Title: Random number generator
Inventor: YANAGIDA TSUGUMINE
IPC: G06F7/58
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To generate a random number by generating a random progression at all times. SOLUTION: An appropriate initial value xn is substituted to a Bernoulli's map 11 and xn+1 is calculated by using both equations; xn+1 =2xn and xn+1 =2xn -1. The value of xn+1 is defined as '0' in a section [0, 1/2] and '1' in the section [1/2, 1], and the progressions '0' and '1' are generated in a 0/1 conversion part 12. A set of initially generated (e) pieces of the progressions are arranged from left to right and inputted to a shift register 13 in the order of generation. Since the progression inputted to the shift register 13 is a binary number, the binary number is converted to a decimal number in a decimal number conversion part 14 and a first random number is obtained.  Thereafter, the generated value of '0' or '1' is added to a right side for the random number, right shifting is performed every time addition is performed, the (e) pieces of the progressions are taken out and the random number is generated. Since the value of the random number obtained in such a manner becomes a non- negative integer whose maximum value is 2<e> , (mod m) is taken, in order to obtain the random number of a positive integer less than an optional positive integer (m).

Abstract: PURPOSE:To recover the display function even when the liquid crystal electrooptic device is exposed to low temperature, then the temperature rises by constituting the liquid crystal electrooptic device by using ferroelectric liquid crystal having a crystal layer which does not decrease in smectic layer interval in a crystal phase. CONSTITUTION:The ferroelectric liquid crystal material 6 is charged hermetically between two electrode substrates 1 and 2 which are arranged at an interval of 2-10mum in parallel to each other. A liquid crystal cell is heated into an anisotropic liquid phase, then cooled on the whole gradually at a speed of 0.1-1.0 deg.C per minute into a chiral smectic C phase. Consequently, liquid crystal molecules are oriented as shown in a figure (b) and the layer direction of the smectic phase 20 crosses the liquid crystal molecules 10 almost at right angles. In such a state, an electric field is applied from the top side of the paper surface to the reverse side and then the liquid molecules tilt to the left at a tilt angle theta as shown in a figure (a). When, the electric field is applied from the reverse surface of the paper surface, the liquid crystal molecules are reoriented as shown in a figure (c). Thus, liquid crystal cells are sandwiched between a 102-directional polarizing plate and an orthogonal polarizing plate, so that a figure (b) shows a drak display and figures (a) and (c) show bright displays.

Title: Error correcting device
Inventor: JIEEMUSU HEDORII UIRUKINSON
IPC: H04N9/80
Filed: 1987-07-31
Abstract: PURPOSE:To correct an error at the step of a composite signal by synthesizing plural sample data spatially and temporally approximating to an error sample and replacing the error sample by interpolating data. CONSTITUTION:An error sample which cannot be error-corrected by an error correcting code, is corrected by an error correcting device. First, a first error correction (frame concealment) is executed. When an error is found in plural samples necessary to the first error correction, a second error correction (spatial concealment) is executed. When the error is found in the plural samples necessary to the second error correction, a third error correction (spatial replacement) is executed. Thus, at a reproducing side, the error correction can be executed by the mode of the composite signal. Consequently, a circuit scale can be minimized different from the effect that an error correcting device is provided at respective components.
