摘要:
An optical fiber sheet comprises optical fibers sandwiched between sheet members and fixed thereto. Distal ends of the optical fibers extend from outer peripheral edges of the sheet members with resin coatings applied to the distal ends to produce extensions. The distal ends of the extensions are inserted into fiber holes of connectors with the resin coatings applied to the distal ends to be connected with the connectors.

A multilayer wiring structure of a semiconductor device having a stacked structure is arranged to restrain reliability degradation due to stress applied to the region of wiring between opposite upper and lower plugs. The rate of overlap of contact surface between upper plug and wiring on contact surface between lower plug and wiring, is small to the extent that no void is generated. The multilayer wiring structure is produced such that no grain boundary is contained in the region of wiring between upper and lower plugs. The difference in thermal expansion coefficient between the material of wiring and the material of upper and lower plugs, is small to the extent that no void is generated.

A method for preparing a carbon-containing composition is disclosed which comprises the steps of introducing, into a hot gas, a dispersion obtained by dispersing, in a decomposable carbon compound, a metal oxide and/or a metal compound which can be converted into the metal oxide by heating, to form a carbon-containing composition containing simple carbon and the corresponding metal oxide; and then collecting the formed carbon-containing composition. This carbon-containing composition is useful for the manufacture of a ceramic powder for sintering.

A polymer of a low molecular weight having a very little odor is produced by emulsion-polymerizing a radical-polymerizable unsaturated monomer at a temperature of 115° C. or higher in the presence or absence of a chain transfer agent.
摘要:
A technique and system to enhance the synthesis of solid models from two drawings. The two-dimensional coordinates of a vertex are extracted in each of a top view and a front view and, if their x-coordinates are equal to each other, the combination of their Y-coordinate values is determined to be the two-dimensional coordinates of a candidate vertex in a side view. Then, candidate line segments for the side view are extracted from the line segments connecting two candidate vertices. The process does not extract those line segments for which no corresponding line segment exists in the top and front views and those line segments for which corresponding horizontal or vertical line segments exist in the top and front views, but which are not horizontal or vertical in the side view.

A flexure bearing unit in a linear drive compressor that supports a piston on a yoke for reciprocating movement within a housing includes a plurality of flat discs each provided with a central opening through which extends the piston and a plurality of outer openings receiving parts of the yoke. The flexure bearing is provided with a plurality of first supports each disposed between adjacent flat discs at the outer peripheral portions of the flat discs for supporting opposite sides of the flat discs at the outer peripheral portions of the flat discs. The flexure bearing is also provided with a plurality of second supports each provided between adjacent flat discs at the inner peripheral portions of the flat discs for supporting opposite sides of the flat discs at the inner peripheral portions of the flat discs. The flat discs each include a plurality of spirally extending slits which each possess oppositely located ends. One end of each slit terminates in the outer peripheral portion of the flat disc that is supported on opposite sides by the first supports and the other end of each slit terminates in the inner peripheral portion of the flat disc that is supported on opposite sides by the second supports.
摘要:
A connector apparatus for a card-like data processing medium comprises a frame (12) having opposing side walls (16a, 16b) that define a storage space (24a, 24b) of the connector apparatus. One end of the frame (12) defines an insertion inlet (22) for inserting a card-like data processing medium (30) in the storage space. A header containing a terminal array (32) is coupled to the end of the frame opposite the insertion inlet (22). An ejection mechanism (40a, 40b) is provided for ejecting the card-like data processing medium (30) from the storage space by manual operation of a push rod (48) that is coupled to the ejection mechanism (40). Means responsive to a control signal are provided for automatically decoupling the push rod (48) from the ejection mechanism to desable the ejection mechanism.
摘要:
Gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator therebetween. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers to be a source or a drain of the N-channel transistor are formed using the gate electrode of the N-channel transistor as a mask. After conducting a second thermal treatment to the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment, P-type heavily doped diffusion layers to be a source or a drain of the P-channel transistor are formed using the gate electrode of the P-channel transistor as a mask. Then, a third thermal treatment is conducted to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.
摘要:
A receiver for receiving a broadcast in which data indicating a broadcast station name has been multiplexed to a main signal includes: a receiving circuit constructed in a frequency synthesizer mode; a memory in which a group of frequency data for selecting the broadcast in the receiving circuit, and data on the broadcast station name is registered; a circuit for taking out the data from a signal received by the receiving circuit; a scanner for allowing the receiving circuit to scan the broadcasting zone for the broadcast; and a detector for detecting the received broadcast at the time of the scanning, when the detector has detected the received broadcast during the scanning, the group of the frequency data which has been registered before the start of the scanning, and the data on the broadcast station name is shifted to the data area in the memory, and one group of the frequency data indicating the frequency thus detected, and the data on the broadcast station name for the received broadcast is registered in the data area in the memory which has become empty by the shift.
