Title: Amplifier for mr head
Inventor: UMEYAMA TAKEHIKO
IPC: H03F3/45
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To eliminate an effect upon an MR head due to disturbance with simple constitution by extracting a component of a disturbance signal from a synthetic signal at the time of inputting the synthetic signal on which the disturbance signal is superimposed, reversing a phase of this disturbance signal and adding this signal to the synthetic signal. SOLUTION: When a signal consisting of a data signal and the disturbance signal, superimposed over each other is inputted into a disturbance signal suppressing circuit 133 through input terminals 1 and 2 respectively, an input signal waveform is sent to an amplifier 203 and LPFs 201 and 202, while this signal at A point is also sent to an LPF changeover signal generating circuit 301. When the data signal on which a disturbance waveform is superimposed is inputted, the LPFs 201 and 202 act as LPF having a cut-off frequency of, for example, a several MHz by an output of the circuit 301, and hence only the disturbance waveform can be taken out.  After a DC level of an amplifier 206 is matched with that of the amplifier 203 by DC level adjusting circuits 204 and 205, this disturbance waveform is added by reversing its phase to the original signal, thus canceling only the disturbance waveform.

Patent JP-H11125798-A (JP)
Title: Optical isolator
Inventor: SATO TADAKUNI
IPC: G02B27/28
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To lessen the change in the temp. of isolation by restricting the shape of magnets for impressing magnetic fields on a Faraday rotating element to a specific range. SOLUTION: The length in the magnetization direction of the Sm2 Co17 , based magnet and Nd-Fe-B based magnet constituted to include the Faraday rotating element and to impress the magnetic fields thereon is defined as L and such a cross sectional area that intersects orthogonally therewith is defined as S. L/(S)<1/2> is then specified to a range of 0.7 to 5.5 in the case of the Sm2 C16 based magnet and to a range of 0.7 to 5.5 in the case of the Nd-Fe-b based magnet. The reason for the limitation to the ranges described above is as follows: The decreasing rate of the isolation evidently increases if L/(S)<1/2> is <=0.6 in the case of the Sm2 Co17 based magnet and of <=0.7 in the case of the Nd-Fe-B based magnet.  When the values exceed 5.5 in the case of both of the Sm2 Co17 based magnet and the Nd-Fe-B based magnet, the shape increases and the industrial usability degrades in terms of the effective utilization rate of the magnetic fields. As a result, the decrease in magnetic fields is lessened from the relation between the temp. change of the magnetization curve of the magnets and the diamagnetic field by the shape.

Filed: 1989-11-29
Abstract: PURPOSE:To obtain a welded joint with high reliability by forming one end of a deformed reinforcing bar at least into a cylinder and further, working the end face thereof to a plane orthogonal to an axis of the reinforcing bar. CONSTITUTION:This is the welding process where the relation between the length Lmm of a cylindrical part 8 and the length Smm of shielding material 2 satisfies the conditional expression of the expression I. The tip 8 of a deformed reinforcing bar stud is worked into the cylinder and in accordance with the movement of the stud during stud welding, the difference between the height of a knot 4 and a rib 4', and a clearance 5 of a knot of a region 10 to interfere with the shielding material 2 is made to the extent that can be disregarded. Thus, narrowing of spatters and mechanical interference of the knot part and the rib part of the deformed reinforcing bar with a shielding inwall end part are prevented and a pressing-in action at the optimum speed and the necessary pressing-in quantity can be secured and the reliable welded joint without weld defects can be formed. By this method, since the deformed reinforcing bar whose tip is formed into the cylinder and further, which is worked so that stud welding can be performed is used, the welded joint with high reliability can be produced by arc stud welding.

Abstract: PURPOSE:To obtain a film having uniform physical properties by orienting the film in the cross direction, cooling the film at a glass transition point or less under limiting conditions and conducting first and second stage thermal fixing at a specific temperature by a tenter and a roll. CONSTITUTION:When a polyamide film is laterally oriented and thermally fixed and treated, the film before a thermal fixing process is cooled at a glass transition point or less, and a bowing phenomenon generated by a lateral orienting process is reduced. The effect of the bowing phenomenon is improved with the lowering of the cooling temperature, and the ratio of the length L of a cooling process to the width W of the film L/W>=1.0 may be satisfied. The length L of the cooling process means length from a section substantially brought to the temperature or lower of the pre-process of the cooling process to the longest section up to the temperature of the next process substantially higher than the temperature of the cooling process, and film width W means a distance between the clips of a tenter in the outlet of the tenter. Thermal fixing at a second stage is conducted while performing slackness or orientation within a range of 10% or less at a temperature lower than Tm-20 deg.C by the tenter and further at a temperature higher than (Tm-60) deg.C by a roll.
