  • Patent number: 5341221
    Abstract: A facsimile apparatus for transmitting an image of an original. Image data is obtained by reading the original image and is stored. The resolution of the stored image data is converted into a desired resolution according to a nominal resolution of the apparatus based on a predetermined facsimile procedure, and the image data having the converted resolution is transmitted.
    Type: Grant

  • Patent number: 4677649
    Abstract: The present invention provides a data receiving apparatus constituted in such a manner that the received data is converted into a binary code and this binary code data is encoded and this encoded data is stored in a memory, whereby a large quantity of data can be stored in a memory of a small capacity. After subsequently decoding the received encoded data, this decoded data is further encoded by another encoding means and this encoded data is stored in the memory, thereby providing an efficient and economical data receiving apparatus which can smoothly perform the data processing even in the case where the transmission speed of the data and the recording speed of the recording apparatus remarkably differ.

  • Patent number: 4099247
    Abstract: An electronic instrument with a non-volatile display comprises a drive control circuit for controlling the display, first and second clear means for respectively clearing the non-volatile display and the drive control circuit, and a single clear instruction generating circuit for generating a signal to actuate both first and second clear means. Thus the non-volatile display and the control circuit may be cleared simultaneously.

  • Patent number: 4065803
    Abstract: There is disclosed an electronic device which comprises means for detecting the occurrence of voltage fluctuation in the input or output voltage of a power source to produce an output signal, and means operative in response to the output signal for disabling a portion of the electronic device, such as a liquid crystal display element, thereby substantially elongating the lifetime of the particular portion of the electronic device.
