Patent JP-H11355099-A (JP)
Title: Transversal filter
Inventor: TAKEYARI RYOJI
IPC: H03H15/00
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a filter for equalizing the base band signal of a Gb/s class by connecting the input terminal of a variable gain amplifier to a transmission line A and connecting the output terminal to a transmission line B so as to fix the sum of propagation time between the input terminals of adjacent variable gain amplifiers and propagation time between the output terminals. SOLUTION: The input terminal of the variable gain amplifier is connected to the transmission line A and the output terminal is connected to the transmission line B so as to fix the sum of propagation time between the input terminals of adjacent variable gain amplifiers and propagation time between the output terminals. Namely, variable gain amplifier cells 1a and 1b are arranged at an interval with which the time for propagation through an input line 2 and an output line 3 can become half the delay time T required for a transversal filter. Therefore, the output of the variable gain amplifier cell 1b is added while being delayed just for T from the variable gain amplifier cell 1a. A tap coefficient is controlled by the gain control terminal of the amplifier cells 1a and 1b and the gain of the respective amplifier cells 1a and 1b is set to the desired value.

Title: Vaporizer for burner
Inventor: YAMAMOTO HAJIME
IPC: F23D11/02
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent the corrosion of the surface of a pipe due to flames to improve the durability of a vaporizer for a burner by providing a corrosion- resistant layer over the surface of a pipe forming a fuel vaporizing part. SOLUTION: A piece of cloth 6 wrapped around a pipe 1 is impregnated with kerosene and a kindling is put into an opening 7 of a cylinder frame 3 to ignite the piece of cloth 6. Next, if kerosene is fed into a pipe 1 from a fuel tank by means of a pump, the piece of cloth 6 serves as a preheating material so that the kerosene is vaporized and the vaporized fuel is blown off from a fuel blowoff nozzle 2 and ignited. And flames blown off from the nozzle 2 is sent outwardly through a cylinder 9 so as not to be diffused and passed through a vaporizing part 5 so as to be blown off from an end of the cylinder frame 3. At that time, the surface of the pipe 1 is plated with chromium (corrosion-resistant layer), and hence the surface of the pipe is not corroded even if it is exposed to flames and no hole is formed in the surface of the part 5.  And due to the heat resistance of chromium plating, the durability of a vaporizer for a burner can endure for about 200 to 300 hours.

Title: Production of water-dispersible sheet
Inventor: MORITA TETSUO
IPC: D21H13/06
Filed: 1993-07-01
Abstract: PURPOSE:To produce a sheet having high water dispersibility simpler and more efficiently than the conventional method. CONSTITUTION:In making a water-insoluble fibrous carboxymethyl cellulose (CMC fiber) alone or a mixture of the water-insoluble fibrous carboxymethyl cellulose and a fibrous raw material into a sheet in production of a water- dispersible sheet, the water-insoluble fibrous carboxymethyl cellulose or the mixture is dispersed into an aqueous solution containing at least one (treating agent) selected from a group of a carbonate and a hydrogencarbonate of an alkali metal and ammonium to make the sheet. Since the treating agent of CMC fibers acts as a releasability improver as well as a neutralizing agent at a stage before dry part, the treating a gent hydrolyzes ester bond during the dry part and acts as the neutralizing agent for remaining carboxymethyl group, the water-dispersible sheet can be efficiently produced without requiring a complicated post-process and appearance of the objective sheet can be maintained especially by controlling esterification degree of CMC fibers.

Abstract: PURPOSE: To expand the expanding outside circumferential plate at the removing of a coil body by making the arc portion of more than half the circumference of the outside circumferential plate expandable.  
     CONSTITUTION: Pipes of respective cylinders 14 are connected by couplers 26a, 26b and solenoid valves 27a, 26b are operated to operate clamp cylinder and lock cylinder. An outside circumferential plate 6 is put in an expandable state by the release of the free end of the expanding outside circumferential plate having detention pawls and the release of sliding shafts 10, 10, whereby the basket K is tilted and erected up to the perpendicular position. More specifically, if a tilting machine G is erected up to perpendicularity by a tilting cylinder 30, the expanding outside circumferential plate 6 comes to the lower side along with its erected position and becomes expanded by the gravities of the steel pipe coil J and expanding outside circumferential plate 6 and the sliding shafts 10, 10, sliding block 7. The coil J lowers to the opened outside circumferential plate 6 side and its contact with the stationary outside circumferential plate 2 side becomes loose, thus it becomes loadable on a hook conveyor I. The smooth removal of the coil J is made possible through the hook insertion.

Thus, the reception address of the information of a circuit 4 is switched from a terminal main body 6 (normally) to the circuit 3, and the information after the command information is returned to the central processor 1 via the circuits 3,4 and a circuit 2 as folding information. Thus, in the central processor 1, the transmission system including the serial-parallel conversion circuti 2 in the terminal device can be checked by comparing the transmission information with its folded information.

Filed: 1979-12-17
Abstract: PURPOSE:To obtain excellent drawing-in characteristics to the signal in amplitude- phase modulation, by picking up the next zero crossing as effective, only when the peak value immediately before the zero crossing is a given value or more. CONSTITUTION:The input signal 25 in amplitude-phase modulation is fed to a negative peak detection circuit 32, positive peak detection circuit 31, and zero crossing detection section 33 via a BPF. When the amplitude of negative peak value of the signal 25 is a given value or more and the zero is intersected toward positive direction, FF46 is set and FF42 is reset. Inversely, if the amplitude of positive direction peak value of the signal 25 is a given value or more, FF46 is reset and FF41 is reset and the result of zero crossing detection is output at a terminal 47. Thus, since the pickup is made only when the peak value immediately before the zero crossing is a given value or more, the drawing-in and noise characteristics can be increased.
