Title: Target presentation device
Inventor: UENO TOKIO
IPC: A61B3/02
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To minimize the degradation of a target chart chart while presenting a target with sufficient light quantity and to prevent the generation of ghost images as well by arranging a reflection curved surface at a position where the eye to be tested faces a virtual image from an inspection window without interposing a beam splitter. SOLUTION: The eye E1 to be tested observes the virtual image A' formed at a prescribed distance on a reference line L1 by reflection from the reflection curved surface from the position where the reference line L1 and a surface normal line L2 do not match. It is sufficient that an angle formed by the reference line L1 and the surface normal line L2 at the time is large enough not to put the target A and a light source 3 in the observation optical path of the eye E1 to be tested. In such a manner, by deciding the position relation of the target A, the reflection curved surface 1 and the eye E1 to be tested so as not to match the reference line L1 and the surface normal line L2, the need of providing a half mirror in the observation optical path is eliminated.  Thus, light quantity declined due to the half mirror and the generation of the ghost images by back surface reflection are prevented.

Title: Fm receiver
Inventor: SAKATA HARUO
IPC: H04H1/00
Filed: 1994-01-28
Abstract: PURPOSE:To realize the improvement of an S/N of a demodulated base band signal by improving deteriorated S/N due to FM demodulation for the FM receiver at a weak electric field. CONSTITUTION:A frequency converter 2 converts an antenna output 1 of an FM wave into a signal of an IF frequency and the converted signal is passed through a filter 3 (filter I with a characteristic where gain is inversely proportional to frequencies). Then a subtractor circuit 4 subtracts the output of the filter 3 from the output of the frequency converter 2 to obtain the output of a filter II with a characteristic where gain is proportional to frequencies. Furthermore, the output of the filter 3 is given to a frequency discriminator 7 via a limiter 5, in which a frequency is converted into a voltage and its voltage output is fed to a narrow band pass filter group 9. Similarly the output of the subtractor 4 is given to a frequency discriminator 8 via a limiter 6, in which a frequency is converted into a voltage and its voltage output is fed to a narrow band pass filter group 10. The narrow band pass filter groups 9, 10 are sub band filters and a signal processing system 11 eliminates a noise component based on the result of comparison of output levels of the sub band filters corresponding to the outputs of the narrow band pass filter groups 9, 10 and obtains a demodulation output 12.
