Title: Semiconductor laser drive method, drive signal generator for semiconductor laser, signal superimposing device, transmitter and signal generator
Inventor: KAWAMURA HIROMITSU
IPC: H04B10/2507
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce temary interconversion distortion by using a drive signal resolution from superimposing a main signal that results from a carrier subject to intensity modulation by transmission information and a sub-signal that is modulated by a frequency within a specific band so as to drive a semiconductor laser. SOLUTION: First and second stations 2, 3 modulate carries of 800MHz, 806MHz by a transmission signal respectively to generate a main signal and it is fed to a superimposing section 4. The superimposing section 4 superimposes the main signal to generate the drive signal, which drives a light emitting device 4 consisting of a semiconductor laser to allow the device 4 to emit a laser bean subject to intensity modulation. The laser beam is received by a reception section 6 via a single mode optical fiber 5 with a length of, e.g. 25km. A sub-signal generating section 7 generates a sine wave of a proper frequency in a range of 200-400kHz and the superimposing section 4 superimposed the sine wave onto the main signal. In this case, the modulation of the sub-signal is set to a range of 1 to 20% of the carrier of the main signal.  Then the spectral width of the semiconductor laser is spread to prevent the inductive Brillouin scattering.

Filed: 1991-04-22
Abstract: PURPOSE:To manufacture the lead frame which scarcely generates a lead shift and has no flaw in the internal lead by forming in advance a groove in the part in which punching is executed, and negating the lead shift at the time of forming the internal lead. CONSTITUTION:To the root part of an internal lead 14 of the part which becomes a slug, a groove, desirably, a groove 16 whose cross section is a V- shape is formed before punching. A stock in the vicinity of the groove is spread out to the outside around the groove, and to the part which becomes an internal lead, a strain turned in the direction as indicated with an arrow A is given in advance. In the case punching is executed without forming the groove, the internal lead moves in the direction as indicated with an arrow B. Accordingly, by giving in advance a strain in the direction reverse to the moving direction at the time of punching to the internal lead, the motion of the internal lead at the time of punching is negated, and a lead shift is relaxed.

Title: Reproducing device for color video signal
Inventor: NARITA TAKAHITO
IPC: G11B20/02
Filed: 1986-05-23
Abstract: PURPOSE:To control the hue of reproducing chrominance signal by replacing a burst signal in a carrier chrominance signal with a signal outputted from a crystal oscillator and controlling a phase with a variable delaying circuit. CONSTITUTION:The carrier chrominance signal from a frequency converter 5 is supplied to a semi-fixed variable delaying circuit 11. The delaying quantity of the variable delaying circuit 11 is adjusted by a variable resistance 12. When the delaying quantity of a variable delaying circuit 14 is larger than the central value, the phase of the burst signal replaced in a switch circuit 13 is delayed from the phase of an original burst signal, and reversely, when the delaying quantity is smaller than the central value, the phase is advanced against the phase of the original burst signal. Since the carrier chrominance signal outputted from the switch circuit 13 is color-demodulated by a color subcarrier coincident to the phase of the burst signal, the hue can be adjusted by changing the phase of the burst signal.
