  • Voltage booster device having voltage-suppressing circuit
    Patent number: 7167040
    Abstract: A voltage booster device includes a booster circuit for boosting a power source voltage such as a battery voltage, a voltage-suppressing circuit for suppressing operation of the booster circuit when the boosted voltage reaches a predetermined voltage such as a Zener voltage of a Zener diode included in the voltage-suppressing circuit, and a control circuit having a microcomputer for supplying a voltage-boosting signal when the power source voltage is lower than a predetermined minimum voltage. When the power source voltage is lower than the minimum voltage, the power source voltage is boosted. When the boosted voltage reaches the predetermined voltage such as the Zener voltage, the level of the boosted voltage is kept constant at the level of the predetermined voltage.

  • Temperature control apparatus for injection molding machine
    Patent number: 6343920
    Abstract: A memory mounted on the same board as a temperature sense module stores a temperature correction value proper to this temperature sense module. On the basis of the temperature correction value read out of the memory, a temperature setting section controls power to a heater, thereby carrying out a temperature control of an injection molding machine.
