An exhaust gas purifying device for an internal combustion engine includes an inflow case provided with an inlet pipe, a catalyst case in which an oxidizing catalyst for dosing is housed, a filter case in which a soot filter is housed, and an outflow case provided with an outlet pipe, and is attached to an attached target at two attachment points mutually spaced in the axial direction of the cases. At one of the two attachment points, which is defined on the catalyst case, the catalyst case is firmly fixed. At the other attachment point, which is defined on the filter case, the filter case is attached slidably in the axial direction.

Exhaust gas purifying device for internal combustion engine

A control unit is disclosed for controlling a refrigerating machine in such a way that a refrigerating power exceeding the required performance is secured while the control unit has a function of bypassing hot gas by means of a hot gas bypass line. A temperature-responsive valve is mounted in the hot gas bypass line in addition to a pressure regulating valve. If a preset temperature Tr of a brine becomes equal to or higher than a given temperature (0&deg; C.), the temperature-responsive valve opens the bypass line. If the preset temperature Tr becomes lower than the given temperature, the temperature-responsive valve closes the bypass line.

Control unit for refrigerating machine

A temperature control system which performs control of an object whose temperature is to be controlled as accurately as possible. The system comprises: a chiller located in a fluid circulating and supplying system, for cooling a thermal fluid returning from a vacuum chamber, a first flow control valve located in the fluid circulating and supplying system in a position between the chiller and the vacuum chamber, a bypass passage for splitting and supplying thermal fluid returning from the vacuum chamber to a position between the first flow control valve and the vacuum chamber, before it reaches the chiller, a second flow control valve located in the bypass passage, and a halogen lamp heater located in the fluid circulating and supplying system in a position between a confluence point of the bypass passage and the vacuum chamber, for adjusting the temperature of the thermal fluid passing therethrough to a set temperature.
