  • Publication number: 20210040424
    Abstract: Provided is a method for manufacturing a long-life brewed alcoholic beverage by a filtration process with the use of a porous membrane involving a washing step, whereby a high tolerance (chemical tolerance) to a washing solution (a chemical solution) and a good filtration performance are achieved. A method for ma manufacturing a second brewed alcoholic beverage which includes: a filtration step for passing a first brewed alcoholic beverage, which contains a yeast and a high-molecular substance or sediment component produced through fermentation by the yeast, through a porous membrane, which is formed of a resin having a three-dimensional network structure, to thereby separate the second brewed alcoholic beverage from the yeast; and a washing step for passing a washing solution through the porous membrane or immersing the porous membrane in the washing solution to thereby wash the inside of the porous membrane.

  • Patent number: 7746666
    Abstract: A shield case is fixed to a surface of a circuit board with a conductive joining material so as to cover a shielded portion on the circuit board surface. The shield case includes joint terminals extending outward and inclined upward from a lower edge thereof that is in contact with the circuit board surface. The joint terminals are joined to the circuit board surface with the conductive joining material provided therebetween. The shield case can thereby be fixed to the circuit board surface, and grounded to a ground portion provided on the circuit board.

  • Publication number: 20020050349
    Abstract: A heater/cooler unit of an automotive air conditioning system, comprises a casing, an evaporator, a heater unit and at least one duct. The casing has air inlet and outlet openings which are connected through an air flow passage defined by the casing. The casing includes an enlarged portion and a reduced portion by which an enlarged part and a reduced part of the air flow passage are defined respectively. The casing thus has a concave contour defined by the reduced portion thereof. The evaporator is installed in the enlarged part of the air flow passage. The heater unit which is smaller in size than the evaporator is installed in the reduced part of the air flow passage. The duct snugly extends along the concave contour of the casing. The duct has one end connected to a downstream portion of the air flow passage.

  • Patent number: 5715705
    Abstract: An evaporator/expansion valve unit for use in an automotive air conditioning system, comprises an evaporator which includes first and second parallely extending elongate tanks and a plurality of flat hollow elements mounted on the first and second elongate tanks. The interior of each element is in a fluid communication with the interior of each tank. The first tank is formed with inlet and outlet openings. A block type expansion valve has a first passage which is closed when a spherical valve body abuts against a given part of the first passage against a certain force applied thereto and a second passage which has a temperature sensing means by which the certain force is varied in accordance with the temperature of a refrigerant flowing in the second passage. The first passage has an outlet opening connected to the inlet opening of the first tank. The second passage has an inlet opening connected to the outlet opening of the first tank. The expansion valve has the first tank directly mounted thereon.
