Abstract: A block access system using a cache memory comprises a first control circuit (12) for producing a block access request for requesting read-out of all data included in a block of a predetermined size in response to an access request from an operation unit (10) and inputting the data read out from a main memory unit (16) into a cache memory (13), and a second control circuit (15) for reading out data from the main memory unit and sending back to the first control circuit a response signal ( BLACK ) which indicates any one of execution and cancellation of the requested block access in response to a block access request ( BLOCK ) from the first control means. Memory addresses necessary for reading out all the data in one block are produced by the first control circuit when the block access request is cancelled. Alternatively, memory addresses are supplied by the second control circuit when the block access request is executed.

The device uncludes a case (1) and an IC card (9) as an external storage unit detachably attached to the case(1). A plurality of digitized sound data groups are stored at a built-in memory (10) of the IC card (9). The digitized sound data groups are obtained by recording sentences for foreign language conversation practice through a microphone to thereby obtain analog sound signal which is converted to digital sound signal. When the IC card (9) is attached to the case, a signal processing circuit (15) operates to read out the digital sound data group, which is converted to the analog sound signal. The analog sound signal is supplied to an amplifying circuit (17) and reproduced as sound from an earphone (8).

Abstract: Oligomeric carbonate dihydroxyaromatic-based chainstoppers are disclosed. One example of this type of chainstopper is a bisphenol A bischloroformate oligomer monocapped with phenol. These chainstoppers may be prepared by phosgenating a dihydroxyaromatic compound to terminate one or both of the terminal oxygen atoms with chlorocarbonyl groups, followed by reaction of the chlorocarbonyl-terminated material with a phenolic-type compound in the presence of an amine catalyst. The chainstoppers of the present invention are very useful in accurately controlling the molecular weight of polycarbonates formed by various processes, while also preventing the formation of undesirable by-products, such as diarylcarbonates.

Abstract: Die Konzentration der Innenstörstellen in einer Halbleiter­scheibe wird in einem zweistufigen Wärmeverfahren gesteu­ert. In einer Konzentrationsreduktionsphase wird die Scheibe schnell auf eine erhöhte Temperatur im Bereich von ungefähr 900 bis 1350° C erwärmt, was zu einer teilweisen oder gesamten Auflösung von ausscheidbaren Verunreinigungen in der Scheibe führt. In einer Konzentrationssteigerungs­stufe werden die Scheiben einem Temperverfahren bei relativ niedriger Temperatur, bei dem die Dichte der potentiellen Innenstörstellen erhöht wird, unterworfen. 
Durch entsprechendes Steuern der Verfahrenstemperaturen und Behandlungszeiten können die zwei Stufen in jeder Reihen­folge durchgeführt werden, um Scheiben zu erhalten, die Innenstörstellenkonzentrationen innerhalb eines gewünschten Bereichs aufweisen.

Abstract: The invention provides a process for spinning segmented polyurethane-urea elastomers into dry spinning cells by introducing certain amounts of superheated steam. The process makes possible a remarkable increase in the productivity per cell and also in the spin speed, in particular in the case of medium and high deniers, at high spinning cell temperatures and without undesirable alteration, in fact in some instances with distinct improvement, in the properties of the knitting filament yarns. The novel process more particularly also prevents decomposition tendencies of the spinning solvent at high temperatures (otherwise necessary for substantial spinning solvent removal at high spinning speeds) in air without having to use inert gases as spinning atmosphere. The novel process further makes it possible to produce (multi)filament yarns having higher filament linear densities, which helps to improve the stability of the filament yarns to external influences and degradation effects.
