摘要： PROBLEM TO BE SOLVED: To obtain a plane type curved surface mirror which is of a plane type, is always constant in a size and depth dimension, is freely variable in its focus and is capable of embodying a large focal length by discretely controlling many reflecting means which are arranged in a matrix form and deflect and reflect light in a two-dimensional direction. SOLUTION: This device comprises the reflecting means 3, a control means 4, an X-axis driving means 5 and a Y-axis driving means. The reflecting means 3 are optical scanning elements capable deflecting and reflecting the light in the two-dimensional direction by using a semiconductor process and are, for example, galvanomirrors. The reflecting means 3 are composed of the matrices of the number 1 to n in an X-axis direction and 1 to m in a Y-axis direction. The respective reflecting means 3 consist of the structures capable of arbitrarily deflecting the light to the X-Y axis. The control means 4 makes computation by the numerical value of the focal length inputted from a keyboard and executes the control of the X-Y axis to supply a X-axis driving signal Dx to the X-axis driving means 5 and a Y-axis driving signal Dy to the Y-axis driving means.

摘要： PROBLEM TO BE SOLVED: To provide a collation circuit of high reliability by having two operation means synchronous operate by the same software and having data simple to be compared and collated outputted. SOLUTION: This device is composed of microprocessor units(MPU) 1 and 2 of U and V systems which synchronous-operate and a comparison circuit 3 for comparing a comparison result output from each the MPUs 1 and 2. Each of the MPU 1 and 2 generates a ΔT interruption signal and a ΔT/2 interruption signal respectively and is synchronized and, when the ΔT interruption signal occurs, it outputs selected comparison data to other system, compares input data from the other system with the comparison contract data of its own system and outputs the comparison result output to a comparison circuit 3. Then, when the ΔT/2 interruption signal is generated, data to be transmitted to the other system is bit-reversed and, furthermore, when a specified time passes after generation of the ΔT/2 interruption signal, the comparison collation data of its own system are bit-reversed. Thus, the comparison circuit 3 has a comparison result output for indicating equality and inequality in turn transmitted from each system and, when they are matched with one another, an alternating signal for indicating a normal operation is outputted to outside.

摘要： PROBLEM TO BE SOLVED: To make it possible to reduce the cost and judge the correctness by making a digital signal processing circuit into a single system. SOLUTION: The output signal of the digital signal processing circuit 4, to which known A system and B system check signals C(A) and C(B) are added, becomes a prescribed output signal corresponding to the types of the signals C(A) and C(B) when the circuit 4 is normal. A judgement signal with effect that the circuit 4 is normal is outputted from a check circuit 5 and the output signal of the circuit 4 is used for the other unit control signal. When the circuit 4 is abnormal, the signal does not become the prescribed signal corresponding to the type of the signal C(A) and C(B) and the judgment signal with effect that the circuit 4 is abnormal is outputted from the circuit 5. The output signal of the circuit 4 is not used for controlling the other unit. The correctness of a device can be judged without constituting the circuit 4 by a multiplex system and cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To reliably detect the presence of a crossing gate lever even when the raising position of the crossing gate lever is slightly changed by a method wherein the breakage of the crossing gate lever is detected based on a sensor signal outputted from a crossing gate lever sensor. SOLUTION: A breakage detecting device 1 for a crossing gate lever is provided with a crossing gate lever sensor located in a sensor box 2 and detecting a crossing gate lever 3. The crossing gate lever sensor arranged in the sensor box 2 consists of a sensor, a switch element, a photo sensor, a magnetic sensor, and an acoustic sensor, which utilize electromagnetic coupling. The crossing lever 3 is detected and generates a sensor signal. As noted above, when the tip part of the crossing gate lever is contained in the sensor box, even when the position of the crossing gate lever is slightly changed, high damping does not occur to a sensor signal and the crossing gate lever is reliably detected.
