Abstract: PURPOSE:To provide an apparatus for producing a fiber ribbon coupler capable of lessening deviation in the central positions of pairs of bare fiber parts in groove parts to be inserted with the bare fiber parts and applying adequate pressing force to the pairs in the respective bare fiber parts. CONSTITUTION:The groove parts 13a to 13d formed in a main body member 11 of a bare fiber part fixture are formed to a V shape in their bottoms. Among the pairs of the bare fiber parts inserted into the respective groove parts, the bare fiber parts on the lower side can be positioned at the center and the deviation in the central positions of two pieces of the bare fiber parts is lessened. Pressing members are so supported by supporting members 14 as to be movable vertically and are held energized upward by spring members 16. Then, the uniform pressing force is applied to the pairs of all the bare fiber parts even if the pairs of the bare fiber parts inserted into the groove parts 13a to 13d are nonuniform in height.

Title: Amplifier
Inventor: ENDOU KOUICHIROU
IPC: H03F1/02
Filed: 1980-10-17
Abstract: PURPOSE:To increase the efficiency of amplifiers provided with DC-DC converters, by changing the power supply voltage of an amplifiers according to an input signal. CONSTITUTION:An input signal from an input terminal 9 is rectified and integrated at a rectification and integration circuit 1 to form an envelope signal for the input signal. This signal is compared with the output of a DC-DC converter 4 at a comparator 2, and the output is given to the pulse width modulator 3 being a control voltage. A pulse train with different pulse width is produced according to the control voltage of the modulator 4 to perform on/off control for switching elements of the converter 4. Thus, the output voltage of the converter 4 is increased or decreased in proportion to the envelope signal of the input signal. This voltage is applied as the power supply voltage of an output stage connected to a preamplifier. Since the power supply voltage of the amplifier is changed according to the input signal, the efficiency of the amplifier can be increased.

Abstract: PURPOSE:To speed up the measurement of thickness of a sample by Fourier transforming, the power spectrum data, finding the period of variation in the intensity of the power spectrum, and calculating the thickness of the sample from the found frequency. CONSTITUTION:When a transmission trigger is outputted from a pulse control part 20 to a pulse transmission part 10, the transmission part 10 generates a single-shot pulse.

Abstract: PURPOSE:To decrease the sticking of a scattered material without installing an object to be worked in a reduced pressure chamber by arranging a vacuum chuck on a working table so that it coincides with an elimination pattern or goes to a shape including the whole pattern. CONSTITUTION:First of all, a substrate 2 on which a stainless steel thin film is formed is placed so that the surface of an object 3 to be worked is opposed to the surface of a table 4. Subsequently, before a YAG laser beam 1 is condensed and irradiates the substrate, the opening/closing of a solenoid valve is controlled by a control 10 so that only the solenoid valve 8 connected to the suction part of an irradiated part goes to an open state. After one piece of pattern is formed by radiating the YAG laser beam, the solenoid valve is switched, while the laser beam 1 moves to the next pattern part, and as soon as the vacuum exhaust capacity of the next pattern part is increased, the solenoid valve connected to the pattern part of the previous process is closed and only a bypass is in a suction state. Thereafter, by repeating it, a linear separation pattern is formed. The peripheral scattered material is scarcely stuck to this pattern.
