摘要： 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.

摘要： 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.
摘要翻译： 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。

摘要： An instant film pack includes a plurality of instant photo films. A case contains the instant photo films being stacked. An exit slot is formed in the case, for exiting the instant photo films to an outside of the case one after another. A claw path opening is formed in the case, for receiving insertion of an advancing claw mechanism for advancing the instant photo films by one photo film to move to the exit slot. A thrust preventing flap is disposed on an inside of the exit slot, for closing the exit slot at the middle, to prevent the instant photo films from coming through the exit slot. Furthermore, a light shielding sheet of aluminum foil closes the claw path opening in a light-tight manner, and is released to open the claw path opening upon advance of the advancing claw mechanism.

摘要： 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.

摘要： In a tire air pressure estimation based upon vibration components extractedrom a vehicle wheel speed signal, when the vehicle is a driven vehicle wheel, the precision of estimation is improved by canceling the components of vibration due to the resonance of the drive system from the vibration components based upon which the estimation calculation is made. The vibration components due to the resonance of the drive system can be canceled by canceling those vibration components extracted from the vehicle wheel speed signal which are the same in the phase between left and right driven vehicle wheels. When the tire air pressure of one of a pair of left and right driven vehicle wheels is lower than that of the other, the lower tire air pressure is more correctly estimated. Therefore, the higher tire air pressure may be estimated according to the lower tire air pressure against the drive system resonance.
