Abstract: A transfer apparatus transfers tablets ejected from a tableting machine to a container. The transfer apparatus includes a first chute, a cloth chute which serves as a buffer disposed at one end of the first chute, a winding apparatus for lifting the free end of the cloth chute, a bucket for receiving the tablets from the cloth chute, and a swiveling lift for moving the bucket. Because the formed pieces are not transported directly from the first chute to the bucket, but are first received within the buffer and then transported to the container, occurrence of cracking or chipping of the formed pieces can be prevented and high quality can also be maintained through minimizing the impact on the formed pieces which would otherwise occur during transporting.

Abstract: The present invention relates to a novel potassium channel protein expressed exclusively in the brain, a gene encoding this protein, a vector containing this gene, a host cell containing this vector, and so on. A typical method for obtaining the potassium channel protein of the present invention; mRNA is extracted from human cells or tissue capable of producing the potassium channel protein of the present invention. Then use is made of two primers between which the channel protein mRNA or a part of the mRNA region is located by using the thus extracted mRNA as a template. By carrying out a reverse transcriptase-polymerase chain reaction (to be referred to as RT-PCR hereinafter), the channel protein cDNA or a part thereof can be obtained. Thereafter, the channel protein can be produced by integrating the thus obtained novel potassium channel cDNA or a part of the same into an appropriate expression vector and then effecting its expression in a host cell.
