Title: Manufacture of lignocellulose molded plate
Inventor: MATSUZAKA YASUHIRO
IPC: B27N1/02
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To efficiently and stably manufacture a high quality molded plate at low cost by a method wherein an organic isocyanate compound used as the adhesive of the molded plate is singly sprayed on a lignocellulose-based material under the state being atomized so as to have the average of the droplet diameters of a mist of the specified value of less. SOLUTION: When an organic isocyanate compound as an adhesive is employed to a lignocellulose-based material so as to manufacture a lignocellulose molded plate by being pressed under heat and pressure, an organic isocyanate- based compound is singly sprayed on a lignocellulose-based material under the state being atomized so as to have the average of the droplet diameters of a mist of 40 μm or less. In this case, as a spraying method, an air spraying system is employed. At the same time, a hardener such as water or the like or an accelerator is added to the lignocellulose-based material. Further, a wax- based or metallic soap-based releasant is employed together with the hardener. Furthermore, as the accelerator having a skeleton of ethylene oxide, a polyether and/or a polyester polyols are employed.

Title: Position detecting apparatus
Inventor: KITAMURA ATSUSHI
IPC: G01D5/244
Filed: 1991-05-31
Abstract: PURPOSE:To make it possible to detect the change in position when a main power supply is turned OFF and to decrease power consumption by supplying power to an output part for the phase of the number of rotations and a number- of-rotation counting part during a period wherein the main power supply is turned OFF. CONSTITUTION:Even during a period wherein a main power supply is turned OFF, an output part 8 for the phase of the number of rotations and a number-of- rotation counting part 10, to which the backup power is supplied from a backup power supply part 13, are operated. Therefore, the number of rotations is detected. When the main power supply is turned ON at the next time, the number of rotations can be immediately found. When a signal in Z phase is detected, the amount of rotation is accurately found. When the signal in Z phase is one cycle per rotation, the amount of rotation is found within one rotation after the main power supply is turned ON. When the signal in Z phase is N>=2 cycles per rotation, the amount of rotation is found within 1/N rotation after the main power supply is turned ON. The output part 8 and the counting part 10 are not the circuits for counting many pulses for one rotation but the circuits for counting several cycles per rotation. Therefore power consumption is less.

Title: Battery
Inventor: OUBI FUMIO
IPC: H01M50/198
Filed: 1978-10-20
Abstract: PURPOSE:To raise air-tightness by giving an appropriate viscoelasticity to the material of sealed gasket and also to enhance stress-cracking resistance by adding a specific amount of an ionomer to polyethene or polypropylene as the material for  sealed gasket. CONSTITUTION:As the material for sealed gasket, a mixture of polyethylene or polypropylene and 10-30wt% an ionomer, an ethylene-dominated polymer whose anionic component taking part in the bonding between molecules is carboxyl group incorporated in the polyethylene molecule by copolymerization and whose cationic component is a metal, e.g., Na, K, Mg, etc., combining with cations among molecules where anions distributed in polymer molecule are present, is used. Thus, the stress-cracking resistance of polyethylene or polypropylene can be raised due to the uniform compatibility of polyethylene or polypropylene with ionomer because, although the mixture behaves like a rubbery elastomer at ordinary temperature, the electrostatic atraction between ions is weakened.

Title: Pencil lead
Inventor: OKABAYASHI HIROAKI
IPC: C09D13/00
Filed: 1995-04-28
Abstract: PURPOSE: To obtain a pencil lead having sufficiently high abrasion rate and density even as a pencil lead for a mechanical pencil having a diameter of <=0.9mm and practical strength and containing graphite as the sole component, as a result, giving a deep black written mark in contrast with the glossy mark of conventional pencil lead. CONSTITUTION: This pencil lead is produced by using at least an organic binder in combination with an extender material consisting of graphite and talc as a main material, kneading and extruding the material in the form of a thin string, baking the string and optionally impregnating an oily substance into the obtained pencil lead. The talc to be used in the process is preparatorily coated with a carbide film on the surface.  It is supposed that, in contrast with conventional talc having strong bond between the carbonized organic binder and the talc to resist the abrasion of the talc and give a written mark having low density, the bond between the carbonized organic binder and the carbide film on the surface of the talc becomes relatively weak at a microscopic interface in the present talc having a carbide film and, accordingly, the talc having carbide film is liable to fall off to promote the abrasion and prevent the lowering of the density.

Title: Method and device for feeding ash in burner type ash-melting furnace
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F23J1/00
Filed: 1993-06-01
Abstract: PURPOSE:To reduce the variation of the feeding of ash in quantity, secure the ash against entry of outside air and from escape of combustion gases, and efficiently melt the ash. CONSTITUTION:A compacting passageway 32 which is straight and has substantially the same cross section as the extruding body 14a of an ash pusher 14 is formed to a certain length toward the front from the pushing position of the extruding body 14a on the entry side of an ash-feeding hole 31 which is open from the bottom of an ash-feeding hopper 13 to a preheating chamber 19. Incineration ash G from the ash-feeding hopper 13 undergoes compaction under pressure at the compacting passageway 32 and assumes solidity to a certain density before being fed into the preheating chamber 19. As a result, ash can be fed at a constant rate independent of the quantity of ash in the ash-feeding hopper or in the preheating chamber and moreover the compacted ash is useful in the function of sealing to suppress fly ash.

CONSTITUTION:A catalytic compact 23 set up in a catalyzer supporter 24 comes into contact with a catalyzer supporting surface 19 by a knife edge 22, and this contact part 14 comes to a linear contact. Methane and water vapor out of a fuel gas inlet 8 comes into contact with a catalytic layer while they flow in a space 15 at a lower part of the catalytic compact 23, and converted into hydrogen gas, while a rib 3 stably holds an electrolytic plate 12. An electrolyte contained in this plate 12 tries to climb by way of an anode 11, a collector plate 10 and a porous corrosive layer on a surface of the rib 3 and reach to the catalytic layer 1, but a linear contact part 14 by the knife edge and the supporting surface exists in the point midway in the route so that it fails to reach the catalytic layer, thus a reforming catalyzer can keep its activity for a long period of time.
