    摘要: A fault diagnosis circuit of the present invention includes: LED indicating units 3a, 3b, and so forth; current detecting circuits R1 and Q1 for detecting a flowing current by flowing a short-time pulse of a current through the LED indicating units 3a, 3b, and so forth based on pulses generated by a pulse generating circuit 7; comparing circuits 8 and 9 for comparing a current value detected by the current detecting circuits R1 and Q1 with their respective threshold values to judge a disconnection and a short-circuit; and retaining circuits 10 and 11 for generating a signal and retaining the signal when the current value is judged as being smaller and larger than the respective threshold values as a result of comparisons by the corresponding comparing circuits 8 and 9. Thus, it is possible to indicate a fault in an LED indicating light to the outside while making the turning ON of an LED unperceivable.

    摘要: A lens component radiates light from a light source. The lens component includes a light guiding radiation portion. The light guiding radiation portion includes a light incidence portion having an incidence surface on which the light from the light source is made incident, and a plurality of radiation mechanisms that respectively radiate to a plurality of radiation angle ranges. The incidence surface includes a close side incidence region and a distant side incidence region. The radiation angle ranges include a close side radiation angle range and a distant side radiation angle range. The light incident on the close side incidence region is radiated to the distant side radiation angle range via a corresponding distant side radiation mechanism. The light incident on the distant side incidence region is radiated to the close side radiation angle range via a corresponding close side radiation mechanism.

    摘要: A plurality of signal display lamps 1A to 1E are communicably connected together through a network 3. Each of the signal display lamps 1A to 1E includes a display portion 12 capable of performing a variable display. Each of the signal display lamps 1A to 1E is capable of performing a mirroring operation in addition to being capable of performing a variable display in the display portion 12 in response to an input signal that is input from input signal lines 8A to 8E. For example, in the signal display lamp 1A, any of the signal display lamps 1B to 1E is selected, and its display state can be simulated. Each of the mirroring source signal display lamps 1B to 1E can be selected by giving a selective command signal from a selective-command-signal generating device 60 connected to the input signal line 8 of the signal display lamp 1A. The selective command of the mirroring source signal display lamp 1 may be given to the signal display lamp 1A from an information-processing terminal device 10 through the network 3.

    摘要: A buzzer unit 4 includes a case 10, a vibrating element 11, and a pressing member 14. The case 10 includes a vibrating plate 28 in which no through-holes are formed. The case 10 includes a storage space 22 formed therein on the lower side X2 of the vibrating plate 28. The vibrating element 11 faces the vibrating plate 28 in the vertical direction X inside the storage space 22, produces vibration as a result of voltage being applied thereto, and as a result, causes the vibrating plate 28 to vibrate. The pressing member 14 is stored in the storage space 22, and presses the vibrating element 11 against the vibrating plate 28.
