Patent CA-2162538-C (CA)
Inventor: HASEGAWA ATSUSHI
IPC: H04M1/60
Filed: 1995-11-09
Granted: 2001-08-07
Abstract: An echo cancelling system has two echo cancellers for cancelling a channel echo and a room echo, respectively. In order to obviate echo estimation errors, the echo canceller at the channel side performs estimation only when an input signal from a channel is absent and a microphone input signal is present. The echo canceller at the room or acoustic side executes estimation only when a microphone input signal i s absent and an input signal from the channel is present. A necessary amount of suppression is applied to either the receipt side or the transmission side until the echo canceller estimates an echo, so that a howling margin is guaranteed.

Title: Twin-roll type continuous casting method and device
Inventor: MATSUMURA YOSHIKAZU
IPC: B22D11/12
Filed: 1995-04-03
Granted: 2002-01-01
Abstract: This invention provides a twin-roll continuous casting method, and an apparatus therefor, which can produce a thin sheet having excellent mechanical strength by finely and homogeneously reducing the crystal grain size, having reduced variance of materials and having excellent surface roughness devoid of skin roughness, and which can reduce the cost of equipment.  A casting C obtained by solidification by using a pair of water cooling casting rolls 2a, 2b is subjected to temperature adjustment to a temperature zone in which an austenite structure exists in its matrix. Thereafter, the casting is rolled by an in-line rolling mill 5 at a temperature ranging from 850.degree.C to less than 1,350.degree.C after solidification and at a reduction ratio of 5 to 50%. In this way, overall variance of elongation of the steel material is kept within 5% in terms of the standard deviation.

The weld ring also provides an annular space to retain a quantity of lubricant for the splined connection. A flexible convoluted boot is provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. A first end of the boot is secured to the weld ring, while a second end of the boot is secured to the transition member. The boot prevents contaminants from entering into the splined connection between the transition member and the shaft portion of the yoke shaft. A sleeve cup is also provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. The sleeve cup includes a circular body portion having a relatively short, axially extending flange portion. The circular body portion of the sleeve cup extends over the open end of the transition member to prevent contaminants from entering into the splined connection between the transition member and the shaft portion of the yoke shaft through the interior of the driveshaft section. The flange portion of the sleeve cup is frictionally engaged between the inner cylindrical surface of the driveshaft section and the outer cylindrical surface of the transition member to retain it in position during use.

Title: Multiple data layer optical disk drive system with fixed aberration correction and optimum interlayer spacing
Inventor: ROSEN HAL JERVIS
IPC: G11B7/24
Filed: 1996-02-01
Granted: 2002-03-19
Abstract: A multiple data layer optical disk drive system has fixed aberration correction and uses a disk with maximum interlayer spacing for reduced interlayer crosstalk. In one embodiment the multiple data layer disk has a substrate with a thickness that is reduced by approximately one-half the thickness of the spacer layer that separates the first and last data layers.  The disk is designed to operate with a lens that has spherical aberration correction to compensate for the thickness of a conventional single data lay er disk. This allows the disk drive to handle multiple data layer disks as well  as to be backward compatible and thus handle conventional single data layer disks. The thickness of the substrate material plus one-half the thickness o f the spacer layer material (which may have a different index of refraction th an the substrate material) is equivalent, for purposes of spherical aberration correction, to the thickness of the substrate material used in the conventional single data layer disk. The focused spot with minimum spherical  aberration is thus located at the middle of the spacer layer rather than one  the first data layer. The spacer layer thickness is selected so that when th e focused spot is located on either the first or last data layer there is some  deliberately designed spherical aberration, although an amount that is acceptable. As a result the thickness of the spacer layer can be significant ly increased to thereby reduce interlayer crosstalk. In another embodiment the substrate thickness and spacer layer thickness are selected and then the len s is corrected for spherical aberration corresponding to the thickness of substrate material plus one-half the thickness of spacer layer material.</SD OAB>
