Title: Estimating system of bridged tap length
Inventor: TSUDA TOSHITAKA
IPC: H04B3/493
Filed: 1982-03-31
Abstract: PURPOSE:To estimate the bridged tap length, by detecting the delay time by making use of a fact that the delay time of a reflected echo which is produced by the presence of a bridged tap is proportional to the bridged tap length. CONSTITUTION:An input signal Vin crosses the threshold value VR2 at time points t2 and t3 respectively, and therefore the output CL2 of a comparator 2 falls after once rises up as shown by the figure 5. The output CL2 rises up to ''1'' from ''0'' after a fixed value detecting circuit 5 detects that the count value of a counter 1 is set at K as shown by the figure 6. As a result, a signal CE falls down to ''0'' from ''1'' as shown by the figure 7. Thus both counters 1 and 2 stop counting and hold their count values. Therefore K-X shows the difference (delay time) between the original signal S1 and a reflected echo S2. In this case, X represents the delay time of the S2, i.e., the bridged tap length since K is fixed at a certain value.

Abstract: PURPOSE:To simplify an arithmetic processing by sampling-detecting the step response of a process based on the change of a target value substituting a detecting result to the moment approximate expression of dynamic characteristics, enumerating the parameter of the dynamic characteristics and identifying the dynamic characteristics at the time of starting the control and at the time of changing the target value. CONSTITUTION:A step shape signal is given to a controlled system process 4 in a control condition based on the setting and the changing time of a target value U of control starting, and then, the response of the controlled system process 4 is step-changed. Then, the step response of the controlled system process 4 is detected by sampling, a detecting result is substituted to a moment approximate expression, and process dynamic characteristics are identified from a simplified algebraic arithmetic operation. Thus, the dynamic characteristics of the controlled system process is identified accurately and quickly with a simplified processing without executing the complicated processing of a waveform analysis, etc., and a controlled variable can be adjusted automatically.

Title: Method for adjusting relative position of rotary blade with die in submerged granulating device
Inventor: UEDA MASANOBU
IPC: B29C48/05

Abstract: PURPOSE:To maintain a fixed space between a rotary blade and a die at all times to extend a life and therefore provide a satisfactory form of finished product by fixing an impact wave receiver on a die and detecting the contact position between the rotary blade and the die. CONSTITUTION:When a rotary blade 14 is caused to contact a die 12 by putting the former in proximity with the latter, an impact wave is generated on the die 12. The space between the rotary blade 14 and the die 12 is zero and the rotary blade 14 is caused to retrogress to an appropriate position for a raw material to be granulated manually or automatically, and then is fixed at said position. Under this condition, a granulating work is started, the rotary blade 14 is periodically caused to progress automatically during granulation. Then the position where an oscillation is detected is considered to be a reference point where the space between the rotary blade 14 and the die 12 is zero, and the rotary blade 14 is caused to retrogress by a distance decided with said zero point as the reference. Thus a change with time in the thermal deformation value of a submerged granulating device is automatically corrected and the space between the rotary blade 14 and the die 12 is always maintained at a fixed value.

Title: Data communication system
Inventor: YASUDA NOBUO
IPC: H04B3/54
Filed: 1984-03-17
Abstract: PURPOSE:To attain communication with high efficiency even with a transmission line of low quality by inserting a cancel control character after the character having a transmission error in a transmission data string and at the same time continuing the data strings at and after the character that has a transmission error thereafter. CONSTITUTION:The transmission signal delivered from a certain transmission terminal Ti (i=1-n) to a bus 20 is sent through an ascending transmission cable 21 and then returned in the opposite direction at a return point 23. The terminal Ti transmits an output data string and at the same time compares a transmission data string with a reception data string successively for every character to check whether or not the signals are returned correctly. Then the terminal Ti does not transmit the next character E if a transmission error of a character D, for example, is detected and adds a cancel control character CAN to continue the data strings following the CAN after said CAN. When a reception terminal Tj receives a data string including the CAN, the terminal Tj disuses the CAN and its preceding characters and decides the rest reception data strings as a regular reception telegram.
