The work rolls of two sets of roller groups are held within one-piece metal chock in a rolling mill. A one-piece metal chock in which the driving side and operating side are separate then provides support at the upper part of the rolling material, with support similarly being provided at the lower part using another pair of single piece metal chocks. Two sets of roll groups can then be arranged close to each other, strip walking and strip curving can be prevented, and a rolling mill, rolling method and rolling installation that are easy to maintain and provide superior rolling efficiency can be provided.

An electrically erasable semiconductor nonvolatile memory device has an array of memory cells arranged in rows and columns and one or more information erasure signal generating circuits. Each of the memory cells of the memory cell array includes a field-effect transistor element having a control gate connected with a word line conductor extending in a direction of the rows, a floating gate where carriers may be accumulated, a drain connected with a data line conductor extending in the direction of the columns and a source connected with a source conductor. The memory cell array may be divided into a plurality of memory blocks so as to have boundaries in the row direction or in the column direction, with the source conductors arranged in the row direction or in the column direction. Information erasure signals may be supplied to the source conductors or data line conductors with a time delay therebetween.

A portable radio device helical antenna 1 is fabricated by a method wherein the cutting boss component 6 of a molded element 7, that has a spirally cut groove 4 formed around an insulator and that has a mounting component 3 at one end and the boss component 6 at the other end, is chucked, the components are metal plated, the metal layer is then removed except from the groove 4 and mounting component 3, the boss component 6 is then cut off and that location is machined, and a radio device base plate fixing hole 9 is formed in the mounting component 3. The mounting component 3 is then mounted on the base plate of a radio device main body.

A novel gate circuit is disclosed. A first semiconductor switch includes a couple of main terminals connected between a first potential level and an output node, in which a high impedance state is held in response to an input signal having a first logic level and a second logic level, and the impedance state changes from high to low only during a transient period when the input signal changes substantially from the first to second logic level. A second semiconductor switch includes a couple of main terminals inserted between a second potential level different from the first potential level and the output node, in which a high impedance state is held in response to the input signal, and the impedance state changes from high to low only during a transient period when the input signal changes from the second to first logic level.

In a thin film device having a hydrogenated amorphous silicon film, a metal layer is formed on the hydrogenated amorphous silicon film and then the metal layer is removed. A resulting reaction layer formed on the hydrogenated amorphous silicon film is used as a resistor.
