摘要:
A linear resonant actuator controller for a mobile device having a linear resonant actuator is described. The linear resonant actuator controller comprises a controller output configured to be coupled to a linear resonant actuator; an audio processor having an audio processor input and an audio processor output coupled to the controller output. The audio processor is configured to receive an audio signal comprising speech, to process the audio signal by attenuating the audio signal frequency components at the resonant frequency of the linear resonant actuator with respect to at least some other audio signal frequency components, and to output the processed audio signal on the audio processor output.

Determining a Curie temperature (Tc) distribution of a sample comprising magnetic material involves subjecting the sample to an electromagnetic field, heating the sample over a range of temperatures, generating a signal representative of a parameter of the sample that changes as a function of changing sample temperature while the sample is subjected to the electromagnetic field, and determining the Tc distribution of the sample using the generated signal and a multiplicity of predetermined parameters of the sample.

The present invention is an imaging element which includes a support, an image-forming layer superposed on said support, a transparent magnetic recording layer superposed on said support; and an electrically-conductive layer superposed on said support. The transparent magnetic recording layer is composed of magnetic particles dispersed in a first film-forming polymeric binder. The electrically-conductive layer includes electrically-conductive metal-containing colloidal particles, swellable, smectite clay particles, a first polymeric binder which can sufficiently intercalate inside or exfoliate the smectite clay particles and a second film-forming polymeric binder, wherein the electrically-conductive metal-containing particles and the polymer-intercalated or polymer-exfoliated smectite clay particles are dispersed.

In a method and apparatus for discriminating a coal species, discriminating values of coal species/properties are prepared corresponding to coal ranks, a coal to be discriminated is irradiated with near-infrared rays having different wavelengths, and light of near-infrared rays reflected from the coal is received; Aborbances of the coal are acquired, and the coal species/property discriminating value of the coal is discriminated on the basis of the absorbances and a prescribed calibration curve.

A magnetic recording medium having a recording layer made up of a ferrimagnetic material whose compensation temperature is included within room temperatures and an information recording-reproduction method using the magnetic recording medium. During recording, while a light beam is projected on the recording layer so as to raise the temperature of a recording portion, information is recorded by applying a signal magnetic field from a magnetic head. During reproduction, while a light beam is projected on a reproducing portion of the recording layer so as to raise the temperature thereof, information is reproduced by detecting leakage flux from the reproducing portion by the magnetic head. Thus, during reproduction, no magnetic flux is generated from other portions of the recording layer not irradiated by the light beam. With the arrangement, crosstalk due to leakage flux from adjoining tracks not irradiated by the optical beam can be eliminated. Therefore, track pitches can be made narrower so as to increase recording density of the magnetic recording medium. Further, since crosstalk from adjoining tracks is eliminated, a high S/N can be achieved.

In a magneto-optical recording element comprising a substrate, a magnetic layer and a dielectric layer, the dielectric layer is formed by deposition of a composition comprising Si.sub.3 N.sub.4 and a refractive index-improving agent such as Al.sub.2 O.sub.3 or Y.sub.2 O.sub.3. This dielectric layer has a high refractive index and the enhancement effect is improved. Moreover, this dielectric layer is excellent in the adhesion and resistance characteristics.

Photoluminescent materials useful for detection of infrared light are prepared using a base material, first and second dopants and a fusible salt. The base material is an alkaline earth metal sulfide such as calcium sulfide. Lithium fluoride is used to enhance the interdiffusion of materials. Samarium and a europium compound are used as the first and second dopants for providing electron traps. The photoluminescent material is made according to a process involving heating of the material to a fusing temperature, grinding the material after cooling, and reheating the material to below the fusing temperature, but sufficiently high to repair the crystal surfaces. The material is then placed in a transparent binder and applied to a substrate, or deposited as a thin film directly on a substrate for different uses.
摘要:
Disclosed is a new magnetic storage medium including a layer of amorphous material typically GdDyFe whose Curie recording point (e.g., 120.degree. C.) is lower than its crystallization point (e.g., 350.degree. C.) to enable crystallization to cause variations in its optical properties such as transmittance or reflectivity for thermomagnetic writing. Reversible recordings are set up on the amorphous material layer by a thermomagnetic writing technique, for example Curie point writing, while unchangeable or permanent recordings are set up on the amorphous material layer through laser-activated crystallization of the amorphous material layer.
摘要:
A stimulable phosphor sheet carrying a radiation image stored therein is scanned with stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the radiation energy stored therein. The emitted light is photoelectrically detected to obtain sequential electric signals of respective picture elements of the radiation image. The interference among the electric signals of the respective picture elements which is caused by the light emission response characteristics of the stimulable phosphor to the stimulation is eliminated electrically. The correction is conducted by adding a differentiated value of the sequential electric signals of the respective picture elements to the sequential electric signal of the respective picture elements.
