Filed: 1985-05-22
Abstract: PURPOSE:To obtain an optical current transformer which has a compact sensor while solving problems of insulation and manufacture cost by providing an incidence and projection part for light nearby the center part of a side of a polygonal Faraday cell. CONSTITUTION:Light emitted from a light source 2 through a light source driving circuit 1 is transmitted by an optical fiber 4 and collimated by a collimator lens 14 into parallel light, which is polarized linearly by a polarizer 12. This linear polarized light passes through a path shown by a broken line and reflected totally and repeatedly as shown by (k), (l), (m), (n)... to travel circulating in the conductor 10 in the Faraday cell 31, so that the light is separated into two light components through an analyzer 13. One light component is incident on an optical fiber 7a through a collimator lens 15a and the other light component is incident on an optical fiber 7b through a right-angled prism 32 and a collimator lens 15b. Then, they are converted photo-electrically by photodiodes 5a and 5b and processed by a signal processing circuit 6, which outputs a voltage proportional to a current to be measured.

IPC: H04N1/23
Filed: 1984-05-30
Abstract: PURPOSE:To realize the highly faithful reproduction of recording information having medium density such as a video signal, by appropriately selecting a voltage detection terminal corresponding to the current supply state to a heat generating element and detecting voltage applied to a heat generating resistor to feed back the same to a power source. CONSTITUTION:The switch of a heat generating element driven by an external signal source is provided in a thermal recording head 2 and the heat generating element is appropriately selected corresponding to an external signal to receive the supply of a current. At this time, voltage, which is applied to the heat generating element from a plurality of voltage detection terminals 4 provided to the common electrode for supplying a current to the heat generating element by a falling voltage detection circuit 5, is detected and fed back to a power source 1 to control voltage applied to the heat generating element from the common electrode so as to make the same constant. Because the quantity of energy per one element applied to the heat generating element in the thermal recording head can be made constant regardless of the number of elements driven simultaneously, highly accurate medium density recording can be performed stably.

Filed: 1990-04-24
Abstract: PURPOSE:To judge the presence of a slip by comparing the speed of a inner wheel detected by the first speed detection means corresponding to the steering angle or car speed of a turning vehicle with the speed of a outer wheel detected by the second speed detection means. CONSTITUTION:For example, when a vehicle turns left, a left rear drive wheel 2a corresponds to a inner wheel and a right rear drive wheel 2b corresponds to an outer wheel. The speed Vtaul of the drive wheel 2a is detected by the first speed sensor 1a and the speed Vrr of the drive wheel 2b is detected by the second speed sensor 1b and the speed difference between both wheels is calculated. For example, the speed difference between the inner and outer wheels is judged to be smaller than 0, it is judged whether the absolute value of this speed difference is larger than a reference value. That is, when the speed of the drive wheel 2a corresponding to the inner wheel exceeds that of the drive wheel 2b corresponding to the outer wheel as compared with such a case that the drive wheels 2a, 2b are respectively rotationally driven in the normal number of times and also exceeds the speed difference reference value calculated corre sponding to the steering angle or car speed at that time, it is judged that a slip is generated in the drive wheel 2a.
