Title: Plural-frame data hiding method and detection method
Inventor: SHIMIZU SHUICHI
IPC: H04N7/24
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent a security hole in advance in the case of applying the data hiding technology for a still image or the like to a moving image or the like by changing embedded processing depending on each time and frame when a frame pattern (mark) consisting of lots of embedded block patterns of some kinds is used to conduct the embedding processing. SOLUTION: Pluralities of contents are made up of pluralities of consecutive frames 15 consisting of sets of single frames 10. In the case of hiding information 30 with respect to contents consisting of pluralities of the frames 15, data are hidden by imbedding pluralities of frame patterns 45 having different block patterns to each of pluralities of the frames 15 to hide the data. A random element R(t) that generates +1, -1 at random depending on time (t) is introduced to the block pattern. Thus, it is prevented that the pattern is estimated by illegal access and it is detected at the same cost as that by a conventional method.

IPC: B23H7/28
Filed: 1982-05-25
Abstract: PURPOSE:To perform finish machining in a short time by means of discharge machining by applying an electrode a fine eccentric motion in a plane vertical to the feed direction and by making a work fitting base movable within a predetermined limit range. CONSTITUTION:An electrode 14 is eccentrically fitted to the machining head 3 of a discharge machining device through a rotary shaft 6, and a fine eccentric motion is applied to the electrode 14 by driving a motor 8. A fitting bed 20 for fitting a work W is made movable in the horizontal plane in relation to a base mount 16, and its movement quantity is limited by the gap length between a shaft 21 and a hole 22 provided on a frame body 4. The electrode 14 is roughly machined under a rough machining condition without being eccentrically moved, then it is finish machined while being eccentrically moved, thereby highly precise finish machining can be performed in a short time.

IPC: H01S5/00
Filed: 1992-04-09
Abstract: PURPOSE:To provide the formation method of an AlxGa1-xAs/GaAs-based microstructure with excellent controllability, uniformity, resistance to damage and workability. CONSTITUTION:The following are crystal-grown continuously on a GaAs substrate 11: a GaAs buffer layer 12; an Al0.3Ga0.7As barrier layer 13; a GaAs quantum well layer 14; an Al0.3Ga0.7As barrier layer 15; and a Ga0.5In0.5P spacer layer 16. Then, a silicon oxide film 17 is deposited; a resist pattern 18 is formed; the silicon oxide film 17 is etched. The Ga0.5In0.5P spacer layer 16 is etched; a pattern by the silicon oxide film is transferred. At this time, the Al0.3Ga0.7As barrier layer 15 is not etched by a hydrochloric acid-based etchant. While the silicon oxide film and the Ga0.5In0.5P spacer layer are used as an etching mask, the Al0.3Ga0.7As barrier layer, the GaAs well layer and the Al0.3Ga0.7As barrier layer are etched sequentially by a dry etching operation. At this time, the silicon oxide film acts sufficiently as a mask because its etch rate at the dry etching operation is small.

Filed: 1979-07-13
Abstract: PURPOSE:To obtain a high-quality picture signal for the motor control device of the VTR, by stabilizing the horizontal synchronous signal of the reproduced signal although the tape transportation speed is varied when the reproducing is carried out. CONSTITUTION:In the case of the fast forward mode of the special reproduction, the 1st and 2nd switch circuits 22 and 27 are switched toward inputs PO and P1 respectively. Thus the control is given to the rotation of rotary head motor 25 by the reference signal which is obtained by giving detection 36 to the speed of tape 33. And in the case of the reverse sending of the tape, circuit 27 is switched toward input P3. And the control is given to the rotation of motor 25 via one step of amplifier 37 and by shifting the center point of the output frequency of voltage control oscillator 32 toward the side lower than the ordinary oscillation frequency of reference signal generator 30. As a result, the special reproduction is possible with the steady horizontal synchronous signal frequency although the tape speed may differ at the biginning and the end of winding.

Title: Pulse frequency detector
Inventor: HORIKIRI JIYUNICHI
IPC: H02P29/00
Filed: 1983-05-20
Abstract: PURPOSE:To speed up the response of detection and to stabilize a speed controlling system byc calculating a forecasting approximate value of an interval between pulses of which frequency can not be detected on the basis of the last and before-last detecting values. CONSTITUTION:A sampling pulse (T pulse) with a period TS is obtained from a clock pulse. A T3' (time from the preceding pulse to be measured to a sampling pulse) counter is reset by the pulse to be measured, counts up the clock pulses and stores the counted value in a T3' buffer every T pulses. An integrator 13 integrates the period TS for every T pulses and an n counter 14 counts up the T pulses. An adder 20 adds the sampling value of an Fn (the frequency of a precedently detected pulse) buffer 18 which is obtained by dividing the value of an N buffer 4 by a period T to the sampling value of an Fn-1 (the frequency of the before-last detecting pulse) buffer 19 and a divider 21 divides the value of the n counter 14 by the output value of the adder 20. The divided value is latched in a buffer 22. The value of the Fn buffer 18 is integrated to the value of the buffer 22 and the integrated value is outputted to a frequency detecting buffer 23 to calculate the frequency.
