Patent JP-H10284700-A (JP)
Title: Manufacture of semiconductor integrated circuit device and semiconductor integrated circuit device
Inventor: WATABE KOZO
IPC: H01L27/108
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To ensure a sufficient contact area at the bottom of a contact hole, even if the contact hole is shifted a little in the direction crossing a wiring by a method, wherein the connection hole is drilled in a self-alignment manner and its shape is so formed as to be long in a direction crossing the wirings adjacent to each other. SOLUTION: The shape of a connection hole STC for a capacitor is such that a dimension in the extension direction of a bit line BL is larger than a dimension in the widthwise direction of the bit line BL. Therefore, the area of the upper surface of a plug P, which is exposed from the opening of the connection hole STC 51 for the capacitor, i.e., the contact area between the storage electrode of the capacitor C and the plug P, is larger than the contact area in the case of a connection hole 51. Further, even if the position of the connection hole STC for the capacitor is shifted from the position of the pattern of the plug P, the contact area between the storage electrode of the capacitor C and the plug P can be fully ensured. Therefore, the electrical connection between the capacitor C and a selective MOS-FET Q can be improved.

Title: Ultraviolet-curable resin composition
Inventor: KUBO MOTONOBU
IPC: C08F20/00
Filed: 1984-05-08
Abstract: PURPOSE:The titled composition to which is imparted excellent curability by improving curing inhibition by oxygen, containing a specified allyl ether group- containing compound as a reactive diluent. CONSTITUTION:An ultraviolet-curable resin composition, prepared by adding a compound of the formula as a reactive diluent in place of or inconjunction with a conventional reactive diluent to a prepolymer having an ethylenically unsaturated bond. When a conventional reactive diluent is added to the prepolymer, the resulting composition can not form a cured product having a smooth surface by irradiation with ultraviolet rays in the presence of oxygen, because the inhibitory action of oxygen upon radical polymerization causes the surface in contact with oxygen (air) to remain sticky. Although there are a process in which the curing is performed in an inert gas atmosphere and a process in which an amine is used, these processes have a drawback that a special apparatus must be used, or the addition of an amine sometimes causes loss of the weather resistance of a cured film. By using the compound of the formula, it is possible to obtain an ultraviolet curable resin composition freed from the above drawback and having excellent curability.

Inventor: ISHIKAWA YOSHITOSHI
IPC: H02P9/14
Filed: 1978-07-28
Abstract: PURPOSE: To surely prevent the production of overvoltage in a trouble with an inexpensive means by controlling the field current according to an output voltage of the AC generator.  
     CONSTITUTION: The voltage-current characteristic and non-load saturation characteristic of the main AC generator 1 of the diesel electric locomotive are shown by a curve P or Q and the planing value is done by a curve R. When the characteristic is shown by the curve P, the voltage is higer than the planing value. In this case, when the second field winding 9 is connected in reverse polarity with respect to the first field winding 7 and the variable resistance 10 is adjusted, the charactiristic of generator can be agreed with the planing value. Thus an overvoltate is not produced in the generator when the load is opened, the diode of the rectifier 3 is protected. When the characteristic is shown by the curve Q, the field winding 9 can be connected in the same polarity with respect to the winding 7 and the resistance can be adjusted. By this way, the production of overvoltage can surely be prevented in a trouble.

Title: Method and device for preventing dubbing
IPC: H04N5/91
Filed: 1992-03-17
Abstract: PURPOSE:To effectively prevent illegal dubbing without affecting a video signal to be displayed. CONSTITUTION:A dubbing prevention signal adding device 3 applies a chroma signal C having an excessive amplitude, for example, 150% amplitude to a position corresponding to the over scan area placed around the part where the video signal is effectively displayed. Since this dubbing prevention signal having the excessive amplitude is placed in the part for insertion of the video signal and is not in the retrace period, it is not eliminated even in the color difference line sequence system and is taken as the object of automatic gain adjustment. The effective video signal is reproduced as a dark picture because a video signal recording and reproducing device 7 performs automatic gain adjustment of the following video signal, based on this excessive amplitude at the time of recording. Reproducing of this video signal means nothing.

Title: Semiconductor integrated circuit
Inventor: MATSUMOTO YURIE
IPC: G11C17/18
Filed: 1988-04-14
Abstract: PURPOSE:To certainly transmit an output state to the flip flop of the next stage so as to prevent a malfunction by reducing the OFF-leak current of transistors constituting a memory section. CONSTITUTION:In order to make an electric current hard to flow, a threshold voltage is changed. When, for example, the threshold voltages of n-channel MISFETs 1-1 to 1-n,..., 4-1 to 4-n are raised, the voltage inputted to a gate does not change, but tends to get OFF by the raised quantity of the threshold voltage and, as a result, the OFF-leak current becomes smaller. On the other hand, in order to make the electric current hardly flow, the size of the transistors are changed. Namely, the transistors are made narrower as much as possible in the width direction and longer in the length direction. Then the electric current is made smaller since the absolute quantity of carried electric charges decreases and the electric charges accumulated in a capacity can be kept certainly since the electric charges lose paths. Therefore, the content of this memory can be transmitted certainly to the next-stage flip flop and a malfunction can be prevented.

Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To enable easy registering of a printing position across the reciprocating scan stretch of a printing head and a printing position between plural printing heads at a printing device, without the necessity to depend upon the manual labor of a user or the like. SOLUTION: In a reciprocating scan by the printing head or a mutually supplemental printing process by a plurality of printing heads, a first and a second pattern including reference dots (e.g. dots formed by a forward scan or one of the printing heads) and dots formed in the different directions of a deviation between relative printing positions, are printed in coordination with plural deviation levels. Variations of the density of the first and the second pattern show identical characteristics and the characteristics of the density variations are only reversed by the directional property of a deviation direction. An intersection point for the characteristics of the two density variations is sought as an adjustment position where dot formation positions coincide with each other by utilizing the characteristics.

IPC: C09K3/14
Filed: 1982-06-01
Abstract: PURPOSE:To obtain a thin, strong and uniform covering by making an abrasive which includes graphite fluoride covered with a polymer, where the surface is graft-bound with vinyl resin. CONSTITUTION:Graphite fluoride covered with a vinyl polymer (graphite fluoride in the form of micro-capsules) is at least mixed with abrasive grain and binder and is molded by hot press to obtain an abrasive, in which additives are used often.
