IPC: H01L29/792
Filed: 1987-05-29
Abstract: PURPOSE:To prevent mis-write by increasing a potential of a selection gate electrode of a non-selection cell with no charge injected thereto at the program higher than the potential of a selection gate electrode of the selection cell to which an electric charge is injected thereby using a potential difference so as to select the cell. CONSTITUTION:The selection gate electrode voltage of a non-selection cell with no electron injected thereto at program is increased more than selection gate voltage of the selection cell so as to decrease the potential difference between the selection gate electrode of the non-selection cell and the floating gate electrode. Thus, the electric field fed between the selection gate electrode and the floating gate electrode is decreased. Thus, the injection of electrons through tunneling from the selection gate electrode to the floating gate electrode is prevented.

Title: Cpu external access bus system
Inventor: NISHIMURA TADAO
IPC: G06F13/38
Filed: 1989-05-26
Abstract: PURPOSE:To decrease the number of interface lines set between a CPU mounting part and a part to receive an access without reducing the capacity of an access space by multiplexing both address and data buses. CONSTITUTION:When an address is transferred to a part 200 to receive an access, a CPU 101 makes the multiplex bus sequence control information show an address cycle and sends an address to the part 200 via a multiplex bus 4. When the data are written, the CPU 101 makes the multiplex bus sequence control information show a data writing cycle and sends the write data to the part 200 via the bus 4. Then the part 200 transfers the data to a CPU mounting part 100 via the bus 4 since the read timing is instructed when the multiplex bus sequence control information shows a data reading cycle. As a result, the number of interface lines can be decreased even if the address space of the part 200 is large.

Abstract: PURPOSE:To prevent moire fringe from occurring by making the extending direction of plural projecting lines of a phase grating coincide with the ridge direction of the lenticular lens of a transmission type screen. CONSTITUTION:The phase grating 4 having plural projecting lines 16 arranged in parallel with a direction perpendicular to an optical axis is provided between a liquid crystal cell 1 and the transmission type screen 6, and the extending direction of the plural projecting lines 16 is made to coincide with the ridge direction of the lenticular lens 12 of the screen 6.
