IPC: G06F1/32
Filed: 1987-01-08
Abstract: PURPOSE:To reduce an unnecessary current consumption by controlling supply of a supply voltage to a function block by a voltage supply control means which supplies or stops the supply voltage to the function block in accordance with the control signal from a central processing unit to the function block. CONSTITUTION:When a CPU 1 uses a communication block 2, a status STASO of the communication block 2 is read out from a bus buffer 49 of a voltage supply control circuit 4 for the purpose of confirming the status of the block 2. In the case of the start of the use, a connection/disconnection signal IOBLO to the communication block 2 is outputted to a control circuit 4 to supply a supply voltage Vcc through a flip flop 41, a buffer 43, and a transistor TR 47.

Title: Atm switchboard
Inventor: HATONO ATSUO
IPC: H04Q3/00
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain an asynchronous transfer mode(ATM) switchboard capable of reducing a call loss ratio in connection reception control under complete priority control and improving a line utilization ratio. SOLUTION: When a connection setting request is outputted from a terminal, the ATM switchboard calculates the cell loss ratio of each priority class by a step 330. The cell loss ratio is approximately calculated as a synergetic effect between a cell overflow ratio from a line which is calculated from a parameter related to a cell arrival ratio and line capacity in a step 310 and a cell loss ratio reducing effect by a buffer which is calculated by using a parameter related to burst length and the buffer length of respective priority classes in steps 322, 323. When the cell loss ratio is more than an allowable cell loss ratio, a connection setting request from a terminal is controlled so as not to be received.

Title: Logic integrated circuit
Inventor: MIKOSHIBA KEIMEI
IPC: H03K19/018
Filed: 1987-01-09
Abstract: PURPOSE:To obtain a very large-scale integrated circuit whose operating current is 100muA or lower and degree of integration is 100000, by using an ECL circuit of minute bipolar transistors TRs in case of a light load and adding a buffer of complementary bipolar TRs in case of a heavy load with respect to a logic gate. CONSTITUTION:When a current I0 of a constant current source 3 is set to 10muA and a load Rc is set to 50kOMEGA for a one-stage inverter consisting of minute npn TRs 1 and 2 whose dimensions are 10mum<2>, the delay time is about 100ps. If complementary bipolar TRS 6 and 7 are added and voltages between bases and emitters are kept proper, the steady current can be ignored. When the constant current I0 is set to 100muA and the load Rc is set to 5kOMEGA and RL is set to 0.5PF, the delay time is 150ps and the power consumption is 0.33mW. Thus, the power consumption is reduced to 1/10 and the speed is equivalent in comparison with a conventional ECL gate, and the very-large-scale integrated circuit of 100000 gates is realized.

Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent transmission of fluid and improve sealing capability by covering the surface of a ring-shaped core body made of a resin material with a thin coating layer made of a rubber material. SOLUTION: A seal ring 1 is the one in which a coating layer 3 of a rubber material is integrally formed on the surface of a ring-shaped core body 2 made of a resin material. As the core body 2, fluororesin, in particular, is suitable and the cross section of a resin material is formed into a cylindrical shape and the plane is formed into a ring-shape by a molding machine for a compression molding, an injection molding and a transfer molding. On the surface of the core body 2, the coating layer 3 is integrally burned and molded. Small recessed and projecting parts are formed on the surface of the core body 2 or a plurality of small grooves are formed along the peripheral direction, the recessed and projecting parts and the grooves are molded integrally with the coating layer 3, and adhesive strength force with the coating layer 3 is made excellent.  As the coating layer 3, fluorine-contained rubber, NBR, silicon rubber are suitable. In particular, fluoroelastomer as a material sealing corrosive fluid is suitable for the coating layer 3. Therefore, because swelling due to liquid can be prevented and the core body 2 does not transmit both of gas and liquid to be sealed, the core body 2 is excellent in interruption capability of working fluid.
