Title: Instrument for measuring distance by light wave and light quantity control method therefor
Inventor: YAMAMOTO KIYOSHI
IPC: G01S17/36
Filed: 1995-03-24
Abstract: PURPOSE: To easily set the position of a concentration distribution filter by preserving the state information about the position of the filter when the power supply is turned off and using the state information as a reference state for controlling light quantity adjustment when the power supply is turned on next. CONSTITUTION: An instrument 100 for measuring distance by light wave preserves the state information about the last position of a filter in a nonvolatile memory 18 when the power supply is turned off and updates the state information by reading the preserved information from the memory 18 and calculating the moved position of the filter based on the read value and displacement of the filter. Therefore, the instrument 100 can immediately execute distance measurement without requiring initialization. In addition, since the reliability of the filter position control drops due to accumulated errors when the control only relies upon the relative position in such a way, the reliability of the position control of the instrument 100 is secured by eliminating errors by forcing the device 10 to perform origin position detecting processing.

Title: Communication procedure system for facsimile equipment

IPC: H04N1/32
Filed: 1985-04-30
Abstract: PURPOSE:To attain the reception of an MSG signal by using a single tone at the outside of the frequency band of a facsimile message signal MSG corresponding to a reception acknowledgment, a message acknowledgment signal and a training failure signal. CONSTITUTION:Since a training check signal TCF and a facsimile message signal MSG are combined and they are handled as a series of high-speed data signals, the signals TCF and MSG are received by using one training signal and sent in the same reception state. In case of multi pages, since the high speed data communication is not interrupted even between pages, the reception state between the pages is kept constant. Thus, in a conventional system, since the reception state between the training check signal TCF and the facsimile message signal MSG differs in a line where the operation of the MODEM approaches it limit, even when it is discriminated that the signal TCF is communicated, while the signal MSG might not be communicated, but in this system, when it is discriminated that the signal TCF is communicated, the signal MSG is received while keeping the reception state and the signal MSG is sent surely.
