Title: Base paper for wallpaper, obtained by paper-making, and method for producing the same
Inventor: SUZUKI KUNIO
IPC: D21H27/20
Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a base paper sheet for making wallpaper sheets, obtained by monolithically wet-papermaking a nonwoven fabric layer for wallpaper with a backing paper layer in a step for making the backing paper sheet, without adhering a nonwoven fabric for wallpaper sheets and the backing paper sheet by using an adhesive and without using a press for the adhesion to produce a wallpaper sheet with a three dimensional structure and a high quality, and to provide a method for producing the same.  <P>SOLUTION: The base paper sheet for the wallpaper sheet is obtained by monolithic wet paper making of the nonwoven fabric for wallpaper with the backing paper layer, wherein the fabric contains ≥20% but ≤70% fusing fiber. The method for producing the base paper for the wallpaper comprises superposing a nonwoven fabric web for wallpaper with a backing paper web after forming each web at each forming part but before drying them and then drying the webs to integrate them. Thereby, the method solves former problems that, as conventional nonwoven fabric wallpaper sheets are obtained by binding the nonwoven fabric for the wallpaper with the backing paper, a process for binding is required, the adhesive is needed and so cost is increased, presswork in the binding step causes degradation of precious bulkiness of the nonwoven fabric for wallpaper, so, a wallpaper having three-dimensional appearance is hardly produced and a quality problem is caused.  <P>COPYRIGHT: (C)2004,JPO

Title: Multiplex encoded information separator and decoder
Inventor: TOJIMA SHIGEKI
IPC: H04N19/423
Filed: 2002-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem at the time of switching a program between a multiplex encoded information separator/distributor for separating appropriate encoded information from a multiplexed stream and an image decoding system having an image decoder for storing image encoded information sequentially in an internal buffer and decoding it while reading out sequentially that incomplete frame data is displayed at the time of switching because the start of new encoded information can not be recognized after switching.  <P>SOLUTION: At the time of switching a program, a multiplex encoded information separating/distributing processing 101 adds a marker to the head of new encoded information so that an image decoding processing 102 can recognize the start of new encoded information. When the image decoding processing 102 finds a marker indicative of the head of new encoded information during encoding operation of the encoded information, a control processing 104 interrupts an image signal conversion processing 103 until the image decoding processing 102 can produce correctly decoded image frame data.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for separating adamantanetriols, capable of simply and efficiently separating the adamantanetriols from a mixture of the adamantanetriols of which the number of hydroxy group is 3 and other adamantanols, such as adamantanemonools, adamantanediols, and adamantanetetraols, of which the numbers of hydroxy groups are each different from 3.  <P>SOLUTION: In this method for separating the adamantanetriols, an aqueous solution and/or an aqueous dispersion which contains the adamantanetriols and the other adamantanols of which the numbers of hydroxy groups are each different from 3 are contacted with ethyl acetate at a temperature of ≥40°C to form a two-phase mixture composed of an aqueous phase and an ethyl acetate phase, then the ethyl acetate phase is separated from the aqueous phase, and further the ethyl acetate phase is cooled, so that crystals of the adamantanetriols are deposited. The adamantanols of which the numbers of hydroxy groups are each 3 or less are distributed into the ethyl acetate phase, and the other adamantanols of which the numbers of hydroxy groups are each 4 or more are distributed into the aqueous phase. Because the adamantanemonools and the adamantanediols are not deposited when cooled, the deposited crystals comprise the adamantanetriols with high purity.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To solve the conventional problem that Ni materials hitherto used as a material for a cathode compartment of a brine electrolysis cell using a gas diffusion electrode are expensive and insufficient in strength and require increased sheet thickness and, as a result, an anode-cathode distance is increased and accordingly voltage becomes high.   <P>SOLUTION: As the material for the cathode compartment in which the gas diffusion electrode is held, a stainless steel material having a composition containing, by weight, 15 to 30% Ni and 20 to 30% Cr is used. Unlike general- purpose stainless steel materials, the stainless steel material having the above specific composition is less expensive than the Ni materials and further has high strength and can reduce the amount of the material used. Accordingly, the thickness of the catholyte compartment can be reduced and voltage loss can be decreased and operations at low voltage are made possible.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a printer head driving circuit of an ink jet printer which is capable of efficiently correcting a deviation of output wave-shape with respect to inputted wave shapes.   <P>SOLUTION: A driving wave-shape generating circuit 80 generates a driving wave-shaped COM that drives an electrostrictive element 17. A head driver circuit 18 selectively drives the electrostrictive element 17 with a printing data SI. An A/D conversion circuit 302 converts the driving wave input into a digital value for the head driver circuit 18. A head control circuit 101 compares the input wave shape data to the head driver circuit 18 digitally converted by the A/D conversion circuit 302 with the wave shape data to be generated next by the driving wave shape generating circuit 80. A head control circuit 101 corrects the waveform so that the wave shape that comes next for the head driver circuit 18 approaches an original driving wave shape by adding a difference to or reducing it from the wave shape data to be generated thereafter. Therefore, the driving wave shape preliminarily desired to be outputted can be charged to the electrostrictive element 17.  <P>COPYRIGHT: (C)2004,JPO
