Title: Production of noodle
Inventor: HAYASHI SHIROU
IPC: A23L7/109
Filed: 1984-06-26
Abstract: PURPOSE:A fibrous material obtained from citrous fruits is added, when noodles are produced, the water can be increased to improve the extensibility, boiling yield, thus giving yellow noodles of good texture and flavor. CONSTITUTION:When noodles are made, a fibrous material from citrous fruits is added to the starting materials such as wheat fluor to give the objective noodles. The fibrous material is obtained by dipping the squeezing residue of each citrous fruit in 1% slaked lime suspension to coagulate pectin, squeezing and grinding the residue together with 1% caustic soda solution, finally washing the squeeze residue with water, followed by neutralization and vacuum drying. Since the resultant fibrous material is porous, it shows higher adsorption of water and water-soluble substances and its addition to the noodle materials such as wheat flour can increase the amount of water to be added, resulting in improved extensibility of the paste for noodles.

Title: Refrigerating air conditioning apparatus
Inventor: ENDO KAZUHIRO
IPC: F25B39/02
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To improve the lowering of heat exchange performance of an evaporator attributed to uneven distribution of a refrigerant by arranging a section reduced passage part in the course of a refrigerant paths divided in a plurality of an evaporator and a refrigerant path communication passage to make the passage part communicate with a passage bottom part in the course of another refrigerant path with a refrigerant position head smaller than that of the passage part. SOLUTION: A refrigerant passage 17 having a section reduced passage part communicates with a bottom part of a refrigerant passage 18 having a refrigerant position head thereof smaller than that thereof, that is, less in height than that by a refrigerant path communication passage 19. When the flow rate is low, a liquid refrigerant is supplied to an upper refrigerant path of an evaporator through which the refrigerant becomes harder to flow from a lower refrigerant path through the refrigerant path communication passage 19.  As a result, the pressure in the section reduced pipe part 51 of the upper refrigerant path falls below the pressure in a pipe through which a refrigerant of two phases, gas and liquid phases, of a lower refrigerant path flows 52 so that the communication pipe 19 sucks the liquid refrigerant in a heat exchanger tube 52 of the lower refrigerant path against a position head difference thereby improving the heat exchange performance of the evaporator.
