Title: Data multiplex transmission method using pair line, system and device therefor
Inventor: IWAI MASASHI
IPC: H04L5/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To enable frequency multiplex transmission using two pairs of pair lines. SOLUTION: This transmission system uses two pairs of pair lines, consisting of a central control unit 100 which performs transmission and reception by a low frequency polling system of a frequency fL and an opening and a switch controller 200. A low frequency data signal fL devices the pair lines into incoming and outgoing ones. For a high frequency data signal fH, the two pairs of pair lines are both bidirectional transmission. As each of the pair lines is 5 Mbps and performs parallel transmission by two pairs of pair lines, fast transmission of 10 Mbps is possible. At the transmitting of the high frequency data signal to a transmission line, a monitoring current I is made to reflux from balance resistances R11 and R21 via way of a connection resistance (r) of a pair line terminal.  The utility state of the transmission line has balance resistance R12 and R22 and a monitoring resistance Ro connected in an intermediate point between the two detect this monitoring voltage. When the monitoring voltage is more than a specified value, the transmission is in using state. Since the monitoring voltage does not occur between each pair lines, it does not affect the low frequency data signal.

Title: Production of magnetic paint for magnetic recording
Inventor: OGASA KAZUO
IPC: G11B5/842
Filed: 1985-05-18
Abstract: PURPOSE:To decrease the abrasion loss of kneading balls and worn powder and to extend the life of the kneading balls by consisting essentially said balls of zirconium oxide as main component and specifying the ratio of yttria Y2O3 to specific % or below. CONSTITUTION:The kneading balls consisting essentially of the zirconium oxide are used. More specifically, the kneading balls are formed by adding the yttria (Y2O3) as an assistant to the zirconium oxide, sintering the mixture and specifying the ratio of the yttria to <=6%. Since the content of the zirconium oxide is low, the specific gravity is larger than the specific gravity of alumina balls and is slightly smaller than the specific gravity of the conventional zirconia balls. Since the smooth and uniform dispersion of the magnetic paint is made possible, there is no need for dispersing the paint for a long period of time and the wear resistance of the kneading balls themselves is high and the size of the worn powder is small. The repetitive uses of the kneading balls are thus made possible and particularly the quantity of the worn powder is decreased. Since the size of the worn powder is small, the bit error and head crash of a magnetic disk medium are decreased and the magnetic characteristics are improved.
