摘要： On a semiconductor substrate with an active layer, a first-stage recess groove is formed by photolithography and wet or dry etching. On the semiconductor substrate and the surface of the first-stage recess groove, a surface passivation film a crystalline material such as i-GaAs or an insulating film of, e.g., SiON, is formed. The surface passivation film on an area where an ohmic electrodes is to be formed is removed and the ohmic electrode is formed on the area by vapor deposition. Thereafter, in the first-stage recess groove, a second-stage recess groove is formed by photolithography and wet or dry etching. A gate electrode is formed on the second-stage recess groove by sputtering or the like.

There is provided an axle 101 and a wheel body rotatable with respect to the axle 101. An automatic air supply mechanism 1 is provided on the wheel body. The automatic air supply mechanism 1 has a constant pressure maintaining section 2 and a compression section 3. The constant pressure maintaining section 2 is configured to maintain the air pressure therein at a constant value and connected to the pneumatic tire mounted on the wheel body 110 in air flow communication. The compression section 3 compresses air when the wheel body 110 is rotated with respect to the axle 101 and feeds the compressed air into the constant pressure maintaining section 2.

摘要： A memory core of a semiconductor data storing circuit device in a semiconductor chip is composed of a memory cell array having memory cells of rows and columns, data input/output circuits of a normal operation in which a data input line and a data output line for one bit of data are arranged at every four columns of the memory cell array, and checking circuits of a test operation in which a test data input line and a test data output line for one bit of test data are arranged at every eight (or two) columns of the memory cell array. In cases where the test data input/output lines for one bit of test data are arranged at every eight columns, because the number of test data input/output lines is lower than the number of data input/output lines, the number of input/output pins for the test operation can be reduced. Also, in cases where the test data input/output lines for one bit of test data are arranged at every two columns, because the number of test data input/output lines is higher than the number of data input/output lines, the number of memory cells simultaneously checked is increased, and a test operation time in the manufacturing of the memory cell array can be shortened.

摘要： In a stepping motor, stator yokes have a plurality of comb-tooth-shaped magnetic poles 5b, 6b, 7b and 8b in such a manner that the comb-tooth-shaped magnetic poles are opposed to each other coaxially to a rotor portion made from a permanent magnet magnetized to have multiple magnetic poles, and an excitation coil is fitted on the external circumference of the stator yokes and the excitation coil and the stator yokes are surrounded by a frame yoke. Each of the yokes is formed of an Fe—Cr alloy having a predetermined ferrite single-phase structure so that occurrence of eddy currents in an alternating-current magnetic field is suppressed.
