A mobile communication terminal for transmitting/receiving image data over a group communication network includes: a push-to-talk (PTT) key for requesting a transmission right in a group communication mode; a vocoder for encoding a user voice signal received via a microphone; a memory for storing various image data; a controller for combining voice data received from the vocoder with the image data read from the memory to form a packet, or separating the image data from the received packet to perform an output control process; and a transceiver for transmitting packet data received from the controller to a group communication management center, or receiving the packet data from the group communication management center.
摘要:
Provided are methods for manufacturing improved cerium oxide abrasives suitable for forming slurry compositions suitable for CMP processes. The cerium oxide abrasives are produced by the heat treatment of a mixture of a cerium precursor compound and an impurity metal compound under conditions that produce primary cerium oxide particles that are incorporated in larger secondary abrasive particles. The presence of the impurity metal and/or the incompletely oxidized cerium within the secondary abrasive particle tend to reduce its mechanical strength, thereby reducing the likelihood of damaging a substrate surface during a CMP process utilizing such abrasives.

Disclosed is a device for measuring the concentration of the particles contained in a fluid. The device comprises a control volume body having a predetermined effective volume. An inlet path is formed at an end of the control volume body to feed the fluid into the control volume body therethrough. An outlet path is formed at another end of the control volume body to discharge the fluid from the control volume body therethrough. Measuring instruments are provided at the inlet path and the outlet path to emit electrical signals when the fine particles pass through the inlet path and the outlet path. A computing machine receives the electrical signals transmitted from the measuring instruments, and then computes the number and the concentration of fine particles contained in the control volume body. The device is easily integrated with Micro-TAS (Total analysis System).
