When an aimed word is not contained in the section 9 or when the conversion is inappropriate, the homophone order storing section 4 is then retrieved. In this case, the retrieval is made in the order opposite to the storing order. If the conversion is inappropriate or the aimed word cannot be found even when the section 4 is retrieved, a word dictionary 2 is retrieved. When the dictionary 2 is retrieved, a frequency updating section 7 and homophone selecting section 5 are actuated and the retrieval is stored in the homophone order storing section 4 and its using frequency is updated.

IPC: F16F15/08
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a vibration isolator capable of suppressing the generation of noise in the case of driving an electromagnet by a pulse signal. SOLUTION: When a switching device 13 is turned on/off by an amplitude- modulated signal corresponding to a change in vibration in the idling, a control electric signal corresponding to the amplitude and phase of vibration of a power unit is supplied from a battery power supply 14 to an electromagnet 55 mounted on an engine and an excitation board is vertically excited. Although noise is generated due to a sudden current change at the ON/OFF of a current from the power supply 14 to the electromagnet 55, the noise can be shielded by a coaxial shielding wire 15 to be a feeder directly connected to the electromagnet 55 by using a core 15a of the wire 15 as a connection line from the battery power supply 14 and using a shielding wire 15b as a connection line to be connected to the collector terminal of the switching device 13.  Consequently the occurrence of adverse effects to the operation of a computer or the like loaded on an automobile can be prevented.
