摘要:
A trigger producing circuit provides a trigger signal. A delay circuit receives the trigger signal, and provides a delay signal produced by delaying the trigger signal. A clock counter receives clocks, counts the received clocks for a period from reception of the trigger signal to reception of the delay signal, and provides a result of the counting. A determining circuit stores a relationship between the number of clocks and a latency, and determines the latency corresponding to the result of counting provided from the clock counter. A latency register holds the determined latency. A WAIT control circuit externally provides a WAIT signal based on the latency held in the latency register.

A semiconductor memory device for operating in synchronization with a clock is disclosed. The semiconductor includes a memory array having a plurality of memory cells arranged in rows and columns; and a control circuit performing a control, operation to effect row access processing on a selected row and to effect column access processing on column(s). The control being performed in synchronization with a first clock defined by a time of production of the read signal or the write signal according to an externally applied control signal. the control is also performed in synchronization with a second or later clock defined by a latency, to effect the column access processing on a second number of the columns remaining in the burst mode access

It is an object to provide a method and an apparatus for recovering indium, the method and apparatus ensuring that it is unnecessary to recover indium in the form of indium hydroxide, indium can be recovered easily by a filter or the like without handling inferiors and also, the recovery rate of indium is greatly improved. The method includes immersing a precipitation-inducing metal which includes zinc and is made into the form of a solid such that any part coming into view three-dimensionally has a longitudinal length of 2.5 to 10 mm in an etching waste solution containing at least indium and ferric chloride and allowed to stand, thereby allowing indium contained in the etching waste solution to precipitate on the surface of the precipitation-inducing metal based on a difference in ionization tendency between zinc and indium, and detaching the indium precipitated on the surface of the precipitation-inducing metal to recover it.
摘要:
Two identical images are printed, side by side, on an intermediate transfer-recording medium, by using image data that represents an image to be printed on a brochure. The two images thus printed are compared, thereby to determine whether they have defects. One of the images, which is found to have no defects, is transferred from the intermediate transfer-recording medium to the brochure, which is a final transfer-recording medium.
摘要:
Independent power supply systems are provided for a peripheral circuit other than a column decoder, an array-relevant circuit, and a column decoder respectively, so that a peripheral power supply voltage, an array power supply voltage, and a column decoder power supply voltage generated independently of each other are supplied to the peripheral circuit, the array-relevant circuit, and the column decoder as an operating power supply voltage, respectively. Preferably, the column decoder power supply voltage during normal operation is set as an intermediate voltage between the peripheral power supply voltage and the array power supply voltage. Thus, an array configuration suitable for driving a transistor with a low voltage in order to achieve lower power consumption can be obtained.

Each of first and second program circuits includes a determination node, first to fourth fuses, first to fourth N channel MOS transistors, and first to fourth supply lines. The first to fourth N channel MOS transistors receive first to fourth row address predecode signals, respectively. The first N channel MOS transistor included in the first program circuit and the first N channel MOS transistor included in the second program circuit are arranged adjacent to each other. The first supply line provides a first row address predecode signal to the gate of these two N channel MOS transistors. The same applies for the second to fourth N channel MOS transistors and the second to fourth supply lines. Accordingly, the interconnection capacitance of the row address predecode signal line can be reduced. Also, the size of the transistor driving the row address predecode signal and the transistors in the program circuit can be reduced to allow a smaller layout area for the entire chip.
