摘要:
A clock synchronous circuit is stopped or started in accordance with the situation. More specifically, the clock synchronous circuit is stopped when no synchronous clock is necessary or in modes, such as a standby mode, bank active mode, refresh mode, and write mode, other than a read mode. In the read mode, the clock synchronous circuit is operated because a synchronous clock is necessary to output data. In the read mode, the number of clocks, i.e., CL, required from the time a read command is input to the time data is actually output, is 3 or more, when restarting and preamble of the clock synchronous circuit are taken into consideration.

A front center opening can be opened and closed by a zip fastener. A hook assembly joins upper ends of the front center opening in a separable way and adjusts a waist size of pants within a fixed range. An adjusting cloth is sewed between one of fastener tapes of the zip fastener and an outer cloth of the front center opening. The adjusting cloth has an overlap to provide an extra length on the waist size of the pants. The hook assembly adjusts the waist size of the pants so as to fit a waist size of a user. The overlap of the adjusting cloth is extended in a specified manner so as to adjust a size of the pants corresponding to a portion lower than the waist of the user.

A data reproduction apparatus for character multiplexing video signal includes an A/D converter circuit for converting a character multiplexing video signal into a digital video signal, an FC detecting/clock generating circuit for detecting an FC signal contained in the digital video signal to generate a clock signal for character data reproduction, a delay circuit for delaying the digital video signal by a period of time corresponding to time required for the FC detecting/clock generating circuit to generate the clock signal, and a data reproducing circuit for reproducing character data by sampling the digital video signal which is time-adjusted by the delay circuit by use of the clock signal.

An 8-bit CLA adder is constructed for inputting 4 lower bits a3:0,b3:0 and 4 upper bits a7:4,b7:4 of two input signals to the two 4-bit full adders 2,12 and a carry c-1 to the lowest bit the full adder of the first-stage 2 to generate carries c3,c7 correspondint to the third and seventh bit of the input signals from a carry generation signal g7:0 and a carry propagation signal p7:0 generated by the both adders 2,12 and the carry c-1. The full adder of the second-stage 12 is constructed to add the 4 upper bits a7:4,b7:4 with setting a carry-in as 0 so as to generate a temporary summing signal sz7:4. A logical circuit 14 generates a true sum of 4 upper bits from a carry c3 to the third bit to the forth bit, a temporary sum sz7:4 and a carry propagation signal p7:4 generated by the full adder of the second-stage 12.

The present invention provides a traverser, which includes a support member driven by a chain and movable between a carry-in rail and carry-out rail which are disposed parallel with each other. The support member transfers a truck from said carry-in rail to said carry-out rail. A groove for receiving a flange of a wheel of the truck is formed in an upper surface of the support member.

An electrophotographic charger of the type in which a plurality of corona wires extend in the axial direction adjacent to and separated from the surface of a photosensitive drum in order to charge the surface. A plate-like etching grid is interposed between the corona wires and the drum to ensure the charge is uniformly placed on the drum. The grid is divided into a number of individual removable grids so that the distance between each grid and the adjacent corona wire, and the distance between each grid and the drum surface is substantially uniform.

A process for producing triterpene alcohol, comprising sequentially conducting the following steps (A) to (C): (A) subjecting γ-oryzanol to alkaline hydrolysis; (B) mixing the alkaline hydrolysate with a low polarity organic solvent, and extracting triterpene alcohol to obtain a triterpene alcohol-containing low polarity organic solvent; and (C) adding water to the triterpene alcohol-containing low polarity organic solvent thus obtained, removing the low polarity organic solvent, and then melting triterpene alcohol in hot water, followed by cooling.
