    摘要: A switching power supply is provided to supply an AC input voltage. The supply includes a control circuit configured to detect a voltage of the AC power source in a voltage waveform, and switch elements in a synchronous rectification switching mode in synchronization with polarities of the voltage waveform when the AC input voltage is equal to or greater than a predetermined voltage value. The control unit also operates the switching without synchronization with the polarities when the AC input voltage is smaller than the predetermined voltage value.

    摘要: A gate drive circuit including dead time control circuits delaying on periods of switching elements S1, S2 based on a control signal; driving circuits; and monitor circuits. Each of the monitor circuits includes a current source and an N-type FET in which the source is connected to the gate of one of the switching elements; the drain is connected to the current source; and a predetermined voltage is applied to the gate. When an off state of one of the switching elements is detected, the N-type FET Qn outputs an off signal to the dead time control circuit on the other switching element side. Based on the off signal, the dead time control circuit on the other switching element side terminates an operation of delaying the on period of the other switching element.

    摘要: The present invention provides a retainer for a pipe connecting device, capable of being disengaged from a pipe without using any special disconnecting tool when disconnecting the pipe from the connector housing, and of remaining on a connector housing without being separated together with the pipe from the connector housing when the pipe is disconnected from the connector. A retainer (17) of an elastic material is interposed between a pipe (14) and a connector housing (15) in a known manner. When the pipe connecting device is in a connecting state, first catching edges (26a) of a pair of flexible catching parts (26) formed in a middle part of the retainer (17) are in engagement with a stopping protrusion (18) formed on the pipe (14), second catching parts (26b) lie in openings (20) formed in the connector housing (15) and are in engagement with support bars (19). Parts near the pair of second catching edges (26b) are connected integrally by fixed walls (28) serving as a spacing means. When operating knobs (25) formed opposite to each other on one end of the retainer (17) are pressed toward each other by fingers, parts near the pair of second catching edges (26b) serve as fixed fulcra, the first catching edges (26a) on one side of the flexible catching parts (26) opposite the side of the operating knobs (25) are displaced outward and are disengaged from the stopping protrusion (18) of the pipe (14). Then, the pipe (14) can be disconnected from the connector housing (15), and the retainer (17) remains on the connector housing (15).

    摘要: A main pipe is lined using a pipe lining material that blocks the opening of a lateral pipe branching from the main pipe. An in-pipe work robot is provided with a cutting nozzle for spraying a pressurized fluid material or pressurized granular material onto the pipe lining material of the main pipe. The cutting nozzle is moved to a predetermined position inside the main pipe and rotated about a vertical axis by a rotary mechanism to cut the lining material between the first and second pipes by the pressurized fluid material or pressurized granular material sprayed from the cutting nozzle in order to form an opening for communicating the main pipe with the lateral pipe. The cutting nozzle can be moved in desired positions to drill holes accurately without damaging the internal peripheral surface of the lateral pipe.
