摘要:
A disc music box for playing a melody, which comprises a disc (3) having a plurality of engaging parts (4, 40), a motor (M) for rotating the disc, and star wheels (12) guided and rotated by the engaging parts of the rotating disc for plucking music box petals (17a), wherein control information for controlling other instruments to be operated in association with the play of the music box is recorded at desired portions on the disc excepting portions where the engaging parts are disposed on the disc. An information disc (101) has both playing and control information and is driven to rotate at a predetermined speed. A tricky timepiece comprises a disc music box instrument (120) to which a music box disc (101) is attached and a tricky device (150) interconnected with the disc music box instrument to move puppets (151), thereby providing tricky performance. The term "tricky" is defined as mechanized movements designed to amuse or impress.

A fuel injector with an integrated spark plug for a direct injection type engine capable of adequate fuel injection and adequate spark discharge, even if it becomes very hot because the end part of device is exposed in a combustion chamber and a spark discharge is induced there. An electric conductor is disposed along the central axis, and the electric conductor is electrically coupled with a cable for supplying electric current for the spark discharge. A needle valve made of conductive material is electrically coupled with the electric conductor through a return spring made of conductive material and is reciprocally moved by a solenoid. A needle housing made of conductive material receives the needle valve and has a nozzle for injecting fuel and a center electrode at its end. A grounding electrode is disposed near the center electrode. Insulators are disposed outside of the electric conductor. Out side of the insulators, an outer cylinder is disposed, which is composed of inner wall which adheres to the insulators and outer wall which is placed outside of the inner wall at a uniform clearance which is used as a fuel passage. A connector assembly for connecting a fuel line and an electric cable for supplying electric current to the solenoid is attached to the outer cylinder.

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 judge 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 control the actual injection amount to be identical to a target fuel injection amount.
摘要:
A method and apparatus for automatically selecting process information for a plurality of image parts, in which a CPU, in an automatic reproduction process routine, determines a positional relation between two image parts in a page image based on figure vector data corresponding to the two image parts (S110). A rule including data such as vertical relative positions, types, and colors of the two image parts as a condition part and process information as an action part is previously stored as rule base RB in an external hard disk unit. When the two image parts are in a non-separate relation, the CPU reads attribute data of the two image parts in the non-separate relation (S150), and determines final process information by exchanging the attribute data with rule base RB (S190 and S200). The results of the processing including the final process information are then stored as a process information table TBL3.
摘要:
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.

An internal combustion engine having an air blast valve which injects fuel together with pressurized air in the form of a conical shaped spray of fuel. A depression is formed on the top face of the piston, and the conical shaped spray of fuel is injected from the air blast valve toward the depression. The longitudinal width of the depression in the moving direction of the spray of fuel is larger than the transverse width of the depression in the direction perpendicular to the moving direction of the spray of fuel, and the opposing side walls of the depression, which define the transverse width of the depression, are positioned slightly outward from the side face of the conical shaped spray of fuel.

A diesel engine comprising a plurality of cylinders each having a precombustion chamber and a fuel injector. A first camshaft for driving intake valves and a second camshaft for driving exhaust valves are arranged on the cylinder head and extended in parallel to the longitudinal axis of the engine body. Each precombustion chamber and each fuel injector is arranged centrally between the first camshaft and the second camshaft.

A two stroke engine equipped with a mechanically driven supercharger in the intake passage downstream of throttle valve. A bypass air passage bypassing the supercharger is provided, and a bypass air control valve is arranged in the bypass air passage. When the engine is idling, the bypass air control valve is controlled so that the level of vacuum in the intake passage between the throttle valve and the supercharger is maintained at a constant value.
