    • PURPOSE:To prevent separation due to pressure difference between inside and outside a combustion chamber, by furnishing a nozzle closure with a draft hole, which puts inside and outside the combustion chamber in communication, and with a filter. CONSTITUTION:A nozzle closure 4 formed from elastic substance such as rubber has a circular block part 4a and a righ-shaped mounting part 4b. This block part 4a is provide with a draft hole 4c opening to both sides, and its surface on the mounting side 4b is equipped with a filter 11 which has water repulsiveness and air draughtiness and which shelters said draft hole 4c. On the ground this filter 11 hinders intrusion of air moisture into the combustion chamber 5, and air therein is exhausted via said filter 11 and draft hole 4c while this multi-stage rocket in concern is in its up position, and thereby the nozzle closure 4 is prevented from separating from nozzle 3 due to pressure difference between inside and outside. After opening the head of a nose fair ring, the nozzle closure 4 is separated from the nozzle 3 by the pressure of combustion gas of a solid thrust powder 7.

    • PROBLEM TO BE SOLVED: To decrease heat load to a thrust deflector or improve a thrust effi ciency by providing at regular intervals on the outer periphery of a rocket nozzle prescribed number of thrust deflectors for deflecting the jet of combustion gas about orthogonal two axes perpendicular to a body axis and about the body axis. SOLUTION: A rocket A is provided with a rocket nozzle 2 and a protruding part 3 in a motor case 1 loaded with a solid propulsive powder. Four thrust deflectors 4 are rotatably attached to the outer periphery of the rocket nozzle 2 at axially symmetric positions at intervals of 90 deg. and deflect the jet of combustion gas about orthogonal two axes perpendicular to a body axis and about the body axis under the control of a single member or in cooperation with a plurality of members. The protruding part 3 has four control vanes 5 outside and drive mechanisms 6 inside by which the thrust deflectors 4 interlock with the control vanes 5. Each thrust deflector 4 comprises two deflecting plates 4a which are divided into both sides relative to the axis and respectively rotatable at the same time or one of which can rotate.

    • PURPOSE:To ensure and stabilize the wiper blade motion exclusively by the rotary motion, which allows rise-up motion to shift the blade to a position, where the driver's vision is not obstructed, when the wiper is turned off. CONSTITUTION:One end of a motor arm 61 is fixed to a motor shaft 2, while on the other end, a link shaft 14 is mounted. To the link shaft 14, a primary cam 19 and a secondary cam 20 are closely fitted together in a layer letting a groove 19a and a projection 20a fit loosely. The shaft 14 is also fitted with an eccentric plate 23 and an eccentric metal 71, which revolve jointly with a retainer 27, fitted with a connecting rod 15. Between the metal 71 and the retainer 27, a friction spring 25 is mounted, which enables the metal 71 and the retainer 27 to revolve relatively only immediately after the start and immediately before the encasement and stop of the wiper blade motion.
    • 目的:为了确保和稳定雨刮器的运动,专门通过旋转运动,这允许上升运动将刮刀移动到驾驶员的视力不被阻挡的位置,当刮水器关闭时。 构成:马达臂61的一端固定在马达轴2上,另一端安装有连杆轴14。 在连杆轴14上,主凸轮19和副凸轮20紧密配合在一起,使得凹槽19a和凸起20a松动配合。 轴14还配有偏心板23和偏心金属71,该偏心板与联接杆25的保持器27共同旋转。在金属71与保持器27之间安装有摩擦弹簧25, 金属71和保持器27相对仅在启动之后并且紧接着擦拭器刮片运动的包围和停止之前立即旋转。
