    摘要: A printer includes a cutting apparatus with a shield that protects the cutting part of a cutter blade in the apparatus. A fixed blade is supported so that the fixed blade can be moved by pressure by a compression coil spring upon a fixed blade supporting frame attached to a body frame so that the fixed blade supporting frame can be opened or closed. A blade cover for protecting the cutting part of the fixed blade is fixed to the fixed blade supporting frame. When each fitting between fitting parts of the fixed blade and touching parts of a cutter frame is released in a state in which the fixed blade supporting frame is open, a part or the whole of the cutting part of the fixed blade is shielded by the shielding part of the blade cover.

    摘要: A printer and an ink tank for the printer capable of precisely detecting that ink has run out in a foam type ink tank. The ink chamber and an ink passage are formed in this order between the foam containing portion and the ink outlet of a foam-type ink tank. A first filter is installed between the foam containing portion and the ink passage and used to pass bubbles therethrough, whereas a second filter having a pore diameter smaller than the pore diameter of the first filter is installed between the ink chamber and the ink passage. A rectangular prism for detecting an ink end is formed on the side of the ink chamber. When the reflective surface of the rectangular prism is exposed from an ink liquid level as bubbles are gathered in the ink chamber with ink that is running short, light is reflected from the reflective surfaces and is detected by a reflection type optical sensor on the ink-jet printer side, so that the ink end can be determined. In a case where the capacity of the ink chamber is set sufficiently smaller, the ink end is detectable at a point of time when the ink has substantially run out.

    摘要: A ridge waveguide-type optical semiconductor device and a method of fabricating the same. The method of fabrication includes forming a first clad layer, a core layer, a second clad layer and a contact layer, in the stated order on a semiconductor substrate, forming a strip-shaped etching mask on the contact layer, removing the contact layer and the second clad layer selectively by etching, using the etching mask, until the core layer is exposed, so as to form a ridge including etched second clad layer, and forming a semiconductor layer by crystal growth, so as to form a mode control layer on the exposed surface of the core layer. The semiconductor device includes a semiconductor substrate, a first clad layer formed on the substrate, a core layer serving as a waveguide, on the first clad layer, and a strip-shaped second clad layer on the core layer. A mode control layer is formed on the core layer, and insulating layers are formed on the mode control layer, at opposite sides of the second clad layer. To confine light to waveguide, the mode control layer has a refractive index equal to or less than a refractive index of the core layer, and is larger than refractive indexes of the respective insulating layers.
