Title: Linear actuator using a slide bearing
Inventor: TOMIOKA SUSUMU
IPC: F16C29/04
Filed: 2003-03-18
Granted: 2003-12-11
Abstract: In a linear actuator, guide surfaces are defined by slide bearing members which may be essentially made of porous carbon material so that a relatively frictionless rigid bearing surfaces are provided and a favorable and durable guide action can be achieved even when the carriage is subjected to a high and/or uneven load. Also, because the lateral guide is provided by side plates of the carriage interposing a guide plate of the guide frame, and the opening width between the side plates is relatively small as compared to that of the conventional guide frame, a relatively rigid lateral guide action can be ensured. In particular if a support plate such as a table for supporting a load is connected across free ends of the side plates, the side plates are even more rigidly held by the support plate, and an even more rigid lateral guide action can be ensured.

Title: AB class amplifier for controlling quiescent current
Inventor: LEE JAE-YOUN
IPC: H03F3/30
Filed: 2003-04-14
Granted: 2004-04-11
Abstract: An AB class buffer amplifier controls quiescent current. The AB class buffer amplifier includes a first current controller and a second current controller. The first current controller sources current to an output node in response to a first logic level of a first signal, and buffers and outputs an input voltage to the output node in response to a second logic level of the first signal. The second current controller sinks the current from the output node in response to a second logic level of a second signal, and buffers and outputs the input voltage to the output node in response to a first logic level of the second signal. The first and second signals are generated at the first logic levels if the input voltage is higher than the output voltage and at the second logic level if the input voltage is lower than the output voltage. The AB class buffer amplifier may further include comparing unit which compares the input voltage with an output voltage from the output node and generates the first and second signals in response to the compared results. The comparing unit includes first and second comparators. Accordingly, the AB class buffer amplifier can drive an external circuit using high currents by freely controlling the amount of quiescent current, and easily sourcing and sinking quiescent current flowing to an output node of the amplifier.
