Abstract: PROBLEM TO BE SOLVED: To reduce the noise factor of optical pulses filtered by an optical filter by controlling the optical intensity of excitation pulsed light made incident on an optical waveguide type nonlinear medium. SOLUTION: Excitation pulsed light generated in an excitation pulse light source 1 is made incident on an optical waveguide type nonlinear medium 2, and generated white pulsed light is filtered by a wavelength filter 3, and optical pulses of a specified wavelength are outputted. And, this pulsed light source is provided with an optical branching part 6 for branching a part of the light intensity of the excitation pulsed light, a light intensity measuring part 7 for measuring the branched excitation pulsed light intensity, and a light intensity control part 8 for controlling the excitation pulsed light source 1 so that an excitation pulsed light intensity measured by the light intensity measuring part 7 is to be a desired value.  However, a relation between the excitation pulsed light intensity and a noise factor in white pulsed light generation is measured beforehand, and based on the relation, an excitation pulsed light intensity with which a noise factor to a wavelength to be filtered by the wavelength filter 3 becomes small is preset as a target value.

IPC: B31B50/02
Filed: 1980-06-18
Abstract: PURPOSE: To prevent possible elongation or the like with a less tensile force working on the sealing section by providing a vertically movable film support at the upstream of a film holder before and behind a heating mechanism.  
     CONSTITUTION: A tubular resin film 2 is intermittently withdrawn with a take off roller 9 and heat welded with a heating mechanism 7. In a bag making machine of such a type, a film holder 8 is provided before and after the heating mechanism 7 to work the film 2 at the heat welding thereof. A vertically movable film support 6 is provided on the upstream of the film holder 8 in such a manner as to move roughly vertical to the transfer surface of the blank film 2 for heat welding and return to the original position after the welding. This makes it possible to store the film by a necessary length for the subsequent pitch as slackened thereby reducing the tensile force working on the sealing section 13.

Title: Repeater for ofdm
Inventor: SUGA TAKU
IPC: H04B7/15
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To provide an OFDM use repeater where the adjustment is easy and the characteristic of a transmission channel subject to change in seasons, weather and time can adaptively be compensated. SOLUTION: A compensation quality detector 2 sequentially converts an RF input signal into an IF signal, a base band signal, and a frequency base signal to extract pilot signals at an interval of subcarriers arranged on a frequency base. Since the pilot signal for each subcarrier appears at a prescribed symbol period, interpolation processing is applied thereto in the direction of the time base. The amplitude phase characteristic in a transmission frequency band can be obtained by detecting the amplitude and phase characteristic of the pilot signal with a symbol period in each subcarrier obtained in this way. A signal with a characteristic inverse to this characteristic is generated and used for a compensation signal to compensate (3) the amplitude and phase characteristic of an IF signal that is a main signal.
