Abstract: A main body holder has a base wall with a through-hole, a holding portion, and a pivotally attached clip piece. A stopper member is movably disposed within the base wall through-hole for movement between a restricting position and a releasing position. In the restricting position, the stopper member projects from the base wall and is configured to engage and securely hold the main body of a portable apparatus on the holding portion so that the apparatus main body is only partially disposed over the base wall through-hole in a state in which the apparatus main body is fully received by the holding portion. In the releasing position, the stopper member extends into the through-hole and does not project from the base wall so that the apparatus main body is allowed to be slid relative to the holding portion. An urging member urges the clip piece into contact with the holding portion and urges the stopper member to the restricting position.

A color code and a line code are added to each of the data. Image data having the same color code and the same line code are combined. According to the image reading apparatus structured as described above, it is possible to obtain data capable of reproducing read data for each color on the same line without errors.
Abstract: In a method of manufacturing a high withstanding voltage MOSFET, a region to be doped with impurities and a region to be doped with no impurity are provided when ion implantation of the impurities is performed in the channel forming region, for controlling a threshold voltage. The region to be doped with no impurity is suitably patterned so that impurity concentration of the channel forming region near boundaries between a well region and a source region and between the well region and a drain region having the same conductivity type as the well region may be increased, to thereby induce a reverse short channel effect. By canceling a short channel effect with the reverse short channel effect induced by the above-mentioned method, the short channel effect of the high withstanding voltage MOSFET may be suppressed.

The inner races or the outer races of the rolling bearings at both axial ends, which are brought into contact with the inner races or the outer races of adjacent rolling bearings, are fixed to the sleeve, and the outer races of the central two rolling bearings form a radial gap between confronting surfaces of the sleeve and the outer races or between confronting surfaces of the shaft and the inner surfaces.
Abstract: To release a medium securely from a fixed roll without damaging the medium. A releasing roller is disposed between a roll and a transport roller for nipping a medium and transporting the medium to a printing position. The releasing roller is rotated by a releasing motor so as to release the medium from the roll in a tangential direction of the roll. In addition, a sag part obtained by sagging the medium is formed between the releasing roller and the transport roller. A tension roller is placed on the sag part so that a constant tension is exerted on the released medium. A sag amount of the sag part is detected by monitoring a lower end part of the sag part with a sensor utilizing infrared rays. A printing apparatus releases the medium by the releasing roller to supply the medium so that the sag amount is within a predetermined range. The medium on which the constant tension is exerted is delivered by the transport roller onto a platen and is printed by a head.
Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.
