摘要:
A spacer of the present invention for use in an image display device, which has the spacer between a cathode substrate with a cold cathode electron emitting device formed thereon and an anode substrate with a phosphor formed thereon, comprises a phosphate glass having transition metal oxides as its main components, and a higher phosphate concentration layer at the spacer surface. A thickness of the higher phosphate concentration layer is suppressed to 0.5 μm or less. More preferably, the spacer has a water resistant conductive passivation layer formed on its surface. This suppresses the thickness of the higher phosphate concentration layer to a thinner level, so that the spacer is less likely to be charged thus reducing the deflection amount of electron beam. An image display device of the present invention using above spacer can apply a higher voltage to the anode substrate, thus increasing the image quality.

Thus, a distribution of magnetic properties serving as a pinning site of the movement of a magnetic wall in case of recording information to the magnetic layer 13 is formed in the magnetic layer 13.

The intake pressure and temperature of a Diesel engine equipped with a supercharger are sensed and the sensed intake pressure value is divided by the sensed intake temperature value to obtain an intake density. A value indicative of the intake density is divided by a value indicative of the air-excess ratio computed in accordance with the operating condition of the engine producing a smoke-limit injection amount. The smoke-limit injection amount is compared with the injection amount corresponding to a part-load condition of the engine and the smaller one of the values is applied to a linear solenoid for controlling the fuel injection amount adjusting member in the fuel injection pump of the engine.

A magnetic recording medium includes a non-magnetic substrate, an inorganic compound layer that is formed on the substrate and which contains a crystalline first oxide and a second oxide, and a magnetic layer that is formed on the inorganic compound layer. The crystalline first oxide comprises at least one oxide selected from cobalt oxide, chromium oxide, iron oxide and nickel oxide. The second oxide comprises at least one oxide selected from silicon oxide, aluminum oxide, titanium oxide, tantalum oxide and zinc oxide. The second oxide is present at a grain boundary of crystal grains of said first oxide. According to the present invention, magnetic recording media low in noise and diminished in thermal fluctuation and thermal decay can be obtained by making fine the crystal grains of a magnetic layer and controlling the dispersion of the grain size. Thus, magnetic recording apparatuses can be realized which can perform an ultrahigh density magnetic recording of higher than 20 Gb/in2.
摘要:
A function signal having a desired characteristic curve is generated through the logical operation on a vehicle speed signal indicative of the speed of a vehicle, a ratio signal indicative of the air-to-fuel of the mixture supplied to the engine mounted on the vehicle, and a pressure signal indicative of the pressure in the intake manifold of the engine. The position of an electromagnetic valve for adjusting the amount of fuel supplied to the engine is controlled in response to the function signal, thereby controlling the air-to-fuel of mixtures in accordance with the various driving conditions of the vehicle including the vehicle speed.
