摘要:
A speed change device for shifting the gear of a transmission by using a cylindrical drum that reciprocally moves and rotates, featuring the structure of a compact size and excellent operability. To execute the shifting operation, the speed change device of the invention uses a cylindrical drum 4 that reciprocally moves in the axial direction and is rotatably supported. Fork pins FP1 to FP4 coupled to a plurality of forks of the transmission are fitted into drum grooves 41 to 44 formed in the cylindrical surface of the cylindrical drum. In each drum groove, there are formed small width portions of a width nearly equal to that of the fork pin and large width portions wider than the small width portions in a manner that the fork pin positioned at the small width portion is shifted. To shift the gear, the cylindrical drum 4 is rotated by a select motor 6 to select the fork pin positioned at the small width portion. Next, a threaded shaft 1 is rotated by a shift motor 7 to move the cylindrical drum 4 in the axial direction to thereby shift the selected fork pin.

A dual clutch transmission having two input shafts respectively connected to clutches, and an intermediate shaft, preventing the intermediate shaft from rotating idle when the vehicle is traveling at high speeds and avoiding excess stirring of lubricating oil in the transmission and increase in noise. In the dual clutch transmission, a direct connection clutch C3 is provided between one input shaft S2 and an output shaft S4, and an intermediate shaft connection clutch C4 for interrupting the transmission of power is provided between the intermediate shaft S3 and the output shaft S4. When the power is directly transmitted from the input shaft S2 to the output shaft S4 via the direct connection clutch C3, the intermediate shaft connection clutch C4 is disconnected to stop the rotation of the intermediate shaft S3 and to prevent the lubricating oil from being excessively stirred by the idle rotation of the intermediate shaft S3. Further, the intermediate shaft connection clutch C4 is disconnected, and a transmission step is constituted by utilizing the gear trains among the two input shafts and the intermediate shaft S3, making it possible to omit one gear train and, therefore, to shorten the length of the transmission.

There is disclosed a silver halide photographic light-sensitive material which contains, on a support, a specific nitrogen-containing heterocyclic compound, and a divalent metal cation that is an acid with intermediate hardness/softness classified in accordance with the HSAB principle, in an amount 1 to 300 times the number of moles of the nitrogen-containing heterocyclic compound. The light-sensitive material can form an image with high sensitivity and low fogging, both in heat-development processing characterized by its ease and rapidness, and in usual liquid-developing processing that is widely used.

摘要:
A Bloch line memory device and a method of erasing information in which, for erasure of a Bloch line pair representative of one bit of information and located in one end portion of one stripe domain, the stripe domain is stretched by decreasing the intensity of a bias magnetic field, an erasure Bloch line pair having a rotation of magnetization opposite to that of the to-be-erased Bloch line pair is injected into the end portion of the stretched stripe domain by supplying a current pulse signal to a conductor arranged substantially perpendicualr to the lengthwise direction of the stripe domain, and the stretched stripe domain is shrinked by restoring the intensity of the bias magnetic field, so that the to-be-erased Bloch line pair is combined with the erasure Bloch line pair to cancel the former.
