Abstract: The present disclosure discloses a manufacturing method and a manufacturing device for an interconnection piece. The manufacturing method comprises providing a solder strip, and performing forming treatment on the solder strip to obtain a plurality of structural solder strips; and providing a flexible insulating substrate, and compounding the plurality of structural solder strips on the flexible insulating substrate at intervals to obtain the interconnection piece. Each structural solder strip is provided with two soldering portions and a connecting portion located between the two soldering portions, and the connecting portion is respectively connected to the two soldering portions; at least a part of the connecting portion is located on the flexible insulating substrate, and the two soldering portions extend out of the flexible insulating substrate.

Abstract: The present invention provides a flow duct type jet reactor and a process for preparing isocyanates using it. The flow duct type jet reactor situates flow ducts in inner feed pipe which form whirlpool and reinforce vortex, thereby amine steam rapidly admixes and reacts with phosgene, and the byproducts are reduced. In addition, the present process uses a jet-absorption apparatus which rapidly cools the high temperature gas discharged from the reactor to a temperature at which the product is thermally stable, and at the same time provides negative pressure for the reaction process of the system, and thus saving bulky vacuum system.

Abstract: A method and device for displaying an underwater detection image is provided, in which an ultrasonic signal having a predetermined beam width is periodically transmitted underwater, receives a signal reflected on a detection target object which moves underwater, generates information on the detection target object based on the received signal, and displays the information on a display module. The method includes periodically detecting the detection target object and a position thereof based on the received signal, coupling the same detection target objects by associating the same based on the detection target object and the position periodically detected, and associating a displacement symbol corresponding to a change in a position of the detection target object with the coupled detection target object, and displaying the displacement symbol at the detected position of the detection target object at least on a two-dimensional position coordinates displayed in the display module.

Abstract: A bottom watering-type cultivation device which supplies water from a refillable water vessel (20) provided at a lower portion of a flowerpot (1) to a plant in the flowerpot (1). The bottom watering-type plant cultivation device includes a flowerpot (1) having a bottom part projected upward at a predetermined section thereof to a predetermined height to define a nutrient solution feed space (3) under the bottom part of the flowerpot (1), a refillable water vessel (20) to contain a predetermined amount of water therein to supply the water into the flowerpot, a nutrient solution guide (30) removably installed in the nutrient solution feed space (3) of the flowerpot (1), a water absorbing unit (24) engaging with the nutrient solution guide (30), and a root intercept unit (12) to prevent roots of the plant from infiltrating into the nutrient solution feed space (3).

Abstract: The present invention provides a method of steam reforming a hydrocarbon over a spinel-containing catalyst at short residence times or short contact times. The present invention also provides spinel-containing catalysts. Surprisingly superior results and properties obtained in methods and catalysts of the present invention are also described.
