Abstract: An ultraviolet irradiation device includes a storage wall defining a space configured to store fluid, and a light source configured to simultaneously emit ultraviolet light and visible light into the space. The storage wall includes a first transmission portion which is formed thinner than other regions of the storage wall and is configured to transmit part of the visible light emitted from the light source to the space.

Abstract: A sterilization device includes: a reservoir, a supply port, an output port and a light source. The reservoir part includes a first half reservoir part having a substantially hemispherical shape and located on an upstream side in a flow direction of the fluid at the supply port, and a second half reservoir part having a substantially hemispherical shape and located on a downstream side in the flow direction. The supply port opens to the first half reservoir part. The output port opens to the second half reservoir part. When the supply port and the output port are projected on a virtual plane orthogonal to an extending direction of an inner surface of a supply channel connected to the reservoir part at the supply port, a center of gravity of the supply port and a center of gravity of the output port are separated from each other.

Abstract: A liquid cooling device that is capable of efficiently cooling a liquid in the inside of a liquid holding container, and a beverage forming device including the liquid cooling device are provided. The liquid cooling device includes the liquid holding container that has an open portion; a container mounting part on which the liquid holding container is to be mounted; an air passage; and an airflow generating unit. The air passage is located directly above the open portion (4b), and at least a part of an outer periphery of the air passage extends along a peripheral edge of the open portion (4b). The airflow generating unit generates, within the air passage, an airflow flowing along the air passage. A hole portion (33) that communicates with the open portion (4b) is provided in a lower surface of the air passage.

Abstract: A disc-shaped stirring element (100A) includes at least one projecting portion (102) at a position on a lower surface (103a) separated from a rotation center, the projecting portion (102) projecting toward a bottom surface (51a) of a stirring container (51), and an upper surface (103b) of the stirring element (100A) is planar.

Abstract: A heating control system which allows a plurality of heaters to heat an object without depending on a variation in characteristics among a plurality of heater power sources includes: a thermocouple which detects a temperature of an object to be heated; temperature control means that receives a target temperature and a current temperature, and carries out electric power control so that these temperatures match; electric current and voltage detecting means for detecting an electric power value and a current electric power; and target electric power calculating means that receives the electric power value, and calculates the target electric power by multiplying the electric power value by a given ratio. The temperature control means receives the target electric power and the current electric power, and carries out electric power control so that the current electric power matches the target electric power.

Abstract: In order to make a heating control system which allows a plurality of heaters to heat an object to be heated without depending on a variation in characteristics among a plurality of heater power sources, a heating control system of the present invention includes: a thermocouple (6M) which detects a temperature of an object to be heated; temperature control means (3M) and temperature control means (3S1); electric current and voltage detecting means (5M) for detecting an electric power value (Wm), and electric current and voltage detecting means (5S1) for detecting a current electric power (PVs1); and target electric power calculating means (1S1) for calculating a target electric power (SPs1). The temperature control means (3M) receives a target temperature (SPm) and a current temperature (PVm), and carries out electric power control so that the current temperature (PVm) matches the target temperature (SPm).
