IPC: G02B6/293
Filed: 1980-03-14
Abstract: PURPOSE:To obtain an easily built-up branching filter which branches and filter lights of many wavelengths by making a prescribed number of holes along the axis of a glass bar, by performing wire drawing with glass bars of high refractive index inserted, and by selecting a prescribed fiber length so that the center wave-directing path and circumferential wave-direction paths will differ in diameter and refractive index. CONSTITUTION:Along the axis of a quartz bar, a prescribed number of holes are made closely to the center part and in those holes, quartz bars (including additives) higher in refractive index than the said quartz bar are drawn to form an optical branching filter which have light directing paths 1-5 arranged in three dimensions inside of fibriform cladding 6. Diameters 2a1-2a5, refractive indexes n1-n5 and length L of wave direction paths 1-5 are selected properly. As light 7 of wavelengths lambda1-lambda5 is incident to wave direction path 1, lights of wavelengths lambda1-lambda4 are emitted from emitting wave direction paths 2-5. Thus, the optical branching filter can easily be obtained which branches and filter many lights differing in wavelength and is easily built in.

Title: Ink tank and recording device
Inventor: TAKAGI ATSUSHI
IPC: B41J2/175
Filed: 1996-02-20
Abstract: PURPOSE: To use ink contained in a capillary tube member to a maximum effective extent by providing a recessed part communicating with an air communicating hole in an internal wall surface in which the capillary tube member incorporated in an ink tank is stored, and forming a space through which air flows, between a recessed part surface and the internal wall of the ink tank. CONSTITUTION: An ink tank 1 consists of a main ink chamber 2 incorporating a capillary tube member 3 and an intermediate ink chamber 4. A lid 13 has a flat surface part opposed to the capillary tube member 3 and a groove 14 with an air communicating aperture 6 which extends in the longitudinal direction, provided in the center. If printing is started, air finds its way into the groove 14 gradually from the aperture 6 and further spreads into the capillary tube member 3 by the consumed amount of ink. In this case, the lid 13 is not pressing the capillary tube member 3, so that the ink held in the capillary tube member 3 moves smoothly in the direction of a first meniscus forming member 8 to reduce the ink residing in the connecting part between the lid 13 and the member 3.  As the amount of the ink decreases, resulting in an increase in the negative pressure, this pressure increase stays within the tolerable limits and therefore, the ink can be supplied by the stable negative pressure on account of a capillary action generated by the capillary tube member 3.
