Cooking fresh sweet corn in boiling water is simple: Shuck the corn. Bring water to a boil in a large pot and boil the corn for five to 10 minutes, depending on how soft you like your corn. You can cook fresh sweet corn in the microwave in just minutes. Shuck the ears and wrap them in plastic cling wrap. Microwave them for 90 seconds per ear.
PDC drill bits. Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts. When fixed-head bits use PDC cutters, they are commonly called PDC bits.
PTC stands for âPositive Temperature Coefficientâ. PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature. PTC thermistors are divided into two groups, based on the materials used, their structure and the manufacturing process.The first group of PTC thermistors is comprised of silistors, which use silicon as the semiconductive material. They are used as PTC temperature sensors for their linear characteristic.The second group is the switching type PTC thermistor. This type of PTC thermistors is widely used in PTC heaters, sensors etc. Polymer PTC thermistors, made of a special plastic, are also in this second group, often used as resettable fuses.The switching type PTC thermistor has a highly nonlinear resistance-temperature curve.hey are used as PTC temperature sensors for their linear characteristic. The second group is the switching type PTC thermistor. This type of PTC thermistors is widely used in PTC heaters, sensors etc. Polymer PTC thermistors, made of a special plastic, are also in this second group, often used as resettable fuses.
