A stator iron core of an electric motor including plural magnetic pole segments. Each of the pole segments include a back yoke portion, a teeth portion projected from the back yoke portion, a connection portion provided to the back yoke portion for connecting adjacent magnetic pole segments, and a stepped-shaped notch on an outer circumference of the back yoke portion. Further, the stator iron core is circularly formed by bending the connection portions of the plural magnetic pole segments.

In an FDD control apparatus for controlling a floppy disk drive for driving a floppy disk loaded in the floppy disk drive, an FDD control part including a floppy disk controller (FDC) is disposed in an FDD side in lieu of a host side (a SET side). The host side (SET side) is loaded with a USB connector connected to the FDD control part. The FDD control part includes a flash ROM for storing a program for adjusting a step timing of a stepping motor.

Disclosed is a projection exposure method for transferring a pattern formed on a mask onto a photosensitive substrate through a projection optical system. A light beam having a first wavelength for exposure is radiated through the projection optical system onto a first mark area including a fiducial mark on a fiducial plate installed on a substrate stage, reflected light from the first mark area is detected to obtain a position of the fiducial mark. A light beam having a second wavelength to which the photosensitive substrate is not photosensitive is radiated through the projection optical system onto the first mark area, reflected light from the first mark area is detected to obtain a position of the fiducial mark. A positional discrepancy of the fiducial mark caused by the difference in wavelength between the first and second wavelengths is previously calculated on the basis of results of the detection. The light beam having the second wavelength is radiated through the projection optical system onto an alignment mark on the photosensitive substrate, reflected light therefrom is detected to obtain a position of the photosensitive substrate under the light beam having the second wavelength. A positional discrepancy of the photosensitive substrate is corrected on the basis of a result of the detection and the calculation, and thus positional alignment for the photosensitive substrate is performed, followed by actual exposure.

A pneumatic tire having a tread reinforcement layer constituted by a steel cord strip layer adjacent the carcass and an aromatic polyamide cord strip layer superposed to the steel cord strip layer in a parallel side-by-side relationship. The aromatic polyamide cord strip layer is folded at its both edges toward the center, in such a manner that the folded portions contact the main portion in a parallel side-by-side relationship. The main portion has a width ranging between 100 and 110% of the width of the tread surface, while the width of each folded portion ranges between 27.5 and 35% of the width of main portion. Furthermore, the free edge of each folded portion is located at a distance from the center of the outermost circumferential groove in the tread surface, which distance being between 25 and 75% of the distance between the outermost groove and the adjacent groove.

A liquid discharge head includes nozzles, a channel plate, a diaphragm member, a supporting substrate, a common liquid chamber forming substrate, a common liquid chamber, a groove, and a fluid restrictor. The supporting substrate is disposed at a side opposite the channel plate, with the diaphragm member interposed in between. The common liquid chamber forming substrate is disposed at a side opposite the diaphragm member, with the supporting substrate interposed in between. The common liquid chamber is communicated with individual liquid chambers. The groove is formed in an in-plane direction of a bonded face of the supporting substrate bonded to the diaphragm member. The fluid restrictor is disposed between the common liquid chamber and the individual liquid chambers. The fluid restrictor is formed between the groove of the supporting substrate and a bonded face of the diaphragm member bonded to the supporting substrate.
