Title: Semiconductor nonvolatile memory
Inventor: TANAKA TOSHIAKI
IPC: G11C16/06
Filed: 1992-05-29
Abstract: PURPOSE:To provide the device with the large number of times of rewriting by setting the voltage values of the erasing voltage and the writing voltage of a memory element as optimum values different from each other, respectively. CONSTITUTION:A Zener diode for erasure 25, a changeover circuit block 21 thereof, a diode for writing 27 and a changeover circuit block 23 thereof are provided between a power source voltage line 11 and a -VPP line 13. When the memory element is to be erased, after changing a erasing program signal PG1, from the power source voltage 5V to a reference potential 0V, the -VPP line is lowered to -VPP from the reference potential. The -Vpp line becomes -3.5V of the Zener potential of the Zener diode for erasure 25. At the time of writing, a signal PG2 is changed from 5V to the reference potential of 0V, the -VPP line 13 changes from 5V to 0V and the -VPP line is dropped from 0V to -VPP. The -VPP line becomes to be 4.0V as that of the diode 27.

Title: Plural original batch copying machine
Inventor: SUMITA HIROYASU
IPC: H04N1/387
Filed: 1993-06-30
Abstract: PURPOSE:To form an image of a picture of plural originals onto one transfer paper in the batch without reading the original of white paper when number of originals is less than a predetermined number by providing an integrated number setting means, a picture memory, an original number setting means and a control means controlling the image forming means to form an image in a specific case. CONSTITUTION:When an integrated copy key on an operation section 611 is depressed, entry of an integrated copy key sheet number key displayed on the operation section 611 is awaited and number of integrated copies is decided, a designated integrated sheet number P is reserved. The operator publicates a picture drawing request for an original sheet number entry menu to draw a pattern to enter an original sheet number to be copied. When the original sheet number is decided, the designated original sheet number O is reserved. Since output is executed even when the integrated sheet number P differs from the original sheet number O, an image is formed altogether on one transfer paper without reading a white original by allowing the user to set the original sheet number O less than the integrated sheet number.
