An optical fiber cable and a tight-buffered optical fiber which suppress an increase in transmission loss in a humid and hot environment and have good manufacturability are disclosed. The tight-buffered optical fiber of the present invention comprises a glass fiber surrounded by a first coating layer and a second coating layer, the second coating layer comprising two or more layers; wherein a pull-out force is 15 N/20 mm or less in at least one pair of layers between the first coating layer and the second coating layer, or between any two layers of the second coating layer.

Tight-buffered optical fibers and optical fiber cables

There are provided an optical fiber ribbon and optical fiber cable which suppress the deterioration of polarization mode dispersion and contribute to the increase of communication capacity in wavelength division multiplexing. An optical fiber ribbon includes a plurality of optical fiberstied in a bundle and a ribbon coating layerformed around the plurality of optical fibers to integrate the plurality of optical fibers, wherein the glass-transition temperature of the coating ranges from 80&#xb0; C. to 130&#xb0; C. and 'a' is 0.01 mmor less, where 'a' is a sectional area of the ribbon coating layerin a cross section in which outer half of the optical fiber at an edge of the ribbon and the coating of the optical fiber ribbon are taken along a line passing the center of the glass optical fiber positioned at one of edges of the ribbon out of the plurality of the optical fibers and being perpendicular to the horizontal plane of the optical fiber ribbon.

Optical fiber ribbon core and optical fiber cable

An information processing apparatus includes an input portion for inputting information, a recording portion capable of recording information input by the input portion onto a recording medium and a moving mechanism capable of vertically moving the recording portion and holding the recording portion at a predetermined position.

Information processing and recording apparatus with two recording medium

A printing apparatus system includes a plurality of type units each having a plurality of type elements and each being different from the others. Each type unit may be mounted in the apparatus. A detector detects which of the type units is so mounted and produces a detection signal representative thereof. The printing pressure with which each type element is imprinted on a print medium is determined in accordance with the particular type wheel mounted in the apparatus as indicated by the detection signal. Additionally, the amount of advance of an ink ribbon for imprinting a type element on a type unit is determined in accordance with the particular type unit mounted in the apparatus, again as indicated by the detection signal.

A recording apparatus has a memory for storing information entered from a key input device, whereby the stored information can be used to rapidly and precisely position erasing means at a previously recorded indicium for erasure thereof. The apparatus may also have at least one drive system which controls the printing pressure, the amount of printing ribbon feeding, or the amount of printing sheet feeding, and a memory for storing information to regulate the drive systems. One embodiment of the apparatus is an electronic typewriter.

An improvement in movement of the recording section in a recording apparatus such as a typewriter, a printer or the like is provided. This recording apparatus comprises: a print ribbon cassette having a recording material; a carriage having a solenoid or a cam for moving the cassette; a detector for detecting the vertical or horizontal moving amount of the cassette; and a controller for controlling the moving condition of the cassette moved by the carriage on the basis of an output from the detector. The moving time of the ribbon cassette is changed in accordance with the typing speed of the operator or the size of character to be recorded. Thus, the whole printing time can be shortened and the noise generated in association with the typing operation can be reduced.

Recording apparatus having an improved mechanism for moving the

A printing apparatus includes a print wheel having a vertical lien character, a minus symbol character, and an underline symbol character. A first control moves a carriage on which the print wheel is mounted at one of two pitches and a second control advances a printing paper for receiving printing at one of two pitches in a direction generally perpendicular to the direction of movement of the carriage. Respective keys select the vertical line character and underline character for printing and the printing and paper-advancing pitches. One key signals repeat actuation of either the key selecting the vertical line character or the underline character and a memory stores actuation of the key for selecting the vertical line character. Printing of a vertical line character and advancement of paper is achieved by a control in response to actuation of the repeat signaling key, if the memory stores actuation of the vertical character key. Another control clears the memory in response to operation of any key other than the repeat signaling key.

Printing apparatus including error correction and memory means, for

A printer has a memory containing print information on a plurality of characters, grouped by a print pressure of the character, and a control unit for controlling the print pressure in accordance with the print information stored in the memory. The memory stores the print information for each print pressure group in ascending order. The duration of the impact pulse is determined once the character's code is found in the list of characters stored in order of lowest to highest impact energy, based on character size.

An electronic apparatus for drawing up documents. The apparatus includes an indicator for indicating registration of information, a keyboard for entering indicia and print pitch information, a memory including a first area for storing keyboard information, a second area for storing entered print pitch information, and a third area for storing registration information according to an indication by the indicator. The apparatus further includes a controller for, in response to the registration indication, storing the indicia information stored in the first area and the pitch information stored in the second area in the third area.

Serial printing apparatus with controllable pitch

An improved ink ribbon cassette for a serial printing apparatus comprises a body, first and second substantially coextensive spaced ink ribbon guide arms projecting from the body, each having a free end, and an ink ribbon mounted in the body for advancement during printing and having a portion extending between the free ends of the guide arms so as to be available for printing. One of the guide arms has a window therein through which the ribbon is visible. A first optically detectable indicator is carried on the ribbon at a position to be visible through the window when the ribbon is substantially exhausted. A second optically detectable structure is mounted on the guide arm adjacent the window and laterally spaced therefrom in the direction of movement of the ribbon. This second optically detectable structure indicates the type of ribbon in the cassette.
