Abstract: A Koji production system including a culture area, an environment control device, a Koji container, a carrying-in lane, a Koji container moving device, and a control unit. The culture area is an area for culturing the Koji by storing a plurality of the Koji container in a predetermined position. The environment control device is configured to control a temperature and humidity in the culture area. The Koji container contains raw materials of Koji placed at a height of 1 cm to 10 cm, the raw materials comprising a mixture of soybeans and Koji mold. The carrying-in lane is configured to move the Koji container to the culture area.

Abstract: An object of the present invention is to obtain Koji having an enzyme titer equal to or higher than that based on conventional methods without contamination of putrefactive bacteria within 30 hours which is a very short Koji production time. The present invention provides a method for producing Koji for brewed foods, including the steps of: (1) obtaining pre-cultured seed Koji by pre-culturing Koji mold using a culture material with 500 g/L or less of bulk specific gravity, and (2) performing Koji production for 18 to 30 hours after inoculating the pre-cultured seed Koji into a protein raw material and/or a carbohydrate raw material.

Abstract: According to one aspect of the embodiment, a steam turbine power plant 10 is provided with a steam turbine system 20 which generates electricity by driving a steam turbine by the steam from a boiler 21 or the like which generates the steam by combustion heat, and a carbon dioxide recovery system 50 which recovers carbon dioxide contained in the combustion gas from the boiler 21 or the like. In the steam turbine system 20, part of the steam having performed the expansion work in a high-pressure turbine 22 is introduced into a back-pressure turbine 27. The steam introduced into the back-pressure turbine 27 performs the expansion work and partly supplied to the carbon dioxide recovery system 50 through a pipe 42 to heat an absorption liquid 90 in a regeneration tower 70.

Abstract: An explosion-proof porcelain housing for use in a gas-filled insulating apparatus, comprising a porcelain housing body, and a first and second films. The first film is made of a first insulating material having low hardness and high elasticity, and is bonded to an inner surface of the porcelain housing body. The second film is made of a second insulating material having high hardness and high mechanical strength, and is bonded to an inner surface of the first film. A process for producing such an explosion-proof porcelain housing is also disclosed.

Abstract: In a method of lining resins on an inner surface of a porcelain housing, the porcelain housing having a tapered shape is rotated about a rotation axis in such a manner that the rotation axis of a side having a larger inner diameter is inclined upward with respect to a horizontal line, and an inclination angle and/or a rotation number are controlled in accordance with an inner diameter of the porcelain housing corresponding to a nozzle position, and resins are sprayed or flowed on the inner surface of the porcelain housing from a nozzle during rotations of the porcelain housing.

Abstract: A hollow porcelain insulator including an elastic insulating layer having a tensile strength of at least 150 kg/cm.sup.2 and a thickness of at least 2 mm for improving an explosion preventing property.
