Abstract: A container locking device and a piggyback transport vehicle are provided. The container locking device includes: a support, the support being provided with an accommodating space; a locking structure, a first end of the locking structure being hinged with the support, the locking structure having a locking position extending out of the accommodating space and an avoiding position retracted into the accommodating space; and a support structure, a first end of the support structure being hinged with a second end of the locking structure; wherein in a direction away from the locking structure, the support structure has a retraction position and a support position which cooperates with the support.

Abstract: An underwater rapid repair material for marine steel structure comprises: 20 to 50 parts by weight of an alkali activation material, 3 to 12 parts by weight of a fast hardening waterborne polymer curing agent, 2 to 8 parts by weight of a fast hardening waterborne polymer precursor, 30 to 100 parts by weight of an aggregate, 1 to 5 parts by weight of an activator and 3 to 20 parts by weight of a water. The underwater rapid repair material provided by the present invention is not dispersed and segregated in water, with an initial setting time as low as 0.5 hours and a final setting time as low as 1.1 hours, after pouring 3 hours, the compressive strength and flexural strength can reach about 60 MPa and 10 MPa respectively, and has high bonding strength to steel and is not easy to fall off after solidification.

Abstract: The present disclosure provides a container locking device and a piggyback transport vehicle.

Abstract: A heat generating device of a toaster includes a frame, two side electric heating plates mounted at two sides of the frame, and a middle electric heating plate disposed between the two side electric heating plates. A baking chamber is formed between every adjacent two of the electric heating plates for baking sliced bread. Each of the electric heating plates includes a substrate and a heat-generating metal film. A surface of the substrate of each of the two side electric heating plates, facing the baking chamber, is bonded with the heat-generating metal film. Front and back surfaces of the substrate of the middle heating plate are bonded with the heat-generating metal film.

Abstract: The present invention relates to an optical interferometer based on a Mach-Zehnder interferometer that can be used as an optical channel interleaver in wavelength division multiplexed (WDM) and dense wavelength division multiplexed (DWDM) optical networks. Optical channel interleavers/de-interleavers combine sets of WDM and DWDM channels for transmission over a network and/or separate WDM and DWDM signals into sets of channels with more convenient channel spacing for further de-multiplexing. The interferometer according to the present invention utilizes a ring resonator in each arm thereof as a phase shifter to provide a flat-top wavelength response with wide pass-bands and stop-bands.
