Abstract: An open-back baffle loudspeaker having a higher baffle cut-off frequency and a lower resonant frequency of possibly 25-50Hz. The loudspeaker is made with a relatively high "Q" (e.g., between 2 to 4) so that the effect of the "Q" on amplitude counteracts the effect of baffle roll-off, thus causing the amplitude of the output of the loudspeaker to remain substantially constant from the baffle cut-off frequency to the resonant frequency. The result is a loudspeaker which can more faithfully reproduce relatively low frequency sounds.

Abstract: Method for the unification of the form of the deflection lines of the roll mantles (13,23) at the nip (N) formed by an adjustable-crown roll (10) with its counter-roll (20). The bearing spacing (L₀) of the said counter-roll (20) is substantially larger than the corresponding bearing spacing (L₁) of the adjustable-crown roll (10). The load in the nip (N) between the rolls (10,20) is produced by means of load forces (F) which are effective facing the bearings (22a,22b) of the counter-roll (20). In the method, by means of devices fitted inside the bearing spacing (L₁) of the mantle (13) of the adjustable-crown roll (10) and inside the mantle (13), a compensation moment (M k ) is produced which loads both of the end regions of the roll mantle (13), the magnitude of the said moment (M k ) being arranged by means of a compensation force (F k ) such that the roll mantles (13,23) will have substantially uniform deflection lines at the nip (N) between the counter-roll (20) and the adjustable-crown roll (10).

Abstract: In a voltage detector using an electro-optic material whose refractive index is changed by a voltage developing in a gelected area of an object under test, a light beam emitted from a light source is applied to a beam splitter, where it is split into a light beam advancing along a reference optical path and a light beam advancing along an optical path extended to an optical path length changing means made of the electro-optic material, and the light beams are returned from the reference optical path and the optical path length changing means after reflection to the beam splitter, where they are caused to interference with each other to provide an output light beam which is applied to a detector. The efficiency of light beam utilization is improved, and the voltage developing in the selected area of the object can be detected with high accuracy.

Abstract: CO is recovered from a CO-containing gas by contacting a CO-containing gas with a non-aqueous CO-­absorbing solution comprising 3 to 6 moles/ℓ of hexametaphosphateamine, 1 to  4  moles/ℓ of cuprous chloride, 0.1 to 1% by weight of water and an organic solvent, thereby absorbing CO into the CO-absorbing solution from the CO-containing gas, and then atomizing the CO-absorbed solution, thereby stripping CO from the CO-absorbed solution and obtaining a CO gas, while recycling the CO-freed absorbing solution to the absorp­tion of CO from the CO-containing gas with remarkable reduction in the corrosion rate on apparatus materials without impairing the CO absorption, and use of a two-­fluid, simultaneous atomizing means for atomizing the CO-absorbed solution together with the vapor of the organic solvent can improve the CO stripping rate, and reduce the CO recovery cost.

Abstract: A method for performing an input/output process containing a programmed input/output (PIO) instruction in a multiprocessor system including at least two processors each having an associated I/O bus with I/O devices connected thereto. The method comprises the steps of storing a unique address and a bus location for each I/O device in a device location table, determining the address of a referenced I/O device prior to performing the PIO instruction, reading the corresponding I/O bus location of the referenced I/O device from the device location table and executing the input/output process on the prescribed processor associated with the I/O bus to which the referenced I/O device is located. The method is used in conjunction with a task scheduler including a process control block for each scheduled process. When the PIO instruction references a device on the local I/O bus, the input/output process is executed normally. To execute the input/output process on a remote processor, a locked descriptor identifying the remote processor is placed in the process control block for that process. The input/output process is then scheduled for execution on the remote processor.

Abstract: An acceleration sensor comprises a housing having a magnetically permeable element, such as a steel washer, secured thereto proximate with an end of a cylindrical passage formed therein; a magnetic sensing mass in the passage which is displaced in response to acceleration of the housing from an initial position within the passage proximate the steel washer to a second position within the passage when such acceleration overcomes the magnetic bias of the sensing mass towards the steel washer; a pair of electrically conductive rings encompassing the passage so as to provide magnetic damping for the sensing mass during the displacement thereof; and a pair of beam contacts projecting from the housing into the passage so as to be bridged by the sensing mass when the sensing mass is displaced to the second position within the passage. The accelerometer further comprises a pair of oppositely-wound electrical coils encompassing the passage proximate the initial position and the second position of the sensing mass therein, respectively. Upon the delivery of a direct current to the coils, the sensing mass is magnetically biased to the second position within the passage, whereby the beam contacts are bridged by the sensing mass to confirm the operability of the sensor.
