Abstract: PURPOSE: A power up signal generator is provided to generate a power up signal stably without regard to temperature variation, and to operate stably at a low power supply voltage by lowering a trip voltage. CONSTITUTION: According to the power up signal generator, a PMOS transistor(50) supplies a power supply voltage dropped to a node(N1) above a set voltage as a power supply voltage increases after an initial power supply voltage is supplied. A current source(54) flows a constant current by receiving the power supply voltage supplied from the PMOS transistor. The first inverter(60) inverts the voltage level supplied from the PMOS transistor to the node(N1) when the voltage level reaches a threshold voltage while a constant reference current flows from the current source. And the second inverter(62) outputs a power up signal by delaying an inverted output signal from the first inverter and then inverting it.

Title: Tensioner
IPC: F16F7/08
Filed: 2001-04-12
Abstract: The invention comprises a self-contained mechanical belt tensioner that produces damping which is a function of the applied hubload through the effect of frictional forces derived from the sliding action of mutually opposing wedges. A first wedge or conical piston is contained within a housing. The conical piston cooperates with a second or conical wedge. A surface of the conical wedge slides on the inner surface of the housing. The conical wedge is expandable in a direction normal to the inner surface of the housing. A spring urges the conical wedge into engagement with the conical piston. As the pulley is loaded, as with an impulse load, the piston will move into the conical wedge. This, in turn, will cause the conical wedge to expand against the inner surface of the housing. The expansion of the conical wedge in the housing will increase the frictional force between the conical wedge and the housing. This will have the effect of damping movements of the conical piston and, in turn, of the pulley. The greater the impulse, then the greater the expansion of the conical wedge. This increases the resultant frictional force resisting movement between the conical wedge and the housing. As the load moves toward a minimum, the frictional force is abated to a low level allowing ease of retraction of the piston.
