In a server for authenticating a user, an acquiring unit acquires current authentication information that is created using an arbitrary value and that is used for a current authentication process, from user. A receiving unit receives first transmission information in which next authentication information to be used for a next authentication process is hidden using the current authentication information, and second transmission information in which the arbitrary value is hidden using the next authentication information, from the user. A calculating unit calculates the next authentication information based on the first transmission information and the current authentication information, and the arbitrary value based on calculated next authentication information and the second transmission information. A determining unit determines whether to authenticate the user based on the arbitrary value and the current authentication information.

An image forming apparatus has an image forming unit together with a fixing unit which uses two rotating members to form a nip in which the recording material with an unfixed image is fed. A driving unit drives the rotatable fixing members and a flywheel is used for increasing an inertial force of that drive, there also being a connecting device which selectively connects the flywheel with the driving unit together with a switching device that switches operation of that connecting device in accordance with the type of recording material being used or the density of the image to be printed.

A semiconductor device has an n channel conductivity type field effect transistor having a channel formation region formed in a first region on one main surface of a semiconductor substrate and a p channel conductivity type field effect transistor having a channel formation region formed in a second region on the main surface of the semiconductor substrate, which second region is different from the first region. An internal stress generated in the channel formation region of the n channel conductivity type field effect transistor is different from an internal stress generated in the channel formation region of the p channel conductivity type field effect transistor. The internal stress generated in the channel formation region of the n channel conductivity type field effect transistor is a tensile stress, while the internal stress generated in the channel formation region of the p channel conductivity type field effect transistor is a compressive stress.

A drive apparatus improves drive efficiency while reducing device size, and a lens unit and a camera using the drive apparatus. A cam member is driven rotationally by vibration of an oscillator in the lens unit and thereby causes lenses to move forward and backward. The construction and operation of the drive apparatus supplants the need for a complicated drive mechanism using an electromagnetic motor and incumbent gears or cam rings. The simplified drive apparatus enables the device in which it is embodied to be made compact. Driving the lenses by means of a cam member minimizes energy loss due to friction, and thus sufficiently improves drive efficiency.

A miniature zoom lens has, sequentially from an object side, a first lens group G1 having negative refractive power, a second lens group G2 having positive refractive power and including a diaphragm, and a third lens group G3 having positive refractive power. The first lens group G1 is formed from a single negative lens L1. The second lens group G2 is formed from, sequentially from the object side, a single positive lens L2 and a single negative lens L3. The third lens group G3 is formed form a single positive lens L4. The first lens group G1 is immovable and the second lens group G2 and the third lens group G3 move in an optical axis direction at variable power. The miniature zoom lens provides a large zoom ratio while keeping a constant total length.

A highly reliable monolithic ceramic capacitor which has no structural defect, e.g. peeling, and which is not susceptible to water from the outside and a method for manufacturing the same are provided. A lead portion of an internal electrode is configured to have a shape provided with a taper-shaped portion in which the width gradually decreases with increasing proximity to the end surface of a ceramic element, and the shape of the end portion opposite to the lead portion of the internal electrode is adjusted to be substantially rectangular. Regarding a pair of internal electrodes facing each other with the ceramic layer therebetween, the internal electrodes are laminated while the positions thereof are displaced with respect to each other in order that a corner portion in the substantially rectangular portion of one internal electrode are located in the vicinity of, but outside the taper-shaped portion of the other internal electrode.
