Title: Method of detecting wrinkle on sheet member
Inventor: PHINNEY DANIEL P
IPC: B65H7/06
Filed: 2001-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for detecting wrinkles on a sheet member. SOLUTION: This device and method allow a variation in the angle of a sheet member relative to a reference line to be detected. When the variation in the angle exceeds a threshold value, it can be detected that the sheet is wrinkled. In an exampled embodiment, an ultrasonic wave signal can be used for detecting wrinkles. When an ultrasonic wave passes through a sheet member, for example, paper, both a phase shift and a reduction in amplitude occur in the ultrasonic wave signal. When the sheet angle varies relative to the ultrasonic wave signal 16 due to the wrinkles on a sheet P, a phase shift and a variation in amplitude occur in the signal 17 passed through the sheet P. Accordingly, when the sheet is started to be wrinkled, the phase shift and the variation in amplitude occur in the signal. These changes can be used for detecting the start of paper jamming and wrinkles on the sheet member.

IPC: H03K19/0948
Filed: 2000-06-30
Abstract: A high bandwidth clock buffer, including a steering circuit, significantly increases the maximum frequency at which CMOS technology can be used to perform high-speed logic functions. In particular, the clock buffer includes a steering circuit for enhancing a voltage follower stage. The steering circuit includes steering transistors positioned between voltage follower transistors and constant current sources. The steering circuit switches all or substantially all of the current from both of the constant current sources through whichever of the two voltage follower transistors is being pulled low, thus doubling the amount of current that is available for slewing when the output is being pulled low. At the same time, since the voltage follower transistor that is being pulled high no longer has to source the constant current I0, the effective maximum current that can be supplied to charge up the load capacitance is increased by approximately I0. The clock buffer provides a higher unity gain bandwidth than a standard CML buffer, while maintaining a well controlled delay which will track other logic gates.

Abstract: A multi-cylinder internal combustion engine with at least one cylinder row is equipped with a cylinder head housing containing intake and exhaust valves that feed combustion air to the cylinders and release combustion exhaust gases through an exhaust system via control devices in dependence of the position of the crankshaft. Devices for generating differing exhaust valve lift progressions of at least two cylinders arranged in one cylinder row are incorporated to reduce overlapping opening phases of these exhaust valves. The intake valve and the exhaust valve of one of the two cylinders are themselves in an overlapping opening phase. Thereby, a uniform filling rate of the cylinders with new gas is achieved, particularly on a V-8 engine with a 90°-bent crankshaft.
