The methods comprise the step of subjecting a quantity of edible foams to a brief exposure to high intensity (>110 V/cm) microwave field for about 5 to 30 seconds.  The high intensity microwave heating heat sets the foam to provide a stable structure.  Thereafter, the heat set structures are then dried using low temperature dried to desired moisture contents ranging from about 1% to 6%.        The microwave heat set foam pieces exhibit a homogeneous (i.e., without voids or irregularities) texture and a crisp, light eating quality.  The edible foam products exhibit extended bowl lives and find particular suitability for use as additives to ready-to-eat cereal products.  Preferred embodiments comprise high levels of fruit puree solids which by virtue of the short heat setting and low temperature drying steps exhibit high natural flavor levels.

Title: Cross-talk canceller for optical disk reading mechanism
Inventor: KAWASAKI SATOSHI
IPC: G11B7/005
Filed: 1994-05-18
Abstract: In a cross-talk canceller for an optical disk reading mechanism, reproduced signals from three optical detectors installed in an optical head are level-adjusted by three amplifiers. Output signals from two of the amplifiers are delayed by respective delay circuits. An output signal of one delay circuit and an output signal of one amplifier are subtracted from an output signal of a second delay circuit by a subtracter, such that a reproduced signal from which cross-talk resulting from an adjacent track on an optical disk has been removed is obtained. The delay amounts of the delay circuits are set according to delay control signals. The delay amounts are set when accessing a fixed pattern recording area disposed on a predetermined position of an optical disk. A control circuit measures a time difference between the output signal of one detector and the output signal of a second detector to output a delay control signal. The control circuit measures a time difference between the output signal of the two detectors to generate the delay control signal.
