Title: Master slice lsi
Inventor: KOMOTA MICHIO
IPC: H01L21/822
Filed: 1991-03-12
Abstract: PURPOSE:To enable an unneeded power consumption to be reduced by providing a switching element between a cell of a master slice LSI and a power supply which drives it. CONSTITUTION:When an input port 1a is at a logic level 0, a logic operation of a block circuit 5 consumes an unneeded power since a logic level of an output port 2 is at the logic level 0. Therefore, when an input port 1a is at the logic level 0, switch elements 7a-7c are turned off by a control circuit 9, the circuit block 5 is turned into non-operation state, thus enabling power which is consumed by the block 5 to be reduced. At this time, a pull-down element 8 is provided to prevent one input terminal 6 of a cell 3d from becoming a logic level 'undefined'. When the input port 1a is at a logic level 1, the logic level of the output port 2 is determined by the logic of the circuit block 5, thus allowing the control circuit 9 to turn on switch elements 7a-7c an the circuit block 5 in operation state.

Filed: 1986-03-04
Abstract: PURPOSE:To reliably accomplish separating operation by providing a torque limiter on a separation roller brought into contact with a normal rotation roller, the working force of which satisfies a designated relational expression. CONSTITUTION:The working force (Ts/R) of a torque limiter (coiled spring 28) provided on a separation roller 21 is set larger than the frictional force (up Ns) between a plain paper sheet and the separation roller 21 and smaller than the frictional force (mut.Ns) between a special sheet and the separation roller 21.

A control circuit 11 is so composed as to turn a MOSFET 17 and a diode bridge 18 on with the voltage of a Zener diode 16 for a set time such as 2 minutes after a high pressure discharge lamp 4 is turned off and to short-circuit the device 8. Consequently, the circuit 5 generates only normal starting pulses after the set time passes since the discharge lams is turned off. As a result, high pressure pulses are prevented from being left as they are when a high pressure discharge lamp is out of order and the dielectric strength is lowered.
