Title: Magnetic recording and reproducing device
Inventor: HANEKAWA KIYOSHI
IPC: G11B5/012
Filed: 1982-06-16
Abstract: PURPOSE:To perform continuous recording/reproducing actions with a miniature recording/reproducing device, by sliding the axial core of a rotary head to a revolving magnetic recording disk and in the diameter direction while the rotary head is turned with a slant in the diameter direction of the recording disk. CONSTITUTION:A magnetic recording medium 1 is revolved by a motor 2 around a shaft 102 rectangular to a magnetic recording plane 101. A rotary head 3 is set so that the rotary shaft 6 of the head 3 crosses a segment 103 passing through the center of the medium 1. The head is then revolved by a motor 4 and moved by a moving mechanism 5 in parallel to the diameter direction (a) of the medium 1. As a result, the signals can be recorded continuously and spirally to the head 3 to the medium 1 with a miniature magnetic recording/reproducing device. A continuous reproducing action is also possible with an operation adverse to the recording action.

Title: Sheet width detector
Inventor: SUGANO TSUYOSHI
IPC: B21B37/22
Filed: 1985-05-17
Abstract: PURPOSE:To perform a highly reliable control of the incorrect warpage of a rolled material by accurately detecting the change in the position in vertical direction and the sheet width both being of the rolled material. CONSTITUTION:Image sensor cameras 12 mounted on the right-hand and left- hand sides above the outlet side of a rolling mill toward which a rolled material 11 passes detect the sheet width of the rolled material 11 through slitted bodies 14. At this time, the cameras 12 measure the lengths Xd and Xw of the marginal portions of the slitted bodies 14 which are not shielded by the rolled material 11. By taking both the marginal portions of the slitted bodies 14 as detection references, the sheet width at a measuring point, determining the distance L between right and left detection reference points of the slitted bodies 14, is obtained from the values Xd and Xw detected by the cameras 12. Sheet position signals thus obtained are connected to a processor 17, which performs calculation and decision and the sheet width, a sheet misalignment quantity and direction are obtained. The processor 17 is connected to a hydraulic jack or the like via a hydraulic pressing controller 19. By a servo circuit thus constituted, the sheet discrepancy between the rolled materials 11 and 11' can be controlled to be finally reduced to zero.

Title: Data processing circuit
Inventor: SUEMATSU TOSHINARI
IPC: G06F21/14
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To apply a data processing circuit to a general-purpose computer by generating the relative address information on every address against the head address and securing the corresponding secret data based on the relative address information. SOLUTION: A CMP 1 has its proper secret key Ksmp. An offset register receives the fetch signal s4 outputted from a CPU 2, fetches the head address data showing the head position of data when the CPU 2 performs the read/write operations to a main memory 21 to stores the head address data and then outputs these data to a scramble code generator 6. Meanwhile, the relative address information on every address is generated against the head address and the corresponding secret data are secured based on the relative address information. The generator 6 generates a scramble code F(Re) from the head address data and the address data inputted from an address bus 16 and outputs the code F(Re) to an adder 11 via a signal path 13.

Title: Steel tube having glass lining
Inventor: ANDO AKIRA
IPC: C23D5/04
Filed: 1988-04-28
Abstract: PURPOSE:To prevent the occurrence of defects such as cracks in a glass tube on the inside of a steel tube even when external force is applied to the steel tube, by interposing a specified metal layer between the inner wall of the steel tube and the peripheral surface of the glass tube when a steel tube having a glass lining on the surface of the inner wall is produced. CONSTITUTION:When a glass tube 2 as a lining is formed on the surface of the inner wall of a steel tube 1, a layer 3 of a metal such as Cu, Au or Ag is first formed on the surface of the inner wall, the glass tube 2 is formed on the layer 3 and the resulting glass lined steel tube is heated at 600-800 deg.C. The metal layer 3 does not melt or bond to the surface of the inner wall of the steel tube 1 at the heating temp. but the peripheral surface of the glass tube 2 melts and bonds to the layer 3, so external force applied to the steel tube 1 does not propagate to the glass tube 2 and the occurrence of defects such as cracks in the tube 2 is prevented.

Abstract: PURPOSE:To improve operability, by moving auxiliary hoppers to discharge receiving positions from measuring hoppers and positions, which are deviated from the receiving positions. CONSTITUTION:Auxiliary hoppers 12 are provided in correspondence with measuring hoppers 11 in a combination scale. When the hopper 12, which is selected in combination, discharges a material and becomes vacant, a measured material is discharged from the upper hopper 11. When the hopper 11, which is not selected in combination, is located above the hopper 12, in which a material that is not selected in combination is contained, an air cylinder 13 is actuated and the hopper is moved to 12a shown by an imaginary line. Then the material in the hopper 11 is discharged. When the hopper 12, which is selected in combination, is located under the hopper 11, which is selected in combination, the discharge operations are performed by both hoppers. The material in the hopper 11 is discharged on a conveyer 14 through the hopper 12. Since one half the number of the hoppers, which take parts in combination, is the measuring hoppers, the number of the measuring systems is few. Since the material is inputted to the measuring hoppers, number of input positions becomes few, operability is good and costs can be reduced.
