摘要： [Object] To provide a temperature adjustment device capable of gradually changing the temperature of a load to a target temperature while adjusting the temperature of the load to the target temperature in the middle of temperature adjustment.
[Solution] A time-dependent set temperature Tn of a load W is calculated from a target temperature gradient Sa at each (elapsed time) of a plurality of timings within a target reach time period td (S3), and the time-dependent set temperature Tn is compared with a time-dependent measured temperature Tm inputted from a measurement input unit 50 (S5). A control output unit 53 controls a heating unit 3 and a cooling unit 4 based on a result of comparison between the time-dependent set temperature Tn and the time-dependent measured temperature Tm.

摘要： [Object] To provide an ejector and a vacuum generating device that are capable of reducing an installation space for a switching valve, the ejector, and a pipe and reducing the time and effort for an assembly work.
[Solution] An ejector 20 includes an ejector body 21 having an internal passage 27 and a negative-pressure generating mechanism 22 including a nozzle unit 23 that ejects compressed air and a diffuser unit 24 that generates a negative pressure by using compressed air ejected by the nozzle unit 23. The ejector body has a first attachment surface 20a to which a valve body 41 of a switching valve 40 is fixedly attached and a second attachment surface 20b to which a base body 18 of the manifold base 10 is fixedly attached. The first attachment surface has a first inflow port 28a for supplying compressed air to the negative-pressure generating mechanism by being connected to a first output port A of the switching valve, and this port communicates with the nozzle unit through a supply passage 28. The second attachment surface has a negative-pressure supply port 29c for outputting a negative pressure to the outside by being connected to a negative-pressure inflow port of the manifold base, and this port communicates with the diffuser unit through a negative-pressure communication passage 29.
