Filed: 1990-05-15
Abstract: PURPOSE:To detect coordinates at high speed by calculating the position of placing a coordinate indicator from a guide signal caused by electromagnetic coupling between an exciting line and the coordinate indicator and between the coordinate indicator and a sense line, and detecting the coordinates by measuring time by a scanning counter. CONSTITUTION:A comparator 9 detects a signal higher than the fixed level of the generated guide signal by electromagnetic coupling between an exciting line 2 and a coil 111 in a coordinate indicator 11 and further between the coil 111 and the sense line. With the rise of this detection signal, a control circuit 10 stores the count value of a scanning counter 5 in a count register 6 and stops the operation of the scanning counter 5 with the fall of the signal. Then, by inputting the count value of the scanning counter 5 and the count value of the count register 6, the coordinate value is calculated from both values. Thus, the coordinate value can be easily calculated at high speed in a wireless condition.

Filed: 1978-10-11
Abstract: PURPOSE: To positively avoid optical damage, by letting only a wave directing layer reach to a surface of reflection by making a band gap of the wave directing layer larger than that of an active layer.  
     CONSTITUTION: A wave directing layer 12, an active layer 13 and a p-Al 0.35 Ga 0.65  As-layer 14 are manufactured on a substrate 11 by means of a liquid-phase growth method. When letting currents flow in the forward direction through an electrode 15, electrons are injected to the thin active layer 13, gains are produced and currents hardly flow through the pn junction of the wave directing layer 12 and the layer 14 because a band gap is large. Only the waveguide 12 is let reach a surface of reflection by making the band gap of the wave directing layer 12 larger than that of the active layer. Thus, optical damage can positively be avoided.
