Abstract: The present invention relates to a method and an apparatus for making shaped parts or objects from thermoformable webs of plastic using a deep-drawing technique. In the multi-staged method, the webs of plastic are introduced into deep-drawing moulds arranged in the manner of a carousel, either during conveying of the deep-drawing mould or during a break in conveying, and are deep-drawn. The deep-drawn article remains fixed to the upperside of the film and is cut to length during continued conveyance. The polymer foam reaction mixture is introduced into the opened deep-drawing mould, which contains at least one closing part for the foaming mould or a foaming cover, and is applied to the rear of the deep-drawn web of plastic. With the mould closed, the foam reaction and/or foaming takes place during continued conveying and the article is later demoulded.

Abstract: In a photographic processing apparatus (10) for immersing and developing an exposed light sensitive material in a developer contained in a developing tank (14), the temperature of the developer is detected and an evaporation amount of the developer corresponding to an elapsed time period is estimated on the basis of the temperature detected. Then, replenishment water is supplied to the developing tank (14) in a quantity based on this estimated amount of evaporation. Consequently, an optimum concentration of the developer in the developing tank can be maintained, thereby preventing a change in the developing characteristics.

Abstract: A resin composition for sealing semiconductors which comprises (a) a modified epoxy resin composed of (i) an epoxy resin having a specific structure or a graft polymer of an epoxy resin having a specific structure and a vinyl polymer and (ii) a silicone polymer in oily state or as particles having an average particle size of not more than 1.0 micron, which are uniformly dispersed in the epoxy resin or the graft polymer, (b) a hardening agent and (c) an inorganic filler, is herein provided. The resin composition for sealing semiconductors exhibits a low thermal expansion coefficient and a low elastic modulus, generates low stress when thermal shock is applied thereto and exhibits high heat resistance during soldering even after moisture absorption. Therefore, if the composition is used to seal large-scale semiconductor devices having high degree of integration or small-sized, thin semiconductors such as flat packages, these semiconductors provide high reliability.

Abstract: In a soldering device with at least one bow-shaped electrode (B1), which can be heated by means of electrical resistance heating, its rectangular working surface (A1) is intended to be capable of being positioned exactly parallel on the solder point which is located, for example, on a printed-circuit board. This is made possible by means of a pivotable suspension of the bow-shaped electrode (B1), the dislocated rotation axis (Da1) of this pivotable suspension having to run in the plane of the working surface (A1), centrally and at right angles to the longer side of the working surface (A1). In consequence, a more secure contact of the parts to be soldered to one another and to the working surface of the soldering bracket (B1) is ensured. In the case of soldering devices having two or four soldering brackets, each individual one of these soldering brackets is pivotably suspended individually.

Abstract: Data bus synchronizer circuit (20) based on the principle that if the phase relationship of a sending bus clock (22) and a receiving bus clock (24) is known at a first point in time, and the frequencies of the two clocks are known and fixed, then the phase relationship can be determined at any time in the future through extrapolation. The circuit has a metastabilization pipe (50), used to remove metastability from the sending bus clock, comprising a plurality of flip-flop circuits connected in series. The clock of the sending bus is input to the first flip-flop of the pipe, and the pipe flip-flop circuits are clocked by the receiving bus clock. Output of this pipe is fed to the input of a serial to parallel conversion circuit (54).  The parallel outputs of the converter are fed to selector circuits (56, 58). The outputs of the selector circuits are fed to an AND gate (62) that creates an enabling signal that is used to enable the transfer.
