  • Patent number: 5478158
    Abstract: There is an output apparatus which prints and outputs onto an ink ribbon in an electronic typewriter or the like. This output apparatus comprises: an output head to output a desired character through an ink ribbon; a cassette in which the ink ribbon is enclosed; a guide device to move the ink ribbon pulled out of the cassette in the direction having an angle of inclination with respect to the vertical direction; and a control unit to control the ink ribbon feed mechanism so as to stop the advance of the ink ribbon such that the length of ink ribbon pulled out of the cassette is made almost constant before and after the movement of the ink ribbon by the guide device. One motor is commonly used for print paper feed, ribbon feed, and ribbon lift up/down operations. The type wheel having a plurality of type elements is bilaterally rotated and its rotation amount is properly controlled to detect the home position of the wheel.

  • Patent number: 5329600
    Abstract: In an optical fiber coupler fabricating process where couplers are successively formed by heating, elongating and cutting a plurality of long optical fibers, light is led into the first end of the fiber, reflected at the second end of the coupler, and the reflected light is monitored by photodetectors. In this manner, an exact splitting ratio can be obtained. Techniques for minimizing measuring errors caused by the inter-reflected-light interference, the inter-Rayleigh-scattering-light interference, and the interference between the reflected light and the Rayleigh scattering light, while exploiting the advantageous feature of the reflection monitor method that the fiber connection work for each fiber coupler fabrication is not required are disclosed.

  • Patent number: 5257869
    Abstract: In a typewriting apparatus in the invention, the carrier is driven by a stepping motor. Characters printed by this apparatus are divided into two groups, one for characters frequently used but requiring no higher printing position precision and the other for characters less frequently used but requiring higher printing position precision. Furthermore, each group can be printed in a normal printing mode or in a boldface printing mode. These four kinds of printing are executed by selecting their respective suitable pulse rates of the stepping motor.

  • Patent number: 5247598
    Abstract: A reinforcing apparatus for an optical-fiber coupler is formed by placing fused optical fibers into a grooved U-shaped base structure. A cover which has a different longitudinal length than the base structure is centered on top of the U-shaped base structure. There exists an exposed groove section of the U-shaped base structure which lies on either side of the cover. An adhesive is inserted into these exposed groove sections so as to fix the reinforcing casing and the optical-fiber coupler to each other.
