Filed: 1987-08-10
Abstract: PURPOSE:To make it possible to carry out online coating by means of blow molding, by constituting a core layer with a polyamide resin wherein an inorganic filling material is added and a skin layer with a polyamide resin, a polypropylene resin or an acrylic resin containing no filling material. CONSTITUTION:As a resin A used for a core layer, polyamide resins such as polyamide 6, polyamide 66, polyamide 11, polyamide 12,aromatic polyamides and so on are used. As a filling material added in the resin A, calcium carbonate, talc, glass fibers, silica and so on are used. As a resin B used for a skin layer, beside the polyamides used as the resin A, polypropylene resins and acrylic resins are used. If the thickness of the skin layer is too thin, the appearance of the skin layer is influenced by the roughness of the filling material in the core layer and therefore the thickness is preferably 0.2mm or more. If the thickness is too thick, the rigidity is lowered and therefore it is preferably 1.0mm or less. Further, when 5-40% inorganic filling material are added to the resin A, the coating appearance is remarkably improved due to formation of the skin layer when multi-layer blow molding is done.

Title: Controller for continuously variable transmission
Inventor: SAWA KENJI
IPC: B60W10/101
Filed: 1986-08-25
Abstract: PURPOSE:To certainly prevent the selection of the torque transmission in a continuously variable transmission in the retreat direction, simplifying the constitution of the captioned device, by constituting the captioned device so that the hydraulic pressure of a pressure adjusting valve is lowered when the erroneous retreat range is selected during the advance traveling. CONSTITUTION:The captioned device is constituted so that the hydraulic pressure adjusted by a pressure adjusting valve is lowered when the erroneous retreat range is selected during the advance traveling. Therefore, a hydraulic clutch 21 is set into the cut-off state, namely to the state for cutting off the transmission of the engine torque to an advance/retreat selecting mechanism 20, and the shift actuator of the advance/retreat selecting mechanism 20 stops the selecting operation. Therefore, the continuously variable transmission does not select the torque transmission to the retreat direction, accompanied with the range selection. Further, the pressure adjusting valve originally adjusts the hydraulic pressure supplied into the hydraulic clutch 21 and is not specially installed, and the constitution of the controller can be made simple.
