Title: Veneer dehydrating apparatus
Inventor: KOBA YOSHINORI
IPC: F26B5/14
Filed: 2001-09-18
Granted: 2005-11-15
Abstract: A veneer dehydrating apparatus which has a pair of rotatable dehydrating roll assemblies disposed one above the other and having their axes extending parallel to each other, at least one of which is positively driven.  The paired roll assemblies includes a first roll assembly having formed on the peripheral surface thereof a number of tooth-like projections extending radially outward from the peripheral surface and a second roll assembly having a steel core shaft which is clad with covering of elastic material such as urethane rubber with a predetermined thickness. The axes of the roll assemblies are spaced radially to form a clearance or a nip between the peripheral surfaces thereof which is smaller than the thickness of the veneer sheet to be dehydrated.      The second roll assembly has formed therein a number of annular grooves spaced axially of the second roll assembly at an interval of 50 mm or less and each having a width of 10 mm or less, thereby having a number of sectional elastic portions which are separated by any two adjacent annular grooves and each of such elastic portions being deformable independently of other similar portions.

Abstract: A traveling-wave device is provided with the conventional moving pistons eliminated. Acoustic energy circulates in a direction through a fluid within a torus (30). A side branch may be connected to the torus for transferring acoustic energy into or out of the torus. A regenerator (32) is located in the torus with a first heat exchanger (34) located on a first side of the regenerator downstream of the regenerator relative to the direction of the circulating acoustic energy; and a second heat exchanger (36) located on an upstream side of the regenerator. The improvement is a mass flux suppressor (46) located in the torus to minimize time-average mass flux of the fluid. In one embodiment, the device further includes a thermal buffer column (70) in the torus to thermally isolate the heat exchanger that is at the operating temperature of the device.

Abstract: A semi-automatic opener for a jar closed by a threaded cover comprises a base for receiving a jar thereon and an upper portion superimposed to the base. A  first turntable is rotatably mounted to the base via a rotatable shaft that is coupled to a motor. A first toothed rack is mounted to the first turntable and has a first central gear coaxially mounted to the rotatable shaft and a first pair of rack elements each interlocked to the first central gear for reciprocating movement towards and away each other upon rotation of the first central gear.  A first pair of jaws is respectively secured to a rack element of the first toothed rack and allows immobilizing the jar. The second portion also includes a pair of jaws mounted to a second toothed rack. In operation, the jar is positioned onto the base and the second portion is lowered for abutment with the cover. Then, activating the motor causes the rotation of the rotatable shaft, which in turn causes the rotation in unison of the first and second turntables with the jar.    Since the rotation of the second turntable causes the closing of the upper jaws on the cover of the jar, the rotation of the jar is stopped when the second pair of jaws grips the cover. The jar and the upper portion of the jar opener are then immobilized while the lower jaws move towards the jar since the motor is still energized and the first turntable is fixedly mounted to the rotating shaft.  The cover being immobilized, the rotation of the jar results in its opening.

Title: Improving vision and retinal imaging
Inventor: WILLIAMS DAVID R
IPC: G02C7/04
Filed: 2001-04-16
Granted: 2010-03-30
Abstract: A method for improving the visual performance of a person involves correcting higher-order monochromatic aberrations in combination with the correction of chromatic aberration. Such correction results in a visual benefit greater than that realized by correcting only the higher-order monochromatic aberrations or the chromatic aberration alone. The higher-order monochromatic aberrations are corrected by introducing appropriate phase profiles to compensate for the wavefront aberrations of the eye (107). This compensation can be provided by contact lenses (152), IOLs, inlays and onlays having appropriate surface shapes or by corneal shaping achieved through refractive surgery or other techniques. Chromatic aberration can be corrected by spectral filtering or artificial apodization. An apodization filter is described that provides a non-uniform amplitude transmission across the pupil of the eye. Contact lenses or other ocular devices for correcting higher-order monochromatic aberrations may include an appropriate apodization filter for correcting chromatic aberration, or an external optical device for correcting chromatic aberration may be used in combination with a contact lens, etc. for correcting the higher-order monochromatic aberrations. A device and method for improved retinal imaging is also described.
