Further, the user of the hose manages the name of the manufacturer of the hose, the starting date of use of the hose, the replacement time, etc. based on this number.

[0004]

However, if the manufacturing lot number is printed and displayed on the surface of the hose as described above, the print becomes faint as it is used, or the print becomes dirty and the number cannot be read, and the replacement is required. Sometimes it was not possible to grasp the timing.

When the replacement time is unknown in this way,
If you are using a hose that has passed its replacement period, the hose may be damaged and cause an accident.

In view of the above problems, an object of the present invention is to provide a hose capable of reliably managing the production lot number, quality, history, etc. even after the consumer starts using the hose.

[0007]

In order to achieve the above object, the present invention provides a receiving antenna, a transmitting antenna, and an electromagnetic wave of a first frequency inputted to the receiving antenna. A rectifying circuit that generates a predetermined DC current, a semiconductor memory unit that operates by the DC current output from the rectifier circuit, and a semiconductor memory unit that operates by the DC current output by the rectifier circuit and reads stored information in the semiconductor memory unit. Information consisting of a central processing unit and a high frequency transmitting unit which operates by a direct current output from the rectifier circuit and supplies the information read by the central processing unit to the transmitting antenna as a high frequency signal of a second frequency. We propose a hose in which a memory element is provided at a predetermined location.

As a result, the central processing unit stores the information stored in the semiconductor storage unit while the electromagnetic wave of the first frequency is being received, that is, while the direct current is being supplied from the rectifier circuit. The read information is supplied to the transmitting antenna as the high frequency signal of the second frequency by the high frequency transmitting unit and is radiated as an electromagnetic wave. Therefore, by radiating the electromagnetic wave of the first frequency from the outside of the information storage element, the stored information in the information storage element is emitted as the electromagnetic wave of the second frequency almost at the same time and is received. As a result, it is possible to obtain stored information such as the manufacturing date, manufacturing number, manufacturing lot, and manufacturing factory.

Therefore, when a failure occurs, it is possible to confirm the identity of the hose 1 itself, and even if the printed display of the manufacturing lot number that has been conventionally used is faint or dirty, the hose 1 itself can be confirmed. The identity can be easily confirmed.

Further, since the information stored in the information storage element 2 can be easily updated or rewritten, it can be effectively utilized when the history of the hose 1 is desired to be retained. For example, when a failure occurs and the repair is performed, information such as the date and time of the repair, the factory for carrying out the repair, the content of the repair and the like can be written in and read out from the information storage element 2 at any time, and the individual hose 1 can be read.
