Filed: 1988-09-09
Abstract: PURPOSE:To make it possible to perform highly accurate position alignment without the effect of the inclination of the surface of a wafer and the like by providing a means and the like for detecting the position relationship between a first body and a second body along the specified direction based on the results of the detections of sensors, and detecting the position relationship which is not affected by the fluctuations of the inclinations of the first body and the second body based on said detection. CONSTITUTION:When the position of a first body 1 such as a mask is aligned with the position of a second body 2 such as a wafer, the causes of errors in detection of a deviating amount epsilonare removed. As a means for said removal, a second luminous flux as a second signal luminous flux 8 is newly formed in addition to a first luminous flux as a first signal luminous flux 7. Especially, the moving action of the incident position of the second signal luminous flux 8 on a sensor 12 with respect to the inclination of the surface of a wafer is made completely equal to that of the first signal luminous flux 7. With respect to the fluctuation of the position of an alignment head, the second signal luminous flux 8 undergoes the completely equal moving action of the incident position as that of the first signal luminous flux 7. In this way, the fluctuation of the relative positions of the second signal luminous flux 8 and the first signal luminous flux 7 on the sensors 12 and 11 depens on only the position deviation between the mask 1 and the wafer 2 in principle. Thus the highly accurate position alignment can be performed.

Abstract: PROBLEM TO BE SOLVED: To prevent service interruption state due to off-hook at the time of no-speech communication by having a speech communication detecting means and providing a circuit which avoids no-speech communication state with a receiver picked up. SOLUTION: A speech communication detection circuit 5 operates a DET relay when it recognizes voice on a general speech communication level. The DET relay of the circuit 5 operates during speech communication with off-hook, no-speech communication detection relay 9 does not operate and also it does not operate even when there is no speech communication for a short time because it is saved by a timer circuit 11. However, when there is no speech communication with a receiver picked up for a long time, the DET relay of the circuit 5 is recovered and the relay 9 through the circuit 11 operates. An idle state is shown to a station exchange 1 side when an operation relay switch 12' disconnects a direct current loop circuit between L1 and L2, a switch 12" recovers a calling circuit at the time of a call from others to enable an incoming call from the exchange 1 even with the receiver off.

Abstract: PURPOSE:To provide a complete insulation cover with ease, by covering a wire bundle with a box, and passing and binding a tightening string from a string hole through a space under the bundle to another string hole after a plurality of string holes are drilled at an inner part from an opening of an electric-wiring joint box. CONSTITUTION:A plurality of string holes 8 are drilled at an inner peripheral part from an opening 7 of an electric-wiring joint box. A wire bundle (A) is covered a box 6, and a tightening string 10 is inserted through one string hole 8 and passed along a space under the wire bundle (A) or under the step part and inserted through the other symmetrical hole 8. Both ends of the tightening string 10 are bound or fastened by hooking to prevent the box 6 from coming off the wire bundle (A) and covered in an insulated state. Since the box 6 and a mounting member 1 are separately constructed, a necessary condition that the wire bundle (A) is put just above the mounting member 1 is not required in this case. In a narrow working space for binding, the wire bundle (A) can be easily formed in a place at a distant from the mounting member 1, so the efficiency in construction can be improved.
