Abstract: Provided is a sample packing device for packing a sample with respect to a microchip for performing reaction of a micro component contained in the sample, the microchip at least including: a sample reservoir; a reaction reservoir; and a channel connected between the sample reservoir and the reaction reservoir, in which a package including a sample chamber packed in advance with the sample is mounted on the microchip so as to pack the sample in the sample chamber into the sample reservoir.

Abstract: A sample processing device for a microchip, including: a sample vessel for packing a sample therein; and a reaction vessel which is continuous with the sample vessel through a channel, and to which the sample is sequentially delivered to be packed and mixed therein, in which the sample is repeatedly delivered between the sample vessel and the reaction vessel through the channel so that the sample is stirred and mixed.

Abstract: For heating or cooling a sample contained in a vessel portion through a heat transfer member held in contact with the vessel portion, there is used the vessel portion, which has a part formed of an elastic member, expands and contracts for injection and discharge of the sample, is closed other than a connecting port with a channel connected to the vessel, and expands and contracts for injection and discharge of the sample. The vessel portion expands correspondingly to the injection when the sample is injected through an inflow path serving as the channel into the vessel portion contracting in a non-contacting state with the heat transfer member. A predetermined amount of sample is injected into the vessel portion so as to expand the vessel portion, and the vessel portion comes into contact with the heat transfer member. The vessel portion is heated or cooled through the heat transfer member.

Abstract: Compressed gas is supplied from above to a specimen vessel having an open top. Transfer channels to reaction vessels are provided under a microchip and transfer channels extending from the reaction vessels are provided on the microchip. Transfer element is provided outside the microchip so as to supply the compressed gas from a member (cover) holding the microchip.

Abstract: This invention relates to an automatic sewing machine exclusively used for sewing a zipper on a workpiece and its related art. The automatic sewing machine exclusively used for sewing a zipper on a workpiece comprises a sewing machine (10, 20) capable of at least sewing linearly, a drive device movable in two axes right angles to each other in a plane vertical to the movement direction of the needle (11, 21) of the sewing machine and a zipper setting device (12, 22) attached to said drive device for gripping said zipper (3) and workpiece (1) in a predetermined relationship.

Abstract: A method of and an apparatus for controlling the sewing rate in a sewing machine is disclosed that comprises a reciprocally and vertically movable needle, a motor for driving the needle and a throat plate on which a work is to be placed having a needle hole through which the needle moves reciprocally and vertically. The sewing machine is adapted to repeatedly perform a cycle in which the needle moves downwardly from the upper dead center to the bottom dead center passing through the needle hole and then upwardly from the bottom dead center to the upper dead center passing through the needle hole and the cycle is adapted to take place in such a manner that while the needle is below the throat plate the needle is moved at a rate higher than that at which the needle is moved while the needle is above the throat plate.
