The application relates to the technical field of fastener assembly detection, in particular to a gasket type pressure sensor which comprises a gasket body, a pressure sensing element, a signal processing module and an energy supply module; the gasket body is similar in shape to a conventional gasket, and a sealing groove is arranged in the gasket body; the pressure sensing element is arranged in the sealing groove and is used for collecting pressure signals generated in the screw fastening process and converting the pressure signals into electric signals; the signal processing module is electrically connected with the pressure sensing element, is arranged in the sealing groove or is arranged at the edge or external position of the gasket body through a wire and is used for amplifying, filtering and analog-digital converting the electric signals. The gasket body is similar in shape to a conventional gasket, can directly replace a traditional gasket and is embedded between screws and connecting workpieces of various specifications, the existing assembly structure does not need to be changed, and no additional installation space needs to be reserved, so that the gasket is suitable for narrow spaces and precise assembly scenes.

This application provides an ion implanter, including a vacuum chamber, a temperature probe, and a lead tube. The vacuum chamber contains a target disk for supporting a wafer. The temperature probe includes a temperature sensor, a metal shield, and a cable. The temperature sensor is a non-contact type, mounted on the inner wall of the vacuum chamber and aligned with the surface of the wafer supported on the target disk. The metal shield covers the outside of the temperature sensor to shield it from interference from the ion beam. The cable transmits power and signals to the temperature sensor. The lead tube, a tubular structure, extends through the vacuum chamber to lead the temperature probe cable to the outside of the vacuum chamber. This application's technical solution enables real-time, reliable, and accurate temperature monitoring of the wafer supported on the target disk, ensuring that operators can promptly obtain the wafer's true temperature status and take rapid action in case of abnormal temperature increases to prevent damage to the wafer.

The application discloses an array consistency real-time monitoring and compensation method and system. A MEMS microphone is built in a non-central area 2-5 mm in front of a diaphragm of each loudspeaker unit to establish a factory reference sound pressure / phase database; a radiation sound pressure signal of each unit is collected in real time during operation, current frequency response and phase are calculated, and a deviation value is obtained by comparison with the reference; when the threshold is exceeded, the driving level / delay compensation amount is calculated in the full frequency band of 20Hz-20kHz, and automatic adjustment is performed; the aging trend is predicted through linear regression, and early warning is performed within 72 hours when the threshold is exceeded. After the unit linear array of the embodiment 8 is operated for 3 years, the sound pressure consistency is compensated from the deteriorated ±4.2dB to ±0.8dB, the phase consistency is compensated from ±18° to ±3°, and the directivity half-power angle is restored from 28° to 10.5°.
