  • Process for producing unstretched film, process for producing resin-coated metal sheet, and apparatus for producing unstretched film
    Patent number: 7985315
    Abstract: A process by which many kinds of unstretched films comprising a thermoplastic resin are produced each in a small amount and high yield. A thermoplastic resin (A) to be formed into an unstretched film and another thermoplastic resin (B) are separately melted by heating. The thermoplastic resin (B) is introduced to each edge part of a T-die (2) for extrusion. The two resins are ejected and extruded on a casting roll so that the thermoplastic rosin (B) is disposed on the side of each edge of the thermally melted thermoplastic resin (A). Thus, an unstretched film (20) is formed which comprises the thermoplastic resin (A) and the thermoplastic resin (B) disposed on the side of each edge of the resin (A). Thereafter, the parts constituted of the thermoplastic resin (B) are removed y cutting to form a target unstretched film (20) consisting only of the thermoplastic resin (A).

  • Semiconductor device
    Patent number: 7986216
    Abstract: In a case where an ASK method is used for a communication method between a semiconductor device and a reader/writer, the amplitude of a radio signal is changed by data transmitted from the semiconductor device to the reader/writer when data is not transmitted from the reader/writer to the semiconductor device. Therefore, in some cases, the semiconductor device mistakes data transmitted from the semiconductor device itself for data transmitted from the reader/writer to the semiconductor device. The semiconductor device includes an antenna circuit, a transmission circuit, a reception circuit, and an arithmetic processing circuit. The antenna circuit transmits and receives a radio signal. The transmission circuit outputs to the reception circuit a signal showing whether or not the antenna circuit is transmitting the radio signal.

  • Multimodal explosive
    Patent number: 7985308
    Abstract: A multimodal explosive, in particular for blast charges, which has, for increasing the power, a powder additive which is formed by a hydrogen-terminated monocrystalline silicon powder of at least one grain size range, which powder has the advantage that no oxidation phenomenon takes place even over many years—even at storage in ambient air. Due to the non-oxidized crystal surfaces, advantageously an immediate joint reaction with the explosive takes place in the detonation front and also extends into the post-reaction period with increasing crystal sizes, so that a different propellant effect is achieved depending on the additive.

  • Hydrodynamic machine
    Patent number: 7984610
    Abstract: The present invention relates to a hydrodynamic machine, especially a hydrodynamic retarder, including a bladed primary wheel and a bladed secondary wheel which are arranged opposite of each other axially with respect to their blade configurations such that they jointly form a working chamber. The working chamber can be filled with a working medium for one operating state in order to transmit torque from the primary wheel to the secondary wheel by means of a circulatory flow of the working medium. The working chamber can be emptied of the working medium for a non-operating state in order to prevent a transmission of torque from the primary wheel to the secondary wheel. A suction apparatus is connected with a fluidic connection to the working chamber in order to suck off working medium and/or air from the working chamber for forming a negative pressure in the working chamber in the non-operating state.
