Title: Method for processing digital voice signal
Inventor: OGURA YASUHIRO
IPC: G11B20/10
Filed: 1994-01-24
Abstract: PURPOSE:To transmit a digital voice signal by fully making the most of the number of bits. CONSTITUTION:A signal from an input terminal 1 is supplied to a quantizer 3 through an adder 2, for example, converted to 16 bits and taken out to an output terminal 4. Signals before and after of this quantizer 3 are supplied to a subtracter 5. An error signal taken out by this subtracter 5 is supplied to a filter 6, a signal passed through the filter 6 is supplied to the adder 2. At the same time, a signal from the input terminal 1 is supplied to a dynamic range detector 7, a dynamic range of an inputted digital voice signal is detected by a detector 7. That is, this dynamic range corresponds to word length of data of the digital voice signal, the dynamic range is detected by measuring word length of this data. Or it can be done by setting a switch and the like. Thus, a frequency characteristic of the filter 6 is changed in accordance with this detected dynamic range (recorded bit numbers).

Title: Production of fused flux for submerged arc welding
Inventor: KONISHI TOSHIO
IPC: B23K35/40
Filed: 1981-01-17
Abstract: PURPOSE:To remove iron content and phosphorus content in ore and to obtain a fused flux of high performance for submerged arc welding by melting a raw material consisting of manganese oxide ore as a containing component and adding wood of an excess amt. with respect to the amt. of oxygen in the compounded raw material as a reducing agent. CONSTITUTION:A flux raw material contg. a low grade of manganese oxide ore contg. >=3wt% iron oxide in terms of Fe and >=0.06% phosphorus oxide in terms of P are melted. Wood of >=1.5 times the amt. of oxygen in the raw material is added to this as a reducing agent and the iron content and phosphorus content contained in the ore are reduced away. The amt. of oxygen in the raw material is calculated by the following equation. Amt. of oxygen =0.2227X(amt. in terms of FeO in the compounded raw material)+0.5636X(amt. of P2O5) in the raw material)+0.0699X(amt. of Mn3O4 in the raw material). By this method, the impurities in the compounded raw material are removed efficiently and the fused flux for submerged arc welding of high quality is produced from raw materials of a low grade.

Title: Heat radiating device for functional element of electronic equipment
Inventor: MUTSUKAWA HIROYUKI
IPC: F28D15/02
Filed: 1990-01-17
Abstract: PURPOSE:To radiate the heat produced by a functional element more efficiently in a stable state by providing radiation fins to the outer surface of the cavity section of a sealed container. CONSTITUTION:The heat produced by a semiconductor element 2 is absorbed by the working liquid 4 in a liquid reservoir 3a adjacent to the element 2 and the vapor of the liquid 4 produced by the heat of the element 2 moves upward and reaches a cavity section 3b. After reaching the cavity 3b, the vapor further moves toward the end of the cavity 3b along the upper surface of the cavity 3b. While the vapor move in such way, the heat of the vapor is removed by radiation fins 5 and the vapor is condensed to the liquid which returns to the liquid reservoir 3a along the lower surface of the cavity 36. As the internal heat movement by the vaporization and liquefaction of the working liquid 4 continues, the semiconductor element 2 which is the heat source is effectively cooled. Therefore, the heat of a functional element can be radiated to the outside effectively and stably and the reliability, etc., of the element can be improved.

Title: Control device for elevator
Inventor: TETSUYA YUJI
IPC: H02P23/16
Filed: 1994-01-25
Abstract: PURPOSE:To shorten a regulating time of a torque bias amount of control of an elevator. CONSTITUTION:An elevator 9 coupled to a motor 6 through a transmission 8 is controlled through control of the number of revolutions of a motor 6 through a control device 14. When, by adding a torque bias amount tauBIAS to the output of a speed regulator 2, a delay in a replay of the speed regulator 2 is compensated, a long time is taken because of a gain K1 being heretofore set as monitoring is effected by an operator. Thereby, by mounting a computer 16 to automatically compute the gain K1 from a torque command average value and a detecting signal from a load detector 11, a torque bias amount is determined in a short time.

Abstract: PROBLEM TO BE SOLVED: To enable prize balls to be smoothly transferred. SOLUTION: A discharging device comprises a drum 45 having a plurality of ball receiving parts 49 along the outer periphery of the drum 45. When a number of prize balls are lined on a rail 41, since pressure toward the drum 45 is strongly applied to the prize balls near the drum 45, a prize ball Ba is led to the ball receiving part 49 at the ball receiving position and a prize ball Bb is also entering the ball receiving part 49 which reaches the ball receiving position next time. In this instance, the prize ball Bb is brought into contact with the rear side of a tip 60b, like an arrowhead, of a regulating member 60. Then, the regulating member 60 turns counterclockwise, the belly side is come into contact with the cylindrical member, and the rear side of the tip 60b regulates the prize ball Bb so as not to enter the ball receiving part 49 which reaches the ball receiving part next.  Consequently, the drum 45 can rotate without being stopped and the prize balls can be smoothly sent.

IPC: H01R4/70
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To easily find a fixing state and prevent the coming off of an electric wire, even if bending force is applied. SOLUTION: A bowl-shaped cover main body 10 for covering a terminal metal fixture T is made of hard resin, and a locking piece 12 to be locked to a receiving part R on an appliance K side is formed in the cover main body 10. An electric wire cover 20 covering an electric wire W is connected, capable of relatively displacing to the cover main body 10 by the pivoting structure of a supporting shaft (a connecting means) and a bearing hole (a connecting means).

Abstract: PURPOSE:To provide a luminous display body where a mark is distinctly seen from a position on the outside of the range where light emission should be controlled by providing light reflection layers, which are placed on the inside of a display layer, on end faces as both sides of a prism. CONSTITUTION:A display body main body 1 provided with a prism 1a as one body, a light diffusing plate 5 arranged on the rear side of the prism 1a, and a light source 6 provided on the rear side of the light diffusing plate 5 are provided.
