  The quasi-Hilda comets (QHCs), being in unstable 3:2 Jovian mean motion
resonance, are considered a major cause of temporary satellite capture (TSC) by
Jupiter. Though the QHCs may be escaped Hilda asteroids, their origin and
nature have not yet been studied in sufficient detail. Of particular interest
are long TSCs/orbiters. Orbiters -- in which at least one full revolution about
the planet is completed -- are rare astronomical events; only four have been
known to occur in the last several decades. Every case has been associated with
a QHC: 82P/Gehrels 3; 111P/Helin-Roman-Crockett; P/1996 R2 (Lagerkvist); and
the possibly QHC-derived D/1993 F2 (Shoemaker-Levy 9, SL9). We focus on long
TSC/orbiter events involving QHCs and Jupiter. Thus we survey the known QHCs,
searching for further long TSCs/orbiters over the past century. First, we
confirmed the long TSC/orbiter events of 82P, 111P, and 1996 R2 in order to
test our method against previous work, applying a general N-body Newtonian
code. We then used the same procedure to survey the remaining known QHCs and
search for long TSC/orbiter events. We newly identified another long
TSC/orbiter: 147P/Kushida-Muramatsu from 1949 May 14 (+97days/-106 days)--1961
July 15. Our result is verified by integrations of 243 cloned orbits which take
account of the present orbital uncertainty of this comet. This is the third
long TSC and the fifth orbiter to be found, thus long TSC/orbiter events
involving Jupiter have occurred once per decade. Two full revolutions about
Jupiter were completed and the capture duration was 12.17 (+0.29/-0.27) years;
both these numbers rank 147P as third among long TSC/orbiter events, behind SL9
and 111P. This study also confirms the importance of the QHC region as a
dynamical route into and out of Jovian TSC, via the Hill's sphere.
