  • Publication number: 20070124016
    Abstract: The present invention provides a tool information display device for a processing machine which can display information on tools installed in appropriate parts of the processing machine, in an easy-to-understand manner. The present invention allows even the identification numbers of installed tools to be checked in an easy-to-understand manner. The present invention provides a tool information display device for a processing machine 101 having tool magazines 5, 6 on each of which a plurality of tools can be installed. The tool information display device includes tool information managing means 33 for managing information on the tools 7 installed on the tool magazines 5, 6. The tool information display device also includes installation status display means 33 for providing a display 50 of installation status of the tools which reproduces installation and arrangement of the tools on the tool magazine 5, 6 in a pseudo manner, in accordance with the information managed by the tool information managing means 33.

  • Patent number: 7077092
    Abstract: An engine starter includes a starter motor which has an armature, a series-wound field coil and a parallel-wound field coil and a short-circuiting unit for short-circuiting the series-wound field coil under a predetermined engine starting condition. The series-wound field coil has a suitable current limiting resistance. The short-circuiting unit short-circuits the series-wound field coil after a crankshaft of an engine passes a first top dead center of an engine.

  • Publication number: 20060142115
    Abstract: For regenerative generation at deceleration of a vehicle, a regenerative control apparatus for vehicles equipped with a lock-up clutch comprises a control unit for controlling rotary electric machine and the lock-up clutch. When the clutch is in a complete disengagement state or a slipping state at deceleration, the control unit controls the rotary electric machine to execute regenerative generation at a partial generation level lower than a regenerative generation level in a complete engagement state. When the clutch is in a complete engagement state at regenerative generation, the control unit controls the clutch so that the coupling state is transferred to a slipping state or a complete disengagement state when the number of revolutions having correlation to engine speed becomes lower than a predetermined threshold. Thus, recovering efficiency of the regenerative braking energy can be enhanced, while suppressing engine stall due to drastic increase of engine load torque.

  • Publication number: 20060122737
    Abstract: A power control apparatus acquires a maximum supply amount of power, transient maximum supply amount of power, and transient minimum supply amount of power of each power supply source. The apparatus further acquires a power cost of respective power supply sources, a load-required power and a charge request power. The apparatus acquires a combination of power supply sources that minimizes specific fuel consumption and determines an allocation amount of power. Taking transient response of respective power supply sources into account, the allocation amount of power of each power supply sources is corrected to be greater than a transient minimum supply power and smaller than a transient maximum supply power.

  • Publication number: 20060097577
    Abstract: A main power source (2) is, for example, an ordinary Pb battery and generates a voltage of 12-13 V. At the time of starting an engine, the main power source (2) supplies power to a starter (8a). The main power source (2) is given a higher priority than an auxiliary power source (3) to supply power to ordinary loads (8b). The auxiliary power source (3) is a high performance battery (e.g., Li ion battery), which has superior charge acceptance capability and better state detectability over the main power source (2). Furthermore, the auxiliary power source (3) has an internal resistance per unit capacity, which is smaller than that of the main power source (2), and generates a voltage of 9-12 V. A generator (1) is directly connected to the auxiliary power source (3). The auxiliary power source (3) stores regenerative power, which is generated by the generator (1) at the time of deceleration of a vehicle, and is used as a redundant power source for the main power source (2).

  • Publication number: 20060058897
    Abstract: An on-vehicle power supplying apparatus comprises a first battery charged by a generator driven by an on-vehicle engine, a second battery connected to an on-vehicle electric load, and a power adjuster adjusting power to be supplied from both of the first and second batteries to the electric load. For adjusting the power, he power adjuster uses a predetermined order in which the first battery is firstly made to supply the power to the electric load, provided that a residual capacity of the first battery is higher than a predetermined threshold, before making both the first and second batteries supply the power to the electric load cooperatively.

  • Publication number: 20050212438
    Abstract: A vehicle power supply system has a first battery connected to a generator, a second battery connected to an electric load and a series regulator between the first battery and the second battery. A control unit controls an input voltage of the series regulator and the output voltage of the series regulator based on a temperature of the series regulator, an output voltage of the series regulator and a load amount of the electric load. The control unit specifically controls an input upper limit voltage value of the series regulator to change an allowable value of a voltage difference between input and output of the series regulator.
