  • Patent number: 9309123
    Abstract: This invention provides a method for forming a catalyst layer for carbon nanostructure growth, which can eliminate the influence of water in a liquid for catalyst layer formation, can grow homogeneous and highly oriented carbon nanostructures over the whole area of a substrate and can realize mass production of the carbon nanostructures, and a liquid for catalyst layer formation for use in the method, and a process for producing carbon nanostructures using the catalyst layer formed by the method. The catalyst layer for use in the production of CNTs is formed by preparing a catalyst metal salt solution of a catalyst metal-containing metal compound (a catalyst metal salt) dispersed or dissolved in a solvent having an ample wettability towards the substrate and coating the catalyst metal salt solution onto the substrate to a form a thin film. The thin film is then heat treated to form a catalyst layer.

  • Patent number: 6661108
    Abstract: In a hybrid drive device which drives an electrical motor with electrical power from a storage device and/or from a generator driven by an engine, a secondary battery is generally used as the storage device. However, the storage device must be replaced at fixed intervals due to a short battery life. In addition, the low charging/discharging efficiency of a secondary battery limits improvements in fuel economy of the drive device. The present invention avoids these shortcomings by providing a storage device that includes a condenser bank with a plurality of condenser cells connected in series, parallel monitors which are connected in parallel to each condenser cell and which bypasses the charging current when the respective terminal voltages exceed a fixed value, and a switching converter with fixed current output characteristics which controls the charging electrical power to the condenser bank.

  • Patent number: 5248189
    Abstract: A valve mechanism is provided in a hydraulic line which connects a master cylinder of a brake system and a brake provided for a driving wheel of a vehicle. When the slip of the driving wheel is larger than a predetermined value, the valve mechanism is selectively moved between a position where it directly applies brake fluid from the master cylinder to the brake and a position where it returns brake fluid discharged from the brake to an oil reservoir, thereby controlling the driving torque of the driving wheel to converge the slip of the driving wheels to a proper level. An oil pump is operated to return the brake fluid in the oil reservoir to the master cylinder when the valve mechanism is operated to effect the slip control. While the brake pedal is in the released state, the oil pump is kept operated during the slip control and for a predetermined time after interruption of the slip control so that the brake fluid in the oil reservoir is returned to the master cylinder substantially completely.
