Title: Valve switching control system for multiple switching type turbine control device
Inventor: IIJIMA TADAHIKO
IPC: F01D21/14
Filed: 1982-02-22
Abstract: PURPOSE:To enable to actuate a standby line that remains inoperative to return even while a  valve is being switched, by a construction wherein a multiple control system is employed for a  control valve adapted to regulate flow rate of steam, and a standby line is provided for estimating a condition under which the control valve is switched, and thereby utilizing a signal  thus estimated as an initial signal by a line adapted to instruct the valve switching sequence. CONSTITUTION:A control device adapted to control a steam regulating valve which is provided  intermediately in a steam pipe line through which steam generated by a boiler is introduced  into a turbine is provided with a multiple line including a line for giving a driving signal to  the valve and at least one standby line. The standby line is designed to obtain a signal 40 that is an estimated instruction of total valve opening amount in a sequence such that the standby  line takes up data concerning an actual load MW, turbine's actual speed Nf and opening  amount Cp of the regulating valve, and the actual load Mw is added to the difference between  the actual speed Nf and the rated speed NR divided by a speed regulation rate delta. Arrangement is also made such that a function generator 43 that is a reciprocating function of regulating  valve bias generator (not shown) may generate a signal 44 equivalent to the time passed after the valve switching instruction is started, with basis on a signal 42 that is obtained by substracting the signal 42 from the opening amount 41 of the regulating valve.

IPC: G11C11/401
Filed: 1983-02-21
Abstract: PURPOSE:To extend a power source voltage margin, by precharging a dummy cell until a memory cell is set to the non-selected state after a sense amplifier is operated and forming stored information of the memory cell and a reference voltage with the same power source voltage. CONSTITUTION:A MOSFETQm is turned on to connect a capacitor Cs to a common data line DL, and a change of the potential of the data line DL which is generated in accordance with the electric charge quantity stored in the capacitor Cs is sensed, thus reading information. This change of the potential of the data line DL due to the electric charge quantity stored in the capacitor Cs appears as a very minute signal. A dummy cell DC is provided as a reference for detection of this minute signal. Even if a considerable variation (bump) is generated in a power source voltage Vcc in the time when a memory array is not selected, the memory cell and the dummy cell hold the storage level and the reference voltage level still in accordance with the power source voltage Vcc in the preceding operation state.

Title: Data bus control circuit for semiconductor integrated circuit
Inventor: KIMURA KAZUO
IPC: G06F3/00
Filed: 1991-02-20
Abstract: PURPOSE:To prevent the infiltration of an external noise to a composite semiconductor integrated circuit without causing trouble such as the propagation delay of a signal and the fall of drivability. CONSTITUTION:The data bus of a CPU 1 is connected to an input/output terminal 4 through a two-way bus buffer 7. The signal propagation direction of the bus buffer 7 is determined by the level of the signal outputted from an AND circuit 8. When the CPU 1 outputs the read-out signal of a low level, the signal outputted from the AND circuit 8 becomes the low level, and a buffer circuit 72 outputs the signal given to the input/output terminal 4 from the outside to the data bus 2. On the other hand, when the CPU 1 outputs the read-out signal of a high level, the signal outputted from the AND circuit 8 becomes the high level at the rise-up of a clock signal CK, and the buffer circuit 71 outputs the signal on the data bus to the input/output terminal 4.

Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To execute bartering operation by lightly opening/closing operation and to keep sharpness for a long period by preventing unreasonable biting force caused by twisting force by simple structure. SOLUTION: At scissors for barbering obtained by pivotaly attaching upper and lower blades 1 and 2, which are obtained by forming a handle part and blade parts in one body, by an axis 3 in the state of being freely openable and closable, a notched groove 7 of a circular-arc cross section is provided extending the entire width of the surface of the base tip part of a blade part 1a in the vicinity of the axis 3 of one blade 1 to form this notched groove part to be an elastic and flexible part. Thus, in spite of opening/closing the blades 1 and 2 while twist-operating at the time of barbering operation, the operating force is absorbed by the elastic and flexible part to execute light barbering operation while biting both of the blades with prescribed contact pressure.
