  • Publication number: 20150159037
    Abstract: A coating composition is provided comprising a hydrophilic characteristic-effecting material compound. The production of the hydrophilic characteristic-effecting material compound is effected by admixing of operative starting materials. The operative starting materials include a superwetter material and an adhesion promoting agent material. The hydrophilic characteristic-effecting material compound includes a superwetter material-derived coating composition material fraction and an adhesion promoting agent material-derived material fraction. The adhesion promoting agent material-derived coating composition material fraction is configured for interacting with a substrate such that, in response to, at least, contacting between the coating composition and the substrate, adhesion of an operative surface material to the substrate is effected.

  • Publication number: 20140379805
    Abstract: A method for cross-platform synchronization of contacts in a multi-platform environment is disclosed. The method includes: acquiring a contact to be associated with an account in a social platform; acquiring an account of a friend associated with the contact in the social platform, and binding a phone number of the contact with the associated account of the friend in the social platform; and uploading the phone number and the account in the social platform bound together to a server. When it needs to view social information of a contact, the above method can simplify user operation, reduce time spent for operation in the mobile terminal and increase the battery life of the mobile terminal. Furthermore, a device for cross-platform synchronization of contacts in a multi-platform environment is also disclosed.

  • Publication number: 20140149472
    Abstract: Examples of the present disclosure may provide a method, device and storage medium for clearing up a file system. A volume may be opened and locked according to a clearing-up instruction. The clearing-up instruction may indicate the volume which is to be cleared up. Garbage information on a disk corresponding to the volume may be cleared up. The volume may be unlocked after the garbage information is cleared up. The device may include a locking module, a clearing-up module and an unlocking module. With the example of the present disclosure, when the clearing-up instruction is received, the garbage information on the disk corresponding to the volume may be cleared up. Therefore, the privacy of the user remained in the file system may be thoroughly cleared up, the leakage of the privacy of the user may be avoided and the security of the file system may be enhanced.

  • Patent number: 7278593
    Abstract: A common rail fuel injector comprises a three-way control valve that controls the flow of high-pressure fuel to a fuel cavity for fuel injection. Specifically, when the control valve is transitioning to a first, on position, from a second, off position, high-pressure fuel is provided to both the fuel cavity and to a check control cavity, thereby preventing fuel injection until the control valve seats in the first, on position. Once seated in the first, on position, the control valve only provides high-pressure fuel to the fuel cavity allowing fuel injection to occur. To stop injection, the control valve is moved from the first, on position to the second, closed position. Once again, while the control valve is in the transition location between the two positions, high-pressure fuel is provided to both the fuel cavity and to the check control cavity thereby terminating injection.

  • Patent number: 7021565
    Abstract: Common rail fuel injectors typically have difficulty in changing an injection rate during an injection event. Fuel injectors for this common rail fuel injection system include a multi-position admission valve. The admission valve is stoppable at a middle position to inject fuel at a low rate. The lower rate is accomplished by leaking some fuel to drain to reduce injection pressure. The admission valve is also stoppable at a fully open position to inject fuel at a high rate. Fuel injection events are ended, and the fuel injectors maintained between injection events, with the admission valve member in contact with a supply seat to close the high pressure supply passage. This strategy can be used in conjunction with a spring-biased needle valve member to expand fuel injector capabilities.

  • Publication number: 20040046056
    Abstract: A fuel injector in an engine includes a spring cavity, a piston, a plunger, a spring, a fuel cavity, and a stop plate. The piston is hydraulically controlled to force the plunger down to compress fuel in the fuel cavity. However, under certain conditions, the plunger can contact the stop plate and/or the spring can become overcompressed. Both of these conditions can cause damage to the fuel injector. The present invention locates a pressure equalization channel in such a way as to dampen the motion of the piston to prevent this damage to the fuel injector.
