Title: Manufacture of amorphous metal core
Inventor: YASUSE HIROAKI
IPC: H01F41/02
Filed: 1987-03-17
Abstract: PURPOSE:To obtain an amorphous metal core having preferably magnetic characteristics by cutting amorphous magnetic metal in advance to match the inner periphery of a toroidal case provided with a partition plate acting as a gap, and then piling it to fill the case to form substantially the same shape as that of the inner bottom in the case. CONSTITUTION:A partition plate 3 which acts as a gap is radially provided in a toroidal case 1 having a cylindrical protrusion 2 at a resin center. The length is suitably selected in a range of the length of an amorphous magnetic metal thin plate formed by subtracting the thickness of a threshold plate from the outer diameter of the protrusion 2 at the center of the case 1 to be used as the minimum to the length formed by subtracting the thickness of the partition plate from the inner diameter of the case 1 to be used as the maximum; the length is sequentially varied and cut. After the metal is heat treated at the crystallizing temperature or lass of the metal, it is sequentially piled to fill the case 1 radially along the circumferential direction, resin, such as epoxy is poured in the case, cured and secured. Thus, a gap having no separation between the layers, no drop, no burr can be formed to obtain excellent magnetic characteristics.

IPC: B65H69/06
Filed: 1987-03-16
Abstract: PURPOSE:To provide the titled system where nozzles jetting compressed air at both sides of the yarn-inserting slit of ending hole are set up in a specific state, thus enabling yarns of wide range of number counts to be brought to ending with sufficient strength. CONSTITUTION:Compressed air jet nozzles 24, 25 are set up non-tangentially on the inner peripheral wall surface 26 of both sides of the slit 22 of a cylindrical ending hole 2. Said nozzles 24, 25 are so arranged that their sectional forms at right angle to the direction of air flow are of flat and long channel such as rectangle or ellipsoid at any position along their air flow routes. A compressed air jetting from the wall surfaces of both sides of the slit impinges on the both yarn ends superposed over a wide range of the superposed area to effect firm entanglement of the fibers at the both yarn ends, thus making the single fibers coexist mutually.

Title: Reference voltage circuit
Inventor: SENBA TAKASHI
IPC: G05F3/30
Filed: 1989-03-13
Abstract: PURPOSE:To obtain the reference voltage having no dependency on the power supply fluctuation and the temperature fluctuation based on a 2nd power supply by obtaining the same temperature coefficient between the 1st and 2nd resistors and using a reference voltage source having no dependence on the power supply fluctuation and the temperature fluctuation. CONSTITUTION:A voltage follower which inputs the reference voltage V1 consists of an operational amplifier 1, a transistor TR 2, a 1st resistor 3, and a reference voltage source 5. The collector of the TR 2 is connected to an output terminal 6 and also to a 2nd power terminal 8 via a 2nd resistor 7. The temperature coefficients of both resistors 3 and 7 are set equal to each other so that R2/R1 is kept constant when the resistance values of the 1st and 2nd resistors are referred to as R1 and R2. Then the source 5 is stable to the power supply fluctuation and the temperature fluctuation. Thus it is possible to obtain a reference output that is subject to a 2nd power supply and not dependent on the fluctuation of both the power supply and the temperature.

Title: Magnetic head and magnetic recording device
Inventor: MARUYAMA YOJI
IPC: G11B5/02
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To reproduce high-density magnetic information close to the position in the longitudinal direction of a magnetoresistive film by providing an open termination line being constituted by the magnetoresistive film in a magnetic head, applying a high-frequency voltage, and detecting the presence of a reflection wave caused by an obtained, local resistance change. SOLUTION: A high-frequency voltage is applied to an open termination line 40 from a high-frequency lower supply 54. When there is a local resistance change in a magnetoresistive film, a reflection wave is generated at that part. A transmission line of a high-frequency voltage wave containing the reflection wave from the magnetoresistive film (a path via an amplifier 52) is provided in parallel with a transmission line from a high-frequency voltage source (a path via an amplifier 53) and the amplitude and the phase of a waveform from each transmission line are compared by a phase/amplitude comparator 61. The direction of the phase of the high-frequency voltage waveform is inverted at a part where a resistance is changed.  The frequency of the high-frequency voltage is changed and distance information up to a detection point is obtained, thus detecting the existence position of a plurality of magnetic information close to the arbitrary place of the longitudinal direction of the magnetoresistive film simultaneously.

Title: Co2 laser device
Inventor: UESUGI FUMIHIKO
IPC: H01S3/036
Filed: 1983-04-08
Abstract: PURPOSE:To perform high repetition of laser oscillation by flowing gas, further rotating electrodes, thereby completely removing discharge product which disturbs the high speed repetition of laser oscillation from the discharge space. CONSTITUTION:A discharge procut produced due to discharge is forcibly flowed to the downstream side of the discharge space 22 via the stream 21 of laser gas. At this time, electrodes 11, 12 are rotated around rotational shafts 14, 15. Thus, a boundary layer in the electrode surface is not formed. Accordingly, the product does not remain in the space 22. Thus, high speed repetition oscillation can be performed. For example, when the electrodes 11, 12 are rotated at 30 times/sec the laser can be oscillated at 120pps. The moving time of the electrode 13 due to rotation is sufficiently long as compared with the discharge continuing time. Consequently, the discharge is not disturbed by the rotation of the electrodes.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent an uneven flow of vapor in a distillation column to improve distillation efficiency by arranging a vapor dispersing device which has an opening downward from the horizontal direction and the horizontal projected sectional area of the opening is specified percent of the column sectional area, at a vapor inlet part provided on the side face in a refining device. SOLUTION: A vapor dispersing device 1 is installed in a distillation column and has an vapor opening 6 in which jetting of vapor from a reboiler vapor nozzle 2 is made downward from the horizontal directional and the horizontal projected sectional area of the vapor opening 6 is 10-40% of the column sectional area. By jetting vapor from the reboiler vapor nozzle 2 downward, the vapor from the reboiler is caused to flow downward in the distillation device once, and when it rises again, it is uniformly dispersed in the column sectional area after sufficient time has passed. As a result, an uneven flow of gas-liquid near the column bottom part is restrained, gas-liquid contact is sufficiently performed to improve separation efficiency.  Preferably, the opening sectional area of the vapor dispersing device is specified as 10-40% of the column sectional area, because an uneven flow of the vapor and entrainment of the bottom liquid can be restrained.
