Title: Constituting method for dial signal for mobile
Inventor: HATSUTORI TAKESHI
IPC: H04W92/10
Filed: 1980-10-13
Abstract: PURPOSE:To prevent the erroneous receiving of a dial signal due to interference of the same channel, by transmitting a zone discrimination code in advance of transmission of the dial code. CONSTITUTION:A mobile station-side equipment has a zone discrimination code memory 11, a dial code memory 12, and a control device 14. The control device 14 constitutes a 8-bit preamble first and read out next a 64-bit zone discrimination code (k1-K8) indicating its own zone from the memory 11. This code K1-K8 is designated automatically in accordance with a zone which the mobile station belongs to. Next, the control device 14 reads out a dial code, which is designated by a telephone set 13, from the memory 12. The signal formed in this manner is transmitted to the base station through a level converting circuit 15 and a signal transmission terminal 16. In the receiving side, the receiving of the dial code is effective only when a prescribed zone discrimination code and the dial code are received.

Abstract: PROBLEM TO BE SOLVED: To remove nitrogen from waste water effectively and inexpensively by using a compact apparatus by bringing the waste water subjected to biological nitrification treatment into contact with metallic iron in the case where nitrogen is removed by subjecting nitrogen-containing waste water to the biological treatment. SOLUTION: Waste water containing nitrogen such as ammonia and the like is introduced into a biological treatment tank 1.

At a rear stage of the biological treatment tank 1 a denitrification tank 2 is provided so that the nitrite nitrogen and the nitrate nitrogen in an outflow liquid from the biological treatment tank 1 are made to react with iron 3 and are reduced into nitrogen gas and ammonia and is removed. Iron ions produced by reducing the nitrite and nitrate are combined with phosphoric acid ions and are insolubilized to remove phosphorus in the water.  A high nitrogen removal rate can be attained without altering the biological treatment tank 1 by simultaneously employing the biological treatment and denihitrication by use of the iron 3.

IPC: H03K17/687
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To realize a method and a switching circuit selecting a changing state of a couple of terminals with small power consumption. SOLUTION: The switching circuit is made up of terminals 1, 3, a logic circuit 5, input terminals 15, 19, tri-state drivers 27, 31, a passing gate 33 and conductors interconnecting them. The logic circuit 5 senses a current state of the terminals 1, 3 and a new input state of the input terminals 15, 19. When the logic circuit 5 discriminates the state of the terminals 1, 3 to be changed into an opposite state, the logic circuit 5 get through the gate 33 to make the state of the terminals 1, 3 at any level and then closes the gate 33. Then the drives 27, 31 controlled by the logic circuit 5 provide a signal to each terminal. The power in this case is nearly a half of conventional power to change the state of the terminals 1, 3 completely.  When the logic circuit 5 recognizes that the state is not to be switched into the opposite state, the drivers 27, 31 are operated in a standard way to leave the passing gate to get through and to provide signal of a complete charging level to each terminal.
