  • Patent number: 9410493
    Abstract: According to the invention, a particulate matter sensor is installed in an exhaust passage of an internal-combustion engine. A control unit for this internal-combustion engine detects a particulate amount in an exhaust gas through the exhaust passage in response to an output from the particulate matter sensor. Further, the control unit for the internal-combustion engine forms a particulate layer on electrode surfaces of the particulate matter sensor by applying a particulate capturing voltage between the electrodes during a first period. Further, the control unit maintains the formed particulate layer during a second period. It is noted here that the phrase “maintain the formed particulate layer” includes the meanings “maintaining the formed particulate layer as it is” and “inhibiting control to remove the particulate layer”.

    Abstract: A respirator leak detection system and method for increasing the sensitivity and accuracy of leak detection through the fit seal of a respirator. A charged particle separator is used to separate charged particles that pass therethrough and to draw charged particles away from an aerosol flow into a clean gas flow. The separator may also be configured as an aerosol concentrator that takes in a major aerosol flow and outputs a minor flow of higher particle concentration. Neutral particles having no charge, which may have passed through the filtering medium respirator and which are not indicative of fit seal leaks are not entrained in the output flow for subsequent detection, thus increasing the accuracy of the filter leak detection system.

  • Publication number: 20110197759
    Abstract: A method is described for treating gas exhaust from a polysilicon etch process, which uses a plasma abatement device to treat the gas. The device comprises a stainless steel gas chamber having a gas inlet for receiving the gas and a gas outlet. As the gas may contain a halocompound and water vapour, the chamber is heated to a temperature that inhibits adsorption of water on the surface within the chamber, thereby inhibiting corrosion of the gas chamber. The gas is then conveyed to the gas chamber for treatment, and the temperature of the chamber is maintained above said temperature during treatment of the gas.

    Abstract: A method of controlling the operation of an electrostatic precipitator (6) comprises utilizing a control strategy for a power to be applied between at least one collecting electrode (28) and at least one discharge electrode (26), said control strategy comprising controlling, directly or indirectly, a power range and/or a power ramping rate. The temperature of said process gas is measured. When said control strategy comprises controlling the power range, a power range is selected based on said measured temperature, an upper limit value of said power range being lower at a high temperature of said process gas, than at a low temperature. When said control strategy comprises controlling the power ramping rate, a power ramping rate is selected based on said measured temperature, said power ramping rate being lower at a high temperature of said process gas, than at a low temperature.

    Abstract: A reel-to-reel aerosol collection and storage system for capturing and storing a plurality of separate samples of aerosol particles using electrostatic precipitation technology for collecting such particles onto a tape mechanism for analysis at a future time. The particles are collected onto a region of the collection tape for a defined period of time and then that portion of the collection tape is advanced out of the collection zone and manipulated so as to form sealed pouches or pockets which can be either severed from the collection tape for individual storage in a temperature controlled storage container, or which can be stored on a take-up reel in a temperature controlled environment. The collected aerosol particles are stored with a buffer fluid to preserve and maintain the viability of the collected particles for future extraction and analysis. Several embodiments for forming sealed pouches or pockets and methods of storing the collected particles are disclosed.
