Granted: 2001-12-01
Abstract: A sand hopper (28) with a mold sand (S1) is provided at its lower position (40) with a plurality of nozzles (42) and a plurality of squeeze feet (46), the pressure of which is controlled, and which are located adjacent to a side of each squeeze foot. The sand hopper (28) is supported by supporting means (22, 26) such that it can move vertically. A mold space is defined by a pattern plate (72a) with a pattern (74a), a flask (4), a filling frame (52), and a sand hopper (28) with a plurality of squeeze feet (46) disposed above the filling frame (52). By discharging molding sand from the nozzles (42), it is introduced into the mold space. The mold sand (S2) in the mold space is compacted by the squeeze feet by lowering the sand hopper toward the mold space. Since the molding machine is so arranged, both introducing molding sand into a mold space and compacting the introduced molding sand are performed at a working space (filling-compressing space), then fill mold sand into molding space and compress filled molding sand.

Title: Constant current driving circuit having automatically clamp precharging function
Inventor: JUANG DA-CHANG
IPC: G05F1/00
Filed: 2000-11-10
Granted: 2002-07-01
Abstract: The present invention relates to a kind of constant current driving circuit having automatically clamp precharging function, in which its constant current driving circuit is composed of switch transistors, current output transistors and precharging transistors. The switch transistor is controlled to conduct or turn off by an input terminal. The current output transistor is connected with the switch transistor and the bias output terminal of the reference bias generator such that a constant current is outputted when the switch transistor conducts. The gate of the precharging transistor is connected with the gate of the current output transistor such that they are connected together with the bias output terminal of the reference bias generator, in which the source and drain of the precharging transistor are connected with the drain and source of the current output transistor, respectively. Thus, when the output transistor outputs a constant current to drive the organic light emitting diode, the precharging transistor is conducted because the gate/source voltage is larger than the critical voltage. In addition, the precharging transistor is made to use its drain/source current to provide an extra large current to quickly charge the driven organic light emitting diode till the gate/source voltage is smaller than the critical voltage. Then, the precharging transistor automatically turns off to stop the charging.

Title: Burst based access and assignment method for providing real-time services
Inventor: BALACHANDRAN KRISHNA
IPC: H04W72/04
Filed: 2000-12-08
Granted: 2002-07-01
Abstract: A method and system for reducing delay in wireless communications by use of a burst based access and assignment system. The method for setting up a communication channel uses short burst(s) (essentially a slot of a time frame). Time is saved by keeping the uplink and downlink channels flexible and independent of each other. Thus less time is used trying to fit all requests and responses into constrained choices as in previous protocols. The result is less delay to the mobile user and greater usage density for the wireless service provider.

Title: Power management for optical drives
Inventor: KEELER STANTON M
IPC: G11B20/10
Filed: 2001-04-18
Granted: 2002-11-11
Abstract: During a ""Burst Read Mode"", an optical storage device reads data from a medium into a buffer faster than a host device reads data out form the buffer. To improve power efficiency, the optical storage device powers down read/write components when a buffer fills to a first level. The read/write components include the optical pickup unit, the spindle motor, the actuator motor, their associated electronics, and the system microprocessor. While the read/write components are powered down, the host device continues to read data out of the buffer. When the output buffer empties to a second level, a buffer logic wakes up the system micoprocessor and the system mciroprocessor powers up the read components. During a ""Burst Write Mode"", the host device reads data into the buffer slower than the optical storage device reads data out from the buffer to write the data to medium 3. To improves power efficiency, the optical storage device powers down read/write components when the buffer empties to a third level. While the read/write components are powered down, the host device continues to read data into the buffer. When the buffer fills to a fourth level, the buffer logic wakes up the system microprocessor and the system microprocessor powers up the write components. The optical storage device also transitions from one power state to another when a host device has not accessed the storage device within a specified time. In each transition, optical storage device powers down more and more read/write components until all the read/write components are powered down. Furthermore in the last power state, the buffer, which also stores the file system information from the medium, is also powered down.
