Title: Karman vortex current meter
Inventor: ASAYAMA YOSHIAKI
IPC: G01F1/32
Filed: 1978-02-09
Abstract: PURPOSE: To make detection of vortex generating frequencies easy even at low velocities by  providing temperature differences, etc. between the measuring fluids on both sides of a vortex  generating column on the upstream side of the vortex generating column in measuring the velocities of flow by detecting the number of Karman vortexes generating on the lower stream of the  vortex generating column with ultrasonic waves.   
     CONSTITUTION: When fluid flows in a conduit 1, a vortex generating column 2 generates  Karman vortexes 3, 4. An ultrasonic wave transmitter 5, driven by an oscillator 6, transmits  ultrasonic waves to a receiver 7. Then, the ultrasonic waves are modulated by the Karman vortexes and the modulated ultrasonic waves are received in the receiver 7. In a reception unit 8, the  generation frequencies of the Karman vortexes are detected. When the velocity  of flow of the  fluid is low, the Karman vortexes are weak  and give lower degrees of modulation and therefore a  temperature difference is given between the clockwise Karman vortexes and the counterclockwise  Karman vortexes by heating the fluid of the B side with an electric heater 10. As a result, the  ultrasonic waves propagaging become those which have been applied with the modulation by the  Karman vortexes and the modulation owing to the  differences in the rate of propagation by the  temperature differences between the Karman vortexes 3 and 4, thus it becomes possible to readily  detect the Karman vortexes of low velocity of flow.

Abstract: PURPOSE:To detect the jamming of paper, by providing a tractor imparting feed to continuous paper, a rotary body engaging with the sprocket holes of the continuous paper and rotated in synchronous relation to the feed of the continuous paper and a magnetic sensor detecting the rotation of the rotary body on the basis of the magnetic marker integrally rotating along with the rotary body. CONSTITUTION:Continuous paper 1 is fed in one direction by a tractor 4 while printed by a head 6. Each of rotary bodies 2 is rotated when the paper 1 is fed and the magnet markers 3 mounted on the rotary bodies 2 are also rotated. Magnet sensors 5 are fixed and detect the magnet markers 3 when said markers 3 make one revolution. When the detected quantity of rotation of each of the rotary bodies 2 by each of the magnetic sensors 5 does not coincide with the feed quantity of the paper, it is judged that jamming is generated in the feed direction of the paper. Since the rotary bodies 2 are arranged corresponding to both sides of the paper 1, when the paper 1 is shifted to the left and right, one rotary body 2 is detached and released from the sprocket holes of the paper 1 to stop and the jamming of the paper due to left/right shift can be also detected.

Title: Soft magnetic thin film
Inventor: IWASAKI HIROSHI
IPC: H01F10/14
Filed: 1993-02-02
Abstract: PURPOSE:To contrive the improvement of a reduction in the magnetic characteristics of a soft magnetic thin film, the improvement of the unstableness of the thin film and the improvement of an irregulartiy in the thin film by a method wherein a base film is formed into a Pt film, the crystal grain direction distribution of a metal soft magnetic thin film is formed in almost a symmetrical manner to one axis and the central axis of symmetry is made to coincide with the direction of the normal of the surface of the soft magnetic thin film. CONSTITUTION:A metal soft magnetic film 33 is formed via a base film 32, such as a Pt film and an Au film, and an isotropy of the crystal grain direction distribution of the film 33 within the film surface is performed, whereby even if a material of the comparatively large constant K1 of a crystal magnetic anisotropy is used, the appearance of this in-plane crystal magnetic anisotropy can be regulated. As a result, the strictness of a selection of a magnetic material composition can be relaxed add moreover, the degree of freedom of a selection of the magnetic material composition is increased. Accordingly, the formation of a soft magnetic film of a high saturation magnetic flux density becomes possible with this increase. Moreover, as an X-ray circuit strength distribution on the extreme point drawing of the crystal faces 110 and 200 is specified and a superior isotropic low coercive force is obtained, the soft magnetic thin film can be reliably obtained regardless of an irregularity in adhesion formation conditions and an irregularity in the directions of incidence of film- forming material particles.

Title: Thin film magnetic head
Inventor: FUKAZAWA TOSHIO
IPC: G11B5/29
Filed: 1993-01-05
Abstract: PURPOSE:To obtain a thin film magnetic head capable of effectively recording/ reproducing signals without generating an azimuth loss even when a tape traveling direction is inverted in respect to a thin film magnetic head to be used for a magnetic tape device having an autoreverse function. CONSTITUTION:Two head parts 1, 2 of the thin film magnetic head constituted of forming the head parts 1, 2 on bases 11, 12 so as to record/reproduce signals by about 1/2 width of a magnetic tape are aligned so that the 1/2 width parts of the tape are not mutually overlapped and both the rear faces of respective bases 11, 12 are mutually fixed. Since the magnetic head can deal with the inversion of the tape traveling direction by changing the selection of the head part 1 or 2, the rotation of the head is made unnecessary and effective recording/reproducing free from azimuth loss can be attained.

IPC: B29L17/00
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To use a stamper of long life for molding and mold by introducing a raw material gas composed of hydrocarbon gas, as a main component, ionizing the same, carrying out the deposit separation on the back of the stamper to form a diamond-shaped film to be coated thereon, supporting the stamper in a molding die cavity and injecting resin. SOLUTION: A diamond shaped film is formed on the back 8 of a stamper in an ordinary film manufacturing device. As the diamond-shaped film is formed on the back 8 of the stamper 1 of a molding die, the life of the stamper 1 can be prolonged to a large extent. Also as it is hard to form marks on the stamper 1, characteristics of a matrix surface of the stamper 1 are hard to be lowered, and the quality of a disk to be molded is good for a long time. Thus the stamper 1 of low wear resistance and low friction resistance is manufactured to achieve the realization of long life of the stamper 1, and a number of disks can be manufactured by one stamper 1 to achieve the reduction of the molding cost to a large extent.

Title: Joining method of steel pipe and copper pipe
Inventor: WAKABAYASHI YOICHI
IPC: B23K1/18
Filed: 1985-02-01
Abstract: PURPOSE:To reduce joining costs by fitting a steel pipe end sprayed with zinc and others on the outside surface of the pipe end into a copper pipe and pressure welding the fitted part by resistance heating. CONSTITUTION:Zinc power 2 is sprayed on the outside surface of an end part of the steel pipe 1 by spraying equipment. The end is fitted into an expanded part of the copper pipe 4 and the fitted part together with high resistance heating plates 7 and 8 are set between an upper and lower electrodes 5 and 6. The zinc powder is melted by resistance heat from the heating plates 7 and 8 by applying electric currents to the electrodes 5 and 6. The zinc reacts with copper and makes a Cu-Zn alloy phase, so that the fitted part is filled with a part of the alloy. Furthermore, the zinc diffuses into both the copper and steel side, so that the base metals 1 and 2 are joined through the alloy layer. This method reduces both material costs and labor to reduce joining costs.
