Abstract: An ozone generator (100) includes: a flow path (1) through which gas flows from an inlet (5) to an outlet (6); an ozone generation unit (3) disposed in the flow path (1); and an ozone sensor (4) disposed in the flow path (1) and upstream of the ozone generation unit (3). The flow path (1) has an upstream-side flow path (130) that forms a gas passing space (AR) located upstream of the ozone generation unit (3) and through which the gas flows from one side to another side in a predetermined direction. The inlet (5) is disposed closer to an outer circumferential portion (131) of the upstream-side flow path (130) than the ozone sensor (4).

Abstract: A plasma generating device with a pair of plate-like conductor parts each having a plurality of through-holes passing between main surfaces are opposed to each other with a predetermined gap therebetween. A gas is flowed into the through-holes from one side of the pair of plate-like conductor parts. Plasma discharge is generated in the gap by applying a high-frequency voltage between the pair of plate-like conductor parts and the generated plasma is flowed out to the other side of the pair of plate-like conductor parts.

Abstract: A substrate held by a holder is housed in a treatment chamber. An electrode set is disposed so as to face a surface of the substrate. Each electrode set consists of a first electrode section and a second electrode section. Each of the first and second electrode sections consists of high-frequency electrodes and/or ground electrodes. Process gas emitted through introduction ports is fed between the electrodes to generate plasma. The generated plasma is used to remove contaminated substances adhered to the surface of the substrate.

Abstract: Systems and methods for detecting a short in an electrical distribution system are disclosed. In one embodiment, a determination is made as to whether a short condition is satisfied based on a change in a voltage in a wire harness coupled to a first side of a switch. The determination of whether a short exists is made in response to determining whether the short condition has been satisfied for at least a threshold time. The threshold time is dependent on a change in a voltage of the wire harness coupled to a second side of the switch.
