Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To transmit the same information efficiently from a slave station to plural other slave stations in which not only 1:1 communication but also 1:n communication is attained. SOLUTION: A caller slave station 1 gives a call request including a special number in place of a destination subscriber number to command simultaneous call to plural other slave stations to a master station 2 by using a simultaneous notice request means. The master station 2 recognizes whether or not a call request given from the slave station 1 commands a simultaneous notice by using a simultaneous notice request recognition means. When the simultaneous notice is commanded, the master station 2 informs a fact of a call by simultaneous notice to plural slave stations 1 being command receiving stations and allocates the same idle channel to the slave stations 1 being the command receiving stations and the slave station 1 being the commanding station.  The slave station 1 being the commanding station connects a prescribed terminal equipment registered in advance to the allocated channel by a terminal call connection means after the master station makes notice of the simultaneous notice.

Title: Semiconductor integrated circuit
Inventor: SHIBA YOSHIMI
IPC: G11C11/413
Filed: 1987-10-31
Abstract: PURPOSE:To prevent the malfunction of an input circuit by inserting a capacitor into the front stage of the initial input circuit during a power source noise generating period, and controlling an input voltage. CONSTITUTION:During the period when a noise is generating on a grounding potential (Vss) supplying line, the input edge of an initial input circuit 3 and the Vss supplying line are linked by a capacitor C, and the input signal level of the initial input circuit 3 is controlled according to the potential fluctuation of the Vss supplying line. Consequently, the input signal level is stabilized without being influenced by the power source noise. Further, since the interval between the signal input edge of the input circuit and the Vss supplying line is linked by the capacitor C only during the power source noise generating period, the switching of the level of the input signal is not delayed by the capacitor C. Thus, the malfunction of the input circuit due to the influence of the power source noise can be prevented.

Title: Water quality purification device
Inventor: YOSHIKAWA HIDEO
IPC: C02F3/10
Filed: 1995-09-30
Abstract: PROBLEM TO BE SOLVED: To make it difficult for refuse to be caught and prevent flowing water from being obstructed when water volume is increased by providing a foamed body layer of which amount is sufficient to float a radial stereo- formed body on water onto that formed body. SOLUTION: To form a purification device 1, a radial stereo-formed body 2 which is provided with a connection part only at its center, in which unwoven fiber layer and foamed body layer are extended radially from the center connection part, and the densities of the unwoven fiber layer and foamed body layer are decreased, gradually from the center connection part to its peripheral part is mounted on a supporting device 5 which is fixedly set on a river floor through a connection means 3. Also the foamed body layer amount is sufficient to float the formed body 2 on water. By this, the formed body 2 floats on water and drifts in flowing water about the supporting device 5 while being changed its position by its own buoyancy and resistance given from flowing water.  When a flow velocity of a river is increased temporarily by heavy rain, the formed body 2 is laid down approximately in parallel with the river floor. Thus flowing water will not be obstructed even when water volume is increased.
