    • An automotive engine control system is provided for an automobile having a variable rotation speed engine which has a plurality of spark plugs served by respective spark plugs. The system includes an optical rotary encoder having a rotatable pulse scale having a row of code pattern with specific light-permeable or light-deflection slits each for outputting a reference position signal and other light-permeable or light-reflection slits each adapted to reduce the amount of light for outputting an angular signal, both of the optical signals being photoelectronically converted and the waveform of the resultant electric signals being shaped based on threshold voltages into electric pulse signals indicative of a reference angle of 0.degree. and the accumulated angle of rotation, in which the circumferential width of each specific reference slit is made narrower than that of other slit so that the pulse width for angular position-indicating of the angular pulse signal is always equal and constant for ensuring more accurate detection of the angle of rotation. As the engine rotation speed is sensed to speed up and slow down, by a sensor that is operatively connected with the engine, the optical rotary encoder varies igniting of the spark plugs.

    • An apparatus for non-invasively measuring the concentratiuon of a predetermined substance in blood. Light of first and second wavelengths is emitted through a pulsating living tissue, either alternately of simultaneously. The amounts of light of the first and second wavelengths transmitted through the pulsating living tissue are measured for first and second different thicknesses of the pulsating tissue. A calculation is then carried out to determine the concentration of the predetermined substance based on the detected amounts of light of the first and second wavelengths when the pulsating living tissue has the first thickness, the amounts of light of the first and second wavelengths detected when the pulsating living tissue has the second thickness, and absorption coefficients of the substance and absorption coefficients of water at the first and second wavelengths.

    • An asynchronous transmission system for binary-coded information is disclosed. According to this system, in a transmitting terminal (A), when successive data of the same code in a set of asynchronous data lasts for a predetermined period of time (T.sub.1), a refresh pulse, the polarity of which is opposite to that of the successive data, is added to a transmission signal. However, the addition of such a refresh pulse to the transmission signal is inhibited for a predetermined period of time (T.sub.2) to allow for a change of data. In a receiving terminal (B), a pulse, the width of which is larger or equal to a minimum period of data, and a pulse, the width of which is smaller than or equal to a pulse-width (T.sub.0) of a refresh pulse, can be discriminated and removed by a pulse-width discrimination circuit. As a result, the refresh pulse is not present in the output signal of the pulse-width discrimination circuit. Thus, the original asynchronous data is restored.
