Abstract: A method for operating a food processing apparatus is provided. The food processing apparatus includes a reaction vessel that has a space that accumulates a liquid reactant used for a food product; a catalytic reactor that includes a reaction tube and a light source; and an introducing tube for introducing the reactant into the reaction vessel. The reaction tube has an outer surface where a photocatalyst is provided. The reaction tube transmits light. The light source generates heat at a time of light emission in which the light source emits light from an inner side of the reaction tube. The method for operating the food processing apparatus includes introducing the reactant into the reaction vessel from the introducing tube. In the introducing, the reactant is introduced up to a position at which a liquid surface of the reactant is positioned higher than an opening portion of the introducing tube.

Abstract: Provided are a stock solution concentrating device, a stock solution treatment device and a circulation-type treatment device that can prevent the deposition of cells and the like on a filtration member and that can continuously filter and concentrate a stock solution such as pleural and ascitic fluid or blood plasma. The stock solution concentrating device concentrates a stock solution such as pleural and ascitic fluid or blood plasma to form a concentrated solution, and is equipped with: a filter (10) having a filtration member that filters the stock solution; a concentrator (20) to which the filtrate which has been filtered is supplied, and which concentrates the filtrate to form a concentrated solution; and a stock solution supply unit that supplies the stock solution to the filter (10). The stock solution supply unit has a supply amount adjustment function for adjusting the amount of the stock solution supplied to the filter.

Abstract: Disclosed is an apparatus for automatically taking off inspected hose from a pattern plate of a hose-inspecting apparatus and fitting them on a pattern plate of a hose-finishing apparatus, to be disposed in the middle of where each one of the inspecting pattern plates and each one of the finishing pattern plates are opposed at a certain interval. The hose-fitting apparatus is constructed substantially of a finger and a pair of levers that serve to make the finger ascend and descend with its position kept upright along a certain eldless track pierced through a pair of plates on both sides of it by means of a pair of belts respectively provided to the plates and a driving means. Thus, in the ascending progress close to the inspecting pattern plate, the finger can remove a pair of hose from it upward getting in from its bottom and, in the descending progress close to the finishing plate, put the hose on it getting out therefrom repeatedly.
