摘要:
An address signal line having a stub structure connects between at least three memory elements and a data transferring element and transmits address signals for the memory elements. An address terminal of the data transferring element has an impedance lower than a characteristic impedance of the address signal line. A wiring length TL0 from the data transferring element to a first branch point S1 where a branch line is branched at a shortest distance from the data transferring element is configured to become equal to or greater than a wiring length TL1 from the first branch point S1 to a second branch point S2 where a second branch line is branched. A wiring length TL3 from the second branch point S2 to a third branch point S3 where a third branch line is branched is configured to become greater than the wiring lengths TL0 and TL1.

A method of manufacturing a semiconductor device includes, but is not limited to, the following processes. A seed layer is formed over a substrate. The seed layer includes first, second, and third portions. A first electrode covering the first portion of the seed layer is formed without forming an electrode on the second and third portions of the seed layer. The third portion of the seed layer is removed so that the first and second portions remain over the substrate, and the first and second portions are separated from each other.

An earphone is disclosed. The earphone comprises an external auditory meatus insertion member, a casing and a driver unit. At least a part of the external auditory meatus insertion member is insertable into an external auditory meatus. The external auditory meatus insertion member is attached to the casing. The driver unit is disposed within the casing to generate sounds. The casing includes a front space formed in front of the driver unit, a sound guide hole in communication with the front end of the front space to cause sounds to impinge on the external auditory meatus, and a rear space formed in the rear of the driver unit.

According to a steering control method, before starting, a pattern steering angle table on which pattern steering angles for the front and rear wheels at respective change points of the track are listed is prepared in view of a track condition, etc. from a departure point to a destination point, a vehicle is steered in accordance with a pattern steering angle read from the table, a track widthwise position of the vehicle on running is detected so as to calculate correcting steering angles by which the track widthwise position of the vehicle coincides with a desired position, and the correcting steering angles are added to pattern steering angles so as to obtain desired steering angles by which the front wheels are steered. The pattern steering angle, the corrected steering angle and the desired steering angle are calculated for each of the front and rear wheels, independent from each other.
