Title: Transmission
Inventor: NAKAYAMA HIROSHI
IPC: F16H3/08
Filed: 1988-05-31
Abstract: PURPOSE:To extremely shorten the axial dimension of the above transmission by providing the transmission composed of plural disengaging means arranged between the first and second counter gears and main driven gear meshed with the whole of plural second counter gears. CONSTITUTION:The first output shaft 14a around a main driven gear 14 is arranged in such a way as to be dislocated downward to the input shaft 12 around a main driven gear 13. By thus dislocating both shafts 12, 14a, the degree of freedom in setting respective gear ratios in the route from the main driven gear 13 through the first and second counter gears to the main driven gear 14 is made higher, thereby easily setting the speed change ratio every speed change steps in the transmission 10. In this transmitting mechanism, the first counter gears 21, 31 and 41, 51 (not shown), the second counter gears 22, 32 and 41, 51 (not shown), and hydraulic clutches 23, 33 and 43, 54 (not shown) are arranged in parallel to each other in the faces thereof right to respective shafts. Thus, it is possible to extremely shorten the axial dimension of the transmission.

Title: Signal analyzing device using wavelet conversion
Inventor: NOZAKI ATSUKO
IPC: G06F17/14
Filed: 1995-05-31
Abstract: PURPOSE: To make it easy to select values of parameters of wavelet conversion and accurately extract feature parts of signal data. CONSTITUTION: A sampling means l gathers signal data from a signal source at a specific period. A wavelet converting means 2 performs wavelet conversion based on the input of data from the sampling means 1. At this time, a wavelet variance arithmetic means 4 calculates wavelet variance w(a) on the basis of the value of the wavelet conversion. A wavelet variance evaluating means 5 determines a scale parameter (a) corresponding to the best analytic sensitivity by detecting the peak of the wavelet variance and substitutes it for the parameter that the wavelet converting means 2 currently uses. Then a wavelet variance evaluating means 5 allows the wavelet converting means 2 to output it to a signal analyzing means 3.

Abstract: PURPOSE:To provide a heat transfer tube of a high thermal efficiency which is easy to manufacture by closely fixing a cylindrical body formed by turning thin plates each having a winding diameter substantially the same as the inner diameter of a tubular body provided at its one surface or both surfaces with a large number of depressions or through holes, to the inner surface of a tubular body having a smooth inner surface or a grooved inner surface. CONSTITUTION:A cylindrical body 2 is formed by thin plates each of which has an increased surface area of one surface or both surfaces as thin plates 3, 4, 5 and 6 and also has an outer diameter dimension substantially the same as the inner diameter of a tubular body 1. The thus formed cylindrical body 2 is turned around a core rod having a diameter which is slightly larger than the inner diameter of the tubular body 1. The cylindrical body 2 is inserted into the tubular body 1 together with the core rod, and then the fixing of both ends of the thin plate is released. The winding diameter of the cylindrical body 2 is expanded by an elastic reinstating force of the thin plate, and the winding force with respect to the core rod is loosened. Thus, the core rod can be drawn out of the tubular body 1 and can also be closely fixed to the inner surface 1a of the tubular body 1. Further, the core rod can be positively secured thereto by the method of extracting the tubular body 1 and the roll pressing method. The heat transfer efficiency is improved by the increase in the area of the front surface within the tubular body 1, generation of the turbulent flow and occurrence of the capillary tube phenomenon.

Filed: 1990-05-28
Abstract: PURPOSE:To precisely estimate context structure as against a long sentence having complicated context structure before the syntax analysis and the semantic analysis by holding context structure instruction information existing among more than three context structure instruction expressions in a context form holding mechanism. CONSTITUTION:The appearing patterns of the context structure instruction expressions, a possible modification relation between words in the patterns, an appearing frequency and a restriction condition as against the modification relation, and a condition as against modification among various patterns are described in the context form holding mechanism 5 in a context analysis part 4.

Furthermore, a context structure estimation mechanism 7 estimates context structure which is most certain among the received candidates of context structure and transmits it to a syntax analysis part 8. Thus, context structure is precisely estimated.

Abstract: PURPOSE:To obtain a building board superior in strength and dimensional stability, etc., without using asbestos having an environmental problem by mixing cement, silica (containing) powder, woody fiber, wollastonite and a dispersant, making sheet and hardening. CONSTITUTION:Cement (e.g. Portland cement), silica powder or/and silica- containing powder, woody fiber, wollastonite and the dispersant (e.g. polyoxyethylene alkylether) are mived and the mixed product is dispersed in water to make a slurry. Next, the obtained slurry is manufactured to sheet by a normal method and the manufactured sheet is pressed to dehydrate and is hardened by a primary aging and a second aging to produce the building board. Thus, since a portion of the woody fiber is replaced with wollastonite, as reinforcing fiber of a hardened body comprising mainly primary cement and silica, the dimensional stability and crack resistance which are defects of the woody fiber, are improved.
