    Abstract: A voltage detection device includes: a plurality of voltage-detecting ICs installed in order to detect voltages of a plurality of blocks of a secondary battery, each of the voltage-detecting ICs being installed for each of the blocks; and an interruption control unit that controls interruption operations of the voltage-detecting ICs. After resetting all of the voltage-detecting ICs by transmitting a trigger signal to all of the voltage detecting ICs, the interruption control unit transmits a control signal in which an address of a voltage-detecting IC allowed to execute an interruption operation is designated. Each of the voltage-detecting ICs receives the control signal within a designated time set in advance, executes the interruption operation when an address of its own is designated, and is left reset when the address of its own is not designated.

  • Publication number: 20150296667
    Abstract: Component parts are mounted on a top surface of a ceramic substrate having therein a ground line including a ground layer electrically connected to a grounding portion exposed on a bottom surface of the ceramic substrate. Then, the top surface of the ceramic substrate is coated with a mold resin layer. Half-cut is performed on the ceramic substrate from the surface of the mold resin layer to expose a portion of the ground line from a side surface of the ceramic substrate. A conductive shield film is so formed to cover the surface of the mold resin layer and the exposed portion of the ground line by the half-cut. A slit for dividing the ceramic substrate into individual electronic components is formed before the dividing the ceramic substrate.

  • Patent number: 9128163
    Abstract: In a voltage measuring apparatus for a plural battery according to the present invention, each of voltage detecting ICs (21-1) to (21-5) connects a switch SW1 to a reference voltage generator 24 and supplies a reference voltage Vf from the reference voltage generator 24 to an A/D converter 26. The A/D converter 26 digitizes the reference voltage Vf, which is transmitted to a main microcomputer 33. The main microcomputer 33 finds a theoretical value of the reference voltage according to an ambient temperature, compares the theoretical value with the measured value of the reference voltage Vf, and determines whether or not the voltage detecting accuracy of the first voltage detecting IC (21-1) is good.

  • Publication number: 20150090546
    Abstract: A steering damper is configured to adjust a damping force of a rotor covered by a lower casing and an upper casing by changing the viscosity of a magnetic fluid with an electromagnet. Since a magnetic fluid chamber is provided with a volume compensating unit, even when the volume of the magnetic fluid expands, or air entrainment occurs, air bubbles lighter than the magnetic fluid are collected in the volume compensating unit. Thus, characteristic variations of the steering damper due to volume expansion or air entrainment of the magnetic fluid are prevented.

  • Patent number: 8874349
    Abstract: A sensor control apparatus including a gas sensor having a sensor element, a housing and a base part formed of a resin. The apparatus includes a heating part and a control part. When the control part determines that a predetermined automatic stop condition has been satisfied, the control part switches from a control for maintaining the temperature of the sensor element at an activating temperature to a control in a stop state for reducing at least one of voltage and current supplied to the heating part so as to set a temperature of the base part to a value equal to or lower than a shape holding temperature of the resin. Also disclosed is a sensor control method for holding a temperature of a sensor element to an activating temperature.

  • Patent number: 8801283
    Abstract: A circuit body includes a flexible insulation sheet with an electric circuit pattern having wiring patterns and a temperature sensor arranged in the electric circuit pattern. The electric circuit pattern has a temperature-sensor connecting portion and a heat-concentrating pattern formed integrally with the temperature-sensor connecting portion so as to have a larger width than that of the wiring pattern. The temperature sensor is touched through the heat-concentrating pattern to an object to be measured. The wiring patterns and the heat-concentrating pattern are formed integrally on a primary surface of the insulation sheet by printing. An additional heat-concentrating pattern is further formed on a secondary surface of the insulation sheet at a position corresponding to the temperature-sensor connecting portion. The heat-concentrating patterns are bent integrally with the insulation sheet and touched to the object to be measured.
