Abstract: PURPOSE:To always cut a work orthogonally with prescribed dimensions by providing a sensor in the work feed direction and bringing it into contact with the work to position and converting the moving quantity of the sensor into the voltage and moving a machining head orthogonally to the work feed direction when the voltage attains zero. CONSTITUTION:A differential transformer 2 is set on the intermediate position of the moving range of the sensor 1 so that a voltage level attains zero. The voltage level attains zero at a point of time when the work 5 to be fed comes into contact with the sensor 1 and the distance between the sensor 1 and the machining head 3 at this time is made to cutting dimensions of the work 5. Accordingly, when the sensor 1 is pressed strongly by the work 5, the voltage level of the differential transformer 2 breaks but the distance between the sensor 1 and the machining head 3 which is made to the prescribed cutting dimensions is set on a control means, so it is corrected by a driving motor 4 so that the voltage level attains zero. A voltage level zero signal is outputted from the differential transformer 2 to the control means and a laser beam is projected from the machining head 3 which is moved in the orthogonal direction to the work feed direction to out the work 5.

IPC: H04L9/00
Filed: 1984-12-05
Abstract: PURPOSE:To suspend data transmission when erroneous connection is generated in a communication circuit system and to enable protection of secrecy between companies by providing an inherent identification code in terminal controlling devices and making a host device transmit the identification code prior to transmitting data to be transmitted to the terminal controlling device. CONSTITUTION:In the case where interchanging between a circuit connecting section 7 and MODEMs M1, Mn is generated by mistake, when a CPU1 is going to transmit datat o a TCE4 of a company A, a power source of a TCE4 of a company N is turned on by a command of power source application from the CPU1 to complete preparation. When the CPU1 is going to transmit an identification code to the company A, it is sentto the TCE4 of the company N. The TCE4 of the company N returns a reply of data transfer impossible as its own identification code is different in received identification code. The CPU1 recognizes that erroneous connection is generated, and suspends data transmission to the company A. Thus, passing of data of the company A to other companies can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent excessive bending of a connecting part by introducing a buckling degree by measuring pushing-in force to a propelling pipe connected so as to be freely bendable and a backing quantity when the pushing-in force is released with the lapse of time, and setting allowable maximum pushing-in force. SOLUTION: A propulsion body S is sandwiched by a sandwiching mechanism 14, and a longitudinal movement of a propulsion driving mechanism 15 in the lengthwise direction of a propulsion pipe 2 is detected by a stroke sensor 16. A buckling quantity of a length in which the propulsion body S returns when pushing-in force to the propulsion body S is released, is measured by a buckling sensor 17. The pushing-in force is also measured with the lapse of time by a propulsion sensor 18. The total of a buckling quantity is subtracted from the extension of accumulative pushing-in strokes of the stroke sensor 16, and a propulsion length L of the propulsion body S is found. A pushing-in force changing point is detected from the relationship between the propulsion length and the pushing-in force by a measuring result with the lapse of time of the propulsion sensor 18.  A buckling degree by dividing a backling quantity at the pushing-in force changing point by the propulsion length is introduced, and allowable maximum pushing-in force is set low as the buckling degree is large.
