Abstract: In a bathroom ventilating air-conditioning system including a first air inlet open to a bathroom; a main body conditioning air drawn in from the first air inlet; and a first air outlet open to the bathroom, where the air is circulated in the bathroom and the main body to air-condition the bathroom, the main body is placed in an indoor space other than on the ceiling surface of the bathroom; the first air inlet is connected to the main body through a first air inlet duct; and the main body is connected to the first air outlet through a first circulating duct.

Abstract: Problem: To provide a microorganism with an ability to produce deoxy polyol dehydrogenase. Means for Resolution: A microorganism belonging to genus Enterobacter with an ability to produce a dehydrogenase for deoxy polyol of the same structure at the positions C2 and C3 as that of ribitol or L-iditol. The bacterial cell IK7 of the genus Enterobacter (accession No. NITE P-271). A method for producing deoxy ketose comprising allowing a culture containing the deoxy polyol dehydrogenase obtained by the culturing of the microorganism of the invention or allowing the deoxy polyol dehydrogenase to react with a solution containing deoxy polyol of the same structure at the positions C2 and C3 as that of ribitol or L-iditol to oxidize deoxy polyol to produce the corresponding deoxy ketose and then collecting the deoxy ketose. The deoxy polyol is 1-deoxy-D-allitol, while the corresponding deoxy ketose is 1-deoxy-L-psicose.

Abstract: Providing 1- or 6-deoxy products corresponding to all of aldohexoses, ketohexoses and sugar alcohols, as based on Deoxy-Izumoring, as well as a method for systematically producing those products. A method for producing deoxyketohexose and a derivative thereof using a deoxyketohexose isomerase derived from Pseudomonas cichorii ST-24 (FERM BP-2736), comprising epimerizing 1-deoxy D-ketohexose or 6-deoxy D-ketohexose or 1-deoxy L-ketohexose or 6-deoxy L-ketohexose at position 3 to produce the individually corresponding 1-deoxy D-ketohexose or 6-deoxy D-ketohexose or 1-deoxy L-ketohexose or 6-deoxy L-ketohexose as an intended product.

Abstract: Object: To provide a thermostable L-ribose isomerase. Means for Resolution: The thermostable L-ribose isomerase with MW. 32,000 (by SDS-PAGE), optimal temperature of 45° C., optimal pH of pH 9.0 (glycine-NaOH buffer), and stable physicochemical properties such as temperature stability up to 45° C. during thermal treatment at pH 9.0 for 10 minutes, and with an action to isomerize L-ribose to generate L-ribulose or of inversely to isomerize L-ribulose to generate L-ribose.

Abstract: There is provided a blow out grill including a duct connecting port communicated with a duct, an indoors-side opening communicated with inside of a room, a panel base portion forming a wind blowing path of carried air between the indoors side opening and an outdoors-side opening, a panel portion formed to be opposed to the panel base portion, and a blow out port communicating with the wind blowing path and formed between the panel portion and the panel base portion forming a second rib directed to a side of the panel portion at the panel base portion and forming a first rib directed to a side of the panel base portion at the panel portion. The blow out grill does not deteriorate in view of a room, is easy to clean and inexpensive and simultaneously prevents contamination of the installing face and a cold draft.

In this way, there can be realized a blow out grill which does not deteriorate an outlook of the room, and is excellent in cleaning performance and inexpensive while simultaneously preventing contamination of an installing face of the blow out grill and an unpleasant feeling by draft cold.
