Abstract: A hot-pressed member has a predetermined chemical composition. In the hot-pressed member, a steel sheet has a microstructure in which a prior austenite average grain diameter is 8 ?m or less, and martensite is present in a volume fraction of 95% or greater in a region within 30 ?m of a surface; a Ni diffusion region having a thickness of 0.5 ?m or greater exists in a surface layer; a standard deviation of Vickers hardness values is 35 or less; Mndif (mass %) in a sheet thickness direction ?0.20, where Mndif (mass %) is a degree of Mn segregation; and a tensile strength is 1780 MPa or greater.

Abstract: A pedestal includes a seating surface portion on which water dispenser is to be placed; legs defining, under the seating surface portion, a robot receiving space which a self-propelled cleaning robot for cleaning a floor surface can enter and exist, and in which the cleaning robot can be received; and a charging station provided in the robot receiving space for charging the self-propelled cleaning robot. The pedestal allows the owner of an existing water dispenser to easily find a place for both this water dispenser and a self-propelled cleaning robot.

Abstract: A water dispenser is provided which is, if water leakage should occur, capable of detecting such water leakage at an early stage. The water dispenser includes a dispenser tray disposed between the housing and the floor surface and vertically separating the housing from the floor surface. The dispenser tray includes a dispenser support surface on which the housing is supported, a peripheral wall surrounding the dispenser support surface, and a water leakage indicator disposed in a region surrounded by the peripheral wall, and configured to change between a water leakage alarm state and a non-water-leakage-alarm state depending on whether or not there is water.

Abstract: A water dispenser unit includes a water dispenser and a self-propelled cleaning robot, and the space for the water dispenser can be easily secured even in a limited living space. A robot receiving space is defined in the lower portion of the water dispenser such that the self-propelled cleaning robot can self-travel into and out of the robot receiving space. The water dispenser unit includes a charging station provided in the robot receiving space.

Abstract: A vibration sensing apparatus including an acceleration sensor 2 for outputting a sensing signal corresponding to a vibrating acceleration, a level discriminator 3 for generating an output when the output level of the signal from the acceleration sensor 2 exceeds a preset reference level, a display unit 4 for displaying the output of the level discriminator 3, a piezoelectric ceramic power generating unit 5 using piezoelectric ceramics for generating a charge when it is subjected to vibration, and a conversion unit 6 for converting the charge generated by the piezoelectric ceramic power generating unit 5 into DC power, the DC power being supplied to the level discriminator and to the display unit as power to be consumed by them.
