Title: Measuring method of moisture content in sand
Inventor: IHARA SUSUMU
IPC: G01N27/22
Filed: 1978-02-28
Abstract: PURPOSE: To realize measurement always at high precision, by keeping the pressing pressure of measuring electrode against the sand above the specified pressure.  
     CONSTITUTION: A measuring electrode has an electrode 52, which is connected to the central conductor of an coaxial cable, and an electrode 53, which is connected to an external conductor or the earth, secured to an insulating plate 51, and measures the electrostatic capacity of the sand including the moisture between the electrodes 52, 53, by inserting the electrodes 52, 53 into the sand. By keeping the pressing pressure of the measuring electrode against the sand abobe 100 g/cm 2 , the dispersion of the electrostatic capacity may be very slight, and the measurement of the electrostatic capacity may remain almost constant if the moisture content is constant. Thus, high precision measurement may be realized.

Title: Recorder
Inventor: SATO KENJI
IPC: B41J13/10
Filed: 1989-02-03
Abstract: PURPOSE:To improve carrying and copying ability in the approach of a thick recording paper to a photosensitive drum by having a guide surface of a guide plate situated on a tangent of the photosensitive drum that passes the pressure surface of a carrier roller. CONSTITUTION:A thick recording paper P1 is carried by a carrier roller 6, and is guided by a guide surface 9a of a guide plate 9 until it reaches a photosensitive drum 2. Since the guide surface 9a is on a tangent A, even though the firmness of the paper is strong, the recording paper P1 is carried smoothly without being jammed. Since the frictional force of the guide plate 9 and the recording paper P1 is small, the recording paper P1 is not carried smoothly and failure in copying or folding of the paper do not occur. Even when the recording paper P1 is short, jamming, or failure in copying on the rear edge of the recording paper P1 just after it passes through the guide plate 9 do not occur. Since the carrying direction of the recording paper P1 is the direction of the tangent A even just before approaching a drum, contact between the drum and the recording paper P1 is good to ensure good copying.

Title: Manufacture of display device
Inventor: SANO KO
IPC: H01J11/24
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a display device capable of suppressing degradation of brightness in burning a phosphor layer with a simple process without using a large-scaled processing device. SOLUTION: After completing assembly of a PDP, argon gas is sealed in a discharge space 23, and a discharge pulse voltage is repetitively applied between a retaining discharge electrode 8 and an address electrode 10. Argon ions 41 generated by discharge are accelerated by the discharge pulse voltage, and a surface layer of a phosphor layer 4 is sputtered. During the process of burning the phosphor layer 4, the surface layer causing transformation and degradation of brightness is removed by sputtering, and the phosphor layer 4 develops original brightness. A large-scaled processing device is not necessary because a discharge mechanism of the PDP itself is used. After the discharging process, the argon gas is eliminated and neon.xenon mixed gas suitable for normal operation is filled and a PDP as a product is completed.

Abstract: PURPOSE: To improve the cooling efficiency at a liner wall surface by disturbing a temperature border layer being generated continuously with the wall surface.  
     CONSTITUTION: Burner liners 12 are arranged so that they are widened toward the downstream from a fuel nozzle by a plurality of cylindrical members having different diameters. The end part of a cylinder 13 has an outwardly widened inclination, and, on the other hand, a large number of throttle openings 15 are provided around the entire periphery of a double structure consisting of a cylinder 13 and a cylinder 14, and a ring 16 concurently used as a spacer between the cylinders 13 and 14 is provided. By this constitution, cooling air 17 flows out of throttle openings 15 along the inclined part of the cylinder 13 and comes into collision with the wall surface of the cylinder 14. As a result, a temperature border layer generated in the proximity of the wall surface is disturbed, whereby the wall surface cooling effect can be improved under the same air layer.

Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a transfer sheet suitable for the transfer of an image to the surface of an article of three-dimensional shape which has the same performance as a transfer sheet using a conventional polyvinyl chloride resin film as a base material film and does not cause an environmental disruption by using a laminated film made up of at least, two resin layers as the base material film. SOLUTION: In the transfer sheet comprising a layer 2 for transferring a pattern, formed on a base material film 1 in a freely peelable manner, the base material film 1 is a laminated film composed of at least, two laminated layers such as an olefinic resin composition layer 11 containing an amorphous polyolefin resin and a resin layer 12 composed of an ethylene resin and/or a crystalline polypropylene resin. The olefinic resin composition layer 11 containing the amorphous polyolefin makes the base material film 1 properly pliable and thermally deformable. Consequently, it is possible to obtain the transfer suitability equivalent to that of a transfer sheet using a polyvinyl chloride resin film. In addition, a harmful gas and a harmful incineration ash are not generated when this new transfer sheet is incinerated.

IPC: C30B15/00
Filed: 1994-02-23
Abstract: PURPOSE:To suppress the carbon concentration in the tip and rear end of a single crystal within a specific value by carrying out the effective baking treatment of a member, constituting an apparatus for growing a crystal and made of graphite. CONSTITUTION:This method for producing a compound semiconductor single crystal is to carry out the blank ignition in two stages in a vacuum heating device before growing the single crystal by using a liquid-encapsulated Czochralski (LEC) process. The blank ignition in the two stages is carried out by heating a member made of graphite at a temperature without exceeding 600 deg.C in a vacuum in the case of a GaAs single crystal, e.g. 400 deg.C for an optional time and then at a higher temperature than 600 deg.C e.g. 1000 deg.C for an optional time. Oxides such as O2, H2O or AS2O3 remaining on the member made of the graphite are initially volatilized and As sticking to the member, constituting a heater, a heat insulating material, etc., and made of graphite is then volatilized to prevent the volatilized As from recombining with the oxides. After the blank ignition, the apparatus for growing the crystal is cooled to ambient temperature in a vacuum or an inert gas. After cooling, the member made of the graphite, together with the raw material, is then installed in the apparatus for growing the crystal to start the growing of the single crystal.

Title: Magnetic separator for recovering waste
Inventor: GOTO YOSHIYUKI
IPC: B03C1/00
Filed: 1995-02-14
Abstract: PURPOSE: To automatically, efficiently, and magnetically separate waste to be recovered such as cans by installing a magnet having a specific magnetic gradient in a belt between a following drum and a driving drum in addition to a magnet on the side of the following drum onto which the belt for transferring the waste to be recovered is wound. CONSTITUTION: When waste to be recovered such as steel cans and aluminum cans are magnetically separated, a belt 4 is transferred with the rotation of a driving drum 5. With the use of magnetic attraction of the first magnet on the side of a following drum, after only steel cans are pressed and transferred by a partition panel 10 while they are being attracted to the belt 4, they are attracted by the magnetic attraction of the second magnet 6 which is attached to a support member 7. In this process, the magnetic attraction of the second magnet 6, since the magnetic gradient of the magnet is set up so that the magnetic force decreases toward the driving drum 5, steel cans drop from the belt 4 at a specified position. Besides, aluminum cans, which are not attracted, drop from projected end of the periphery of a nonmagnetic external rotary drum 3.
