Abstract: A foreign matter inspection system that is less likely to misidentify a crack as a foreign matter during an image inspection in which a vibration is applied to a powder contained in a bag-like container. The foreign matter inspection system includes a vibration device configured to apply a vibration to a container, a photography device configured to optically photograph the inside of the container through a transparent area, and a determination device configured to determine whether a foreign matter is present inside the container based on an image of the container photographed by the photography device. The vibration device alternately applies weak vibrations W and strong vibrations S to the container. The determination device determines whether the foreign matter is present inside the container based on the image of the container photographed by the photography device when the vibration device applies the weak vibrations W.

Abstract: This invention relates to a fish bait comprising a raw fish which has been ground and pulverized in micronized form, blended with a surface active agent, and the resulting mixture dried by a process which allows the pulverized bait to remain raw, such as by freeze-drying, pulverizing the dried bait again to a micronized form, and thereafter placing the dried and micronized bait into a water permeable container and sealing the same. When placed in the water, the bait thus manufactured, allows the taste and smell thereof to be dispersed throughout the water and thereby attracts a desired fish.
