摘要:
A duty ratio for controlling an engagement force of a friction engagement device on the side of upshift engagement is corrected by an amount corresponding to an intermediate correction control value in the course of the shift. In addition, on a prerequisite condition that learning correction of a constant standby pressure control value at the start of the shift is converged, learning correction is performed for the intermediate correction control value according to a gradient of a turbine speed. Thus, a shift shock is prevented from occurring due to abrupt engagement of the friction engagement device and the like at the completion of the shift.

Provided is an electricity collection and distribution ring excellent in durability and the easiness of manufacturing while the size thereof is reduced, and also provided is a method for manufacturing the electricity collection and distribution ring. The electricity collection and distribution ring (2) comprises: first to fourth bus rings (21 to 24) for collecting electricity from and distributing electricity to each of the phase coils (111, 112, 113) of a three-phase motor (1); a plurality of fixing members (3) disposed at a plurality of predetermined positions in a circumferential direction of the first to fourth bus rings (21 to 24) and mutually fixing the first to fourth bus rings (21 to 24); and a plurality of connection terminals (4) for connecting the first to fourth bus rings (21 to 24) and the lead-out lines of the respective phase coils (111, 112, 113). The fixing members (3) integrally have a locking portion (30) for, among the first to fourth bus rings (21 to 24), locking the first bus ring (21) positioned at an end in an axis direction and a fixing portion (31) for mutually fixing the other second to fourth bus rings (22 to 24) by molding.
摘要:
A power transmission system for a vehicle is provided, including: a housing that can reserve oil therein; and a rotational member rotatably supported within the housing, with a surface of the rotational member being partly contactable with a surface of the oil reserved in the housing, in which the surface of the rotational member partly contactable with the oil surface includes a non-contact surface that is not in contact with any power transmission members, the non-contact surface having an oil repellent section. When the surface of the rotational member contacts the oil surface, the oil repellent section repels the oil quickly. Therefore, the amount of oil, which adheres to and rotates with the rotational member agitating the oil, decreases. This reduces oil heat generation and rotational resistance to the rotational member.

In an apparatus for generating and managing production processing structure in a production management system of a factory, the structure of factory made up of the names or other identifiers of process points obtained by subdividing the factory production line is hierarchically registered in the storage device of the management computer (server; S200), the terminal computers and devices used in production are registered as terminal devices (S202), and tasks (from among tasks generated in advance and stored in the disk of the management computer) for achieving the operation or processing to be implemented at the process points are selected for each process point and registered in the order of execution (S204), while linking the terminal devices with definition information that correlates them, once the terminal computers are activated, the registered tasks are executed by the management computer (server) based on the definition information thus registered, so that the production record information is accumulated, production instructions are distributed to the devices based on the accumulated production record information, such that the product is produced. With this, the number of man-hours and the costs of developing the production management system in building a factory can be significantly reduced, and the turnaround time can be shortened.

摘要:
A front lens group 1 and a rear lens group 2 having a diameter of about 5 mm held inside a cylindrical body 5 are capable of movement in the forward and backward directions via a front group movable body 3 and a rear group movable body 4, respectively. An image taking element such as a CCD is arranged at a prescribed position behind the cylindrical body. By setting the distance from each lens group to the CCD and the distance between both lens groups, an image is formed at a prescribed zoom on the CCD. From the 1× base state when the zoom magnification is made α×→β×→γ×, the positional relationship between the front lens group and the rear lens group becomes as shown in FIG. 1(b)˜(d). The two kinds of zoom magnification 1× and β× can be switched by fixing the front lens group and moving only the rear lens group back and forth between positions.
