Abstract: An electrolytic test machine is used for a corrosion resistance test for a test material comprised of a metal blank and a coating film. The electrolytic test machine is constructed so that an adverse influence, due to chlorine gas generated during a test, can be inhibited. The electrolytic test machine includes an electrolytic cell in which an aqueous solution of NaCl is stored so that a test material is immersed in the aqueous solution of NaCl. An electrode is immersed in the aqueous solution of NaCl. A DC power source supplies electric current between the electrode and the test material. A chlorine gas treating device collects chlorine gas which is generated with electrolysis of the aqueous solution of NaCl and which is released out of the aqueous solution of NaCl along with the aqueous solution of NaCl. The chlorine gas treating device includes a treating pipe line, a suction pump mounted on the treating pipe line, and a chlorine gas purifying member.

Abstract: An electrode is mounted in a vertical manner in an electrolytic liquid in an electrolytic cell. A harmful gas collecting hood is disposed within the electrolytic cell to cover the entire upper portion of the electrode. One end of a bottom surface of the hood lies at a higher location than the other end of the bottom surface of the hood. An inlet of a harmful gas treating pipe line is disposed in the vicinity of that portion of the bottom surface of the hood which lies at the higher location thereof. A harmful gas generated around the electrode is smoothly guided to the inlet by a guide effect of the hood and sucked into the inlet.

Abstract: A sprayer according to the present invention is suitable for a sprayer of type which is mounted to a neck portion of a container and pumps up liquid contained in the container to spray the liquid. The term "spray" includes a meaning of spraying the liquid in the atomized state by making the liquid into fine particles and a meaning of spraying the liquid in the foamed state by further making the fine particles mixed with air. A collision plate 50 is disposed in front of a discharge nozzle 21 so that the spray state when the collision plate 50 is in the closed state and that when the collision plate 50 is in the opened state are different from each other.

Abstract: A magnetic recording medium having a non-magnetic support and provided thereon a magnetic layer containing a ferromagnetic ion oxide and a binder, said ferromagnetic iron oxide containing Si and/or Al at a proportion of 0.10 to 0.25% by weight and methods of manufacturing a magnetic recording medium are disclosed.

Abstract: A stator coil of a generator for vehicles is provided with a stator coil construction and method for winding the stator coil around the core. The coil is wound around the stator core so that a portion of the stator coil projects from one or both sides of the stator core in the axial (longitudinal) direction of the core. The projecting portion of the stator coil closely surrounds the rotor core and is composed of inner and outer wire batches between which are formed slits which permit cooling air to pass therethrough and cool the coil more efficiently. The cooling air is generated by a fan which is attached to the rotor core facing the inner surface of the projecting portion of the stator coil.

Abstract: An alternating current generator includes a frame, a rotation shaft, a slip ring attached to the rotation shaft, a brush in contact with the slip ring, and a brush holder secured to the frame. The brush holder includes a brush-guiding portion and a cover portion. The brush-guiding portion of the brush holder has a hollow slidably receiving the brush for movement in a radial direction with respect to the rotation shaft. The cover portion of the brush holder encloses that portion of the rotation shaft whee the slip ring is attached so that the slip ring is protected from outside dust and splash. This cover portion is integrally formed with the brush-guiding portion in such a manner that neither a clearance nor a mating surface is produced between the cover portion and the brush-guiding portion.

Abstract: An apparatus for swelling and drying foods under reduced pressure in which the apparatus comprises a reduced pressure treating chamber connected to a vacuum pump directly or through a reservoir tank, a drying chamber having a pressure reducing means, a heating means and a conveying means, and an outlet chamber having a pressure reducing means and in which said reduced pressure treating chamber, said drying chamber and said outlet chamber are continuously arranged in this order.

Abstract: A magnetic recording medium having a magnetic layer on one side of a support and a backcoat on the other side containing a non-magnetic powder and a binder resin is disclosed. The non-magnetic powder comprises particles having an average size greater than 0.5 .mu.m and smaller than 2.0 .mu.m and a maximum size of not more than 5 .mu.m.

Abstract: A magnetic recording medium having a magnetic layer and a backing layer on opposite sides of a support is disclosed. The backing layer comprises a binder resin, a conductive carbon black and an organic powder.

Abstract: Disclosed is a magnetic recording medium which comprises a support, a magnetic recording layer and optionally a back-coating layer, at least of said magnetic recording layer and said back-coating layer containing a urethane resin having a yield point.The tape performances of the magnetic recording medium according to the present invention can be markedly improved by incorporating the urethane resin having a yield point.
