| 20090067119 | Separator for electrochemical device and method for producing the same, and electrochemical device and method for producing the same - An electrochemical device having excellent safety at a high temperature is provided by using a separator for an electrochemical device, which is made of a porous film including a first separator layer and a second separator layer. The first separator layer includes, as a main ingredient, at least one kind of resin selected from the group consisting of resin A that has a melting point in a range of 80° C. to 130° C., and resin B that absorbs a nonaqueous electrolyte and swells due to heating and whose swelling degree is increased as the temperature rises, the second separator layer includes, as a main ingredient, a filler that has a heat-resistant temperature of not lower than 150° C., and at least one of the first separator layer and the second separator layer includes flakes. | 03-12-2009 |
| 20090199552 | HYDRAULIC WORKING MACHINE - A hydraulic circuit for a hydraulic working machine is composed of a main pump | 08-13-2009 |
| 20090325058 | ELECTROCHEMICAL DEVICE AND METHOD FOR PRODUCTION THEREOF - An electrochemical device of the present invention includes a positive electrode, a negative electrode, a non-aqueous electrolyte, and a separator. The separator includes a first porous layer composed mainly of a thermoplastic resin and a second porous layer composed mainly of insulating particles with a heat-resistant temperature of 150° C. or higher. The first porous layer is disposed to face the negative electrode. | 12-31-2009 |
| 20100015530 | SEPARATOR FOR ELECTROCHEMICAL DEVICE, ELECTRODE FOR ELECTROCHEMICAL DEVICE, AND ELECTROCHEMICAL DEVICE - A separator for an electrochemical device of the present invention includes a porous film including: a filler; an organic binder; and at least one resin selected from resin A that has a melting point of 80 to 140° C. and resin B that absorbs a non-aqueous electrolyte and swells upon heating and whose swelling degree increases with increasing temperature, and the filler contains boehmite having a secondary particle structure in which primary particles are connected. | 01-21-2010 |
| 20110039145 | POROUS FILM FOR SEPARATOR, BATTERY SEPARATOR, BATTERY ELECTRODE, AND MANUFACTURING METHODS THEREFOR, AND LITHIUM SECONDARY BATTERY - The present invention provides a lithium secondary battery using a separator including a porous film formed by binding inorganic oxide particles together with a binder. The inorganic oxide particles are treated so that an amount of alkali metal elements eluted therefrom when they are immersed in ion exchange water is reduced to 1000 ppm or less. As a result, it is possible to provide a lithium secondary battery with a high degree of reliability, whose characteristics deteriorate less when it is used or stored for an extended period. | 02-17-2011 |

| 20100266458 | Construction Machine - Provided is a construction machine, which can suppress a rise in the temperature of a liquid reducing agent in a liquid reducing agent tank. The construction machine is provided, within an engine compartment | 10-21-2010 |
| 20110219757 | Muffler Draining Apparatus for Working Machine - A muffler draining apparatus for a working machine is provided which allows a drain line having excellent heat resistance to be reliably installed, even when a device or equipment is present at the position below a muffler. In a muffler draining apparatus that is provided to a muffler equipped to a hydraulic excavator, and includes a drain line that discharges water accumulated in the muffler to the outside of a vehicle body, the above-described drain line includes a single metal tubing whose one end is connected to the muffler, and whose intermediate portion provided continuous to the one end is extended into the space formed between the muffler and a hydraulic pump located below the muffler. The intermediate portion of the metal tubing includes a single linear portion and plural bent portions. Also, the muffler draining apparatus includes, for example, a single support bracket that is fixed to the muffler, and supports the intermediate portion of the metal tubing. | 09-15-2011 |
| 20120079810 | Exhaust Assembly for Construction Machine - Disclosed is an exhaust assembly for a construction machine having a revolving upperstructure and an engine mounted on the revolving upperstructure. The exhaust assembly is to be arranged inside the revolving upperstructure of the construction machine, and is provided with an after-treatment device for exhaust gas from the engine and an exhaust pipe for releasing exhaust gas, which has been guided from an outlet port of the after-treatment device, to an outside. The exhaust assembly includes a concave-convex part, which has plural concavities and convexities, is arranged on an inner wall of the exhaust pipe, and extends in a direction of discharge of the exhaust gas. | 04-05-2012 |
