  • Patent number: 7907376
    Abstract: A load control device includes a control circuit and a protection circuit. The control circuit controls driving of an electric load. The protection circuit monitors a power supply voltage supplied to the control circuit and stops control of driving the load by the control circuit, when the power supply voltage drops below a threshold value. The protection circuit provides the threshold value with a hysteresis characteristic having a width determined by a product of a wiring resistance of a path for supplying a driving current to the load and a maximum value of the driving current.

  • Publication number: 20100026355
    Abstract: A load drive device for driving an inductive load by PWM controlling a switching element includes synchronization control unit, a synchronization signal input terminal, and a synchronization signal output terminal. The synchronization control unit outputs the PWM signal to the switching element. The synchronization control unit receives a synchronization signal through the input terminal from an exterior. The synchronization control unit outputs the synchronization signal through the output terminal to an exterior. When the synchronization control unit does not receive the synchronization signal, the synchronization control unit outputs the synchronization signal such that a first switching period of the PWM signal is prevented from overlapping with a second switching period of a PWM signal of an external device. When the synchronization control unit receives the synchronization signal, the synchronization control unit generates the PWM signal based on the synchronization signal.

  • Patent number: 7141627
    Abstract: An epoxy resin cured article has a high glass transition temperature and low dissipation factor. An epoxy resin composition from which the cured article can be having excellent solubility in solvents is used to produce the cured articles. A polyester as a curing agent of an epoxy resin composition having an aromatic polyhydroxy coumpound residue including an aryloxycarbonyl group at the molecule of the terminal, an aromatic polyvalent hydrocarbon group residue, and bulky structure, is used. Since the curing agent behaves as a polyfunctional curing agent, a cured article produced therefrom has a high crosslink density. Since highly polar hydroxyl groups are not formed during curing, a cured article has high glass transition temperature and a low dissipation factor. The cured article does not release low molecular weight carboxylic acids though hydrolysis of ester bonds at crosslinked bonds.

  • Publication number: 20060154303
    Abstract: In the case where many interactional substances are immobilized on the front surface side of a light transmitting plate capable of generating evanescent waves on the front surface, and where the fluorescence levels in the interactions between the interactional substances and a fluorescence labeled test substance are detected in a liquid layer according to a conventional method, the detection sensitivity and S/N ratio are low due to the background noise. Furthermore, it is necessary to perform a gel filtration purification step for the purpose of removing an excessive amount of the fluorescence dye used for labeling a test substance before the interactions between the fluorescence labeled test substance and the interactional substances are performed.

    Abstract: A load control apparatus, in the form of a hybrid IC, comprises a microcomputer, control IC, and a plurality of MOS transistors. The control IC comprises only one temperature detection circuit for the MOS transistors. The MOS transistors and the temperature detection circuit are closely provided in thermally coupled manner. A temperature detected by the temperature detection circuit is compared with a predetermined threshold temperature for the purpose of detecting abnormal heat generation. When abnormal heat generation is detected, a current of each MOS transistor detected by a current detection circuit is compared with a predetermined threshold current for the purpose of detecting the MOS transistors under abnormal condition. The MOS transistor which is under the abnormal condition is exclusively controlled to protect other components.
