Title: Error detecting and correcting circuit
Inventor: IIZUKA NOBORU
IPC: H04L27/00
Filed: 1986-08-11
Abstract: PURPOSE:To prevent the increase in an error at the reception side by inserting a parity code to the lowest string in a data of n-series at the transmission side. CONSTITUTION:A parity calculation inserting device 9' at the transmission side obtains a parity of the data of the lowest string of the n-series of input data, a parity code is inserted to the lowest position, for example, and a carrier is subject to multi-value QAM modulation by the data and the result is sent to the receiving side. The parity of the data of they lowest string in the n-series of data outputted from a balanced decoder 7 is obtained by a parity comparator 10' at the reception side and compared with a parity code inserted at the transmission side. When they are coincident, the output of the comparator 10' drives a selector 11' to output the output of the decoder 7 as it is. When they are dissident, after the output of the decoder 7 is subject to error correction by a single error correction decoder 8, the result is outputted from the selector 11'. Thus, the increase in two errors is prevented.

Filed: 1987-07-27
Abstract: PURPOSE: To provide a hand with a detecting function of the holding of the component, and prevent the attachment of the component to the finger tips when the component is released, by mounting a spring in such manner that it is passed through two fingers, and surrounds a lower side of a body, and mounting a sensor for detecting the motion in a groove at one end of the spring, on the body. CONSTITUTION: When a component exists between two fingers 3a, 3b, a U-shaped plate spring 4 is pushed upward by the component 6, and one point of the plate spring 4 is entered between the transmission type optical sensors 5, whereby the light is cut, the optical sensor 5 is switched ON, and the holding of the component 6 is detected. When the fingers 3a, 3b are opened for releasing the held component 6, the component 6 is pushed downward by the restoring force of the plate spring 4, and is forcibly separated from two fingers 3a, 3b. As the result thereof, the component 6 is not attached to the finger tips at all when the fingers 3a, 3b are opened, and the component is released just under the hand from the fingers 3a, 3b.
