Title: Adpcm encoding and decoding system
Inventor: SHINADA SHIGEO
IPC: H04B14/06
Filed: 1987-06-01
Abstract: PURPOSE:To reduce encoding distortion by executing the control to a polarity predicting side for MODEM or to another pair of polarity predicting side for sound according whether the value of the predicting coefficient of an adaptive polarity prediction is in a change range to a prescribed MODEM signal or not. CONSTITUTION:A MODEM signal discriminating device 11 decides whether the predicting coefficient of an adaptive polarity prediction outputted by an adaptive polarity predicting device 9 comes into a prescribed area or not and decides it is a MODEM signal when it is in the area and besides the MODEM signal when it is out of the area. Based on the result, a linear coupling constant is alphaj is generated by a linear coupling constant generator 12, the output of the adaptive polarity predicting device 9 is multiplied by this coupling constant alphaj, the output of a fixed polarity predicting device 10 is multiplied by a 1-alphaj with a multiplier 16, by adding the outputs of multiplier 15 and 16 with an adder 20; a polarity predicting value SPj is obtained and a predicting signal SEj is obtained by an adder 19 from a zero- predicting value SEZj and the polarity predicting value SPj. Thus, since whether an input signal is the MODEM signal or not can be securely decided, encoding distortion can be erased to the MODEM signal.

A thermosetting group-containing primary amine of formula II (R3 is reactive organic group) (e.g. 4-aminophenyl-1-propargyl ether) is then added to the reactional system and allowed to react therewith. Thereby, a both end terminated telechelic oligoamic acid is obtained, finally cyclized and imidated to afford the objective oligomer of formula III (n is 0-20). In order to cyclize the oligoamic acid, toluene is preferably added to the reactional system and the cyclization is preferably carried out by refluxing the reactional mixture while distilling away water as an azeotropic mixture.

Title: Recognizing/preventing circuit for hit of control line
Inventor: OKURANO TSUTOMU
IPC: G06F3/00
Filed: 1989-05-31
Abstract: PURPOSE:To prevent a control line from being misrecognized at its disconnection without increasing the load of a processor by finding out the logic of plural delay signals outputted from a delay means and comparing a previously set time with the continued time of a hit. CONSTITUTION:When a '0' level signal having a continuous time more than a disconnection recognizing time to be a reference is generated on the control line 21, four delay signals 24 having respectively different delay times are outputted and simultaneously inputted to an OR gate 16. In the period when all the four delay signals 24 are turned to the '0' level, an output signal 25 generated from the OR gate 16 is turned to the '0' level and sent to a data bus 22. Thereby, if the '0' level signal appearing on the control line by disturbance e.g. is less than the previously set time width, the state is not recognized as the disconnection of the control line 21, but when the signal is more than the set time width, the disconnection of the control line 21 is recognized. Consequently, the load of the microprocessor can be reduced and the misrecognition of disconnection can be suppressed.
