摘要:
In a connector lock structure 1 provided at female and male connectors which can be fitted together, the female connector 2 has an engagement portion 14, and a slide lock member 13 is supported on the male connector 3 so as to move at least in connector-inserting and connector-withdrawing directions. The slide lock member 13 includes a retaining portion 16 for engagement with the engagement portion 14, and urging member 36 for urging the slide lock member 13. When the engagement portion 14 reaches an engagement position where it is engaged with the retaining portion 16 at the time when the female and male connectors are completely fitted together, the slide lock member 13 is automatically moved by the urging member 36, so that the retaining portion 16 is engaged with the engagement portion 14.

A cap nut to be enveloped in a casting made of casting material includes a substantially cylindrical body. The body has a first end and a second end adjacent to a top end surface of the body. The body has a hole and an outer peripheral surface to be enveloped in the casting material. The body has an exposed surface adjacent to the hole at the first end thereof, and the exposed surface is exposed to an outside of the casting. The body has formed in the outer peripheral surface thereof a tapered surface that broadens from the second end of the body toward the first end. The body has formed in the tapered surface a retaining means for preventing the cap nut from falling off from the casting. The body is installable in and removable from a pattern for forming a sand mold at the tapered surface.

A method of making a casting having a cast portion and a cap nut includes forming a hole with a stepped shape in the cap nut to have a large-diameter hole on an opening side and a threaded small-diameter hole on a bottom side, inserting a fixing member into the large-diameter hole, supporting the fixing member in a sand mold, pouring a casting material into the sand mold so that the cap nut is enveloped in the cast portion and that a first surface of the cap nut adjacent to the hole is exposed on a second surface of the cast portion, and removing the fixing member from the cap nut after the casting is taken out of the sand mold.

A composite material includes a thermoplastic resin, and silica glass spheres having a specific surface area of 0.5-10 m2/g. The composite material incorporates the silica glass spheres in an amount of 40% by volume or more. A method of manufacturing a composite material incorporating a thermoplastic resin and silica glass spheres manufactures the composite material which incorporates the silica glass spheres at a compounding ratio determined on a basis of a coefficient of linear expansion of the composite material at a singular point of the thermoplastic resin.

An optical recording medium 10 comprises a disc body 11, a white ink layer 12 provided on the label side 11b of the disc body 11, and an ink receiving layer 13 provided on the surface 12a of the white ink layer 12. The mean roughness (Ra) of the surface 12a of the white ink layer 12 is set not greater than 0.2 μm. A step radially extended is left on the surface 13a of the ink receiving layer 13 and set not greater than 1.0 μm. As the mean roughness (Ra) of the surface 12a of the white ink layer 12 is not greater than 0.2 μm or as the step on the ink receiving layer 13 is not greater than 1.0 μm, high printing quality can be secured when printing is done with an ink-jet printer.

A block distortion reduction apparatus, enabling easy processing by a small-sized circuit configuration and enabling generation of block distortion reduction parameters by any area unit inside a frame, which averages encoding coefficients in a macroblock units to obtain a DCT parameter, calculates a DMV parameter of differential motion vectors by weighting in accordance with the encoding mode of the macroblock unit, and determines a correction value for the block distortion reduction based on these parameters.
摘要:
Management information is read from an information storage medium having the management information recorded thereon, the management information including track number information imparted to at least one track and group management information for managing as selective recording information one or a plurality of tracks as one group. Judgment is then made upon whether the group management information is included in that management information. A display mode is changed depending on a case where the group management information is recorded and a case where it is not recorded, and it is then displayed in a displaying device.

摘要:
The method of mounting an electronic part is capable of securely mounting the electronic part having fine solder bumps without excessively heating the part. The method of comprises the steps of: applying flux-fill, which acts as flux and under-filling resin, on a surface of a mount board, in which electrodes are formed; respectively connecting solder bums of the electronic part with the electrodes; and simultaneously filling a gap between the electronic part and the mount board with the flux-fill, wherein the solder bumps are made contact with the electrodes, and ultrasonic vibration energy is applied to contact portions of the solder bumps and the electrodes in the connecting step.
