摘要： In a spectrographic type spectrometry measuring apparatus employing a concave holographic diffraction grating or a replica thereof, a small-size and light-weight spectrometry measuring apparatus having a high reliability with a spectrum position does not move in a photo detector plane in spite of an occurrence of a temperature change. This measuring apparatus is composed of a light-condensing device, a concave holographic diffraction grating or a replica thereof, and a telecentric correction lens for condensing a diffracted light from the diffraction grating telecentrically on the spectrum condensing plane. In this constitution, the spectral ray enters vertically to the spectrum focusing plane, and if the photo detector is moved in the optical axis direction due to a temperature change, the spectrum is not moved on the photo detector surface, and it is not necessary to calibrate an optical element due to an ambient temperature change.

摘要： A vehicle rear suspension system having a vertically swingable arm connected at the front end swingably to the vehicle body and secured at the rear end to a wheel carrying member which carries a rear wheel for rotation. Three lateral links ar provided and have inward ends pivotably connected to the vehicle body and outward ends pivotably connected to the wheel carrying member. The points of connection of the three lateral links to the wheel carrying member are not aligned in a straight line so that the orientation of the wheel carrying member can appropriately be controlled under bump and rebouncing movements of the rear wheel and under side and longitudinal forces acting on the rear wheel.

摘要： In an measuring method for optical transfer function of the invention, irradiating-light from a light source (31) scans an element to be measured within an image sensor of an imaging camera constituted by integrating an imaging optical system and the image sensor. The element to be measured converts sequentially the irradiating-light into an electrical signal and outputs the electrical signal. Further, based on the outputted electrical signal, point spread function data is generated, and subjected to Fourier transform to calculate an optical transfer function. Accordingly, a method is provided for measuring an optical transfer function for properly restoring image degradation due to factors including the position of the imaging optical system within the imaging camera and inter-element cross talk.
