowledgment message to the MS and proceeds to transmit signaling to the MS without waiting to receive an MS acknowledgment in response to the base station acknowledgment message. Thus, the time normally taken to receive the MS acknowledgment is saved and call setup time reduced.

Abstract: A process for manufacturing cocoa which comprises kibbling the cocoa cake obtained by pressing cacao mass, pulverizing the kibbled cake into cocoa powder, which is fluidized by sending cooling air to it, and by maintaining the fluidized state thereof for a definite period of time, said cocoa powder is cooled to 18.degree.-30.degree. C., whereby the liquid fat contained therein is crystallized in the stable form as minute crystals.

Abstract: Improved granular cocoa which is sufficiently dense and stiff but nevertheless is readily soluble in water, even in cold water, can be produced without using any binder by subjecting a cocoa powder of which fat content is 12-29% to compression, feeding the compressed powder to a roller press thereby forming small plate-like agglomerates which are 0.5-3 mm thick, and crushing and sifting the agglomerates to obtain 10-30 mesh granules of cocoa. The physical properties of the cocoa granules are further improved by ageing the granules at temperatures below about 27.degree. C., most preferably at 15-25.degree. C., for a few hours to several days. the starting cocoa powder may have been added with powdered sugar and/or milk.
