Title: Erasing head and manufacture of erasing head
Inventor: UESHIMA KEISUKE
IPC: G11B5/127
Filed: 1988-04-15
Abstract: PURPOSE:To improve the erasing effect of a signal by causing the tape contact length of a front core part located at an upstream side to be shorter than 1.2mm as to the traveling direction in the core parts to form a gap part. CONSTITUTION:When a tape 5 travels in an arrow X1 direction, the core part at the upstream side is made into a core part 11. At the time of executing the traveling at the traveling speed of the tape 5 from 9.5cm/s to 76.2cm/s, a tape contact length l1 on the contact surface of the core part 11 is selected to be 1.2mm or below. For the case where the traveling direction of the tape 5 is changed, it is preferable that a tape contact length l3 of a core part 13 is also selected to be 1.2mm or below. On the other hand, a tape contact length l2 of a core part 12 is decided by materials to consider the magnetic characteristics of the core parts 11, 12 and 13 and by a real magnetic flux density. By such an erasing head, the erasing effect at the time of the erasing action of the signal recorded onto a recording medium can be improved.

Inventor: MASUDA SHINICHI
IPC: G01B11/24
Filed: 1989-04-13
Abstract: PURPOSE:To shorten the time for image process by radiating a linear beam to the position of a reference line on the surface of an object to be tested, forming an image of a beam radiated to the surface of said object from a position different from a light source, and scanning the obtained images for comparison of the luminance data by a scanning unit. CONSTITUTION:An object 14 to be tested is fixed on an XY table 18 which is movable in X, Y directions. A high speed external synchronizing circuit 22 forms a scanning signal which scans an image of the testing surface 14' taken into a pick-up part 20. A TV camera of the pick-up part 20 is scanned in a horizontal and a vertical directions by the scanning signal, whereby a predetermined image signal is obtained. An electric signal indicating the surface shape of the object 14 obtained by the pick-up part 20 is, through an A/D converter 24, fed to a gravity measuring part 26. Then, the luminance data obtained through scanning are sequentially compared every scanning line in the measuring part 26. Thus, the maximum luminance position of the image is detected. From the data of the maximum luminance position, the data of the height of the position of a reference line X1 on the surface of the object 14 is measured.
