A small vehicle has an engine mounted to a frame assembly. The engine is mounted by a plurality of engine mounts. The engine mounts are seven times stiffer in compression and tension than in shear. The engine mounts have a block of resilient material that separates a pair of plates. The block can be any shape but a rectangular parallelepiped is preferred. The engine mounts are mounted on cylinders defined with a center axis that extends through a center of gravity of the engine in a direction pa...

A fluorescent lamp ensures categorical color perception for surface colors of at least red, green, blue, yellow and white, while improving the luminous efficiency in scotopic vision and mesopic vision or in a wide visual field, wherein dominant radiation is obtained from a phosphor which has peak emission wavelength in a wavelength region from 530 to 580 nm and a region from 600 to 650 nm, flux ratio of a phosphor having peak emission wavelength in a wavelength region from 420 to 530 nm is set t...

A distance-measuring apparatus is formed of a photographic device formed of a pair of image-forming lenses and photosensor arrays for taking images of an object through the image-forming lenses, and a calculating device electrically connected to the photosensor arrays for calculating a distance to an object to be measured by two images of the object taken by the photographic device based on a triangulation principle. The calculating device calculates the distance to the object by an amount of sh...

In a distance detection method, a pair of image data representing a pattern of images is obtained by using a pair of image sensors for receiving optical images. Then, a detection target extracted from each of the image data is captured while sequentially shifting positions of divisions in respective groups of divisions from window part data corresponding to a visual field to provide combinations, each having a pair of divisions, and a correlation value is calculated between each pair of the divi...

A distance-measuring apparatus includes light-sensitive devices formed of optical sensor arrays disposed on image-forming surfaces of right and left image-forming lenses, respectively. The apparatus uses image data from the optical sensor arrays of the light-sensitive devices to determine the distance from an object such as a vehicle in front of the apparatus via a distance detection circuit and capable of detecting condensation or a foreign particle obscuring a cover glass or defective pixels i...

A punching apparatus used for high speed punching of holes in a workpiece, such as a ceramic green sheet, for use as a printed-circuit board. Upper and lower die blocks, stationary relative to each other, are provided, with punch pins fixed in two dimensions by multiple guides. A fluid passage is provided within the lower die block for providing gaseous lubrication and cleaning of the punch pin while in operation.

A distance measuring apparatus of the invention includes an arithmetic operation device which uses the degree of shift detected when the distance to a reference object is measured and a known distance to the reference object, to determine the difference between the offsets of image-forming positions on optical sensor arrays caused by a windshield present between a measuring object and the optical sensor arrays. The arithmetic operation device uses the difference between the offsets of the image-...

It is an object of the present invention to provide spherical metal particles having excellent monodispersity. The present invention relates to a method of manufacturing monodisperse spherical metal particles characterized by passing liquid metal through a porous membrane so as to disperse the resulting liquid metal particles in a continuous liquid phase.

A multi-axis laser machine in which the working efficiency can be improved even when machining positions in respective systems are different from each other. The positioning operation of a laser positioning unit for positioning an optical path of a laser beam in an axis and the positioning operation of another laser positioning unit for positioning another optical path of the laser beam in another axis are performed independently of each other. An arbitration unit monitors the laser positioning ...

An information processing apparatus having a plurality of CPUs has increased reliability. When one of storage devices suffers a fault, a corresponding control device indicates the fault to other control devices, so that all the control devices can recognize the fault. When either one of the CPUs has accessed the storage device, the control device indicates the occurrence of the fault to the CPU. Upon reception of the indication of the occurrence of the fault, the CPU changes the storage device f...
