Thermosetting low-dielectric resin composition and use thereof

The present invention relates to a thermosetting low dielectric resin composition, a laminate for use in printed wiring, a laminate for a circuit, and the like. The present invention's thermosetting low dielectric resin composition contains a specific siloxane denatured polyimide, a compound having two or more allyl or methylallyl groups, and a compound having two or more maleimide groups. This resin composition adheres extremely well to metals with a low dielectric constant and low dielectric dissipation factor, and demonstrates very little scattering of the resin during operational processes like punching or cutting. By using laminates or laminates for circuits that employ this resin composition, electrical signals can be propagated more quickly, enabling signals to be processed at faster speeds. In addition, the present invention can be applied to the formation of miniaturized circuit wiring, and is suitably employed in electronic devices employed in the high frequency region, and, in particular, in electronic devices that must be made smaller and lighter in weight.

Heat-resisting adhesive composition and adhesive tapes for electronic parts

A diesel engine has a fuel injection nozzle to which pressurized fuel is supplied from a pump. The nozzle has a pressure sensor detecting the fuel pressure and a lift sensor sensing a lift magnitude of a needle valve. An electronic control unit (ECU) computes a variation ratio of the fuel pressure value which is measured by the pressure sensor. The ECU computes a non-increasing point in an increasing part of variation ratio and judges the point to be a timing for starting the fuel injection of the nozzle. The EPU also computes the actual fuel injection amount in accordance with the fuel injection timing as well as the fuel pressure and the lift amount of the needle valve both at the various points. The EPU controls the actual injection amount to be identical to a target fuel injection amount.

A two-stroke engine comprising three exhaust valves and two intake valves. These exhaust valves and these intake valves are arranged on the peripheral portion of the inner wall of the cylinder head, and one additional intake valve is arranged on the central portion of the inner wall of the cylinder head. The valve openings of the three intake valves, which are located on the exhaust valves side, are masked by the masking walls. The central portion of the combustion chamber is scavenged by the fresh air fed from the additional intake valve, and the peripheral portion of the combustion chamber is scavenged by the fresh air fed from the remaining two intake valves.

Two-stroke engine

A two-stroke diesel engine comprising a pair of intake valves arranged on one side of the inner wall of the cylinder head, and a pair of exhaust valves arranged on the other side of the inner wall of the cylinder head. The valve openings of the intake valves, which are located on the exhaust valve side, are covered by corresponding masking walls. A prechamber is formed in the cylinder head, and the opening of the prechamber is arranged in the peripheral inner wall portion of the cylinder head, which is positioned farthest from the exhaust valves, between the intake valves.

A pilot injection device for a fuel injection pump has an accumulate piston movable in response to a fuel pressure from a pressurizing chamber of the fuel injection pump to cause a pilot injection prior to a main injection by the pump. The device is provided with a back-pressure chamber filled with fuel and having a volume variable by the movement of the accumulate piston. Air trapped in the back-pressure chamber can be removed therefrom through a hole to improve the operation characteristic of the pilot injection device.

Pilot injection device for fuel injection pump

A fuel injection control apparatus provided with an air blast valve having a nozzle opening connected to an engine-drive air pump through a compressed air passage, a fuel injector for injecting fuel in the compressed air passage, and an opening and closing valve for controlling the opening and closing of the nozzle opening. When the compressed air pressure in the compressed air passage is lower than a set pressure, fuel is injected from the fuel injector during the opening of the opening and closing valve and the injected fuel is ejected from the nozzle opening by inertia force. When the compressed air pressure in the compressed air passage is above a set pressure, the fuel is injected from the fuel injector during the closing of the opening and closing valve and the injected fuel is ejected from the nozzle opening by compressed air during the opening of the opening and closing valve.
