Abstract: PURPOSE:To eliminate a reading error in read data signal by providing an input selector which selects one output from those of phase difference storing part for address part, of phase difference storing part for data part and of phase comparator, and gives the selected output to the input of a window signal generator. CONSTITUTION:By the input selector 5, at first, the output of phase difference storing part 3 for address part is supplied to the input of window signal generating part 6 in a gap part existing in the interval during the read data signal is transferred to the address part from the data part, then the output of a phase comparator 1 is supplied to the input of window signal generating part 6 when the address part is detected. In a gap part existing in the interval during the read data signal is transferred to the data part from the address part, the output of phase difference storing part 4 for data part is supplied to the input of window signal generating part 6, and next, when the data part is detected, the output of phase comparator 1 is supplied to the input of window signal generating part 6. Thus, the window signal can be corrected to some extent before the address part is detected, thereby the reading error for read data signal is eliminated.

Title: Manufacture of semiconductor laser
Inventor: HORIKAWA HIDEAKI
IPC: H01S5/00
Filed: 1985-05-11
Abstract: PURPOSE:To avoid deterioration of boundaries and facilitate a single mode oscillation by an internal reflective interference effect by a method wherein respective growth layers including the first cladding layer, an activation layer and the second cladding layer are continuously made to grow on the surface of a substrate which has the first and the second grooves in one crystal growth process. CONSTITUTION:The first and the second stripe shape grooves 22 and 23, which make a right angle with each other, are formed on a substrate 21 with a (100) face. Respective growth layers including the first cladding layer, an activation layer and the second cladding layer are continuously made to grow by liquid phase epitaxial growth on the substrate surface including the insides of the first and the second grooves in one crystal growth process without taking the wafer out of or into a growth furnace. When a P-type GaInAsP buffer layer 25 is made to grow on a current constriction layer 24 by liquid phase epitaxial growth, the layer 25 is also made to grow in the first groove 22 of <011'> orientation. Therefore, the first cladding layer 26, an activation layer 27 and the second cladding layer 28 which form double-hetero junction on the layer 25 and generate laser oscillation can be formed within the width of the first groove 22.

Abstract: PURPOSE: To obtain a spiral route to convey parts with less noises by using two pairs of unbalanced weights with different eccentricities to construct vibrating parts.  
     CONSTITUTION: When motors M 1  and M 2  are driven by electricity, shafts 68a and 68b for the first unbalanced weights are rotated conterclockwise via V-belts 80a and 80b. Meanwhile, since large-diameter gears 82a and 82b are engaged with small- diameter gears 84a and 84b, shafts 70a and 70b for the second unbalanced weights are rotated clockwise at double the speed. The first and the second unbalanced weight 72a and 74a on one vibrating part 50a are respectively driven for the same wise rotation with the first and the second unbalanced weight 72b and 73b on another vibrating part 50b. Since they are fixed on their shaft to be mutually opposite by 180 degrees, a bowl 10 is given a torsion to be horizonally vibrated by their periodic motion.
