But on IC card fuel dispenser,?0?due to employ temperature control device. Turn on the device when necessary. Apart from the above functions IC card fuel dispenser should be provided with these traits such as explosion-proof electric safety, anti-dust, anti-interference, high applicability of power supply, high reliability, low ratio of failure, convenient for combination and expansion. Article IV Fuel dispenser and reader working flow Refueling process Under normal situation, filling process should be like this: When power supply is connected, the whole system begins to initiate. As CPU get open command (nozzle has switched on) motor is startup; small flux solenoid valve switch on, oil flowing out of nozzle; CPU calculates volume filled according to pulse transmitted by sensor; at same time, large flux solenoid valve is open, being large filling state. Metering circuit counts paid volume and money on basis of pulse sign transmitted by flow sensor, then transmit these data and unit price into CPU that control the display of current filing. Metering CPU, if in randomly filing, will switch off solenoid valve and motor to end filing when receive stop sign (nozzle has switched off). If in presetting filing process, metering CPU will firstly close large flux solenoid valve when paid volume approaching to presett fuel dispenser ing volume (100ml~~300ml), small flux s fuel dispenser olenoid valve being open until paid volume is equivalent to presetting volume. Finally, current filing information such as filled volume, money and unit price (PPU) is transmitted into CPU and display on screen. The proportion of large flux to small flux is 10 to 1. The knowledge of f fuel dispenser uel dispenser’s normal working procedure is of importance to judge trouble and failure. Reader flow chart of main programme Diagram 3-27: Filling operation flow

    economy more like a sledgehammer than a scalpel. A modest rise in rates is unlikely to halt rising share prices, but an increase sufficient to pop the bubble would slow the whole economy and could even cause a recession. Mr Greenspan thus concludes that it is safer to wait for a bubble to burst by itself and then to ease monetary policy to soften a downturn. Consider each of these arguments in turn. First, the job of a central bank is not just to prevent inflation, but also to ensure financial stability. Yet the three biggest stockmarket bubbles in the past century—America s in the 1920s and 1990s and Japan s in the 1980s—all developed when inflation was low. Arguably, Mr Greenspan has defined the role of monetary policy too narrowly. Inflation is often described as too much money chasing too few goods. But in a world awash with cheap money and with potent new sources of supply, such as China, to hold prices down, inflation will remain low and so fail to signal if an economy is overheating. Increased central-bank credibility also helps to anchor inflation. If central banks hold interest rates low, this will encourage risk-taking in financial markets and excess liquidity will spill over into asset prices rather than traditional inflation (see chart 2). Asset-price inflation can be as harmful as conventional inflation. A sudden collapse in share or house prices can trigger a deep downturn. And surging asset prices also distort price signals and cause a misallocation of resources? by encouraging too litt fuel dispenser le saving, or too much investment in ho fuel dispenser using, so reducing future growth. This is why central banks need to pay closer attention to asset prices. Second, it is not, as Mr Greenspan argues, impossible to identify bubbles. When prices have lost touch with fundamentals and there are other signs of excess, such as rapid c fuel dispenser redit growth, alarm bells should ring. Mr Greenspan s “irrational exuberance?speech in December 1996 shows he was concerned about a bubble inflating long before the
