Title: Cmos latching circuit
Inventor: OURA TOSHIO
IPC: H03K3/356
Filed: 1985-10-22
Abstract: PURPOSE:To reduce an area of a chip by providing a CMOS latching circuit having an inverter whose input end and output end have been connected to a drain of a MOS FET, and a data output terminal, respectively. CONSTITUTION:The first gate input wiring is inputted to only a gate of an N channel MOS FET Q2. Therefore, the first gate input wiring is not required in a P channel MOS FET area on a chip. Also, the second gate input is connected to a P channel MOS FET Q3, and an N channel MOS FET Q6 or Q5, therefore, on the chip, it may suffice that one piece of the second gate input wiring is provided in the P channel MOS FET area, and also it is extended suitably in the inside of the chip, to the N channel MOS area. Accordingly, an occupied area for the wiring is curtailed remarkably.

Title: Manufacture of semiconductor device
Inventor: KAJIKAWA YASUTOMO
IPC: H01L29/812
Filed: 1985-10-23
Abstract: PURPOSE:To obtain a GaAs FET characterized by excellent high frequency characteristics and noise characteristics, by implanting doner atom ions in an AlGaAs layer and a GaAs layer on a GaAs substrate, thereby forming a steep free electron concentration profile in an active layer. CONSTITUTION:On a semi-insulating GaAs substrate 1, a non-added AlxGa1-xAs layer 2 and a non-added GaAs layer 3 are grown. Doner atom ions are implanted and annealing is performed so that the doner atoms are activated in the GaAs layer 3. Most of the doner atoms in the AlxGa1-xAs (0.3<=x<=0.6) crystal form a deep level called a DX center. The ionizing energy at this level is 100meV or more. Ionization hardly occurs at a room temperature. Therefore free electrons are not generated. When ions are implanted in a wafer having such a structure and annealing is performed so that a doner atom concentration profile (b) as shown by a broken line is formed, free electrons are generated only in the GaAs epitaxial layer 1. A free electron concentration profile (a), which has steep rise-up at the interface between the GaAs layer 3 and the AlGaAs layer 2, is obtained. By implanting the doner atom ions in the AlGaAs layer and the GaAs layer on the GaAs substrate, the steep free electron concentration profile is formed in the active layer, and the GaAs FET having excellent high frequency characteristics and noise characteristics is obtained.

Abstract: PURPOSE:To use an education supporting system even when a master is absent by sending master picture information to a system bus, and receiving the master picture information on the system bus without interposing the master by designating a picture switching mode at a booth side. CONSTITUTION:When the picture switching mode is set by operating a picture change-over switch 64 at a booth 32, a control part 61 in a control panel 41 fetches data on an information bus 33a via an interface 62, and projects it on a monitor 40 as monitor information. When the switch 64 is operated again, the data on the bus 33a is separated from the booth 32, and its own picture information is projected on the monitor 40 at the booth 32. Meanwhile, the information on the bus 33a can be received at the booth 32 side by operating a picture reading switch 54 without interposing the master 31, and a master picture can be selected arbitrarily by the panel operation of the booth. In such a way, the system can be effectively used even when the amster is absent.
