Abstract: A liquid food composition that can be conveniently ingested or given with a tube and contains reduced aggregates in the composition is provided. A liquid food composition that shows fluidity in the neutral region, but solidifies in the stomach environment is further provided. According to the production method of the present invention, generation of fine particles in the production process of a liquid food composition containing a divalent metal salt, a protein, and water-soluble dietary fibers is reduced. Therefore, emulsification stability of the composition is improved, clogging of aggregates in strainer disposed in the production line etc. are eliminated, and thus the composition can be efficiently produced.

Abstract: A medical device for body cavity which has a main stent body and a sheet-shaped member having an opening and covering at least a part of the main stent body as described above. It is desirable that, when the main stent body is dilated from the first diameter in the compressed state to the second diameter, the above-described sheet-shaped member spreads so as to cover at least a part of the main stent body without restricting the movement of the main stent body toward the circumferential direction while the shape of the opening of the above-described sheet-shaped member is retained even after the dilation of the main stent body. The above-described medical device for body cavity is applied to a delivery system which has a first catheter for transporting the medical device for body cavity into the body. In this delivery system, the above-described medical device for body cavity is located at the front end of the first catheter as described above so as to allow indwelling thereof.

Abstract: In a membrane treatment method, raw liquid is supplied to a circulation tank, and circulation liquid is supplied into an inter-membrane passage between filtration membranes disposed within a membrane apparatus, which is disposed separately from the circulation tank. Filtrate is obtained from the circulation liquid within the inter-membrane passages via the filtration membranes, and the circulation liquid is circulated by a circulation pump disposed between the circulation tank and the membrane apparatus, while returning the remaining circulation liquid to the circulation tank. A portion of the circulation liquid overflows from the circulation tank. A membrane treatment apparatus comprises a membrane apparatus, a circulation tank, and a circulation pump. The membrane apparatus includes filtration membranes disposed to form an inter-membrane passage between the filtration membranes. The membrane apparatus takes out filtrate from circulation liquid in the inter-membrane passage.

Abstract: A membrane apparatus includes a bubble supplying portion for supplying micro bubbles which is provided at a location in the vicinity of the entrance of a flow passage for raw liquid. Thus, the growth of a gel layer on a membrane surface can be prevented, and a large filtering amount can be maintained while preventing sludge from blocking the membrane. Moreover, since bubbles uniformly pass through the inter-membrane passages, sludge blocking can be evenly prevented over the entire surface of the membrane. When a flat membrane is used as the filtering membrane, there is provided an advantage of reducing the frequency of work for disassembling the frame and cleaning the membranes. A membrane treatment apparatus includes the membrane apparatus, an aeration apparatus, a circulating tank, and a filtrate pump.
