Title: Production of binder for magnetic recording medium and magnetic recording medium
Inventor: MEGURO KATSUHIKO
IPC: C09D201/06
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To improve the travelling durability of recording media by removing a low mol.wt. component of a binder having 10000 to 60000 weight average mol.wt. through a filter film so that a low mol.wt. component having <=5000mol. wt. is included by <=3wt.% of the whole binder. SOLUTION: The low mol.wt. component of a binder resin having 10000 to 60000 weight average mol.wt. is removed by using an ultrafilter. The ultrafilter film has 5 to 50nm average pore diameter and consists of a ceramic material. The binder resin soln. has <=40cP viscosity and is treated by heating to a temp. 5 deg.C lower than the boiling point of the solvent having the lowest boiling point of the solvents in the resin soln. If the average pore diameter of the ultrafilter film is <5nm, only a part of the low mol.wt. component in the binder resin is removed. If the diameter exceeds 50nm, a component having >=5000mol. wt. is also removed, which decreases the production yield. By controlling the proportion of the low mol.wt. component having <=5000mol.wt. to <=3wt.% of the whole binder, contamination and clogging of a head can be prevented.

Title: Differentiation phase characteristic evaluation system for analog/digital converter
Inventor: KUTSUNO TAKAO
IPC: H03M1/10
Filed: 1986-07-18
Abstract: PURPOSE:To improve the evaluation accuracy of differentiation phase characteristics by correcting a phase value of each stair by the quantity of phase compensation and evaluating the differentiation phase characteristics of an analog/digital converter based on the phase value after correction. CONSTITUTION:A video generator 12 inputs a measuring video signal to the analog/digital converter 10, calculates the phase of a chrominance subcarrier in a specific position of each stair from the conversion output data and calculates the quantity of phase compensation to each stair proportional to the phase fluctuation depending on the frequency deviation of a sampling clock from the difference of the calculated phase value in at least two stairs. Thus, when the phase quantity of each stair is corrected depending on the phase compensation quantity, the effect caused by the frequency deviation of the sampling clock is compensated nearly completely and the differentiation phase characteristics of the analog/digital converter 10 are evaluated with high accuracy based on the phase after the correction.

CONSTITUTION:Yokes 15 and 16 each constituted of a member of a soft magnetic material and having a U-shaped section taken along a plane parallel to the axial line of a passive shaft are provided. The yokes 15 and 16 are formed of soft magnetic material so as to have the U-shaped section and cover detection coils 8 and 9, and thereby magnetic fluxes generated from the detection coils 8 and 9 are made to flow in a concentrated manner through magnetic layers 5 and 6, so that a leakage of the magnetic fluxes is prevented. Accordingly, magnetic fields which are generated by making a current flow through the detection coils 8 and 9 and impressed on the magnetic layers 5 and 6 act effectively on these layers, and therefore the sensitivity of detection of a strain is improved. Since the respective parts of the yokes 15 and 16 exist between the detection coils 8 and 9, besides, the magnetic fluxes flowing between the detection coils 8 and 9 mutually can be suppressed as well, and therefore the precision of detection of the strain is also improved. In addition, the yokes 15 and 16 are prepared by a technique of powder metallurgy, and therefore they have a simple structure, are assembled with ease and can be prepared inexpensively.

IPC: H04Q1/56
Filed: 1984-08-16
Abstract: PURPOSE:To select always an optimum balanced network and to improve the call quality such as an increase in singing allowance and enhancement of a side tone characteristic by measuring a DC call current and estimating a line impedance. CONSTITUTION:A block in the figure at the left side is a trunk line trunk part contained in a PBX, while a block B in the figure at the right side includes a line 13 controlled by said trunk line trunk and a subscriber circuit 14 of a station. Assuming that an impedance which views the circuit 14 for including the line 13 from a trunk line trunk A is Zx and an impedance of a balanced network corresponding to an analog switch 4 in the on state is ZBi, the amount that an output V1 of a buffer amplifier 1 goes around an output V4 of a differential amplifier 5 is minimized when the ZBi equals to the Zx. On the other hand, an impedance ZL of the line 13 is uniquely decided by a line material and loop length. Since a real part of the ZL is practically equal to its DC resistance, the loop length can be conversely found from the DC resistance, and the ZL for including an imaginary part can be sufficiently estimated.
