Title: Target extracting device
Inventor: NAKAGAWA MASAHIRO
IPC: G06K9/46
Filed: 1986-01-09
Abstract: PURPOSE:To exactly perform the detection of a target by detecting a picture element string having a picture element string length longer than that of the target, generating a mask pattern signal, eliminating an object having an area larger than that of the target from the mask pattern signal, and performing a binarization on the signal from which the object having the area larger than the target is eliminated. CONSTITUTION:A picture element string measurement circuit 15 measures the length of the picture element string in which significant binary-coded video signals 7 are continued, and outputs a picture element string data signal 16, and also, the picture element data signal having the length longer than a regulated length out of the picture element string data signals 16 is stored on a picture element string data memory 17. It is assumed that the length of the picture element string 23 of an object 12 having the area larger than a target 11 is set as L, and the length of the picture element string 24 of the target 11 is set as (l). Assuming that a value that satisfies L>m>l is set as (m), the picture element string data memory 17 stores only the picture element string having the picture element string length more than (m). For example, when above stated binary-coded picture is inputted to a mask pattern generation circuit 18, a mask pattern signal 19 which masks only the picture element string 23 of the object 12 having the area larger than the target 11 is outputted from the mask pattern generation circuit 18.

Title: Semiconductor memory
Inventor: OKUYAMA HIROAKI
IPC: G11C11/41
Filed: 1989-01-10
Abstract: PURPOSE:To offset delay in an output circuit and delay in a word line and to minimize the difference in access time for respective plural data outputs by arranging memory cell arrays, which correspond to the data outputs and are arranged in a sequence from one array having data with the maximum delay in the output circuit, in another sequence from one array having the data with the minimum delay in the word line. CONSTITUTION:A word line WL is selected by a word line driving circuit 1, and since delay occurs in the word line WL because of its wiring resistance and wiring capacity, while a memory cell array M4 arranged closer to the circuit 1 is selected earlier, an array M1 arranged farther from the circuit 1 is selected later, and the data of respective cells are to be transmitted to output circuits O1-O4. Since resistances R1-R4 also exist in a reference potential wiring 2 from a reference potential terminal 3 to the circuits O1-O4 in the circuits O1-O4, delay occurs in the output data, and while the delay becomes larger for the circuit O4 having the larger resistance of the wiring 2, the delay becomes smaller for the circuit O1 having the smaller resistance. Thus, whole access time can be shortened by considering the arraying sequence of the arrays M1-M4.

Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide power amplifiers for amplifying an output from a photoelectric voltage transformer or the like with a high gain, and for outputting it to a load such as a protecting relay on double buses, and to prevent excess currents due to deflection between those power amplifiers or the malfunction of the load when they are connected with the load in switching the buses. SOLUTION: A difference between an input voltage VI and a step-down value VO of an output voltage is amplified by an error amplifier 45, and negative feedback control is operated in this power amplifier 31(31a). In this case, the output voltage of a DC power source 34 realized by a DC/DC converter or the like is detected by a voltage detecting circuit 53, and when this is higher than a rated value, that is, the inflow of currents is detected, a switch 54 provided at the output side of the error amplifier 45 is electrically conducted to a prescribed fixed potential side, and error amplification is stopped. Therefore, the transfer of a power generated due to deflection between those power amplifiers can be reduced in a prescribed level, and excess currents or the malfunction of a load 33 can be prevented.

Abstract: PURPOSE:To prevent gain reduction at a high frequency region by connecting respectively a positive feedback resistor and a negative feedback resistor from the drain of the 2nd and 3rd stage of FETs of three-stage connection to the gate of the 1st stage via a coupling capacitor. CONSTITUTION:A positive feedback path from the gate of the 2nd stage to that of the 1st stage is not provided in a conventional three-stage negative feedback amplifier circuit and the gain reduction at a high frequency region of >=1GHz is remarkable, and in connecting a resistor R8 and a capacitor C5 between the drain of an FETQ2 and a gate of the 1st FETQ1 to form a positive feedback path, then gain keeping is attained at a region of 1-2GHz. Thus, the region whose gain is decreased by 3dB conventionally is extended from 1.2GHz to 2.2GHz and high gain at a high frequency region is attained.

Title: Television camera
Inventor: SEKIGUCHI TAKESHI
IPC: H04N9/097
Filed: 1978-01-17
Abstract: PURPOSE: To prevent the shading of the bias light and thus to obtain a high-quality TV picture by forming four units of the prism forming the color separation prism system with the glass of high refractive index of 1.6 or more.  
     CONSTITUTION: Vertical angles θ 1 ∼θ 4  of four units of the prism are set to satisfy the conditions shown in Eq. [I]. The constitution of the color separation prism system features prism 12 of the vertical angle 13 or less sticked to the back of 1st prism 11 with the dichroic film applied to prism 11 or 12. The image-forming luminous flux emitted from lens 4 enters prism 11 through incident face 11' of the color separation prism system, and only the beam of the blue color region is reflected at dichroic face 11" with other wavelength regions being transmitted. Here,  prism 11 and 12 are pasted together via the adhesive featuring nearly same refractive index as the glass, so the full reflection is avoided at face 11" except for the  beam of the wavelength region which is reflected forcedly by the dichroic film.  Thus, an optical system featuring a small F number can be obtained.
