Abstract:
PROBLEM TO BE SOLVED: To provide a transfer sheet for forgery preventing indication which exerts a high security effect and improves durability and which makes it possible to give the forgery preventing indication to various objects at a low cost and reliably. SOLUTION: A transparent film is laid on a base sheet 2 for peeling off, with an easy-to-peel layer 3 interlaid. The transparent film is an angle-dependent film 4 of which the visual effect varies according to an angle of sight. An angle-dependent layer 7 formed of angle-dependence ink which makes the color of reflected light vary according to the angle of sight and a fluorescent printed layer 6 formed of fluorescent ink which emits the fluorescent light in a visible range in reaction to a light beam of a prescribed wavelength are provided for the angle-dependent film 4, and a transfer adhesive layer 8 is formed on the side of the angle-dependent film 4 whereon the angle-dependent layer 7 and the fluorescent printed layer 6 are formed.

Abstract:
A method is provided for estimating a temperature distribution history in the case of line-heating flat-plate steel by high frequency induction. The method of estimating the temperature distribution history includes a first step of measuring a history of temperature distribution that is generated when a test piece of sheet steel is spot-heated; a second step of analyzing an induction current distribution that is generated when the sheet steel is spot-heated; a third step of expressing the induction current distribution by an approximation equation of the initial induction current distribution at an initial temperature and temperature dependent correction factor of the initial induction current distribution, and identifying the initial induction current distribution and the temperature dependent correction factors based on the temperature distribution history and the induction current distribution; a fourth step of analyzing internal heat generation from the initial induction current distribution, the temperature dependent correction factor, and a temperature dependency of electrical resistivity of the sheet steel; and a fifth step of analyzing the temperature distribution history generated during the line heating by applying the internal heat generation to the sheet steel while the internal heat generation is being moved. According to the method, the temperature distribution history in the case where the flat-plate steel is line-heated by high frequency induction can be efficiently estimated at high precision.

Abstract:
Provided is a stream signal transmission device that can eliminate transmission delay fluctuation with a fast change such as network jitter with high accuracy and synchronize a plurality of streams. The stream signal transmission device includes at least one reception unit that receives a stream signal to which a time code is attached from a network, at least one extraction unit that extracts the time code from the stream signal received by the reception unit, and at least one delay control unit that determines an output time by adding a predetermined fixed delay to a time indicated by the time code extracted by the extraction unit, and outputs the stream signal received by the reception unit after holding the stream signal up to the output time.
Abstract:
A magnetic head and a magnetic disk drive using the same is disclosed. The head is capable of increasing efficiency in changing the flying height of an element portion by heat generation of a heater in the magnetic head using the heater as well as capable of suppressing the change of the flying height of the element portion at the time of recording.
