Abstract: PURPOSE:To detect a voice segment with high precision without being adversely affected by the change rate of a crest value by computing voice signal starting and stopping positions, which are buried in the noises, from inputted voice signals. CONSTITUTION:A first comparator 5 detects a position K1 at which the crest value of the input signals from a voice amplifying circuit 2 exceeds the signal level that is obtained by averaging the noise pattern from a noise recognition means 10 in an averaging circuit 12 and the input voice detection signals are transmitted to a waveform predicting circuit 13 and a noise pattern editing circuit 10a. The circuit 10a discriminates the voice signals, which are inputted prior to the input voice detection signals, as noises and a noise pattern memory 10b keeps the discriminated noise level. A region detecting circuit 10c, which discriminates the inputted voice signals become less than the noise level, detects that the input signals are reduced. The detection signal is checked whether the signal lasts longer than a prescribed time or not and if it lasts longer than the prescribed time, the circuit 10c outputs a voice input completion signal.

Abstract: B-Adjacent coding is used to correct up to two DASDs in error in an array of N data DASDs and two redundant DASDs. When two of the data DASDs fail, their data can be recreated as a function of a pair of syndromes constituting up to two Boolean equations in two unknowns. Prestoring of the matrices of the powers of the polynomial terms of the code primitive together with pipeline processing operate to expedite data recovery and balance the write operations load on the DASDs across the array. Recovery from the failure of a data and a redundant DASD involves resolving one linear Boolean equation with one unknown.

Abstract: A method for the topically precise subsequent-engraving of printing cylinders wherein special marks are engraved in the cylinder and evaluated. The marks are engraved in the form of cups forming a cup track. The cups serve as reference marks for an axial feed and start of the subsequent-engraving in a circumferential direction. After the printing cylinder has been mounted in an engraving machine for subsequent-engraving, the cylinder is placed in rotation and the scanner is moved over the previously engraved cup track axially. A maximum of the signals received from the scanner is identified and a location of the maximum in the cup track is retained as a reference value for the axial feed during the following engraving. A cup track is provided with at least one defined gap that is free of cups. A first cup following the gap is identified by means of the scanner and evaluated as a reference location for a start of engraving in the circumferential direction for the following subsequent-engraving.

Abstract: PURPOSE:To reduce the actual mounting area to enable high density packing by mounting semiconductor chips on a substrate and then connecting these chips by a wire bonding method or the like. CONSTITUTION:An apperture A is provided on a substrate 11, an electrode 14 on a semiconductor element 13 is fixed in a position corresponding to the aperture A, and the electrode 14 is connected with a wiring pattern 12 using a metal line through the aperture A. Thereby, the region connecting the meal line can be reduced remarkably, enabling connection in minute pitch. Moreover, since it is possible to mount other elements, for example, small-size semiconductor element or chip parts, mounting density can also be enhanced remarkably and wiring length can be shortened. This feature is just suitable for high speed transmission of signals and bonding of heat sink to the semiconductor element is also very easy. Accordingly, a semiconductor element which shows a large power consumption can be mounted.

Abstract: The present invention relates to a heat-insulating multiple glazing and a vacuum multiple glazing. Conventionally, this type of glass does not provide sufficient heat-insulating performance. And, it has been necessary to form the heat-insulating multiple glazing thick, in order to enhance the heat-insulating performance. The present invention comprises a first vacuum multiple glazing (2) including two sheet glasses (3), (4) having peripheries thereof sealed and a plurality of layers of spacer (5) disposed within a gap therebetween, with the gap being depressurized; and a second vacuum multiple glazing (2) or an ordinary sheet glass (10) overlapped with the first multiple glazing (2) with a gap relative thereto and having the periphery thereof sealed with a sealing material (12), with the gap being charged with dry air or rare gas. Thus, it is possible to enhance the heat-insulating performance, without increasing the thickness of the entire heat-insulating multiple glazing. <IMAGE>

Abstract: The spare disk unit existing in the port other than the parity group to which a failure disk unit in a disk array belongs is most preferentially selected as an alternative destination and data is reconstructed. When a system is made operative, the spare disk unit is allocated to a different port position every rank and the spare disk unit belonging to the rank of the failure disk unit is most preferentially selected as an alternative destination. Due to this, the selection of the alternative destination by the spare disk unit is optimized and the deterioration of performance in data reconstruction is prevented.

Abstract: A composition which comprises (a) a salt of monovalent metal (M) of a carboxylic acid in which the COOH group is attached to a ring atom of a fused ring system and (b) a grease which is a non-soap thickened oil which may be a mineral oil or a synthetic oil such as a silicone oil. The metal (M) may be sodium. The fused ring system is preferably a fused aromatic hydrocarbon ring system such as naphthalene and may include further substituents, for example an -OH group, in addition to the COOH group. If the acid contains both OH and COOH groups, these can be attached to adjacent atoms of the fused ring system. Sodium 2-naphthoate and sodium 3-hydroxy-2-naphthoate have been found to be particularly suitable. The grease has improved corrosion resistance and the addition of the metal compound does not result in destructing of the grease.

Abstract: In a hot runner channel construction set (1) for a stack mould, having needle valve nozzles (2) directed to opposite sides and in alignment with each other, the plungers (4) for driving the respective valve needles (3) are arranged coaxially to the latter in the hot-runner manifold, which for its part is divided into individual blocks (7), of which in each case one individual block (7) is assigned to one needle valve nozzle (2). In this arrangement, a main hot-runner manifold (6) protrudes into the region of the individual blocks (7) and its outlet openings (8) coincide, in the position for use, with the inlet openings (10) of the individual blocks (7), so that, in spite of the division of the hot-runner manifold, there is a continuous way through for the injection moulding material to the needle valve nozzles. The arrangement of the drive plungers in individual blocks of the hot-runner distributor have the overall effect of a small overall height and, after separation of the construction set, a good accessibility to all these individual parts, so that they are well able to be assembled and disassembled.
