Abstract: Provided is a portable bidet capable of maintaining the quality of cleaning water. A portable bidet is configured to include a tank portion formed to be compression-deformable and restorable to its original shape, a nozzle that is connected to the tank portion and can discharge a fluid, and a sealing portion that is provided continuously to the nozzle. The tank portion and the nozzle are connected via a cylindrical portion having a cylindrical shape. In a sealed state where the fluid is sealed by the sealing portion, the fluid is fully filled in a storing chamber in a state where the tank portion is compressed, and in an opened state where sealing by the sealing portion is released, the tank portion is restored to its original shape, and a volume of the storing chamber is expanded as compared with a volume of the storing chamber in the sealed state.

Abstract: A regeneration process in the operating method of the invention includes a first regeneration process, and a second regeneration process after the end of the first regeneration process. In the first regeneration process, a regenerant is distributed at a top of an ion exchange resin bed and simultaneously the regenerant is collected at a bottom of the resin bed, thereby generating a downward flow of the regenerant to regenerate the whole of the resin bed. In the second regeneration process, the regenerant is distributed at a bottom of the ion exchange resin bed and simultaneously the regenerant is collected at a middle of the resin bed, thereby generating an upward flow of the regenerant to regenerate a part of the resin bed.

Abstract: A regeneration process in the operating method of the invention includes a first regeneration process, and a second regeneration process after the end of the first regeneration process. In the first regeneration process, a regenerant (5) is distributed at a top (8) of an ion exchange resin bed (2) and simultaneously the regenerant (5) is collected at a bottom (9) of the resin bed (2), thereby generating a downward flow of the regenerant (5) to regenerate the whole of the resin bed (2). In the second regeneration process, the regenerant (5) is distributed at a bottom (10) of the ion exchange resin bed (2) and simultaneously the regenerant (5) is collected at a middle (11) of the resin bed (2), thereby generating an upward flow of the regenerant (5) to regenerate a part of the resin bed (2).

Abstract: A boot for a universal shaft coupling, by which an improvement of an assembling workability can be expected, and an improvement of a sealing performance can be expected. The boot for the universal shaft coupling is formed by a rubber elastic body, and separated portions (22) are formed linearly along a generatrix. A fastener pair (26) is arranged in both sides of the separated portions (22) so as to form a seal portion. The fastener pair (26) is constituted by an occluding portion (32) formed in one end edge of the separated portion (22) and provided with a bulge locking portion (32a) in a leading end, and an occluded portion (34) formed in another end edge of the separated portion (22) and provided with an occluding groove (33) occluding with the bulge locking portion (32a).

Abstract: Ion exchange equipment which can deal with counter-flow regeneration or split-flow regeneration while simplifying a water collector. The ion exchange equipment comprises a first water collection pipe (14) communicating with a first channel (10) formed in a lid member (7) at a resin containing section (2), and second water collection pipe (20) communicating with a second channel (11) formed in the lid member (7), wherein an inner diameter of the second water collection pipe (20) is set larger than an outer diameter of the first water collection pipe (14). The water collection pipes (14, 20) have axes set coaxially with the axis of the resin containing section (2) and form a double pipe, and a third channel (12) communicating with the resin containing section (2) is formed in the lid member (7).

Abstract: A diesel engine intake system including a timing valve which is positioned in the intake system in engine starting and warming-up period under a cold engine condition. The timing valve is opened in the final period of the intake stroke so that a strong suction pressure is produced in the combustion chamber before the timing valve is opened. When the timing valve is opened, the intake air is rushed into the combustion chamber at a high speed whereby the intake air is compressed under the inertia of the high speed flow to thereby increase the temperature of the intake air. The timing valve is responsive to the suction pressure in the combustion chamber and opened when the suction pressure becomes stronger than a predetermined level.

Abstract: The fuel injection system for a diesel engine comprises a pintle type fuel injection nozzle having a valve needle slidable back and forth in the axial direction thereof between a first position in which its front end portion is inserted in a spray hole and a second position in which its front end portion is retracted from the spray hole, fuel supply means for feeding pressurized fuel to the fuel injection nozzle, and a plunger member which is slidable in the axial direction of the valve needle and provided with a front end face opposed to the rear end face of the valve needle and a rear end face adapted to receive the pressure of the pressurized fuel fed to the fuel injection nozzle from the fuel supply means, the valve needle being adapted to be lifted by a predetermined fuel pressure to a pre-lift position where the rear end face of the valve needle abuts against the front end face of the plunger member so that further lift of the valve needle is suppressed by the fuel pressure acting on the rear end face o
