    • A boot seal for variable compression-rate engine includes a boot-seal element, and a reinforcement member. The boot-seal element includes an inner layer, and an outer layer. The inner layer is disposed on the inner face of the boot-seal element, and is composed of a fluorinated rubber. The outer layer is disposed on a more outer side of the boot-seal element than is the inner layer. Moreover, the boot-seal element is formed in a circumferentially developed state so as to have circumferential ends, and is then completed by joining the circumferential ends with each other. Thus, the boot-seal element makes an elastically deformable cylindrical bellows shape having a root that dents inward diametrically. In addition, the reinforcement member is disposed in the root of the cylindrical bellows-shaped boot-seal element at least.
    • 用于可变压缩率发动机的靴形密封件包括靴形密封元件和加强构件。 靴密封元件包括内层和外层。 内层设置在靴密封元件的内表面上,由氟化橡胶构成。 外层设置在靴密封元件的比内层更外侧。 此外,靴密封元件形成为周向展开状态以具有圆周端,然后通过将周向端部彼此接合而完成。 因此,靴形密封元件形成具有沿径向向内凹入的根部的可弹性变形的圆柱形波纹管形状。 此外,加强构件至少设置在圆筒形波纹状靴套密封元件的根部中。

    • A hose connecting assembly of the present invention ensures a tight seal even when a hose 30 is bent and laid out in a narrow space and repeatedly is subject to vibrations under a low-temperature condition. The hose connecting assembly includes a connection tube 10, which is pressed into the hose 30. The hose 30 is designed to have an inner diameter change rate Dc of no greater than 23% under application of an inner pressure of about 0.49 MPa. Ring-shaped projections 21, 22, and 23 are formed on the outer circumferential surface of the connection tube 10. The ring-shaped projections 21, 22, and 23 are designed to make a diameter expansion rate T, which is defined by an inner diameter d1 of the hose 30 and an outer diameter D2 of the ring-shaped projections 21, 22, and 23, at least 25%. A hollow cylindrical end 18 is further formed on an end portion of the connection tube 10. It is preferable that the hollow cylindrical end 18 has a length of at least about 3 mm.
    • 本发明的软管连接组件即使当软管30在狭窄的空间中被弯曲和铺设并且在低温条件下重复地受到振动时,也能确保紧密的密封。 软管连接组件包括连接管10,其被压入软管30.软管30被设计成在内压为约0.49MPa的情况下具有不大于23%的内径变化率Dc。 环形突起21,22和23形成在连接管10的外圆周表面上。环形突起21,22和23被设计成使直径膨胀率T由内部 软管30的直径d1和环形突起21,22和23的外径D2至少为25%。 在连接管10的端部上还形成有中空的圆柱形端部18.优选的是,中空圆柱形端部18的长度至少约为3mm。

    • Providing video telephone apparatus where the orientation of a picked-up image or a received image can be changed according to the orientation of the image pick-up section or the display, thus allowing transmission or display of a proper image at any time.In video telephone apparatus according to the invention, an image pick-up section outputs the image data on the target object to a transmit image rotating section. The transmit image rotating section performs rotation processing on a picked-up image so that the upper side of an image pick-up section in the vertical direction coincides with the upper side of an image to transmit to the distant party, based on the orientation of the image pick-up section detected by an image pick-up vertical direction detector. A picture signal received from the distant party is demodulated and output to a receive image rotating section. The receive image rotating section performs rotation processing so that the upper side of the receive image is at the upper side of a display in the vertical direction, based on the vertical direction of the image pick-up section of the an image pick-up vertical direction detector, that is, the orientation of the display.
