摘要： A continuously variable speed transmission in which a bypass line is formed between two hydraulic lines disposed between a hydraulic pump and a hydraulic motor to constitute a hydraulic closed circuit, and a opening control valve is disposed to open or close the bypass line. The opening control valve is opened when the reduction rate of the engine speed or the vehicle speed exceeds a given in order to short-cut the two lines and create a neutral condition.

摘要： A speed control apparatus for a continuously variable speed transmission comprises ratio control units for controlling a speed reduction ratio and a manual value for selecting either a running range where engine power is transmitted to the wheels or a neutral range where the engine power is not transmitted to the wheels. The speed reduction ratio is controlled by the ratio control units so as to coincide with a reference speed reduction ratio corresponding to the vehicle speed detected by a speed sensor when the neutral range is selected by manual valve.

摘要： A hydraulic continuously variable speed transmission with a direct clutch valve comprises a hydraulic pump, a hydraulic motor, a hydraulic closed circuit for hydraulically connecting the both, a direct clutch valve placed in the closed circuit, a speed reduction ratio control actuator, and a direct clutch valve controlling device for controlling operations of said direct clutch valve to block the closed circuit when the speed reduction ratio becomes substantially "1". The direct clutch valve controlling device maintains a direct connecting state when an actual engine speed is higher than a direct clutch disconnecting reference engine speed at the speed reduction ratio of approximately "1". Then, the direct clutch valve control device releases the blocking of the closed circuit by the direct valve when a drop of the actual engine speed from the direct clutch disconnecting reference engine speed exceeds a predetermined amount corresponding to the vehicle speed.

摘要： The present invention relates to a metal catalyst containing fine metal particles, characterized in that the fine metal particles have a particle diameter of 3 nm or less and also have a proportion of metallic bond state of 40% or more, which is ascribed by subjecting to waveform separation of a binding energy peak peculiar to the metal as measured by using an X-ray photoelectron spectrometer. The fine metal particles are preferably fine platinum particles. The fine metal particles are preferably supported on the surface of carrier particles by reducing ions of metal to be deposited through the action of a reducing agent in a reaction system of a liquid phase containing the carrier particles dispersed therein, thereby to deposit the metal on the surface of carrier particles in the form of fine particles. The proportion of metallic bond state of the fine metal particles is adjusted within the above range by reducing after deposition thereby to decrease the oxidation state.
