Title: Superconductive direct current driving logical circuit
Inventor: KODERA NOBUO
IPC: H03K19/195
Filed: 1980-06-06
Abstract: PURPOSE:To obtain a general-purpose logical gate for integrated circuit use that can be driven with a DC power source, by forming a logical circuit which can obtain the arithmetic output of both an OR logic and an NOR logic at one time. CONSTITUTION:The upper side of a basic circuit is connected to a DC power supply line P1 via a series resistance R3; and the lower side of the basic circuit is  earthed via a resistance RD. At the same time, a bias input loop is provided to generate an interlinking magnetic flux simultaneously with junction switches g11 and g22. Then two magnetic field coupled input lines are disposed so as to generate an interlinking magnetic flux simultaneously with switches g11 and g12 as well as g21 and g22. Then a combination is formed so that the input magnetic flux to g11 and g22 becomes opposite to the code of the bias magnetic field. Thus an OR output is extracted from the middle point between g11 and g12, and at the same time an NOR output is extracted from the middle point between g21 and g22, respectively.

Title: Video signal processor
Inventor: JIYON HOOMA FUARII
IPC: H04N5/14
Filed: 1989-03-27
Abstract: PURPOSE: To prevent any blooming phenomena by providing a means for separating a capacitor and a capacitance from an impedance in the output circuit of display driving amplifier for the positive and negative amplitude excursion of a video output signal. CONSTITUTION: A video signal obtained from the low impedance output of an amplifier 20 is transmitted through a signal connecting path including first and second serially connected resistance 52 and 28 for limiting the video signal driving of a video tube when a video driving signal with a large amplitude arrives to a picture display. A capacitor 54 is connected between the both ends of the first resistance 52 for high frequency compensation so that the high frequency information part of a displayed picture can be improved. The capacitance of this capacitor 54 is separated from the output circuit of a display driving amplifier 20 against the positive and negative amplitude excursion of the video signal in the same way as the capacitance of the video tube.  Thus, the signal driving for the video tube can be limited in response to the video signal with a large amplitude, and the blooming phenomena can be prevented from being generated.

Title: Method and apparatus for inspecting pattern
Inventor: WADA KOICHI
IPC: G03F1/84
Filed: 1995-03-31
Abstract: PURPOSE: To drastically decrease pseudo defects and to greatly improve throughput by storing periodic patterns as reference patterns, then scanning the regions where these periodic patterns exist and comparing these patterns with the reference patterns at the same period each. CONSTITUTION: A cell region 201 is composed of repeating patterns for both memory IC and logic IC. For example, the pattern of the region 201 is composed of the repeating patterns with a pattern 205 as one period. The pattern 205 of one period to be formed as the reference is inputted in the form of an image and is stored by binarization. Next, the pattern is moved to a start pattern 206 to be inspected and this pattern is inputted in the form of the image and is compared with the initially stored reference pattern 205. The difference therebetween is observed. The images are recognized in such a manner that the ends of the adjacent patterns for one period overlap on each other by several 10μm each to avert the overlook by an error in the position accuracy in the case the patterns for >=2 periods are stored as the reference patterns.  The comparison of the actual mask patterns with each other is executable and since the area to be taken in one time is widened, the pseudo defects are drastically decreased and the detection accuracy is improved.

Title: Semiconductor device
Inventor: SHIMOJI NORIYUKI
IPC: H01L27/115
Filed: 1993-04-02
Abstract: PURPOSE:To provide a semiconductor device, ensuring reliable writing even in the case of large-scale integration. CONSTITUTION:When a non-volatile memory is formed, a control gate 4 is formed via a selective layer 3 on a field oxide film 25. Thus, high voltage applied to the control gate 4 does not influence the element formation region 25 by controlling a selective layer 2 when information is written. Thus, a channel is not formed under the field oxide film 15 due to the influence of the high atmospheric pressure. There is no fear of channel formation and it is not necessary to form the field oxide film 25 (element isolation region) for preventing a channel from being formed, allowing integration. Moreover, there is no channel formed so that the element is reliably isolated, allowing reliable writing.

Title: Filter coefficient arithmetic unit
Inventor: MATSUMOTO MASAHARU
IPC: H03H15/00
Filed: 1987-03-30
Abstract: PURPOSE:To shorten a computing time, by dividing a desired amplitude frequency characteristic into plural band areas, and performing Hilbert transformation by expressing the amplitude frequency characteristic of each band area discretely. CONSTITUTION:A band division circuit 2 divides an inputted amplitude frequency characteristic into the plural band areas, and also, thins out the points of the amplitude frequency characteristic to express the characteristics of divided band areas with a fewer points. Following that, a transfer function is found from each of the band areas by using the relation of the Hilbert transformation at an arithmetic circuit 3, and an FIR(transversal filter) coefficient is found by applying reverse Fourier transformation at a reverse Fourier transformation circuit 4. Furthermore, the delay time of the FIR coefficient of each band area is corrected at a delay circuit 6 via a sampling point interpolation circuit 5, and the FIR coefficient to realize the desired amplitude frequency characteristic is found by passing them through a low-pass filter 701, a band-pass filter 702, and a high-pass filter 703 and synthesizing them at an adder circuit 8, Thus, since no excessive amount of data are required to express the characteristic of each band area, the computing time can be shortened.
