Title: Machining track generating method for cutting tool and cutting method for metal mold
Inventor: NAKAHIRO MIKIO
IPC: G05B19/4093
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To actualize a simple machining track generating method for cutting tool which makes it easy to set the pick feed of a small-sized tool in cutting and can surely prevent the cutting tool from interfering with a metallic material at a cutting completion part. SOLUTION: When the metallic material M1 is cut (profile machining) by using 1st to 3rd cutting tools 4 to 6, the movement path 20 of the 2nd cutting tool 5 is generated by using the machining track 7 of the 1st cutting tool 4 as the pick feed of the 2nd cutting tool 5. Further, the movement path 21 of the 3rd cutting tool 6 is generated by using the virtual machining track 8 of the 2nd cutting tool 5 as the pick feed of the 3rd cutting tool 6. Consequently, the pick feeds can easily be generated which can surely prevent the 2nd and 3rd cutting tools 5 and 6 from interfering with the metallic material M1 at the cutting completion part.

Title: Reproduced signal detecting circuit of optical information recording and reproducing device
Inventor: MORITSUGU MASAHARU
IPC: G11B7/005
Filed: 1991-09-20
Abstract: PURPOSE:To improve the reliability of information reproduction on an optical disk by generating a slice level according to the difference between the maximum value of the signal of a data start part and the maximum value of the signal of the following area and slicing the signal according to the level. CONSTITUTION:The reproduced signal from a gap part is separated by an amplifier 21 into a positive-polarity signal and a negative-polarity signal, and holders 22 and 23 detects their peak value and bottom value; and a difference circuit 24 calculates their difference and the difference signal is sampled and held. The difference signal generated by subtracting the sampled and held signal from the signal amplitude between the peak value and bottom value of the reproduced signal from a data part is multiplied by 1/2 through a multiplier 27 to become the slice level. A comparator 28 compares the signal from the amplifier 21 with the slice level and outputs a high level 1 when the signal is larger than the slice level, thereby converting the reproduced signal into a binary signal. Consequently, the accurate slice level is detected from the reproduced signal to stably read the signal out of the optical disk.
