Title: Environment-friendly high-temperature melt pressure transmitter
Inventor: YING YU
IPC: G01L9/02
Filed: 2022-11-09
Granted: 2023-10-25
Abstract: Disclosed is an environment-friendly high-temperature melt pressure transmitter, and relates to the technical field of pressure transmitters. The environment-friendly high-temperature melt pressure transmitter comprises a shell, a long rod, a capillary tube, a diaphragm and a pressure detection assembly. The capillary tube is filled with gallium - based alloy liquid, and the gallium - based alloy liquid comprises, by weight, 55 - 65% of gallium, 16 - 22% of indium, 10 - 15% of tin, 2 - 5% of lead and 1 - 3% of thallium. The capillary tube is made of a platinum - rhodium alloy material, and the size of an inner hole of the capillary tube is 0.25 mm. The leakage phenomenon is eradicated through the diaphragm and a welding process, and thus the risk that heavy metal pollution and mercury leakage endanger the human body is effectively avoided; and the transmitter can normally measure the pressure of a melt at the high temperature higher than 750°C.

Title: Integral two-axle magnetometer
Inventor: RUMENIN CHAVDAR
IPC: H01L43/06
Filed: 2012-12-19
Abstract: The integral two-axle magnetometer includes a Hall effect sensor and an interface block diagram, as well as the Hall effect sensor containing a semiconductor wafer (1) with p-type conductivity, on the one side of which is formed a deep and narrow n-type ring structure (2) with circular shape. On the upper side of the n-ring (2) is formed a chain of located at equal distances from each other 2k number of contacts with n-type conductivity, where k is an integer number. The three contacts (4, 5 and 6), respectively (23, 24 and 25) are input, as the first (4 or 23) and the third (6 or 25) are are at the same time also output. Through equal in value load resistors (8 and 9), the first contact (4 or 23) and the third contact (6 or 25) are connected to one terminal of a current source (3), the other terminal of which is connected to the second input contact (5 or 24). The interface block diagram comprises a measuring amplifier (15) whose input is connected trough two multiplexers (10 and 12) to the output contacts of the currently activated Hall effect sensor by the commutator (20). The interface block diagram contains also three more multiplexers (10, 11 and 12), each of which has 2k number of inputs; a clock generator (13) controlling synchronously the operation of all modules of the circuit; a clock divider (18), controlling counters (14 and 19) which via the commutator (20) are connected to the multiplexers (10, 11 and 12). The counters (14 and 19) are set to count synchronously with a difference between each other of 2k/4n-type ohmic contacts, forming two three-contact Hall effect sensors (4-5-6 and 23-24-25), arranged relative to each other in the n-ring at an angle of 90 degrees. The step of moving the two so-established three-contact Hall effect sensors (4-5-6 and 23-24-25) along the circular n-ring is one contact, with the angle between them always remains 90 degrees. The commutator (20) is controlled at twice the frequency of the clock speed of the counters (14 and 19), sequentially connecting the outputs of both counters to the control inputs of the multiplexers (10, 11 and 12) at each fixed state of the counters ( 14 and 19). The outputs of the circuit (16) are outputs (17 and 22) of the integral two-axle magnetometer.
