`Reply to OA dated July 12, 2011
`
`REMARKS
`
`Claims 1-4 are amended in order to more particularly point out, and distinctly claim the
`
`subject matter which the Applicant regards as the invention. The Applicant respectfully submits
`
`that no new matter has been added.
`
`It is believed that this Amendment is fully responsive to the
`
`Office Action dated July 12, 2011.
`
`Claims 1 and 2 stand rejected under 35 U.S.C. 103(a) as being unpatentable over
`
`Yoshio (JP-5340619) in view of Kawahara et a1. (U.S. Patent Application Publication No.
`
`2005/0103029) Reconsideration and removal of this rejection are respectfully requested in view
`
`of the present claim amendments and the following remarks.
`
`Claims 3 and 4 stand rejected under 35 U.S.C. 103(a) as being unpatentable over Yoshio
`
`in view of Kawahara et a1 and further in View of Park (U.S. Patent Application Publication No.
`
`2002/0162353). Reconsideration and removal of this rejection are respectfully requested in View
`
`of the present claim amendments and the following remarks.
`
`In the present invention, as shown in Fig. 6, the claimed pressure reducing unit (66), in
`
`parallel with a check valve (67), are connected to the expansion tank (65) at one end and
`
`connected to the suction side (208) of the compressor (20) at the other end. The discharge side
`
`(20D) of the compressor (20) is n_0_t connected to the expansion tank (65).
`
`In the refrigeration apparatus of Yoshio, as shown in Fig. 1, a pressure reducing unit (28)
`
`in parallel with a check valve (29) are connected to an expansion tank (26) at one end and to the
`
`low pressure side (24b) of the compressor (19) at the other end. However, the expansion tank
`
`
`
`US. Patent Application Serial No.: 12/300,703
`Reply to 0A dated July 12, 2011
`
`(26) is alfl connected to the high pressure side (24a) of the compressor (19).
`
`It is respectfully
`
`submitted that the arrangement of Yoshio would result in the refrigeration system of Yoshio
`
`operating in a different manner than the present claimed refrigeration system.
`
`Further, in regard to the invention of Claims 3 and 4, many capillary tubes (pressure
`
`reducing units), etc. are connected in the refrigerant circuit (low-temperature side refrigerant in
`
`Claim 4). Therefore, the flowing resistance becomes high and the length of the circuit becomes
`
`long.
`
`Thus, compared with the refrigerant circuit having one expansion valve as in Yoshio, the
`
`pressure in the high pressure side of the circuit cannot go down rapidly when the compressor is
`
`stopped in the circuit of Claims 3 and 4 of the present invention.
`
`Thus, when the compressor restarts,
`
`the load will be high if the tank, the pressure
`
`reducing unit, and the check valve are not connected as defined in Claims 3 and 4.
`
`In View of the amendments to Claims 1-4, and the above remarks, removal of the above
`
`rejections is respectfully requested.

`Reply to OA dated July 12, 2011
`
`In view of the aforementioned amendments and accompanying remarks, Claims 1-4, as
`
`amended, are believed to be patentable and in condition for allowance, which action, at an early
`
`date, is requested.
`
`If, for any reason, it is felt that this application is not now in condition for allowance, the
`
`Examiner is requested to contact the Applicant's undersigned Agent at the telephone number
`
`indicated below to arrange for an interview to expedite the disposition of this case.
`
`In the event that this paper is not timely filed, the Applicant respectfully petitions for an
`
`appropriate extension of time. Please charge any fees for such an extension of time and any
`
`other fees which may be due with respect to this paper, to Deposit Account No. 01-2340.
