IPC: G11B27/34
Filed: 1978-02-23
Abstract: PURPOSE: To prevent the selection errors of desired counters and confirm resetting by applying a reset command only to the one of two counters in which output is being desplayed.  
     CONSTITUTION: When a reset command is applied to a gate circuit 22 by operation of a push-button or the like, the reset command is applied to each reset input of a counter Al through AND 23, OR 25 when the display selection command is "L" and to each reset input of a counter B2 through AND 24, OR 26 when "H" level. The count value of the counter Al is displayed in a display device 7 when the display selection command is "L" level and that of the counter B2 when "H" level and therefore the reset command resets only the counter of the side which is supplying the count value to the display device 7 at that time. Thereby, the selection errors of the desired counters may be prevented and the reset of the counters confirmed.

Title: Light-emitting element provided with active waveguide and its manufacture
Inventor: SUZUKI RYOJI
IPC: H01S5/00
Filed: 1990-01-31
Abstract: PURPOSE:To easily manufacture this element and to enhance reproducibility and stability by a method wherein a protrusion-shaped mesa stripe, formed on a semiconductor substrate, whose cross section is in a trapezoid shape is not used and a mesa stripe formed to be in a peak shape is used. CONSTITUTION:A mesa stripe 10 whose cross section is in a trapezoid shape is formed on a p-type GaAs substrate 1 by using a photolithographic technique. When an etching operation is executed, the mesa stripe can be formed to be a mesa stripe 10b in a peak shape. Then, an n-type current barrier layer is epitaxially grown on the substrate 1 by using an LPE method. When a cooling rate at this growth operation, an oversaturation degree and the growth time are set properly by taking into consideration the height of the peak-shaped mesa stripe 10b at this time, the layer is epitaxially grown. When this wafer is etched by using an etchant which does not damage the flatness on its surface, one part of the mesa stripe 10b is exposed in a certain width. Since individual layers are grown to be flat on the current barrier layer 2, the interface at the individual layers is steep and a good epitaxial layer can be obtained.
