Abstract:
A method of manufacturing an optical waveguide is disclosed. The method in accordance with an embodiment of the present invention includes providing a carrier, fixing a base substrate to the carrier by using a first insulation layer such that the base substrate is directly stacked on the carrier, stacking an optical waveguide layer on at least one of the base substrate and the first insulation layer, and severing the base substrate such that the base substrate and the optical waveguide layer are separated from the carrier. Accordingly, the optical waveguide layer can be formed with a uniform thickness since wrinkles in the base substrate supporting the optical waveguide layer are prevented from forming during the manufacturing process.
Abstract:
Provided is a virtual space providing system that may provide a virtual space to a terminal of at least one user, the system including a monitor configured to monitor whether an application or a program included in each terminal of the at least one user is executed and a real-time operation of the executed application or the program and output a result of the monitoring, a specifier configured to receive the output from the monitor, specify an individual step of the operation of the executed application, and output a request to generate a virtual space for the specified individual step, and a space generator configured to receive the output from the specifier and generate the virtual space for the specified individual step.
Abstract:
A surgical instrument providing a passage to upper and lower portions of the flexor retinaculum, comprises: a hollow cannular needle having an end capable of penetrating the skin; and a blunt rod which enters the cannular needle and moves under the skin in correspondence to the passage, wherein the cannular needle can move along the blunt rod moved under the skin so as to provide the passage to upper and lower portions of the flexor retinaculum.
Abstract:
The present invention provides an optical flexible printed circuit board comprising: a base layer; an optical waveguide pattern disposed on a partial region of the base layer; an insulating layer which is disposed on the base layer with the optical waveguide pattern and has a surface profile bent by the optical waveguide pattern; and circuit wires disposed on one surface of the base layer.
Abstract:
A cleaning apparatus using a gas-mixed liquid includes a first inlet port into which a liquid supplied from the outside is introduced, a second inlet port into which a gas to be mixed with the liquid introduced from the first inlet port is introduced, a mixing chamber in which the liquid introduced from the first inlet port and the gas introduced from the second inlet port are mixed with each other, and an outlet port through which the liquid mixed with the gas in the mixing chamber is discharged. According to the present invention, it is possible to efficiently remove slime such as scale generated in a variety of industrial conduits in which liquids flow, and germs, etc. deposited in various conduits.
Abstract:
An apparatus for preventing the formation of beer stones and a gas-induced phenomenon, in which foamy beer spurts out of a draught beer container, is disposed in a pipe between the draught beer container and a draught beer dispensing apparatus so as to prevent the gas-induced phenomenon from occurring when the beer is discharged from the draught beer container to the draught beer dispensing apparatus, and to remove and prevent the formation of beer stones deposited on the inner surface of the pipe, between the draught beer container and the draught beer dispensing apparatus, or on the inner surface of the draught beer dispensing apparatus.
