    • A tire burst predicting device which can predict occurrence of bursting of a tire and gives an alarm properly is provided. A break point frequency is estimated on the basis of time series data of wheel speed detected at a wheel speed sensor from frequency response of a first order model to which a transmission characteristic from a road surface disturbance to a wheel speed is approximated. A braking force gradient corresponding to the estimated break point frequency is estimated, on the basis of a map, which is prestored, representing a relationship between break point frequencies and braking force gradients. Extra high frequency components are eliminated from the estimated braking force gradient by a low pass filter to reduce estimation dispersion. Differentiators detect changing speed of the braking force gradient. An alarm is given when there is a possibility of bursting of tire when the detected changing speed reaches or exceeds a predetermined threshold value.
    • 提供一种可以预测轮胎爆裂发生并发生报警的轮胎爆破预测装置。 基于从车轮速度传感器检测到的车轮速度的时间序列数据,根据从路面干扰到车轮速度的传输特性近似的第一阶模型的频率响应来估计断点频率。 基于预先存储的表示断点频率和制动力梯度之间的关系的映射来估计对应于估计的断点频率的制动力梯度。 通过低通滤波器从估计的制动力梯度中消除超高频分量,以减少估计分散。 微分器检测制动力梯度的变化速度。 当检测到的变化速度达到或超过预定阈值时,当存在轮胎爆裂的可能性时,发出报警。

    • A photographic film cassette has a spool with a photographic film wound in a roll thereon. When the spool is rotated in a film unwinding direction, a photographic film leader is caused to advance outward from a cassette shell. The spool is constituted of two spool pieces which are rotatably and slidably coupled together via a guide shaft formed on the spool piece and a sleeve formed on the other spool piece. Each spool piece has a flange and a core. A cam follower is formed on the guide shaft and a cam groove is formed in the sleeve to receive the cam follower. The spool is thereby lengthened and shortened when the spool pieces are rotated relative to each other. Accordingly, when the spool is rotated, the flanges tightly clamp the photographic film roll laterally. The cam groove is formed so as to be closed to a core end which is coupled to the other core. A recess is formed in the inside of the sleeve, and the recess is adapted to receiving the cam follower so as to allow insertion thereof into the cam groove. The cam follower extends to an end face of a core end of the spool piece, whereby the cam follower is resistant to fracture. A pair of tongues are formed respectively on the spool pieces, and are engaged together to transmit rotation of the one spool piece to the other eve if the cam follower is broken. A projection is formed on the first spool piece, to be received by a claw formed on the second spool piece. The spool pieces are thereby prevented from being taken apart in the axial direction.
    • 摄影胶片盒具有卷轴,卷轴上卷绕有照相胶卷。 当卷轴以胶片展开方向旋转时,使照相胶卷头从盒壳向外推进。 阀芯由两个阀芯构成,该阀芯通过形成在阀芯件上的引导轴和形成在另一个阀芯上的套筒可旋转并可滑动地联接在一起。 每个卷轴件具有凸缘和芯部。 凸轮随动件形成在引导轴上,并且凸轮槽形成在套筒中以容纳凸轮从动件。 因此,当卷轴片相对于彼此旋转时,卷轴被延长并缩短。 因此,当卷轴旋转时,凸缘将照相胶卷横向紧紧夹紧。 凸轮槽形成为与被连接到另一个芯的芯端封闭。 在套筒的内部形成凹部,并且凹部适于容纳凸轮从动件,以便允许其插入到凸轮槽中。 凸轮随动件延伸到卷轴件的芯端的端面,由此凸轮从动件耐断裂。 一对舌片分别形成在卷轴片上,并且如果凸轮从动件断裂,则它们接合在一起以将一个卷轴的旋转传递到另一个前叶。 突起形成在第一卷轴件上,由形成在第二卷轴件上的爪接收。 由此防止卷轴片沿轴向剥离。

    • First and second outlet ports are connected to an inlet port. A first valve member selectively blocks and unblocks the first outlet port. A second valve member selectively blocks and unblocks the second outlet port. A first device urges the first valve member. A second device urges the second valve member. A movable member disposed between the first and second valve members allows a force of the first urging device to travel to the second valve member. The movable member can be driven by a solenoid winding. When the solenoid winding is deenergized, the first valve member is moved to its open position by the first urging device and the second valve member is moved against a force of the second urging device to its open position by the first urging device. When the solenoid winding is energized, the first valve member is moved against the force of the first urging device to its closed position by the movable member and the second valve member is moved to its closed position by the second urging device.
    • 第一和第二出口连接到入口。 第一阀构件选择性地阻挡和解锁第一出口。 第二阀构件选择性地阻止和解锁第二出口。 第一装置促使第一阀构件。 第二装置促使第二阀构件。 设置在第一和第二阀构件之间的可动构件允许第一推动装置的力行进到第二阀构件。 可动构件可由电磁线圈驱动。 当螺线管绕组断电时,第一阀构件通过第一推动装置移动到其打开位置,并且第二阀构件通过第一推动装置抵抗第二施力装置的力而移动到其打开位置。 当电磁线圈绕组通电时,第一阀构件被第一推动装置的力抵抗可动构件的关闭位置移动,第二阀构件通过第二推动装置移动到其关闭位置。
