Title: Equivalent low-order digital filter
Inventor: TSUJIMOTO KUNIYUKI
IPC: H03H17/02
Filed: 1992-01-14
Abstract: PURPOSE:To set output precision to a practical range by filtering control data fetched in a fixed decimal point arithmetic computer in response to a frequency characteristic so as to widen the dynamic range. CONSTITUTION:The filter is used for a fixed decimal point arithmetic computer, which filters control data fetched in the computer in response to the frequency characteristic. That is, the transfer function realized by the digital filter is the same as that of a conventional filter, and as the method to realize the transfer function as above, the transfer function is expanded in a form of (linear filter F(Z)')-(linear filter F(Z)''), where superscripts ', '' in the equation respectively indicate linear and quadratic differential coefficients, and coefficients of the expansion equation are A2-A6. Since a steady-state value of an intermediate variable (alpha) at a feedback summing point is nearly a multiple of 10<3> of an input value X, the output precision of the filter is selected within a practical range. Thus, it is possible to widen the dynamic range of a high-degree digital filter in the fixed decimal point arithmetic computer in this way.

Title: Language processor
Inventor: OKUNO YOSHIMICHI
IPC: G06F17/27
Filed: 1990-01-12
Abstract: PURPOSE:To improve the maintenance properties and to increase the processing speed by providing a hand table where a place contained in an additional function dictionary part is recorded in a place where a morpheme index received from a morpheme processing part is offset. CONSTITUTION:A morpheme processing part 2 accepts an input sentence 1 and analyzes each word of the sentence 1. Then the part 2 recognizes the part of speech of each analyzed word by reference to the contents of a morpheme dictionary part 3 and inputs a part-of-speech index ID signal and a morpheme ID signal to an additional function part 5. This part 5 retrieves the contents of a hand table 7 based on both ID signals and at the same time carries out the designated additional function. In other words, a place contained in an additional function dictionary part 6 is recorded in a place of the table 7 where the morpheme ID is offset. Thus the morpheme ID can be expressed as the offset of the table 7. The part 5 retrieves and reads a searching place of an object dictionary out of the morpheme ID. Thus the maintenance properties can be improved and the processing speed is increased for a language processor.

Filed: 1988-01-14
Abstract: PURPOSE:To simplify wiring and prevent the contact between a substrate and conductor wires by integrally providing multiple insulators on the conductor wire and supporting the conductor wires with the insulators arranged at a proper interval. CONSTITUTION:Multiple conductor wires 1 with insulators are arranged in parallel, the insulators 3a and 3b of the adjacent conductor wires 1 are integrally connected with thin and narrow connecting pieces 4. Both end sections of the conductor wires 1 and 2 are connected with tape-shaped bodies 5 to constitute a conductor wire assembly 6 with insulators windable on a reel as required. According to the above constitution, even if the distance between electrodes to be connected is long, the conductor wires 2 are supported by multiple insulators 3a and 3b at a proper interval, thus the conductor wires 2 are prevented from being deformed and brought into contact with a substrate. In case the conductor wires 2 cross with other conductor wires or the conductor wires 2 can not be linearly wired, the contact between the conductor wires 2 and the substrate can be prevented with the insulators 3a and 3b. As a result wiring is simplified.

Abstract: PROBLEM TO BE SOLVED: To generate a synthesized voice having a more natural intonation than that of a conventional one by providing a coefficient storage means, a pitch control parameter generating means, a pitch control parameter adding means and a pitch generating means. SOLUTION: A coefficient storage means 2 stores coefficients classified by categories classifying characters of accent phrases.

A pitch control parameter adding means 7 adds the pitch control parameter addition value 6 separarely inputted to the parameter 5 and outputs the result as an added pitch control parameter 8. A pitch generating means 9 generates a pitch pattern 10 based on the inputted parameter 8. Thus, the pitch pattern in which a meaningful accent is added as a factor imparting an influence on the pitch control parameter 5 is generated.

Title: Pressure-welded semiconductor device
Inventor: MIYAJIMA TATSUO
IPC: H01L21/58
Filed: 1979-01-19
Abstract: PURPOSE: To prevent the fuse-bonding of metal layers and the deterioration of dielectric srength, by interposing a metal layer of 1600°C or more in melting point between another metal layer and an electrode provided on a diode substrate before pressure-welding an external lead conductor to the electrode through the latter metal layer.  
     CONSTITUTION: A substrate 2 made of molybdenum is fixed on an anode lead conductor 6 made of copper. A diode substrate 1 is bonded on the support plate 2 by a brazing material 3 so that the anode side of the substrate 1 is located face-down. An aluminum electrode 4 is fitted in ohmic contact with the cathode side 1b of the substrate. A cathode lead conductor 7 is pressure-welded to the aluminium electrode through a metal layer 5 of molybdenum, tungsten or the like. In that case, another metal layer 9 of molybdenum, tungsten, vanadium, rhodium, hafnium or the like,  the melting point of which is not lower than 1600°C, is interposed between the electrode 4 and the metal layer 5. As a result, the metal layers 5, 9 are not fuse-bonded  to each other in electrical current supply although their boundary surfaces become  like mirror surfaces because of the difference between their thermal expansion coefficients. Therefore, the dielectric strength does not deteriorate.
