Title: Formation of light emitting device using gaalas wafer
Inventor: TOYOSHIMA TOSHIYA
IPC: H01L33/40
Filed: 1987-09-09
Abstract: PURPOSE:To eliminate any excessive impurity dopant by a method wherein, after growing a GaAlAs layer on a substrate, the substrate is removed to form an active layer further forming electrode layers on the opposite side surfaces. CONSTITUTION:A GaAlAs layer 2 is grown on a GaAs substrate 1 by liquid epitaxial process. The substrate 1 is removed to expose the GaAlAs layer 2 for finishing an exposed surface 4 as a mirror surface. Next, PN junction layers 5 are grown on the exposed surface by liquid epitaxial process. Thus, electrode layers 6, 7 as light emitters are formed respectively on the end surface of GaAlAs layer 2 and the surface of PN junction layer 5. Through these procedures, the electrode layers 6, 7 can be formed on the growing end surface sides of the GaAlAs layer 2 to assure the excellent electrode characteristics using less impurity dopant.

Title: Contact input circuit
Inventor: KANDA MAKOTO
IPC: H03K17/00
Filed: 1987-09-11
Abstract: PURPOSE:To make the capacity of a power supply for contact detection requiring much power consumption small by supplying power from the contact detection power supply in time sharing (time division) for each digital input unit. CONSTITUTION:A contact input circuit consists of plural digital input units 5, 6, a power supply 2 for contact state detection, and a time controller 1. The time controller 1 outputs address information comprising a command CMND and an address ADR to address coincidence circuits 51, 61 of the digital input units 5, 6 periodically. However, the address ADR is varied sequentially with addresses A and then B. The address coincidence circuit 51 receives the address ADR in response to the CMND and outputs an enable signal ENAA to a power supply switching circuit 52 when the address is identical to its own address. The power supply switching circuit 52 applies a power supply 2 to a contact state detection circuit 53 when the signal ENAA is set. Thus, the switching state of plural external contacts connecting to the contact state detection circuit 53 is detected after a delay based on the time constant of the filter circuit.
