IPC: F16H59/44
Filed: 1986-08-11
Abstract: PURPOSE:To prevent a shift between the points for speed change and for lock-up, by rewriting the content of a memory means every time when new voltage data are input in order to absorb the fluctuation of the relationship between the opening of a throttle opening sensor and an output voltage characteristic. CONSTITUTION:In the memory 22 of an electronic control device 11, voltage data corresponding to 0% and 100% throttle openings are stored so as to make a computing unit 21 calculate the throttle openings are stored so as to make a computing unit 21 calculates the throttle opening corresponding to any given voltage value on the basis of voltage data with 0% and 100% openings. When a new value is detected as a value for 0% or 100% opening, a process is taken to rewrite the content of said memory 22. Accordingly, because the throttle openings for detected voltage data are calculates and the possible fluctuation is absorbed, after the voltage value for 0% or 100% opening is newly rewritten in the memory, the shift of the points of speed change and lock-up can be prevented.

Title: Private line test system
Inventor: ANZAI TAKEO
IPC: H04B3/46
Filed: 1987-07-28
Abstract: PURPOSE:To obtain characteristics of incoming/outgoing lines individually by only operating one terminal station by providing a means for applying frequency conversion to a level on a loopback connecting point of both the incoming and outgoing lines. CONSTITUTION:Switches SW1, SW2 are turned on by a control signal generated at the near end at the time of testing lines W1, W2 and the oscillated frequency and the output level of the oscillator 1 are set to a desired value. The output of the oscillator is inputted to a remote end conversion circuit 2 via the line W1, rectified and smoothed (21), the carrier frequency signal having a prescribed level and frequency is subjected to frequency modulation by a smoothed output and the result is sent to the line W2. A measuring circuit 3 receiving the frequency modulation signal applies frequency demodulation to the reception signal or leaves the reception signal as it is in response to the switching of the SW3 to supply the result to a level meter 32. As a result, the transmission characteristics of the incoming/outgoing lines is measured individually by the near end operation only.
