Abstract:
A warp tension control apparatus includes a tension detector for detecting the tension of a warp and an operation mode controller for generating a control signal to drive a motor so as to minimize the deviation between the detected tension and a normal target tension. A long period stop mode controller is included for controlling the tension so that a target slack tension is set to be less than the normal target tension when a loom stop signal has been issued. A selector switch is provided for selectively switching to a contact connected to an output of the long period stop mode controller before entering a long unmanned operating period of the loom, the switch being disposed in a circuit between an input terminal of the long period stop mode controller which receives a loom stop signal and a warp tension slack device. A switch is provided for stopping the output of the operation mode controller when the long period stop mode controller outputs the slack tension control signal such that the warp tension when the loom is stopped is said to be less than that at the time of normal operation only when the selector switch is selectively switched to a contact connected to the output of the long period stop mode controller.
Abstract:
An oscillationless semisubmerged high-speed vessel comprises at least one lower hull submerged below the water surface in the cruising state of the vessel, an upper hull above the water surface and struts connecting the lower hull and an upper hull. The lower hull possesses horizontal fins controlling longitudinal and transverse oscillations of the vessel, steering devices, water ballast tanks for adjusting water line of the vessel and propelling means. The struts are so designed that the water plane area is small so as to minimize the oscillation force, i.e. the vessel does not have a self-stabilizing ability both longitudinally and transversely with only reverse buoyancy kept by the struts when the vessel heels. The struts are constructed to have a sufficient strength for connection of the lower hull and an upper hill. The bulged structures are constructed to contain the propelling means. The struts and the bulged structures are disposed in a midship part of the lower hull to minimize longitudinal oscillations of the vessel due to the wave heaving forces which are vertical components of wave exciting forces generated at both fore and aft parts of the vessel. Steering devices are disposed at a fore part of the lower hull to prevent the vessel from transverse oscillations at an initial stage of healing. Therefore the vessel of this invention can eliminate the oscillations longitudinally and transversely. Thus the vessel of this invention can be an oscillationless high speed vessel which navigates for a long time without causing large accelerative oscillations due to waves on the sea surface.
Abstract:
A lens-fitted photographic film package comprising a light-tight film casing having an exposure opening, a rolled film disposed on one side of the exposure opening in the light-tight casing, a removable light-tight container having a film winding spool therein disposed on the other side of the exposure opening in the light-tight film casing, and an externally operable film winding member for winding the rolled film around said film winding spool of the light-tight film container. The lens-fitted photographic film package is assembled by the steps of winding film withdrawn from a light-tight film container in a roll in a darkroom; loading the rolled film and the light-tight film container in separate respective receiving chambers formed in a main body section of the lens-fitted photographic film package; and fixing a back cover section to the main body section so as to assemble light-tightly the lens-fitted photographic film package.
Abstract:
A thermoplastic elastomer composition and process comprising a crystalline polyolefin, halogenated butyl rubber, olefin copolymer rubber, polyolefin modified with, e.g., maleic anhydride, and, optionally nitrile rubber, wherein the halogenated butyl rubber is at least partially crosslinked using a metal oxide and/or chloride, e.g., zinc oxide. Crosslinking is achieved under dynamic mixing conditions and the resulting composition has superior strength, performance and processing properties. Furthermore, use of nitrile rubber imparts improved oil resistance to the composition.
Abstract:
A synthetic oil having excellent oxidation stability, comprising a mixture of monoalkylnaphthalenes which have each a secondary alkyl group of 6 to 24 carbon atoms and in which the specific molar ratio of .alpha.- to .beta.-substituted monalkylnaphthalenes is at least 1.0. The synthetic oil is useful as a thermal medium oil or as the main component of a synthetic lubricating oil.
Abstract:
A corrosion-resistant pipe coupling made of carbon steel has on its inner surface an intermediate annular projection directed radially inward. At least an innermost part of the annular projection is formed or corrosion-resistant material such as stainless steel. The annular projection is covered by a corrosion-resistant annular member or which is secured by friction welding, electron beam welding, an adhesive or mechanical engagement. The annular member prevents corrosion of the coupling by corrosive fluids flowing in pipes.
Abstract:
A system for controlling and synchronizing the operation of a conveyor system and an article supply system. An encoder monitors the operation of a standard reference or dispensing device along with a rate detecting device. This information is fed into a computer employing a microprocessor. The microprocessor provides an output to a drive system for a conveyor or the like to be synchronized with a supplying or dispensing system.
Abstract:
A double-wall composite pipe is produced by inserting an inner pipe in an outer pipe, filling the inner pipe with cold water under pressure to cause the inner pipe to expand plastically into tight contact with the outer pipe, applying heat to the outer part of the outer pipe by high-frequency induction heating, thereby to establish a locally heated zone thereof around the circumference thereof and causing the heated zone to travel from one end to the other end of the outer pipe thereby to cause it to successively expand locally in diameter in the travelling heated zone. The pressure in the inner pipe then is removed, the pipes thereafter being permitted to attain the ambient temperature, thereby to obtain an interference fit therebetween.
Abstract:
An arithmetic processing unit includes a cache memory, a register configured to hold data used for arithmetic processing, a correcting controller configured to detect an error in data retrieved from the register, a cache controller configured to access a cache area of a memory space via the cache memory or a noncache area of the memory space without using the cache memory in response to an instruction executing request for executing a requested instruction, and notify a report indicating that the requested instruction is a memory access instruction for accessing the noncache area, and an instruction executing controller configured to delay execution of other instructions subjected to error detection by the correcting controller while the cache controller executes the memory access instruction for accessing the noncache area when the instruction executing controller receives the notified report.
