Abstract: An optical information recording medium is provided with a plurality of information layers (2, 3), each of which has a sector structure in which a data area (8, 12) is divided in the circumferential direction by a sector address (9, 13). The positions of the sector addresses (9, 13) of the respective information layers (2, 3) coincide in the circumferential direction. This can prevent errors during reproduction caused by the effect of other information layers and stabilize recording characteristics, resulting in an increased recording capacity of a rewritable recording medium having a plurality of information layers with a sector structure.

Abstract: A motorized window blind includes a mounting frame stretched in a longitudinal direction, a blind screen including a mounted end mounted on the mounting frame, a liftable end opposite to the mounted end in a transverse direction relative to the longitudinal direction, and a flexible intermediate portion interposed therebetween. A motor has an output shaft and is mounted in the vicinity of the mounting frame so as to drive a drive transmitting member to move a distal end of the drive transmitting member in the transverse direction between retracted and extended positions where the distal end is proximate and distal to the mounting frame, respectively. A plurality of tubes are telescopically fitted to each other, and extend in the transverse direction.

Abstract: 2,4,6-trihydroxy-&agr;-p-methoxyphenylacetophenone (also identified herein as “D-58”), or its pharmaceutically acceptable derivatives such as salt and ester forms, is administered for inhibiting inflammatory reactions. The treatment can be remedial or prophylactic. Examples of the conditions that can be treated include acute inflammatory reactions and allergic inflammatory reactions, and specific examples include allergy, asthma, arthritis, psoriasis, skin sunburn, inflammatory pelvic disease, inflammatory bowel disease, urethritis, uvitis, senusitis, pneumonitis, encephalitis, meningitis, myocarditis, nephritis, osteomyelitis, myositis, hepatitis, gastritis, enteritis, dermatitis, gingivitis, appendicitis, pancreatitis, cholocystitis and cholangitis. The 2,4,6-trihydroxy-&agr;-p-methoxyphenylacetophenone can be administered by various routes as needed.

Abstract: A grit tank (1), the inside of which is partitioned into an upper chamber (2), intermediate chamber and lower chamber (5), the intermediate chamber being partitioned into a left intermediate chamber (3) and a right intermediate chamber (4), is connected to a transport pipe (16) via a discharge port (9) of the lower chamber (5). The intermediate chambers (3, 4) are respectively communicated with the upper chamber (2) and the lower chamber (5) via a left upper communicating port (6) and a right upper communicating port (10) and also via a left lower communicating port (8) and a right lower communicating port (12). The communicating ports are respectively provided with a left filling valve (7), right filling valve (11) and changeover type feed valve (13).
