Title: Measurement of deposit in pipe
Inventor: SHIGETA MICHIO
IPC: G01B15/02
Filed: 1985-05-30
Abstract: PURPOSE:To detect the deposit state in pipes by comparing the reference pattern of the measuring result of the pipe without deposits. CONSTITUTION:In the absence of deposit A transmitted radiation amount is linearly decreased showing a steep gradient because wall thickness of the pipe Td through which radiation from radiation source Rs passes is rapidly increased in the scanning amount range between (R/2+t) and R/2. The transmitted radiation amount is gently increased because the wall thickness of the pipe Td through which the radiation from the radiation source Rs passes is gradually decreased in the scanning range between 0 and -R/2. The transmitted radiation amount is linearly increased showing a steep gradient in the range between -R/2 and -(R/2+t). Thus, a reference pattern becomes like a horizontal letter W. On the contrary, the pattern obtained by measuring the pipe containing deposit A does not become a horizontal W because the radiation is absorbed by the deposit A. Comparison between those two patterns allows to measure existence and condition of the deposit in pipes.

Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To decrease frequency in the transmission of monitor signals by sending the monitor signals normally only to some of a plurality of connections with one computer in such a case. SOLUTION: Connections 13, 14, and 15 are established between computers 10 and 11 and the computer 10 stores connection identifiers in the activity monitor management table corresponding to the IP address of the computer 11 (500). Then the monitor signal is sent normally to one connection selected out of the three connections which are already made with the computer 11 (501). If a fault is detected at the connection 13 (501), the monitor signal is sent even to the connections 14 and 15 which are established with the computer 11 (503). Consequently, the frequency of monitor signal transmission is reduced to 1/n.

Title: Method for controlling variable value control system
Inventor: KATO TAKAAKI
IPC: G05B11/32
Filed: 1988-05-14
Abstract: PURPOSE:To improve quick responsiveness and control accuracy in variable value control by attaching feedforward control on feedback control consisting of proportional-plus-integral control, detecting the inflection point of targeted speed in a real time, and setting the integral value of integral control at the time of detecting the inflection point at zero. CONSTITUTION:In the variable value control system 7, a droop may generate for lump input by performing only the proportional-plus-integral control, however, the droop can be prevented from being generated by attaching the feedforward control 11. However, when input is changed from the lump input to step input in such system, that is, when it is changed from variable value input to constant value input, overshoot is generated. Therefore, the feedforward control 11 is attached on the feedback control 7 and simultaneously, the inflection point of the targeted value is detected, then, the value of the integral control is set at zero at the time of detecting the inflection point. In such a way, it is possible to improve the quick responsiveness and the control accuracy.

Title: Synchronization protection circuit
Inventor: KUBOTA HIROSHI
IPC: H04J3/06
Filed: 1985-05-31
Abstract: PURPOSE:To reduce the circuit scale of a synchronization protection circuit by using a counter to fetch a specific pattern detecting flag in a frame and detecting the coincidence between a counter output and a synchronization protection stage set number so as to discriminate synchronization and out of synchronism. CONSTITUTION:While a flag (FLG) input signal is in not of synchronism (synchronization), an FLG detection circuit 1 detects the leading of an FLG signal (trailing), a detection pulse is inputted to a counter reset signal generating circuit 2 and the FLG signal is inputted to a discrimination circuit 6. The circuit 2 resets the counter 4 by using a detection pulse of the circuit 1 and the counter 4 uses a frame timing pulse FT and a clock CLK to count the pulse FT inn the timing generated by a counter clock generating circuit 3. When the pulse FT is counted by the set backward protection stage number (forward protection stage number), a coincidence detection signal is outputted to the circuits 2, 6 from a coincidence detection circuit 5. Thus, the circuit 6 outputs a synchronization (out of synchronism) signal to reduce the scale of the synchronization protecting circuit.
