摘要:
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.
摘要:
A temperature recorder capable of storing, in time sequence, measured temperatures and measured times as temperature records in a memory incorporated therein, wherein, the temperature recorder is installed in a power line for temperature recording and, when the power line supplies a power in a normal temperature range, wirelessly transmits the temperature record to a monitor at a frequency of once every half day and, when an abnormal heating is detected from the power line, wirelessly transmits the temperature record as a temperature alarm record.
摘要:
A process for the preparation of 1,2-benzisoxazole-3-methanesulfonamide without isolation of intermediates in solid form, by using 4-hydroxycoumarin as a starting compound, and water and 1,2-dichloroethane as solvents; and an industrially useful process for the preparation of 1,2-benzisoxazole-3-acetic acid, by reacting 4-hydroxycoumarin and hydroxylamine in water.
摘要:
A temperature monitor includes a temperature sensor, a transmitter, and a controller. The temperature sensor generates a temperature signal based upon a detected temperature and the controller controls the temperature sensor to generate the temperature signal and controls the transmitter to transmit the temperature signal along with a time at a first predetermined interval.

A process for the preparation of 1,2-benzisoxazole-3-methane-sulfonamide without isolation of intermediates in solid form, by using 4-hydroxycoumarin as a starting compound, and water and 1,2-dichloro-ethane as solvents; and an industrially useful process for the preparation of 1,2-benzisoxazole-3-acetic acid, by reacting 4-hydroxycoumarin and hydroxylamine in water.
摘要:
Temperature measurement data obtained by measuring the temperature of a cable clamp (31) by a temperature sensor (320) is radio-transmitted from a temperature sensing unit (32) at a predetermined timing, and the radio-transmitted temperature measurement data is received by a receiving station (5), classified by the temperature sensing unit number, and stored in a temperature measurement data storage area (502A). The temperature measurement data transmitted from twelve temperature sensing units (32) can be received by one receiving station (5).
