A first printed wiring board extends in the vertical direction within a first duct that extends in the vertical direction. A first axial flow fan generates airflow which absorbs heat from the first printed wiring board. Second and third ducts extends in parallel with the first duct. A fourth duct extends between the second and third ducts. A second printed wiring board extends in the horizontal direction within the fourth duct. A second axial flow fan is connected to the third duct. The second axial flow fan generates airflow which absorbs heat from the second printed wiring board. The electronic apparatus can be reduced in size.
摘要:
Air in the first section is allowed to run into a second section through first and second air vents in an electronic apparatus. This causes an increase in the amount of airflow in the first section. In particular, if the pressure loss is larger in the first section, airflow blocked in the first section is forced to run into the second section. A smooth airflow can be established in the first section. Moreover, if the pressure in the first section is set larger than the pressure in the second section, a smoother airflow is established from the first section to the second section. A further superior airflow can be established in the first section.

It is intended to provide the following resin composition for stereolithography which is superior in storage stability and aging stability during operation, shows no increase in viscosity upon prolonged storage, has a high light-curing sensitivity and, therefore, makes it possible to produce, upon photo irradiation, an object by stereolithography, which is superior in dimensional accuracy, fabricating accuracy, water resistance, moisture resistance and mechanical properties at a high fabricating speed and a high productivity. A resin composition for stereolithography which is an actinic radiation-curable resin composition containing a cationic-polymerizable organic compound, a radical-polymerizable organic compound, a photo cationic polymerization inhibitor and a photo radical polymerization inhibitor, in which the photo cationic polymerization inhibitor contains a compound represented by the following formula (I) and having a purity of 80% or higher: wherein M represents an antimony atom or a phosphorus atom; and the broken line between S+ and MF6− represents an ionic bond.

A method and an apparatus for community management in a virtual community are disclosed. The community management apparatus manages a management table as an electronic data containing, in correspondence with each other, the data on a community, the members of the community and the resource data providing the messages exchanged by members, and transfers the resource data from a predecessor community to a successor community. The community management apparatus receives the input of the transfer conditions. The predecessor community selected under the transfer conditions is acquired from the management table. The members corresponding to the acquired community are searched for in the management table and transferred to the successor community. The resource data corresponding to the acquired community is searched for in the management table and transferred to the successor community.

A bellows tube manufacturing method and a system for manufacturing bellows tubes enables composing new mold block trains for molding a bellows tube of a new pattern and sending the new mold block trains into a molding zone without requiring any preparatory operation and without stopping the bellows tube manufacturing system, and manufacturing bellows tubes at high productivity. Elemental mold blocks MBa, MBb, MBc and MBd necessary for composing a first mold block train 20 and a second mold block train 22 for forming elemental molds having molding surfaces conforming to the shape of a bellows tube to be manufactured are selected and arranged according to composition data specifying the numbers, types and order of arrangement of the elemental mold blocks MBa, MBb, MBc and MBd to compose the first mold block train 20 and the second mold block train 22, and the mold block trains 20 and 22 are moved into a molding zone 24. A molten resin is extruded into a space between the mold block trains 20 and 22 moving in the molding zone 24 through an extrusion die 25 by an extruder 26. The corresponding elemental mold blocks MB of the mold block trains 20 and 22 are clamped to form the elemental molds having cavities as the mold block trains 20 and 22 move in the same direction, and a negative pressure is produced in the cavities to mold a bellows tube. The elemental mold blocks MB of the mold block trains 20 and 22 returned from the molding zone 24 are sorted according to type.

摘要:
A method for making a microfine semiconductor device includes the step of forming a diffusion layer of a small depth to provide reduced junction leak current. Si ions are implanted at a dosage of from 1.times.10.sup.15 to 1.times.10.sup.16 cm.sup.-2 into an Si substrate held at a temperature not higher than -40.degree. C. Then, impurity ion implantation into the Si substrate is conducted so as to form an impurity layer having a depth smaller than that of the amorphous layer. Consequently, it is possible to form an amorphous layer wherein elongation and an increase of dislocation loops at the interface between the amorphous layer and crystalline layer is suppressed. It is also possible to activate the impurity layer through annealing and still provide an impurity layer having a depth smaller than that of the amorphous layer.
