Abstract: PURPOSE:To shorten a turnaround time, and to reduce the occupying area of a memory cell by selecting the state of a memory according to a short-circuit or non-short-circuit by a metallic wiring layer between a source and a drain by using series type memory-cell constitution using a MIS field-effect transistor. CONSTITUTION:Since nonselective word lines 31 are all kept at a high level on the reading of informations, nonselective memory cells are all brought to a conductive state. Since a memory cell transistor 36 for a memory cell connected to a word line 31 selected is brought to a nonconductive state, on the other hand, the memory cell is brought to the conductive state when a source and a drain are short-circuited by a metallic wiring layer 35, and brought to a nonconductive state when they are not short-circuited. Since memory cells belonging to one line are connected in series, a section between a bit line and a grounding line is brought to the nonconductive state when the memory cell connected to the word line 31 selected is brought to the nonconductive state. When the memory cell connected to the word line 31 selected is brought to the conductive state, on the other hand, the section between the bit line and the grounding line is also brought to the conductive state. Accordingly, informations are read.

Title: Road planer
Inventor: YAMAGISHI TAMIO
IPC: E01C23/12
Filed: 1994-06-21
Abstract: PURPOSE:To turn the cut end of a paved surface to a coarse slope surface and enhance the consolidation of new and old pavement materials by fixing a group of bits so that the elevation of a bit at the tip may be increased gradually at the central part from a lateral end of a drum and fixing the remaining bits with a spot slightly deviated to the central part so that they may reach the maximum height. CONSTITUTION:A road planer A is halted at a cutting starting position of a road surface where a drum 1 is lowered to the road surface while the drum 1 is being driven rotatively. Bits 4 at the central part of the drum 1 are placed into contact with the road surface at first and then cutting is started. Then, the road surface is cut down while the bits 4 close to the lateral side of the drum 1 are placed into contact with the road surface one after another, thereby widening a cutting width gradually and forming a slope at the cutting end. After the drum 1 is lowered to a specified depth of the paved area of the road surface, the road planer is moved forward slowly so that a pavement material is planed with the bits 4 in a continuous mode so operated as to push out the scraped scraps of the pavement material together with a scraping plate 5 in the advancing direction, thereby proceeding with cutting work of the road surface. This construction makes it possible to turn the cutting end into a slope and cut the road surface with the bits 4 so as to produce a coarse surface and enhance the consolidation at the joint area with a new paved road surface.

Title: Semiconductor integrated circuit
Inventor: KANEKO KAZUO
IPC: H01L23/52
Filed: 1990-05-28
Abstract: PURPOSE:To prevent disconnection due to corrosion by a method wherein an interruption wiring put in a floating state whereon no potential is impressed is disposed on an insulating film between a low-potential-side wiring and a high-potential-side wiring. CONSTITUTION:With bias impression on a low-potential-side wiring 2 and a high-potential-side wiring 3, movable ions in an electrolyte solution are to move respectively. An interruption wiring 5 is disposed between the low-potential-side wiring 2 and the high-potential-side wiring 3 and the movable ions can not move through an interface between the interruption wiring 5 and an insulating film 1, since the adhesion of this wiring to the insulating film 1 is made stronger than that of a passivation film 4 to the insulating film 1 by annealing. The surface of the interruption wiring put in a floating state is made passive by an oxide film, and therefore an electric reaction can hardly occur. Therefore, the low-potential-side wiring 2 and the high-potential-side wiring 3 are put in a state of being insulated from each other by the interruption wiring held by a passive giobsite in the electrolyte solution. Accordingly, electrolytic corrosion is suppressed and the deterioration and disconnection of the wirings 2 and 3 can be prevented.

Title: Automatic pressure reducing mechanism of four-cycle internal combustion engine
Inventor: IGARASHI MASASHI
IPC: F02D15/00
Filed: 1986-06-17
Abstract: PURPOSE:To improve a starting property by slightly lifting up an exhaust valve by means of a pressure reducing cam at the time of compression stroke on starting an engine, and allowing part of compressing pressure to escape and reducing an inputted starting torque. CONSTITUTION:When a driving timing sprocket 24 and a main cam shaft 26 are not rotated or rotated at less than a defined speed, a rocker arm 50 which is energized clockwise by means of an extension coil spring is in a prescribed condition and a pressure reducing cam 42 is projected out of the reference face of an exhaust valve lifting cam 30. That is, since a centrifugal force which acts on the weight of a centrifugal type governor 48 which is rotated in an integrated form with the sprocket 24 is smaller than the tensile force of the spring, the pressure reducing cam 42 operates a rocker arm 35 at the time of compression stroke, to slightly lift up an exhaust valve. An a result, part of compressing pressure is allowed to escape reducing an inputted starting torque, thereby, improving a starting property.

Title: Light-emitting diode
Inventor: KAWAI MASATADA
IPC: H01L33/62
Filed: 1985-06-27
Abstract: PURPOSE:To improve the lowering of illuminance and the nonuniformity of illuminance distribution largely by making the area of an electrode on a wire- bonded chip the same as or smaller than the area of shielding of beams by a wire after deformation on wire bonding. CONSTITUTION:In a light-emitting diode in which an electrode for a light- emitting diode chip bonded onto one lead and the other lead are connected by a wire, the area of the electrode is made the same as or smaller than the area of shielding of beams by the wire on the electrode after deformation on wire bonding. Consequently, beam shielding by the electrode can be prevented. A beam shielding section is determined by the connecting section of the wire having an extremely small area, and the area of shielding of beams is reduced, thus enabling the increase of the amount of light to the front. Consequently, the beam shielding section is minimized, thus also inhibiting the generation of the nonuniformity of illuminance. Wire bonding to the electrode is conducted particularly by second bonding 5b, thus suppressing the increase of the amount of light and the nonuniformity of illuminance distribution more effectively.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of pad forming steps and improve reliability and yield through elimination of the positional deviation between pads and solder balls by forming pads directly on wiring, without going through through- holes for their connection with the wiring and thus connecting the pads directly to the wiring. SOLUTION: An uppermost wiring 16 on a semiconductor substrate 18 is formed of Cu, and not only a cover film 14 is formed on the wiring 18, but also an opening 13 serving as a pad 12 is formed. Successively, the opening 13 is filled with Cu, and an unwanted Cu portion on the film 14 is removed by chemical and mechanical polishing(CMP), and the pad 12 is formed in the opening 13 of the film 14. The pad 12 is formed directly on the wiring 16 without going through a through-hole for its connection with the wiring and is further connected directly to the wiring. As a result, the number of pad forming steps can be reduced, and the reliability and yield of pads can be improved, while eliminating the positional deviation between the pad and solder ball. Furthermore, the amount of each pad dished by CMP can be reduced also.
