Abstract: Provided are a straddle type monorail vehicle in which a center pin provided in a vehicle body can be mechanically fastened to a center pin holding portion provided in a bogie via a cushioning rubber with a small number of work steps, and an assembly method thereof. The center pin has a hollow shape in which both ends are opened, and includes a large cylindrical portion on a bolster beam side and a small cylindrical portion that is connected to the large cylindrical portion and that is coaxial with the large cylindrical portion, the center pin holding portion is elastically supported by a bogie frame forming a frame body of the bogie, and has a hollow portion into which the small cylindrical portion of the center pin is inserted. A fixing metal fitting has a cylindrical rod shape inserted through the center pin that includes first and second threaded portions.

Abstract: The method to control cleanroom conditions, including zone particle concentration, occupancy status, and heating, ventilation, and air conditioning (HVAC) system conditions, includes detecting a zone particle concentration, an occupancy status, and HVAC system conditions. The cleanroom includes the HVAC system in communication with the zone of the cleanroom and with a computer processor as a control unit of the cleanroom. The zone particle concentration, the occupancy status, and the HVAC system conditions are communicated to the computer processor, and a desired zone particle concentration is determined based on a range of desired HVAC system conditions with model predictive control. A first control signal to the HVAC system based on the occupancy status, the zone particle concentration, and the desired zone particle concentration is determined. The first control signal is communicated to the HVAC system, and the HVAC system activates according to the first control signal.

Abstract: The control system for controlling air volume to maintain a desired concentration of airborne contamination in a cleanroom supplied by a HVAC system being operative to supply treated air to the cleanroom includes a sensor for a concentration of non-viable particles and/or viable particles in real time or near real time; and a processor for comparing the sensed concentration of non-viable particles and/or viable particles against the desired concentration of airborne contamination. At least one control signal is outputted to the HVAC system based on the comparison.
