The invention has for its object to provide a heat-shrinkable laminated film for deep drawing, which has an increased carbon dioxide transmission rate (CO2TR) and an enhanced ratio (CO2TR/O2TR) of carbon dioxide transmission rate-to-oxygen transmission rate (O2TR), and is less susceptible to pinholes. In the inventive heat-shrinkable laminated film for deep drawing, a polyamide resin composition layer (a) containing a polyamide resin mixture comprising 60 to 95% by mass of an aliphatic polyamide resin (A) and 5 to 40% by mass of a polyamide base resin (B) having a heat of crystalline fusion of 5 to 40 J/g is laminated onto a heat-sealing resin layer (a) containing a polyolefin resin via an adhesive resin layer (b).

摘要:
To achieve stable, high capacity, high speed recording. Of two light beams emitted from a light irradiation means, one or two beams are made pass through an optical path changeable member whereof at least one of the thickness and refractive index changes continuously or in two or more steps immediately after emission from the light irradiation means, so that a difference is introduced into the optical path length of the two beams, and the focusing point of one beam is made to vary to coincide with a position in the recording layer used for playback or recording. Another light beam is used for servo. Converging of light during recording or read of a multilayer recording medium is performed with higher precision than in the prior art, so higher density, higher capacity recording/playback can be performed.

An inner surface of a cell 12 of a honeycomb carrier 11 except a downstream end of the inner surface in the exhaust direction is coated with a HC (hydrocarbon) adsorption material 13. The inner surface of the cell 12 coated with the HC adsorption material 13 is coated with a three way catalytic converter layer 14. A portion X located upstream side of the exhaust flow and having the three way catalytic converter layer 14 on the HC adsorption material 13, and a three way catalytic converter layer portion Y located downstream side of the exhaust flow are formed on an inner surface of the cell 12 of the honeycomb carrier 11. With this feature, the HC repeats elimination, re-adsorption, elimination, re-adsorption, . . . from the portion of the HC adsorption catalyst 10 upstream of the exhaust flow, finally reaches the downstream end of the portion X including the three way catalytic converter layer 14 on the HC adsorption material 13. Since the downstream end of this portion X is provided with the three way catalytic converter layer portion Y, the HC is converted by the three way catalytic converter layer 14 of this portion Y.
摘要:
An idling control system for a two-plug type internal combustion engine is comprised of an idling detector, an engine rotation speed detector and a controller coupled to the detectors. The controller decides whether the engine rotation speed in idling is smaller than an idling speed by a predetermined value. When this decision is affirmative, the controller differentiates ignition timings of the two spark plugs of each cylinder. This arrangement enables the engine with this system to perform preferable idling performances of generating a torque in response to the input of the external torque and of continuing the combustion against the drop of the engine rotation speed.
