Abstract: A solenoid valve manifold (10) includes a connector member (70) that is formed by integrating a base portion (71) with a first connector portion (80) configured to electrically connect a first conductive member (52) to a circuit board (41) and a second connector portion (90) configured to electrically connect a second conductive member (62) to the circuit board (41). The base portion (71) has a through-hole (72). The base (30) includes two engagement projections (46). The base portion (71) is elastically deformable in a direction intersecting an insertion direction when the two engagement projections (46) are inserted into the through-hole (72). The connector member (70) is configured to be attached to the base (30) when a part of the base portion (71) around the through-hole (72) is engaged with the two engagement projections (46).

Abstract: A butterfly valve to be placed on a pipe between a vacuum chamber provided with a pressure sensor and a vacuum pump is configured to control the pressure in the vacuum chamber. The butterfly valve includes a servo motor, a butterfly valve element to be rotated about a rod connected to the servo motor in an opening or closing direction, and a control unit to adjust an opening degree of the butterfly valve element based on a pressure value of the vacuum chamber detected by the pressure sensor. The control unit is provided with an abnormal vibration detection program configured to whether or not abnormal vibration is occurring in the servo motor based on a variation amount of the opening degree of the butterfly valve element within a monitoring time while at least the pressure value of the vacuum chamber is stable.

Abstract: Parts of a first coupling and a second coupling that protrude from manifold blocks each have the shape of an elongated tube. When the first coupling and the second coupling are viewed in the axial direction, the traverse direction of the first coupling and the second coupling agree with the arrangement direction of manifold blocks. A part of the tube insertion hole is a small diameter hole, which is a stadium-shaped hole. When the first coupling and the second coupling are viewed in the axial direction, the traverse direction of the small diameter hole agrees with the traverse direction of the first coupling and the second coupling.

Abstract: A temperature control system is used for controlling a temperature of a control target. The system includes: a first circulation circuit through which a first heat transfer medium circulates; a second circulation circuit that is independent of the first circulation circuit and through which a second heat transfer medium circulates; and a third circulation circuit that is independent of the first circulation circuit and the second circulation circuit and through which a third heat transfer medium circulates. The third heat transfer medium has a usable temperature range wider than usable temperature ranges of the first heat transfer medium and the second heat transfer medium.

Abstract: A pulse shot-type flow rate control device including first and second shutoff valves, a tank, a pressure sensor, and a controller is caused to perform two or more processes. In each process, the controller repeats pulse shots of alternately causing the first shutoff valve and the second shutoff valve to open and close, changes a way of the pulse shots based on a pressure difference between the pressure after filling and the pressure after discharge, and controls a volume flow rate. In each process, the controller stores, as an optimal filling time, a filling time when the volume flow rate is controlled to a target flow rate, and opens and closes the first shutoff valve by using the optimal filling time in a first pulse shot in the next process.
