Abstract: In a urine sampling container 1, a retaining mechanism 15 is provided on opening end sides of a urine collection tube 3 and a cover tube 4 to prevent the cover tube 4 from being removed from the urine collection tube 3 in a state in which the urine collection tube 3 is inserted to and fitted in the cover tube 4, so as to keep the urine collection tube 3 and a storage tube 2 securely coupled with each other at the time of urine collection and to allow the storage tube 2 to be easily removed from the urine collection tube 3 at the time of examination.

Abstract: A method for obtaining high-purity phosphorus pentafluoride (PF5), which is industrially useful in the fields of semiconductors and batteries, from PF5 containing a gas mixture of HCl, HF, and so on. Specifically, provided is a process for purifying phosphorus pentafluoride including (1) an immobilization step in which phosphorus pentafluoride containing a mixture is brought into contact with a metal fluoride (MFn; M is an n-valent metal) having a specific surface area of 1.0 m2/g or more at 40° to 150° C. to immobilize phosphorus pentafluoride in the form of a hexafluorophosphate (M(PF6)n), (2) a separation step in which the mixture remaining in the gas phase is expelled out of the reaction system to separate the mixture from the hexafluorophosphate, and (3) a heat-decomposition step in which the hexafluorophosphate freed of the mixture is heated at 150° to 400° C. under a pressure of ?0.1 to 0.1 MPa·G to give phosphorus pentafluoride.

Abstract: A urine collection vessel includes: a narrow cylindrical container tube (2) for containing urine provided with an end closed and the other end opened; a narrow cylindrical urine collection tube (3) for collecting urine provided with an end closed, the other end which is opened and freely connected or disconnected to the opened end of the container tube (2) and a urine collection inlet (33) provided at the side of the urine collection tube; and a narrow cylindrical cover tube for closing the urine collection inlet (33) provided with an end closed and the other end opened and has a slightly larger diameter than the diameter of the urine collection tube (3) such that the urine collection tube (3) is freely inserted into and removed from the cover tube. Part of the urine collection tube (3) ranging from the urine collection inlet (33) to the closed end is formed as a measuring part (31) which contains and measures a predetermined amount of urine.

Abstract: A nozzle 33 is formed on a distal end side of a cylinder 3. The nozzle 33 has an intermediate portion 3b formed such that a tip 7 is freely attachable thereto and detachable therefrom. The intermediate portion 3b of the nozzle 33 is formed with an annular projection 3e for retaining the tip 7. The tip 7 has a thick portion 7a provided in a root portion thereof and formed larger in diameter than a root portion 3a of the nozzle 33 to be abuttable against a tip releasing member 11. Along an inner periphery of the root portion of the tip 7, an annular projection 7b is formed to contact with the annular projection 3e of the nozzle 33 thereby providing a seal with the nozzle 33. Both the annular projections 3e and 7b of the nozzle 33 and the tip 7 are arranged to reach a position where a sound of abutment is produced between the root end surface of the tip 7 and the shoulder of the nozzle 33 at the completion of fitting of the tip 7 onto the nozzle 33.

Abstract: A cylindrical vessel body 20 has an end opened. A urine taking cap 50 comprises a fitting cylinder section 51 which can be freely fitted in tight contact with the opened end of the vessel body 20, a urine sampling cylinder section 52 connected to the fitting cylinder section 51 and having a urine sampling inlet 5b opened thereon, and a grip section 53 connected to an outer end of the urine sampling cylinder section 52. In addition, a cover cylinder 30 has an end opened, the opened end being capable of being fitted in tight contact with a tapered face 5e of the urine sampling cylinder section 52 in the state in which the vessel body 20 having the urine taking cap 50 attached thereto is inserted. A ring protrusion 55 is formed on an outer peripheral face of a connecting portion of the urine sampling cylinder section 52 and the grip section 53, and the grip section 53 can be freely extended axially by an extension cylinder 5g.

Abstract: An apparatus for presetting the photographing distance for a camera is responsive to a movement of flash photography operating means to operate switch operating means which is disposed within an electronic flash to turn a power switch of the electronic flash on. In addition, means for adjusting photographing distance is also operated to bring a taking lens to a flash photography position which is located on the nearer side than a normally focussed position, in an automatic manner.

Abstract: An apparatus for establishing a routine shot distance of taking lens for camera which includes a lens protective cover is provided. The cover is movable between a first position in which it covers a taking lens and a second position in which it allows the taking lens to be exposed. An arrangement is provided for moving the taking lens to a position corresponding to a selected routine shot distance in response to the opening/closing movement of the lens protective cover. The position corresponding to a selected routine shot distance can be freely chosen.

Abstract: An electrical contact material consisting essentially of silver and a small amount of zinc oxide, tellurium oxide, and optionally indium oxide and tin oxide, these oxides being uniformly dispersed in the silver matrix.
