A trench excavator capable of excavating a trench of a rectangular section suitable for formation of an underground diaphragm wall. The underground diaphragm walls are now applied as underground structures replacing caissons, rigid foundations for multistory or tower like buildings, underground tanks and the like. In the trench excavator according to the invention, a pair of drum cutters and a ring cutter interposed therebetween form one unit and a plurality of such units are arranged parallel to one another, whereby an unexcavated portion produced between the drum cutters can be cut out by the ring cutter, leaving no unexcavated portion.

In the disproportionation reaction of a linear olefin such as 1-butene cocted in the presence of a supported tungsten oxide catalyst such as a tungsten oxide-silica catalyst, isomerization of the olefin is inhibited and the conversion ratio for the disproportionation reaction of the olefin is increased by conducting the reaction in the presence of an amine compound such as ammonia or n-butylamine or a halogen compound such as chloroform.

A gate array LSI having functional blocks formed by interconnecting a plurality of basic cells arranged on a semiconductor substrate in matrix form and either signal conductive patterns or first power conductive patterns. According to the gate array LSI, the first power conductive patterns are disposed on the plurality of basic cells arranged in line and are divided and disposed on the basic cells so as to interpose the signal conductive pattern therebetween. It is therefore possible to improve the efficiency of wiring macrocells.

A multiple-power IC device comprising an input buffer circuit for receiving an input signal and a plurality of power voltages of different magnitudes. The input buffer circuit has an output associated with each of the plurality of power voltages for outputting the input signal in accordance with a predetermined threshold voltage. The device further comprises an internal circuit, a switching circuit interposed between the input buffer circuit and the internal circuit, and a power voltage determination circuit coupled to the switching circuit and receiving the plurality of power voltages. The power voltage determination circuit controls the switching circuit to selectively couple an output of the input buffer circuit to the internal circuit in accordance with the magnitude of the received power voltage. Thus, the input signal is coupled to the internal circuit according to the predetermined threshold voltage regardless of the power voltage applied to the input buffer circuit.

A clock supply circuit having a circuit area includes an input terminal for receiving a clock pulse and a buffer having an input electrically connected to the input terminal and an output. The buffer is disposed in the center of the circuit area. The clock supply circuit also includes a main conductive pattern electrically connected to the output of the buffer. The main conductive pattern is disposed through the center of the circuit area. Each of the branch conductive patterns is electrically connected to the main conductive pattern and extends from the main conductive pattern. Also, each of the branch conductive patterns has a width smaller than the width of the main conductive pattern. Each of the clock receiving circuits is electrically connected to one of the branch conductive patterns and disposed in the circuit area. The number of the clock receiving circuits electrically connected to one branch conductive pattern is same.
