Title: Clock timing control circuit
Inventor: TOMA TAKASHI
IPC: G11B20/10
Filed: 1987-09-18
Abstract: PURPOSE:To always obtain optimum phases of a clock and data by comparing a phase difference between a demodulated signal and a signal latched by a clock. CONSTITUTION:A demodulated signal is applied to a resonator 2 through a gate 1. The resonator 2 extracts a clock component from the digital signal and a comparator 3 shapes the extracted component to form a reference input to a PLL 4. The demodulated digital signal and the output of a latch 5 are inputted to a phase comparator 6 and an error signal corresponding to a phase difference between two input signals is outputted. The output is smoothed by a low pass filter 7, amplified by an amplifier 8 and its output is applied to the resonator 2 as a control voltage. Consequently, the phase difference between the input data of the latch 5 and the clock is always set up to 90 deg..

Title: Pattern forming method
Inventor: HAYATA YASUNARI
IPC: G03F7/20
Filed: 1985-10-23
Abstract: PURPOSE:To prevent reduction in the sensitivity of an X-ray sensitive resist film formed on a body for transfer by laminating a Langmuir film on the resist film and carrying out exposure with X-rays. CONSTITUTION:Exposure is carried out with characteristic X-rays Mo-L(lambda=5.4Angstrom )1 from a rotating anticathode type X-ray source using Mo as a target. An NPR resist 4 is applied to a wafer to 1mum thickness and prebaked at 80 deg.C. Layers of omega-tricosenoic-acid are laminated as a Langmuir film 3, and proximity exposure under the presence of air between a mask and the wafer and development with a developing soln. for 3min are carried out. When four or more layers are laminated, the total thickness is made equal to the residual thickness of a film in helium and the effect of oxygen can be eliminated. Since the film 3 is a very thin film called a four-molecular layer, the attenuation of X-rays is negligibly small and uniform lamination can be carried out. Thus, reduction in the sensitivity of the resist due to oxygen in the air can be prevented.

Title: Magnetic recording medium
Inventor: KATSUKI TOSHIYUKI
IPC: G11B5/65
Filed: 1986-10-03
Abstract: PURPOSE:To permit uniform reproduction output by forming a magnetic layer to the film thickness smaller nearer the inside peripheral part along the radial direction of a medium so that the larger coercive force is obtd. in the inside peripheral part than in the outside peripheral part. CONSTITUTION:The magnetic layer 13 is formed to the film thickness smaller nearer the inside peripheral part 15 along the radial direction of the magnetic recording medium. The magnetic layer 13 is formed by means such as sputtering and vapor deposition. The coercive force (Hc) of the magnetic layer 13 is thereby changed and the larger coercive force is obtd. in the inside peripheral part 15 where the film thickness is small than in the outside peripheral part 16. The reproduction output in the inside peripheral part 15 of a floating type magnetic head is increased by increasing the coercive force (Hc) in the inside peripheral part 15. The maintenance of the high reproduction output which is high in the outside peripheral part 16 equally high in the inside peripheral part 15 as well is, therefore, permitted. The uniform reproduction output is thus obtd. even if the floating type magnetic head exists in any position between the outside peripheral part 16 and inside peripheral part 15 of the magnetic recording medium.

IPC: B65D61/00
Filed: 1990-09-05
Abstract: PURPOSE:To permit a side frame to be folded easily and safely by a method wherein the lower end of a side frame is rotationally mounted to a base frame and a rotation stopping mechanism is provided in contact with the inner side faces of the side frame to hinder its rotation. CONSTITUTION:Since the operating members 92 of a rotation stopping mechanism 90 are in contact with the inner surface of a support 30 at the place of mounting a side frame B to a base frame A, the rotation of the side frame B is hindered and supported in a vertical position without turning down. The side frame B, since a wing bolt 18 is attached thereto, is more securely held in place. The wing bolt 18 is loosened and removed and the operating members 92 of the rotation stopping mechanism 90 are simultaneously turned upwards against the force of a spring on the left and right side faces of the side frame B to be moved out of contact with the support 30, so that the support 30 can be rotated. In this way the support 30 and the side frame B are turned down inwards to permit the side frame B to be folded until it becomes parallel to the base plate A.
