Inventor: NAMURA ITARU
IPC: H01L21/76
Filed: 1994-12-19
Abstract: PURPOSE: To reduce the generation of bird's beaks and to prevent an oxide region, which rises steeply on the periphery of an element region, from being left by a method wherein a thin Si film is formed on the side-walls of a mask pattern, this thin Si film is oxidized by a selective oxidizing process and an Si oxide film formed by the oxidation of the thin Si film is removed by etching. CONSTITUTION: A mask pattern 4 for selective oxidation is formed on an Si substrate 1 and films of two layers of a first film 5 capable of forming an oxide film and a dummy film 6 thicker than the film 5 are deposited on the substrate 1 in such a way as to cover the pattern 4. These films of the two layers are etched by anisotropic etching and films 5a and 6a of two layers are left only on the sidewalls of the pattern 4. The dummy film 6a of the left films of the two layers is removed by isotropic etching and the surface, which is not covered with the pattern 4, of the substrate 1 is selectively subjected to thermal oxidation. An oxide film 8 formed by oxidizing the pattern 4 and the film 5 is removed by isotropic etching.

Abstract: PURPOSE:To prevent a low-temperature burn during sleeping and the like in an electronic carpet. CONSTITUTION:An electronic carpet is divided into a plurality of heating units H1, H2,... and at least one set of piezoelectric element 10 is arranged in respective heating units H1, H2,.... The condition of appearance of a man is discriminated into a seating condition, bending and lying condition, extended lying condition and the like from the configuration of pressurizing areas K, in which piezoelectric elements, outputting a pressurized signal, are distributed, by an appearance consition discriminating means 21 while the acting condition of a man is discriminated by an acting condition discriminating means 22 into an awaken condition and a sleeping condition from the change of a voltage in the pressurizing areas K. Supplying electric power for a pressurizing areas K and surrounding areas N are controlled individually by operating through fuzzy inference by an operating means 23, in which the supplying electric power for the pressurizing areas is set so as to be smaller than a predetermined value under the sleeping condition while the supplying electric power for the surrounding areas is set so as to be bigger than the pressurized areas while considering the appearance condition and the acting condition of the man as leading conditions and considering the supplying electric power for the pressurized areas K and the surrounding areas N as the following conditions. According to this method, low-temperature burn can be prevented while maintaining warm-keeping function.

Title: Method and instrument for measuring property of fluid in container
Inventor: NAGAMINE KINGO
IPC: G01N9/32
Filed: 1992-11-02
Abstract: PURPOSE:To directly, continuously, and automatically measure the viscosity of a fluid in a container by inserting a measuring body having a prescribed shape into the fluid in a prescribed attitude and finding the relative speed of the measuring body against the fluid when the measuring body is rotated at a fixed speed. CONSTITUTION:When a supporting body 10 is rotated at a fixed speed by means of a driving motor 22, a first tubular body 30 and measuring body 31 rotate together with the supporting body 10 in the fluid 2. When the body 31 rotates, the body 31 receives a fixed drag from the fluid 2 and a drag computing element 61 calculates the drag the body 31 receives from the fluid 2 and outputs the drag to a CPU 63. A second tubular body 40 also rotates as the supporting body 10 rotates and, when the body 10 rotates, a rotor fitted to the front end of the tubular body 40 receives a pressure from the fluid 2 and rotates. A relative speed computing element 62 calculates the relative speed of the measuring body 31 against the fluid 2 and outputs the relative speed to the CPU 63. The CPU 63 calculates the coefficient of viscosity of the fluid 2 from the inputted drag of the body 31 and relative speed of the body 31 against the fluid 2.

Title: Voice recognition device and voice recognition method
Inventor: AOSHIMA SHIGEKI
IPC: G10L15/22
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To improve recognition capacity by making best use of recognized results of the past, when voice is re-input. SOLUTION: A restatement judging part 20 carries out inter-input-pattern matching between this time input voice pattern and the past input voice pattern to judge whether this time vocalization is a restatement vocalization or not. A recognition processing part 30 carries out recognition matching of this time input voice pattern with the standard pattern to select a recognition candidate. If the result of the restatement judging part 20 is not the restatement vocalization, the recognition candidate selected this time is output as the recognized result as it is. In the case of the restatement vocalization, the adjusted recognition candidate is decided, based on double matching results using both of the past recognition candidates stored in a recognition candidate registration part 32 and the recognition candidate is obtained by the processing of this time.

The position comparison of a signal in which the output of the frequency divider 4 is latched at the FF5 of the master clock with a pulse in which the leading edge of a reference clock is differentiated by a differentiation circuit 1 using the FF of the master clock is performed at a decoder circuit 6. When the phase leads, a timing signal in which the pulse is reduced at the time of switching and switching back by the selector 3 is generated by using the clock 2-frequency divided with the switching and switching back signal, the output of the circuit 1, and the FF of the master clock, and it is added on an output state inversion circuit 7 using the FF of the master clock, then, the phase is lagged, and when the phase lags, the phase is advanced by generating the timing signal to increase the number of pulses.
