  • Patent number: 7800358
    Abstract: After the periphery of the magnetic sensitive element is surrounded by an elastic member, the magnetic sensitive element is mold-formed with resin material. Soft epoxy or gel resin is employed as the elastic member, poured in an element-mounting space and solidified. The magnetic sensitive element is surrounded by silicone rubber. Such construction allows the magnetic sensitive element not to be affected by vibration and allows the elastic member to absorb the stress which is created due to the thermal deformation of the molded resin.

  • Patent number: 7587938
    Abstract: A thermal gas-flow measuring instrument has a first heating resistor placed in the gas to be measured. A temperature sensing resistor is positioned upstream or downstream of the first heating resistor and generates signals relating to the flow rate. Between the first heating resistor and the support for supporting the first heating resistor is a second heating resistor that is electrically insulated from the first heating resistor. The second heating resistor suppresses the heat being transferred from the first heating resistor to the support. A control circuit controls the temperatures of the first heating resistor and the second heating resistor so that the operational temperature range of the second heating resistor or the temperature range at the joint section between the first heating resistor and the second heating resistor is at or above the temperature at which water droplets evaporate to disappear by film boiling.

  • Patent number: 5967128
    Abstract: According to the invention, a primary winding of an ignition coil is coupled with an insulated-gate bipolar transistor (IGBT). The IGBT is controlled by a current restriction circuit, which includes a control transistor for performing the on-off operation of the IGBT such that the IGBT is made conductive upon occurrence of an ignition control signal, and nonconductive, when a primary current of the ignition coil reaches a certain value depending on a reference voltage determined by a bias circuit. The bias circuit has a condenser, which is charged by a base current of the control transistor to change the base potential of the transistor slowly, when the transistor is made nonconductive.
