The present invention provides a multi-input A/D converter circuit capable of shorting a conversion time without increasing its layout area and current consumption. When a most significant bit of a binary counter is "L", individual input signals are sampled by a sample and hold unit, and digital signals held in respective data holders are sequentially selected by a selector. When the most significant bit is brought to "H", the respective input signals are held as analog signals and compared with...

A memory-logics LSI device forms an input/output path for testing. A memory device has a memory input/output unit,which includes an input/output selector with test function. A test clock signal, which is directly supplied in the test mode, is used to selectively take in one of input signals and an output signal to output the signal. The output is monitored on an external pin, while changing the timing of the positive-going edge of the clock signal, or the input signals. Relative measurement is t...

A multi-layer bus system includes an interconnect matrix, bus slaves, bus masters and a bus control circuit. The interconnect matrix has master connection ports and slave connection ports, and connects one of the master connection ports to one of the slave connection ports in response a control signal. The slaves are connected to the slave connection ports, respectively. The bus masters includes a priority bus master connected to one of the master connection ports and a non-priority bus master. ...

A retractable roof includes a front roof panel, a back roof panel formed by joining outer and inner panel layers to each other, a lower link pivotally connected to a vehicle body member, an upper link pivotally connected to the front roof panel, and an intermediate link rigidly connected to each of the lower link and the upper link. The intermediate link is placed in between the outer and inner panel layers of the back roof panel.

A voltage controlled oscillator includes a resonant circuit, a trimming capacitor and a full adder. The resonant circuit includes a negative resistor, an inductor and an oscillation frequency setting capacitor having a variable capacitance according to a controlled voltage based on a oscillation frequency data. The trimming capacitor is connected in parallel to the oscillation frequency setting capacitor. The trimming capacitor has capacitors each of which has a variable capacitance according to...

A hollow cylindrical pulley body 5 is carried rotatably by a hollow cylindrical shaft member 11. A support rod 8 is inserted in the shaft member 11, and the shaft member 11 is elastically supported to the support rod 8 through an elastic body 10. The elastic body 10 is provided within a quarter of the periphery of the support rod 8 that is located, when viewed along the axis of the shaft member 11, forward of the line of action of a radial shaft load on the shaft member 11 with respect to the di...

A semiconductor device has a memory cell, decoders, a redundancy circuit and a mode setting circuit. The memory cell array has word lines including a redundant word line, bit lines and memory cells. A row decoder selects the word lines in response to a row address. Further, the row address decoder selects the redundant word line when a replacement signal is received. A column decoder selects the bit lines in response to a column address. A row address redundancy circuit stores a redundant row ad...

A memory test circuit receives test pattern data from a processing unit having a first data width, expands the test pattern to a second data width greater than the first data width, and writes the expanded test pattern data into a memory having the second data width, thereby avoiding the need for extra write cycles when a processing unit tests a memory having a greater data width. The test pattern data may be expanded by, for example, copying a specific bit to multiple bit positions, inverting a...

A plate body includes: an inner bulge protruded on one side of the panel body and recessed on the other side and has a periphery spaced from attachment parts; connector bulges having a certain width protruded on the one side of the plate body and recessed on the other side and connect the periphery of the inner bulge to the attachment parts; and an outer bulge recessed on the one side of the plate body and protruded on the other side and continuous with the inner bulge, the connector bulges and ...

A gas powered toy gun comprises a gas supplying portion from which a gas leading passage extends, a valve for controlling the gas leading passage to be open and closed selectively, a slider provided to be movable to a barrel portion connected with a bullet holding chamber and provided with a pressure receiving portion for moving backward in order to supply the bullet holding chamber with a sham bullet, a movable member having an inner space formed therein and provided to be movable in the slider...
