Title: Semiconductor device memory
Inventor: FURUYA KIYOHIRO
IPC: G11C11/401
Filed: 1987-03-06
Abstract: PURPOSE:To effectively use the periphery of a memory cell for capacity forming regions and to contrive to improve the yield and the reliability of a memory by a method wherein the memory is constituted in a structure, wherein one word line and two bit lines are passed through the region of the one-bit memory cell. CONSTITUTION:When a word line 7a is given a high potential, a back-to-back bit lines are composed of Al circuits 6c and 6b and so on. By such the constitution of a memory, a memory cell becomes long in the direction of the word line and an allowance for forming isolation oxide films 2 between transfer gates 11 and the periphery of the memory cell is generated. Therefore, even though a capacity for information charge storage is formed on the side surfaces of the memory cell using all the periphery of the memory cell as grooved isolation regions 12, there is no need to etch a polySi layer 3 on the bottoms of grooves. Accordingly, the periphery of the memory cell can be effectively utilized in an easy production process, the capacity for information charge storage is secured even in the shallow grooves and the yield and the reliability of the memory can be improved.

Title: Method of calming operation of dot printer
Inventor: TEIMU BUARENTAIN ANGUSUTO
IPC: B41J2/485
Filed: 1987-03-10
Abstract: Method and apparatus for quieting the operation of a dot matrix printer by logically dividing the data to be printed among timed spaced printing passes. A matrix of data to be printed is stored in a memory. A slice of data is selected from the stored data and the number of dots to be printed simultaneously is reduced by logically allocating the data in each slice among complementary submatrices. Each submatrix of data is printed substantially aligned with each other submatrix in two passes of the print head across the print medium to represent the entire selected slice of data. Noise reduction is achieved by reducing the number of data dots simultaneously printed at each print location

Title: Pulse power supply
Inventor: SEKI HIROBUMI
IPC: H02M9/04
Filed: 1990-03-07
Abstract: PURPOSE:To enhance efficiency by equalizing the line impedance of current, flowing from a capacitor through a saturable reactor to a load, to a load impedance and feeding energy to a discharge lamp while matching the impedance. CONSTITUTION:When a current flows slightly through a preionization electrode 16 upon closure of a switch 3, a voltage approximately same as the voltage to be applied on a capacitor 10 is applied onto a saturable reactor 14 thus saturating the saturable reactor 14. Since a capacitor 12 has a sufficiently lower capacity than the capacitor 10, energy stored in the capacitor 10 is partially transferred to the capacitor 12. At the time point when the applied voltage of the capacitor has peak value, a discharge lamp starts discharging while simultaneously the saturable reactor 10 is saturated. Since energy can be injected from the capacitor 10 into a load while matching the impedance, a laser can be oscillated with high efficiency.

Abstract: PURPOSE:To secure transmissivity in the ultraviolet-ray and far-ultraviolet-ray ranges and to obtain high resolution by coupling two couples of catadioptic optical systems consisting of a concave and a convex mirror member and a phase correcting member with each other and thus constituting one catadioptic optical system, and obtaining principal refracting power by a reflection system. CONSTITUTION:A catadioptic optical system I on an object point side consists of a convex mirror 2, a concave mirror 3 which has an opening in the center, and a phase correcting plate 4, and an object 1 of projection is placed on the focal plane F of the optical system I. A catadioptic optical system II on an image point side consists of a phase correcting plate 4', a concave mirror 5 which has an opening in the center, and a convex mirror 6. Light emitted from one point of the object 1 of projection passes through the opening of the concave mirror 3 and is reflected by the convex mirror 2 toward the object 1 of projection and then reflected again by the concave mirror 3 to pass through the phase correcting plate 4. The light having passed through the phase correcting plate 4 becomes parallel light, which impinges on the phase correcting plate 4 and is reflected by the concave mirror 5 toward the object 1 of projection. Then, the light is reflected again by the concave mirror 5 to the opposite side from the object 1 of the projection and passes through the operating of the concave mirror 5 to form a projection image 7 in a plane perpendicular to a reference axis behind the concave mirror 5.
