Abstract: A method of and device for improving the quality of fresh concrete and preventing adhesion and hardening of the mixed fresh concrete in a rotary mixer drum of a concrete mixer truck or a stationary mixer drum of a concrete mixer plant which involves delivering selectively and continuously either cold or warm air into the mixed fresh concrete in the rotary or stationary concrete mixer drum in order to delay the hardening time of the mixed fresh concrete, and to avoid adhesion and hardening of the mixed fresh concrete on a plurality of blades and an inner periphery of the mixer drum.

Abstract: A manufacturing method for a photo-sensitive film magazine packed in a container is disclosed. The method comprises the steps of (a) assembling a photosensitive film magazine in a photosensitive film magazine assembly section (b) feeding successively the photosensitive film magazine to a container accommodation section from said photosensitive film magazine assembly section through a predetermined passage and (c) setting the photosensitive film magazine into a photosensitive film magazine container in the container accommodation section.

Abstract: Disclosed herein is a coaxial feeding-type plasma processing chamber or an opposed electrode-type plasma processing chamber using an Etch-tunnel comprising: a cylindrical treatment chamber having a gas-introducing mechanism and a gas-exhausting mechanism, and equipped with a heating mechanism at the periphery thereof; an external electrode disposed in close contact to the outer periphery of the cylindrical treatment chamber; and a metal cylindrical member disposed coaxially at a predetermined gap to the inner wall of the cylindrical treatment chamber and a having a plurality of small apertures in the side wall thereof,the gas-introducing mechanism being composed of a gas-introducing pipe having a plurality of gas-blowout means and disposed along the longitudinal direction of the cylindrical treatment chamber, and a gas reservoir connected by way of a pipeline; the gas-exhausting mechanism being composed of a gas-exhausting pipe having a plurality of gas-suction apertures and disposed along the longitudinal di

Abstract: An automatically controlled film packaging system which is capable of exposing necessary data as a latent image onto the edges of pre-used film according to the input signal of a unit length required for the merchandise cutting the film into the unit length and taking the film up on a selected patrone, comprising a center processing unit which controls the system automatically when the unit length required is shifted, without any manual re-setting but only by inputting a new unit length of the film required for the merchandise to be produced.

Abstract: A method of reading a bar code printed on a photographic film cartridge in which the bar code has a certain arc length on the cartridge. The cartridge is transported on a conveyor and positioned on the conveyer so that the normal line intersecting at the middle point of the arc length forms an acute angle to the transporting direction of the conveyer. The bar code is irradiated with a light beam of a bar code reader while the cartridge is transported on a conveyer, and the irradiating angle with the transporting direction is determined smaller than the acute angle of the normal line intersecting the bar code.

Abstract: A film winding apparatus comprises a positioning device for a spool of a photographic film having a lateral rib formed on the external circumference of the core of the spool, around which a photographic film with a predetermined length is wound, and this apparatus consists of a driving shaft with a chuck to hold the spool, a stopping device with which the rib comes into contact to stop the rotation of the spool, a one way clutch attached to the driving shaft to prevent the shaft from rotation, and a motor for controlling a driving device connected with the driving shaft and a drive device for controlling the stopping device to stop the rotation of the spool at a predetermined position.

Abstract: An apparatus for conveying a tape material having different surface moduli on either side by nipping with a pair of rotatable rollers and a method of conveying the same is disclosed. The tape material having different surface moduli is conveyed by an apparatus having a pair of rollers having different surface moduli with each other, so that the roller in contact with the relatively higher elastic modulus side of said tape has a relatively higher surface elastic modulus, and the roller in contact with the relatively lower elastic modulus side of the tape has a relatively lower surface elastic modulus.

Abstract: A process for the continuous preparation of slides to be chemically analyzed comprises forming regularly a plurality of hollows on an advancing web material; putting a piece of film to be chemically analyzed in each of the hollows; sticking a long covering member having a plurality of apertures corresponding in their positions to the hollows on the web material onto the surface of the web material so that the apertures and the hollows on the web material are in registration; and cutting the circumference outside of each of the hollows. Also disclosed is a slide to be chemically analyzed which comprises a web material having a hollow in the central region thereof in which a film to be chemically analyzed is put, a covering member having an aperture on the surface thereof stuck to the web material; and downwardly extending flanges on a circumferential portion of the slide having heights substantially equal to that of the hollow to stabilize positioning of the slide.
