Apparatus is disclosed for buffering writes from a CPU to main memory, in which sequential write requests to the same address are gathered and combined into a single write request. The embodiment described does not permit gathering with the write request in the buffer which is next scheduled for action by the main memory bus controller, nor does it permit gathering with other than the immediately preceding write request. The invention is implemented using a plurality of buffer ranks, each compri...

An improved direct-coupled amplifier includes a push-pull pair of transistors in an output stage that provides high output current on low quiescent current. Each such output transistor is driven by a push-pull pair of driver transistors that receives the applied signal at proper bias levels provided by forward-biased diodes (or diodes and gain element) to provide high input impedance to low output impedance signal buffering with wide bandwidth at high power levels.

A hydraulic buffer of the type in which a damping force can be controlled has a piston rod projecting from a cylinder, and a bracket attached to the projecting end of the piston rod. The bracket has at least two claws which are bent inwardly to face each other. A retainer is provided with at least two fitting portions having flukes and the fitting portions are adapted to engage with respective claws of the bracket. An actuator is attached to the retainer to control the damping force of the buffe...

A hydraulic vibration buffer for connection between two members with a case coupled with the first member, a piston rod with its top end coupled with a second member, a piston coupled with a base end of the piston rod and housed within the cylinder case so as to divide the cylinder case into first and second chambers, fluid source, a tank, and a control valve disposed in fluid paths connecting the cylinder case, the fluid source, and the tank with one another. The vibration buffer also includes ...

A conventional Beretta-type pistol is shown, having a recoil spring (26) compressed between the front of the slide (14) and a seat (28) at the rear of the guideway (13) in which the slide is displaceable. A buffer (32) is dimensioned to span across adjacent convolutions of the recoil spring (26) for slidable adjustment along the spring and has an outline complementary to the interior (18) of the slide (14) so that it may self-adjust. The buffer (32) cushions the impact of the slide abutment (22)...

A buffer cartridge for absorbing energy having a hydraulic component coupled with an energy-absorbing material component, the hydraulic component having a cylinder-piston arrangement, the cylinder being surrounded by a stack of pads made from resilient energy-absorbing material, each pad being separated by a spacer. The free end of the piston emerging from the cylinder is connected to an intercoupling member which can simultaneously apply a force to both the piston and the stack of pads. A stret...

A buffer circuit includes an operational amplifier circuit, a first emitter follower circuit whose base is driven by an output of the operational amplifier circuit and whose output is fed back to an inverting input terminal of the operational amplifier circuit, and a second emitter follower circuit whose base is also driven by the output of the operational amplifier circuit and whose output drives a load circuit. In another form, the buffer circuit also includes a current control circuit that de...

A finishing line including at least one buffer operable to receive printed products and deliver the printed products to the same or different finishing line. The buffer allows the finishing process to continue operating while one section of the finishing line is being repaired.

The present invention provides a buffer circuit meeting both of low power consumption requirement and an improvement in slew rate characteristics which are in a relation of trade off. Voltage difference detection circuits are provided for detecting a voltage difference between the input signal at rising and at trailing and an output signal. Based on the voltage difference, voltage-current conversion circuits increase a bias current to be supplied to an output NMOS transistor m1 and a source term...

An output of a first ring counter is held in a first storage circuit. Outputs of a second ring counter and the first storage circuit are input to a first AND circuit group. An output of a third ring counter and an output of the first storage circuit are input to a second AND circuit group. Outputs of the first AND circuit group are input to a first OR circuit. Outputs of the second AND circuit group are input to a second OR circuit. An output of the first OR circuit is stored in a second storage...
