Abstract: Circuit arrangement on a bus line (BL) of an integrated circuit for data transmission between data transmitters (DW1,..., DWY) and data receivers (DR1,..., DRX), the bus line (BL) being charged to a particular electrical voltage level during a precharging phase (VPh) and the voltage level of the bus line (BL) being left or recharged within a recharging phase in accordance with the digital information to be transmitted during a data transmission phase. For the accelerated recharging of the bus line (BL), the latter is connected to a trigger circuit which produces an additional accelerated discharging or charging of the bus line when a predetermined trigger level (S) is reached. The bus line (BL) in this arrangement is divided into N part-lines (BLA, BLB,..., BLN), each of which is connected via a switching element (SGA, SGB,..., SBN) to an input of a logic gate (LG), the output of which drives discharge transistors (T1A, T1B,..., T1N) for the rapid recharging of each individual part-line.

Abstract: In this turn-lock fastener for a sports shoe according to the invention, a pull-cable arrangement, which pulls together the shoe- closing flaps, can be wound onto and unwound from a rotary cable pulley. The pull-cable arrangement consists in this connection of a single pull-cable, and a stop element is provided coaxially with the cable pulley and rotatably mounted in such a manner that the cable pulley can only perform a maximum of up to approximately two rotations in one direction of rotation. A particularly space-saving turn-lock fastener is thus produced, with reliable safety as far as overturning of the pulley cable is concerned.

Abstract: PURPOSE:To improve the mechanical strength and bonding strength of an Si chip to a pad by a constitution wherein a bonding wire contains Au and Pt with the predetermined purity and composition and a very small amount of at least one of Be, Ca and Ge with a predetermined content. CONSTITUTION:A bonding wire for a semiconductor device is formed by adding 1-30W/O of high purity Pt with the purity not less than 99.9W/O to high purity Au with the purity not less than 99.99W/O. Then, at least one of Be, Ca and Ge is added to thus obtained Au and Pt by 0.0003-0.05W/O in total amount, as required. By so doing, it becomes possible to obtain the bonding wire superior in the mechanical strength, particularly in the fructure strength at the bonding time, and increase the tensile strength in the state after an Si chip is bonded to a pad. Thus, a diameter of the bonding wire can be reduced to several tens mum to form a very fine wire and the size of the pad can be also reduced.

Abstract: The invention is directed to an ophthalmic lens having a marking and a method of producing the same. The lens is suitable for spectacles and the like. The method includes applying a removable adhering substance to a region of the surface of the lens body so that the peripheral outline of the substance corresponds to the marking to be formed. Then, an anti-reflection coating is applied to the lens body and, at a time thereafter, the adhering substance and the portion of the coating covering the substance is removed thereby causing a recess to be formed in the coating having a peripheral outline defining the marking. The marking formed in this way is practically invisible to a person wearing spectacles equipped with the lens of the invention. On the other hand, the marking is clearly visible when viewed in reflected light.

Abstract: An electrical power supply (10) is provided with a regulation stage (15) which on being supplied at its input with a dc input voltage with a significant ripple component (VS1_OUT), outputs a dc output voltage (VS2_OUT) at a level substantially equal to the dc input voltage value at the troughs of the input ripple component (VT). As a result of this operation, the power dissipated in the stage is minimised. In order to regulate the dc output voltage (VS2_OUT) to be at a particular level, this output voltage is compared to a reference to produce a control signal (S) that is fed back to an upstream regulation stage (14). This upstream stage (14) then serves to vary the level of the trough voltage at the input of the downstream regulation stage (15). <IMAGE>

Abstract: The invention relates to a fluid-cooled mould for the continuous casting of metals, in particular steel, with a shaping wall consisting, in particular, of a metallic material, which is secured on a supporting plate and is provided with connections for a cooling fluid for the purpose of cooling the wall. In order to reduce the weight of the mould suspension, including the oscillation device to be moved and thereby to enable higher oscillation frequencies to be set for the minimum power requirement in the case of fluid-cooled oscillating moulds, it is proposed to secure spring elements (7) on that side of the supporting plate (2) which faces away from the wall (1). The spring elements are secured on one side in a uniformly distributed manner and have a considerably lower stiffness in the casting direction than in the two transverse directions. In addition, the invention proposes that the spring elements (7) extend in a direction transverse to the casting direction, that the opposite ends of the spring elements (7) be secured on a carrier plate (6), that the carrier plate (6) be connected to a fixed base frame (12) and that an oscillation device (16,17) engage on the supporting plate (2).

Abstract: A speech recognition LSI system has a first sampling circuit (24) which samples, at a first frame interval (T1), which is shorter than 1/2fc (fc denotes the cut-off frequency of a low-pass filter in a speech processing section), an A/D conversion output signal in each frequency band of a speech input signal (Vin). Thereafter, the sampled data of a plurality of frames is stored in a digital low-pass filter (25) where is smoothed. Output data which has been smoothed by the digital low-pass filter (25) is then supplied to a second sampling circuit (26) which in turn produces sampled data having a second frame interval (T2), this being longer than 1/2fc. The sampled data sequentially supplied from the second sampling circuit (26) is supplied to a recognition-processing unit (12) to detect the speech segment. The matching degree between data in the detected speech segment and reference pattern data is detected and the recognition result (Vout) for the speech input signal (Vin) is derived out on the based of the magnitude of the similarities detected.
