Filter with electrostatic discharge mitigation sleeve

A DC power supply device including a DC/DC converter having FETs each driven by a drive transformer. A voltage from a single drive power supply disposed in common for the FETs is divided into positive and negative biases to be applied to the FETs, and an operational state of the FETs is detected based on voltage signals. A sequence circuit turns on an input from a three-phase AC power supply by driving a relay circuit at a time point when it is confirmed that the FETs have normally started stable ON/OFF operation, and drives a power factor improvement circuit, which converts AC voltage from the three-phase AC power supply into a DC voltage by simultaneously performing full-wave rectification and power factor improvement.

A purification module is provided comprising a plurality of purification cartridges, a support for the cartridges, a manifold and a bowl. In one embodiment the support for the cartridges has two pitched partial screw threads on opposing surfaces which mate with pitched screw flights on the manifold when the partial screw threads are rotated into the screw flights. The support includes fluid passageways for directing filtered fluid from the filtration cartridges, through the support and into the manifold. In another embodiment, a purification module is provided comprising a purification cartridge, a manifold and a bowl. The purification cartridge has two pitched partial screw threads on opposing surfaces of the cartridge outlet which mate with screw flights on the manifold when the partial screw threads are rotated into the mating screw flights.

Filtration module

A coated film forming method is capable of readily forming a coated film of a thermoplastic material on a coated region of an inner peripheral surface of a cylinder. A nozzle, through which a molten paste of a thermoplastic material kept molten is discharged, is disposed toward an inner peripheral surface of a cylinder. The nozzle is moved along a rotational central line of the cylinder while rotating the cylinder and discharging the molten paste from the nozzle. Centrifugal force acting on the cylinder being rotated leads to spreading of the molten paste applied to the inner peripheral surface of the cylinder. Viscosity of the molten paste, a rotational speed of the cylinder and a speed of movement of the nozzle are set so as to keep the molten paste discharged from the nozzle from being scattered to a region other than the coated region.
