A phosphor indication device suitable for use as a meter of a vehicle including an indication section having a pattern and characters to be indicated which are printed with at least one ordinary paint and at least one paint containing a phosphor differing in color when it is exposed to light capable of exciting the phosphor to emit light in fluorescence from when it is exposed to ordinary light unable to excite the phosphor to emit light. The pattern and characters of the indication section may ...

In a dot-matrix type vehicle condition display apparatus, binary coded signals corresponding to items to be displayed on a dot-matrix type fluorescent display tube are applied to portions of address input terminals of a memory, while binary coded signals corresponding to ordinal numbers of character columns of the items to be displayed are applied to other address input terminals of the memory. The memory produces a binary coded output corresponding to a character determined by signals at those ...

A vehicle-mounted message apparatus comprising a device for converting a voice into an electrical signal, storing it in a memory, and reproducing and confirming automatically the stored data after being stored, a device for reproducing the stored data into a voice when required, and a device for erasing the stored data after reproducing the same for confirmation in response to a starting switch.

A plurality of sensors are provided each sensing a different condition occurring in a motor vehicle. Each sensor supplies a signal to a converter which converts the signals into a four-digit binary coded signal. A plurality of condition indicating panels, each bearing up to four projections, sequentially move past a stationary switch arrangement to open at least one of four normally closed switches to produce further binary coded signals. A digital comparator compares the four-digit binary signa...
