Title: Magnetic recording medium
Inventor: MATSUMURA SHINICHI
IPC: B29C55/14
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To control deformation of a magnetic recording medium to reduce erroneous tracking and error rate by smoothing a difference between the maximum and minimum values of double-refractive index in the full direction within the surface so that it becomes less than the particular value, using a biaxial orientation ethylenetelephthalate film as the non-magnetic carrier on which the magnetic layer is coated. SOLUTION: Unextended polyethylenetelephtalate film is heated higher than the glass transition point for extension up to 2 to 5 times in the vertical and horizontal direction to realize biaxial orientation. It is then thermally fixed by the stentering method to make smooth the surface roughness to 1 to 7nm. Thereby, a non-magnetic carrier is formed and a difference between the maximum and minimum values of double-refractive index in the full direction within the surface thereof is set to 12×10<-3> or less. Here, when the surface roughness becomes 7nm or more, it gives influence on the roughness of magnetic layer provided on the carrier. Thereby, spacing loss become large and electro-magnetic conversion characteristic is lowered to increase the error rate. Moreover, when roughness is 1nm or less, a trouble may occur in the winding or carrying by rolls in the coating process.

IPC: G05D16/16
Filed: 1987-02-25
Abstract: PURPOSE:To improve the response of a closed valve by communicating a path opening to the wall of a piston room to the secondary side excepting the piston front part and forming a proper area of said path into a fine hole. CONSTITUTION:For a pressure reducing valve, a path 22 opens to a wall 20 of a piston room 7a at its single end and opens to a path 8 at the other end. The open part of the path 22 set at the side of the room 7a is formed into a fine hole 21. At the same time, the room 7a is connected to the secondary side via both paths 22 and 8. Then, the secondary side of the pressure reducing valve rise up to a set level while a main valve 3 is kept open. Thus a pressure setting part 6 serving as a part working in response to reception of the pressure is actuated together with a diaphragm 5. As a result, a pilot valve 4 is opened to stop the supply of the primary side high pressure steam to the room 7a via a path 9, the valve 4 and a path 17. Then a piston 7 moves back in response to the flow rate supplied to the secondary side from the room 7a and the valve 3 is closed. Thus, the response of the valve 3 is improved when it is closed by a closing action of the valve 4.

Filed: 1990-02-26
Abstract: PURPOSE:To prevent distortion of recorded data and occurrence of color shift by arranging legs which support a frame at points on the bottom of an enclosure corresponding to an area other than a defined area as an area for recording. CONSTITUTION:A leg 20A and a leg 20B on a side where a recording head scan mechanism is incorporated among other legs 20A to 20D supporting a frame 1 are arranged right below a carriage guide shaft 13. Consequently, a common area to the left of a vertical surface (X1 to X1 surface) including the shaft core of the guide shaft 13 takes the form of a cantilever beam supported through legs 2A, 2B. If an ink jet recording device of this constitution is mounted on an installation surface 30 where an obstacle 31 is present, for example, and one 20C of the legs rides over the obstacle 31, the frame 1 at the right of the X1-X1 surface becomes flexible, while the frame 1 at the left of the X1-X1 surface becomes little flexible. Subsequently, the position of the recording head 10 which scans a recording sheet 3 held by a platen 8 in the area at the right of the X1-X1 surface changes due to the deflexion. Therefore, the prevention of occurrence of a distortion in print or an image or color shift is ensured.
