摘要:
On a credit IC card, issuing by a credit card company, brought by a credit payer with him/her is stored at least personal information for identifying a credit card company, a card number and a credit payer. Based on input of a code number by the credit payer and the stored information read out from the credit IC card, a cellular telephone is used to automatically inquire of an information center of the credit card company whether the credit can be gained. This can therefore eliminates complication involved by payment using the credit IC card and ensures smooth use of the credit IC card, with the cost performance being increased to spread the expensive credit IC card.

The present invention relates to a dry vacuum pump unit capable of achieving ultimate pressure of about 1 Pa. The vacuum pump unit includes a main pump (15) disposed at an outside-pressure side, and a booster pump (16) disposed at a vacuum side. The booster pump (16) and the main pump (15) are coupled in series. The booster pump (16) has a higher pumping speed than that of the main pump (15). Each of the main pump (15) and the booster pump (16) includes a pair of pump rotors (52a and 52b), a casing (50) having an inlet port and an outlet port, and a pair of magnet rotors (54 and 54) rotatable with the pair of pump rotors.

摘要:
A fire engine or a truck carrying a fire extinguishing system having a device for supplying a powder fire extinguishing agent coated with a waterproof film, e.g., a silicone resin, and a fire-fighting water delivery pipeline, is used. The powder fire extinguishing agent is added and mixed into the fire-fighting water delivery pipeline, and mixed water is delivered through a fire house and discharged from a spray nozzle provided at the distal end of the fire hose.
