Filed: 1988-01-06
Abstract: PURPOSE:To eliminate the need of transmitting a discriminating signal from an optical wavelength multiplexing circuit in order to take out a detection signal by bringing an input light to frequency modulation by a first discriminating signal, and also, bringing it to amplitude modulation by a second discriminating signal. CONSTITUTION:In an optical wavelength multiplexing circuit 100, a wavelength multiplex optical signal is brought to frequency modulation by a first discriminating signal whose frequency is lower than input data which is determined in advance at every wavelength of light, and also, an input data signal is brought to amplitude modulation by a second discriminating signal.

Title: Manufacture unit for semiconductor device
Inventor: YAMAGUCHI TETSUJI
IPC: H01L21/58
Filed: 1981-01-10
Abstract: PURPOSE:To eliminate dispersion in the thickness of solder solidified immediately beneath an semiconductor element on a substrate by a method wherein a support holding a collet travels back and forth, and up and down, and the lowering  of the collet is halted by a lower limit stop. CONSTITUTION:A semiconductor element 1 is attractedly attached to a collet 2 that carries the element 1 toward a substrate 4 on which a semiconductor device is to be prepared, when a support 3 is caused to travel forward. The support 3 and the element 1 go down and the element 1 comes in contact with molten solder 5. A stop 6 is abutted against by the lowering support 3, preventing the support 3 from lowering further and thereby ensuring a gap (t) between the element 1 and the substrate 4. Rocking back and forth of the support 3 causes the oxide film to be removed making an active surface of the molten solder expose, while the element 1 is fixed on the substrate 4. The thickness of the solidified solder is approximately equal to the gap (t) and the products are free of thickness dispersion.

Abstract: PURPOSE:To reduce man-hour for writing servo information and also to improve the yield of a medium by detecting the defect position of a medium beforehand and writing the servo information in an area which is kept out of the defect area of the medium as much as possible. CONSTITUTION:A positional information in the track direction of a disk medium 8 is detected by a means 3 to detect track positions, and a positional information in the peripheral direction of the disk medium 8 is detected by the means 4 to detect peripheral positions.
