  • Publication number: 20140001690
    Abstract: A cylinder unit includes a cylinder, a rod guide, a piston, a piston rod, and a rebound member provided between the rod guide and the piston to absorb impact generated when the cylinder unit is fully extended. The rebound member includes a coil spring arranged around an outer circumference of the piston rod and a pair of upper and lower holder members fitted to the fixing portions formed in both ends of the coil spring so that the piston rod is inserted into a shaft center hole. The center portion formed between the fixing portions of the coil spring has a diameter smaller than that of the fixing portion.

  • Publication number: 20130320604
    Abstract: Provided is a viscous-fluid-enclosing damper which attenuates, by using viscous resistance of a vibration-damping composition, vibrations transmitted between a support and an object to be supported, the support and object being attached to a closed container enclosing the vibration-damping composition of a viscous fluid. The viscous-fluid-enclosing damper alters few vibration-damping properties even when used under high temperatures and/or conditions where the vibrations are repeatedly generated for a prolonged period. Also provided is the vibration-damping composition which is used for the viscous-fluid-enclosing damper. The viscous fluid contains a viscous liquid having dispersed therein at least one type of heat-resistant resin particles and a dripping inhibitor, the particles being selected from polyethylene and nylon having an average molecular weight of from 50×104 to 600×104 and an average particle size of from 10 ?m to 200 ?m and preferably from 10 ?m to 160 ?m.

  • Publication number: 20130033134
    Abstract: An electric tool may include a motor housing and a motor disposed within the motor housing. The motor has a stator fixed in position relative to the motor housing and a rotor rotatable about a motor axis. Cooling air can flow within the motor housing across the motor in a direction substantially parallel to the motor axis. A baffle may be disposed within the motor housing for regulating the flow of cooling air across the motor. At least a part of the baffle may be positioned within a range of a length of the stator with respect to the axial direction of the motor axis.

  • Patent number: 7447521
    Abstract: A microprocessor used in a pair with a baseband processor for performing the baseband processing, is provided with a central processing unit for calculation processing, a counter capable of measuring time in the calculation processing by the central processing unit, and an interface which enables the baseband processor to read the counter. By making the baseband processor read the counter, the processing by the baseband processor is synchronized with the processing by the central processing unit in the microprocessor. Consequently, it is possible to establish synchronization between video and voice when the video processing and the voice processing are separately performed by different processors.

  • Patent number: 7275090
    Abstract: An information processing apparatus, such as might be associated with an in-home audio or video control device or a home appliance operated by a user, is provided with input allowing the user to set accuracy of a log of device operation history and/or to set a ratio of disclosure of the log information. A log accumulation control device efficiently collects the log information and offers users diversified levels of accuracy for the log information. In a further configuration, user-designated information acquired form user operation of the device identifies frequency of viewing and listening to each program, and reproduction of contents is controlled as a function of the user-designated information, e.g. to select among common contents and contents of different classification types.
