Title: Communication system
Inventor: KAWAMURA HIROSHI
IPC: H01Q23/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To design optimum antenna gain and radiation pattern corresponding to the using form of a device by mounting individual demodulation circuits to respective antennas and combining signals after demodulation. SOLUTION: Data 101 are modulated in a modulator 102 and radiated by the antenna 103 for transmission. Radiated electromagnetic waves are received by plural element patch antennas 104-106 and demodulated in demodulators 107-109 installed in the respective element patch antennas 104-106 and the signals are combined in a combiner 110 and outputted as the data 111. A modulation system in this case is amplitude modulation, and by turning it to the amplitude modulation, the demodulator 102 can be constituted of only a diode for detection and a low-pass filter. Thus, at the time of receiving radio waves in the respective element patch antennas 104-106, since they are demodulated immediately after the signals are outputted from the respective element patch antennas, an output signal frequency after the demodulation becomes the same as a modulation signal frequency. Thus, the signals are combined in a common mode at all times.

IPC: G03B27/72
Filed: 1982-12-24
Abstract: PURPOSE:To obtain a correct copy by comparing the output signal of the large area of an original with that of its small area after correction of the areas, and controlling the image density in accordance with that higher output signal. CONSTITUTION:A photodetector 22A for detecting a state of the large area of an original, and plural photodetectors 22B for detecting states of its small areas are arranged, and the output (a) of the detector 22A is compared with those (b) of the detectors 22B after correction of the areas. The comparison of both outputs is executed by calculating a'/b or b'/a, where a'=aXSB/SA, b'=bXSA/SB, SA, SB are the area of the original of light incident to the photodetector 22A, and those of the lights incident to those 22B, respectively. When the detector 22B detects lines or a fold, misjudging it as the background of the original can be prevented by detecting its larger area and complementing it. On the other hand, if only the larger area is detected, since the reflected light amt. depends upon the amt. of printed characters, the smaller areas are detected and when the output of the smaller area is lower than that of the larger area, it is judges as misdetection, and priority is given to the output signal of the detector 22a.

Title: Semiconductor laser
Inventor: SHIMADA KATSUTO
IPC: H01S5/00
Filed: 1987-09-18
Abstract: PURPOSE:To produce a semiconductor laser in which an exterior derivative quantum efficiency is high and driving current is small when output is large, by forming a first clad layer in a stripe shape which is wider on the side of a buffer layer while narrower on the side of an active layer, and by forming a second clad layer in a stripe shape which is wider on the side of the active layer while narrower on the side of a contact layer. CONSTITUTION:In both a first and second clad layers 103, 105, their upper stripe widths are narrow compared with the lower stripe widths thereof. A ZnSe layer 107 has a large resistivity of 10 MOMEGA or above so that when current is caused to flow between a GaAs substrate 101 and a GaAs contact layer 106, the bulk of the current flow is present only in the stripe section. Therefore, the reactive current, which does not contribute to laser oscillation, is small, and the threshold current is also small. Moreover, because the refractive index of the ZnSe layer 107 is smaller than that of each of the first and second clad layers 103, 105, and the active layer 104, most of the lights generated in the active layer 104 are effectively confined within both the active layer 104 and the stripe section of the first and second clad layers 103, 105.

Filed: 1989-09-07
Abstract: PURPOSE:To obtain excellent precision in machining and an arbitrary detecting characteristic by detecting a magnetic flux generated by an exciting means in a gap formed between a fixed magnetic substance and a magnetic substance coupled rotatably thereto. CONSTITUTION:When an exciting current is made to flow through an exciting coil 1, a magnetic flux piercing through magnetic cores 2 and 3 is generated. Since a detecting coil 4 is provided in a gap between magnetic poles of the magnetic core 2 and the magnetic core 3, an electromotive force being proportional to an interlinking magnetic flux is generated in the coil 4. The coil 4 is composed of coils having identical shapes 4a to 4d symmetrically. When the magnetic core 2 is located at a position as shown in the figure, the amounts of magnetic fluxes interlinking to the four coils are equal, and when the magnetic core 2 is rotated clockwise, for instance, the magnetic fluxes interlinking to the coils 4a and 4b increase, while the magnetic fluxes interlinking the coils 4c and 4d decrease. By checking the amplitudes and phases of output signals from two output terminals 4, accordingly, the direction and angle of rotation to the magnetic cores 2 and 3 can be known. It is easy to machine a prescribed excellent gap with excellent precision.
