Abstract: When successive DMA transfer is to be performed between a plurality of areas of a memory and a DVD decoder, pairs of start memory addresses and transfer counter values corresponding to the plurality of areas are respectively set in a plurality of DMA register sets. The contents of these DMA register sets are sequentially read in a predetermined order, and a plurality of DMA data transfer operations are repeatedly executed by a DMA controller. Immediately after one DMA data transfer is completed, next DMA data transfer starts in accordance with the contents of the next DMA register set. Successive DMA data transfer can be executed continuously.

Abstract: Naphthyridine derivative of the formula: ##STR1## wherein Ring A is substituted or unsubstituted pyridine, X is --N(R.sup.2)--CO--(R.sup.2 is H, alkyl, substituted alkyl, etc.), Z is a direct bond, --NH--, C.sub.1 -C.sub.2 alkylene, or --CH.dbd.CH--, Y is alkyl, substituted alkyl, aromatic group or substituted aromatic group, etc., B is alkyl, substituted alkyl, aromatic group or substituted aromatic group, or an acid addition salt thereof, these compounds having acyl-CoA: cholesterol acyl transferase inhibitory activity, and being useful as an agent for prophylaxis or treatment of hyperlipidemia, atherosclerosis, and related diseases thereof.

Abstract: Prefilled syringe for injection of two liquids includes a syringe body with an injection port at a closed end thereof, first and second gaskets fluid-tightly fitted into the syringe body to separate two medical solutions filled therein, and a closing member for closing the injection port. The syringe body is provided with bypassing grooves extending in the longitudinal direction of the syringe from a position adjacent to the closed end thereof. Liquid communication means is provided between the closed end and the first gasket. By pushing a plunger, the first and second gaskets are forced to move forward so that two medical solutions are injected one after another.

Abstract: An initial synchronization system for spread spectrum communication including a despreader-demodulator circuit for despreading and demodulating an input signal according to a despread control signal, a decoder circuit for decoding a data signal demodulated by the despreader-demodulator circuit and outputting a code synchronization signal when code synchronization is taken, a correlation detector circuit in response to the input signal for detecting the correlation of the input signal and generating the despread control signal and a correlation detection signal, and a control circuit for outputting an initial synchronization start signal to the correlation detector circuit so as to cause the correlation detector circuit to start the initial synchronization if the code synchronization signal is not generated within a predetermined period after the correlation detection signal was generated.

Abstract: A heat-resisting spheroidal graphite cast iron comprises carbon ranging from 1.8 to 3.4% by weight, silicon ranging from 3.5 to 6% by weight, manganese ranging from 0.7 to 1.25% by weight, chromium ranging from 3 to 5% by weight, nickel ranging from 18 to 24% by weight, an element for spheroidizing graphite, not more than 0.1% by weight, and the balance being substantially iron, thereby attaining excellent oxidation-resistance and oxide film adherance characteristics while being kept inexpensive.
