Title: Fixing system for oscillation wavelength of semiconductor laser array
Inventor: FUBU TAKUMI
IPC: H01S5/40
Filed: 1980-06-14
Abstract: PURPOSE:To fix plural oscillating wavelengths in the wavelengths range of about 50Angstrom  by deciding a wavelength by two-dimensional quantity wherein a difference in laser wavelength is sufficiently shortened at an interval of about 100mu by an easily available low dispersion optical system. CONSTITUTION:Laser 1 light on the focus surface 20 of a collimator 4 is composed as parallel light along a plane surface 13 to feedback to the laser 1 by diffracting and reflecting by a diffraction grating 5 and a plane mirror 6. Therefore, an oscillating wavelength lambda1 is fixed by a plane angle of incidence alpha and a plane angle of reflection phi, and grating constant d and the oscillating wavelength lambdan of the nth laser is generally fixed to 2dsinalphancosphin when the nth laser light arrives at the diffraction grating 5 at an angle of incidence alphan and an angle of reflection phin. Therefore, the oscillating wavelength is decided by 2 two-dimensional quantities of phin1, alphan to increase the degree of freedom and efficiency is increased if phin is selected at around a blazed angle. In this composition, a light source for multiple wavelength optical communication with practicality can be obtained by using given laser array regardless of the dispersion value of the dispersion optical system and by fixing the oscillating wavelength of the laser in the array at an arbitrary value.

Title: Automatic voice return telephone set
Inventor: GOMI KAZUHIRO
IPC: H04M1/66
Filed: 1990-03-30
Abstract: PURPOSE:To detect the end of talking without losing the rebuffing effect to a troublesome phone call by extending an utterance end detection time longer than a pause time of a lockout tone when it is discriminated that a recorded voiced block corresponds to an ON period signal of the lockout tone. CONSTITUTION:While the result of voiced/unvoiced tone discrimination is discriminated to be a voiced tone, a read value Vin from a line signal level detection section 11 is compared with level threshold values V1,V2. Zero cross number threshold values Z1, Z2 are selected so that a fundamental signal frequency of the lockout tone measured by a zero cross counter 12 stays between the threshold values Z1, Z2. In the case of the establishment of the relation of Z1<=Zin<=Z2 when the relation of V1<=Vin<=V2 exists, it is discriminated that a ON period signal of the lockout tone comes. Thus, a line acquisition invalid time is reduced after the talking opposite party terminates its talking without losing the rebuffing effect to a troublesome phone call.
