摘要： A riding lawn mower comprises a frame supported by wheels, a mower housing carried at the underside of the frame, a plurality of cutter blades located within the mower housing to cut grass, a collection bag mounted on the rear of the frame, a discharge chute extending between the mower housing and the collection bag and defining a clipping path from the cutter blades into the collection bag, a blower including an impeller housing attached to the mower housing and an impeller located within the impeller housing and cooperating with the butter blades to convey the grass clippings into the collection bag through the discharge chute. A short conduit connects the impeller housing to the upstream end of the discharge chute to conduct an air generated by the impeller into the discharge chute. A central axis of the conduit is offset downwardly from a central axis of the discharge chute.

摘要： A spindle 51 capable of controlling quantitatively the rotational angle around the center axial line itself is mounted with a turning tool 50; the spindle 51 and a workpiece are allowed to be relatively dislocated by an axial control along at least a plane perpendicular to the rotation axial line of the spindle 51 in such a manner that the relative movement locus L of the spindle center Cs to the workpiece conforms to a geometry to be machined and a required front rake angle .beta. is set, thereby allowing a mutual interpolation motion between the spindle and the workpiece to be performed; and the rotational angle of the spindle 51 is synchronously controlled with a required interrelation to the above-mentioned axial control, whereby the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece is kept at a required direction at the full rotational angle position of the spindle 50 with the required front rake angle .beta., and the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece W is kept at a required direction, and then the workpiece W is machined into a geometry determined by the interpolation locus L due to the above-mentioned mutual interpolation motion.

摘要： A motorcycle having an internal combustion engine mounted on a main frame and including suction and exhaust systems, an exhaust gas cleaning means adapted to supply secondary air to the exhaust system for cleaning an exhaust gas flowing therethrough, a carburetor provided in the suction system and provided with a throttle valve therein, and a throttle opener provided on the carburetor and adapted to open the throttle valve slightly while the internal combustion engine is decelerated. A secondary air supply passage is connected to the exhaust system, and a flow rate of the secondary air flowing through the passage is controlled by a secondary air control valve. When a vehicle speed of the motorcycle has decreased to a level not higher than a predetermined level, the secondary air control valve is closed to stop supplying the secondary air to the exhaust system, and the operation of the throttle opener is rendered ineffective simultaneously. This prevents the temperature of the exhaust gas from increasing. Accordingly, a change in the color, and the discoloring, of an outer surface of the exhaust system can be prevented. Also, a decrease in the effect of engine brake can be prevented effectively.

摘要： Herein disclosed is an exhaust gas recirculation system for an internal combustion engine, in which system communication is provided between an exhaust passage and an intake passage by way of an exhaust gas recirculation passage so that the exhaust gas in the exhaust passage is partially recirculated into the intake passage by the intake vacuum prevailing in the intake passage. The exhaust gas recirculation system is constructed to include: a vacuum-operated type exhaust gas recirculation valve disposed midway of the exhaust gas recirculation passage for regulating and controlling the flow rate of the exhaust gas to flow in said exhaust gas recirculation passage; a vacuum supply passage for providing communication of a vacuum chamber of the exhaust gas recirculation valve with the intake passage downstream of a throttle valve; a vacuum control valve connected with the vacuum supply passage for controlling the vacuum force of intake air to flow in the vacuum supply passage; and an interlocking mechanism for interlocking the vacuum control valve and the throttle valve. As a result, the exhaust gas recirculation control can be properly conducted, and a rider is enabled to do his throttling operation smoothly and lightly.
