A waterproof plug for a waterproof connector, includes a body portion which has a substantially cylindrical shape, and has a first end and a second end which is opposite side of the first end, and an enlarged portion, which is formed on the first end of the body portion in coaxial relation thereto. A slanting face is formed on an outer face of the enlarged portion so that the enlarged portion decreases in a diameter from a side of the second end to a side of the first end.

A semiconductor integrated circuit device has a memory array which includes amplifying MOSFETs of sense amplifiers which amplify small voltages read out of dynamic memory cells onto bit lines and column switch MOSFETs which select bit lines, a read/write section which includes main amplifiers for reading out stored data from memory cells selected by the column switch, and a logic circuit which implements the input/output operation of data with the read/write section. Two capacitors each having a first electrode which corresponds to a plate electrode with the same structure as that of storage capacitors of dynamic memory cells and a second electrode which is multiple commonly-connected storage nodes of the storage capacitors are arranged in serial connection, disposed contiguously to the read/write section, and connected between operation voltage lines of the read/write section.

An opening is defined in an upper portion of a side surface of an instrument panel, such that it is opposed to an air bag module mounted in front of a passenger's seat within the instrument panel. A tray is removably locked in the opening by a locking device. If the tray is removed from the opening, the air bag module is exposed and thus, it is possible for an operator to easily carry out the maintenance operation and the removal of the air bag module in a comfortable position without bending his body.

A ball joint including a housing having two inner chambers in which spherical head portions of ball studs are housed so that the ball studs are swingable, and ball seats interposed between the spherical head portions and the inner chamber walls. The housing is integrally formed of a synthetic resin.The cross-sectional centroid of a central portion of the housing and the cross-sectional centroid of a portion of the housing in the vicinity of each inner chamber are set on the opposite sides of a axial line connecting the two spherical head portions.Annular recesses are formed in the outer circumferential surfaces of the housing, and end flanges of dust covers each having an extreme end portion smaller in contact area in comparison with its base end are engaged with the annular recesses.

摘要:
An outer heat insulating structure on a building roof comprises a plurality of covering layer panels provided with a heat insulating layer and female screw members secured at corner portions in the covering layer panel in alignment with through-apertures provided therein with threaded rods capable of being threadedly engaged with the female screw members. Rubbery elastic members are arranged on a waterproof layer provided on the building roof and members which are secured to the rubbery elastic members and support rotatably lower ends of the threaded rods. A heat insulating layer is defined between the covering layer panel and the waterproof layer.

摘要:
A material comprising crosslinked polyrotaxanes which exhibits desired viscoelasticity, particularly stress-strain characteristics with a wide low-stress region, in spite of being free from solvent; and a process for production of the same. The material comprises a first polyrotaxane bearing first cyclic molecules and a second polyrotaxane bearing second cyclic molecules, and the first and second polyrotaxanes are crosslinked via the first and second cyclic molecules. The material is free from solvent and exhibits a stress of 2.0 MPa or below at 50% strain.
