Abstract: The present invention relates to a rotating mechanism for rotating a container including a pair of freely rotatable rollers (351, 351) and one driving roller (349) which holds a flanged portion of a mouth portion of a container at three portions, a pair of roller support rods (352, 352) which support at one ends the rotatable rollers (351, 351) and which can be bilaterally freely opened and closed for embracing the flanged portion of the mouth portion, a mechanism (363, 366, 367) for bilaterally opening and closing the paired roller support rods (352, 352), and a mechanism (353, 356, 357, 358) for driving the driving roller (349).

Abstract: While carrying and rotating a tubular body to be inspected, an image pick up device is inserted into the tubular body to be inspected to pick up an image of the internal surface thereof to take out a corresponding video signal to transmit the video signal to an image processing device through an antenna device to carry out image processing to judge the internal surface of the tubular body to be inspected. In the antenna device ring-shaped conductors are oppositely arranged in a ring-shaped hollow chamber provided within an electromagnetic shielding body wherein one ring-shaped conductor is rotated and the other is fixed.

Abstract: The invention relates to a container conveyor for conveying a container to a container inspecting station. The container has a flanged portion surrounding its opening. The conveyor includes a rotary disc having a plurality of holders arranged around its circumference for holding the containers. The holders include a driving roller and a pair of rotation rollers. The rollers contact the container to provide a three-point connection with the flanged portion of the container. Each roller has a recessed portion formed about its periphery. The recessed portions engage the flanged portion of the container to nip the container.

Abstract: An ink-jet recording head, in which two piezoelectric substrates are opposite each other in polarization direction, and grooves are formed across the interface of the two substrates at a predetermined pitch so as to form cavities. One of each of the cavities is opened to the atmosphere and include an orifice adapted for squirting ink drops. The cavities have electrodes formed on their inner surfaces. When a voltage of one polarity is applied to the electrode for the cavity from which ink drops is to be generated whereas a voltage of the other polarity is applied to the electrodes for the two adjacent cavities, the diaphragms separating the three cavities deform in a shear mode towards the cavity from which ink drops is to be generated. As a result, the capacity of the cavity from which ink drops is to be generated decreases to have the ink in the cavity squirt outward from the orifice.

Abstract: In a nozzleless ink jet printer, a plate-shaped propagation element for propagating a surface acoustic wave is fixedly mounted on a substrate which is arranged along the platen and has an ink pooling groove, and the ink led to the edge of the propagation element from the ink pooling groove by surface tension is caused to jet in the form of ink mist by surface acoustic waves generated by excitation of comb-shaped interleaved electrodes so as to record images such as characters and patterns on a recording sheet.

Abstract: This invention relates to an inspection system for a container made of synthetic resin, including a first container conveying station provided with a plurality of container holders arranged around the circumference of a rotary disc with predetermined spaces; a container feeding station for feeding the containers to a container conveying passage of the first container conveying station with the interval equal to that between the adjacent holders; a first inspecting station for inspecting the existence of the heat resistant resin of the container; a second inspecting station for inspecting the wall thickness of the container; a second container conveying station provided with a container receiving end portion for receiving the container determined to be a good product by the inspections of the first and second inspecting stations and conveying the container externally of the first container conveying station; and a first container discharging station for discharging a container judged to be a faulty product by

Abstract: This invention relates to an inspection system for a container made of synthetic resin, comprising: a wall thickness inspecting apparatus having a projector for emitting an inspection light guided from a light source inserted into a container made of synthetic resin and provided with one end opened towards the wall of the container, a light receiver arranged in opposition to the projector at an external portion of the container for receiving the inspection light passing through the wall of the container and converting the received light into an electric signal, and an arithmetic operation device for calculating the wall thickness of the container on the basis of the output signal from the light receiver; a first container conveying station provided with a plurality of container holders arranged around the circumference of a rotary disc with predetermined spaces; a container feeding station for feeding the containers to a container conveying passage of the first container conveying station with the interval eq

Abstract: A long sheet material to be sterilized is passed through an atmosphere of H.sub.2 O.sub.2 mist of low concentration and of droplet particle size of approximately 10 microns at room temperature for approximately one second and is then irradiated for approximately one second with ultraviolet-ray lamps positioned to irradiate opposite surfaces of the sheet material each at a distance of approximately 20 mm therefrom, whereby the material is thoroughly sterilized as a result of the synergistic effect produced by the combination of these two sterilization steps.

Abstract: Apparatus particularly suitable for sterilization of a succession of food containers being fed intermittently along a horizontal path, preparatory to the filling of such containers with a desired food. Formed over and under the feed path are two opposed sterilizing chambers into which a sterilizing solution is supplied in subdivided form for application to the successive containers. In some embodiments the sterilizing chambers are provided with spray nozzles for spraying the sterilizing solution onto the containers, while in others the sterilizing solution is ultrasonically atomized into fine mist in a separate atomizing section, the mist being then directed into the sterilizing chambers. The apparatus further includes heaters for heating the sterilizing chambers and other pertinent parts in order to afford subdivision of the sterilizing solution into fine, uniform droplets and to prevent their condensation into large drops.
