IPC: H04Q3/58
Filed: 1989-04-27
Abstract: PURPOSE:To attain accurate changeover an incoming extension for day and night by identifying tenant information from a set extension designation signal itself and switching the incoming extension depending whether the tenant is in the daytime mode or the night mode. CONSTITUTION:When an office line trunk circuit 8 of a tenant 1 detects an incoming call, a central processing unit 6 designates it to a switch 5 to connect the circuit 8 and a PB register circuit 4. In this state, the extension designation signal 12a sent to the circuit 8 from the station side is received by the circuit 4 and transferred to the unit 6. Thus, the unit 6 uses the tenant information set in advance in a main storage device 7 from the signal 12a to recognize the signal 12a to be the extension designation signal of the tenant 1. Moreover, the unit identifies it from the state of an external key 10 of the tenant 1 that the tenant 1 is in the night mode and switches the connection between the extension B and the path F of the circuit 8 being the night incoming extension of the predetermined tenant 1 into the connection of the path G.

Abstract: PURPOSE:To minimize the variation of the set value of the core gap at the time of heating and cooling in the stage of manufacturing a magnetic head, by putting a block, plural core materials and one or plural gap adjusting blocks between the 1st and 2nd fixing base bodies.

Filed: 1981-07-06
Abstract: PURPOSE:To correct the bent scanning locus to a straight line, by utilizing inversely the phenomenon that the bright line of the spectrum is bent when a spectrum image is expanded with a prism. CONSTITUTION:A point O is the light incidence point on a refracting face F. A beam PO is refracted to become a beam Oq. A line L which passes a point P and is parallel with the face F and is orthogonal to the line PO, a line L' which passes a point (q) and is parallel with the line L, and a face F' which includes the point (q) and is parallel with the face F are considered. When the point P is brought to the infinity along the line L in the direction of an arrow, the angle of refraction becomes a critical angle theta, and the refracted light becomes a beam OR. The locus of intersections between the face F' and the refracted light in the course where the point P is brought to the infinity along the line L becomes a curve connecting points (q) and R and is deviated from the line L' in accordance with the distance from the point (q). This phenomenon occurs in the same direction on both of the incidence face and the exit face of a prism, and the prism is directed properly to cancell the bending of the scanning locus L. The diffracted light is refracted by the action of a prism 5 as a correcting means, and an object face 4' is moved to a position 4 actually.
