IPC: H01L27/092
Filed: 1986-02-07
Abstract: PURPOSE:To prevent the doping of impurities as well as to contrive to suppress the increase in contact resistance between a wiring layer and an Al wiring layer by a method wherein, when an impurity doping is performed for the purpose of forming a source and drain region, the junction part of the wiring layer linking to a gate electrode and an Al wiring layer and a part of the wiring layer linking to said junction part are masked. CONSTITUTION:The Al wiring layer 9 connected to the source and drain regions 6 and 7 of N and P-MISFET (metal insulating semiconductor field effect transistor) QN and QP respectively is formed on the interlayer insulating film 8 consisting of phosphosilicate glass, and it is also connected to a gate electrode 5 through the intermediary of a contact hole. The N<+> type source and drain region of the N-MISFET is formed by performing ion implantation using arsenic (or hosphorus) as impurities. At this time, masks M1 and M2 are formed in order to prevent impurities from introduced into the P-MISFET QP forming region and a part of a poliycrystalline silicon layer 5. Then, the p<+> type source and drain region 7 of the P-MISFET is formed by performing ion implantation using boron as impurities. Masks M3 and M4 are formed for the purpose of preventing introduction of impurities into a part of the N-MISFET QN forming region and polycrystalline silicon layer 5.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To stably produce a polyester having reduced cloudiness and good hue by polycondensing terephthalic acid and ethylene glycol as main components in the presence of a polycondensation catalyst comprising antimony trioxide having specified or smaller lead and arsenic contents. SOLUTION: Antimony trioxide having a total content of lead and arsenic of 100 ppm or below is used.

Title: Fuse
Inventor: AIKAWA TAKEHIRO
IPC: H01H85/02
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To prolong the breaking life time of elements resulting from the normal on/off of a current by providing corrugated irregularities, increasing the heat radiating area of an insulator on the outer periphery, or providing heat transfer projections on the inner face, or arranging the elements into a square shape, and providing projections parallel with the elements on the inner face between the elements. SOLUTION: A tubular insulator 1a formed with irregularities 1p on the outer periphery is used. The irregularities 1p may be formed on the outer periphery of an angular insulator 1a, or they may be formed in the vertical direction. The heat radiating area of the outer periphery of the insulator 1a is thereby increased, the heat radiating effect by excitation is increased, and the temperature rise of elements can be suppressed low. When an insulator 1a formed with projections on the inner face is used, the elements are arranged into a square shape between the projections on the inner face. The radiated heat of multiple elements is uniform and easily reaches the outer periphery of the insulator 1a, and heat radiation can be accelerated. Heat radiation efficiency is improved, the temperature rise in the elements is kept low, and the life time can be prolonged.

Title: Copy restriction medium
Inventor: JIYON GASUPAA
IPC: B42D15/10
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain copy restricting means which needs no digital technology by laminating at least one image forming layer on a support layer via a microdot pattern, and forming a copy restricting medium to thereby form an original copy restricted without lowering the quality of the original. SOLUTION: To give the copyright restriction to a hard copy information- containing original, the pattern of microdots 15 is assembled with the part of the image 12 of a original 10. It is enlarged and displayed in a window 14 so as to observe the pattern, but normally when the image 12 is observed, the pattern cannot be easily confirmed. Since the microdot pattern assembled with the original is not observed by eyes in the normal original handling state, the beauty of the original is not lost, and the original can be used with high quality. Since the microdots are assembled in the entire surface of the original, the certainty of the detection is increased, and simultaneously it cannot be removed from the original.

Title: Information storing method and information reproducing method
Inventor: SAEKI MASAHARU
IPC: G11B20/12
Filed: 1995-02-14
Abstract: PURPOSE: To differentiate only a language audio signal on the same video image instantaneously by storing plural kinds of information sets comprising video image and audio signal, only audio signal and only video image in a form of files to an information storage device while the video image and the audio signal are synchronously with each other. CONSTITUTION: Plural sets of information comprising video image and audio signal, only audio, signal and only video image in a form of files 12, 13, 15 to 17 are stored in an information storage device (CD-ROM) 8 while the video image and the audio signal are synchronously with each other. When the video image and the audio signal, synchronously with each other are stored in the CD-ROM 8, since the files are synchronously with each other even in the case of reproduction, even when a language is selected from English into another language, the audio or character (super) signal is reproduced completely synchronously with the video image and switched instantaneously to make a synchronization error (asynchronous state) zero.  Thus, the deviation due to asynchronization of the video image and the audio signal at switching is completely avoided and this method is effective when the conversation and the audio signal of the video signal and the reproduction of the video image are used for education or the like.

Title: Low iron loss grain oriented silicon steel plate with characteristic not deteriorated due to stress relieve annealing
Inventor: KOMATSUBARA MICHIRO
IPC: H01F1/18
Filed: 1988-02-08
Abstract: PURPOSE:To prevent characteristics from being deteriorated due to stress relieve annealing, by making a foreign matter, whose composition is different from that of a base iron part, locally exist on a base iron surface layer part of a grain oriented silicon steel plate which is coated with a forsterite film. CONSTITUTION:A foreign matter, whose composition is different from that of a base iron part, is made to exist on a base iron surface layer part of a directive silicon steel plate which is coated with a forsterite film and has no plastic strain region on the base surface layer part. Further, the forsterite film is coated with an insulating film which is of tension application type and is 9.8X10<-6>1/ deg.C or less in its coefficient of thermal expansion. Now that surface tension is applied depending on a difference between the coefficient of thermal expansion of the steel plate and that of the coating film, there must be a degree of the difference between said coefficients in order to determine a species of coating processes. In this respect, however, if the coefficient of thermal expansion is 9.8X10<-6>1/ deg.C or less in the coating, a satisfactory valve of low iron loss can be obtained from an synergistic effect which consists of an effect of forming a region, where the foreign matter exists on the base iron surface layer part, and an effect of surface tension application by the coating film.
