Patent EP-0489913-A1 (EP)
Inventor: NISHIDAI HAJIME C O OMRON CORP
IPC: G06N7/04
Filed: 1990-07-10
Abstract: In a fuzzy control apparatus capable of changing the rule during its operation, a sample-and-hold circuit (13) stores the fuzzy inference output of a fuzzy control circuit (10) immediately before the rule change; and an output switching circuit (20) synthesizes a fuzzy control output from the fuzzy inference output stored immediately before the rule change and the fuzzy inference output after the rule change so that the ratio of the fuzzy inference output immediately before the rule change to the fuzzy control output may decrease with the lapse of time from the rule change, in other words, the ratio of the fuzzy inference output after the rule change to the fuzzy control output may increase, and outputs only the fuzzy inference output after the rule change as the fuzzy control output after a predetermined period of time from the rule change. In this manner, the drastic change of the output at the time of the rule change can be prevented and smooth switching can be made.

IPC: H04B5/00
Filed: 1991-01-09
Abstract: A regenerative RF bi-directional communications system (10) is provided for establishing RF coverage within a RF block tunnel area (12). The system uses a plurality of cascaded amplifier stages (18) for periodically regenerating signals which are transmitted and received along a series of radiating cable length (16) which link base station transceivers (14) to hand-held or like mobile communication units. An intermediate frequency distribution system is used so that the required level of amplification is achieved through the several cascaded amplifier stages (18) at the level of low-power IF signals generated from the original RF signals in conjunction with the appropriate oscillator and pilot signals. The IF distribution system restricts the cascading effect occurring due to the plurality of cascaded amplifier stages on the relatively low-power IF signals, thereby producing a negligible amount of intermodulation.

Abstract: The gantry (10) of a scintillation camera has a counterbalancing means (22) which mechanically counterbalances the gantry about two parallel axes. One axis (13) passes through the detector (12). The other axis (25) is a tilt axis about which a gantry structure which supports the detector may be tilted. The gantry is also counterbalanced about an axis of rotation. 
     The camera has means for detachably securing a collimator (24) to the detector and means for identifying the collimator which is so secured. The counterbalancing means is automatically adjusted to counterbalance the gantry in accordance with the collimator which has been attached to the detector. In the preferred embodiment, the gantry is counterbalanced even when no collimator is secured to the detector.

Inventor: BAUR FRITZ
IPC: F16L55/163
Filed: 1991-04-19
Abstract: The sealing of buried, unsealed pipeline sections causes considerable difficulties, particularly in the case of nominal widths of 700 mm and less, since it is no longer possible to move through pipes of such small internal diameters. Since the pipeline sections are in use, the sealing of the internally accessible parts of the butt joints with plastic compounds causes difficulties. According to the invention, an elastically deformable, annular sealing element (having an external diameter which corresponds in the unstressed state essentially to the diameter of the butt joint to be sealed) is thus in each case compressed in the radial direction onto an external diameter which is smaller than the unobstructed internal diameter of the pipe, in order to seal the prepared butt joint between two pipe pieces. The sealing element, compressed in this manner, is then pushed into the pipeline section and, on the butt joint to be sealed, is pushed into the butt joint by the application of a force acting radially outwards, essentially over the internal circumference. In this way, it is possible to utilise the advantages of the compression seal, which can be fitted even in the case of a pipe carrying water, for sealing pipeline sections through which one cannot pass. <IMAGE>

Abstract: An intake air filter for internal combustion engines has a flat, exchangeable filter insert (20) having a cross-flow in operation and a sealing strip (22) arranged on the periphery for end face sealing on a shoulder (15) of the filter housing (11). It can be inserted into the filter housing (11) via a narrow side (17), the sealing pressure being provided by way of a closure (50) which has two sliding wedges (51), (53). In order to ensure that when the sealing pressure is applied the sealing strip (22) is not laterally displaced in relation to the shoulder (15) of the filter housing (11), the closure (50), which is designed as an essentially open frame (30), receives the filter insert (20) in an exchangeable manner. The closure (50) is provided with detent cams (40), (41), which serve to fix the frame (30) in an expanded position whilst changing the filter insert (20). In addition the side walls (25), (26) of the filter housing (11) and the side walls (45), (46) of the frame (30) are inclined in a wedge shape in order to prevent increased friction between the adjacent surfaces when inserting and removing the filter. …<IMAGE>…

Abstract: A nitride or carbonitride layer is formed on the surface of a metal material as follows: 
     A treating agent composed of a refractory powder of alumina or the like and a powder of a metal for forming a nitride or a carbide or an alloy thereof is disposed in a fluidized bed furnace; the treating agent is fluidized to form a fluidized bed by introducing an inert gas; the fluidized bed furnace is heated to a temperature of not higher than 700 C; an activator of a halogenated ammonium salt is intermittently supplied into the fluidized bed at a rate of 0.001 to 5 wt%/hour based on the total amount of the treating agent; and the metal material to be treated is disposed in the fluidized bed during or after any of the above steps. 
     For example, a nitride layer composed of only a metal for forming a nitride which contains almost no Fe-N is formed on the surface of iron steel even at a temperature as low as not higher than 700 C. The layer is very hard and efficient in wear resistance, and the toughness of the base metal is hardly lowered.
