Publication number: 20040103514Abstract: A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of-equipment and an installation space.Type: ApplicationFiled: November 24, 2003Publication date: June 3, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Yotsumoto, Yutaka Matsuda, Takayuki Gyoubu, Katsuya Sawada

Publication number: 20030167890Abstract: An impacting body is mounted rotatably to a spindle provided on a principal plane of a rotor. The impacting body is mounted so that a predetermined fitting gap is provided between the impacting body and the spindle and a part of periphery of the impacting body can be positioned beyond a periphery of the rotor. The rotor is rotated at a high speed to allow the impacting body to impact on an object to be processed at least at its critical impact velocity. This enables only the top layer of the object to be processed at the part on which the impacting body has impacted to be broken instantaneously. When the rotor is moved while being rotated, the object to be processed can be cut. According to this cutting device, an object formed of a single member such as glass, ceramics, resin, metal, or the like, or a composite member thereof can be cut continuously with one kind of cutting tool.Type: ApplicationFiled: April 7, 2003Publication date: September 11, 2003Applicant: Matsushita Electric Industrial Co., Ltd.Inventor: Yutaka Matsuda
