Abstract: An injection molding composition, having a small fluctuation characteristic and a better characteristic, is provided. The above composition is the injection molding composition comprising a ferrite powder which is a collection of ferrite particles, a first binder and a second binder. A weight and a specific surface area of the ferrite powders are represented by Wp and S, and a weight and a density of the first binder and the second binder is represented by Wb1, Wb2, and Db1, Db2. A hypothetical thickness Tb1 of the first binder is 2.0 to 15.0, and a hypothetical thickness Tb2 of the second binder is 16.5 to 32.0. In the composition, it is preferable that coated ferrite particles coating the outer circumference of the ferrite particles with the first binder and the second binder exist.

Abstract: An indicator device includes a light emitting element for emitting light, and a light conducting plate having a light incidence surface for conducting light from the light emitting element inside thereof and a light output surface, for a lighted indication by the light output surface. The light conducting plate has a triangular recess recessed to form with prescribed recess depths in one planer surface thereof, for light from the light emitting element to be reflected in part. The triangular recess has a recess extremity constituting a single vertex disposed in position on an optical axis of the light emitting element and nearer to the light incidence surface than other end parts thereof. The recess depths becomes shallower as the V-form recess extends from the recess extremity, allowing for an evenness of luminance of light over the light output surface formed on the light conducting plate.

Abstract: A plurality of component layers of thick film forming materials are formed simultaneously on a glass substrate by simultaneously applying a plurality of thick film forming pastes to the glass substrates, or by simultaneously transferring the plurality of component layers of thick laminated film formed on a transfer base sheet from the transfer base sheet to the glass substrate. At least one of the plurality of component layers formed on the glass substrate is patterned, and then the plurality of component layers are burned simultaneously to form a patterned thick laminated film on the glass substrate.

Abstract: A packaged integrated information recording system has a plurality of information recording media radially arranged on a disk substrate. Each of the recording media comprises a liquid crystal recording medium including a liquid crystal-polymer composite layer with polymer balls filled in a liquid-crystal phase, stacked on a first electrode layer and a photoelectric sensor including a second electrode layer and a photoconductive layer formed on a transparent substrate. The liquid crystal recording medium and photoelectric sensor are stacked directly, or through an interlayer on each other while the liquid crystal recording layer and photoconductive layer are opposed to each other. The recording media may also be arranged in a row on a film substrate provided with feed holes on both side edges and received in a closable case such that it can be drawn. Alternatively, the recording media on a film substrate may be received in a packaging case having a window openable and closable by a shutter to unroll the film.

Abstract: An information recording system including a photoelectric sensor having a semiconductive, photoconductive layer stacked on an electrode, and an information recording medium having an information recording layer stacked on an electrode so that information can be recorded on the information recording layer by an electric field or electric charge. The photoelectric sensor and the information recording medium are disposed to face each other, and information exposure is carried out with a voltage being applied between the two electrodes, thereby enabling information to be recorded on the information recording medium. The photoconductive layer of the photoelectric sensor is capable of amplifying an electric field or electric charge given to the information recording medium, so that the intensity of electric field or the amount of electric charge given to the information recording medium can be increased to a level higher than the light energy actually applied.
