A portable disc player has a casing. In the casing, there are enclosed: disc rotation driving means for rotating an optical disc; an optical head which is arranged so as to be movable in the radial direction of the optical disc; a signal processing section for executing a predetermined signal process to a signal which has been read out by the optical head; and control means for controlling the operations of the rotation driving means, the optical head, and the signal processing section on the basis of an input from an X-Y device and trigger buttons. A display unit comprising an outer cover on which an LCD display is arranged is rotatably attached to the casing.
摘要:
A process for producing a spherical zeolite catalyst is disclosed, which comprises dropping a zeolite-containing alumina sol into a surfactant-containing oil phase from a dropping opening directly or through air to thereby form spherical droplets of the sol, and then allowing the droplets to gel in an aqueous alkaline solution phase underlying the oil phase and withdrawing the thus gelled droplets, said dropping of the sol being conducted while the dropping opening is being impulsed to thereby impart a spherical and uniform shape to the resulting zeolite particles containing alumina as a binder, and a novel apparatus therefor.

A high-pressure discharge lamp includes a bulb that is made from glass in which a discharge space has been formed and a pair of electrode assemblies that are sealed in the end portions of this bulb. The electrode assemblies are each provided with an electrode rod for electrical discharge, and the electrode assemblies are sealed in the bulb with one part of each electrode rod extending into the discharge space. The part of each electrode assembly that is sealed in the bulb is in turn enclosed in an intermediate part. This intermediate part has a thermal expansion coefficient that is between the thermal expansion coefficient of the electrode rod and the thermal expansion coefficient of the bulb, is interposed between the electrode assembly and the bulb, and adheres to both the electrode assembly and the bulb.
