摘要:
A terminal fitting has a rectangular tube (10) formed with a locking hole (19). A resilient contact piece (25) is in the rectangular tube (10) for contacting a tab of a mating terminal fitting. Displacement restricting portions (15F, 15R, 18F, 18R) are provided in the rectangular tube (10) at positions before and behind the locking hole (19) for contacting lateral edges of the resilient contact piece (25) and restricting displacement of a resilient contact piece (25) towards a tab entrance space (32). Thus, external matter that may intrude through the locking hole (19) can not cause a damaging deformation of the resilient contact piece (25).

A dummy plug (20) is formed with only one lip (25) having a wide outer surface (26) with a fine undulated pattern (30) that has repeated projections (31) of short height. The projections (31) are disposed to be tangent to a plane. Inclined surfaces (27) are formed at opposite ends of the outer surface (26). The inclined surface (27) guides the dummy plug (20) centrally into a cavity (11) while the outer surface (26) is compressed uniformly and resiliently over the entire circumference. The outer surface (26) closely contacts the inner surface of the cavity (11) due to a resilient force, thereby sealing the cavity (11). The fine undulated pattern (30) decreases the contact area and hence decreases the frictional resistance. Thus, the dummy plug (20) can be inserted smoothly inserted into the cavity (11) with a smaller force.

A linear actuator includes a screw shaft rotatably supported within a housing with play in motion in the axial direction of the screw shaft, and a cushioning stopper disposed between the housing and the screw shaft and elastically deformable to absorb a force acting from the screw shaft to the housing when the screw shaft is forced to move relative to the housing in the axial direction within the range of the play at an abutment of a rod with an obstacle or stopper. When the rod is stopped moving, the motor current increases with the degree of elastic deformation of the cushioning stopper. An overload sensor cuts off the supply of power to an electric motor when excessive current in the motor is detected.

A connector housing (10) has cavities (23) and a retainer insertion hole (27) that crosses the cavities (23). A retainer (30) can be held at a partial or full locking position in the retainer insertion hole (27). The retainer (30) has pairs of resilient locks (33) and fixed locks (35) for the corresponding cavities (23). The resilient locks (33) project into the cavities (23) when the retainer (30) is at the partial locking position while the fixed locks (35) project into the cavities,(23) when the retainer (30) is at the full locking position. The resilient locks (33) are wider than the cavities (23) and hence continue engaging the terminal fittings (10) while the retainer (30) is moved from the partial locking position to the full locking position. Thus, the terminal fittings (10) are locked doubly by the fixed locks (33) and parts of the resilient locks (33) when the retainer (30) is at the full locking position.

Disclosed is a semiconductor device, such as a semiconductor memory device, having structure wherein invasion of minority carriers from the semiconductor substrate into components of the device, formed on the substrate, can be avoided. The semiconductor memory device can be an SRAM or DRAM, for example, and includes a memory array and peripheral circuit on a substrate. In one aspect of the present invention, a buried layer of the same conductivity type as that of the substrate, but with a higher impurity concentration than that of the substrate, is provided beneath at least one of the peripheral circuit and memory array. A further region can extend from the buried layer, for example, to the surface of the semiconductor substrate, the buried layer and further region in combination acting as a shield to prevent minority carriers from penetrating to the device elements. As a second aspect of the present invention, first carrier absorbing areas (to absorb minority carriers) are located between the memory array and the switching circuit of the peripheral circuit, and second carrier absorbing areas are provided to surround input protective elements of the device. As a third embodiment of the present invention, a plurality of isolation regions of the same conductivity type are provided, with unequal voltages applied to these isolation regions, or unequal voltages applied to the substrate, on the one hand, and to these isolation regions, on the other.

A pressure molding apparatus comprises a furnace defining a heating space for accommodating a mold assembly including a mold body charged with a raw material to be molded, and a pressure piston for pressurizing the raw material; heating means for heating the heating space; and load imposing means for imposing a load on the pressure piston to mold the raw material. The load imposing means includes at least one weight means and weight supporting means. The weight supporting means is selectively set in a load-free state in which the weight supporting means supports the weight means so that the weight of the weight means is not imposed on the pressure piston, and a load imposed state in which the weight supporting means releases the support of the weight means so that the weight of the weight means is imposed on the pressure piston.

摘要:
Herein disclosed is a semiconductor integrated circuit device comprising an SRAM having its memory cell composed of transfer MISFETs to be controlled through word lines and drive MISFETs, and a method of forming this device. The gate electrodes of the drive MISFETs and of the transfer MISFETs of the memory cell, and the word lines, are individually formed of different conductive layers. The two transfer MISFETs of the memory cell have their individual gate electrodes connected with two respective word lines spaced from each other and extended in an identical direction. The source line is formed of a conductive layer identical to that of the word line. An oxidation resisting film is formed on the gate electrodes of the drive MISFETs so as to reduce stress caused by oxidization of edge portions of these gate electrodes, and to reduce a resulting leakage current. A thickness of an oxide film formed on gate electrodes of the transfer MISFETs and word lines is thicker than an oxide film formed on gate electrodes of the drive MISFETs, so that data line pads can be formed in self-alignment with the oxide film and side wall spacers on the gate electrodes of the transfer MISFETs.
