Abstract: In the present uninterruptible power supply apparatus, in a switching period in which a bypass power feed mode is switched to an inverter power feed mode, a semiconductor switch is turned on, a first electromagnetic contactor is turned off, a second electromagnetic contactor is turned on and, in this state, an inverter is activated to start a lap power feed mode, and the semiconductor switch is turned off to end the lap power feed mode. Accordingly, the lap power feed mode can be completed in a short time to reduce an increase of a terminal-to-terminal voltage of a capacitor and thereby prevent the terminal-to-terminal voltage of the capacitor from exceeding an upper limit voltage.

Abstract: In an uninterruptible power supply apparatus, AC current, which includes a feedback component having a value corresponding to deviation between terminal-to-terminal voltage of a capacitor and reference voltage, and a feed forward component obtained by multiplying load current by a gain, is passed into a converter such that the terminal-to-terminal voltage of the capacitor becomes the reference voltage. The gain is set to a first gain in an inverter power feed mode and a bypass power feed mode, and the gain is set to a second gain smaller than the first gain in a switching period of switching between the inverter power feed mode and the bypass power feed mode, to prevent the terminal-to-terminal voltage of the capacitor from exceeding an upper limit voltage in a lap power feed mode.

Abstract: It is an object of this invention to reduce air resistance, which occurs when a packing is mounted in the mounting groove of a spool. Reducing this air resistance facilitates the mounting operation and prevents compressed air from being contained in a groove bottom space, and thus prevents the packing from floating. To achieve this object, a packing mounting groove 14 consisting of a wide portion 14a and a narrow portion 14b is formed in a seal land 13 in the spool. In addition, a packing 11 includes on both sides of its second portion 11b, which is fitted on the narrow portion 14b, a seal lip 18 that contacts the groove wall of the narrow portion 14b in a gas-tight manner such that air is prevented from flowing into the groove bottom. Furthermore, a lip width (f) representing the distance between both seal lips 18 and 18 under a non-seal condition is set the same as or smaller than the width (a) of the wide portion 14a of the mounting groove 14.

Abstract: A speed-reducing valve assembly is provided in an air passage through which compressed air is discharged when a pneumatic actuator is decelerated. The speed-reducing valve assembly comprises a three-way valve actuated by a signal generated when the actuator has reached the point where deceleration is started, a relief valve through which the compressed air in the passage is let out when the air pressure has reached the preset level, and a check valve that allows only the admission of compressed air into the same passage. The signal-actuated three-way valve brings the air passage of the actuator into communication with the passage in which the relief valve and check valve are provided. When the signal generated when the actuator has reached the deceleration starting point is fed to the speed-reducing valve assembly, the exhaust passage of the actuator communicates with the relief valve and check valve.
