Filed: 2007-02-09
Abstract: <P>PROBLEM TO BE SOLVED: To perform appropriate pump torque control by preventing hunting from being caused by interference between speed sensing control at the low temperature of hydraulic oil and the control of the number of revolutions of a prime mover.  <P>SOLUTION: A regulator 31 controls displacement volumes of hydraulic pumps 2 and 3 so that the absorption torque of the hydraulic pumps 2 and 3 cannot exceed set maximum absorption torque.

Filed: 2007-02-16
Abstract: <P>PROBLEM TO BE SOLVED: To enable AD conversion in accurate timing even when a sampling rate of the AD conversion is a value close to a symbol rate of a received signal.  <P>SOLUTION: The optical receiver converts an optical signal from an optical transmitter which uses a modulation method in which an optical intensity waveform of each code is an RZ pulse into a digital signal by conversion processing at an AD (Analog to Digital) conversion part. At a control value calculating part subsequent to the AD conversion part, an absolute value of the digital signal, or a value in one-to-one correspondence to the absolute value of the digital signal is obtained by digitally processing the digital signal. Base on the absolute value of the digital signal, or the value in one-to-one correspondence to the absolute value of the digital signal, an error of sampling timing from optimal timing at the AD conversion part is estimated. Based on the error, a control value for controlling the sampling timing is calculated. Base on the control value, a phase of a pulse for defining the sampling timing of AD conversion can be corrected.  <P>COPYRIGHT: (C)2008,JPO&INPIT
