摘要:
A male connector (M) is provided with a receptacle (10) and a female connector (F) is provided with a housing (40) that can fit into the receptacle (10) from the front. Mounting grooves (18) are formed by recessing both side walls (16) of the receptacle (10) and fixing members (30) are mounted into the mounting grooves (18). The fixing members (30) are fixed to a circuit board (80) by soldering. Engaging projections (49) bulge out sideways from the opposite side surfaces of the housing (40). Engaging grooves (19) are recessed in the inner side surfaces of the both side walls (16) of the receptacle (10) at positions before the mounting grooves (18) and engage with the engaging projections (49) as the connectors (F, M) are connected to resist a tensile force acting when the housing (40) is pulled away from the circuit board (80).

Terminals connected to wires pass through insertion holes of a holder and the segment holes of a seal member, and are held in the receptors of a connector housing in a state such that the seal member is housed in a recess of a seal setting portion of the connector housing. A pressing portion of the holder containing indents compresses the seal member to thereby reduce the respective sizes of the segment holes of the seal member so as deform the segment holes to shrink in conformity with the outer shape of the inserted wires.

A connector terminal is provided with a press-in portion extending in forward and backward directions; a trunk portion (joining portion) extending downward from the press-in portion; a base portion extending forward and backward from the bottom end (leading end) of the trunk portion, a pair of deflectable pieces for connection (contact portions) which are vertically resiliently displaceable, extend forward and backward from the base portion at the front and rear sides of the trunk portion and have contacts at their sides opposite from the press-in portions; and a leg portion extending upward from the rear end of the press-in portion. The connector terminal is inserted into a corresponding cavity from behind the housing with a leading end of the press-in portion faced forward, and is accommodated and held in the cavity by pressing the leading end into a fixing hole formed in the housing and engaging a hook provided at the leading end with the housing. Contact portions can be effectively prevented from undergoing a deformation (plastic deformation) during the insertion of the connector terminal into the connector housing.

A protective cover B of an electrical terminal is partitioned into an upper cover 50 and a lower cover 40. By doing this, the upper cover 50 and the lower cover 40 can be simultaneously bent prior to fitting. The upper cover 50 has its left and right edges bent perpendicular downwards, the left and right side plates having supporting holes 54 formed thereon. The lower cover 40 has a pair of fitting members 41 and crimping members 42 protruding therefrom, the fitting members 41 having supporting protrusions 43,44 fitting with the supporting holes 54,15 formed on the upper cover 50 and the terminal main body A.

A mold for use in producing a lens comprises a pair of first and second mold portions which are arranged in opposed relation to each other. At least one of the first and second mold portions is movable toward and away from the other. Molding surfaces of the respective first and second mold portions have their respective areas which are located radially outwardly of an effective aperture of the lens. A plurality of recesses are formed in the molding surface of at least one of the first and second mold portions and are located in the area of the molding surface of the at least one mold portion. These recesses separate the lens from the molds.

A semiconductor device having a silicon resistor element is disclosed. The silicon resistor element includes a first polycrystalline silicon film containing oxygen atoms with a low density, and a second polycrystalline silicon film disposed on the first polycrystalline silicon film and containing oxygen atoms with a high density. A silicon oxide film converted from polycrystalline silicon is attached to the top surface of the second polycrystalline silicon film.

A spectacle frame comprises a face-contacting portion such as a side and a lens-fixing portion such as a rim, both the portions being made of a shape memory alloy, and connecting members to be connected with the face-contacting portion and the lens-fixing portion. The connecting member is made of a titanium alloy, preferably .beta.-phase. The face-contacting portion and the lens-fixing portion are soldered to the connecting member with a palladium-based soldering material.

A carburetor is provided with a flow control valve in a fuel discharge passageway leading from an acceleration pump to an air induction passage. The valve is pressure responsive and reduces effective cross sectional area of the passageway in response to pressure in the passageway, the pump discharge pressure.

A construction machine includes: a working equipment; a manipulating unit that manipulates the working equipment; and a controller that controls the working equipment. The controller includes: a rolling compaction determining unit that determines whether or not the working equipment is under a rolling compaction operation for hardening earth and sand through reciprocation; and a command output regulating unit that controls the working equipment so that a motion speed of the working equipment does not exceed a predetermined maximum value when the rolling compaction determining unit determines that the working equipment is under the rolling compaction operation.
