IPC: H03K17/95
Filed: 1981-06-02
Abstract: PURPOSE:To obtain a stable output signal at the parting of a body to be detected, by supplying a current of AC component with a prescribed frequency and amplitude to an oscillation circuit of a proximity switch and regulating the oscillation condition of the proximity switch with the current of AC component. CONSTITUTION:An oscillation circuit 1 is provided with a parallel resonance circuit consisting of a coil 4 and a capacitor 5 and a current mirror circuit in which an output current determined with an active current value of a transistor TR8 is generated from a TR9 and given to a parallel resonance circuit. The active current value of the TR8 is determined corresponding to a parallel circuit generating voltage and the oscillating voltage of the circuit 1 is compared with a comparison voltage at a comparison circuit 2. On the output current of the TR8 determined with the comparison circuit 2, a current including the AC component of an AC power supply 15 with a prescribed amplitude and frequency is superimposed. Thus, the start of oscillation after the parting of a body to be detected is made from a prescribed amplitude, allowing to remarkably reduce the delay time until the output is inverted after the parting of the body to be detected.

Title: Code error detection/correction device
Inventor: AOKI NORIO
IPC: H04L1/00
Filed: 1978-07-12
Abstract: PURPOSE:To secure the correction for the code error featuring the highest occurrence frequency by memorizing the data equivalent to the adjacent two clocks through the bipolar PCM code decoder circuit and then opening the gate by these two output ot generate the detection signals when the code error occurs. CONSTITUTION:The level comparison is carried out via comparator 1 and 2 between reference voltage VR1/VR2 and PCM reception signal S in order to obtain the + and - code output. These code output are then applied to n-nit shift register 3 consisting of n-units of D-FF to which timing extracting clock pulse (c) is applied. For the bipolar PCM code, the same code of 1 or - never continues by more than two clocks. Thus, in case the output of NAND gate 4 to which every adjacent two bits are supplied is O, some error exists to produce error detection information (e). When this signal is delivered from gate 4 or 4', corresponding FF5 and 5' are cleared forcedly to secure the output of O. Thus, the error can be corrected.
