Abstract: The present invention relates to a method for controlling an air conditioning outlet of a vehicle, including: collecting an ambient temperature and a user set temperature; determining a target value according to the ambient temperature and the user set temperature; determining a target working mode from a plurality of preset working modes of an air conditioning outlet according to the target value, the working mode including a preset air outlet direction; and enabling the air conditioning outlet to work in the target working mode.

Abstract: A universal joint which retains a lubricant, is capable of suppressing the exudation of a lubricating component to a minimum amount and preventing the lubricant from scattering from an open portion when the lubricant is deformed by an external force, and a method for producing the universal joint. In the universal joint, a rotational torque is transmitted by engagement between a torque transmission member (6) and tracks (4, 5) provided on an outer member (2) and an inner member (3); the torque transmission member (6) rolls along the tracks (4, 5), thus moving in an axial direction; and a porous solid lubricant (10) is enclosed on a periphery of the torque transmission member (6). The porous solid lubricant (10) containing a lubricating component and a resin component is a solid made porous by foaming and hardening the resin component.

Abstract: The present invention provides a universal joint which is excellent in the performance of retaining a lubricant, is capable of suppressing an exudation amount of a lubricating component to a necessary minimum amount and preventing the lubricant from scattering from an open portion when the lubricant is deformed by an external force, has a long life, costs low, and is excellent in the productivity thereof; and a method for producing the universal joint. In the universal joint, a rotational torque is transmitted by engagement between a torque transmission member (6) and tracks (4, 5) provided on an outer member (2) and an inner member (3); the torque transmission member (6) rolls along the tracks (4, 5), thus moving in an axial direction; and a porous solid lubricant (10) is enclosed on a periphery of the torque transmission member (6).
