摘要:
A polymeric metal complex capable of reversibly adsorbing oxygen to itself and desorbing oxygen therefrom, whose central metal is a low valency transition metal selected from the group consisting of metals belonging to Groups VIA, VIIA, VIII, IB and IIB of the fourth to the sixth periods of the periodic table; whose panar ligand is a chelate ligand selected from the group consisting of bi-, ter- and quadri-dentate monomeric ligands; and whose axial ligand is a polymeric ligand containing a functional group having a coordinating capacity. The subject polymeric metal complex is manufactured by the method which is characterized in that (A) a monomeric metal complex whose central metal is a low or high valency transition metal selected from the group consisting of metals belonging to Groups VIA, VIIA, VIII, IB and IIB of the fourth to the sixth periods of the periodic table and whose ligand is a chelate ligand of any of the bi-, ter- and quadri-dentate ligands is reacted with a polymeric ligand to replace the axial ligand of said monomeric metal complex by said polymeric ligand, or (B) the central metal of said monomeric metal complex is combined with the residual group of a polymeric compound to provide a .alpha. bond between carbon and metal, and that where the central metal of said monomeric metal complex is a high valency transition metal, then said central metal is reduced to a low valency state by a chemical reaction using a reducing agent or another form of reaction using an electrode before, after or simultaneously with the aforesaid reaction (A) or (B).
摘要:
A stator provided with annular split stator cores, formed by stacking steel plates. Each plate includes a yoke and a stator tooth. The cores include a yoke portion a stator tooth portion. The stator is manufactured by arranging an electromagnetic steel plate between a first die and a second die. The first die has a hole shaped as a steel plate. The second die has a projection inserted into the hole and shaped as a steel plate. The steel plates are formed by the first and the second dies. In a gap between an inner surface of the first die that defines the hole and an outer surface of the projection, a gap at a part that forms the stator tooth portion is larger than a gap at a part that defines a circumferential end surface of the yoke portion located in a circumferential direction of the stator core.

A stator provided with an annular stator core formed by annularly arranging split stator cores, and also with coils mounted to the stator core. The split stator cores each includes a yoke portion extending in a circumferential direction of the stator core and a stator tooth protruding from the yoke portion. On at least part of side surfaces of the stator tooth that are arranged in a circumferential direction of the stator core, a radial end surface of the stator tooth that is located radially inward of the stator core, and, of radial end surfaces of the yoke portion that are arranged in a radial direction of the stator core, the radial end surface at which the stator tooth is formed, a rough surface portion is formed having surface roughness greater than that of circumferential end surfaces of the yoke portion that are located in a circumferential direction of the stator core.

A novel nonvolatile memory element, which can be manufactured by a simple and high yield process by using an organic material and has a high on/off ratio, and a method for manufacturing such nonvolatile memory element. A switching layer (14) made of an electrical insulating radical polymer is provided between an anode layer (12) and a cathode layer (16). Further, a hole injection transport layer (13) is provided between the switching layer (14) and the anode layer (12), and an electron injection transport layer (15), between the switching layer (14) and the cathode layer (16). An intermediate layer is provided between the switching layer and the adjacent layer. The radical polymer is preferably nitroxide radical polymer. The switching layer (14), the hole injection transport layer (13) and the electron injection transport layer (15) are formed by being stacked by a wet process.

A hybrid vehicle is provided with a first transmission passage for transmitting driving force of an engine to driving wheels and a second transmission passage for transmitting driving force of a driving motor to the driving wheels, and driven by selectively using or in combination of the first transmission passage and the second transmission passage. The hybrid vehicle includes: a first input gear for inputting the driving force of the engine; a second input gear for inputting the driving force of the driving motor; and an idle gear meshed with the first input gear and the second input gear, and transmitting at least one of the driving force of the engine and the driving force of the driving motor toward the driving wheels. The driving force to be input from at least one of the first input gear and the second input gear is transmitted to the driving wheels via the idle gear and the final differential gears.

Tofu is automatically packed at high speed without damaging the tofu, and water is saved through elimination of the need for exposing the tofu to water. An automatic apparatus for packing tofu includes a pack-moving device 2 for conveying a pack P for tofu T, and a tofu-transporting device 3 disposed above the pack-moving device 2 and conveying cut tofu T having a packing size. Both the pack-moving device 2 and the tofu-transporting device 3 are used to move the tofu T and pack P in the same traveling direction, thereby placing the tofu T in a lower pack P from above.
