Title: Solid-state image pickup device
Inventor: HARADA NOZOMI
IPC: H04N5/335
Filed: 1986-09-05
Abstract: PURPOSE:To prevent the deterioration in color reproducibility or to prevent signals of dark parts from not appearing by arranging an N-type drain layer arranged on a P-type Si substrate and an overflow control electrode for controlling a surface potential of the substrate between said drain layer and an N-type layer. CONSTITUTION:A drain N<++> layer 13 which is adjacent to an N<+> layer 5 and is used as an overflow drain and an overflow control electrode 14 for controlling a surface potential of a substrate 1 between said layers 13 and 5 are arranged. During a storage duration subsequent to a signal read-out duration, a transparent electrode 7 is kept at higher level than the surface potential of the layer 5 for an arbitrary duration. Then, it is kept at lower level voltage for storing the next signal charge. In the initial period of that, the potential of the electrode 14 is changed into that of high level and the potential of the layer 3 is changed into that of low level, thereby implanting the charges into the layer 5 from the layer 13 so as to determine a surface potential of the layer 5. Thus, a voltage which leaves the signal charges in the layer 5 is applied and nextly an insufficient quantity of charges is implanted from the layer 13, thereby preventing the phenomenon that the signals of dark parts of an object do not appear as outputs.

Title: Image forming device
Inventor: SUMIDA SACHIKO
IPC: G09G5/36
Filed: 1990-08-06
Abstract: PURPOSE:To make the bit map development of an image at high speed by dividing a polygon shown by vector information by a scan line passing the vertexes into the minimum number of triangles and a quadrangle whose two sides are parallel to these. CONSTITUTION:The polygon given by the vector information is divided into the minimum number of triangles and a trapezoid whose two sides are parallel to the scan line by a straight line parallel to the scan line passing the vertexes. Each side is made approximate to an integral coordinate. However, when the side is parallel to the scan line, the approximation to the side is not executed. And, an edge list is prepared and registered on a RAM. Then, it is judged whether the coordinate registered on the edge list is the starting point to paint- out, or not, and in case of the starting point, the paint-out to the next coordinate is executed. The process is finished when the paint-out is completed. Thus, a process speed is improved without a decimal arithmetic or a half-adjust.

Title: Received electric field monitor device
Inventor: SEKI YOSHIKAZU
IPC: H04W88/02
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To prevent an electric field monitor and reception part from being damaged by preventing an excessive high frequency signal from being inputted to an electric field monitor part. SOLUTION: This reception electric field monitor device limits a high frequency signal received by an antenna 1 to the band of a radio channel of a mobile communication system applied to a reception band filter part 2 and then amplifies it by a receiving amplification part 3. A detection part 4 passes the received high frequency signal to a variable attenuation part 5 and detects the level of this high frequency signal, thereby outputting a detection voltage (d). The variable attenuation part 5 attenuates the high frequency signal to the level corresponding to the control signal from an attenuation quantity control part 7 and sends it to the electric field monitor and reception part 6.  The electric field monitor and reception part 6 generates an RSSI voltage (r) of level corresponding to an operating frequency signal included in the high frequency signal having passed through the variable attenuation part 5 for practical and lowers the RSSI voltage (r) to the 0 level at a halt. The attenuation quantity control part 7 normally responds to the RSSI voltage (r), but generates a control signal (s) responding to the detection voltage (d) when the RSSI voltage (r) is at the 0 level.

Filed: 1985-09-18
Abstract: PURPOSE:To obtain a converter having low-noise characteristic by providing a special surge protecting circuit in parallel with the input of an amplifier and coupling an antenna element consisting of a helical antenna or a strip line antenna and the low-noise amplifier directly by a line. CONSTITUTION:A surge protecting circuit 8 is inserted in parallel to an input line 3' of a low-noise amplifier, and a helical antenna part 1 and a low-noise amplifying element 4 are coupled directly. The surge protecting circuit 8 consists of a stub which has one end grounded through a through hole 10 and has the other end connected to the input line 3'. A length (l) of the stub 9 is a quarter wavelength of a signal frequency fs. Consequently, the stub 9 is equivalent to an open line for the signal frequency fx at the connection point between the input line 3' and the stub 9, and the stub 9 has no influences upon an input matching circuit 3 at all. Even if a surge voltage of thunderbolt or the like is generated in an antenna part 1, the surge current is by-passed through the stub 9 and the earthing through hole 10 to prevent the amplifying element 4 from being broken down by the surge.

Abstract: PURPOSE:To eliminate a large difference in retrieval time among data by transferring data which are read out at specific address intervals to a main storage device on the basis of the record length, the number of records, and the size of a main storage area of data transferred from an external storage device. CONSTITUTION:The data from the external storage device 1 is transferred to the main storage device 4 through a buffer 2 and a registering circuit 3. The record length, the number of records, and the size of the main storage area are set in a registration decision circuit 5 by program execution.

Title: Exposure device
Inventor: TOGUCHI MANABU
IPC: G03F7/20
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To expose without deteriorating accuracy, and to shorten the exposure processing time by applying enlargement ratio being decided corresponding to a forming accuracy of the pattern of a mask and the line width projected on a photosensitive plate, with respect to a projection optical system. SOLUTION: As for this device when assuming for instance, the desired line width exposed on the plate 10 as 1μm, and the enlarging ratio as 1.5 times, the line width on reticle R becomes 1/the ratio of enlarging projection optical system (reciprocal number of projection enlargement ratio), that becomes to 0.666..., which is not divisible. Accordingly, when assuming the ratio as 1.25 which is the ratio between 1.0 to 2.0, magnification in the first lace, the calculated reciprocal number of the enlarging projection becomes to 1/1.25=0.8, hence the line width 0.8μm of a pattern on the reticle R is made possible of plotting a desired pattern in a satisfactory high accuracy, in the case of adopting the electrostatic beam plotting device whose minimum plotting unit of the electron beam is 0.05μm in a practical level.  In such a manner, the enlargement ratio is decided corresponding to the forming accuracy of the pattern of the mask and the projecting line width.
