Title: Analog telephone set switching system
Inventor: KITAJIMA RYUICHI
IPC: H04M11/00
Filed: 1984-10-23
Abstract: PURPOSE:To improve the economical efficiency of a digital exchange by switching a transmission line for a digital exchange to a transmission line of digital information through which an analog telephone set transmits and receives with a digital exchange through an analog telephone controlling circuit. CONSTITUTION:When a switching circuit 10 is set to the state of connecting an analog telephone set 8 to a subscriber's line, no more digital information sent from a data circuit interface device 6 arrives at a circuit controlling circuit 11. Consequently, a synchronism detecting circuit 112 detects out-of-synchronism, and transmits a detection output to a selector circuit 114. The circuit 114 that received the detection output releases a transmission line between the circuit 111 and a network 2 and sets a transmission line between an analog telephone controlling circuit 113 and the network 2. After this, the telephone set 8 is connected to the circuit 113 through a switching unit 10 and the subscriber's line 7, and analog voice information sent and received by the telephone set 8 is converted to digital information in the circuit 113, and transmitted and received between the network 2.

Title: Magnetic-optical recorder
Inventor: YOMO MAKOTO
IPC: G11B5/02
Filed: 1992-08-21
Abstract: PURPOSE:To prevent the quality of a recording pit from being lowered due to a leakage magnetic field by reading out a current value in accordance with a prescribed position stored in memory, and applying a current to offset the leakage magnetic field by a leakage magnetic field offset means. CONSTITUTION:The relation of an applied current and a disk radius position is stored in the memory 18 by precisely measuring the distribution of the leakage magnetic field in advance. When information is recorded on a magneto- optical disk 1, the applied current IA in accordance with the disk radius position is read out from the memory 18, and it is transmitted to an offset generation circuit 19, and the circuit 19 permits the current IA to flow on a coil 20, and an offset magnetic field is generated in an electromagnet 21, then, the recording of the information is started. By employing such constitution, it is possible to supply the offset magnetic field to negate the leakage magnetic field at any position where an optical head 5 is located and to eliminate the influence of the leakage magnetic field by an inexpensive means and to precisely form a recording signal as the recording pit.
