Title: Optical fiber splicing terminal and its production
Inventor: TANAKA MASARU
IPC: G02B6/32
Filed: 1986-02-21
Abstract: PURPOSE:To omit optical axis matching between an optical fiber and a lens and their positioning and to splice the optical fiber efficiently to various optical parts by constituting the titled terminal of an installation pipe having a hole with the inner diameter capable of inserting an optical fiber on its center axis and a lens having a recessed part to engage the installation pipe. CONSTITUTION:The head part of the lens 1 is worked like a spherical surface or an aspheric surface and the installation pipe 3 into which the optical fiber 2 is inserted is engaged with the recessed part 1b. Since the tip part of the optical fiber 2 is positioned on the focal position 4 of the lens 1 by working the recessed part 1b so that the focal position 4 of the lens 1 is positioned on the center of the tip part 3a of the installation pipe 3, light beams radiated from the optical fiber 2 are converted into parallel beams. Consequently, the optical axis matching and positioning can be omitted and the optical fiber can be spliced to various optical parts. Since the lens can be molded by a press mold or the like, the terminal can be inexpensively produced with high productivity.

Title: Heating element and manufacture thereof
Inventor: MATSUNAGA HIROYUKI
IPC: H05B3/00
Filed: 1990-02-19
Abstract: PURPOSE:To smoothly move an object to be heated on the surface of a heating element by forming irregularities with the center line average surface roughness Ra 0.1-2mum on the surface of the heating element, and melting the beating surface so that the mesh pattern on the surface of the heating element is not erased. CONSTITUTION:When a heating element 3 is incorporated in an OA apparatus and the required wiring is provided and excited, the heating section 31 of the resistor heating element 3 is heated, and the portion of a protective layer 4 on the heating section 31 is heated. When a heated object with a toner image before fixing is moved in the width direction of the heating element 3 while being kept in direct or indirect contact with the surface of the heating element 3, the contact portion is heated, and the toner image is fixed. Since irregularities 0.0-2mum are formed on the surface of the protective layer 4, the heated object is smoothly moved.

Title: Automatic dispersion compensating circuit and optical transmission system using the same
Inventor: CHIKUMA NAOYUKI
IPC: H04B10/564
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To enable automatic optimum dispersion compensation, even when a necessary dispersion compensation quantity varies when an optical transmission line is switched and to avoid the generation of SSB(simulated Brillouin scattering) which causes a problem when a dispersion compensation fiber is changed. SOLUTION: An optical coupler 32 monitors reflected return light from dispersion compensation fibers 24 and 25 in between an optical amplifier 19 and the preceding stage of the dispersion compensation fibers 24 and 25 and an output control circuit 31 compares the monitor result with the exciting current of an optical amplifier to control the output level of the optical amplifier according to the comparison result. Consequently, the generation of SBS is evaded and optimum dispersion compensation can be performed irrelevantly to the dispersion value of the transmission line.

Abstract: PROBLEM TO BE SOLVED: To insulate the fluctuation of the joint interval of a panel caused by an earthquake or the like and prevent cracks generated in a decorative material by adhering the decorative material on an aluminum substrate plate slidably fixed by crossing the joint part of an ALC panel. SOLUTION: The joint of ALC panels 1, 1 fixed on a steel frame constituting the steel frame of a building is disposed to cross an aluminum substrate plate 2, the screw of a small diameter is inserted through the washer of a large diameter in a large hole 3 provided in the substrate plate 2 to be screwed in the panel 1, and the substrate plate 2 is slidably fixed on the panels 1, 1. A decorative material disposed by crossing the joint of the panels 1, 1 is adhered on the substrate plate 2. In the case where the joint of the panels 1, 1 coincides with the joint of the decorative material, the substrate plate 2 is not used and the decorative material is directly adhered on the panel 1.  Thereby even if the joint interval of the panels 1, 1 are fluctuated by an earthquake or the like, the influence is not transmitted to the substrate plate 2, and occurrence of cracks is prevented in the decorative material in the joint part of the panels 1, 1.

Title: Photomagnetic signal reproducing circuit
Inventor: MATSUI SHOICHI
IPC: G11B11/105
Filed: 1988-02-19
Abstract: PURPOSE:To eliminate the envelope variation of reproduced signals even if the reflectivity of a disk fluctuates so as to make jitter smaller and error rate lower by amplifying the output of a differential amplifier circuit depending on the output of a summing amplifier circuit and using the amplified output as the reproduced signals. CONSTITUTION:The light quantity of polarized light is changed by means of a Kerr rotating angle and an AC voltage is taken out at a differential amplifier circuit 13. Moreover, the whole light quantity is taken out as the output of a summing amplifier circuit 14. When the reflectivity increases, the output of the circuit 14 increases proportionally to the whole light quantity because the whole light quantity increases. In addition, the AC voltage also increases proportionally to the light quantity. When the AC voltage and the output of the circuit 14 are respectively inputted as a numerator and denominator, the increment of the AC voltage proportional to the change in light quantity can be cancelled, and when the reflectivity decreases, the decrement of the AC voltage can be cancelled similarly. Therefore, the level of reproduced signals can be stabilized and envelope variation can be eliminated. As a result, the jitter can be made smaller and the error rate can be made lower.

Abstract: PURPOSE: To prevent the step-out of synchronous machines due to a mistake in operation of the excitation system is the switching, by means of a operation circuit which outputs the control command to vary the set output of the excitation device according to the difference in the outs of two excitation control devices by comparison.  
     CONSTITUTION: When operation is switched from constant excitation control to automatic voltage adjustment, a changeover switch 2 - 5 is changed from the position "constant excitation" to "switching". At this point, the control circuit is turned on with contacts "switching" of an auxiliary relay 2 - 5 and a changeover switch 2 - 3, and then, a control switch is operated to control a variable resistor 1 - 3 for automatic voltage adjustment. When the output of an automatic voltage adjusting device 1 - 1 coincides that of a constant excitation control device 1 - 2, a control relay 1 - 6 works to light an indication lamp 2 - 2. When the switch 2 - 3 is turned to the position "automatic voltage adjustment", an auxiliary relay 2 - 1 works to close a contact 2 - 1a while allowing a contact 2 - 1b to open. With such an arrange ment, remote controlling can be done along with the prevention of the step-out.
