  • Gas fuel supply system for vehicle
    Patent number: 5632250
    Abstract: Supply of fuel is stopped when fuel pressure sensed by a pressure sensor provided upstream of a regulator is at a predetermined value or less to avoid abnormal combustion caused by improper adjustment of air/fuel ratio. Even slight variation of the fuel pressure is sensed by monitoring the fuel pressure in an interval after closing a fuel shut-off valve once opened to re-opening of it. In addition, an abnormal state in the fuel system is detected by comparing an accumulated value of amount of injected fuel and an estimated value of fuel consumption in the tank. Furthermore, the peak current value of the fuel injection valve is controlled so that, when the engine at a low temperature is started, lift load of the injection valve is larger than sticking force of the injection valve, thereby preventing such situation where the injection valve is frozen so that it cannot supply fuel to the engine. In this case, the engine can be smoothly started by simultaneously controlling the valve open time.

  • Method for drying erythritol crystals
    Patent number: 5202507
    Abstract: A method for drying erythritol crystals having a moisture content of from 1 to 10% by weight to reduce to the moisture content of 0.15% by weight or below, which comprises drying under fluidized state wherein a temperature of a gas to be used in the fluidized drying is controlled within a range of from 10.degree. to 60.degree. C. at least until the moisture content of said crystals is reduced to 0.5% by weight or below.The moisture content of erythritol crystals (moisture content: 1 to 10% by weight) can be highly efficiently reduced to 0.15% by weight or below in a stable form without deteriorating the crystalline properties and form by fluidized drying said erythritol crystals with the use of a gas flow of a relatively low specific temperature.

  • Catalyst for conversion of carbon monoxide
    Patent number: 4933313
    Abstract: A catalyst for conversion of carbon monoxide in water gas reaction, which comprises iron oxide, chromium oxide and magnesium oxide in the proportions of the from 40 to 85% by weight computed as Fe.sub.2 O.sub.3, from 12 to 45% by weight computed as Cr.sub.2 O.sub.3 and from 3 to 15% by weight computed as MgO, respectively.
