  • Patent number: 9869181
    Abstract: A scroll expander includes a driving scroll body having a first axis line a driven scroll body having a second axis line shifted with respect to the first axis line, a bearing plate including two plates coupled to the driven scroll body and having the second axis line a cylindrical driving pin attached to the driving scroll body, and a cylindrical guide ring attached to the bearing plate and having an inner diameter larger than an outer diameter of the driving pin. The driving pin includes an outer circumferential surface in contact with an inner circumferential surface of the guide ring. A hard film including diamond-like carbon is formed on the outer circumferential surface of the driving pin. The inner circumferential surface of the guide ring includes a polymer resin material with self-lubricity.

  • Patent number: 9719510
    Abstract: A scroll expander includes: a driving scroll body having a first axis line as a rotary shaft line; a driven scroll body having, as a rotary shaft, a second axis line shifted with respect to the first axis line; a bearing plate having the second axis line as a rotary shaft; a cylindrical driving pin attached to the driving scroll body; and a cylindrical guide ring attached to the bearing plate and having an inner diameter larger than an outer diameter of the driving pin. Four driving pins are disposed on the circumference of a circle around the first axis line at an equal interval. Four guide rings are disposed on the circumference of a circle around the second axis line at the equal interval so as to correspond to the four driving pins.

  • Patent number: 9528394
    Abstract: Provided is a power generating apparatus including an evaporator configured to evaporate a working medium with a heating medium supplied from the outside of a working medium flow path, an expander to which a driven machine is connected and which is configured to convert expansion force of the evaporated working medium into rotational force to drive the driven machine, a condensing mechanism configured to condense the working medium discharged from the expander with a cooling medium supplied from the outside of the working medium flow path, the condensing mechanism having at least one heat exchanger pipe through which the working medium flows, a cooling water sprayer configured to spray cooling water as the cooling medium over the surface of one or a plurality of heat exchanger pipes of the at least one heat exchanger pipe, and a cooling fan configured to blow ambient air over the one or a plurality of heat exchanger pipes to evaporate cooling water attached to the surface of the one or a plurality of heat exc

  • Publication number: 20090081328
    Abstract: There is provided a technique for obtaining a high-quality fermented beverage, in particular, a beer taste beverage by using a non-wheat grain, for example, ungerminated corn, which is easily available and frequently used as a raw material for food and drink, without causing fermentation failure. The non-wheat grain is fractioned at least into a starch fraction and a protein fraction. The two fractions are separately treated with respective exogenous enzymes to obtain a saccharified starch and a protein decomposition product, which are used as raw materials for a mother solution for a fermentation step. In this way, a failure in a preparation step is overcome. Studies were made specifically on the blending ratio of the saccharified starch and the protein decomposition product thus separately prepared to determine a preferable blending ratio that does not cause fermentation failure in the fermentation step.

  • Publication number: 20090081327
    Abstract: The present invention is a method for producing a processed corn product characterized in that corn or a material obtained from corn is treated with a fluid under a low oxygen concentration at 170 to 200° C. The processed corn product produced by this manufacturing method can impart a superior flavor, body taste, and thickness to a beverage.

  • Publication number: 20080131555
    Abstract: An object of the invention is to provide fermented beverages, in particular, beer-taste ones that contain isoamyl acetate abundantly to assure high organoleptic appeal. The invention also provides a process for producing a fermented beverage by performing alcoholic fermentation of an aqueous liquid mixture comprising a feed containing a carbon source and optionally hop, as well as water, wherein a maize protein digest is incorporated as a nitrogen source in the feed either before or during alcoholic fermentation.
