Abstract: A container substantially made of plastic materials and having a gas barrier property. The container has a wall including a laminated sheet which comprises an inner layer and an outer layer both made of a thermoplastic material and an intermediate barrier layer between the inner and outer layers and made of a resin material of which gas barrier property can be improved by stretching. The intermediate layer is held between the inner and outer layers in a stretched state. A rigid layer of a large thickness may be provided outside the outer layer. In manufacturing the container, the intermediate layer may be in a stretched state when the laminate is provided. The rate of stretching can be increased when the laminated sheet is formed into the shape of the container.

Abstract: In a card reader for reading information from a card which may contain the information as optical, magnetic, electronic or physical data, inside a casing is provided a carriage which carries the card and is adapted to be conveyed from an outer position to an inner position by a linear drive mechanism. By not using a pair of drive and pinch rollers as opposed to conventional card readers, the card is free from contaimination by the rollers, and the operation reliability of the card reader is improved. Further, the elimination of rollers also contributes to the reduction in the overall height of the card reader. The clamp mechanism for securing a card to the carriage may be provided with interlocking means which prevents the movement of the carriage until a card is securely gripped by the clamp mechanism.

Abstract: A method for thermal transfer printing by heating a transfer sheet having a printing ink layer formed on a base sheet with a hot roll, wherein the base sheet comprises biaxially stretched plastic film, and, at the same time, pressing with the hot roll the transfer sheet against a substrate for printing, thereby transferring the printing ink layer to the substrate, wherein the substrate for printing is preheated prior to the pressing, and a transfer printing machine having a supplying roll axle for a roll of transfer paper urged to rotate in the rewinding direction by an urging force, a heat roll for performing heat transfer by pressing one surface of the transfer paper on which printing ink is not applied so as to cause the transfer paper to pressingly contact an object of transfer with a surface to which printing ink has been applied, and a takeup roll axle adapted for intermittently rotating and rewinding, for each rotation thereof, one pitch of the transfer paper having undergone the transfer, an improveme

Abstract: A paint discharge rate control system includes a paint flow regulator provided in a paint supply line connecting a color changing valve group to a painting nozzle, a paint mass flow meter for measuring the mass flow rate of paint, provided in the paint supply line, and a control for controlling the paint flow regulator on the basis of a paint mass flow rate measured by the paint mass flow meter to control paint discharge rate. The control converts a measured paint mass flow rate measured by the paint mass flow meter into a volumetric flow rate, and controls the paint flow regulator during a push-out operation, in which the valves of the color hanging valve group are closed and a valve for supplying a washing liquid is opened, so that the paint remaining in the paint supply line is pushed out by the washing liquid at a paint discharge rate at which the paint is discharged during the main step of painting.

Abstract: A container lid structure made essentially of plastics. The lid structure includes a lid frame and a lid plate. The lid plate includes an inner layer comprising a metal foil coated at the opposite sides by plastic layers and connected at the peripheral portion with the lid frame and a core made of a material which is not adhesive to or has a weak bonding power with the plastic material for the lid frame and for the plastic layer of the inner layer. The core is laid over the inner layer with the peripheral portion in an abutting relationship with the inner periphery of the lid frame. A holding member is formed on the core and bonded to the inner layer through apertures in the core. A pulling tab is also formed on the core and bonded to the inner layer through an aperture in the core.

Abstract: A process for producing retort boiled rice by charging raw rice and water into a container, adjusting the quantity of oxygen in the head space of the container to from 4-12 ml/100 g of raw rice, sealing the container and then boiling and sterilizing the rice.

Abstract: A plastic can is formed of a body member including a content protecting layer which is a tubular body formed by folding back and outward one side edge of a laminated film, bonding the folded parts such that air bubbles are not entrapped thereunder, overlapping the other side edge of the same laminated film on the bonded surface and bonding the side edges such that air bubbles are not entrapped between the side edges. An additional sheet is bonded all over the external surface of the laminated film except for a projecting stripe formed by the bonding of the side edges. A surfacing plastic layer covers the additional sheet and the projecting stripes. An apparatus is provided for forming the can, smoothing the surfacing plastic layer, forming the tube into can bodies, shaping the can bodies and sealing, lids on the ends of the cans.

Abstract: A transparent plastic can which comprises a transparent body formed of a laminated plastic structure, the inner surface of which is coated with a thin layer of silicon oxide.

Abstract: A body for a pressure-resistant vessel comprising a spirally wound layer formed by a uniaxially stretched film of a crystalline high polymer, e.g., a can. The composite plastic cans according to this invention are useful for holding pressurized carbonated beverages.

Abstract: A tool clamping device for clamping a tool on a main spindle or releasing the same from the main spindle, which includes: a main spindle rotatably supported on a headstock; a push rod extended through the spindle hole of the main spindle so as to be axially slidable, urged rearward by a weak spring and capable of being moved axially for fixing a tool to or releasing the same from the main spindle; a clamping spring for pressing the push rod rearward; a sleeve disposed contiguously with one end of the clamping spring so as to be movable relatively to the push rod; a first interlocking mechanism formed between the push rod and the sleeve so as to interlock the sleeve with the push rod when the sleeve moves in a direction to allow the expansion of the clamping spring and to release the sleeve from the push rod when the sleeve moves in a direction to compress the clamping spring; a second interlocking mechanism capable of being disengaged by the movement of the push rod in a direction to compress the clamping spr
