Abstract: A catheter includes a shaft having a first lumen inside thereof, an expansion/contraction portion that is disposed on a distal end portion of the shaft and is expandable and contractible in a radial direction, and an actuation portion that expands and contracts the expansion/contraction portion. The expansion/contraction portion has a fixed portion fixed to the shaft, a sliding portion capable of sliding in a longitudinal direction of the shaft on an outer peripheral face of the shaft, and a suspension portion extending in the longitudinal direction of the shaft that connects the fixed portion with the sliding portion. When the sliding portion is slid toward the fixed portion by the actuation portion, the suspension portion expands in a radial direction of the shaft.

Abstract: There is disclosed a method of manufacturing a rotor for a dynamoelectric machine. The rotor includes a rotating shaft, a rotor core fixed on the rotating shaft, and a cooling fan fixed to an axial end face of the rotor core. The method includes the step of fixing the cooling fan to the axial end face of the rotor core by resistance welding. The method is characterized in that in the resistance welding, both a positive electrode and a negative electrode are first brought into contact with the cooling fan to have the cooling fan held between the axial end face of the rotor core and both the positive and negative electrodes, and then weld current is supplied to flow from the positive electrode to the negative electrode.

Abstract: A novel therapeutic and prophylactic agent for inflammatory bowel diseases and a method for treating inflammatory bowel diseases is provided. The agent comprises a 2-amino-1,3-propanediol derivative (e.g., 2-amino-2-[4-(3-benzyloxyphenylthio)-2-chlorophenyl]ethyl-1,3-propanediol hydrochloride) represented by the chemical formula (1) or a pharmaceutically acceptable salt or hydrate thereof: The agent is useful in the treatment or prevention of Crohn's disease, Crohn's disease in large intestine, intestinal Behcet's disease, ulcerative colitis, bleeding rectal ulcer and pouchitis.

Abstract: A shape of an inputted casting product is divided into a plurality of cells. A heat-transfer solidification of a molted metal is analyzed. A value of G/?{square root over (R)} (G: temperature gradient, R: cooling rate) is computed in each cell. A corresponding value, as a specific gravity value, corresponding to G/?{square root over (R)} in each cell is retrieved from a database unit to be assigned to each cell. Cells included in a region are stratified and counted with respect to each corresponding value. Each counted number is multiplied by each corresponding cell volume to obtain a volume. The volume is multiplied by each corresponding value to obtain a product. All the products corresponding to all the corresponding values within the region are summed up and then divided by a region volume to obtain a shrinkage porosity occurrence rate as a specific gravity value of the region.

Abstract: Imide compounds having a propioloyl group or pharmaceutically acceptable salts thereof which exhibit potent activities to inhibit the production of Interleukin 1-.beta. and also the production of Tumor Necrosis Factor .alpha.. These imide compounds are useful as a prophylactic or therapeutic agent for inhibiting the production of Interleukin 1-.beta. and the production of Tumor Necrosis Factor .alpha., typically for such diseases as chronic rheumatism, sepsis, ulcerative colitis, Crohn's disease and many other related diseases in which Interleukin 1-.beta. and/or Tumor Necrosis Factor .alpha. would participate.
