Abstract: This image sensor includes a flexible wiring board connected with an optical sensor, bent around the portion connected with the optical sensor and so formed as to generate urging force oppositely to the bent direction and a support portion having a first support surface supporting the optical sensor. The optical sensor is urged toward the first support surface of the support portion to be fixed thereto due to the urging force of the flexible wiring board arranged in the bent manner.

Abstract: In this image sensor, a first spring member is so arranged that the urging direction of the first spring member is inclined with respect to the axis of a first rotating shaft of a first driving source thereby inclining a transmission member urged by the first spring member with respect to the axis of the first rotating shaft and bringing the transmission member into contact with a first pressing member engaging with the first rotating shaft, so that the first pressing member engages with the first rotating shaft while the axis of the first pressing member is inclined with respect to the axis of the first rotating shaft.

Abstract: Disclosed is a sterilizing and vacuum packaging bag having at least one non-fused degassing portion, wherein an insufficiently fused area is present inside the degassing portion. The insufficiently fused area is lower in fusion strength than the vertical fused areas and a bag mouth fused area, and is fused so as to be separable by an increase in inner pressure. Further disclosed is a vacuum packaging method comprising using this sterilizing and vacuum packaging bag, including putting contents into the bag through an open end thereof, fusing the open end more firmly than the insufficiently fused area, performing microwave heating, separating films fused together at the insufficiently fused area at a stage that the surface temperature of the contents is also sufficiently elevated, and completely fusing the degassing portion after termination of microwave heating.

Abstract: A laminate film for forming a tightly sealed bag that can be opened easily by tearing at an edge thereof. The film is a laminate of a substrate layer and a heat seal layer, the substrate layer having a multiplicity of through cuts formed therein, said through cuts being partially or wholly filled by the heat seal layer material.

Abstract: A container (10, 10A) for a long object (50) has an opening (18) which is formed in the container wall (12) at a position adjacent to an open end edge (14) of the container and which allows the long object to be extracted therethrough. A first notch (22) is formed in the open end edge spaced from the opening (18) so as to extend in the direction of length of the container. The first notch is capable of receiving a portion of the long object extracted through the opening. A second notch (3) spaced apart from the first notch is formed in the open end edge of the container so as to extend in the direction of the length of the container. The second notch (30) is provided with a cutter (40) in the bottom thereof. The arrangement is such that the portion of the long object which has been extracted past the first notch is forced into the second notch so as to be cut by the cutter.

Abstract: A process for producing a tightly sealed bag that can be easily opened by tearing at an edge thereof. According to the process a multiplicity of through cuts are formed along a line in a laminate film having at least one substrate layer and at least one heat seal layer. The laminate film is formed into an open bag with the line of through cuts provided along an edge to be sealed of the bag and edges of the open bag are heat sealed to form a sealed bag. In an alternative embodiment of the process, a multiplicity of through cuts are formed along a line in a substrate film and a heat seal film is laminated to the substrate film provided with the through cuts to form a laminate film prior to forming the sealed bag.

Abstract: A device for forming slits, or through cuts, in a plastic film. The device is a disc having a circumferential surface and pseudotriangular slender cutting edges consisting of protrusions aligned linearly in a plurality of straight rows extending around the entire circumferential surface, the protrusions extending outwardly from said circumferential surface at angle of at least 60.degree. and no greater than 100.degree..

Abstract: This invention provides an easily openable tightly sealed plastic bag which is formed of a film containing at least a substrate layer and a heat seal layer and is possessed of a sealed part whose substrate layer contains a multiplicity of through cuts, these cuts being formed substantially on the edge lines and partly or wholly closed with the heat seal layer. This tightly sealed bag safely retains the practical strength normally expected of any bag and avoids accidentally sustaining rupture while the bag is being transported or handled and yet permits itself to be opened with the force of finger tips. This invention manifests its utility particularly in a tightly sealed bag which is formed of a substrate of high strength and high barrier property. This invention further provides a method suitable for the production of the tightly sealed bag described above and a device to be used in working the method.

Abstract: A cutter has a file-like coarse surface formed on a substrate by fast adhesion of irregular granules to the surface of the substrate with a soft adhesive agent. A dispensing container has the cutter attached fast thereto. The cutter can be folded and attached fast to a ridge of a dispensing container, the ridge in a position such that a sheet material drawn out of the dispensing container will be pressed most readily, without sustaining a crack in the layer of adhesive agent and inducing unwanted separation of irregular granules from the substrate.

Abstract: A plastic film product, such as a sealed bag, wound film or adhesive tape, has a plurality of random scratches or cuts having notches toward the other side of the film, formed along the edges thereof so as to be shallow and small enough to be invisible to the naked eye in order to reduce resistance to tearing perpendicular to the edges.

Abstract: A cutting device using as its cutting edge a coarse file-like face, a method for cutting a thin sheet or film by causing at least the cut-starting portion of the thin sheet or film to be pressed against the coarse file-like face of the cutting device, and a dispenser for a thin sheet or film provided with the aforementioned cutting device using said coarse file-like face as a cutting edge thereof are disclosed. A thin sheet or film is readily torn when a notch or cut is formed at the cut-starting portion of the sheet or film. The present invention makes use of this property of the thin sheet or film.

Abstract: A vacuum-suction typed holder for flexible tube-shaped film materials made from plastics wherein the tube-shaped film materials whose upper end open and the bottom is sealed are fed thereinto and they are rendered to expand by suction applied from the periphery thereof, in order to facilitate to put, for example, sausage therein.
