A pre-cure resistant powder resin binder for waferboard/oriented strandboard manufacture is manufactured from spray drying a liquid resin composition containing a low advanced phenol-formaldehyde resin and a water soluble oxo compound of boron. The spray dryability of the low molecular weight phenol-formaldehyde resin is enhanced by the addition of the oxo boron compound.

The present invention is a method for separating aromatics from saturates using a non-porous polycarbonate membrane. In a preferred embodiment, the polycarbonate membrane may be crosslinked.

Natural rubber latex compounds are modified by the addition of a high styrene content styrene-butadiene copolymer. The films prepared from these modified NR latex compositions exhibit improved tear strength and a good balance of other properties.

A motion vector sensor includes a motion vector sense section (11) in which an input signal of an image plane is subdivided into a plurality of sense domains so as to compute a motion vector of an image in each of said domains, a motion vector decision section (12, 20) for judging validity of the motion vector in each domain so as to decide a motion vector of an entire image plane, a vector reliab...

An object sensor (15) outputs an obstacle detection signal in response to passing of an obstacle. A central control unit (CCU 1) reads a 2-dimensional image from an imaging unit (17) in response to the obstacle detection signal. A detection area is obtained by subtracting a background image prestored in a memory (11) from the input 2-dimensional image. The detected image on a 2-dimensional plane i...
