Title: Plate-shaped laminated catalyst
Inventor: TATE TAKAHIRO
IPC: B01D53/94
Filed: 1989-03-31
Abstract: PURPOSE:To keep catalytic activity such as denitrification activity and to reduce the thickness of a catalyst by laminating a dense ceramic substrate layer and a ceramic porous layer to a substrate and supporting a catalytically active component in the porous layer or on the surface thereof to prepare a plate- shaped laminated catalyst. CONSTITUTION:A substrate layer composed of a dense ceramic material is formed on a substrate composed of a heat-resistant plate-shaped body such as a metal plate, a metal net, an inorg. sintered substrate or an inorg. fiberboard using a technique such as a flame spraying method or a plasma spraying method. A ceramic porous layer composed of aluminum oxide or silicon oxide similar to the substrate layer is formed by adapting an impregnation method or a coating method. Subsequently, a catalytically active component is supported in the ceramic porous layer and/or on the surface of said porous layer by employing an impregnation method or a coating method to form a plate-shaped laminated catalyst. The obtained catalyst has a large specific surface area because of its porous layer and is reduced in its catalytic activity.

Title: Low-jitter wideband voltage-controlled oscillator
Inventor: RUIJI PENZA
IPC: H03K3/03
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To achieve a high hysteresis by decreasing the short-term instability of output frequency while remarkably improving ability for preventing the interference of high frequency noises coming from a supply rail and a controlled voltage line. SOLUTION: Each sturbed inverter at a voltage controlled oscillator has an output transfer gate related to that oscillator. A pair of complementary switches MVN and MVP consisting of this transfer gate are commonly controlled together with the correspondent current source of each sturbed inverter according to a frequency control voltage Vc and a voltage difference Vdd-Vc between the supplied voltage and the control voltage. The frequency generated by that oscillator is linearly proportional to that control voltage Vc and inversely proportional to the square root of supplied voltage Vdd, and high noise immunity and improved frequency stability can be provided.

Abstract: PURPOSE: To facilitate packaging and transporting of sheet-like optical elements and to facilitate discrimination of the front and rear, etc., at the time of packaging. CONSTITUTION: The many sheet-like optical elements 2 are formed on a sheet base material 13 consisting of a triacetyl cellulose(TAC), etc., by a thermal transfer method and a protective member 3b consisting of a resin material, such as polyvinyl chloride, is formed on the front surface (functional surface). Next, the sheet base material is cut apart to the individual sheet-like optical elements 2 and thereafter, these elements are temporarily fixed onto the continuous protective member 3a, by which a sheet-like optical element package 1 is produced. As a result, the protective member 3a fixed with the many sheet- like optical elements 2 can be taken up in a roll form, folded, easily packed and transported. The discrimination of the front and the rear is easy and sure if the elements are fixed to the protective member 3a by previously determining their directions.  Since the functional surfaces are protected by the protective member 3b, the elements are kept substantially free from flawing and dust pickup at the time of packing and packaging.

Filed: 1978-06-28
Abstract: PURPOSE:To detect simply a storage device which is formed by the storage element of a low output signal, by generating a potential difference between both input terminals in case that input terminals of a differential amplification-type level converter are restricted to a fixed voltage. CONSTITUTION:At a write time, when transistor 6 is turned off, capacitors 4 and 5 at the output end of differential amplifier 1 have a potential lower or higher than the operating center voltage of differential amplification-type level converter 13 by a prescribed value due to resistances 14 and 15 connected to diodes 9 and 11 of a power source circuit. Then, the potential at input terminals F and E of converter 13 have a voltage lower or higher than the operting center voltage by a prescribed threshold voltage. Immediately after these restriction voltages are released at a read time by the turning-on of transistor 6, one of voltages at terminals E and F has the level lowered and the other has the level raised by the charging voltage of capacitors 4 and 5, and the magnitude of output signals from storage elements is detected by comparator 13, thereby removing simply storage devices formed by low-output signal storage elements.

Filed: 1988-03-31
Abstract: PURPOSE:To prevent a light shielding paper from getting out of a slit by increasing a frictional resistance between the slit and the light shielding paper by providing projections to the inside surface of the slit. CONSTITUTION:Each two projections 16 are formed alternately to the inside confronting surface 14, 15 of a slit 13.

Inventor: HAGA KEIJI
IPC: B32B15/08
Filed: 1986-04-04
Abstract: PURPOSE:To obtain a laminated sheet having a uniform thickness and reduced in coefficients of dimensional fluctuation, warpage and distortion, by a method wherein a plurality of sheets to be laminated each containing 500 or less air bubbles/cm<2> are inserted between two running belts to be heated under pressure through the running belts.

After the base material is impregnated with the resin by this method, said base material is dried at 100-160 deg.C to obtain a resin impregnated base material containing 500 or less air bubbles. Thereafter, a required number of the resin impregnated base materials being sheets to be laminated are stacked and a metal foil is arranged to both surfaces or single surface of the stacked one to obtain one set and a plurality of sets are held between two upper and lower advance running belts and heated, for example, at 150-170 deg.C under pressure of 10-30kg/cm<2> and a laminated sheet is obtained by continuous molding due to so called double belt press.

Abstract: PURPOSE:To connect two pipes completely in the center of a liner by forming a conductive member into a cylindrical shape, providing a protrusion rising in an inner-peripheral direction in the center in the axial direction of an inner periphery, and coating the inner periphery other than the protrusion with insulating resin. CONSTITUTION:A protrusion 11 is protrudingly-formed in a ring shape along the peripheral direction on the inner periphery in the center in the axial direction of a liner 10. At this time, the height of the protrusion 11 is formed so that the diameter R of a circle which connects its ridge part along the peripheral direction may become a little smaller than the outside diameter L of conduit pipes 3, 4 to be connected. The inner periphery of the liner 10 other than the protrusion 11 is coated with insulating resin. For connecting the pipes 3, 4, the pipes 3, 4 are inserted from both the ends of the liner 10, and pipe ends 3a, 4a are made to come into contact with the protrusion 11, so that electric current passage is formed between a pair of right and left clips, and the connection condition of the pipes 3, 4 is judged by watching lighting of a lamp. Then a thermal shrinkage cylinder 5 fitted onto the connected part is heated for shrinkage, thus completing the connection of the pipes 3, 4.
