Title: Method and apparatus for coding and decoding dpcm
Inventor: AIKOU SHINICHI
IPC: H03M3/04
Filed: 1983-07-29
Abstract: PURPOSE:To eliminate the effect of the initial state of an adaptive forecast filter by utilizing a silent period of a voice signal so as to obtain a state equal to the state where a feedback loop of a coder is cut off temporarily. CONSTITUTION:During the silent period where no voice signal exists, ej and Xj are sufficiently small values, resulting that a value of CiXDi is a sufficiently small value and the value is zero when the length of operating word is limited to a suitable length. If the value CiXDi is zero as to all taps, the forecast value Xj being an output of an adaptive filter is zero during the silent period so as to eliminate the effect of the initial state at application of power. The value of the CiXDi is sometimes not zero actually during the silent period, the CiXDi is supervised always by using a limit circuit 260 and the forecast value Xj is zeoed by bringing the CiXDi forcibly to zero if the CiXDi is <=1111.

Filed: 1988-06-07
Abstract: PURPOSE:To improve the extent of riding quality at the time of deceleration by making the deceleration larger (rounding a deceleration command signal) attending on lapse from deceleration starting time of the deceleration command signal, and when shifting to a first speed command signal after enlarging the deceleration, it shifts as being gradually reduced. CONSTITUTION:After an elevator cage is reached to the maximum speed, when it arrives at a spot short of the specified distance of a stop scheduled floor, a first speed command signal VP1 starting deceleration is generated, setting a lower speed than the said maximum speed to the highest value, and if a different value VRB in difference with this signal VP1 becomes less than the specified value VRC, a second speed command signal VP2, decelerating it as long as the specified time with the elapse of time afterward, is generated. The different value VRB is decreased along with decrease of the signal VP1 from the signal VP1 after being decelerated as long as the said specified time and the signal VP2, while a third speed command signal, subtracting the different value VRB from the signal VP1, is generated. Consequently, the speed command signal at the time of deceleration starting is rounded and, what is more, the speed command signal is decreased after this rounding is over.

Abstract: PROBLEM TO BE SOLVED: To conduct the work of adjusting the position of a detection area without the need of a special work environment in a short time by providing a select processing means for removing unnecessary detection data from the detection data on a detected material, selecting only the detection data corresponding to a preset reference target, and outputting the same. SOLUTION: A laser diode(LD) 2 is controlled by a LD driving circuit 3 in every light emitting timing made by a control circuit 7 to output a laser beam. The laser beam is scanned by a scanning device 1 and irradiated to an area wider than the detection area. When the laser beam is reflected by a detection object to be returned, the laser beam is detected by a photodiode(PD) 5, and input to the control circuit 7 through a photodetecting circuit 6. In the control circuit 7, the distance, direction and photodetecting amount data are first generated from a photodetecting amount signal and a scanning direction signal input from a scanning position detecting device 4. The data are generated every time light is emitted and detected in a detection area narrower than the scan area, whereby the detection process is conducted only for a material to be detected in the detection area.
