Title: Method and device for embedding information
Inventor: KATSUTA NOBORU
IPC: G06Q50/10
Filed: 1992-02-25
Abstract: PURPOSE:To embed information in video signals almost without degrading video concerning a device for preventing a video software from being illegally copied. CONSTITUTION:A feature area detector 1 detects an area satisfying a decided condition from an input signal (a) and transmits a detected signal to an interpolation processing device 2 and a temporary storage device 4. At the interpolation processing device 2, the interpolation signal of a feature area is generated and transmitted to a selector 5. On the other hand, embedding information (b) is encoded for error correction by an error correcting encoder 3 and stored in the temporary storage device 4. Each time when the detecting signal is inputted from the feature area detector 1, the temporary storage device 4 outputs embedding information to the control part of the selector and corresponding to that signal, the selector 5 selects either the input signal or the signal from the interpolation processing device 2 as an output signal (c).

Title: Winding method for thread string
Inventor: IMAE MASAZUMI
IPC: B65H54/02
Filed: 1995-02-01
Abstract: PURPOSE: To prevent a ribbon from forming by setting a safety route for avoiding the ribbon with a priority order based on the position and the strength of the ribbon, selecting the combination of the traverse jump points and the safety route in all the route from the higher priority toward the lower one, and controlling the traverse speed. CONSTITUTION: A ribbon is formed when a wind rate is an irreducible fraction having an integer numerator (n) and an integer denominator (m). Though the ribbon strength (P) is P=D/m (D is a winding diameter), increase in the winding diameter (D) near a traverse pump point is little so that the ribbon strength (P) approximates to 1/m and the priority order of the traverse jump becomes the value (m) itself. A safety route for avoiding the ribbon is decided from the interior division point with consideration to the ribbon strength and the intermediate two division points of the ribbon position. Traverse jump is set by a control device 8 for winding it at the constant wind rate and avoiding the ribbon so that speed of a motor 4 of a traverse mechanism 3 is controlled.

Title: Muting control system for acoustic signal
Inventor: IWAHASHI MASAYOSHI
IPC: G11B20/10
Filed: 1985-02-27
Abstract: PURPOSE:To prevent generation of a drift and to reduce the cost by outputting a mute signal when the count of an up-down counter reaches the predetermined 1st value and interrupting the mute signal when the count reaches the predetermined 2nd value corresponding to the synchronous period. CONSTITUTION:When the count of an up-down counter at an asynchronous period reaches N, a signal starting the muting is outputted from a flip-flop circuit 15. Then after the mute signal is outputted, the mute signal is outputted until the count content of the up-down counter 14 subjected to down-count at the synchronous period agrees with 0, and the mute signal is interrupted when the content is coincident with 0. Even when the synchronous/asynchronous state takes place respectively in a short time, the muting is not applied excessive ly, noises on the acoustic feeling are reduced, and when the circuit is integrated, for example, generation of drift is prevented and the cost is reduced.

Abstract: PURPOSE:To easily and inexpensively generate fine vibrations by using an acoustic signal outputted by an acoustic signal generation device by processing the acoustic signal by an acoustic signal processor into control data for an exciter. CONSTITUTION:When the acoustic signal generation device 1 generates the acoustic signal (a), the acoustic signal (a) is sent to the acoustic signal processor 5 and passed through a filter 7 and then a variation quantity signal (b) detected by a differentiator 8 is converted by an A/D converter 9 to generate data on the variation quantity in the form of a function of time, so that the data signal (c) is inputted to a computing element 10. The computing element 10 performs arithmetic operation for conversion into the actual operation value of a stepping cylinder 2 according to the data signal (c) and the obtained arithmetic value is sent as a control signal (d) to a cylinder driving device 3. Consequently, the stepping cylinder 2 is driven with the driving signal (e) from the cylinder driving device 3 which is based upon the control signal (d) to vibrate an object 4.

Title: Pressure detecting photosensor
Inventor: FUKAYA NAOKI
IPC: G01L11/00
Filed: 1987-02-20
Abstract: PURPOSE:To widen the detection range of pressure and to hold reliability for a long period by displacing a magnetic means by variation in pressure and converting it into variation of the magnetic field in a magneto-optical element. CONSTITUTION:When liquid or gas outside a partition wall 6 varies in pressure, an elastic film 8 is displaced according to the pressure variation. When the pressure outside the wall 6 rises, the film 8 projects inside the wall 6 and when the pressure falls, the film 8 projects outside the wall 6. A permanent magnet 7 is displaced upward and downward according to the displacement of the film 8 and the relative position relation between the magnet 7 and magneto- optical element 3 also varies. Thus, when the magnetic field penetrating the element 3 varies, the plane of polarization of light transmitted therein rotates. The rotation of the plane of polarization is detected by a photodetector 5 through an optical fiber 4 to detect pressure variation outside the wall 6. The pressure detecting element itself has no mechanical fatigue because of the structure of the sensor, so its life can be prolonged and the pressure detection range depends upon the property of the film 8, so the film 8 is selected to measure pressure over a wide range.
