Title: Formation of film from micro-fine particle
Inventor: HAYASHI CHIKARA
IPC: B05D7/24
Filed: 1982-11-10
Abstract: PURPOSE:To form the film of micro-fine particles having excellent strength, predetermined shape and thickness on the surface of a base, by mixing the very fine particles with carrier gas, and spraying the mixture through a small-size nozzle onto the surface of the base. CONSTITUTION:A proper amount of micro-fine particles (a) such as Ni or Co is received in a vessel 1, while gas, e.g. Ar or He, or the like is injected as carrier gas (b) therein to maintain the superfine particles (a) under a floating condition. The mixture is then sprayed from the top end of a very small-size nozzle 6 onto the surface of a base 7. Thus, the very fine particles (a) are pressed onto the surface of the base 7 and adhered and accumulated thereon by the pressure of the gas, to form a dense film of proper thickness composed only of the very fine particles.

IPC: G06F3/153
Filed: 1989-07-28
Abstract: PURPOSE:To speed up character display operation by providing a character input means and a comparing means and rewriting a frame memory only when the comparison result indicates a dissidence. CONSTITUTION:A control part 100 is equipped with a character code control means 1, a comparison control means 7, a transfer control means 8, and a display control means 9. The character code control means 1 is informed of key input and performs conversion into an address of a display code memory 2. The comparison control means 7 waits for the key input to end and the comparison control means 7 compares character codes with character codes in the same area of a code memory 6, character by character; when the comparison result indicates a dissidence, a dissident address is received by the display control means 9 and data is read out of the memory 2 and written in the same address of the memory 6. In response to the end of writing, the transfer control means 8 is informed of the address and the processing is finished. Thus, only characters which are really rewritten are written in the frame memory 4 on a bit basis to reduce unnecessary memory access and improve the processing speed.
