Abstract: The present invention provides portable radio apparatus that keeps a good transmitting quality. In the invention, a receiving antenna is determined at reception from among transmitting/receiving antennas (12) and (14) on a per transmitting slot basis by way of the space diversity (16). Then, a determined result BRNC is output to a controller (18). The controller (18) outputs a control signal to a logic circuit (20) based on the determination result BRNC. The logic circuit (20) outputs switching signals (SUB 1) and (SUB 2) corresponding to the control signal to an antenna switching section (24), which selects a transmitting antenna. It is possible to select an antenna whose receiving quality is better at reception as a transmitting antenna in the next transmitting slot. This keeps the transmitting quality better. Switching between transmitting antennas is made on a per transmitting slot basis. This assures quick adaptive switchover to an antenna having a good transmitting quality.

Abstract: An embossed sheet which is excellent in embossing properties, whitening resistance and transparency, can be prepared by using a resin composition containing specific ratios of (A) polypropylene having a specific melting point of 125.degree. C. or higher, (B) ethylene-.alpha.-olefin copolymer having specific properties and (C) random copolymer of aromatic vinyl compound and conjugated diene compound having specific properties. Further, the present invention provides the laminates which is made using the above embossed sheet and the method for producing them.

Abstract: A process for producing a carboxylic acid ester which comprises reacting a hydroxy compound for example a primary or secondary alcohol, lankacidin C or maridomycin with a carboxylic anhydride in the presence of carboxylesterase as a catalyst in an organic solvent.

Abstract: A transfer sheet is here disclosed which is prepared by forming a highly glossy pattern layer of an ink containing a curable resin and silicon resin on the matte surface of a base sheet which is excellent in release characteristics to the thermosetting resin. In addition, a method for the preparation of a thermosetting resin decorative material is also disclosed which comprises the steps of superposing the above-mentioned transfer sheet on a resin-impregnated paper so that the pattern layer on the transfer sheet may be brought into contact with the resin-impregnated paper; then heating and pressing the resulting laminate; and after the curing of the resin in the resin-impregnated paper, releasing the transfer sheet therefrom.

Abstract: The compound of the formula: ##STR1## wherein R.sub.1 is hydrogen, methyl or hydroxymethyl, R.sub.2 is hydrogen or methoxy, R.sub.3 is hydroxy or methoxy, and R.sub.4 is hydrogen or a group ##STR2## is novel, and the compound is of use as inhibitors of animal tissue fibrosis, or biochemical reagents.

Abstract: The interseparating of desacetyl-cephalosporin C, desacetoxy-cephalosporin C and cephalosporin C can be accomplished by adsorbing these available cephalosporins on activated carbon and effecting a fractional elution thereof with water containing 0 to 20 percent (V/V) of an organic solvent or solvents.

Abstract: A laminated thermosetting decorative sheet has on its surface glossy protruding parts and matted recessed parts, and the recessed parts are preferably colored. This laminated thermosetting decorative sheet is manufactured using a press plate with an enamel layer having protruding parts whose enamel surfaces are matted.

Abstract: Inosine and/or guanosine can be separated from fermentation broth containing microbial cells and high-molecular-weight substances by heat-treating said broth at 90.degree. to 110.degree. C., followed by subjecting to ultrafiltration. The present process is advantageously carried out in the industrial use of ultrafiltration.

Abstract: An antifibrotic substance P-1894B is produced by cultivating a microorganism belonging to the genus Streptomyces and being capable of producing P-1894B in a culture medium to have Antifibrotic substance P-1894B elaborated and accumulated in the cultured broth and recovering the substance.P-1894B is effective for the prophylaxis or treatment of the fibrosis due to excessive collagen accumulation in mammal.
