Title: Semiconductor laser
Inventor: YOKOYAMA HIROYUKI
IPC: H01S5/00
Filed: 1993-08-26
Abstract: PURPOSE:To provide a semiconductor laser which can generate a high-speed repetitive ultra-short optical pulse train which is useful for optical communication and optical information processing. CONSTITUTION:A semiconductor laser l is a three-section type Fabry.Perot laser which is a three-section two-electrode type device in which two gain sections 2a and 2b are electrically connected to each other. The gain sections 2a and 2b are excited by means of a DC current source 11. The saturable absorption section 3 of the laser 1 exerts its function when a reverse bias is applied across the section from a reverse bias power source 12. When the distances from the center of the saturable absorption section 3 between the two gain sections 2a and 2b to the end faces of the resonator are set at submultiple of the total length L of the resonator, an optical pulse can be generated at the reciprocating period of the shorter distance between the center of the section 3 to the end faces of the resonator. The reason why the laser 1 makes such operations is that the saturated absorbing action is intensified by the superimposition of the optical pulses and stable mode synchronization is generated.

Title: Composite gain control circuit
Inventor: URATA HARUSHIGE
IPC: H04N5/52
Filed: 1994-08-12
Abstract: PURPOSE:To attain high speed response with respect to a signal whose input level changes suddenly and plural burst signals with a rapid level difference by making a direct control gain control function and a feedback gain control function composite to each other and providing a detection function for presence/absence of a signal component to the former function. CONSTITUTION:A variable gain circuit GCf and a level detection circuit LDET form a direct control AGC circuit adjusting roughly the level of an input signal Vin at a high speed. Furthermore, a variable gain circuit GCb, a gain control circuit GCC, a positive voltage limiter LMp limiting the range of an input level and a negative voltage limiter LMm form a high speed feedback AGC circuit. Thus, the high speed processing of AGC is expected. Since the circuit has a function of inhibiting the increase in the AGC gain for a required increase or over especially in the case of soundless signal state, the rising of the AGC circuit in the non-signal state is expected to be quickened.

IPC: F02P3/08
Filed: 1982-12-06
Abstract: PURPOSE:To prevent uneven discharge and electric shock by constituting an igniter for augmenting the firing energy such that a converter will function only during interval including firing timing while employing DC-DC converter. CONSTITUTION:DC-DC converter 7 will function upon turning on of switching circuits 11, 12 while stop upon turning off. A full-wave rectifier 10 will output a signal rectified of signal S1 which will swing to positive side from immediately before firing timing to immediately after firing timing to turn on switching circuits 11, 12 only during said interval. Since DC-DC converter 7 will function only during several tms from immediately before firing timing to immediately after firing timing, it will never cause electric shock even when touching to high voltage section in igniter while keeping a key switch on.
