Abstract: An environmental test apparatus comprising a substrate on which a test specimen is mounted securely, a cover disposed on the substrate for housing the test specimen within a tightly closed space thereof, a temperature/moisture adjusting system for adjusting temperature and moisture in the tightly closed space, a memory for storing control data such as accumulated past data or various kinds of environment reproduing data, a control system for controlling the temperature/moisture adjusting system based on the control data stored in the memory and a data measuring system for measuring and recording various kind of data for environmental test.

Abstract: A continuous filtration device comprising a cylindrical filter rotationally driven around the axis thereof, a filtration tank in which an outer chamber having an inlet for a liquid to be cleaned and an inner chamber having an exit for a liquid filtrate are separated by the filter, a cleaning means disposed in the outer chamber for spraying a cleaning liquid at high pressure at an acute angle to a surface of a filter to be cleaned, and a guide plate disposed at a position on the side opposite to the cleaning means with respect to the surface to be cleaned for guiding obstacles removed by cleaning and detaching them from the filter. The filter can be automatically cleaned by spraying a liquid to be filtered, liquid filtrate or similar other liquid to the surface of the contaminated filter. The device is useful, for example, for filtration of marine fuel oils or lubricants.

Abstract: A self-propelled fork lift truck comprises a working mechanism at the front end of the fork left truck, a revolving driver's stand, a driver's seat and a steering wheel mounted on the revolving driver's stand, a speed change gear having a plurality of speed shifting ratios for running in a forward direction and a plurality of speed shifting ratios for running in a backward direction, and a speed change gear controlling device. When the revolving driver's stand is turned facing the front end of the fork lift truck, the controlling device restricts the operation of the speed change gear to a first of the plurality of speed shifting ratios for running in the backward direction. When the revolving driver's stand is turned facing the rear end of the fork lift truck, the controlling device restricts the operation of the speed change gear to a first of the plurality of speed shifting ratios for running in the forward direction.

Abstract: A transportation container comprises a container main body for loading two lower stage cars on a floor surface, a front deck supported on both side walls of the container main body for loading and holding one upper stage car while displacing it in the longitudinal direction relative to both of the two lower stage cars, at least a portion of the loading face for the one upper stage car being situated below the top end of the lower stage cars, a front deck guide mechanism for loading the one upper stage car by self-running on the front deck, a rear deck supported at least at the front side end thereof to both of the side walls of the container main body for loading and holding another upper stage car while displacing it in the longitudinal direction relative to both of the lower stage cars, at least a portion of the loading face for another upper stage car being situated below the top end of the lower stage cars, a rear deck guide mechanism for loading another upper stage car by self-running to the rear deck, a

Abstract: A bulkhead for use in container liner bags comprises a liner bag mounted to the inside of a container and containing goods charged therein, a plurality of support members disposed while being vertically spaced apart from each other to the end of the container on the side of the door, the both ends of which are detachably fitted to engage into the recessed grooves on both of the side walls of the container for supporting the end face of the liner bag on the side of the door, a positioning apparatus for fixing the vertical position of the uppermost support member and a spacer apparatus for suspending the support members other than the uppermost support member from the just-mentioned uppermost support member for fixing the vertical position between them. The assembly of the support members can serve as an effective bulkhead because of easy attaching and detaching while possessing sufficient withstanding force.

Abstract: The container for use in the transporation of fresh provisions comprises a storage chamber for containing perishable foods and a machine room divided from each other by partition walls, main cold air flow channels opened at one end on the side of a door and auxiliary cold air flow channels closed at the other end on the side of the door, both of which are respectively disposed to the surface of the bottom wall, top wall or one side wall of the storage chamber, apparatus for blowing cold airs having ports perforated substantially over the entire region at the surface of the auxiliary cold air flow channels on the side of the storage chamber, apparatus disposed within the machine room for controlling the temperature of the recycled cold airs from the storage chamber and then supplying them by way of the main cold air flow channels to the inside of the storage chamber, and apparatus disopsed within the machine room for pressurizing the circulated cold airs from the storage chamber and then feeding them by way of

Abstract: The liner bag for use in containers comprises a bag main body having bottom, side, front and upper faces corresponding to the configuration on the inner walls of a container, in which the joining edge between the upper face and the side face is bent convexly toward the opposed joining edge, engaging members for detachably engaging the bag main body near the upper and lower four corners on the front thereof to the container, a pair of engaging metal members attached respectively to the two upper corners on the container door side and a pair of side belts which are attached along the joining edges between the upper face and both of the side faces, the ends of which are led out from the ends of the upper face on the door side and in which the led out portions are clamped with each other after being engaged to the engaging metal members. The liner bag can easily be installed to and removed from the container and the sagging in the upper face of the liner bag can be prevented without reducing the volume thereof.
