Abstract: Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed. The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can by hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers. The hydraulic entangling technique provides a nonwoven fibrous elastic material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance. A smooth surfaced and/or highly absorbent elastic web material, with isotropic strength and recovery in both machine- and cross-directions, can be provided according to the present invention.

Abstract: When an address transition detector (13) detects a transition of an address signal (Add), it produces an address transition detect signal (SATD). The signal (SATD) drives a bit line initializing circuit (6) which in turn initializes paired bit lines (5,  5 ), and ini­tializes the paired output lines (26,  26 ) of a sense amplifier (10). At the same time, a clock signal gener­ator (14) generates a clock signal (φS) for a predeter­mined period of time in accordance with the address transition detect signal (SATD). The clock signal (φS) is supplied to the sense amplifier (10) and a data out­put circuit (11). The sense amplifier (10) is active during a period that the clock signal (φS) from the clock signal generator (14) is in an effective level. The output terminal of the data output circuit (10) is placed in a high impedance state during the period that the clock signal (φS) is in an effective level. During the other periods than the effective level period, the data output circuit (11) produces a signal (Dout) corre­sponding to the data as is read out of a memory cell (7) and outputted by the sense amplifier (10).

Abstract: A method and arrangement for preventing the locking out of devices which are coupled to a bus by either of two of the devices which have become initiator and target devices respectively. The devices arbitrate for control of the bus after the bus enters a bus free phase. The device which wins the arbitration becomes an initiator. A timer in each device on the bus is started upon the initiation of the arbitration. The initiator device is removed from the bus when an elasped time after the timers have been started reaches a pre-determined value. The distributed clock of the invention ensures that the devices coupled to the bus will clear the bus after the initiator has been on the bus for a pre-determined time, thereby obviating skew problems associated with single clocked systems.

Abstract: A one-piece chinstrap-napestrap assembly (36) for a helmet (20) in which a pair of napestraps (42, 44) secured to the nape portion of the helmet interior at laterally spaced locations extend around the lower periphery of the helmet, crossing each other, and pass outwardly through slots (76, 78) formed in the front of the helmet to receive the ends of an adjustable chinstrap (40). Adjustment of the chinstrap (40) at the front of the assembly produces a simul­taneous adjustment of the crossing napestrap portions at the rear of the assembly without the necessity for independent adjustment of the latter strap portions. A padded napestrap retainer (38) secured by straps (68, 70) to the same locations on the nape portion of the helmet is formed with intersecting passages (P1, P2) for receiving the crossing strap portions. The retainer (38) reduces chafing and urges the crossing napestrap portions toward the rear of the helmet (22) when the chinstrap (40) is released to facilitate donning and doffing.

Abstract: Magneto-optical disk recording and reproducing devices and actuators and distance detectors for use therewith are disclosed. The magneto-­optical disk device comprises, in addition to the usual elements, a bimorph type actuator 9, 71 or an electromagnetic actuator 108-115 for driving the magnetic head 8 of the magneto-optical disk device. The bimorph actuator may have a metallic shim 74 whose width varies with respect to the longitudinal distance inversely proportional to the normal function of the first or the second free natural vibration mode. Alternatively, the bimorph type actuator may have a recess 9d formed on a bimorph element 9a to expose a piezoelectric ceramics which outputs a voltage corresponding to the acceleration of the vibration of the actuator; the driver circuit 96 of the actuator reduces the driving voltage when the frequency of the voltage generated at the recess comes into the neighborhood of a higher resonance frequency of the actuator. The optical distance detector comprises a light-emitting diode 14, 16, 31 and a pair of photodiodes 15, 17, 30 which detect the amount of light incident thereon after being reflected at a surface of an object the distance to which is measured. The geometric parameters of the photodiodes are selected in such a manner that the output of a first photodiode decreases as the measured distance increases while the output of a second photodiode increases as the measured distance increases. Thus, the normalized differential output of the two photodiodes, from which the measured distance is determined, varies substantially linearly with respect to the measured distance. In preferred forms, the photodetectors have stepped concentric configurations so that small distances can be measured accurately and efficiently.

Abstract: In an apparatus for measuring particles in a gas, a pressure-reducing system and a particle measuring apparatus are known to be necessary. Common pressure-reducing systems such as pressure-reducing valves have the disadvantage that they contain components which move with respect to one another and produce or absorb particles. It is therefore proposed to fit a supercritical nozzle in the feedline to the particle measuring apparatus as a pressure-reducing system.

Abstract: The subject-matter of the invention is a cartridge album which is intended especially for stamps and comprises an album leaf ring file in a slipcase. The prior art comprises such an album, in which a ring-binding mechanism is attached to the back of a book case, whose front cover closes the ring file. The disadvantage of this mechanism arrangement is the relatively small volume capacity for album leaves with a particular thickness of the latter and particular back width. The object of the invention is therefore an enlargement of the volume capacity whilst maintaining the slipcase. This object is achieved by omitting the front cover of the book case and by connecting the mechanism rings remote from its back to the rear cover of the book case. The advantage of this solution is the approximately 50% increase in the number of album leaves which can be accommodated in the ring file. Additionally, the book back can be opened out away from the rings and used as a pulling tab. <IMAGE>

Abstract: A phase modulated signal is quadrature demodulated (37) using a locally generated (36) signal which has a frequency different from that of the received carrier. 
     The demodulation of a known symbol sequence and of a data symbol sequence respectively result in first and second signal vectors. The first signal vector has in-phase and quadrature components, which are converted to phase values (substantially at the symbol rate). An error signal is formed by comparing (44) the phase difference between adjacent symbols (42,43) with a reference (45). The error signal is averaged (46), and the average value (47) is used to correct (39) the second signal vector. The correction signal may be generated using the received carrier signal.
