Title: Lithographic exposure mask and its manufacture
Inventor: TEIMOSHII ARAN BURUNNAA
IPC: G03F1/30
Filed: 1994-12-16
Abstract: PURPOSE: To provide an optically improved phase shift mask structure for forming lithography exposure by selectively depositing silica into the openings of the patterns of polyimide or similar org. material from the liquid phase soln. of the silica in hydrofluorosilicic acid. CONSTITUTION: This optical improvement is executed by the deposition which is nearly anisotropically executed to form the deposition at a nearly uniform thickness. The deposition from the liquid phase is easily controllable and is capable of embodying the control to allow the prediction of a deposition rate at a high rate. Then, the impairment of the optical quality of the mask by other structures, such as etching stop layers, does not arise and the embodiment of the high phase shift structure is needed. The deposits of the phase shift material are nearly homogeneous. The deposition process from the liquid phase may be arbitrarily stopped and started. The mask depends on materials. The manufacture by nearly free process from the process limitation based on the materials is made possible.  The adjustment of the refractive index of the deposited materials by annealing is possible as well.

Abstract: PROBLEM TO BE SOLVED: To secure data of a memory cell by promptly changing a precharge voltage to a reference power source voltage when a differential voltage is generated between the precharge voltage of a bit line pair and the reference power source voltage. SOLUTION: When it is detected that a DRAM enters a retention mode, a signal PRA is not applied to a row decoder 12, thereby prohibiting an access to a memory cell C.

A sense amplifier-driving circuit 16 is activated by a control signal DRM1, so that a sense amplifier 13 is activated. An internal power source VDD is supplied to one bit line of a bit line pair and a power source VSS is supplied to the other bit line. Thereafter, the control signal DRM2 bar becomes an H level and the bit line pair is connected to a reference power source VPR. A voltage of each bit line pair and a voltage of the reference power source VPR are immediately turned to a half voltage of the internal power source.

Title: Making of bicolor copy electrophotographic copying machine
Inventor: JIEEMUSU DEII RIIZU
IPC: G03G15/01
Filed: 1989-12-05
Abstract: PURPOSE: To form a two-color output copy by cyclically scanning (passing) an original document corrected with fluorescent dye, that is, dystuff of a desired color once. CONSTITUTION: Light reflected on the original document 30 and passing a red filter, for instance, forms three electrification level patterns on a photoreceptor. At a black area part 30A, reflected light leaves an area part (high level) which is not discharged, and in a white background area part 30B, the reflected light forms a low discharge level. The light made incident on red fluorescent dye excites the dyestuff, and the incident light of the low level is emitted as the red light again. Therefore, it is added to the reflected red light so as to show apparent reflectivity higher than that of the white paper(effect 'whiter' than 'white color'). The emission in which the red is enhanced is discharged until the photoreceptor becomes a 3rd level lower than the white background, that is, the white level, and the electrification pattern of the 3rd level is developed.  Thus, two-color output copy is formed.

Title: Ink jet recording sheet
Inventor: OBAYASHI KEIJI
IPC: B41M5/50
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To improve density change due to oozing of dye or variation width of a color balance in the case of preserving for a long period at high humidity by setting opacity of an ink absorptive layer at a specific ratio or more, and increasing opacity of the layer provided at the side near a support higher than that of a side farther from the support. SOLUTION: The ink jet recording sheet comprises at least two ink absorptive layers at the same side of an opaque support so that opacity of the overall layer becomes 20% or more. The opacity is brought by light scattering of the layer provided at the side near the support. The opacity of the layer provided at the side farther than the support must be lower than that of the layer provided at the side near the support. Accordingly, the ink jet recording sheet can be improved for density change or variation width of color balance due to oozing of dye even when it is preserved for a long period even at high humidity after printing.
