Title: Electrophotographic transfer paper
Inventor: KADOMA KENJI
IPC: G03G7/00
Filed: 1990-11-30
Abstract: PURPOSE:To obtain the electrophotographic transfer paper superior in sizability and toner fixability by coating the surface of the transfer paper with a surface sizing agent composed essentially of a styrene-acrylic acid copolymer. CONSTITUTION:The electrophotographic transfer paper is prepared by coating the surface of paper containing alkyleneketene dimer(AKD) or alkenyl succinic anhydride(ASA) with the surface sizing agent composed essentially of the styrene-acrylic acid copolymer. An adverse effect of an inner additive sizing agent on the toner fixability can be especially reduced by coating the surface of the paper with this surface sizing agent, especially, containing a styrene weight ratio of >=0.30 together with oxidized starch by a size press or gate roll coater(GRC), thus permitting the obtained electrophotographic transfer paper to be superior in toner fixability and sizability.

Title: Vibrating gyro
Inventor: MAENO TAKASHI
IPC: G01C19/5649
Filed: 1993-12-28
Abstract: PURPOSE:To eliminate an influence due to torsional vibrations which have been applied and to detect only an angular velocity with high accuracy by a method wherein bending vibration signals which are excited respectively inside the same plane and whose phase is opposite are added to detection signals of individual bending vibrations in directions of two axes. CONSTITUTION:A torsional driving signal is supplied to an electrode plate 6e from a drive circuit 19, the driving signal is applied to piezoelectric elements 3c2, 3c3, and a vibrator is torsionally vibrated in a resonance state. When an angular velocity is given to the vibrator, bend vibrations are generated by Coliolis' force. An element 3a is subjected to the bending vibrations inside the X-Z plane, and voltages VBX1, VBX2 which are proportional to vibration amplitudes are amplified 11a, 11b via electrode plates 6a1, 6a2. A voltage which is proportional to a strain, in the Z-axis direction, generated by the bend vibrations and whose sign is opposite is superposed on both voltages whose waveform is in an opposite phase. Consequently, both voltages are added by an adder 17a, a signal V'BX which has removed a component proportional to torsional vibrations is input to a detection circuit 13, and an angular velocity signal Vout is output. Also an element 3b for bending vibration detection inside the y-z plane is detected 14 via the same processing process.

Filed: 1989-12-28
Abstract: PURPOSE:To correctly clamp a word line drive line by providing an NMOSFET between a voltage dropped power supply line and a word line drive line in the clamp circuit of a DRAM. CONSTITUTION:The drain of a clamping NMOS Q5 is connected to the voltage dropped power line WDL to which dropped voltage VD1 is outputted from a voltage circuit 6, and a source and a gate are connected to the word line drive line WDL. The configuration of a memory cell or a bit line, etc., is the same as the conventional one. Through this configuration, the upper limit of the word line drive line WDL is limited below VD1 + Vth5. Vth5 is the threshold voltage of Q5. Namely, the word line drive line WDL can be clamped at the potential a little higher than the dropped voltage VD1 below the supply voltage Vc level an internal circuit such as a sense amplifier uses as internal supply voltage. Accordingly, the word line drive line can be clamped correctly even through the configuration to use supply voltage drop obtained from an external part. As for Q5, it is advantageous to set it to be of gate width of the same extent as the selected transistor of the memory cell.
