摘要:
The present invention relates to a water-in-oil-in-water multiple emulsion system and a method for preparation thereof, characterized by hydrodynamically stabilizing the multiple emulsion system by using hydrodynamic dual stabilization (HDS) technology. The HDS technology hydrophobizes water molecules in the internal aqueous phase by using a hydrogen bonding inhibitor and by improving the aggregating force between water molecules in the internal aqueous phase by using a water molecule aggregating agent.

Disclosed herein is a playing apparatus for audio book and voice card, which is capable of acoustically playing contents of an audio book and a voice card used for education such as language learning. The playing apparatus for voice card and audio book comprises a voice card sensing unit, an audio book page sensing unit, a voice card transfer unit, a memory including a voice card information storing unit and an audio book information storing unit, a digital information processing unit, a speaker, and a MCU for controlling operation of all components. By providing a control method when the voice card is inserted during the output of the audio book, remaining data of the audio book can be output after a voice card playing mode is executed, without occurrence of errors due to a careless manipulation of the user. Accordingly, since the manipulation of the playing apparatus for audio book and voice card is very simple, even infants/babies can manipulate the playing apparatus easily and conveniently without the occurrence of errors.

Disclosed is a mesh-type angle-adjustable faucet for a kitchen sink, which can control the angle stepwisely by crown gears arranged at contact surfaces of two tubes. The faucet includes: a raw water pipe; a water tap; flow rate controlling means; a first tube connected with the water tap and having a first crown gear fixed at an end portion of the water tap via fixing means for preventing an idle rotation; a second tube having a second crown gear engaged with the first crown gear of the first tube at an end thereof via fixing means for preventing the idle rotation, the other end of the second crown gear being connected with the raw water pipe; an elastic member for allowing the first and second crown gears to be in close contact with each other; and a watertight member arranged at the contact surfaces of the first and second tubes.

The present invention relates to an ultrasound imaging system, comprising: an ultrasound image signal providing unit for providing ultrasound image signals corresponding to an ultrasound image having preset horizontal and vertical lengths; an image processing unit for forming a first ultrasound image based on the ultrasound image signals and adjusting a size of the first ultrasound image to thereby form a second ultrasound image; and a display unit including a display region having a plurality of dots arrayed in horizontal and vertical directions, the display region being configured to display the first and second ultrasound images, wherein the image processing unit calculates a conversion value for enlarging or reducing the first ultrasound image based on a horizontal or vertical length of the first ultrasound image and a distance between the neighboring dots, and wherein the image processing unit applies the conversion value to the first ultrasound image to thereby form the second ultrasound image.
