Title: Solar radiation sensor
Inventor: TAKAHASHI TADAHIRO
IPC: G01J1/02
Filed: 1990-08-07
Abstract: PURPOSE:To obtain a solar radiation sensor which can obtain the excellent light receiving sensitivity for the light from the oblique direction even if the sensor is provided on a flat surface by forming knurling parts for irregular reflection on the inner surface of a filter that is provided at the upper surface part of the case, and setting the light receiving surface of a photodetector at the inclination of the specified angle. CONSTITUTION:A photodetector 4 of a solar radiation sensor is inclined so as to face the forward direction of a vehicle. Therefore, even if the altitude of the sun if not only high but also low, the incident solar radiation through a filter 3 can readily strike on the light receiving surface. At this time, one end of the photodetector 4 is far from the filter 3 than the other end. Therefore, the light receiving sensitivity might be impaired. Since a knurling parts 6 are arranged on the inner surface of a filter 3, however, the light passing through the filter 3 is scattered with the knurling parts 6 and strikes the light receiving surface. Thus, the excellent light receiving state is obtained. Therefore, the solar radiation sensor, characterized by the directivity for the direction other than the directly overhead direction and high light receiving sensitivity when the sensor is provided on a flat surface, is realized.

Title: Circuit for keeping polarity of pulse signal constant
Inventor: FUJIKURA TSUNEO
IPC: H03K5/00
Filed: 1987-08-26
Abstract: PURPOSE:To improve responsiveness at the time of switching the polarity of an input pulse signal, by differentiating a supplied pulse signal, generating differential pulses corresponding to a front edge and a rear edge, and operating a monostable multivibrator circuit or a bistable multivibrator circuit setting the differential pulses as trigger. CONSTITUTION:The supplied pulse signal is inputted to a pulse input terminal 1, and pulses corresponding to the front edge and the rear edge of the pulse signal are outputted by a differentiation circuit 2 as the output 4 of the differentiation circuit 2. The monostable multivibrator circuit 3 outputs pulse width a little larger than that of the supplied pulse signal setting the leading edge of the input signal as the trigger. Thereby, the circuit is triggered by the leading edge of the front edge of the supplied pulse signal, and the pulse of the rear edge is neglected since a monostable multivibration operation is performed, and a stabilized pulse with the polarity that coincides with the front edge of the supplied pulse signal can be outputted to a pulse output terminal 5. In such a way, it is possible to stabilize the polarity of an inputted pulse signal at a constant level automatically, and to improve the responsiveness at the time of switching the polarity of the signal.
