Abstract: PURPOSE:To decide whether or not the connection is to be confirmed automatically based on the detection of polarity inversion without requiring any switch operation by controlling whether or not the connection is to be confirmed by the detection of polarity inversion in response to caller information used through the reference of a table memory at calling. CONSTITUTION:A table memory 4 comprising a RAM or an EEPROM is connected to a control section 3 and the table memory 4 stores call information used for a call and information as to whether or not the connection is to be confirmed by the detection of polarity inversion at a call to an opposite station represented by the call information relating to each other. Then the table memory 4 is referenced at calling to control whether or not the connection by the detection of polarity inversion is to be confirmed in response to the call information in use. Thus, whether or not the connection is to be confirmed by the detection of polarity inversion is decided automatically without need of switch operation or the like.

Title: Method for measuring length of yarn and detecting constant length wind-up and end breaking in winder process of spinning
Inventor: NOMURA TADAO
IPC: D01H13/14
Filed: 1987-10-14
Abstract: PURPOSE:To facilitate the measurement of the length of yarn by integrating the number of times at which the yarn is reciprocated on a drum surface with the length of one reciprocation on the drum by the yarn at the time of winding up the yarn which is wound on one pipe to the other pipe via the drum having guide grooves on the whole width of its peripheral face. CONSTITUTION:Yarn A wound on a pipe shaft 11 is wound up on a pipe shaft 12 via a photo-sensor 1 and the grooves 14 of a drum 13 having the guide grooves 14 on the whole width of its peripheral face. From the number of times at which the yarn A passed through the photo-sensor 1, the number of times at which the yarn A is reciprocated through the guide groove 14 of the drum 13 is inputted into a counter 2, and this number of reciprocations is integrated with the previously obtained length of the one reciprocation of the yarn A, to obtain the length of the yarn A and indicate 3 it. Also, if the delay of input into the counter 2 is detected by e delay circuit 5, it is judged end breaking and a stop signal 6 is outputted. When a defined length is indicated on an indicating part 3, the stop signal 6 is outputted. Thereby, measurement of length and constant length wind-up can be carried out only with one photo- sensor enabling emergency stop at the time of cutting, and simplifying a structure.

Abstract: PURPOSE:To recognize an obstacle on a running course based on a comparison result by providing a means which compares the picture fetched in by a picture input means at the time of turning on one light throwing means with that at the time of turning on the other. CONSTITUTION:An illumination switching part 6 turns on an A illumination part 2 to fetch the picture of an A frame picked up by a picture input camera 1 into a picture memory 4. The switching part 6 turns on a B illumination part 3 to take the picture of a B frame picked up by the camera 1 into the memory 4. A picture processing part 7 discriminates whether the number of taken-in picture frames reaches a prescribed value or not. When it reaches the prescribed value, an average picture (A illuminated picture) of A frame pictures is calculated, and that (B illuminated picture) of B frame pictures is calculated. Both pictures are different only by sizes of shadows 11a and 11b of an object on the road surface as the comparison result. Thus, a main control part 8 decides the object 11 as a projection, namely, an obstacle on the road surface based on the result of comparison between the A illuminated picture and B illuminated picture.
