Title: Clamp system for television receiver
Inventor: UIRIAMU ADAMUSON RAGOONI
IPC: H04N9/64
Filed: 1993-09-17
Abstract: PURPOSE: To prevent an image from flashing by extracting an auxiliary video signal clamp voltage and an AGC reference voltage from a single common bias voltage source and forming their constitution circuits in one integrated circuit. CONSTITUTION: The DC component of the video signal from a tuner 16 is determined by a bias voltage V2 applied to an IF.AGC loop and a bias voltage V3 applied to a video amplifier 64. The DC component of the auxiliary input video signal is determined by a clamp reference voltage V5 and a bias voltage V4 applied to a video amplifier 70. Those bias voltages V2 to V4 and the clamp reference voltage V5 are all supplied from the same reference voltage source 62, so the DC component of the auxiliary input video signal can be equalized to the DC component of the video signal supplied from the tuner. Therefore, a switching transient phenomenon at the time of switching between an internal video signal source and an external video signal source becomes small to reduce the flashing of a screen.

Title: Semiconductor laser device
Inventor: SUZUKI NOBUO
IPC: H01S5/00
Filed: 1989-09-29
Abstract: PURPOSE:To decrease a leakage current and to enhance an optical output when an injection current is at a high level by a method wherein a double-hetero PN junction, a buried PN junction including an active layer, and a sudormorphic layer are provided. CONSTITUTION:A current is trapped in an active layer 3 through a diffusion potential difference between a double-hetero PN junction composed of the active layer 3 and clad layers 2 and 6 and a buried PN junction formed between a second semiconductor layer 6 and a fifth semiconductor layer 5. When a current injection is at a low level, the buried PN junction is not turned ON, so that no leakage current flows. When a current injection is enhanced in level, a voltage applied to the buried PN junction becomes high to enable a leakage current to start flowing. At this point, the pseudomorphic layer 4 functions as a barrier to prevent a leakage current from increasing. By this setup, a leakage current can be decreased and an optical output can be enhanced when a current injection is at a high level.
