Title: Formation of compound semiconductor epitaxial layer
Inventor: OHARA TAGAHIKO
IPC: H01L21/205
Filed: 1988-03-25
Abstract: PURPOSE:To selectively form a compound semiconductor epitaxial layer by a method wherein a portion of a first compound semiconductor epitaxial layer is etched to expose the surface of an Si substrate, and thereafter a second compound semiconductor epitaxial layer is formed. CONSTITUTION:A first GaAs epitaxial layer is formed on an Si substrate 1. A portion of it is removed by etching and a groove 3 is formed, and the surface of the Si substrate 1 is exposed. Then, the second GaAs epitaxial layer 2b is formed on the first GaAs epitaxial layer 2a. Since a natural oxide film is formed on the surface of the Si substrate 1 exposed in the groove 3, the desired GaAs epitaxial layer 2 is selectively formed without forming the second GaAs epitaxial layer 2b on this portion.

Abstract: PURPOSE:To relieve the load of a processor and to reduce the frequency of use of a bus by providing plural data collection units, a control unit having a processing transfer command and a data transmission unit and interconnecting them with a bus from a processor of the control unit. CONSTITUTION:State information of a subsequent equipment collected by each of data collection units 10, 11 is stored in each memory. Then a processor 3 of the control unit 1 processes the stored data and commands the transfer of the data to the data transmission unit 2.

Abstract: PURPOSE: To make it possible to judge the presence or absence of a key input with respect to the function impossible to immediately print in correspondence with the key input by driving a part of the ordinary typing actions with respect to the key input upon using the decimal tab function and centering function.  
     CONSTITUTION: Complication of a program is dissolved by rendering a part of the printing actions of ordinary function into a signal relative to presence or absence of a key input. Alternately, the presence or absence of the key input is judged by a buzzer sound or a display, and the consumable power is reduced as much as possible. Regarding the rotation of a type wheel 2, a hammer 4, an ink ribbon 3, and a platen 1 are fixed, and only a type wheel 2 is rotated so that a character corresponding to the key input comes to the hammer position. Regarding the up and down movement of the ink ribbon 3, the other parts are fixed, and only the ink ribbon 3 is moved up and down notched at every key input. Regarding the driving of the hammer 4, the notched portion 5 of the type wheel is fixed to the position of the hammer, as the ink ribbon 3 is in the descent state to fix the platen 1, thus the hammer is driven at every time of the key input.
