Filed: 1990-04-28
Abstract: PURPOSE:To indicate a correct charging status by providing a first and a second light emitting diodes with a color different from each other and changing brightness of the first light emitting diode with the progress of the charging. CONSTITUTION:In a two-colored light emitting diode 7, brightness of a first light emitting diode 71 changes with the progress of the charging as compared with that of a second light emitting diode 72, and the ratio of luminescent color of the light emitting diodes 71 and 72 changes. If it is set so that brightness of the second light emitting diode 72 is initially higher than that of the first light emitting diode 71, two-colored light emitting diode 7 is initially green and, in the later charging period, brightness of the first light emitting diode 71 is higher than that of the second light emitting diode 72, the luminescent color changes to red through amber with the progress of the charging.

Title: Engine intake air amount control device
Inventor: EBINO HIROSHI
IPC: F02D41/00
Filed: 1986-05-19
Abstract: PURPOSE:To prevent an engine from stalling and abruptly increasing its rotational speed when a desired rotational speed is high, by appropriately regulating the intake-air amount during deceleration of the engine in accordance with the desired rotational speed of the engine during idle operation. CONSTITUTION:A control unit 15 receives signals from a water temperature sensor 18 and the like to set a desired rotational speed during idle operation, and sets a basic control value which meets a desired opening degree of a control valve 11 in accordance with the thus set desired rotational speed. During transition after the engine is decelerated to an idle rational speed, a transition correction value is set in accordance with the desired rotational speed, being set to be large if the desired rotational speed is low but to be small if the same is high, and therefore, the control valve 11 is driven in accordance with the basic control value together with the correction value added to the former. Accordingly, during deceleration until the feed-back control for the idle rotational speed is initiated, the intake-amount is increased to a value which is larger than that during idle operation, in accordance with the desired rotational speed, thereby it is possible to prevent the engine from stalling and abruptly increasing its rotational speed.
