Title: Lower word line driver and semiconductor memory device utilizing the same
Inventor: JIYO TEIGEN
IPC: G11C8/14
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce the area of a whole memory chip, facilitate the high integration and achieve the high speed operation by a method wherein a lower word line driver is composed of two N-MOS transistors which are operated as a pull-up driver and a pull-down driver. SOLUTION: In a lower word line driver, an N-MOS transistor MN1 pulls up a driving step-up voltage Vpp L level and transmits it to a lower word line SL and an N-MOS transistor MN2 pulls down the lower word line SWL with a ground level 0V. At that time, a potential Vpp H higher than the voltage VPPL is applied to the gate of the transistor MN1 to transmit the VPPL voltage of a signal Px which operates the lower word line driver selectively to the lower word line SWL as it is. As the lower word line driver is composed of the two N-MOS transistors, the area of a whole memory chip can be reduced and, further, a time loss caused by the delay between driving signals can be eliminated and the high speed operation can be achieved.

Title: Still picture id transmitting method and still picture receiving terminal equipment
Inventor: MOROTOMI TETSUAKI
IPC: H04N21/435
Filed: 1993-11-30
Abstract: PURPOSE:To transmit the ID signal of a still picture without providing any special demodulator for a control signal by adding the individual ID signal to each still picture during a video signal period and establishing compatibility with a digital control signal. CONSTITUTION:At a still picture receiving terminal equipment 13, a TV channel is tuned by a tuner 14 corresponding to the instruction of a control circuit 15, and the source still picture is demodulated by a demodulation circuit 16. In this case, an 10 detection circuit 17 detects the superimposed ID signal corresponding to a transmitted still signal and compares whether it matches the set ID code by the control circuit 15. When these ID codes matches, the ID detection circuit 17 outputs an instruction to record the presently inputted still picture signal to an image recording circuit 18. On the other hand, when displaying the target still picture on a monitor TV 20, the control circuit 15 changes over a video switch 19 and selects the reproduced signal of the image recording circuit 18. Thus, the required still picture can be selected out of plural still pictures by giving information to be set to the circuit 17.

Title: Shield device
Inventor: AKESAKA TOSHIO
IPC: E21D9/08
Filed: 1994-12-07
Abstract: PURPOSE: To stabilize the advanced direction of a shield device by enabling a rotor to have the rotation axis intersecting with the rotation axis of a shaft so that elements on sides of a conical outside surface and a shield main body only are separated from the rotation axis of the shaft to the shield main body radial outside. CONSTITUTION: A shield device 10 is moved forward by revolving a rotor 18 around the axis 12 as the rotation axis of a shaft 16 and the axis 38 as the rotation axis of the rotor itself. The axis 38 is intersected with the axis 12 in a point P0 around the front end of the rotor 18 so that an element on the side of a shield main body 14 only is separated from the axis 12 to the radial outside thereof.  As a result, even if an eccentric amount of the rotor 18 for the shaft 16 is increased, when the shield device 10 is moved forward, the uppermost front end of a cutter section 42 is not required for making a large turning movement around the axis 12, and notwithstanding that the rotor 18 makes the turning movement around the axis 12 and a rotational movement around the axis 38, the advanced direction of the shield device is stabilized since it is less apt to suffer ground characteristic brought into contact with the cutter section 42 of the rotor 18.
