Title: Semiconductor integrated circuit device
Inventor: NUMATA KENJI
IPC: G11C11/409
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To improve a sense speed and an operation margin by connecting back gates of two pieces of MOS transistors constituting a differential amplifier and commonly connecting sources to the common gate source node of these transistors and always making a back gate voltage zero. SOLUTION: An NMOS sense amplifier NSA is formed to a well separated from another circuit area, and a well potential control circuit 102 is provided for this. That is, the substrate potential of two pieces of n channel MOS transistors Qn1 , Qn2 of the NSA are controlled by the output potential VSB of the well potential control circuit 102 in addition to a regular substrate bias VBB. Thus, the time from the time when an activated signal is raised until sense operation is started in the NSA is shortened. Further, even when a source voltage VCC is lowered, the sense operation with an excess voltage becomes possible. That is, the NSA amplifying an L level side minute signal among bit line sense amplifiers is accelerated.

Abstract: PURPOSE:To accurately transfer corresponding page memory data to a normal recording paper by controlling the output of a paper ejection signal for executing the switching processing of a page memory corresponding to detected paper left in a machine to a printer part. CONSTITUTION:A digital copying machine controller 103 judges whether or not the detection of the paper left in the machine is completed.

Abstract: PURPOSE:To record automatically the amounts of changes in the concave and convex of a road in the directions of the width and length thereof at the same time, by recording automatically the amount of fluctuation of ground-contacting measuring ends of a measuring frame with an inclinometer and the amount of inclination of the measuring frame in the direction of the width of the road, while moving the frame along the surface of the road to be measured. CONSTITUTION:A number of ground-contacting measuring ends 2 each having a measuring wheel 7 attached to the lower end are provided movably in the vertical direction in a measuring frame 4 in such a manner that they are joined to the sliding parts of variable resistors 9 in a group which are connected to a constant voltage source 8, and thereby the amounts of changes in the concave and convex of a road surface to be measured are transduced into electric outputs. Moreover, an inclinometer 3 constituted by forming the sliding part of a sliding resistor 10 connected to the same constant voltage source 8 into a vertical rod 11 pointing constantly downward in the vertical direction is fixed to the measuring frame 4, and thereby the amount of inclination of the frame 4 is transduced into an electric output. Both electric outputs are inputted in a changing amount recording device 12 and an inclination amount recording device 13 which are mounted on an automobile, and thus automatic records are obtained simultaneously. As to the amount of unnecessary fluctuation caused by the inclination of the ground-contacting measuring ends 2 in a line, original data can be compensated easily by the inclinometer 3 provided in the measuring frame 4, and thus the state of distribution of the amounts of the concave and convex of the road surface can be quantified precisely.

Title: Image forming device
Inventor: HIRABAYASHI HIROMITSU
IPC: G03G15/16
Filed: 1987-03-13
Abstract: PURPOSE:To improve the final transfer rate to a transfer material without decreasing the transfer rate to an intermediate transfer medium by impressing a bias in the direction of transferring a toner image on the intermediate transfer medium to a pressurizing means onto the pressurizing means. CONSTITUTION:A bias power supply 13 is disposed between a press roller 12 and a conductive base layer 2a of the intermediate transfer medium. Said bias is a DC power source which is of the same polarity as the polarity of a bias 10 and has high potential. Such an electric field which displaces the toner toward the roller 12 side is, therefore, generated between the conductive base layer of the intermediate transfer medium and the press roller. More specifically, the force F directed toward the transfer material acts thereon. The toner is thereby satisfactorily transferred to the transfer material without increasing the pressurized contact force of the roller 12 with the intermediate transfer medium and the formation of a sharp image is permitted.

Title: Radio wave absorber and production thereof
Inventor: WAKAMATSU KOICHI
IPC: H05K9/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To enhance radio wave absorbing characteristics by providing a part for fixing a resistive layer and a reflective layer thereby keeping an accurate distance between them. SOLUTION: The radio wave absorber has a member C for fixing a resistive layer B and a reflective layer A. An insulating material, e.g. resin, glass or mortar, is employed as the material of the member C in view point of radio wave absorption performance and resin is preferred in view point of workability and price. The member C may be shaped arbitrarily and it is preferably shaped such that the resistive layer B and the reflective layer A do not move easily after being fixed. Since an accurate distance can be kept easily between the resistive layer B and the reflective layer A, a radio wave absorber where the radio wave absorption characteristics can be enhanced at a frequency especially requiring absorption of radio wave can be obtained.
