A socket holding device includes a peg component, a holding component, a positioning component, and a spring component. The present composition is for diesel engines having a regenerative DPF and running on diesel fuel with <10 mass ppm sulfur, contains a base oil and additives including metal detergent, ashless dispersant, and phosphorus-based anti-wear agent, and satisfies the conditions of a sulfated ash content of 0. The shifter array includes a plurality of selector circuits arrayed in a number of stages for shifting bits of an input data word in accordance with control signals, the output of the last stage corresponding to a rearranged output data word. The tuning circuit compares the first and second voltage signals and tunes a bias current in the first and second control circuits, whereby the static phase offsets of the first and the second control circuits becomes zero when the adjusted signal is phase-aligned with the reference signal in the steady state.
