A method of producing a steel material includes a step of adding Ca to molten steel with an amount of Ca adjusted within a range satisfying the formula (1) below: where Ca is the amount [kg] of Ca added, y is an yield [%] of Ca, [S] is a concentration [% by mass] of S in the steel before addition of Ca, [AlO] is an amount [% by mass] of AlOin the steel before addition of Ca, and W is a weight [kg] of the molten steel.

In wire electrical discharge machining, to make it possible to determine the state of rough machining or finishing in various stages, the machining speed, the working voltage, and execution portion information are stored as a set for each movement of a fixed distance in the process of execution of a plurality of times of machining in which rough machining through finish machining are consecutively executed, and are displayed in a two-dimensional graph.

A method of patterning at least one object layer, includes a step of forming a mask on the object layer, and a step of selectively etching the object layer using the mask. The mask is made of a magnetic metallic compound with a basic metal of nickel or cobalt containing at least group 3B element and/or group 5B element.

An object of the invention is to improve the thermal conductivity and the hardness of a first shield gap film and a second shield gap film. Another object is to improve the thermal conductivity while decreasing the stress. The first shield gap film and the second shield gap film are formed of an insulating film which includes at least one of BN, SiN or CN as the main component, a little Ar and oxygen. Higher thermal conductivity can be obtained by using the insulating film which includes at least one of BN, SiN, or CN so that the heat generated in an MR element can be effectively dissipated. In addition, including Ar improves the hardness so that excessive polishing can be suppressed at the time of forming the air bearing surface. Moreover, including oxygen decreases the stress and exfoliation of the first and the second shield gap films can be avoided.

With this invention, the clock skew of logical integrated circuits is suppressed. To do this, with this invention, chip integrated circuit forming areas are divided into rectangular blocks with the same dimensions, clock drivers are placed in each block, and these clock drivers are connected with basic logic circuits and dummy loads. The total basic logic circuit count and dummy load count is made the same for all clock drivers. This allows the load of each clock driver to be made the same, so generation of clock skew can be suppressed.

Integrated circuit and the design method thereof

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.

Gate array LSI

A rectangular array of 6.times.150 bits is divided into 50 rectangular arrays of 8.times.3 bits with 2 check bits added, resulting in 50 codes C.sub.2. This encoding is executed 50 times to form a rectangular array of 8.times.150 bits and each of its rows is encoded into a code C.sub.1 of 166 bits with 16 check bits added. This encoding is executed eight times to form a codeword of a generalized product code, which includes 8.times.166 bits and each row following 12 synchronizing bits. Errors are detected in the codes C.sub.1 decoded from the codeword to produce erasure information which is utilized to correct the code C.sub.2. Then, the original array is reproduced.
