Title: Prepaid-card system
Inventor: TAKEHANA HIDEAKI
IPC: G06K17/00
Filed: 1990-09-11
Abstract: PURPOSE:To prevent the unauthorized use of a prepaid card by rewriting the number-of-service data of the card to '0' immediately after the number-of- service data are read from the card and again rewriting the data to the remaining number-of-service data after the holder of the card completes the use of a TV receiver. CONSTITUTION:When a controlling section 18 discriminates that an inserted prepaid card is valid and the number-of-service data of the card is larger than the number-of-service data corresponding to unit watching time of a TV receiver 11, rewrite the number-of-service data of the card to '0'. Then the section 18 instructs a power supply controlling section 19 to make power supply to the receiver 11 so that the holder of the card can use the receiver 11. When the remaining number-of-service of the card becomes smaller than the unit watching time of the receiver 11, the section 18 writes the remaining number-of- service on the card. Therefore, the unauthorized use of the card can be prevented.

Title: Airtight equipment containing sf6 gas
Inventor: SATO SHIGEKATSU
IPC: H01F27/00
Filed: 1984-11-16
Abstract: PURPOSE:To surely detect the defect of airtight sealing even in case of small difference between internal and external pressures by installing the detector for oxygen or nitrogen on the top of the airtight equipment containing SF6 gas. CONSTITUTION:If SF6 gas 2 is sealed at 30 deg.C in the airtight SF6 gas container 1 with slightly higher pressure than the atmospheric pressure, the pressure of the gas 2 is nearly equal to the atmospheric pressure when the transformer is not operated, and becomes lower than the atmospheric pressure when the temperature is below 0 deg.C. If the sealing is broken in this state, the air 4 flows into the container 1 through the defect part. As the specific weight of the air is smaller than the one of SF6 gas, the air moves upward with time. The detector for oxygen or nitrogen installed on the top of the tank 8 detects oxygen or nitrogen in the air 4, so that the suitable measures can be performed and the serious accidents caused by the decrease of insulating strength, such as ground fault and short-circuit, can be prevented.
