A crank angle detecting device that is independent of fluctuations in engine rotational speed and reliably detects a reference crank angle position. A ring gear fixed to a crankshaft of a single cylinder engine has plural projections (teeth) formed around its outer periphery at equal intervals and one irregular interval portion (toothless portion). A crank angle sensor detects start and end on both sides of each projection, a lateral length of each projection and an interval of two adjacent projections, and calculates a ratio therebetween to distinguish the irregular interval portion from the projections. The crank angle sensor and the irregular interval portion are so positioned that the irregular interval portion is detected when the piston is close to bottom dead center.

To provide an acceleration control method for an engine, which determines the accelerating state appropriately without a sensor, a mechanism, or the like specially added for determining the accelerating state and performs suitable acceleration control, while it prevents acceleration misdetermination at engine start or at an extremely low engine speed to improve engine startability and drivability at an extremely low engine speed.An acceleration control method for a four-stroke engine, in which a pulse is generated for every predetermined crank angle for detecting a crank angle of the engine, a transient state of the engine is determined by detecting the pulse and by detecting the intake air pressure in the intake passage on a downstream side of a throttle valve of the engine, and the acceleration control is performed according to the state of the engine, is characterized in that the acceleration control is prohibited on condition that the engine state is at engine start or at an extremely low engine speed, and in that the acceleration control is allowed otherwise.
摘要:
A vessel speed indicating device including a semiconductor pressure detector that detects dynamic pressure and outputs a signal indicative of this pressure. A speed indicator and calculator is incorporated which senses when the speed is below a speed at which high accuracy can be expected and outputs a warning signal in the event of that condition. Alternatively, when the device is operating in a range where the speed signal is accurate, actual speed is indicated.

A plurality of conductive pads (2) are formed on a mounting surface of a mounting board. Conductive pads (11) are formed on a principal surface of a semiconductor chip (10) at positions corresponding to the conductive pads of the mounting board, when the principal surface faces toward the mounting board. A plurality of conductive nanotubes (12) extend from the conductive pads of one of the mounting board and the semiconductor chip. A press mechanism (3) presses the semiconductor chip against the mounting board and restricts a position of the semiconductor chip on the mounting surface to mount the semiconductor chip on the mounting board, in a state that tips of the conductive nanotubes are in contact with the corresponding conductive pads not formed with the conductive nanotubes.
