Title: Automatic answering telephone set
Inventor: IWASE SUMIO
IPC: H04M1/00
Filed: 1985-07-19
Abstract: PURPOSE:To prevent a device from being set to an erroneous state by ignoring the processing or the operation executed up to that time to set the holding state if key input is performed over a prescribed limit time at the key input time. CONSTITUTION:In case of key input from a dial key 11, the processing or the operation executed up to that time is ignored to set the holding state by the control of a system controller 40 if it is detected by a timer 54 that the time of key input exceeds the limit time. Consequently, the trouble that the device is set to an erroneous state is reduced. Since the processing or the operation is ignored similarly if the time key input exceeds the limit time with respect to key input using the dial key of an external telephone, the device is effective against mischief and disturbance.

Title: Method of and apparatus for detecting magnetic line of force
Inventor: NANBA AKIHIRO
IPC: G01R33/07
Filed: 1981-10-09
Abstract: PURPOSE:To achieve a higher detection sensitivity and an integrated circuit conversion by detecting an electrode piece with the maximum current flowing among electrode pieces after one of electrodes for running a constant current to a Hall element is divided into the electrode pieces. CONSTITUTION:While no magnetic field is applied to a Hall element 11, current I fed to the element 11 from a first electrode 12 reaches a second electrode 13 subjected to no Rorentz's force. At this point, among electrode pieces 13a,13b... 13n composing the electrode 13, current reaches its maximum at the one in the center facing the electrode 12 and reduces toward the end thereof. Here, as a magnetic field is applied to the Hall element 11, the current I flowing through the element 1 at a fixed current value is deviated according to the intensity of the magnetic field. Thus, output current of the electrode piece 13 causes change in the collector voltage of transistor Tr through the bases of transistors Tr, Ta, Tb and Tn of a current detection circuit 14. The voltage is read out with a switching circuit 16 and converted according to a conversion table of the intensity of magnetic field memorized beforehand.

Title: Data reader
Inventor: KATOU YOSHIAKI
IPC: G06F11/00
Filed: 1977-12-28
Abstract: PURPOSE: To prevent malfunction through reading of noise data by discriminating the data before and behind the separator and the same when the separator of the data is less than the specified spacing.  
     CONSTITUTION: When the signal IN applied to input terminal IT 1 is applied to the clear terminal CL of a counter CNT via inverter i 1 , AND gate AG 1, the content of the CNT is cleared. When the Q output of a flip-flop FF becomes "1", the data block signals begin to be produced from ouput terminal OUT, in correspondence to which the signals read out from a recording medium are transferred. When there is no more signal IN, the signal ϕ applied to a NAND gate ND 1 is applied to the terminal IN of the CNT. When the content of the CNT counts the specified number, the ND 2 produces a signal SRBL and the FF reads the signal "0" being applied to the input terminal D and makes its Q output "0", thereby stopping the transfer of the read signals from the medium. Thereby, the malfunction by noise data may be prevented.
