Title: Tool positioning and rapid return device of ordinary lathe
Inventor: HIRANO YOSHIKIYO
IPC: B21H3/04
Filed: 1979-04-13
Abstract: PURPOSE:To make possible working, particularly thread-rolling without using any intricate mechanism by working the material by the tool on the tool rest which is slidable in the cross feed direction on the cross slide of an ordinary lathe, detecting the top dead point position upon completion of the working and rapidly returning the tool rest by springs. CONSTITUTION:A carriage 1 is positioned and stopped and the work is gripped with a chuck 47. While the work is being rotated, a cross slide 3 is fed in the A direction. The pawl 21 of a slide bed 4 is engaged with the recess 24 of the locking plate 14 secured to a tool rest 8 and the rest 8 moves together with the bed 4 in the A direction against the springs 42 with a stationary member 13. The thread rolling head 7 on the rest 8 is pressed to the work, whereby the work is rolled. At this time, a pawl control plate 18 is held secured and static to the member 13 and therefore a pin 25 moves in the A direction while making slide contact with a surface 26. When the head 7 comes to the top dead point, the pin 25 is moved by the cam surface 27 of the plate 18 and the pawl 21 is gradually disengaged from the recess. Further, when the vertex of the triangle protrusion 28 of the engaging plate 29 of the pawl passes the vertex 31 of the engaging part 31 of a pawl locking member 32, the engagement of the pawl 21 is quickly removed by the sping 33 force and the rest 8 is returned in the B direction by the spring 42 force.

IPC: G06F3/041
Filed: 1992-03-02
Abstract: PURPOSE:To easily secure the expending performance for setting a state and also to simplify the circuit constitution by mounting many switches to a position pointer. CONSTITUTION:The electromagnetic connections M1 and M2 are produced when a resonance circuit 4 provided to a position pointer 5 gets close to the 1st and 2nd connecting means 1 and 2 respectively. Thus, a positive feedback loop is formed with a series of paths consisting of the output of an amplifier circuit 3 and the inputs of the means 1, the connection M1, the circuit 4, the connection M2, the means 2, and the circuit 3 respectively. Then, the oscillation is produced with the resonance frequency of the circuit 4 and an oscillation signal 101 is obtained. The amplitude of the signal 101 varies according to the position of the pointer 5. Thus, a position detecting circuit 6 acquires the position information on the pointer 5 based on the amplitude of the signal 101. Then, a state detecting circuit 8 can detect the information on both switches SW1 and SW2 set by a state setting circuit 7 based on the frequency of the signal 101.

Abstract: PURPOSE:To prevent a called party from being troubled by calling a called party when a voice reaches from a caller within a prescribed period after automatic reply and interrupting an incoming call automatically when an in-band signal other than the voice reaches from the caller within a prescribed time or the in-band signal does not reach. CONSTITUTION:When an incoming call comes to a telephone set, a CPU 13 closes a loop switch 2 to form a DC loop to a subscriber line and displays a reply to the incoming call to an exchange. When a caller intends to make a silence call, no reply comes with respect to a reply message within a prescribed time. The state is detected as a silent state by a voice presence detection circuit 10 and it is reported to the CPU 13. In recognizing the state, the CPU 13 discriminates it as a troublesome call, the loop switch 2 is opened without starting an alerting circuit 9 to interrupt the DC loop thereby informing the end of call to an exchange from the incoming side. That is, the called party drives out a troublesome call without being troubled by a silent call.
