Inventor: MURAOKA TSUTOMU
IPC: B62J11/00
Filed: 2000-02-23
Abstract: PROBLEM TO BE SOLVED: To easily install a bracket assembly on a spoke, and prevent rotation or a lengthwise directional movement along a shaft of the spoke by extending a claw part in a spoke receiving recess from a housing surface, and fixing the flat spoke in the spoke receiving recess by snap engagement. SOLUTION: When inserting a flat part of a spoke 19 into a spoke receiving recess 39 in the first place, a housing 32 is rotated around the axis of the flat spoke 19, and a circular end part is engaged with a circular end part of the spoke 19. Engagement of a surface functions so as to engage the spoke 19 in the spoke receiving recess in a snap in cooperation with a holding surface of a claw part 48. An inner holding surface engages with the flat part of the spoke 19 so as to hold the spoke 19 toward a bottom wall of the spoke receiving recess 39 by low pressing force. Thus, the housing 32 is elastically held by the spoke 19 to prevent a lengthwise directional movement of a magnetic device along a lengthwise shaft of the spoke 19.

Filed: 2000-02-24
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of appropriately preventing a situation that developer put between an image carrier and a developer carrier is aggregated to deteriorate image quality. SOLUTION: In this image forming device 1, a toner image is formed and developed on the surface of a photoreceptor 2 by supplying toner to the photoreceptor 2 by the developing roller 5 of a developing part 3.

By pressing the roller 5 toward the photoreceptor 2 by an elastic member such as a spring, the roller 5 uniformly abuts on the photoreceptor 2 in the shaft direction of the roller 5. The roller 5 is formed in the shape of a cylinder obtained by sticking rubber material to the periphery of a core bar, provided with a surface layer whose surface is properly roughed and coated with coating material and an inner layer lower than the surface layer, and set so that the hardness of the surface layer may be higher than that of the inner layer.  Therefore, the roller 5 uniformly abuts on the photoreceptor 2 and developing nip width is made small, so that a uniform and excellent-contrast image is formed.

IPC: H04L9/26
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To realize illegal access prevention by means of the collation of a cryptographic key by allocating a cryptographic key group to each magnetic card though the magnetic card is an open electronic storage, information contents do not have to be worried to be read by making the contents into a cryptographic code and recording it, many illegal copies are not used and this technique needs the illegal access prevention. SOLUTION: Components constituting a chaos block cryptograph are a cryptographic table, a decoding table and a cryptographic key. The cryptographic table and the decoding table are composed of only restricted codes that are allowed in communication by a card reader/writer. The cryptographic key is the allocation of a block code to the degenerated quantum of the tables. The cryptographic key can inherently be issued from an initial value as permutation, and a cryptographic key group inherent in the initial value is allocated to each magnetic card. It is possible to prevent a copy from being illegally used by the collation of the cryptographic key because cryptographic key groups with each other do not share the same permutation.

Title: Method for determining vehicle rollover
Inventor: MOMOHARA SHIGERO
IPC: B60R21/16
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To detect at early stages the possibility of a 'trip-over' type rollover which occurs upon collision of tires against curbstones or the like, in determining whether or not there is a possibility of vehicle rollover according to the roll angle and roll angular velocity of the vehicle. SOLUTION: A threshold line S is set on a two-dimensional map whose parameters are the roll angle θ and roll angular velocity ω of the vehicle; when hysteresis lines of the actual roll angle θ and roll angular velocity ω of the vehicle cross the threshold line S from a non-rollover area on the side of an original point to a rollover area on the side opposite to the original point, one determines that there is a possibility of vehicle rollover.  If the vehicle slips sideways with its tires colliding against curbstones or the like, the differential value dω/dθ (or time differential value dω/dt of ω) of the roll angular velocity ω with respect to the roll angle θincreases abruptly (refer to A portion in Figure 9); upon detection of this event the threshold line S on the map is moved in the direction to approach the original point, to thereby make it possible to determine at early stages that there is a possibility of vehicle rollover.
