Abstract: A power supply system includes a system control unit, an auxiliary power supply, and an auxiliary-power-supply control unit. The system control unit and the auxiliary-power-supply control unit are configured such that information of at least one control unit of the system control unit and the auxiliary-power-supply control unit is able to be output to another control unit of the system control unit and the auxiliary-power-supply control unit. The at least one control unit is configured to output information indicating that an operation of the at least one control unit is stopped to the other control unit when the at least one control unit stops the operation of the at least one control unit.

Abstract: The disclosure provides a steering knuckle, which has good rigidity and reliability. The steering knuckle includes: a wheel support portion for supporting a wheel; a damper support portion for supporting a damper; and an arm portion for connecting the wheel support portion and the damper support portion. The damper support portion is cylindrical and has a mounting hole through which the damper is inserted, and the arm portion includes a pair of side walls connecting the damper support portion and the wheel support portion and a bottom wall connected between the side walls, and the bottom wall is connected with the side walls at the middle portion in the vertical direction of the side walls.

Abstract: A seat rubber mounted onto a suspension component including: an outer peripheral plate-shaped part extending along a receiving part of the suspension to receive a coil spring; an annular curving part defined by a radially inner portion of the outer peripheral plate-shaped part rising along a riser part of the suspension; a center projecting part inserted into a positioning hole of the suspension while being positioned inside the outer peripheral plate-shaped part and projecting from a distal end of the curving part toward its proximal end; an annular groove provided between the curving part and the center projecting part while receiving the riser part; and a flat-plate shaped reinforcing member embedded in the outer peripheral plate-shaped part around the riser part outwardly away from the curving part so as to disperse and transmit an input from the coil spring to the receiving part.

Abstract: A method of fabricating a diffraction grating comprises the steps of illuminating a first hyperbolic diffraction grating having a spatial frequency of f/2 with a spherical wave from a point light source to produce a diffracted ray, diffracting the diffracted ray from the first hyperbolic diffraction grating with second and third hyperbolic diffraction gratings having a spatial frequency of f, merging the diffracted rays from the first and second hyperbolic diffraction gratings on a photographic plate to record interference fringes. The point light source, the first, second and third diffraction gratings, and the photographic plate are disposed to satisfy the relationship ##EQU1## where d is the distance between the point light source and the first diffraction grating and c is the distance between the first diffraction grating and each of the second and third diffraction gratings and also the distance between each of the second and third diffraction gratings and the photographic plate.

Abstract: A composite for moldings having the high bending elastic modulus and the high bending strength, comprising a thermoplastic resin and a polymerizable monomer which is a multifunctional polymerizable monomer having an alicyclic strucure unit or a mixture consisting of a multifunctional polymerizable monomer having an alicyclic strucure unit and a monofunctional polymerizable monomer having at least two alicyclic structure units, is prepared by compounding them. Also, a composite for moldings having the high bending elastic modulus and the high bending strength, comprising a vinyl chloride resin, a (meth)acrylate monomer which is a multifunctional (meth)acrylate or a mixture consisting of a multifunctional (meth)acrylate and a monofunctional (meth)acrylate, and a polymerization initiator. The composite has good workability. Further, an unfluid precursor for moldings is prepared by heating the composite.

Abstract: An elastically deformable die includes two or more die members formed of materials exhibiting different degrees of elastic deformation under the same stress which are combined and arranged such that the elastic deformation thereof under the pressure received from a workpiece during a forming operation causes the surface of the die in contact with the workpiece to be formed to a prescribed configuration. In die forming the composite die is brought in contact with a surface of the workpiece, the die is elastically deformed at the surface of contact by the pressure received from the workpiece during the forming process, and the workpiece is formed to the prescribed configuration by this deformation.

Abstract: A method of die forming using an elastically deformable die is characterized by using a die provided in advance with a prescribed pattern of thickness variation, allowing the die to be elastically deformed by the pressure it receives from the material being formed during the forming operation, and forming the material to the configuration resulting from the deformation.

Abstract: A method for recognizing a given pattern in a known system of pattern which contains a group of known patterns corresponding to different reference oscillation frequencies in one-to-one relation. First, a given pattern is represented in terms of a physical system capable of causing a nonlinear oscillation at a frequency corresponding to the conception inherent to the given object. The physical system is then oscillated so that the oscillation of the physical system will converge at one frequency under entrainment effect, and the converged frequency is compared with the reference oscillation frequencies of known patterns for identification of the given pattern.
