Patent EP-0461911-A2 (EP)
Inventor: NAKAYAMA JUNICHIRO
IPC: G11B23/00
Filed: 1991-06-13
Abstract: A magneto-optical disk (11) according to the present invention has a substrate (12), a recording layer (13) formed on the substrate and an outer layer formed on the recording layer, above which a floating head (15) is hovered. The outer layer is constituted of a protective layer (14), an antisticking layer for head, having a texture formed on its surface and other layers. The magneto-optical disk is designed such that, when rotated at a constant angular velocity, the thickness of the outer layer is substantially inversely proportional to a radial position r on the magneto-optical disk raised to the 1/2nd power. In the formation of the outer layer, a screen whose meshes become gradually finer from the innermost portion toward the circumferential portion of the magneto-optical disk is employed based on the screen printing technique. Further, photo hardening resin is used as the outer layer, and simply by changing a wavelength or irradiation amount of light to be applied thereto, a texture is readily formed on the surface of the outer layer. By the use of the present invention, stable recording, erasing and re-writing operations are achieved, and it becomes possible to prevent the floating head from sticking to the magneto-optical disk and reduce the cost thereof.

Abstract: A method of pre-tenderising meat is provided which involves stunning an animal (1) with a mechanical stunning pistol (6) to cause brain death, infusing a proteolytic enzyme (such as papain bromelain or ficin for example) into the animal under gravity with a syringe (7) whilst the animal's heart is still beating and then bleeding the animal in order to stop the heart beating after a suitable time has elapsed for the enzyme to be distributed within the vascular system of the animal. The enzyme can be infused more easily when the animal is in a prone position, and the process is faster and more humane than prior art processes in which the enzyme was injected into the conscious animal.

Abstract: A method for controlling fines production in an unconsolidated or loosely consolidated formation penetrated by a cased hole. The cased hole is perforated in a manner sufficient to treat a formation internal with a consolidation resin. A thermally stable consolidation resin is injected into the internal and allowed to set. This resin is then drilled out of the hole. Afterwards the casing is reperforated and hydraulically fractured with a fluid containing a fine grain refractory proppant. A resultant fracture is propped by said proppant which removes fines from hydrocarbonaceous fluids produced after initiating a thermal enhanced oil recovery operation in the formation.

Abstract: An electromagnetic relay 38 (FIG. 2) includes a cylindrical core 42 concentrically positioned within a coil assembly 40 and press fit into a frame 50, a resiliently mounted armature assembly 56, and electrical contacts 66,68, one mounted on the armature assembly 56 and one disposed in a fixed relationship to the frame 50. The coil assembly 40 is secured to the frame 50 by the use of extrusions 54 which precludes the need for a core head 24 and crush ribs 26 (FIG.1). After assembling the relay 38, the core 42 is positioned by pressing the armature assembly 56 directly opposite the core 42 until the core 42 travels a predetermined distance beyond the electrical contact point for the contacts 66,68. This invention ensures precise positioning of the functional components and negates the accumulation of manufacturing tolerances in the relay 38.

Abstract: A method for measuring the distribution of radioactivity on a flat sample uses a measuring system operating two-dimensionally. The total measurement of the sample consists of a number of part measurements progressively carried out in one direction of evaluation (scanning). With each part measurement, a strip-like part area is simultaneously and location-sensitively measured in the other direction of evaluation. This method combines the principles of location-dependent measurement, collimation and scanning technique in a particularly advantageous manner since due to the definition of the individual parameters, an optimum adaptation to the type and structure of the samples to be measured becomes possible. <IMAGE>

Abstract: A lens drive apparatus and its producing method are provided in which the productivity is improved and the assembly of components is conducted at high accuracy. In particular, a movable optical system containing an objective lens and a stationary base are coupled by elongated resilient members which serve as suspensions and are provided at both ends with joining members made of a resin material. The resilient members and the joining members are formed in combination by insertion-molding. Accordingly, their assembly can be executed in which such a troublesome work as directly assembling the resilient members of delicate size is eliminated, no particular skill is needed, and less steps are involved for ease of production, thus increasing the productivity. Also, the joining members are comparatively large in size and can thus be mounted at high positional accuracy to both the stationary base and the movable optical system. The joining members and the resilient members are coupled at high accuracy to each other by means of insert-molding. Hence, the positional relation between the stationary base and the movable optical system will highly be enhanced in accuracy.

Abstract: A multirate real-time control system 102 is represented as a set of interconnected functional blocks. Subsets of the functional blocks are defined as subsystems of the multirate real-time system 102, with at least one of the subsystems including a fuzzy logic functional block 150, called a fuzzy logic subsystem. A double buffer 120 interface includes an output buffer 125,126 and a sample and hold buffer 128. The output signal buffer 125, 126 holds output signal values generated by the functional blocks. Prior to executing the computations associated with each subsystem, all input signal values to be used by the subsystem's computations are copied into the sample and hold buffer 128. The input signal values copied into the sample and hold buffer 128 are held invariant during execution of the subsystem's computations, whereby a consistent set of input signal values is presented to each subsystem, including the fuzzy logic subsystem 150. Each fuzzy logic subsystem 150 has a set of membership curves 162, a fuzzifier module 152 for converting crisp input signal values into fuzzy logic values, a connective logic module 154 for combining fuzzy logic values in accordance with defined rules to produced one or more output fuzzy values, an implication operator module 156 for applying each output fuzzy value to a corresponding membership curve to produce an implicated assertion curve, a defuzzifier module 158 for computer a crisp output value as a function of each implicated assertion curve, and an aggregation module 160 for combining two or more crisp output values.

Abstract: In order to determine the occurrence of a stator fault in an induction motor during operation of the motor, the axial leakage flux is monitored during operation of the motor. The occurrence of a stator fault is detected by observing a change in selected harmonic components of the axial leakage. The angular position of the fault with respect to a datum position is determined by noting and recording changes in the axial leakage flux at a plurality of positions distributed symmetrically around the axis of the motor and computing the angular position by triangulation. The axial leakage flux is detected by individual search coils located at said plurality of positions.

Abstract: Methods and apparatus for exposing a sample to ultraviolet radiation are disclosed. The present invention permits a sample contained within a shielded housing to be exposed to a source of ultraviolet radiation and simultaneously observed. The sample rests on a stage that can be moved relative to the source of the ultraviolet radiation while the irradiation is taking place, thus the effects of ultraviolet radiation upon biological materials such as blood can be determined. In a preferred embodiment, upper and lower banks of ultraviolet bulbs are disposed on either side of the stage. The movement of the banks of bulbs and the stage relative to one another is preferably controlled by a set of lead screws. In certain embodiments, the intensity of the emissions of the bulbs themselves can also be altered while continuously observing and irradiating the sample. The invention preferably uses radiation at a wavelength in the UV-B band, between about 280-320 nm or, more preferably, in the UV-A band, between about 320-400 nm.2
