Title: Communication system
Inventor: HIRAI JUN
IPC: H04M1/53
Filed: 1992-08-31
Abstract: PURPOSE:To send destination information and additional information by allowing an exchange to discriminate the destination information and additional information through hooking by implementing hooking so as to indicate a delimiter of each information and an end of all information thereby entering a hooking signal. CONSTITUTION:In an exchange 1 accommodating a dial pulse type telephone set 2, when additional information is entered in succession to destination information entered by a telephone set 2 at dialing, hooking is implemented to indicate a delimiter of each information and the end of all information to input a hooking signal to allow the exchange 1 to add the additional information to the destination information and to send the resulting information. The hooking signal uses a maximum of a DC loop interruption time allowed as a brake time of a dial pulse for a lower limit threshold level and uses a minimum of the DC loop interruption time allowed as an on-hook for an upper limit threshold level, and the signal whose DC loop circuit interruption time by hooking is in existence between two threshold levels of upper and lower limits is used for the hooking signal.

Title: Thin film magnetic head
Inventor: KATAHASHI HISASHI
IPC: G11B5/31
Filed: 1990-09-05
Abstract: PURPOSE:To obtain a thin film magnetic head with a satisfactory reproducing output by providing a dielectric film having a film surface almost parallel to the opposite faces of first and second magnetic cores between both cores. CONSTITUTION:Signal magnetic flux in reproduction tries to flow as shown by a broken line and leakage magnetic flux between the upper and lower magnetic cores tries to flow orthogonally to the film surface of a conductor film 7. Therefore, when the signal magnetic flux is a high frequency, an eddy current flows in the conductor film 7 parallelly to the film surface as shown by a white arrow in the figure, and magnetic flux is generated in a direction to cancel the leakage magnetic flux as shown by a black arrow in the figure. Therefore, the magnetic flux is prevented from leakage between the upper and lower magnetic cores. Generally, the reproducing output of the magnetic head is lowered especially by the high frequency caused by the high frequency loss of a core material or a spacing loss when a medium is slid. Thus, by decreasing the leakage magnetic flux by the high frequency as mentioned above and increasing the reproducing output, the satisfactory head output can be obtained over all the bands.
