Title: Belt for a continuously variable transmission
Inventor: FUJII TOORU
IPC: F16G5/16
Filed: 1998-10-12
Granted: 2000-06-01
Abstract: A belt for a continuously variable transmission in which an aggregate of metal rings formed by laminating a plurality of pieces of endless metal rings support a plurality of metal blocks. When the ratio xi of the coefficient of friction is set to be 2.0>xi>0.65, the amount of change in the tension on the metal ring of the innermost position decreases correspondingly. In particular, when the ratio xi of the coefficient of friction is set to be 1.0, resulting in the coefficient of friction <mu>ss between a ring and a ring, the amount of change in the tension on all metal rings become uniform, and each metal ring shares an amount of change in the tension which is 8% of the entire amount. This makes it possible to decrease the amount of change in the tension on the metal ring of the innermost position and, hence, to increase the durability of the aggregate of metal rings as a whole.

Abstract: Methods, systems, and apparatuses for down-converting an electromagnetic (EM) signal by aliasing the EM signal are described herein. Briefly stated, such methods, systems, and apparatuses operate by receiving an EM signal and an aliasing signal having an aliasing rate. The EM signal is aliased according to the aliasing signal to down-convert the EM signal. The term aliasing, as used herein, refers to both down-converting an EM signal by under-sampling the EM signal at an aliasing rate, and down-converting an EM signal by transferring energy from the EM signal at the aliasing rate. In an embodiment, the EM signal is down-converted to a demodulated baseband information signal. In another embodiment, the EM signal is a frequency modulated (FM) signal, which is down-converted to a non-FM signal, such as a phase modulated (PM) signal or an amplitude modulated (AM) signal.

The device is arranged such that: in the contact closed state, an electrical path is defined through which currents flow in substantial opposition to the first and second contact members and in opposite direction to each other, and the one end portions having contacts of the first and second contact members are positioned within the cylindrical space defined by the cylindrical insulator. Also, in the contact opened state, the contacts of at least one of the contact members are positioned outside of the cylindrical space defined by the cylindrical insulator. In addition, the current limiting device may comprise movable arms 3, 4 having movable contacts and a stationary member 5 having a stationary contact 6 through which currents flow in parallel with and opposition to a part of the movable arm 4.
