Abstract: A method of controlling a clock, including the steps of (a) receiving an external clock signal, (b) calculating a first period of time defined as (T1-T2) wherein T1 is a cycle of the external clock signal, and T2 is a period of time during which the external clock signal is transmitted through devices generating skew to the external clock signal, (c) stopping the external clock signal to be transmitted by the first period of time, and (d) driving the external clock signal to thereby turn the external clock signal into an internal clock signal. The method makes it possible to detect delay in a clock signal, and generate no delay error inherent to a digital circuit.

Abstract: Device for emission-reception of a stream of electromagnetic waves, in which an emission unit (1) and a reception unit (2) are each supplied with light energy passing through an optical guide (13). This light may be stopped by an optical gate (19). Otherwise, it reaches a micro-laser (4) that illuminates a photo-conducting sheet (5) on which an antenna (3) is located. The portions (6, 7) of the emitter antenna (3) at different potentials are then short circuited and a stream of electromagnetic waves is emitted. The wave stream passes through a medium to be studied and is returned to the receiving unit (2) in which it is sampled, recorded and analyzed to determine the composition of the medium through which it had passed. The wave stream has a wide frequency band and the opto-electronic device can be used to make a very compact system.

Abstract: According to a waste water treatment method and apparatus of the present invention, a permeable sheet 3 is fed into a treatment tank 2 in which a stream is formed. The waste water, which flows downstream, is caused to pass through the permeable sheet 3, while the permeable sheet 3 travels in the treatment tank 2 so as to traverse the surface of the waste water on a downstream side in the flowing direction of the waste water. Therefore, not only the sludge in the waste water but also the oily substances floating in the waste water can be collected and removed because they cling to the permeable sheet 3 and are gathered by it. As a result, a waste water treatment tank 2 and the like can be maintained in a usable state for a long time. In addition, there can be obtained a treated water to which microbial treatment can be applied.
