Title: Device and method for detecting micro-processor execution performance
Inventor: LIANG JING-JE
IPC: G06F9/455
Filed: 2001-07-11
Granted: 2004-11-01
Abstract: A method for detecting micro-processor execution performance utilizes some devices such as micro-processor, command counter and period counter and so on. First, micro-processor enters circuit emulation mode, reset the command counter and period counter as zero, and then set command cut points intended to know the command execution speed. Second, leave the circuit emulation mode and enter normal operation mode to execute commands. Command counter will add one at each time of executing one command. Period counter will add one at each clock signal passing through one period. When encounter command cut point during command execution process, leave the normal operation mode and enter circuit emulation mode. Then divide the value of command counter by the value of period counter to get the execution performance. If the count of the counter reaches the upper limit, leave the normal operation mode and enter the circuit emulation mode to get the execution performance till finish all of the commands or encountering command cut point.

Title: Apparatus for controlling introduced air in metal oxide reducing furnace
Inventor: IMAIZUMI TADASHI
IPC: F27B9/40
Filed: 2001-09-07
Granted: 2002-10-11
Abstract: An introduced-air-flow-rate SA is determined by adding an adjusted value A given from an oxygen density controlling system to a required-air-reference-flow-rate RA demanded by the charging amount of pellets. The introduced-air-flow-rate is controlled where the required-air-reference-flow-rate RA is the feed forward value. Thus, if the charging amount of the pellet is varied, since the introduced-air-flow-rate SA is determined by the adjusted value A and the required-air-reference-flow-rate RA varied in response thereto, the control response can be quickened without decrease of the stability. Further, at the abnormality of the oxygen sensor, as the adjusted value A is controlled to be zero, the required-air-reference-flow-rate RA is decided of itself as the introduced-air-flow-rate SA.

Title: Transmission convergence layer circuit of receiver for asynchronous transmission and its operation method
Inventor: TSAI DIAN-RU
IPC: H04L12/70
Filed: 2001-09-11
Granted: 2003-08-21
Abstract: A transmission convergence layer circuit of receiver for asynchronous transmission and its operation method are disclosed in the present invention, in which the circuit is connected between the buffer and the de-data-framer. The de-data-framer sends a data stream enable signal and a byte data to the circuit. After being enabled by the data stream enable signal, the circuit uses a data processing pipe to receive and temporarily store plural bytes of data of any one data cell. In addition, a header checker is used to receive these bytes of data and to search for the header. A redundancy data cell identifier is then used to identify whether the data cell is the non-redundancy data cell. After the header is found and identified as a non-redundancy data cell, a de-scrambler is used to obtain the payload data of the data cell from the data processing pipe. After the obtained data amount is large enough for a pair of data bytes, the scrambling process is conducted such that it is capable of outputting a pair of data bytes to the buffer within the minimum waiting time. Besides, the circuit is also provided with an automatic correction function when a bit data error occurs in the header so as to make the circuit capable of continuously and smoothly conducting the reception function.

Abstract: To provide a flow rate measuring method and an ultrasonic flow meter capable of accurately measuring the flow velocity of a fluid using a frequency, the phase difference of which turns into zero. A velocity of ultrasonic wave of a fluid used as a reference is prepared in a standard condition, and the ultrasonic wave is transmitted from one side in the fluid flowing in a conduit 10, and the ultrasonic wave is received on another side, and then the velocity of ultrasonic wave A is measured. The ultrasonic wave is transmitted from the other side in the fluid flowing in the conduit, and the ultrasonic wave is received on the one side, and then the velocity of ultrasonic wave B is measured. The average of the velocity of ultrasonic wave A and the velocity of ultrasonic wave B is calculated, and an absolute velocity of ultrasonic wave in the fluid is detected. Then the difference between the velocity of ultrasonic wave A and the velocity of ultrasonic wave B is divided by two, and thereby the velocity V of the fluid is detected. The velocity V is corrected using the deviation between the velocity of ultrasonic wave in the standard condition and the absolute velocity, and thereby the accurate velocity of the fluid is detected. The flow rate of the fluid is measured using the accurate velocity and the sectional area in the conduit.
