Abstract: A furniture item includes a main body with an electrical device installed thereon. A power line electrically connects the electrical device to an external power source and is concealed in a power line channel formed in one or more of the walls of the main body. A switch may be connected to the main body and electrically connected to the electrical device, for controlling the electrical device. A main body door moveable from a first position to a second position may trigger the switch to enable and disable electrical connection between the external power source and the electrical device.

Abstract: The disclosure relates to a smart furniture controller with voice recognition, including a controller body and a control circuit. The control circuit is disposed in the controller body. The control circuit comprises a main control unit, a voice recognition module, an operation panel, a control output interface and a power module. The voice recognition module is connected to the main control unit; a microphone and a loudspeaker are connected to the voice recognition module; the operation panel is connected to the main control unit, and the control output interface is connected to the main control unit. The disclosed embodiments integrate a voice recognition module in the controller. Voice commands can be recognized through the voice recognition module, allowing to control the smart furniture via voice, and making the operation simpler and more convenient.

Abstract: Provided are a polishing composition capable of effectively reducing or eliminating a step difference on a surface of an object to be polished consisting of a single material, a method of using such a polishing composition, and a method of producing a substrate. The polishing composition of the present invention contains an abrasive grain, a pH adjusting agent, a dispersing medium, and at least one kind of first water-soluble polymer having a lactam structure and at least one kind of second water-soluble polymer containing an alkylene oxide represented by the following Formula (I) in the structure, ?CxH2xO?n??(I) (in the Formula (I), X is an integer of 3 or more and n is an integer of 2 or more.).

Abstract: To provide a means for suppressing the rate of dissolution of tungsten while sufficiently removing the impurities remaining on a surface of a polished object to be polished having a layer containing at least tungsten, and tetraethyl orthosilicate or silicon nitride. To provide a composition for surface treatment, which contains a polymer compound having a sulfonic acid (salt) group, at least one compound selected from an amino acid and a polyol, and a dispersing medium, and is used for treating a surface of a polished object to be polished having a layer containing at least tungsten, and tetraethyl orthosilicate or silicon nitride.

Abstract: To provide a composition for surface treatment capable of treating a surface of a polished object to be polished having both of a silicon-silicon bond and a nitrogen-silicon bond by sufficiently removing defects on the surface of the polished object to be polished. The composition for surface treatment contains a nonionic water-soluble polymer (A) having a main chain including only a carbon atom or a main chain consisting of a carbon atom and a nitrogen atom, and an anionic water-soluble polymer (B) having a main chain including only a carbon atom and a side chain having a sulfonic acid group or a group having a salt thereof or a carboxyl group or a group having a salt thereof, and being bonded to the main chain including only a carbon atom, and the composition is used for surface treatment of a polished object to be polished containing a silicon-silicon bond and a nitrogen-silicon bond and a pH of the composition is less than 9.0.
