Title: Tape driving method
Inventor: UCHIDA RIYOUHEI
IPC: B65H23/18
Filed: 1980-09-30
Abstract: PURPOSE:To stabilize a reproducing picture, by adjusting the reduction gear ratio of a reel and a driving DC motor, and applied voltage of the motor, and making the tension of a tape almost constant. CONSTITUTION:When the product of rotational frequency of a reel and its torque is constant, the tension of a tape is kept constant. For instance, a curve C is drawn by setting the rotational frequency and torque to the horizontal axis and the longitudinal axis, respectively. The curve C makes the winding start and its end A and B, respectively, and is approximated by a straight line (a) passing through A and B. When the rotational frequency - torque characteristic of a driving DC motor is considered to draw a straight line (f), the rotational frequency - torque characteristic of the reel comes to draw a straight line (d) by governing the reduction gear ratio of the reel and the motor. Subsequently, when applied voltage of the motor is adjusted, the straight line showing the rotational frequency - torque characteristic of the reel moves in parallel, and is overlapped to the straight line (a) drawing the characteristic being approximate to the rotational frequcncy - torque characteristic of the reel, which makes the tension of a tape constant.

Title: Color proof making device
Inventor: KUSAYANAGI KOJI
IPC: G03B27/02
Filed: 1990-05-28
Abstract: PURPOSE:To securely bring a photosensitive material into close contact with a fixed board without preventing the carrier path of the photosensitive material by moving a squeezing roller for photosensitive material on the phtosensitive material by means of rotating it and permitting a cam member to separate the roller from the fixed board in an original position. CONSTITUTION:When the photosensitive material is inserted between the base plate 270 and the sucker 264 of a photosensitive material carrier part 200, the squeezing roller for photosensitive material 274 climbs on a cam plate 276 and a rotary shaft 274A is arranged toward the upper end of a long hole 272A. Thus, the photosensitive material 14 is prevented from being abutted on the roller 274. When the adsorption of the photosensitive material by the sucker 264 is removed, a moving member 202 once moves to a front part and if moves to return to an initial position. At that time, the roller 274 moves on the photo sensitive material by rotating. Thus, foam generated between the phtosensitive material and the fixed board 302 is squeezed and the photosensitive material is brought into close contact with the fixed board 302.

Filed: 1990-05-28
Abstract: PURPOSE:To improve heat resistance by using an aluminum target containing at least boron of 0.1 to 2 wt.% in deposition of an aluminum wiring layer by a sputtering method. CONSTITUTION:Boron is a heat-resistant material in itself, being in the same group with aluminum on a periodic table and being compounded with an amorphous metal, and it is an element obstructing a shift of a defect of a grain boundary and the like and being effective for making a crystal minute. By adding the boron to the aluminum, accordingly, a recrystallization temperature is raised and heat resistance is improved. Therefore, an aluminum target containing the boron is prepared and a thin film is prepared by a sputtering method. The boron content of the aluminum is preferably 0.1 to 2 wt.%. Addition of a hydrogen gas to a sputter gas, i.e. an argon gas, produces a remarkable effect on suppression of formation of a hillock.

Abstract: PURPOSE: To prevent a movable iron core from colliding with a stationary member and lengthen the life of a magnet, by forming a depression at the tip of a stationary member of an electromagnet, providing a specific relationship between the dimensions of this and a tapered part of the outer surface.  
     CONSTITUTION: Depression 9, which is to receive cylindrical movable iron core 5, is formed on stationary member 1, and tapered part 15 is formed on the outer surface of depression 9. We set w/W at 0W0.2 and l/L at 0.6W1.0, where the thickness of the iron core in the radial direction at the tip of tapered part 15 of stationary member 1 is represented by w, the thickness at the base part by W, the length of the iron core in the axial direction by l, and the depth of the depression in the axial direction by L. When movable iron core 5 advances to depression 9, the magnetic flux increases at a fixed rate within a fixed range of strokes and the attractive force is made constant. Hence, by setting the current at a fixed value, the force of spring 14 is balanced and iron core 5 is stopped, and thereby collision is prevented and the life is lengthened.
