Dust-proof membranes are provided across both ends of opposite respective divided surfaces defined by halves of wedge guide members. Each membrane has projections formed as an integral unit along the longitudinal side edges thereof. The projections are thrust into longitudinally extending C-shape cross-section grooves formed along the divided surfaces of the wedge guide members. The groove side surfaces are perpendicular to the bottom surface thereof.

Apparatus having a pair of presser cheeks for insertion in a drill hole, with a slider wedge slidably engaged therebetween. The forced descent of the slider wedge by a hydraulic cylinder assembly results in the lateral motion of the presser cheeks away from each other. The presser cheeks are supported from the cylinder body of the cylinder assembly, each via two pairs of parallel spaced leaf springs disposed on opposite sides of the slider wedge and normally closely held against the other two pairs of leaf springs supporting the other presser cheek. While the bottom ends of the leaf spring pairs are rigidly coupled to the presser cheeks, their upper ends are connected to the cylinder body via elastic members yieldable to permit upward displacement of the leaf springs with the presser cheeks, as upon withdrawal of the slider wedge, without buckling. Further two pairs of stop rods depend from the cylinder body so as to normally terminate short of the respective presser cheeks. As the elastic members yield to allow upward displacement of the leaf springs, the presser cheeks come into abutment against the respective pairs of stop rods to prevent the buckling and consequent destruction of the leaf springs.

The present invention provides the technology for burying metal even in a fine concave portion such as trench and via. According to an embodiment of the present invention, a vapor of the metal as the objective material, a gas containing halogen for etching the metal, and a metal halide vapor made up of the metal element and the halogen element are supplied to the substrate, which thus forms a metal halide layer in the concave portion, and thereby deposits the metal under the metal halide layer. The procedure can achieve the above object.

A data processor has sixteen processing elements that each include a register file and an arithmetic logic unit. A network unit connects between the register files of the processing elements and the arithmetic logic units of the processing elements. The network unit has a selector for simultaneously performing a plurality of data transfers which are each made from a register file of one processing element to an operation unit of another processing element. With the provision of this selector that can perform such simultaneous data transfers, the processing efficiency of the processing elements can be maintained even if a change occurs in operand assignments and the like.

The parallel execution processor 100 fetches a piece of instruction data. When the piece of instruction data includes only one instruction, the instruction decoding unit 120 assigns the one instruction to all the PEs. When the piece of instruction data includes two instructions, the instruction decoding unit 120 forms all the PEs into two groups, so as to assign one instruction to each group. By making it possible to execute, in parallel, not only one type of instruction but also instructions that are different from each other, it is possible to improve the utilization efficiency of the parallel execution processor 100.

A semiconductor integrated circuit that acquires an external signal precisely in a high speed operation. The semiconductor integrated circuit includes an internal circuit for acquiring an external signal in response to an address acquisition signal. A first holding circuit is connected to the internal circuit to hold the external signal for a predetermined period in response to a holding signal and provide the held external signal to the internal circuit. A control circuit is connected to the first holding circuit to generate the holding signal using the address acquisition signal.

An internal step-down converter includes a potential difference detector and a cross-coupled amplifier. The potential difference detector detects and amplifies a potential difference between a reference voltage VREF and an internally-stepped-down supply voltage VINT. The cross-coupled amplifier receives the amplified output VDRV2 of the potential difference detector and the output VDRV of a current-mirror differential amplifier, which is applied as a control voltage to a driver implemented as a p-channel MOSFET. The cross-coupled amplifier regulates the amplitude of the control voltage VDRV substantially at the potential difference .vertline.VDD-VSS.vertline. between the external supply voltages. As a result, the load-current-handling capability of the driver can be considerably increased. While the load current ILOAD is relatively small, a control signal generator deactivates the potential difference detector and the cross-coupled amplifier to prevent the current from being consumed in vain. Accordingly, an internal step-down converter with enhanced load-current-handling capability is provided without increasing the layout area or the current consumed.
