Abstract: The invention pertains to the method and apparatus of compensating for the axial bearing load forces imposed upon rotary joints conveying a pressurised fluid medium, such as steam, by imposing an axial force on the rotary joint housing (20) proportional to the pressure within the rotary joint (10) by use of a distinctively different pressurised medium than that conveyed by the joint, such as compressed air. An expansible chamber motor (38) capable of imposing an axial force on the rotary joint (10) utilises compressed air whose pressure is controlled by a sensing and regulating system responsive to the pressure within the rotary joint (10).

Abstract: It is known to use capillary transport zones to convey drops of patient sample to a test area along a given path. Such a path is defined by a pair of opposing surfaces which are spaced apart by a capillary distance and are held together by means of an adhesive. Plastics materials which are preferred for the construction of such transport zones tend not to be readily wettable and high equilibrium contact angles result. Described herein is a device (110) for providing liquid transport, and a method of making such a device. The device (110) features a capillary transport zone (140) comprising opposing surfaces (134, 136, 170) which are formed from supporting material (130, 132) having unsatisfactory wettability. The wettability is improved by applying a coating (20) of an adhesive to at least one of the opposing surfaces (134, 136, 170).

Abstract: A method for producing a polarizer patterned with a plural number of portions having a polarizing ability or direction of polarization comprising the first step of producing a surface (11) oriented in a pre-determined direction (12) on a substrate (10), the second step of producing a polymerizable molecular layer (14) which comprises polymerizable molecules on the above surface (11), the third step of polymerizing the molecules in said polymerizable molecular layer into a desired pattern (15, 16) and the fourth step of removing the unpolymerized portion (16) of said polymerizable molecular layer (14). For example, the following procedure is repeated on one surface of a substrate (10) to be given a polarizing ability: (a) An organic thin film (11) uniformly oriented in a particular direction (12) is produced by the Langmuir-Blodgett method, (b) a polymerizable molecular layer (14) is produced on the above thin film, (c) the molecules in the polymerizable molecular layer (14) is polymerized into a desired pattern (15, 16) and (d) the portion (16) left unpolymerized of the polymerizable molecular layer (14) is removed. By this treatment, a polarizer having as many orientation directions as the number of repetitions is obtained. The orientational order can also be given by rubbing in place of the Langmuir-Blodgett method.

Abstract: A liquid sprayer (8) includes a housing (11) with a spray outlet (9), an electric pump switch (20) which is movable to operate a spray generating pump (7) and a manual grip (12) defined on the housing (11). A main switch (22) is moveable linearly along the housing (11) between on and off positions, which operate the electric switch (20) to respectively cause and stop pump operation. A safety actuator (30) is moveable to block and permit movement of the main switch (22). The safety actuator (30) has a grippable portion (31) biased (33) to extend outwardly from the housing (11). To operate the pump switch (20), a user squeezes the safety actuator (30) into a switch "on" position in which the safety actuator (30) releases blocking engagement with the main switch (22), and thereby allows the main switch (22) to be moved to its "on" position which operates the pump switch (22) to operate the pump (7).

Abstract: This system according to the invention has plurality of sensors 1 a, 1 b and 1 c, a system control circuit 10 and plurality of actuators 6a, 6b and 6c. In response to an application of state data from the sensors 1a, 1 b or 1 c, the state data is compared with characteristic data in the system control circuit 10. Consequently, it is judged that a fault is caused depending on whether the state data is relatively lower or higher. 
     If a fault is caused, inference of the fault caused is drawn on the basis of a comparison between qualitative data and fault diagnosis knowledge which are stored in the system control circuit 10. Then, it is judged which of elements of a image forming apparatus is abnormal. Accordingly, actuator operating signal is outputted as the results of the judgement.

Abstract: An image forming apparatus (100) comprises a transfer drum (11) for holding paper (P), and can be switched between a monocolor mode in which an image is transferred to the paper (P) held only once and a multicolor mode in which an image having a plurality of colors is transferred thereto such that the colors are fused with each other a plurality of times. A paper feeding path (14), a separating claw (1) for separating from the transfer drum (11) the paper to which the image is transferred, and a cleaner (2) for cleaning the surface of the transfer drum (11) are disposed in that order along the direction of rotation of the transfer drum (11) around the transfer drum (11). When the image forming apparatus (100) is in the monocolor mode, the cleaner (2) is always abutted on the surface of the transfer drum (11), so that the surface of the transfer drum is always cleaned. Accordingly, the cleaner (2) need not be frequently abutted on the surface of the transfer drum (11) or separated from the surface of the transfer drum (11) in the monocolor mode, thereby to make it easy to control the cleaner (2) in the monocolor mode.

Abstract: An adaptive transmission pressure control based on a measured interval of speed ratio progression includes a closed-loop control which compensates for factors that tend to extend the speed ratio progression. The control detects the rate of speed ratio progression during a first portion of the inertia phase of the shift, and employs closed-loop pressure control to maintain the detected rate of progression through completion of the shift. This ensures that the measured progression interval will accurately reflect the relationship between the scheduled pressure and the resulting shift ratio progression, regardless of factors which would otherwise influence the measured shift progression interval. Consequently, the correlation between shift quality and the measured shift progression interval is preserved.
