Filed: 1979-10-15
Abstract: PURPOSE: To simplify the head leading device of a tape recorder, by stopping the tape driving motor for a fixed time by the intra-data detection signal and then giving a display of detection for a fixed time.  
     CONSTITUTION: The high-speed reproduction signal applied to the input terminal IN is shaped by the saturation amplifier 141 having the clamping function and then detected through the detection circuit 142. Thus the presence or absence is decided for the intra-data part detection signal by the Schmitt circuit 143. The 1st and 2nd transistors Q 1  and Q 2  of the head leading detection signal generating circuit are turned on when the base potential at the point A is lowered through the charging/ discharging capacitor C 1  and when the nonsignal part is detected. The head leading detection signal supplied from the transistor Q 1  gives an inversion to the transistors Q 3  and Q 4  which form the motor driving circuit 17 and at the same time gives a pause to the motor 16 for a fixed time. The signal from the transistor Q 2  gives the driving voltage to the alarm display circuit 22 and the alarm oscillating circuit 23 for warning.

Title: Error detection system
Inventor: KADOKAWA YUICHI
IPC: G11B20/18
Filed: 1989-05-29
Abstract: PURPOSE:To stably detect an error by finding the difference in feature quantity between an (n)th and an (n+1)th large channel bit and detecting a decoding error when the difference value is smaller than a predetermined value. CONSTITUTION:A '1'-channel bit detecting circuit 3 while outputting data finds the amplitude difference between a 4th channel bit and a 5th channel bit and sends this difference value (d) to a comparing circuit 6. The comparing circuit 6 compares the difference value (d) with the predetermined threshold value S. When a recording medium has none of a defect, dust, and a flaw, the difference between the both is extremely large, but when there is a flaw, the difference in amplitude between the both is small. When the difference value becomes smaller than the specific threshold value, a decoding error is detected and then even if an error such as a bit pattern matching a modulation rule is caused, the error can be detected.

Abstract: PURPOSE:To enable to perform efficient mixture and agitation in a vertical direction,  by a method wherein a plural number of rotary longitudinal shafts is arranged so that  they spin in the same direction as that of each other, and a spiral direction of a screw part is set in a reverse direction to that of a screw part attached to an adjacent rotary  longitudinal shaft. CONSTITUTION:With a rotary device 1 spun, rotary longitudinal shafts 2 are turned,  and the ground is excavated as an earth and sand solidifying agent such as cement  milk is jetted through a bit 5 at the forward end of the rotary shaft.
