  • Patent number: 7675426
    Abstract: A light guide part (20) is provided along a Z-axis on a side surface of a case (2) of a relay (1). The light guide part is a thick portion formed of a material forming the side surface of the case, and is structurally integral with the other parts of the case. Also, a light emitting device which emits light in response to application of a voltage to coil terminals (41) is provided within the relay (1) (case). A reflection surface (201) which reflects illuminating light emitted from the light emitting device in a (+Y) direction in a (+Z) direction is placed at a lower end of the light guide part. Illuminating light reflected by the reflection surface is guided to a display surface (200) placed at an upper end of the light guide part, to illuminate the display surface.

  • Patent number: 6545575
    Abstract: In a relay (100), right and left sides of an edge on an upper end side of an L-shaped armature (201) are bent to form an engagement portion (201a) and the armature 201 is held to be rocked and displaced through an energizing spring piece (205c) of a hinge spring (205) in a state in which the engagement portion (201a) is engaged with an edge portion 204c of an end face 204a on an upper end side of a core (204). During magnetic adsorption, moreover, an upper end of the armature (201) has an outer peripheral surface thereof to abut on the end face (204a) at the upper end side of the core (201) in a close contact state.

  • Patent number: 5752219
    Abstract: A navigation apparatus for a vehicle using a GPS (Global Positioning System) as sensing means in which information on the basis of sensing results, such as a present position, a running locus and the like are displayed in a predetermined form of display on a display section is disclosed. In cases where the GPS receiver cannot receive radio waves from artificial satellites, and sensing thus becomes disabled, a sensed final present position is displayed with an altered form of display.

  • Patent number: 5248981
    Abstract: A GPS receiver and related method for positioning on the Globe. The GPS receiver receives satellite signals in a sequential manner with a plurality of antennas, whereby any of the plurality of antennas which receives satellite signals from the maximum number of GPS satellites is selected by an antenna switching unit under the control of a control unit, a combination of GPS satellites having the smallest PDOP value or the signal strength in due order is selected by the control unit from among all of GPS satellites in contact with respective antennas when each of the antennas fails to receive satellite signals transmitted by the predetermined minimum number of GPS satellites.

  • Patent number: 4771253
    Abstract: An operation indicating device for electromagnetic relay which comprises a working member interlockable with an armature of an electromagnetic relay and extending into a space above a yoke, and an indicating member coupled to the working member and having an axis rotatably supported in the space above the yoke, the indicating member having a recognizable indicating portion and being rotatable by the working member interlocking with the armature during the operation of the armature, the indicating portion of indicating member thus rotated arriving at a position corresponding to an indication window formed in a case cover.When the armature is activated, the working member, interlockable with armature, is activated and the indicating member coupled to the working member is rotated around a supporting shaft serving as the fulcrum.
