Title: Magnetic bubble domain enlarging device
Inventor: YAMAGUCHI NAKAHIKO
IPC: G11C11/14
Filed: 1982-10-15
Abstract: PURPOSE:To obtain a magnetic bubble domain enlarging device improved in transfer characteristic of magnetic bubble by arranging unit pieces of basic pattern that constitute the magnetic bubble domain enlarging device so that the length of the unit pieces becomes alternately long and short in the direction of magnetic bubble transfer. CONSTITUTION:A basic pattern 30 that constitutes a magnetic bubble domain enlarging device 1 is so formed that a total length L of the pattern in a direction P of a magnetic bubble transfer is about 10-20 times as long as the diameter of a magnetic bubble, and the length of a shorter unit piece 10 or 11 is about 1/2-4/5 of the length of a longer unit piece 12 or 13. The pattern axis of the basic pattern 30 is made to coincide with the direction that intersect the direction P of the magnetic bubble transfer. At the same time, shorter unit pieces 10, 11 and longer unit pieces 12, 13 are so arranged at specified intervals that the length in the direction P of the magnetic bubble transfer becomes alternately long and short. Thus, a magnetic pole can be strengthened by arranging alternately shorter unit piece 10 or 11 corresponding to weak shoulder parts 8, 9 of the magnetic pole of the basic pattern 3 which have so far been weak points.

Title: Copying machine provided with copy pattern memory function
Inventor: KURIHARA SUSUMU
IPC: G03G15/00
Filed: 1989-07-12
Abstract: PURPOSE:To prevent the double usage of the identical registered numbers and to prevent the identical patterns from coexisting by informing of the double usage by the use of display, etc., when a registered number already used is inputted. CONSTITUTION:In the case of newly registering a copy pattern in a nonvolatile memory 11, a write mode is selected by depressing a job memory key 5 twice. Then, a CPU 10 instructs a power source driving circuit 8 to flicker a light emitting diode D2 to inform of the write mode. When the registered number of the copy pattern which is going to be written is inputted by ten keys 1, the CPU 10 judges whether the copy pattern of the inputted registered number has been already registered in the memory 11. When the number has been already registered, the diode D2 is flickered so as to inform an operator of the double usage, and the double write and the coexistence of the identical pattern are prevented.
