A magneto-optical recording medium capable of perfectly masking a mark adjacent to a mark to be reproduced thereby improving a reproduction output. The magneto-optical recording medium includes a transparent substrate, a magnetic reproducing layer laminated on the transparent substrate, a nonmagnetic intermediate layer laminated on the magnetic reproducing layer, and a magnetic recording layer laminated on the nonmagnetic intermediate layer. The reproducing layer has an easy direction of magnetization in a plane at room temperature, and has an easy direction of magnetization perpendicular to a film surface at a given temperature or higher. The nonmagnetic intermediate layer is thin enough to allow magnetostatic bond between the recording layer and the reproducing layer at the given temperature or higher. Instead of the nonmagnetic intermediate layer, a magnetic intermediate layer having an easy direction of magnetization in a plane from room temperature to its Curie temperature may be interposed between the reproducing layer and the recording layer.

A fluororubber composition comprising a fluororubber, a vulcanizing agent and 0.1 to 5 wt. parts of a fatty acid monoamide per 100 wt. parts of said fluororubber. This fluororubber composition is excellent in mold releasability, and a molded article obtained by vulcanizing and molding the composition suffers less deterioration of mechanical properties caused by the addition of an internal mold release agent.
摘要:
A magneto-optical recording medium of a three-layered structure (consisting of a readout layer, an intermediate layer, and a recording layer), capable of double-mask magnetically-induced super-resolution readout, has magnetic properties such that the exchange coupled force between the readout layer (a GdFeCo film) and the intermediate layer (a GdFe film) decrease with increasing temperature, while the exchange coupled force between the intermediate layer and the recording layer (a TbFeCo film) increase with increasing temperature. The magnetic property of the readout layer is transition-metal magnetization dominant, and that of the intermediate layer is rare-earth magnetization dominant. When reading the medium, a region (an intermediate-temperature transfer region) where the magnetization in the readout layer is oriented in the direction of magnetization in the recording layer, and a region (a high-temperature rear mask) where the magnetization in the readout layer is oriented in a second specific direction, are simultaneously formed within a beam spot from a state (a low-temperature front mask) in which the magnetization in the readout layer is oriented in a first specific direction, thus achieving a double mask condition in a single step. Overwrite recording and magnetically-induced super-resolution readout are realized on the same magneto-optical recording medium.

Disclosed is a handle grip to be attached to the shutter button side of a disposable camera, which is equipped with a sprol of film. It comprises: a box-like body whose top plate is long enough to reach the shutter button of the disposable camera, and has an aperture to be in alignment with the shutter button when the handle grip is attached to the disposable camera by inserting the shutter button side of the disposable camera body; a push button fitted in the aperture of the top plate of the handle grip body, the push button being vertically movable, and being spring-biased upward and being adapted to push the shutter button to release the shutter at the end of the downward stroke of the push button when pushed down; a voice sound generator means for electronically generation g artificial voice utterance to attract the attention of children to be snaped; and a switching means to be closed by the push button on the way to the end of the downward stroke, thereby energizing the voice sound generator means.It can generate artificial voice to draw children's attention to the camera at the instant of releasing the shutter, thus timing well the snapping of children.

摘要:
A method of selecting characteristics data for a data processing system from a group of input data for reducing data volume of each input data by said data processing system having a neural network structure or a structure equivalent thereto, where each input data consists of a plurality of said characteristics data. The method includes the steps of storing outputs of said input data; selecting a specific characteristics data of a pair of different input data; exchanging said characteristics data of said input data pair with each other; comparing outputs from said data processing system in response to said input data before and after the exchange of said characteristics data; and removing said characteristics data from said input data in said group, when a difference between said outputs before and after is comparatively small.
