    • A method of manufacturing a liquid ejecting head that ejects a liquid supplied from a liquid storing member through a liquid supply path. The method includes positioning a filter to a first or second supply member by using positioning pins upon disposing the filter between first and second liquid supply paths. The first supply member has the first liquid supply path. The second supply member has the second liquid supply path on the side of one surface of the first supply member to communicate with the first liquid supply path. At least the first supply member and the second supply member are integrated such that a fixed portion is molded by injecting a resin material from an injection portion of a mold at a position where the first and second liquid supply paths are interposed between the positioning pins.

    • An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.

    • Provided is an echo canceller capable of realizing an excellent echo cancellation performance even in a double talk state. An echo canceller (10) comprises: an adaptive filter (20); a subtractor (30); and an error signal generating circuit (40). The adaptive filter (20) synthesizes a spurious echo signal (y′(k)) from a receiving signal (x(k)) before being delivered from a speaker (3). The subtractor (30) subtracts the spurious echo signal (y′(k)) from an input signal (yin(k)) received by a microphone (2) so as to generate an echo cancellation signal (p(k)) The error signal generating circuit (40) generates an error signal (s(k−1)) by removing a spurious voice signal (r(k−1)) corresponding to a voice signal (v(k)) of a talker from the echo cancellation signal (p(k)). The adaptive filter (20) updates a characteristic of the adaptive filter (20) so that an amplitude of the error signal (s(k−1)) becomes smaller.
    • 提供了即使在双方通话状态下也能够实现优异的回波消除性能的回波消除器。 回声消除器(10)包括:自适应滤波器(20); 减法器(30); 和误差信号发生电路(40)。 在从扬声器(3)传送之前,自适应滤波器(20)从接收信号(x(k))合成寄生回波信号(y'(k))。 减法器(30)从由麦克风(2)接收的输入信号(yin(k))中减去寄生回波信号(y'(k)),以产生回波消除信号(p(k))。误差 信号发生电路(40)通过从回声消除中去除与讲话者的语音信号(v(k))相对应的杂散语音信号(r(k-1))来生成误差信号(s(k-1) 信号(p(k))。 自适应滤波器(20)更新自适应滤波器(20)的特性,使得误差信号(s(k-1))的振幅变小。
