Abstract: A portable alarm device comprises a main body, an operation member and an actuating member. The main body contains an alarm sound emitting unit and a switch for operating the alarm sound emitting unit. The operation member is detached from the main body in an axial direction of the main body, and thereby the switch is closed. A locking member is provided in the main body and is displaceable between a locking position for preventing the detachment of the operation member and an unlocking position for allowing the detachment of the operation member. The actuating member drives the locking member to the unlocking position in accompany with either an action of grasping the main body in a radial direction by hand or an action of relative movement of the operation member and the main body grasped by hand in the axial direction of the main body.

Abstract: A screw vacuum pump which allows reduced power, lower inside gas temperature, and reduced discharging time. The pump has a pair of screw rotors rotatively engaged with each other in a pump casing to discharge a gas along a longitudinal direction of the pump. Each rotor has three types of helical teeth serially located in a longitudinal direction of the rotor and different from each other in theoretical displacement volume. A bypass conduit communicating with a delivery side of the pump is connected via a first check valve to a first intermediate space defined between the first helical teeth and the second helical teeth and via a second check valve to a second intermediate space defined between the second helical teeth and the third helical teeth. The gas is compressed at the third stage to half the first stage volume before a discharge port opens.
