A sheet feeding device has a feed roller with a plurality of large-diameter portions and a retard roller having a plurality of large-diameter portions alternately disposed with respect to the large-diameter portions of the feed roller. Originals are individually separated between the feed roller and the retard roller. The distance between the two rollers is automatically adjusted so that when a load caused by a separated sheet in a sheet feeding direction is large, the amount of overlap between the large-diameter portions of the two rollers is reduced, and when the load is small, the amount of overlap is increased. Thus, optimum separation is performed in accordance with the thickness of the sheet and the coefficient of friction of the surface of the sheet.

The present invention relates to a bracket which can mount different units to a vehicle body without the use of additional spacers or the like. The bracket has an offset support bolt so that upon the bracket being seated in a 180 degree reversed orientation, the bolt assumes a new position with respect to the vehicle body so that a different unit can be mounted using the same number of parts.

An electret transducer in which the electret material is an inorganic insulator sheet with electric charges in it and is juxtaposed to an electrode, and either the sheet or the electrode is mechanically deformable to change the distance between the two, thereby changing the electric charge induced in the electrode by the charged electret sheet. In a preferred form, the electret material comprises a multilayer sheet of insulating materials. The method of forming the transducer includes at least the steps of vapor-depositing a thin layer of inorganic material on a substrate and subjecting the exposed surface of the insulating material to a source of electric charge for a time sufficient to implant charges in the insulating material. If the insulating material is to be deformable, it should be deposited on a thin layer of metal which, in turn, has been deposited on a thicker substrate. A spacer layer of metal is deposited on top of the charged insulating material. Thereafter, selected areas of the substrate and of the spacer layer are chemically removed to leave the thin metal layer and the charged insulating material free of support except around the periphery of such open area. The ability of the insulating material to accept and hold a charge may be improved by depositing the insulating material as two separate layers of different materials, one immediately on top of the other.

Disclosed are: Au—Ag core-shell nanorod particles wherein a cationic surfactant such as CTAB is substituted by an other compound; and a method for producing the Au—Ag core-shell nanorod particles. Specifically disclosed are Au—Ag core-shell nanorod particles which are characterized in that each of the nanorod particles comprises a gold nanorod particle that serves as the core, a shell layer that covers the surface of the gold nanorod particle and is formed from silver, and a copolymer that adsorbs on the surface of the shell layer. The Au—Ag core-shell nanorod particles are also characterized in that the copolymer is a block copolymer or graft copolymer that is obtained by polymerizing at least a polymerizable monomer (A) that has a group represented by general formula (I). In the formula, Ra represents an alkylene group having 2-7 carbon atoms.

A semiconductor device has a satisfactory ohmic contact on a p-type principal surface tilting from a c-plane. The principal surface 13a of a p-type semiconductor region 13 extends along a plane tilting from a c-axis (axis ) of hexagonal group-III nitride. A metal layer 15 is deposited on the principal surface 13a of the p-type semiconductor region 13. The metal layer 15 and the p-type semiconductor region 13 are separated by an interface 17 such that the metal layer functions as a non-alloy electrode. Since the hexagonal group-III nitride contains gallium as a group-III element, the principal surface 13a comprising the hexagonal group-III nitride is more susceptible to oxidation compared to the c-plane of the hexagonal group-III nitride. The interface 17 avoids an increase in amount of oxide after the formation of the metal layer 15 for the electrode.

An automotive wheel that can prevent deformation of a back side opening edge of a wheel rim in a radial direction and reduce the weight of the wheel rim is proposed.Because the automotive wheel has a structure in which an annular rib section formed in a stepped manner at each of the inside and the outside and having a thinner wall thickness than the other part of a ledge section is circumferentially formed in the ledge section of the wheel rim, an effect of preventing the deformation of a back side opening edge of the wheel rim in a radial direction is improved by virtue of a shaping effect of the annular rib section, and a weight reduction effect can be provided in connection with the thinner wall thickness of the annular rib section.
