摘要:
An evaporator comprising a plurality of heat transfer fins arranged mutually parallelly relative to the direction of air current and a multiplicity of louver boards formed by cuts inserted in substrates of said heat transfer fins perpendicularly to the direction of air current and sloped to prescribed angles from said substrates so as to be divided into a plurality of louver groups by the direction of sloping, which evaporator has the louver at the downstream zone of the fins in the direction of air current sloped so that the flow of the water condensate by gravity directs to the direction of an interior of the evaporator.
摘要:
The number of response-waiting requests which are already sent to a server (4) but to which a response is not yet returned from the server (4) is limited. To limit this number, received requests are temporarily accumulated in a buffer if the number of response-waiting requests has reached a threshold and, until the number of response-waiting requests falls below the threshold, requests are not sent from the buffer. The execution status of the server (4) is monitored, and the threshold is increased when the response time from the server (4) to a request is within an allowable range, and the threshold is decreased when the response time exceeds the allowable range. In addition, TCP connections between a load control device (3) and clients (1-1, . . . , 1-n) are aggregated so that the number of simultaneous connections of TCP connections between the server (4) and the load control device (3) becomes equal to or smaller than the threshold of the number of response-waiting requests.
摘要:
The tunable optical filter comprises a pair of optical switches and an arrayed-waveguide grating router that has sixteen input waveguides and sixteen output waveguides. The frequency-division-multiplexed optical signal is directed through the first 1.times.4 optical switch to a selected input waveguide of the router so as to be demultiplexed into output waveguides of the router. The second 1.times.4 optical switch selects one of four output waveguides of the router so as to obtain a selected optical frequency. By appropriately connecting the switches with the input and output waveguides of the router, sixteen combinations of switch states correspond respectively to sixteen frequencies to be passed by the tunable optical filter. As a result, the filter can be tuned digitally to one of sixteen frequencies with small-size (1.times.4) optical switches. It is also possible to reduce the loss in the tunable optical filter because the optical signal is only required to make a single passage through the arrayed-waveguide grating router.

摘要:
A sand pile driving method for making a sand pile which does not cause trouble in terms of strength even at a soft point in the actual ground, and enables secure limitation of the increase in total construction time and total amount of sand. A compaction procedure is a procedure for compacting a granule pile 15 by pressing and rotating the casing pipe 13 downward. This is performed based on thrust force P by which the casing pipe presses a granule pile and a driving torque T for rotating the casing pipe against a granule pile.

An optical cross-connect system which can be constructed using the same kind of optical switches having a small extinction ratio and a small number of optical switch driving circuits is provided. The optical signal selector in the system comprises a first optical switching device for permitting only the wavelength-division multiplexed light beam passing through one of plural optical paths to pass, a wavelength router for demultiplexing the permitted multiplexed light beam into optical signals of different wavelengths and respectively outputting these demultiplexed signals into different output ports, this router having a routing characteristic such that the output port to which each demultiplexed signal is output is different for each input port, a second optical switching device for permitting only one of the optical signals output from plural optical paths connected to the output ports of the wavelength router to pass, and an optical combiner for combining the optical paths of the second optical switching device.
摘要:
The present invention provides a signal block sequence processing method. According to the method, signal block headers (Bch, Bdh) are deleted from each sequence of signal blocks (B) each composed of the signal block header indicating whether a signal block payload is a control block payload (Bc′) containing a control code is contained or a data block payload (Bd′) containing data is contained. The resultant signal blocks are formed into one group (G). Each control block payload in the group is provided with position determination information indicating the position of the control block payload in the group. The signal block payloads are rearranged in accordance with a signal block payload rearrangement rule. The rearranged signal block payloads are contained in a super-block payload (Sc), to which a super-block header (Shc) indicative of containment of control block payloads is added. The resultant super-block (S) is output.
摘要:
A method for predicting reactivity to parathyroid hormone by determining the genotype with respect to polymorphism in the parathyroid hormone receptor gene. The results obtained by the analysis of genetic polymophism are useful for predicting the tendency for a hemodialyzed patient to develop severe secondary hyperparathyroidism, or for predicting the tendency for a human individual to develop severe primary hyperparathyroidism. Also, this method is useful for predicting the therapeutic effects by predicting reactivity to parathyroid hormone in a patient who is being treated for regressive osteoporosis by administration of parathyroid hormone.
