Abstract: Disclosed is a hydroculture pot that can store an optimum amount of water at which a water level is appropriate for a depth of roots. A soil culture pot, having a supply and drainage hole that enables supplying and draining of water in a bottom portion, is used and a partitioning wall, vertically partitioning an interior of the pot main body in a watertight manner to store an optimum amount of water at which a water level is appropriate for a depth of roots of a spider plant, is disposed at an inner circumferential surface of a pot main body. An interior of the pot main body is filled with hydroculture soil and the optimum amount of water is stored in the pot main body so that the water level appropriate for the depth of roots of spider plant planted in the pot main body is a maximum level.

Abstract: To provide a wheel support bearing device, in which the status of actual use is detected and stored as a history, an IC tag (9) capable of a contactless communication is affixed to the wheel support bearing device. This IC tag (9) is rendered to be a sensor incorporated IC tag integrated with or electrically connected with a sensor for detecting an object to be detected of the wheel support bearing device and a detection of the sensor is inputted through an input channel separate from a channel for the contactless communication. The sensor referred to above may be, for example, a coil and a magnet (10) capable of passing in the vicinity of the sensor incorporated IC tag (9) by the effect of a relative rotation.
