  • Publication number: 20070099349
    Abstract: A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost therefor.

  • Patent number: 7068732
    Abstract: A receiving apparatus and a power control method that permit standby power consumption to be reduced. If a Digital Signal Processor (DSP) stores an Entitlement Management Message (EMM), which is contained in a MPEG transport stream (MPEG TS) packet, in a memory, the DSP supplies a startup signal to a human interface (HI) microcomputer. According to the startup signal from the DSP, the HI microcomputer supplies power to a back-end portion to start up a main microcomputer, which causes the main microcomputer to initiate processing.

  • Publication number: 20060057339
    Abstract: A treating liquid composition containing fine particles being so configured that their dispersion is kept or broken by an external factor such as contact between substance or ultraviolet irradiation, and a recording liquid composition containing a colorant being so configured that its dispersion or dissolution is kept or broken by the external factor are ejected separately onto a recording medium by ink-jet system. Droplets of the treating liquid composition and of the recording liquid composition are brought into contact with each other to cause a condition change such as a pH change or solubility change. The fine particles and the colorant aggregate separately without being substantially mixed with each other. This ink set produces a deep, colorful, sharp and glossy print in exact accordance with an original while effectively preventing feathering and color bleed on whichever of absorbable recording media and nonabsorbable recording media.
