Title: Image detection system
Inventor: YUGAWA KAZUHIKO
IPC: H04N5/232
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To provide signal charges with sufficient contrast and to realize accurate automatic focusing by switching addition/non-addition in a vertical direction and a horizontal direction on the signal charges obtained in area sensors. SOLUTION: The charges of the plural pixels are added during the transfer of the charges. Thus, a range to be read becomes large but the number of the pixels to be read does not change. When the preceding detection result is not reliable (#40), whether the preceding integration is under low luminance or not is judged (#45). When the integration is under low luminance, the reading of this time is executed in addition mode (#55). When preceding integration is not under low luminance and this reading mode is an addition mode, the reading this time is executed in the non-addition mode (#60) and the reading this time is executed in the addition mode when the preceding reading mode is the non-addition mode. Thus, data by this integration is read at the optimum read mode based on the preceding detection result and brightness.

Title: Magnetic head device for floppy disk device
Inventor: YAMAGUCHI MASAHITO
IPC: G11B5/265
Filed: 1987-10-31
Abstract: PURPOSE:To prevent an adverse influence on the side of a read/write gap due to an increase in an erase current by providing a high saturation magnetization member on a confronting surface on the side of the read/write gap among the confronting surfaces where an erase gap is composed of an erase core. CONSTITUTION:When low density recording is executed with respect to a recording medium, it is necessary to increase a write current and to enlarge a recording magnetic field, and it is also necessary to increase the erase current and to enlarge an erase magnetic field. In such a case, a comparatively large magnetic flux G occurs in the erase core 10, and a large leakage flux occurs in the erase gap 14. Since the high saturation magnetization member 15 is provided near the erase gap 14 of the erase core 10, the leakage flux from the erase gap 14 is in a state that it is easy to flow to the side of the high saturation magnetization member 15. Thus, the increase in the asymmetrical components of a signal waveform and the like can be controlled by the large erase leakage flux at the time of recording signals by the read/write gap 13.
