High temperature ultrasonic transducers for monitoring of micro-molding
Bibliographic record
Abstract
Thick film (90/spl mu/m) piezoelectric ceramic ultrasonic transducers (UTs) have been successfully deposited on a barrel and a mold insert of a micro-molding machine by a sol-gel spray technique. The ball-milled bismuth titanate fine powders are dispersed into PZT solution to achieve the gel. The gel is then sprayed onto the substrate at room temperature. The films with desired thickness have been obtained through multilayer coating approach. Piezoelectricity is achieved using a corona discharge poling method. These UTs can operate at more than 500/spl deg/C. The center frequency of ultrasound generated is 13 MHz and 6 dB bandwidth is 13 MHz. In the pulse/echo mode the ultrasonic signals have a signal to noise ratio of more than 30dB. The ability of these UTs to monitor the polymer properties in real-time at the barrel and the mold insert of the micro-molding machine during processing is demonstrated.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
