Title: Telephone system
Inventor: NISHIMURA TAKAYUKI
IPC: H04Q1/45
Filed: 1988-01-25
Abstract: PURPOSE:To simultaneously execute the sending of a tone signal and the receiving of a DTMF signal by generating a negating signal having amplitude and a phase, which are intrinsic in a connected trunk line and executing processing for eliminating a leaked tone signal. CONSTITUTION:A bidirectional amplifier is formed with a trunk line interface circuit 1, a call transformer 2, two-wire-four-wire converters 3 and 4, and amplifiers 5 and 6. The amplifier 5 is inserted into a sending side line, and the amplifier 6 is inserted into a receiving line. While a control part 10 grasps the trunk line, the control part 10 controls a tone generating circuit 8, makes the sending side signal line of the bidirectional amplifier send the tone signal through an adder 7, generates the negating signal, which has the same amplitude as that of the tone signal leaked in the receiving side signal line and an opposite phase to that of the leaked tone signal, based on a result obtained by measuring the amplitude ratio of the amplitude of the leaked signal to the amplitude of the tone signal sent by the sending side signal line of the bidirectional amplifier and the phase difference between the phase of the leaked tone signal and that of the above-mentioned tone signal by a negative signal generator 11, and adds this negating signal to a signal to be sent to a multifrequency selecting signal receiver 9 by an adder 16.

Abstract: PURPOSE:To hold the data for a long period by securing the interchangeability for transfer of data between a volatile memory (DRAM) and a hard disk device in response to the start and stop of supply of power from an external device. CONSTITUTION:When the supply of power is stopped from an external device, a processor 1 starts a data transfer processing program 1b to transfer all data stored in a DRAM 2a to a hard disk 3a. When the supply of power is started again from the external device, the processor 1 detects this restart of the power supply and starts the program 1b to transfer all data stored in a hard disk device 2a to the DRAM 2a. Thus the data can be held for a long period with no consumption of a back-up battery.

IPC: G11B5/17
Filed: 1986-01-27
Abstract: PURPOSE:To reduce the number of required land parts of a multitrack head to reduce the area of land parts by selecting heads optically. CONSTITUTION:Winding ends of winding terminal of a thin film head are concentrated and are connected to a common land part 6a for line connection similarly to connection of the end of a single electrode 4 to a land part 6.

Abstract: PURPOSE:To eliminate the mechanical process distortion layer on the surface of the base plate by processing the lithium tantalate into the flat board type base plate and then giving etching process to the both surfaces of the base plate after the lapping process. CONSTITUTION:The etching is given to both surfaces of the lithium tantalate base plate featuring, for example, the thickness of 75.5mum and the resonance frequency of 27.28MHz each after the lapping process according to the sizes of the abrasive grain as #1200, #2000 and #4000 each. With the size of the abrasive grain used as the parameter, the curves are drawn with the etching amount and the resonance resistance set to the horizontal and vertical axes each. Thus the resonance resistance lowers down suddenly along with the progress of the etching in the case of size #4000. And the best product is obtained when the lapping is given with the size #4000 of the abrasive grain.
