Title: Knocking control device for engine
Inventor: KAMADO KOICHI
IPC: F02D45/00
Filed: 1990-03-07
Abstract: PURPOSE:To improve the control accuracy by estimating the knocking strength larger as the rising time of the knock signal is smaller than the lowering time thereof, and restricting the knocking when the estimated knocking strength is larger than the predetermined value. CONSTITUTION:The rising time of the knock signal to be output from a knock sensor of an engine is detected by a rising time detecting means and the lowering time thereof is detected by a lowering time detecting means respectively. As the rising time is smaller than the lowering time, the knocking strength is estimated lower by a knocking strength estimating means. When this estimated knocking strength is larger than the predetermined value, a control means controls the engine so as to restrict the knocking. Since dispersion of the knock signal to be caused by a difference of the characteristics of the knock sensor, the engine and or the like is adsorbed, the knocking strength can be estimated accurately.

Abstract: PURPOSE:To make a film thickness and a film quality uniform even when an electrode plate is made large-sized. CONSTITUTION:Electric power is supplied to a cathode electrode plate 2 from its peripheral part via an electric-power introduction part which is composed of a protrusion 5 and of one part of a lower-side case body 4b.

The concentration of a power density in the central part of the cathode electrode plate 2 is hard to cause, and the power density is dispersed. In addition, electricity is conducted to the cathode electrode plate 2 from its peripheral part. As a result, when the electricity is conducted to, e.g. two parts out of the peripheral part, a conductor resistance at the cathode electrode plate 2 is set to a state that a resistance from one part of the peripheral part up to the central part is connected in parallel with a resistance from the other part of the peripheral part up to the central part, and becomes smaller than that in conventional cases.
