A liquid transfer apparatus comprises a liquid containing section for containing liquid, a liquid introducing section for introducing liquid into the liquid containing section and a liquid leading out section for leading out the liquid introduced into the liquid containing section. When a number of such liquid transfer apparatuses are connected together, the liquid introducing section and the liquid leading out section of such liquid transfer apparatus are arranged such that the liquid leading out section of a liquid transfer apparatus communicates with the liquid introducing section of another liquid transfer apparatus.

A process for producing a mass transfer device is provided which enables packing of a packing material uniformly in a flow channel, and transfers a specified substance by flowing a fluid containing the specified substance through a flow channel on a substrate. A mass transfer device produced by the process is also provided. The process for producing a mass transfer device comprises steps of preparing a substrate, forming a flow channel on the surface of the substrate, applying a liquid drop composed of a packing material and a liquid medium, and packing the packing material in the flow channel by removing the liquid medium.

An Nd-Ba-Cu-O bulk superconductor includes oxide including metallic elements of neodymium (Nd), barium (Ba) and copper (Cu), and has a structure in which fine particles of Nd.sub.4 Ba.sub.2 Cu.sub.2 O.sub.10 (i.e., Nd422) are dispersed uniformly in crystalline grains of NdBa.sub.2 Cu.sub.3 O.sub.x (i.e., Nd123). It is produced by preparing a mixture powder in which an Nd123 powder and an Nd422 powder are present uniformly, thermally treating the mixture powder in a temperature range where the Nd123 powder melts partially at least but the Nd422 powder hardly melts, and gradually cooling the partially melted mixture powder in a temperature range around a solidifying point of the Nd123 powder. It exhibits an enhanced magnetic-field-trapping capability in the regions of low magnetic field, because of the pinning effect resulting from the fine particles of Nd422 dispersed uniformly in the crystalline grains of Nd123.

C. in the atmosphere.
摘要:
A parking brake foot pedal is pivoted to a bracket, and is formed with a ratchet plate portion. A pawl is engaged with the ratchet so as to hold the parking brake in the applied condition. A release lever is pivoted to the bracket so that it displaces the pawl away from the ratchet when it is pulled by a release structure. A resin bush is attached to the release lever at a position remote from its pivoting point. The bush has a hole through it which is narrowest at its middle portion and opens out towards its ends. A release cable passes through this hole in the bush, and on its end there is fixed a stop member larger than the internal diameter of the hole in the bush. Thereby, the end of the release cable is flexibly coupled to the release lever, so as not to be subject to severe bending stress when the release cable is pulled and rotates the release lever so as to displace the pawl away from the ratchet and release the application of the parking brake.

The barium oxide acts as a catalyst and exerts a function of completely burning an organic binder at a temperature lower than about 400.degree. C. where the reaction between the organic binder and zinc oxide is not substantially advanced.
