摘要： PURPOSE:To shorten a time used for confirming operation of self diagnosing by displaying the name and state of controlling signals on the same picture. CONSTITUTION:A PC main arithmetic section 81 is provided with an arithmetic main body section 81a that calculates control of the whole PC8, a judging section 81b that judges whether a diagnosis request flag designated by an input/ output section 12 is set to a common use memory 9 or not, a reading section 81c that reads an address from the common use memory 9 basing on the result of judgement of the judging section 81b and a comparing section 81d that judges whether the address read by the reading section 81c is the same with the content of last time or not. Basing on judgement of the comparing section 81d, only the status signal of a PC local memory 82 is set to the common use memory 9, or status signals of signal name data of a data memory 19 for display and the PC local memory 82 are set to the common use memory 9.

摘要： PURPOSE:To protect a solenoid exciting circuit and to confirm a failed solenoid valve quickly and properly by detecting a voltage between output triac terminals of an SSR so as to protect the solenoid exciting circuit employing the SSR and sending an alarm signal to a PC at the occurrence of a fault. CONSTITUTION:If a solenoid valve driven by a solenoid 8 is faulty and an overcurrent takes place in the solenoid, a voltage between terminals 11 of a triac 10 rises and it is detected by a voltage detection section 16 through the terminal 11. When the detected value is more than a reference voltage for circuit protection set by a reference section 17, a transistor of an output driver 19 is turned on by a comparison section 18 and an alarm signal is sent to a PC input section 21. In receiving said alarm signal, the PC input section 21 activates an alarm processing program to turn off a PC output exciting a relay coil 22. Further, which solenoid valve hes a fault is discriminated by the input address of said alarm signal at the same time.

摘要： PURPOSE:To minimize the influence of the bias current of a differential amplifier as an inversion-noninversion switching circuit upon its output and to obtain high accuracy by switching the differential amplifier which uses an operational amplifier in synchronism with the change of the polarity of an input signal. CONSTITUTION:An analog switch 13a is connected to its upper terminal as shown by a solid line and an analog switch 13b is connected to its right-side terminal, so that the differential amplifier 10 operates as an inverting amplifier whose gain is -1. Further, the analog switch 13a is connected to the lower terminal and the analog switch 13b is connected to the left-side terminal, so that the amplifier becomes a noninverting amplifier whose gain is 1. Namely, the input analog signal V1 is inputted to a polarity detector 14, which outputs an analog switch control signal d0 synchronized with the change of the polarity of the input analog signal V1. Then, the connections of the analog switches 13a and 13b are so controlled with the analog switch control signal d0 that the polarity of the input analog signal V1 is uniform, thereby switching the differential amplifier 10 between the inverting amplifier and noninverting amplifier.

摘要： PURPOSE:To shorten the time required for console panel generation by substituting a console panel with operation key switches by a key specification switching means. CONSTITUTION:When the key 'CHANGE' of the key specification switching means is on, bit information of an operation key switch is supplied from an NC device 1 by input processing and a user generates a sequence program on the basis of the information. When the key 'CHANGE' is on, the NC device 1 supplies the key information, but disables operations and when off, the operations are possible, but the key information is not supplied. A key function picture setting means 8 moves a cursor 9 with keys ' ', 'z', ' ', and ' 'and the setting is completed by pressing an 'INPUT' key after keys for the setting are pressed.

摘要： PURPOSE:To move a cursor as desired with the least number of times of operation even if an operation range is small by detecting an operation speed from the output increment data of a pointing device and calculating a cursor movement quantity corresponding to the speed. CONSTITUTION:The increment data outputted by the pointing device is sampled by hardware or software to detect the operation speed. Then the increment data obtained within a sampling interval is multiplied as specified according to a speed section to obtain the cursor movement quantity. Consequently, even if the cursor movement quantity varies according to the operation speed and even if the operation range is small, the cursor is moved to a desired position with the least number of times of operation.

摘要： PURPOSE:To eliminate the necessity of the setting of the barrier data by an operator at each time even when a work is changed by inputting barrier data used for working of the work from the processing program. CONSTITUTION:When a barrier data input instruction (barrier instruction) is commanded, a barrier data input instruction decoding means 16 detects the code, starts the barrier instruction decoding processing, and the data continuous to the coordinate word are written to the applicable address by the coordinate word continuous to the code while the address of a barrier data table 31 in a memory part 12 is designated by a barrier data writing means 17. The processing is successively executed concerning all coordinate words. On the other hand, an arithmetic part 1 designates the address of the table 13 stored by a barrier data address designating means 11 and fetches the barrier data through a data reading means 14 to a deciding circuit 15. The deciding circuit 15 compares the tool position command data processed by the arithmetic part 1 and the barrier data, and when the command is troubled, the command is stopped and the alarm is issued.

摘要： PROBLEM TO BE SOLVED: To supply a machining material by opening and closing a collet chuck while rotating a main spindle motor in an automatic lathe for gripping the machining material (a bar) by the collet chuck for machining. SOLUTION: A magnetostrictive element 36 and an exciting coil 37 for surrounding this element are embedded inside the collet chuck. An exciting power source between a main spindle frame body 1b and a hollow main spindle 6b is supplied in a noncontact state by a rotary transformer. Output of a hollow main spindle 6b side secondary winding 40 is rectified and smoothed to be converted into DC exciting voltage. The hollow main spindle 6b and the collet chuck 3b are mutually connected by respectively arranged exciting voltage electrodes 45 and 46 and wiring. A magnetic field is generated by impressing the DC exciting voltage on the exciting coil 37. Shaft directional elongation of the magnetostrictive element 36 by impression of this magnetic field is amplified and converted into the action force in the work 2 central direction of the collet chuck 3b. A work can be supplied by opening and closing the collet chuck without adding an exclusive opening-closing motor.

摘要： PROBLEM TO BE SOLVED: To provide a collet chuck opening/closing device that can open and close a collet chuck while keeping a spindle rotor rotated, and can improve productivity via continuous machining on work. SOLUTION: A collet chuck 5 for holding work 6 on the internal surface is rotatively driven by a spindle motor 2 via a hollow main spindle 3. A cylindrical opening/closing sleeve 4 rotatively driven by an opening/closing motor 10 is rotatably fitted around the external surface of the collet chuck 5. A difference in rotational frequency between the spindle motor 2 and opening/closing motor 10 causes the opening/closing sleeve 4 to rotate relative to the collet chuck 5, with the result that scrolled internal cam portions with a circumferentially changing inside radius formed over the internal surface of the opening/closing sleeve 4 changes the radial position of the external surface of the collet chuck 5 and moves the internal surface of the collet chuck 5 radially to open or close the collet chuck 5.
