Abstract: PURPOSE:To prevent a film from deteriorating and to increase the life of a semiconductor laser by disposing the laser in a groove specified by a pair of sidewalls so as to expose its resonator end face, disposing a target at the opposite position to the end face, and sputtering it. CONSTITUTION:A semiconductor laser 16 is so disposed in one groove 20 as to be disposed between recesses 22 and 22 to which the resonator end faces 17 of semiconductor laser chips 13, 15 are opposed, a target made of Al2O3 is disposed at a position opposite to the end face 17, and high frequency sputtered in an Ar atmosphere. Accordingly, a pair of sidewalls are presented on the peripheries of the end faces 17 of chips 12, 14, and wall faces are not presented on the peripheries of the end faces 17 of the chips 13, 15. Accordingly, Al2O3 of approx. 1650Angstrom  are deposited on the resonator end faces 17 of the chips 12, 14, and Al2O3 of approx. 2500Angstrom  are deposited on the end faces 17 of the chips 13, 15. As a result, the chips 12, 14 can be used as high output type, and the chips 13, 15 can be used as low output type.

Title: Method for checking frequency characteristic of multimode fiber
Inventor: MORI MASAKAZU
IPC: G02B6/00
Filed: 1988-06-17
Abstract: PURPOSE:To make it possible to accurately judge whether or not frequency characteristics is appropriate by inputting the first test signal having a specified frequency into a multimode fiber, and measuring the frequency characteristic value of the multimode fiber at this time. CONSTITUTION:An oscillator 1 is set in a reference frequency signal oscillating mode, and this frequency is transduced into an optical signal. The signal is inputted into a multimode fiber 3 to be measured. The value of a selecting level meter 5 at this time is read. Then, the oscillator 1 is set in an (f) (3dB) frequency oscillating mode. The signal is transduced into an optical signal which is in turn inputted into the fiber 3. The value of the meter 5 at this time is read out. The difference between this value and the value of the meter 5 when the reference frequency signal is inputted is measured. Thus, the frequency characteristic value when the (f) (3dB) frequency signal is inputted into the fiber 3 is measured. Then, the oscillator 1 is set in an (f) (3dB/2) frequency signal oscillating mode. The signal is transduced into an optical signal which is in turn inputted into the fiber 3. The value of the meter 5 at this time is read. The characteristic value is obtained from the difference between this value and the value when the reference frequency is inputted is obtained.

Title: Numerical control system
Inventor: NAGAOKA YUKITO
IPC: G05B19/4155
Filed: 1987-06-17
Abstract: PURPOSE:To apparently shorten the time needed for conversion and transfer and furthermore to omit a large capacity memory for storage of NC sentences by transferring the following NC sentences equivalent to one to several blocks to an NC control part via an automatic programming part during the NC control of a transferred NC sentence. CONSTITUTION:When the NC control is started based on the data produced by an automatic programming part 1, the part 1 converts its produced data into NC sentences by an amount equivalent to one to several blocks and transfers these NC sentences to an NC control part 2. The part 2 performs the NC control based on the received NC sentences. Then the part 1 transfers the next NC sentence equivalent to one to several blocks to the part 2 during the NC control of the previously received NC sentence equivalent to one to several blocks to perform the next NC control after preceding NC control is through. Hereafter such processes are repeated for NC control. Thus it is not required to secure a large memory are for the part 2 and therefore the time needed for conversion and transfer of NC sentences can be apparently shortened.
