  • Patent number: 6903702
    Abstract: An antenna is provided as a substrate member, and, as with the antenna, a ground part is provided as a substrate member. The ground part includes a folded pattern formed of a copper foil provided on the surface of a substrate material. When a folded pattern in the antenna and the folded pattern in the ground part are configured in a length of ?/4, a pseudo-antenna having a length of ?/2 can be formed. In this case, the antenna gain is about 2 dB, that is, the radiation of the radio wave can be improved. At the same time, the antinoise properties and the arrival distance of the radio wave can be improved. That is, the above construction can realize radio equipment which can stably radiate radio waves even under ungroundable conditions and, at the same time, can realize good characteristics even under low transmission output conditions.

  • Publication number: 20040252959
    Abstract: A temperature recording part is provided within a junction box such as an information box. The temperature recording part includes a memory for storing temperature and time signals. By virtue of this construction, the temperature within the junction box can be reliably recorded without undergoing the influence of any unfavorable phenomenon such as occurrence of noises in the course of the transmission of temperature signals, and the junction box provided remote from a control center or the like can be controlled based on the abnormality of the temperature within the junction box, whereby the junction box can be maintained in a normal state.

  • Patent number: 6742349
    Abstract: Data is transmitted to a main control device via sensing means such as temperature sensors, each having a memory means in which the ID code is stored, and via transmitting/receiving means such as switching elements. There is a stand-by period in the operation of the main control device after the main control device issues a command to start a sensing operation until the main control device issues a command to perform a read operation. The main control device receives power through a signal line the voltage of which is kept at a high level during the stand-by period. Thus, an equipment sensing system and an equipment control device which enable reliable and quick sensing, cost reduction, smooth control, and simplified wiring are provided.
