Filed: 1995-11-21
Abstract: PURPOSE: To enable a sound-sensitively handicaped person, who an supplementa tion phenomenon appears in the low sound band more strongly than in the high sound band to use pleasantly by giving such frequency characteristic to an output limiting circuit that the output sound pressure level of the high sound band is reduced. CONSTITUTION: A series impedance circuit IMP consisting of a capacitor Cl and a resistor R1 and a compressing circuit COMP consisting of a pair of diodes D1 and D2 connected in parallel in opposite directions are connected between the collector and the base of a transistor TR Q1 for amplification of an output limiting circuit 2. A hearing aid voice input is applied between a base terminal T1 or the TR Q1 and a connection terminal T3. When the frequency is increased, the input impedance of the capacitor C1 is reduced, and the output sound pressure level in the high sound band of a receiver 1 is suppressed. Thus, it doesn't exceed a discomfortable value in the high sound band, and the sound pressure level is not suppressed in the low sound band which the supplementation phenomenon doesn't appear, thereby generating the practically sufficient sound pressure level from the receiver 1.

Abstract: PURPOSE:To facilitate multi-gradation representation, by constructing with a plurality of pair electrodes having total width shorter than the effective recording width of heating elements and controlling the time for applying voltage onto the heating elements and the number of pair electrodes being employed for application of voltage. CONSTITUTION:A joint of an electrode 2 with a heating element 1 consists of a plurality of pair electrodes 2-1, 2-2, 2-3 having total width shorter than the effective recording width of said heating element. When the current level is lower than a predetermined level, almost all current flows to a lateral portion of the heating element 1 corresponding to the width of pair electrode 2-2 being applied with voltage; thereby, the temperature at said lateral portion increases particularly and the temperature difference between said lateral portion and other portions increases. When applying time of pulse voltage is increased gradually in order to vary the applying energy. ink is fused in an area hazing higher temperature th.n the melting point of an ink sheet and transferred to a recording sheet. Consequently. the area of dot being transferred can be varied by varying the pulse voltage application time and the number of driving electrodes, resulting in smooth modulation of dot area.
