IPC: F16H9/18
Filed: 1987-09-11
Abstract: PURPOSE: To prevent an increase in the fore/aft length of a motorcycle body by fitting a V-belt transmission and a transmission mechanism between an engine and a rear wheel, and disposing the driving pulley and the driven pulley of a V-belt transmission vertically. CONSTITUTION: At a power transmission system ranging from an engine 5 to a rear wheel 4, a V-belt transmission 8 and a transmission mechanism 9 are connected. In the V-belt transmission 8, a driving pulley 10 and a driven pulley 11 are disposed vertically. The transmission mechanism 9 is constituted of a drive shaft 9a, and its input end and output end are disposed fore and aft. The driving pulley 10 and the driven pulley 11 of the V-belt transmission 8 are arranged so as to be disposed vertically, therefore, a distance between the engine 5 and the rear wheel 4 can be reduced. It is thus possible to eliminate a wasteful increase in the fore and aft length of a motorcycle body.

Filed: 1986-09-26
Abstract: PURPOSE:To prevent a false signal from appearing when the applied voltage to a secondary electron multiplier is switched to the high speed and prevent a trouble by making the voltage across a dynode terminal and an anode constant regardless of the whole applied voltage to the secondary electron multiplier. CONSTITUTION:A means keeping the voltage across the portion nearest to the anode 3 of a secondary electron multiplier and the anode is provided between them. In this case, a constant-voltage source 6 is inserted between a final-stage dynode 1b and a shield 2, the constant voltage across the dynode lb and the anode 3 is not guaranteed, but the shield 2 is at the 0 potential and the voltage of the anode 3 is changed by the signal current flowing through a load resistor 7, but the voltage across the dynode 1b and the ground is kept constant by the constant-voltage source 6, thus the voltage of the dynode 1b with respect to the anode 3 is invariably constant, and the electrostatic effect does not appear on the anode even if the applied voltage to the secondary electron multiplier is changed abruptly. The applied voltage can be switched optionally even during the detection of radioactive rays, and the deterioration of the secondary electron multiplier can be prevented by decreasing the applied voltage in advance when an excessive input is expected.
