摘要:
A dynamic amount detector (12) generates correction information according to a predetermined relational expression, based on directions and magnitudes of dynamic amounts which are opposite to each other and imparted to one of directions of a plurality of detection axes, directions and magnitudes of dynamic amounts imparted to respective directions of the remaining detection axes, and detection values in a dynamic amount detecting means obtained when these dynamic amounts are respectively imparted. By means of this correction information, the output value detected by the dynamic amount detecting means is corrected. While a high detection accuracy is attained, the correction information concerning detection accuracy can be determined simply.

摘要:
A charge control system for an internal combustion engine which is capable of suppressing electromagnetic noise due to a control signal to a generator and of preventing an over-charge to a battery even if an input terminal receiving the control signal is grounded. The charge control system is composed of a generator (1) driven by an engine of a motor vehicle and a battery (4) charged with the output of the generator (1). Also included in the system is a computer unit (2) comprising a microcomputer CPU for calculating a target voltage Vreg on the basis of the operational states of the motor vehicle to compare a battery voltage Vb with the calculated target voltage Vreg so as to output a drive signal in accordance with the comparison result. This drive signal operates a transistor (Tr), incorporated into the generator, to control a field current If of the generator (1) so that the quantity of the power generation of the generator (1) increases and decreases to control the quantity of the charge to the battery (4).

The invention provides an optical fiber amplifier which assures stable operation of a pump light source and efficiently makes use of residual pump power to achieve improvement in conversion efficiency. The optical fiber amplifier includes a rare earth doped fiber (1). Pump light from a pump light source (2) is introduced into one end of the rare earth doped fiber (1) by way of a first optical coupler (3-1), and residual pump light originating from the pump light and arriving at the other end of the rare earth doped fiber (1) is demultiplexed by a second optical coupler (3-2) and then reflected by a reflecting mirror (4) so that it is introduced back into the rare earth doped fiber (1) or applied to the loss compensation of a dispersion compensating fiber by Raman amplification. The residual pump light introduced into the rare earth doped fiber (1) is intercepted, after passing the rare earth doped fiber (1), by an optical isolator (5) so as to prevent unstable operation of the pump light source (2) which may otherwise be caused by the residual pump light admitted into the pump light source (2).
