Title: Magnetic bubble memory device
Inventor: INOUE HIROSHI
IPC: G11C11/14
Filed: 1981-12-15
Abstract: PURPOSE:To secure stopping and starting operation during bubble transfer by using a permanent magnet whose temperature coefficient is zero to positive, and generating a holding magnetic field to be applied to an element in a plane direction. CONSTITUTION:Permanent magnets 5 and 5' for bias magnetic field application are composed of materials having negative coefficients of temperature and then arranged over and under an element 4.

Title: Spring for restraining over-current
Inventor: NAKAMURA KAZUTO
IPC: F16F1/02
Filed: 1987-08-11
Abstract: PURPOSE:To reduce the effect of an over-current on the electrons of a beam by providing a number of through holes on the face of a clamp used for an electron-beam exposing device and dispersing the over-current.

Next, the heating rubber roll 6 is rotated so as to be synchronized with the transfer speed of the film 4 while transferring the film 4 for marking thermal transfer. The heating rubber roll 6 is pressure contacted against a metallic guide roll 8 through the film 4 for marking thermal transfer and the thermal transfer recording medium 2 at the starting position of the marking while the pressure contact of the roll 6 is released at the terminal position of the marking. Thereafter, the film 4 is peeled from the thermal transfer recording medium 2. As a result, a stripe type uniform detecting mark 11 may be transferred without stopping the transfer of the recording medium 2.
