Title: Threshold value setting device
Inventor: INAGAKI YOSHIO
IPC: H04B10/80
Filed: 1989-07-12
Abstract: PURPOSE:To set an optimum threshold level simply in a short time by using a threshold level setting circuit so as to vary a threshold voltage in a way that a probability of an identification circuit misdiscriminating the amplitude of an inputted signal is made equal. CONSTITUTION:A threshold level setting circuit 7 outputting 1st, 2nd and 3rd threshold voltages arranged at an equal voltage interval in the lower order impresses the 1st threshold voltage to an identification circuit 4. The 1st and 3rd threshold voltages are adjusted so that an error rate of misdiscriminating the read of a binary code signal led to the identification circuit 4 by the identification circuit 4 and an error rate of misdiscriminating the 3rd threshold voltage impressed to the identification circuit 4 by the identification circuit 4 are made equal. Then the 2nd threshold voltage when both the error rates are identical is used as the threshold level of the identification 4. Thus, an optimum threshold level is simply set.

Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To allow a pressed excavation process and a forced pile drive by applying the constitution that a bracket for mounting an auger drive motor and a pile forcing device is caused to slide via the expansion and contraction of a hydraulic cylinder. SOLUTION: Upon the expansion of a hydraulic cylinder 7, an end leader 4b as well expands by the same length. Concurrently, an upper sprocket 10 ascends by the same length, and an auger drive motor 5 or a bracket 6 ascends over a distance two times as long as the expansion of the cylinder 7, due to the travel of an upper chain 15 wound around the sprocket 10. Then, when an earth auger is mounted on the motor 5 or a pile forcing device is mounted on the bracket 6 for holding a pile and the cylinder 7 is made to contract, the motor 5 or the bracket 6 descends over a distance two times, as long as the dcontraction of the cylinder 7. At the same time, a lower sprocket 13 descends by a distance equivalent to the contraction of the cylinder 7 and a downward pressing force acts on the motor 5 or the bracrket 6 via a lower chain 14, thereby keeping a sufficient biting amount.

Title: System for controlling training operation of in-model automatic equalizer
Inventor: EBIHARA SEIJI
IPC: H04B3/10
Filed: 1984-08-30
Abstract: PURPOSE:To cause training by means of the 1st sequence of the automatic equalizer inside the partner MODEM to be performed surely, by giving a training signal by means of the 1st sequence after it is confirmed that the partner MODEM is connected with a circuit and power supply is made. CONSTITUTION:At the time of the 1st transition of a signal RS from OFF to ON an ON signal is given to an AND gate 7 from the Q-terminal of a D-FF and the output of the AND gate 7 changes from OFF to ON. When the signal RS becomes OFF, the output of an inverter 3 changes from OFF to ON and, therefore, an ON signal is given to one side input terminal of another AND gate 8. Since the ON signal is given whenever the signal RS becomes ON thereafter, the 2nd sequence circuit 2 operates. Since the training signal by means of the 1st sequence circuit 1 is sent after the 1st carrier is completed, the partner MODEM can receive this training signal and the training of an automatic equalizer can be executed.

Abstract: PROBLEM TO BE SOLVED: To reduce a video signal at an optional reduction rate without deteriorating the image quality such as loopback distortion by applying sub sampling to an input video signal while applying prescribed filtering processing and recording only prescribed data. SOLUTION: In reduction in a horizontal direction, multipliers 6, 7 multiply signals 5a, 5b from a counter 5 with an input video signal 1, a 1 clock delay element 8 delays an output of the multiplier 7 by one clock time, an output of a switch 9 is summed to an output signal of the multiplier 6 by an adder 10, a 1 clock delay element 11 delays an output of the adder 10 by one clock and a line memory 12 stores the delayed signal. Let a reduction rate be n/M and number of bits of the counter 5 be p, then a relation of M=2(p-1) holds, and let k be a value excluding the most significant bit from the count value and let h be exclusive ORing between the most significant bit before the delay and the count value, then a signal 5b results from ORing the k and h and a signal 5a is a value resulting from substrating the signal 5b from the (n).  The reduction in a vertical direction is conducted by the similar configuration to above.
