摘要:
An optical-electronic integrated circuit device capable of three-dimensionally transmitting optical signals between plural semiconductor substrates on each of which an integrated circuit is previously formed. At least one of the light emitting elements and the light receiving elements are formed on the semiconductor substrate which transmits the light propagated between these elements. In this manner, signals may be transmitted in a direction perpendicular to the semiconductor substrate even without specifically processing the semiconductor substrate. Additionally, signal distortion, transmission losses, mutual intervention or delay are not incurred. For two-dimensionally connecting plural three-dimensionally integrated optical-electronic integrated circuit devices in a direction parallel to the semiconductor substrates, the circuit devices are arrayed on an optical interconnection base plate, and light signals are transmitted by means of a pair of inclined surfaces which are formed on the optical interconnection base plate and which are arranged facing the light emitting element and the light receiving element, and the light waveguide channels defined between these inclined surfaces. This drastically increases the operating speed of the circuit device and the integration degree.

A structure of a fireproof frame for building opening portions wherein a groove is formed over the entire circumference of a wood frame, which is disposed to a building opening portion, at the surface abutted against an opening member. A non-combustible heat forming sealing material is filled in the groove and the surface of the sealing material is covered with a thin film, which is excellent in heat conductivity, by means of the self bondability of said sealing material.

A process for separating basic amino acids from a liquid containing the same using cation exchange resin towers in series, which comprises effecting repetitive adsorption and elution steps in sequence, wherein the washing water employed in said adsorption and elution steps is obtained by recycling the latter portion of a liquid discharged from a first tower of the adsorption step into an adsorption step in a subsequent cycle, or by recycling a liquid discharged from a first tower at the elution step into an elution step in a subsequent cycle.
摘要:
A method for separating a basic amino acid from its fermentation broth, or the liquid resulting from the intermediate treatment of the fermentation broth, containing high-molecular weight contaminants which entails permeating the broth, or liquids resulting from the intermediate treatment of the broth, through a semi-permeable membrane, until the basic amino acid is separated from the high-molecular weight contaminants, by passing through the membrane in the permeate; contacting the permeate with a strongly acidic cation exchange resin; and eluting the adsorbed basic amino acid from the cation exchange resin.

A method for treating a steel slab containing 2.5 to 4% Si to a temperature not lower than 1260.degree. C. in a continuous heating furnace of the walking-beam type, comprising; charging the slabs into the continuous heating furnace through its charge inlet, transferring the slabs by means of walking-beams in the furnace with the rear end of a preceding slab substantially contacting a front end of a subsequent slab under the condition that the contact time of the slab with fixed beams is not more than three times longer than the contact time of the slab with the transfer beams, and separating the adjacent slabs with a space sufficient to permit remelting of solidified slag adhered between the adjacent slabs approaching the extraction outlet of the furnace.

A coil-type electronic component has a coil inside or on the surface of its base material and is characterized in that: the base material is constituted by a group of grains of a soft magnetic alloy containing iron, silicon and other element that oxidizes more easily than iron; the surface of each soft magnetic alloy grain has an oxide layer formed on its surface as a result of oxidization of the grain; this oxide layer contains the other element that oxidizes more easily than iron by a quantity larger than that in the soft magnetic alloy grain; and grains are bonded with one another via this oxide layer.
