Title: Optical element
Inventor: ISHIHARADA MINORU
IPC: G02B1/04
Filed: 1993-10-27
Abstract: PURPOSE:To provide an optical element simple in structure, lightweight and low-priced with little optical distortion such as double refraction and optical elasticity even if being made large-sized by providing a transparent elastic body having a glass-transition temperature being the room temperature or lower, as a transparent light transmission medium. CONSTITUTION:The inside of a cubic glass case is diagonally partitioned, and the partitioned place is provided with a translucent reflecting film 2. A transparent elastic body 3 is then filled in the half of the partitioned glass case 1. The transparent elastic body 3 is formed out of a material selected out of polymer materials with the glass-transition temperature being the room temperature or lower. The glass case 1 can be formed not only out of an inorganic glass but also of transparent plastic material such as acrylic resin. As the transparent elastic body 3, a polymer or copolymer of acrylic ester with the glass-transition temperature in the case of being polymerized as the polymer material being the room temperature or lower is ideally used from the viewpoint of transparency. It is desirable to cross-link the transparent elastic body 3 in order to prevent fluidity.

Title: Learning method of neural network
Inventor: GOTO MAKIO
IPC: G06N3/00
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To make efficiently peformable an optimum learning without reaching a local solution, by performing learning by using a 1st error evaluation function where priority is given to the learning speed, and then switching the function to a 2nd error evaluation function where priority is given to the calculation precision and then carrying out learning again. SOLUTION: An input pattern to an input layer (a) is shown first to obtain an output pattern corresponding to it. Then, errors of respective units based on the error evaluation function are calculated from the output pattern and tutor data. Then, a coupling load connected to a unit which outputs a color- corrected output signal C is considered, and the variation of load coupling connected to the color-corrected output signal C is found. Similarly, variations are found as to color-corrected output signals Y and M. This process is performed for all input patterns. When necessary end conditions are met, the learning is stopped temporarily. Then a new error evaluation function which minimizing the mean error is set and the learning is restarted. Namely, the coupling load unchanged and regarded as an initialization load and the learning is restarted.

IPC: G06G7/163
Filed: 1992-10-06
Abstract: PURPOSE:To make highly accurate and diversified arithmetic possible with a small-scale circuit by outputting the multiplied result by operating calculation with voltage difference among respective capacitances. CONSTITUTION:This multiplication circuit is provided with capacitances C0-C3 with different capacity connected to an output terminal, an nMOS is connected at the source to one terminal of respective capacitances C0-C3, a pMOS is connected at the drain, the drain of the pMOS is grounded, and the source of the nMOS is connected to a common input voltage Vi.

When voltages to be impressed to the respective capacitances C0-C3 are defined as V0-V3, a voltage V0 is generated at out. Therefore, unit capacity (c) is decided and C0-1c, C1-2c, C2=4c and C3-c8 are set so that any arbitrary integer arithmetic can be performed by opening/closing the SW0-SW3.

Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To improve the ratio of a signal with respect to noise and to avoid the necessity of a noneconomical p-bit multiplier by converting two differential analog signals of a microphone into a one-bit signal and synthesizing two one bit signals in DSM. SOLUTION: A sound signal processor contains a differential microphone 50 for generating a differential pair of analog signals.

The two one bit signals are synthesized in a digital sigma modulator 58 having the gain which can be controlled. Then, a non-differential one-bit signal is generated, and it is used in a one-bit audio mixer 60, for example. Thus, the ratio of a signal with respect to noise is improved, and the necessity of the non-economical p-bit multiplier can be avoided.

Title: Semiconductor memory device
Inventor: YAMASHITA MASAYUKI
IPC: H01L29/788
Filed: 1986-12-09
Abstract: PURPOSE:To obtain stable write and read characteristics without the variation of a manufacturing process and the lowering of the degree of integration by changing the channel width of a transistor selecting memory cells and compensating electrical characteristics in an electrodes generated by the difference of the physical positions of each memory cell. CONSTITUTION:Width is widened toward the central direction of N<+> diffusion layers 14 and gate polysilicon 13 in order to change the channel width W of each selecting transistor. When voltage is applied to the gate polysilicon 13d, a plurality of memory cells through an aluminum wiring 18d are selected. When high voltage is applied to either of word-line polysilicons 21, one memory cell in memory cells of interest is selected. Since the channel width of a selecting TR with the gate polysilicon 13d is increased, an internal resistance value at the time of the conduction of said selecting TR is reduced. Consequently, the increasing section of the source potential of the selected memory cell is compensated by the rise of the drain potential of said memory cell though the source potential of the selected memory cell is elevated. Accordingly, write currents equal to a memory cell 26 near to contact holes 22, 23 can be supplied.
