Title: Sub-carrier modulation optical transmitter and sub-carrier modulation optical receiver
Inventor: UCHIUMI KUNIAKI
IPC: H04B10/58
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To provide the SCM(sub-carrier modulation) optical transmitters of high quality and SCM optical receivers capable of coping with them by reducing clip distortion and low excitation distortion even in the case that large signal amplitude is inputted to the SCM optical transmitter. SOLUTION: One of FDM (frequency multiplex) signals outputted from an amplifier circuit 12 is inputted to an FDM signal amplitude detection circuit 101 and the other is inputted to an amplitude limiter circuit 102. The FDM signal amplitude detection circuit 101 detects the amplitude value of the FDM signal and outputs control signals corresponding to it and the amplitude limiter circuit 102 limits the amplitude of the inputted FDM signal based on the control signals. In this case, limiting is performed so as to make the amplitude of the FDM signal after a bias is imparted in the bias circuit 13 of a poststage be larger than a boundary for generating the clip distortion or the like in an LD 14. Thus, even in the case that the large signal amplitude is inputted, the clip distortion and the low excitation distortion are not generated.

Title: Method and device of clamp completion confirmation in vice unit
Inventor: MORIYA KIKUO
IPC: B23Q17/00
Filed: 1990-11-21
Abstract: PURPOSE:To confirm clamp completion correctly with good reliability by outputting a clamp completion check signal when it is decided that a clamp pressure of more than a predetermined value is maintained for more than a predetermined period continuously. CONSTITUTION:Timer values Ta, Tb are initiallized, and then it is determined if a clamp pressure P reaches a predetermined value Pset which is equivalent to a preliminarily determined clamp completion pressure or not. The predetermined value Pset is set and changed corresponding to the clamp completion pressure, and when the pressure P>=Pset, the timer value Ta is enlarged by one. It is then determined if the timer value Ta reaches a predetermined Taset or not. When the timer value Ta>=Taset is the time when the clamp pressure P more than the predetermined value Pset equivalent to the predetermined clamp completion pressure is maintained for more than a predetermined period decided by Taset, and a clamp completion confirmation signal is outputted at this time.

Title: Thinning learning control system
Inventor: TOYOSAWA YUKIO
IPC: G05B13/02
Filed: 1989-12-05
Abstract: PURPOSE:To control learning with a small number of memories without degrading the performance by thinning and storing information to be stored in the memory of a delay element and causing components thinned by thinning to pass a smoothing filter. CONSTITUTION:When the manipulated variable is corrected based on correction data to control a servo motor, the control deviation obtained at each time of sampling is thinned and stored in the memory at prescribed intervals, and data of the control deviation equivalent to one prescribed period is successively stored. When correction data is calculated after one prescribed period, the stored control deviation is used to calculate correction data at a time corresponding to the timing when the control deviation is stored at prescribed intervals, and the control deviation is estimated by the smoothing filter processing based on the stored control deviations at both end points of components removed by thinning to obtain correction data for the timing of thinning. Thus, learning is controlled though the number of memories where the control deviation is stored does not reach the number of memories required for storage of the control deviation for each sampling corresponding to one prescribed period.

Title: Information processor
Inventor: FUJII SHIN
IPC: G06F1/26
Filed: 1990-11-21
Abstract: PURPOSE:To inform the abnormality of an input device to a main processor without increasing the number of lines or changing a transmission method by reducing the power consumption of the input device at the time of generating the abnormality in the input device, monitoring current supply to the input device and detecting the abnormality of the input device in accordance with a change in the current supply. CONSTITUTION:A current drop detecting part 42 always measures the current value of power sent to the input device 50, and when the current value is dropped lower than a prescribed value, detects the current drop and sends the detected result to a main control part 41 through a signal route 46. The main control part 41 decides the abnormality of the device 50, executes prescribed abnormality processing and informs an abnormality generating signal to an external alarm device, a display, etc., through a signal route 47. At the time of receiving a stop signal and a power down instructing signal from a watchdog timer 52 through the signal routes 55, 56, an input control part 51 stops processing operation and inactivate internal operation to reduce power consumption. Thus the abnormality generation of the input control part can be immediately informed to the main processor without increasing the number of lines or changing the transmission procedure.
