Abstract: A purification apparatus includes an ultraviolet lamp (41) emitting an ultraviolet ray with a wavelength having ozone generating effect and an ultraviolet ray with a wavelength having sterilizing effect and an accommodator (43) accommodating the ultraviolet lamp (41) in an accommodation space thereinside. The accommodator (43) includes a transmission portion transmitting the ultraviolet ray with a wavelength having sterilizing effect. A gas supplied from an oxygen introducing portion (50) into the accommodation space contains oxygen. Thus, ozone is generated in the accommodation space due to the ozone generating effect of the ultraviolet ray emitted by the ultraviolet lamp (41). The ozone generated in the accommodation space is exhausted from an ozone exhausting portion (51).

Abstract: A combinatorial weighing apparatus has chutes for distributing articles selected and discharged by combinatorial weighing operation to prescribed discharge positions. At least one means is coupled to the chutes for distributing articles discharged from weighing hoppers in a plurality of directions. A plurality of timing hoppers are provided which are capable of temporarily storing the articles distributed by the distributing means. Article receiving means is disposed for receiving the articles which have passed through paths selected by control means. The timing hoppers may temporarily store the articles to reduce the speed at which the articles pass.
