摘要： PURPOSE:To improve a sense of incongruity when a sound is heard as a voice by compressing the addition result of an addend and an augend to a maximum encoding value by a code converting circuit and outputting it when the addition result exceeds an upper-limit value, and outputting the addition result as it is when not. CONSTITUTION:This system is equipped with a full-adder 1 for encoded binary numbers, an upper-limit detecting circuit 3 which is set below the maximum value of codes, and the code converting circuit 2 which compresses values from the upper-limit value to a maximum addition value to values from the upper limit value to the maximum code value. When the addition result of this full-adder 1 is larger than the upper-limit value, the output of the code converting circuit 2 is selected and when not, the addition result of the addend (a) and augend (b) of the full-adder 1 is selected and outputted. Namely, when the addition result exceeds the upper-limit value, the addition result is compressed to a value up to the maximum code value by the code converting circuit and outputted, but when not, the addition result of the full-adder 1 is outputted as it is. Consequently, values before and after the upper-limit value is exceeded are connected smoothly, so the sense of incongruity when the sound is heard as a voice is improved.

摘要： PURPOSE:To automatize adjustment by matching an analog output signal to an upper limit value and a lower limit value and giving a setting signal and an activating signal. CONSTITUTION:The title system has a parameter calculating means 12 and a parameter holding means 16. An action to set an output signal to a specified lower limit value at the time of a zero/span adjustment, an action to set it to a specified upper limit value and an action to inform a parameter calculating means 12 that these two actions are executed are performed. At this time, except the time of the zero/span adjustment, a linear operation is executed to the A/D converted output data with a parameter held by a parameter holding means 16, the zero/span adjusted data are obtained, the data outputted to a D/A converter are controlled so that the data and the zero/span adjusted position data can be matched and the position data are analog-outputted. Thus, an adjusting work can be always automatized.

摘要： PURPOSE:To prevent hunting from being generated, by arranging an input- change-directional flag and a feedback-change-directional flag, and by detecting the excessive state of a motor from these flags and a deviation. CONSTITUTION:A motor controller is composed of a motor 1 driven by an AC power source 6, the controlling circuit 2 of the motor, a switch 3, an input signal oscillator 4, and a potentiometer 5. An input data from the input signal oscillator 4 and a feedback data from the potentiometer 5 are compared with each other by a micro-computer 2a in the controlling circuit 2 and are discriminated, and by turning the switch 3 ON/OFF, the forward rotation, reverse rotation, and stopping of the motor 1 are controlled. In this case, an input-data- change-directional flag and a feedback-data-change-directional flag are arranged. Then, from the flags and the deviation of the data, the excessive state of the motor 1 is detected, and as long as the input data does not change, the motor 1 is stopped. As a result, the response of the motor 1 can be quickened.

摘要： PURPOSE:To separate a processing started at the beginning whether it is the one due to time-up for the confirmation of the operation of a watchdog timer or the time-up due to a cause other than the confirmation of the operation by writing the operating state of a controller on a specific address in a RAM. CONSTITUTION:The content of the specific address in the RAM 2 is judged at the time of performing an initialization processing after resetting a central arithmetic processing unit 1, and a processing is shifted to an abnormality processing when data representing under execution exists, and the data is written on the specific address in the RAM 2 when no data representing under execution exists, and the content of the specific address in the RAM 2 is judged while performing a control processing after the initialization processing of the central arithmetic processing unit 1, and when it is the data representing under execution, a set signal is outputted to the watchdog timer, and when no data representing under execution exists, no watchdog timer set signal is outputted, then, a processing to perform the display of the abnormality of the watchdog timer is executed, and also, the data represented in the confirmation of the operation of the watchdog timer is written on the specific address in the RAM 2. In such a way, it is possible to perform diagnosis on the watchdog timer.

摘要： PURPOSE:To attain extract processing of an accurate characteristic quantity by smoothing a histogram projecting difference binarized picture with a centroid coordinate of a maximum area as a center and integrating the maximum area and areas in the vicinity of the maximum area into one area. CONSTITUTION:A difference processing section 4 obtains an absolute value of a difference of luminance between an input picture and a background picture and provides an output of a changes as a difference picture. A binarizing processing section 5 obtains the difference binarized picture. A labelling processing section 6 gives a label to a change area. A maximum area detection section 7 detects an area whose area is maximum. A centroid coordinate calculation section 8 obtains the centroid coordinate of the maximum area. A projection histogram smoothing section 10 obtains a maximum value and a minimum value of X and Y axes while smoothing a projected histogram of the difference binarized picture in the X and Y axis directions. A re-labelling processing section 11 gives a same label to a label of a change area in a rectangular area decided by them. Thus, an integral processing section 12 integrates an area in the rectangular area into one.
