Patent number: 6951892Abstract: A continuous output system makes paper coating by combining an emulsifier with ASA particles having a mean average size in the low to sub-micron region. A turbine, pump, blender or other device exposes the ASA to a number of repeated episodes of high shear until the resulting ASA is in the form of particles having a mean average diameter in approximately the 1? range. The measure of the amount of high shear is identified by an energy factor index. A system for cooling the ASA enables the processing without causing a hydrolyzing of the ASA, even when a heated cooked emulsion is used.Type: GrantFiled: January 5, 2001Date of Patent: October 4, 2005Assignee: Norchem Industries, Inc.Inventor: Dennis Pardikes

Patent number: 6437835Abstract: A system for transferring video data includes a difference detector for detecting the difference between a current field information and the preceding field information. The preceding information is obtained from an entered interlaced video signal. An interpolator generates current display frame information in response to an interpolation based upon the current filed information with regard to an area of the video signal in which there is a difference value between successive fields that exceeds a predetermined threshold value. The interframe difference between the current display frame information and preceding display frame information is detected by the difference detector. Only the interframe difference is transferred over a system bus to enable a frame display to be presented on non-interlacing display device.Type: GrantFiled: October 2, 1997Date of Patent: August 20, 2002Assignee: NEC CorporationInventor: Susumu Sakamoto

Patent number: 6421207Abstract: In a contact type magnetic disk drive, a suspension spring or a load beam spring has a length smaller than 5 mm inclusive. This successfully reduces the amplitude of vibration to occur during seek. Also, a magnetic head slider has a mass of greater than 2 mg inclusive and is urged against the disk medium by a load of less than 1 g inclusive, so that a mean wear thickness and maximum amount of jump are reduced. For the reduction of the mean wear thickness and maximum amount of jump, the disk medium may include a lubrication layer having a thickness of greater than 5 nm inclusive, or the suspension spring or the load beam spring may have its thickness sequentially reduced from the side adjoining the spring support mechanism toward the slider. The disk drive reduces the wear of the slider and that of a magnetic disk, and achieves durability and reliability as well as high-density recording.Type: GrantFiled: December 19, 1996Date of Patent: July 16, 2002Assignee: NEC CorporationInventor: Akinobu Sato
