摘要:
A water meter of the present invention may accurately measure a flow rate and reduce power consumption. The water meter includes a body including an inlet unit and an outlet unit, an impeller unit provided to rotate due to a fluid flowing in the body, a cover member that covers one side of the impeller unit and includes a guide groove formed therein, and sensors that are provided on one side and the other side of the cover member and are spaced apart from each other to face each other. The impeller unit includes blades interfering with the fluid, a shaft forming a rotational center of the blades, and a cut-off unit that extends from one side of the plurality of blades to be inserted into the guide groove, and selectively cuts off signal transmission between the plurality of sensors.

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.

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.

A Bluetooth system includes a set-top box transmitting/receiving data to/from a communication terminal, and a Bluetooth module installed on the outside of the set-top box and connected to the set-top box through a first cable, and converting the data into a predetermined format. The Bluetooth module is installed at a position to meet an optimal data receiving condition. The set-top box includes a first connection unit to which the first cable is connected. A failure in the data communication of the set-top box caused by the limitation in the installation location and area, such as walls or other blocking structure surrounding the set-top box, can be addressed.

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.
