Patent JP-H06261053-A (JP)
Title: Data transmission system
Inventor: MORI KINYA
IPC: H04L12/40
Filed: 1993-03-05
Abstract: PURPOSE:To reduce data transmission time by improving the efficiency of data input output processing at a master station. CONSTITUTION:A master station 1 makes pre-station data check processing 64 and a succeeding station address extract processing 65 for an idle time (TIN) between a master station address transmission processing 21 and a master station data reception processing 27. Since a reception processing address table 60 is used to execute input processing altogether, an input processing 50 or an input output changeover 52 is executed next to the input processing executed at present. Thus, an idle time or data processing time is in existence without fail between the master station address transmission processing 21 and the master data reception processing 27. Since the address of a pre-stage station and a succeeding station is easily recognized by a reception processing address table, the processing sets 64, 65 are processed at a high speed.

Filed: 1979-04-12
Abstract: PURPOSE:To prevent the variation of the average DC potential of the video signal, by keeping constant the peak level of the synchronizing signal section of composite video signal at the DC reproduction stage, in the synchronizing separation circuit of television receiver. CONSTITUTION:The video detection output is fed to the terminal 17 and fed to the differential pair transistors 21, 22 via the amplifying transistor 18, DC reproduction and coupling capacitor 19, and transistor 20, and DC voltage is reproduced with the comparison with the fixed potential of the base of the transistor 22. When the signal like (a) is fed to the terminal 17 as the video detection signal, the synchronizing signal level is more than the fixed potential of differential pair transistor with the amplification operation of the transistor 20, the incremental potential is compulsively lowered at the transistor 25, and the DC reproduction output appeared at the emitter of the transistor 29 is kept constant for the synchronizing signal level as shown in (b). The capacitor 19 is operated as the coupling capacitor and absorbs the unarranged synchronizing signal levels.

Abstract: PURPOSE:To increase the output power of a semiconductor laser drastically in a single transverse mode, by forming the opposite conductivity type semiconductor layer on a one conductivity type semiconductor substrate having a protrusion, and forming a groove which has a depth reaching the protrusion directly above the protrusion. CONSTITUTION:A mesa is formed on p-type GaAs substrate 1 and an n-type GaAs layer 2 grows with a liquid phase epitaxial growth process so that the mesa is filled completely with the above growth. Then, a groove 9 which acts as a current channel is formed on the mesa by etching and a ridge 13 is formed at the outside of the groove 9. The groove is formed in such a way that the inside is narrow but it becomes wider gradually at the nearby end parts. Again, the liquid phase epitaxial growth process allows a p-type GaAlAs layer 3, a GaAlAs layer 4, an n-type GaAlAs layer 5, and an n-type GaAs layer 6 to grow on the groove. Finally, an AuGeNi electrode 7 and an AuZn electrode 8 are vaporized at n and p sides respectively.

SOLUTION: In a reverberation device 10R for a right sound source, a delay circuit 30 repeatedly delays and attenuates the musical sound waveform data of the right sound source at every delay time DT1. Further, the reverberation sound data RVL outputted from a reverberation device 10L for a left sound source is delayed by a delay time DT2 through a delay circuit 31, multiplied by attenuation factor data C, and put together with the input data to the delay circuit 30. In the reverberation device 10L for the left sound, on the other hand, a delay circuit 32 repeatedly delays and attenuates musical sound waveform data SL for the left sound source at every delay time DT3.  Further, the reverberation sound data RVR outputted from the reverberation device 10R for the right sound source is delayed by a delay time DT4 through a delay circuit 32, multiplied by the attenuation factor data D, and put together with the reverberation sound data RVR outputted from the reverberation device 10R for the right sound source. Consequently, the reverberation sound for a right channel contains the reverberation sound component of the left sound source and the reverberation sound for a left contains the reverberation sound component of the right sound source, so that the spread feeling of the reverberation sound is improved.
