41results about How to "Increase the amount of overlap" patented technology

First and second separable portions such as opposite ends of a strap that is wrapped around one or more articles to be secured are overlapped. A ratchet is operable with the portions joined in overlapping relation for increasing the amount of the overlap, thereby effectively shortening the strap and taking up slack. A mechanical advantage is provided that makes it easy to tighten the strap securely around one or more articles. A lock can be locked to prevent, or unlocked to enable, separation of the portions.

A controller restricts an operation amount of the variable valve actuation mechanism of a fluid pressure operated type such that increase in the valve overlap amount of an engine is restrained when the engine is in a transient operation state in which the output of the engine increases. When the controller determines that the variable valve actuation mechanism is in the locked state, the controller relaxes the restriction imposed on the operation amount of the variable valve actuation mechanism. Hence, a decrease in follow-up performance of valve properties to desired properties is restrained while restraining temporary stagnation of increase in engine rotational speed caused by vehicle acceleration.

The invention relates to a cable oscillatory wave partial discharge detection system shielding device which comprises a shielding box provided with an amplifier, a collecting card, detection impedance, a switch power and a low pass filter inside. The shielding box is made of a steel plate with the thickness of 2 mm and capable of preventing components inside the shielding box from being interfered by outer electromagnetic waves. The low pass filter is an electro-magnetic interference (EMI) difference module bipolar filter. Due to the fact that all the components of the system are grounded to one point of the shielding box body, coupled circuits of common impedance can be reduced and internal interference electromagnetic wave can be reduced. During the process of wiring, the power line and the signal line are unparallel and controlled with 10 centimeters, capacitance of the coupled circuits is effectively reduced, high frequency interference signal paths can be avoided, and the interference electromagnetic waves can be further reduced.
