An apparatus for preparing a coffee beverage by supplying the ground coffee beans fed from a coffee mill for grinding coffee beans to an extractor to prepare the coffee beverage is disclosed, wherein a device for removing the silver skins out of the coffee beans ground by the coffee mill is provided therewith.

Apparatus for preparing a coffee beverage

A deodorant containing an azo metal complex expressed by the following structural formula 1, which is produced by mixing a solution in which azo compounds to be ligands are dissolved with a solution in which a metal salt is dissolved: ##STR1## In the structural formula 1, M represents a metal element, R.sub.1 and R.sub.2 represent aromatic compounds, which may be the same or different from each other, and R.sub.3 and R.sub.4 represent aromatic compounds or heterocyclic compounds, which may be the same or different from each other. In addition, either one or both of nitrogen atoms in an azo base in each of the legends may be coordinated to the metal M.

Deodorant method

A surface acoustic wave device comprising a single crystal silicon substrate and a piezoelectric thin film of single crystal or C-axis-oriented polycrystalline aluminum nitride formed on the surface of the substrate. The C-axis of the piezoelectric thin film is set in a direction in which the projection vector of the C-axis on a plane containing the axis of propagation direction of a surface acoustic wave and a normal axis of the substrate makes an inclination angle .theta. of up to 60 degrees with the axis of propagation direction, whereby the device is given a coupling coefficient of at least 2% is given as maximum coupling coefficient of the device.

Surface acoustic wave device

A liquid crystal chopper comprising a pair of electrically conductive substrates, a spacer keeping the substrates so as to define a space between the substrates, and a liquid crystal of DSM type which is enclosed in the space, with a dielectric anisotropy of -0.5 or more and not exceeding 0. An infrared sensor using the liquid crystal chopper in the above construction as a chopper mechanism to intermittently interrupt infrared rays incident upon the pyroelectric element. The infrared sensor has a short response time at the liquid crystal chopper and consumes less power.

Liquid crystal chopper and infrared sensor

An optical wavelength converting device includes a substrate, and a waveguide layer of a nonlinear organic material formed on one major surface of the substrate and having a thickness tapered along one axis parallel to the major surface, in which a waveguide with a desired thickness can be selected in a direction normal to the axis.

Optical wavelength converting device and manufacturing method thereof

A focus adjusting apparatus comprises a focus lens device provided in an optical system. The focus lens device comprises a transparent container of a rectangular prism form, a lens member supported in the container and formed of poly(acrylic amide) gel as a polymer gel substance having electro-reactive deformability, and a pair of transparent electrodes, the container being filled with water-aceton mixture solution. The lens member is formed by two lens materials having different proportions of acrylic acid group. A voltage is applied to the transparent electrodes under control of an automatic focusing circuit to cause electric field in the container, whereby the lens member is deformed in a concentric spherical form to form a lens. When the application of the voltage is stopped, the lens member returns to the initial form. A focal distance of the lens member is changed according to degrees of such deformation of the lens member.

Focus adjusting apparatus provided with a focus lens member formed of

An ultrafine tube is produced by a method comprising the steps of applying a highly polymerized material on a substrate to form a resist layer on a surface of said substrate, applying a laser beam to the resist layer under such a condition that said resist layer is melted to form an ultrafine tube between the substrate and resist layer in the predetermined pattern.
