Title: Displacement detector
Inventor: HAYASHI AKITAKE
IPC: G01C9/06
Filed: 1990-08-10
Abstract: PURPOSE:To simplify a structure and miniaturize a displacement detector by a method wherein a returning means rotates a container to constantly keep a movable member at a reference position and also a displacement detecting means detects a relative position between a member whose displacement is to be detected and the container. CONSTITUTION:A vacuum container 4 whose rotation is controlled only by a servo motor 2 does not rotate with respect to an outer package 1. A movable member 8 keeps an original azimuth or position by inertia. As a result, the member 8 rotates relatively to the container 4 and the outer package 1. When the member 8 rotates, outputs from light detectors 14a, 14b are monitored by a control circuit 16, and when difference in the outputs is a determined value or higher, a shift of the member 8 from a reference position is determined and a direction of the shift is identified depending on whether the difference is positive or negative. The motor 2 is driven by the circuit 16 according to the result, and the member 8 is returned to the reference position with respect to the container 4. Thus if a rotation amount of the container 4 is monitored by a rotation encoder 18, angular displacement can be easily detected.

Title: Decoder
Inventor: IWASAKI JUNICHI
IPC: H03M7/00
Filed: 1987-08-26
Abstract: PURPOSE:To attain normal operation as a decoder by providing plural product- term line groups of the same logic and a logic arithmetic unit for logic operation of the outputs and using the logic arithmetic unit so as to correct the result of decoding outputted in error by a fault of a product-term line in the product-term lines. CONSTITUTION:Suppose that an AND gate 127 is in error and an output of an output line 112 is independent of the input value of an input line 103. In receiving an input signal 0002 in this case, since the output line 113 is inactive because the input of the AND gate 130 is 0, the output line 117 being AND of output lines 112, 113 is inactive. Since the output is only the output line 116 being the correct result of decoding to the input 0002 finally, it does not cause any malfunction. Thus, even if a fault exists in a PLA of the decoder, only when even one PLA output of the other same logic is normal, no malfunction takes place and the reliability is improved considerably.
