Title: Method for reinforcing fusion spliced part of optical fiber
Inventor: KAJIWARA KENICHI
IPC: G02B6/255
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To stably hold the characteristics of an optical fiber by miniaturizing the reinforcing part of the fusion spliced part of optical fibers. SOLUTION: A heat shrinkable tube 104 or resin tube is constituted to cover the outside of the fusion spliced part 102 of the optical fibers. A UV curing type adhesive 105 is packed between the fusion spliced part 102 of the optical fibers and the heat shrinkable tube 104 or resin tube and is cured by irradiation with UV rays. The heat shrinkable tube 104 is shrunk by heating. The fusion spliced part 102 of the optical fibers is reinforced by curing the adhesive and shrinking the tube in such a manner. The fusion spliced part is thus miniaturized without requiring other reinforcing materials. The packing of the UV curing type adhesive 105 without the formation of air bubbles is made possible by sucking the adhesive into the tube 104 or packing the adhesive therein by capillarity. The characteristics of the optical fibers are thus stably maintained.

Abstract: PROBLEM TO BE SOLVED: To surely perform the fixation of each mounting point of a wiper device, by controlling the rotational moment generated around the line of connecting the mounting points of wiper pivot arranged parts on both sides, by the weight of a wiper motor unit at acceleration of a vehicle. SOLUTION: Since the position G of the center of gravity of a wiper motor unit 7 is roughly in accord with the line L of connecting the mounting points 2P and 3P of the pivot brackets 2 and 3 on both sides, the rotational moment generated around the line L of connecting these mounting points 2P and 3P is suppressed by the weight of the wiper unit 7 at acceleration of a vehicle. As a result, the fixation of the mounting points 2P and 3P of the pivot brackets 2 and 3 and the mounting point 8P of the wiper motor unit 7 are made sure, whereby stability in mounting of the wiper device 1 can be raised further.

Title: Discharging method of a main circuit capacitor in vector-control voltage-type inverter
Inventor: YOSHITAKE NORIO
IPC: H02P27/04
Filed: 1994-12-26
Abstract: PURPOSE: To promptly discharge electric charge from a main circuit capacitor by limiting a speed command for a motor to zero while an inverter is operated. CONSTITUTION: While a speed command of a motor is limited to zero, an operation command for an inverter is turned on, and interlock in inverter operation is canceled. Thus, a vector control voltage-type transistor inverter is operated with an operation command in a zero state, so the motor is operated with only an excitation current factor and no torque current factor in a primary current as an output current from the inverter. A core loss is caused by an excitation current in motor, but electric charge accumulated in a main circuit capacitor is discharged to consume electrostatic energy and compensate the core loss. Next, a discharging timer is always used to check whether a previously calculated discharge time elapses or not. As a result, the inverter and the motor are put continuously in zero-speed operation until the discharge from the capacitor is finished.

Title: Component content estimating method by near infrared spectral analysis
Inventor: FUJIOKA SADAKAZU
IPC: G01N21/35
Filed: 1994-12-26
Abstract: PURPOSE:To reduce a measurement error due to temperature in quantitative analysis by a near infrared spectral analysis method. CONSTITUTION:At the time of obtaining absorbance of a near infrared ray and an analytical curve of a component content, if the temperature dependency of a term composed of dominant wavelengthes is positive or negative, a term composed of absorbances of negative or positive inverse characteristic wavelengthes is used to cancel the temperature fluctuation of absorbance in each wavelength. Thus, a temperature error due to temperature in the component content measurement of an unknown sample by near infrared spectral analysis can be reduced so as to improve the measurement accuracy. In the case of measurement by grinding a sample, though heretofore it is necessary to perform measurement after the ground sample is cooled to the atmosphere temperature, the component content can be measured without cooling.
