Abstract: In producing a multilayer-coated powder by coating the surface of a base powder of a metal, metal oxide, etc. with two or more layers of a metal oxide or the like, the films of a metal oxide or the like are formed through decomposition, etc. from a metal salt as an inexpensive material. This is attained by making the powder particles not to be attacked by acids, etc. when the metal salt decomposition or the like, which yields an acid, etc., is conducted. The multilayer-coated powder is characterized in that the multilayered film comprises at least one layer consisting of a metal hydroxide or metal oxide film formed by the hydrolysis of a metal alkoxide and, as a layer disposed on the outer side of that layer, a coating film consisting of a metal hydroxide or metal oxide film formed by a reaction, e.g., neutralization or pyrolysis, of a metal salt. Upon heating, the metal hydroxide or metal oxide film formed by the hydrolysis of a metal alkoxide becomes a dense metal oxide film.

Abstract: A method is provided for accurately estimating the speed of mobile stations in a cellular communications system. Taking into account the Doppler shift of the information in a received burst, a frequency offset value is calculated for each received burst. For each burst, a signal quality value is calculated, which is compared with a predetermined signal quality threshold level. The absolute value of each of the frequency offset values whose signal quality value meets or exceeds the predetermined signal quality threshold is obtained. The frequency offset values whose signal quality values do not meet the threshold level are disregarded. The total mean of all of the absolute frequency offset values is then calculated. The total mean value is used to accurately estimate the speed of the mobile station. Consequently, the speed of faster and slower mobile stations can be readily distinguished, and a hierarchical cell structure can be effectively used to increase capacity and reduce handovers in a cellular communications system.

Abstract: An automatic shaft lock is incorporated into the transmission or drive components of a power driving tool of the type commonly used to tighten or loosen threaded fasteners, for example. The automatic shaft lock operates to prevent an externally-applied rotational back--force or back-torque, such as results from use of the tool to manually tighten or loosen a fastener, from being transmitted all the way through the drive components to the tool's motor or armature shaft. The shaft lock also effectively reduces the amount of back- torque, functioning automatically in either rotational direction, due to being disposed at an intermediate location in the drive train, between an intermediate gear enmeshed for driving rotation with the tool's armature shaft and an output gear enmeshed in a driving relationship with the tool's output shaft.

Abstract: An arcing fault detector band pass filters the ac current in a protected circuit to generate a sensed current signal with pulses having an amplitude related to the step increases in current produced each time an arc is struck. The envelope of this pulse signal is tracked by a first, slow tracking circuit or envelope detector having a first, long time constant and a second, fast tracking circuit having a second, shorter time constant. When the second tracking signal generated by the second tracking circuit falls below a predetermined fraction of the first tracking signal of the first tracking circuit, a charge pulse modulator generates a pulse of a size which is a function of the amplitude of the most recent pulse in the sensed current signal. When a time attenuated accumulation of the charge pulses maintained on an integrating capacitor reaches a preselected level, an output circuit generates an arcing fault indication.

Abstract: A liquid discharge head comprises heating members for generating thermal energy to create bubbles in liquid, discharge ports forming the portions to discharge the liquid, liquid flow paths communicated with the discharge ports, at the same time, having bubble generation areas for enabling liquid to create bubbles, movable members arranged in the bubble generation areas to be displaced along with the development of the bubbles, and regulating members to regulate the displacement of each of the movable members within a desired range, and with energy at the time of bubble creation, the liquid being discharged from the discharge ports. For this liquid discharge head, each of the liquid flow paths holds bubbles while bubbling, at the same time, being provided with gaps arranged on the sides of the movable member to allow the liquid on the upstream thereof to flow into the bubble generation area while bubble disappearing. With the structure thus arranged, the meniscus is drawn into the liquid flow path quickly immediately after the bubble disappearing of bubble begins, and then, with a strong force of the meniscus, the trailing portion of the liquid column connected with the discharged droplet is cut off outside the discharge port, hence making the number of satellites smaller for the enhancement of the quality of prints.

Abstract: An acoustic droplet emitter which a liquid level control plate has a lip in intimate contact with the free surface of a liquid is constructed. The liquid level control plate also has an effective aperture diameter at the exit edge of the plate which is larger than the effective aperture diameter at the lip. This reduces the pressure sensitivity of the free surface of the liquid and allows for the free surface of the liquid to be effectively pinned at the bottom surface of liquid level control plate for wider variations in pressure than using conventional methods.
