Title: Graphic display unit
Inventor: HOSOKAWA NOBORU
IPC: G09G5/34
Filed: 1983-04-08
Abstract: PURPOSE:To renew the screen simply by rewriting a memory of the address at both ends thereof with a means of delaying a horizontal synchronization signal and a display timing signal by a dot unit. CONSTITUTION:A roll mode circuit 12 is provided to perform a roll mode. When a shift register 9 is shifted according to a dot pulse D, a series input signal is outputted in delay from a cycle unit of the pulse D at the position of the output. These signals are processed with a data selector 10 to output one of inputs 1- 8. As the selector 10 selects a signal complying with a select signal outputted from a latch 11, a display timing G and a horizontal synchronous signal H can be delayed to 0-7 dot simply in a dot cycle unit by rewriting the latch 11. When the timing G' and the signal H' thus shifted are inputted into a video control 6, a video signal is synthesized and thus, the contents of the memory data displayed on a video monitor screen 7 can be shifted to one dot unit.

The substrate is dehydrated by heating and thereafter a film of carbide or nitride of Ti, Zr or Hf, BN, SiC or the like is formed to about 1.5mu thickness thereon by high-frequency ion. The surface is buffed by using the alumina abrasive grains and is then heat-treated for about 2hr at 350 deg.C. An alpha-Al2O3 film is formed with Al2O3 as a vapor source on the alumite film after buffing. The magnetic disk or the like having excellent resistance to scratching and excellent surface smoothness is thus obtd.

Filed: 1982-04-14
Abstract: PURPOSE:To enable the control of bubble chip of different type, by using a programmable logic array which feeds the output of an OR array back to an AND array via a flip-flop, etc. CONSTITUTION:The address information 103 of a request signal within a bubble memory is processed by an AND array and via the 1st programmable logic buffer (PLA) 101. The output of the AND array is processed by an OR array. Then a part of the OR array output is applied to an FF group to produce an address coincidence output 104. The output 104 is fed back to the AND array. The working periods of a generator, a replicating gate, etc. are counted at and after the generation of the output 104.
