Title: Left margin setting circuit
Inventor: OUCHI YASUSHI
IPC: G06F3/12
Filed: 1985-01-18
Abstract: PURPOSE:To make it possible to set the left margin with the precision of the least dot diameter by providing a stop signal generating circuit for transiently stopping generation of load pulses loading parallel data to a shaft register for P/S conversion. CONSTITUTION:A line start synchronizing signal LSYN is detected by a horizon tal synchronizing detector 21. In timing with the immediately following driving clock VCLK, a preset signal is transmitted to a left margin setting counter CT22 for setting the initial value. The CT22 counts VCLK and, when it reaches a preset value, sets a signal A to an H level. The P/S conversion shift register SR25 loads parallel signals by a load signal from a load pulse generating circuit 24. At a preset value before generation of the signal A, the CT22 transmits signals to a weight timing generating circuit 23 to stop the operation of the circuit 24 for a moment to set a loading state for SR25 (shift register). A CT22 releases the stop signal for the circuit 23 before one VCLK of the signal to output serial data from the SR25 to output a printout data WVDO via AND circuit.

Title: Device for liquid-phase epitaxial growth
Inventor: KASAMA YASUHIKO
IPC: H01L21/208
Filed: 1982-01-25
Abstract: PURPOSE:To prevent the extraordinary growth of crystals in the peripheral part of a substrate by a method wherein the central part of the substrate having an appropriate area, other than the peripheral part, is covered with an insulating film whose melting point is sufficiently higher than the temperature of growing, and a substrate formed of a material having the same quality with that of said substrate is arranged on a melt. CONSTITUTION:A slider 2, which forms the bottom of a melt cistern 1a, is inserted slidably into the main body 1 of a carbon boat, and a substrate 3 whereon growth is to be made is fitted and supported by a recess 2a for holding 2a of the slider. The substrate 3 has an area somewhat larger than that of the melt cistern 1a and is held between the main body 1 of the boat  and the slider 2 so that it does not rise up from the bottom of a melt 4. The central part of  the main body 5a of a substrate 5 formed of GaAs is covered with an insulating film 5b  formed of SiO2 or the like. When liquid-phase epitaxial growth is made in such a device, the  growth is made, in the central part of the melt 4, only on the substrate 3, while it proceeds, in the peripheral part thereof, both on the substrate 3 and in the exposed part of the main body  5a of the substrate 5. Therefore, the speed of growth of crystals in the peripheral part becomes smaller than that in the central part. This difference becomes remarkable when the ratio of the thickness of the melt 4 to that of a growing layer is small, and thus the extraordinary growth of crystals in the peripheral part can be reduced.
