Title: Remote test system
Inventor: MORITA TAKASHI
IPC: H04M3/26
Filed: 1979-04-27
Abstract: PURPOSE:To make it possible to transmit and receive test information easily independently of the line type between stations, by using the all confirmation type signal of the sound frequency band to transmit and receive test information between the test machine of the master station and the terminal test machine of the remote station through the channel. CONSTITUTION:When test machine CTE-M' for remote is started by subscriber's line test unit LTE, the CPU of the master station performs outgoing connection. In the remote station side, when incoming trunk ICT is started, incoming connection is performed to connect ICT to the subscriber's terminal where terminal test machine CTE-S' is stored. When CTE-S' responds, the path is closed between CTE-M' and CTE-S'. This path causes sound to pass through independently of the line type between the master station and the remote station, so that the all confirmation type signal of the sound frequency band can be used to transmit and receive information. Further, circuits of the outgoing sender and the incoming sender for all confirmation type signal can be used for the signal receiving part and the expanding circuit of CTE-M' and CTE-S'.

Title: Spatial transmission method
Inventor: MASUMOTO YOSHINORI
IPC: H04B10/118
Filed: 1994-03-23
Abstract: PURPOSE:To provide a spatial transmission method for reducing the mutual interference of signals which are turned to multiple channels and improving communication quality. CONSTITUTION:Plural communication stations 1 to which the channels are allocated transmit the temporary start timing signals of a cycle corresponding to a spreading code series to a centralized control station 3 before starting transmission. The centralized control station 3 receives the temporary start timing signals and returns a difference with a start timing to be allocated to the respective channels to the communication stations 1 as correction signals. The communication stations 1 receive the correction signals and adjust the start timing. Thus, for the transmission from the respective communication stations 1 to the centralized control station 3, synchronization not influenced by the signal propagation state of transmission space is attained, the timing of a part where the mutual correlation value of spreading codes allocated to the respective channels, is lowest is used and the interference among the channels is suppressed.

Title: Method and device for detecting heterogeneous layer in suspension
Inventor: SUZUKI YASUO
IPC: G01N9/28
Filed: 1993-03-12
Abstract: PURPOSE:To make the existence and position of a heterogeneous layer in suspension detectable in an easy manner by measuring the dropped variable of a weight lowered as one body in the suspension and the extent of gas purge pressure in a position in the suspension by means of a gas purge nozzle. CONSTITUTION:A nozzle 3 is dipped in suspension 5 together with a weight 1 and then this nozzle 3 is going down in the suspension as blowing off bubbles of gas 8 from its noze. In this case, while solid portion content in the suspension is almost homogeneous, the extent of purge pressure is proportioned to depth from its level, but if it gets to a heterogeneous layer 6, the purge pressure suddenly goes up, and at a time when it arrives at a sedimentary layer 7, this purge pressure is conspicuously heightened, while the weight 1 is no longer lowered. Here, a distance of the weight 1 lowered is measured (2) by way of rotating a drum with, for example, a wire to lower the weight 1 and thereby integrating the number of pulses to be generated by a servomotor according to this rotation. With this constitution, any variation in the depth direction of the solid portion content in the suspension is easily measurable and, what is more, the existence and position of the heterogeneous layer is thus detectable.
