Title: Manufacture of thin film transistor
Inventor: MATSUMARU HARUO
IPC: H01L29/40
Filed: 1984-07-25
Abstract: PURPOSE:To enable the gap between source and drain electrodes to be formed with good accuracy by utilizing the thickness of a deposited film produced by evaporation or the like as the gap between source and drain electrodes, and by removing the intermediate layer by the technique of air isolation. CONSTITUTION:A metal difference from Cr, such as Cu, is deposited on the source electrode (or drain electrode) 2. This metal is formed on the source electrode (drain electrode) as shown by a numeral 3 by the photoetching technique. Next, Cr is deposited and formed into a drain electrode (or source electrode) 4 by the photoectching technique. An N<+> a-Si:H film 5, a-si:H film 6, and Si nitride film 7 are successively deposited thereon, and these films 5, 6 and 7 are selectively etched with plasma; further, the air isolation metal 3 is removed with an etchant. In this case, an etching solution which does not etch the source- drain electrode metal is used. Finally, a metal and a clear conductive film are deposited on the Si nitride film, and a gate electrode 8 is formed.

Title: Controller for video conference among many sites
Inventor: WAKAHARA TOSHIHIKO
IPC: H04N7/15
Filed: 1988-06-23
Abstract: PURPOSE:To synthesize pictures of many sites with one picture to apply a controller to even video conference among many sites whose number exceeds six by segmenting only required parts of picture of designated sites or segmenting out designated parts after reduction and synthesizing them. CONSTITUTION:Control signals for picture designation from respective video conference terminals 1a-1h to a controller 13 of video conference among many sites are used to report the site of synthesis, reduction or non-reduction, segmenting coordinate positions, and synthesis coordinate positions from the video conference terminal side. For the purpose of coping with the request of picture designation from each video conference terminal, a video multiple switching part 11 segments the video signal from the video conference terminal from the designated position or cuts out the reduction signal. These cut-out signals are synthesized based on control signals from respective video conference terminals, and further, superimposed video signals are outputted to video processing parts 4a-4h. These video signals are encoded again in video processing parts and are multiplexed with audio signal from audio processing parts 7a-7h and are subjected to code conversion in interface parts 3a-3h and are distributed to respective video conference terminals 1a-1h through line groups 10a-10h.

Title: Fabrication of semiconductor laser
Inventor: UDA AKIHIRO
IPC: H01S5/00
Filed: 1995-06-20
Abstract: PURPOSE: To obtain a semiconductor laser excellent in uniformity and controllability in which no damage is left on the crystal by inserting a cap layer of InGaAs or InGaAsP between an InP clad layer and a dielectric layer. CONSTITUTION: An n-type InP clad layer 2, an InGaAs P active layer 3, a p-type InP clad layer 4, etc., are formed on an n-type InP substrate 1 by MOVP and an InGaAs cap layer 4 is formed on the p-type InP clad layer 4. Since a cap layer of InGaAs or InGaAsP is inserted between the InP clad layer and a dielectric layer, the cap layer is etched earlier than the InP clad layer when a vertical mesa is subjected to wet etching following dry etching, and thereby a reversed mesa shaped InP layer is not formed. Consequently, the width of the active layer can be controlled accurately, the layer damaged through dry etching can be removed and a good buried layer can be obtained.

Title: Luminance signal recording system in video tape recorder
Inventor: KAWASAKI MOTOAKI
IPC: H04N5/922
Filed: 1981-09-30
Abstract: PURPOSE:To reduce the generation of crosstalk of a luminance signal produced from both side tracks at reproduction, by recording signals on a magnetic tape while inverting the phase of luminance signal at each two-field, in a VTR of azimuth recording system. CONSTITUTION:Luminance signals are separated from a video signal of a TV camera at an LPF 1 and applied to an FM modulation circuit 2. An output of the circuit 2 is amplified 4 via an HPF 3 and the phase is inverted at a phase inverting circuit 5. Further, a frequency-division circuit 7 1/2-frequency- divides the phase detection signal of a rotary drum and gives the result to an electronic switch 6, from which an FM luminance signal with inverted phase is sequentially outputted at each 2-field. A chrominance signal is separated from a BPF 8 and frequency-converted at a low frquency conversion circuit 9 and given to a video amplifier circuit 11 via an LPF 10. The FM luminance signal of the switch 6 and a low frequency converted luminance signal of the circuit 11 are mixed at a mixing circuit 12 and recorded on a magnetic tape. Thus, the generation of crosstalk of luminance signal at reproduction can be prevented.

Abstract: PURPOSE:To make the load of a communication controller uniform and to evade an overload state by inhibiting or permitting the execution of a next transmission/reception start command from a central processor according to an increase or decrease in the load of the communication controller. CONSTITUTION:The processor 5 controls the transmission and reception of a communication circuit and inputs a maximum load state detection signal 106 or proper load state detection signal 107 from a monitoring circuit 9 at every unit time. A counting circuit 7 counts a scanning pulse signal 101 from the processor 5, and outputs ''1'' as a carry signal 102 when entering an overflow state to stop the counting operation.

When the signal 105 varies from ''0'' to ''1'', the circuit 9 sets the signal 106 to ''1'' or when the signal varies from ''1'' to ''0'', the signal 107 is set to ''1''. The processor 5 generates the 1st interruption for inhibiting the transmission/reception start command to the CPU1 when the signal 105 is ''1'' and the 2nd interruption for permitting the transmission/reception start command when the signal 106 is ''0'' and the signal 107 is ''1''.
