Circuits for adjusting the duty cycle of a clock(s) signal include a negative feedback loop for applying an offset signal to the uncorrected clock signal(s). The offset signal, which corresponds to a duty cycle error of the corrected clock signal(s), adjusts the slicing level of the uncorrected clock signal(s) to cause the duty cycle error to converge toward a predetermined value, for example, zero. The techniques may be used to adjust the duty cycle error of differential clock signals as well a...

A duty cycle regulator derives from an input clock of arbitrary duty cycle, an output clock having an adjustable duty cycle of similar frequency. The duty cycle regulator includes a bistable circuit for receiving an input clock pulse and providing the output clock, coupled through a feedback loop to an adjustable delay unit having a delay interval equal to an adjustable fraction of the input clock period. When an input clock pulse is received, the bistable circuit is set, providing a high signal...

When a tread thickness from a second belt ply 7B is defined as T, Tmin is provided in a region Y which is away from a tire equator C by a distance of 0.5 to 0.7 times of a tread grounding half width WT/2. A ratio Tmin/Tc between said minimum value Tmin and the tread thickness Tc at the position of the tire equator C is 0.92 to 0.97, and a ratio Tb/Tc between a tread thickness Tb at a position of an outer end of the second belt ply and Tc is 0.95 to 1.10. When a tread thickness from a carcass 6 i...

A heavy-duty tire, wherein each bead portion (2) is defined by a metal bead bundle (3), about which are turned up a body ply (8), a reinforcing strip (9), and an outer cover layer (10). The outer cover layer is defined by an innerliner (11), an abrasion gum strip (12) which is connected to the innerliner (11) by a splice (14) and is located beneath the innerliner (11), and a sidewall (13). Between the reinforcing strip and the outer cover strip (10), there is inserted a damping strip (21) direct...

A dual tube shock absorber has a base valve assembly which includes both low speed control using a bleed type orifice and high speed/high pressure blow off control using a disc spring. The base valve assembly provides this variable damping force characteristic while reducing the dead length of the shock absorber.

A tow hitch having a shell and a draw bar in which the draw bar fits into a channel formed on the shell such that the draw bar may be shifted along the entire length of the channel and either enter or exit on either end of the channel. The shell is adjusted for connection to a tow vehicle.

A device that uses an input clock signal to generate an output clock signal with a desired frequency is provided. The device uses a voltage controlled delay element that outputs a reset signal to a flip-flop dependent on a bias signal and the input clock signal. When triggered, the flip-flop outputs a transition on the output clock signal, which, in turn, serves as an input to a duty cycle corrector that generates the bias signal dependent on the configuration of the duty cycle corrector. The du...

A heavy duty radial tire which is provided with traverse grooves extending between the tread edges and longitudinal grooves extending between the traverse grooves so as to form shoulder blocks arranged along each of the tread edges and inner blocks each disposed on the axially inside of one of the shoulder blocks. The longitudinal grooves between the shoulder blocks and the inner blocks have a depth Dga of 0.7 to 1.0 times the depth Dy of the traverse grooves, and the longitudinal grooves are ea...

A heavy duty tire comprises a carcass ply turned up around a bead core in each bead portion to form a pair of turnup portions and a main portion, and a bead reinforcing layer disposed in the bead portion and comprising an axially outer part and an axially inner part, wherein under a 50 kPa state of the tire in which the tire is mounted on a standard rim and inflated to 50 kpa: the turnup portion inclines towards the carcass ply main portion at an angle of less than 90 degrees; the distance La of...

Method and apparatus are described for duty cycle determination and adjustment. More particularly, an output signal is sampled and provided to duty cycle check circuitry which characterizes the duty cycle of the sampled output signal. This characterization may be provided to a wafer prober or integrated circuit tester to determine whether duty cycle is within an acceptance range. Alternatively, the duty cycle indicator signal may be provided to drive adjustment circuitry. In response to duty cyc...
