Title: Diversity reception station
Inventor: OTSUKA SHIGERU
IPC: H04B7/08
Filed: 1988-06-10
Abstract: PURPOSE:To attain the diversity reception independently of a signal form of a time slot signal by adopting the constitution such that delay devices are arranged in series at the post-stage of a demodulator and a demodulation data is inputted to a diversity changeover device after the changeover device is switched. CONSTITUTION:The reception signal outputs of a 1st receiver 12 and a 2nd receiver 22 are subject to demodulation processing respectively at a 1st and 2nd demodulators 13, 23. Each reception data subject to demodulation processing is inputted to a changeover device 101 via a 1st and 2nd delay devices 14, 24. The changeover device 101 selects either larger output from the said delay devices 14, 24 based on a switching signal from a comparator 102. Since the 1st and 2nd delay devices apply delay processing as to the inputted reception data so that the head is outputted after the point of time when the said switching signal is generated, no pulse distortion takes place in the selected reception data.

Abstract: PURPOSE:To obtain a solid stage image pickup element which can improve dynamic range, reduce a dark current, improve a blooming suppression rate and reduce the size of pixels by increasing the signal storage capacity of a vertical CCD shift register which gives the upper limit in the storage charge amount. CONSTITUTION:A low density diffused layer 7 for buried channel is of reverse conductive type (e.g., P type) to a semiconductor substrate 6 of the first conductive type (e.g., N type), and increased in the density of impurity as compared with the substrate 6. CCD electrodes 8, 9 are formed of polycrystalline silicon of the first layer and the polycrystalline silicon of the second layer which is slightly superposed with the first layer. An impurity layer of the first conductive type is formed on the surface 11 of the semiconductor under the polycrystalline silicon electrode 9 of the second layer so as to provide a difference from the surface potential formed under the first layer electrode. The diffusion depth Xch1 of a channel 7-1 forming a vertical CCD shift register is set shallower than the diffusion depth Xch2 of channel 7-2 forming a horizontal shift register. In this manner, the capacity of the CCD electrode and the maximum storage charge amount can be increased by twice as compared with the conventional element, thereby increasing the dynamic range.
