Title: Antenna selective diversity receiver
Inventor: MURAI HIDESHI
IPC: H04B7/08
Filed: 1990-01-31
Abstract: PURPOSE:To obtain a reception characteristic with high quality by comparing a reference level and a level median at both branches, selecting a prescribed selection criterion from plural antenna selection reference values and selecting a succeeding TDMA burst based on the selected selection criterion. CONSTITUTION:An obtained level median is compared with a predetermined reference level at a comparator 55 and an antenna selective discriminator 52 revises the selection criterion from level comparison of a just preceding burst into a selection reference signal. That is, when a level measuring value at the end of a time division multiple address(TDMA) burst of its own channel is a value required to satisfy a prescribed error rate and its own succeeding channel TDMA burst is received by a current antenna 1a or 1b. When the value is a required value or below, an antenna selection signal is outputted so as to receive a succeeding own channel TDMA burst with a different antenna 1b or 1a from the current antenna. Thus, the reception characteristic with high quality is obtained.

Title: Electrophotographic method
Inventor: MIYAGI KOUJI
IPC: G03G15/047
Filed: 1984-02-09
Abstract: PURPOSE:To prevent a ghost image due to preceding hysteresis by executing destaticizing exposure with light including a component longer in wavelength than the light used in imagewise exposure and setting one of binary densities to the sufficiently saturated region on a development characteristic curve. CONSTITUTION:Destaticization exposure is carried out with light including a component longer in wavelength and easier to diffuse into the inside of a photosensitive body than the light used for exposure, and one of binary densities on a development characteristic curve to the inside of a sufficiently saturated region. A light short in wavelength is strongly absorbed in the shallow part to enlarge an electrostatic positive space charge region in a p type photosensitive body, a light longer in wavelength intrudes deeply to increase a negative charge. Accordingly, when said density is set to the latter condition, since a negative ghost image corresponds to the saturated region of the characteristic curve, it does not affect developing density. The same result is obtained in the case of an n type photosensitive body. As a result, gradation can be reproduced with a density having no problem in the area gradation method by setting one of binary densities to the sufficiently saturated region on the development characteritics curve.
