Title: High frequency power amplifier
Inventor: TAROUMARU MAKOTO
IPC: H04B17/10
Filed: 1991-05-30
Abstract: PURPOSE:To detect power passed through an output transmission line without using any directional coupler even when the standing wave ratio of the same transmission line is high. CONSTITUTION:A 90 deg. phase shifter 7 is connected to the output of a power amplifier circuit 1, a transmission output is obtained from the output of the phase shifter 7, a first detector 5a detects a high frequency voltage at the input terminal of the phase shifter 7, a second detector 5b detects a high frequency voltage at the output terminal of the phase shifter 7, the output voltage of the second detector 5b is added to the output voltage of the first detector 5b by an adder 8, and the output voltage of the adder 8 is defined as a passed power reference voltage. Thus, even when the standing wave ratio of an antenna is high, the passed power can be detected. Further, by calculating the square sum of the said high frequency voltages, detection error can be reduced.

Title: Image processor
Inventor: TOMOSADA MASAHIRO
IPC: G03G21/00
Filed: 1984-06-21
Abstract: PURPOSE:To obtain a copy image with proper contrast even from an original with low contrast by setting its copy density on the basis of the difference from the maximum value of original density detected by a reflection density detecting means. CONSTITUTION:When the reflection density of an image area is detected by the photodetecting element group of the relfection density detector 35 for each picture elememt, picture elements with a low reflection factor are obtained after a set of picture elements with a high reflection factor. For example, when the picture element having the maximum reflection factor in the set of picture element having a low reflection factor has a density of 0.07 and the picture element with the minimum reflection factor has a density of 0.5, an input voltage of 65V is applied to an irradiation lamp 25 to determine the potential of a drum according to an E-V characteristic, thereby obtaining a copy image with density determined by the development characteristic. In this case, its original density is equal to the copy density. When the difference between the maximum and minimum of the original density is smaller than a predetermined value, on the other hand, the input voltage to the irradiation lamp 25 is controlled to give artificial contrast to an original 20 with low contrast, and the proper density is set, thereby obtaining a sharp copy image.

Title: Peak display device for preventing overload in arithmetic unit for digital signal
Inventor: TANAKA YOSHIAKI
IPC: G06F17/10
Filed: 1987-05-25
Abstract: PURPOSE:To prevent the result of digital arithmetic operation in a device from overflowing actually in an excellent way by applying overflow display even when the result of operation is large enough to prevent a predetermined margin. CONSTITUTION:A digital signal processor DSP multiplies a coefficient ax with the result of substantial arithmetic operation to cause a detection output in the overflow state when the substantial arithmetic result is large enough to exceed the margin for overflow prevention determined in advance. A pulse outputted to an output terminal 10 of a drive circuit DRC of a display section is fed to a display section DPA and the display of overflow or overload is applied. Since the margin for preventing overload is selected optionally by the coefficient ax, the overflow prevention with high accuracy is realized by selecting the margin to an optimum value in response to the property of the input signal.
