Title: High-aspect-ratio fine-pattern formation method of organic film
Inventor: MIZUSHIMA AKIKO
IPC: H01L21/027
Filed: 1991-10-11
Abstract: PURPOSE:To provide the high-aspect-ratio fine-pattern formation method, of an organic film, wherein the generation of the mixed layer of a photosensitive layer with the organic film is prevented or eliminated in a method wherein the organic film is dry-etched by using the photosensitive layer which has been patterned. CONSTITUTION:An organic-film layer 2 is formed on a semiconductor substrate 1; it is denatured after the surface of the organic film has been irradiated with deep ultraviolet rays. Thereby, it is possible to prevent generation of the mixed layer with a photosensitive layer 3 formed thereon. In succession, the organic film is worked fine by executing an oxygen-plasma etching operation while the photosensitive layer patterned by an exposure operation and a developing operation is used as a mask. Alternatively, the photosensitive layer is patterned; after that, a dry etching operation is executed by CF4 gas; in succession, the organic film is worked fine by executing an oxygen-plasma etching operation. Lastly, when the photosensitive layer is removed, the high-aspect-ratio pattern of the organic film is formed Thereby, the high-aspect-ratio fine pattern of the organic film can be obtained with good accuracy.

Filed: 1984-12-15
Abstract: PURPOSE:To eliminate friction at a seal section of a rod, by sealing one side end of a rod and a pressure vessel and an intermediate part thereof with berrows separately to fill two fluid chambers thus formed with a pressure fluid. CONSTITUTION:One side end of a rod 10 and a pressure vessel 30 is sealed with a first berrow 40 and an intermediate part thereof 10 done with second and their berrows 60 and 70 separately to form first and second fluid chambers 50a and 50b, which are both filled properly with a pressure fluid.

Title: Correction of zero point error of torque sensor
Inventor: MORI TAKUJI
IPC: G01L25/00
Filed: 1993-10-25
Abstract: PURPOSE:To make an apparatus immediately return from an abnormal state and correctly correct an error of a zero point by recognizing the application of a torque from an inclination of adjacent measuring values of a plurality of sampling data and correcting the zero point using a measuring value when no load is applied, as the reference point. CONSTITUTION:A torque is measured at a constant sampling cycle (t) from a time point 1. The cycle (t) is shorter than the shortest continuing time of the applied torque and n.t is set to be longer than the longest continuing time of the torque while (n) is a continuous sampling number of times. When a difference of a pair of adjacent measuring values exceeds a constant value + or -a, the application of the torque is recognized. For instance, when the measurement is started at the time point 1, the measurement is continued at time points 2, 3 because the difference of the measuring torque values is within + or -a. The application of the torque is recognized at a time point 4 when the difference exceeds + or -a. Then, a measuring value at the time point 3 without any load applied is newly set as the reference point to correct error of a zero point. Accordingly, it is prevented that the applied torque is erroneously recognized as the error of the zero point and the zero point is corrected.

Title: Tire having muffling performance
Inventor: MIURA YOSHIAKI
IPC: B60C11/11
Filed: 1986-11-07
Abstract: PURPOSE:To eliminate a knocking sound in a car tire for a snow-covered road, by dividing the tread into two areas, right and left, and juxtaposing in each area (vertically connected) minus-plus-minus-shaped anti-skid parts with a transverse groove at their middle parts together with forming a similar (or minus-plus-minus-shaped), small space in the minus-plus-minus- shaped part neighboring with the anti-skid part. CONSTITUTION:A tire 1 is partitioned into two areas by a longitudinal groove 9. In each partitioned area, minus-plus-minus-shaped anti-skid parts 2, which project to the tread and which is provided with a transverse groove 8 at their middle parts, are juxtaposed. At this time, the anti-skid parts 2 are provided at their respective four corners with projected and rounded parts 4a and 4b, respectively. In addition, a narrow groove 5 is formed between projected parts 4a and 4a neighboring with each other or between projected parts 4b and 4b neighboring with each other. A recessed space 7 is formed between the anti-skid parts 2 and 2, while the space 7 is divided into small spaces 7a and 7b by means of a pleat part 3. With this constitution, a knocking sound, which is produced when the anti-skid parts 2 hit the road surface, turns two types of sounds having the same musical interval in both pitch and intensity at the same time, owing to the presence of similar and small spaces 7a and 7b. As a result, these two types of sounds interfere with each other to be eliminated. With this constitution, the noise level can be lowered.
