Abstract: PURPOSE: In a tape transfer apparatus having supply and take-up reels and buffers on supply and take-up sides, to shorten the tape transfer time by increasing or decreasing tape transfer speed depending upon a position of the tape in the buffer.  
     CONSTITUTION: A tape transfer apparatus includes supply and take-up reels 1, 2 driven by motors 3, 4, buffers 5, 6 positioned on supply and take-up sides and a tape feed mechanism 12. The buffers 5, 6 are provided with tape position sensors 15, 16, 17, 18 for detecting the least upper and lower limit positions of a tape loop, and tape loop position detecting circuits 7, 8, wherein the motors 3, 4 are controlled according to output of the circuits 7, 8. The output of each sensor 15W18 is sent to a tape feed control circuit 14 through a sense circuit 9. When the tape loop is positioned in the center of each buffer 5, 6, the feed mechanism 12 accelerates speed, and when the tape loop reaches the least upper or lower limit position, the feed mechanism 12 decreases speed.

Title: Refractive index measuring apparatus
Inventor: KASHIMA GIYUU
IPC: G01N21/41
Filed: 1982-07-19
Abstract: PURPOSE:To enable a local measurement of refractive index handily by a method wherein light signals of varied wavelengths enter one end of an optical fiber and reflected lights from a contact end face are detected with the other end thereof contacting material to be measured. CONSTITUTION:Optical pulses with wavelengths of lambda1-lambdan enter one end of an optical fiber 2 through an optical directivity connector 3 and the other end thereof is brought into contact with an object 4 to be measured in a liquid. When entering, the optical pulse is reflected on the boundary with the objet 4 being measured, the reflection level thereof is detected with a detector section 5 through the connection 3 and then, the refractive index (n) is measured from the reflection level R thus obtained. But as the same reflection level corresponds to two refractive indexes, when the reflection level of light is R1 at the wavelength changed to lambda1 the refractive index is n1 or n2 and when the reflection level is R2 at the wavelength of lambda2, the refractive index is n1. The use of many wavelengths can improve the identification accuracy thereby enabling a local measurement of refractive index simply.

Title: Magnetic disk device
Inventor: ENDO KENICHI
IPC: G11B33/14
Filed: 1986-05-30
Abstract: PURPOSE:To prevent the destruction of a magnetic fluid seal due to the pressure difference between a magnetic disk device inside and atmosphere caused by the adhesion of an antistatic bag or the like at transportation mainly by providing a step to the device outer face of a part having a breathing filter. CONSTITUTION:The structure is adopted that the pressure difference with external air is eliminated through a breathing filter 12 and a breathing hole 13 placed at the inside of a shield chamber or a base frame 11. That is, even if a pressure difference is caused, the adhesion of the antistatic bag onto the entire face of the breathing filter is prevented because of the step difference 14 provided at the outer face of the device. Since the step difference 14 is continuous up to other outer face 15 in contact with the breathing filter installing face, even if the antistatic prevention bag is adhered to the step difference upper face at the outside of the breathing filter installing face, since breathing is attained at the face led to the step 14, no pressure difference is caused.

Abstract: PURPOSE:To measure the surface form and surface accuracy at high speeds by a method wherein interference fringes are formed for a measuring part parallel to one of principal radial lines orthogonal to each other on a toroidal surface and the measuring part is scanned in parallel to the other principal radial line thereby to measure the whole surface. CONSTITUTION:The oscillating intensity of interference fringes 11 formed on an image sensor 10 is obtained as a sine analog signal via an amplifier 12. High frequency components of this analog signal, not smaller than 1/2 of the sampling frequency at the time of the A/D conversion, are removed by anti- aliasing filter 13. Then, the signal is decomposed to a digital signal through an A/D converter 14. The digital signal is through an A/D converter 14. The digital signal is input to an operation circuit 15, and Fourier transformed at high speeds in an FFT circuit 16. A spectrum to the spatial frequency is obtained in a spectrum extracting circuit 17. An inverse FFT circuit 18 performs an inverse Fourier transform. A phase calculating circuit 19 obtains the phase to the wavelength. The thus-obtained surface data is stored in a memory 20 and analyzed with the surface accuracy data 21.
