Title: Lamp electrode device
Inventor: SUGIYAMA HIROSHI
IPC: H01J61/067
Filed: 1979-04-28
Abstract: PURPOSE:To reduce the wearing of an electrode and display the effect an auxiliary anode, by placing a longitudinal direction of the electrode toward the direction of a lamp tube axis. CONSTITUTION:A lead wire 9 at the preheat side is extended to support a filament 10 in such a manner as to permit its longitudinal direction to be positioned on the extension of a power side lead wire 11, that is, in the direction of a tube axis. A lamp current in the filament 10, because the tube central side end (connection side with the lead wire 9 at the preheat side) of the filament 10 is near the oppositely facing filament during the time of lighting, is routed and susceptible of flowing through said side end. This causes the current to flow in full length of the filament 10, resulting in the uniformly red heating throughout the overall length.

IPC: G11C17/18
Filed: 1983-03-30
Abstract: PURPOSE:To accelerate a mask memory and to reduce a chip area by simultaneously precharging the source and drain regions of longitudinally stacked mask ROM MOSFETs from a substrate. CONSTITUTION:A well 8 is epitaxially grown on a substrate 7 to form an electrically independent well. MOSFET T1-Tn, voltage applying electrode 9 are formed on the well 8.

Title: Two color electrophotographic method
Inventor: SUZUKI AKIO
IPC: G03G13/01
Filed: 1983-04-01
Abstract: PURPOSE:To obtain two kinds of electrostatic images having different potentials in a dark part and to enable development with two color toners by subjecting a photoconductor having the nature that the electrostatic charging voltage is increased by the previous exposure to two times of image exposure. CONSTITUTION:A photoconductive consisting of amorphous silicon, etc. doped with oxygen is uniformly electrostatically charged to maintain the surface potential at Vd. If the photoconductor is subjected to the 1st time of image exposure, the potential in the bright part where the light is irradiated decreases (1), but when the photoconductor is electrostatically charged again, the characteristic of the photoconductor changes as the light is applied once thereto and therefore the potential is higher potential Vl1 than the potential before the exposure. The potential in the dark part remains at Vd. When the photoconductor is subjected to the 2nd time of image exposure, the potential in the dard part region where the light is irradiated decreases to Vl2. A two color image is obtd. by using the potential Vd in the dark part where no light is applied in two times of the exposure as a developing bias and developing the image with two kinds of toners having different colors (for example, red and black) and having reversed polarities.
