Title: Throttle controller
Inventor: TAGUCHI YOSHINORI
IPC: F02D11/10
Filed: 1993-11-19
Abstract: PURPOSE:To detect a throttle opening, by disconnecting the current to an electrically-driven actuator so as to detect the throttle opening when the revolutional number of an engine in higher than a specified value in accelerator- off state and make it possible to detect an abnormal state of the returning mechanism, when the throttle opening does not return to the valve closing range even if the accelerator off state is set. CONSTITUTION:When an accelerator pedal 1 is stepped on, a controller 7 drives a motor 12 in the valve opening direction R1 on the basis of the detected signal of an accelerator sensor 6. And hence a throttle valve 4 is opened through a motor lever 9 and a throttle lever 5. At that time, a limp-form lever 14 is also moved in the valve opening direction R1 and retained in a retreat position B and hence, this engagement part 16 is not engaged with to the accelerator lever 3. As a result, the throttle valve 4 is driven to opened or close independent of the accelerator pedal 1. In this case, when the revolutional number of the engine is larger than a specified value in the accelerator-off state, the controller 7 disconnects the current to the motor 12 and the returning mechanism is discriminated to be abnormal, when the throttle valve opening does not return to the valve closing range.

Title: Picture reader
Inventor: NEZU YASUTADA
IPC: H04N1/19
Filed: 1988-11-17
Abstract: PURPOSE:To prevent a reading start point and a reading completion point that are the reference of the consecutive part of picture data from being fluctuated by using a constant slicing level dedicated for scale reading. CONSTITUTION:A scale reading slicing level SLM differs from an original reading slicing level SLG set and inputted corresponding to an original 14 in real use, and the level is stored in the internal memory of a computer 23 in a state fixed at a constant value at the stage of manufacturing (delivery, etc.) of the title reader in advance as the one suitable for the scale reading by considering the degree of the dispersion in density among plural scales and that of the dispersion in density distribution at individual scale itself. Since the scale reading slicing level SLM is always kept constant, the reading start point P1 and the reading completion point Q1 can be evaded from being fluctuated even when distortion occurs in the reading waveform of an image sensor 2 due to the dispersion in scale density.
