Title: Data acquisition circuit
Inventor: TOBARI TSUTOMU
IPC: H03M1/12
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide the sampled value of a small through rate to an AD converter with no use of an analog switch, a fast sampling pulse holding capacitor nor a buffer amplifier. SOLUTION: This circuit includes a differentiation circuit 11 which differentiates an input signal 1, a strobe circuit 12 which generates a sine wave 3 and a cosine wave 5, a pair of multiplication circuits 20 and 60, a variable gain amplifier 14 and a differential amplifier 15. Then the circuit can provide the sampled value having its through rate substantially equal to zero when an AD converter 18 performs the AD conversion since the signal of a terminal 8 is equal to a signal having its through rate of zero that is coincident with the value of the signal 1 in an AD sampling mode of AD conversion. The circuits 20 and 60 are Gilbert type multiplication circuits and can be easily turned into an IC including the converter 18.

Title: Semiconductor device and its manufacturing method
Inventor: NAKABAYASHI TAKASHI
IPC: H01L21/768
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To suppress damages to a gate oxide film and open contact holes different in depths. SOLUTION: A polycrystalline silicon film 118 is deposited on a first oxide film 117 reflecting an undercut on a P-type semiconductor substrate 111, and further a second oxide film 119 is deposited, and the upper surface of the second oxide film 119 is completely flattened. When first and second contact holes 121, 121' are opened, first etching is performed until the polycrystalline silicon film 118 and opening is performed until each of electrodes by second (third) etching. At this time, the difference in film thickness of a contact hole formation region is absorbed by the polycrystalline silicon film 118 at a contact hole etching step. For this reason, overetching for a gate electrode is not required so much. Therefore, it is possible to suppress damages to a gate oxide film.

Abstract: PURPOSE:To supply the same amount of toner as consumed toner in a developer to a containing part from a hopper and to keep the toner concentration in the developer constant by providing a partition means with plural opening holes between a developer containing part and a toner containing part. CONSTITUTION:The developer in the containing part 16 is conveyed by the rotation of a sleeve 12. The part of the developer forms a developer layer with a prescribed width on the sleeve 12 through a blade 18 and the sleeve 12, while the excessive developer regulated by the blade 18 is returned toward the containing part 16. Initially the developer 14 is filled in the containing part 16, and the toner is prevented from entering the containing part 16 from the hopper through the opening holes of the partition 24. When the toner is used by a developing action, a fresh toner sent by an agitating vane 26 goes into the containing part 16 through the opening holes of the partition 24 from the hopper in terms of a space corresponding to the volume of the used toner. Toner in quantity roughly equal to the used toner is made up to maintain the toner concentration.

Abstract: PURPOSE:To stabilize a sensor output and to stabilize variation in output characteristics with temperature by forming magnetostrictive metal in strips and fixing and forming the stripes so that the direction of the strips is at a specific angle to the lengthwise direction of a circular tube. CONSTITUTION:The stripes of Co-based amorphous alloy 3 which has magnetic strain are fixed on the external surface of the center part of the circular tube 1 made of 45% Ni-Fe alloy so that the lengthwise direction is at 60 deg. (45-80 deg. or at least 100-135 deg.). The difference in coefficient of heat expansion between the alloy 3 and circular tube 1 is 1.5X10<-6> (at least <=2X10<-6>). Then pressure applied from the pressure intake 2 of the circular tube 1 is transmitted into the circular pipe 1, which deforms elastically to displace the alloy 3. The stress and displacement reduce the magnetic permeability of the alloy 3 to cause inductance variation. The inductance value decreases almost linearly with the pressure up to 300kgf/cm<2> and corresponds to the pressure one to one. The pressure is measured by utilizing this relation.

Title: Method and device for contact electrostatic charging
Inventor: OFUKU EIJI
IPC: G03G15/02
Filed: 1991-09-27
Abstract: PURPOSE:To obtain an excellent electrostatic charging potential even when an applied voltage is relatively low by making the electrostatic capacity of a contact electrostatic charging member smaller than that of an electrostatically charged member. CONSTITUTION:The contact electrostatic charging member A is made to abut on the electrostatically charged body B and voltages are applied from an AC power source VAC and a DC power source VDC between those contact electrostatic charging member A and electrostatically charged body B, which is charged electrostatically. In this case, the electrostatic capacity of the contact electrostatic charging member A is made smaller than that of the electrostatically charged body B. The voltages applied between the contact electrostatic charging member A and electrostatically charged body B are distributed according to their electrostatic capacity value when the electrostatic capacity of the contact electrostatic charging member A is made smaller than that of the electrostatically charged member B, the majority of the voltages is applied to the contact electrostatic charging member A. Consequently, charges migrate quickly in the contact electrostatic charging member A to cause electrostatic charging not by aerial discharging, but other electrostatic charging processes such as direct charge migration and frictional electrostatic charging as well as aerial discharging, thereby speeding up the electrostatic charging processes.

Abstract: PURPOSE:To obtain a fired board which is free of defects such as a cracking or alligatoring through suppression of overcooling at the side ends compared with the middle part of the board by providing a refractory material having an emissivity for far infrared rays above a specified value at positions in the space inside the furnace facing the side ends of the fired object at least at a part of the, cooling region. CONSTITUTION:A cooling zone is a space where cooling air is sent from outside the furnace into an upper space and a lower space inside the furnace by a cooling pipe 8. For a cooling zone the inner wall 3a at the parts facing the side ends 5a of a fired object is built from a refractory material 9 with an emissivity of 80% or more for far infrared rays; an alternative is that a far- infrared ray radiant plate 10 is provided at a position corresponding to each of the side ends 5a of the fired object. A refractory material having an emissivity of 80% or more for far-infrared rays can be obtained by, for example, pressure molding and reducing firing of a compound of 73% SiO2, 15% Al2O3, 5% Fe2O3, 3% LiO, 2% MgO, and 2% CaO. This method enables obtaining a fired board which is free of defects such as a crack or alligatoring.
