Patent JP-S5918705-A (JP)
Title: Manufacture of copolymer, product and use
Inventor: JIEEMUSU HENRII BARETSUTO
IPC: B01J20/26
Filed: 1983-06-30
Abstract: Polymer beads are produced by forming an agitated suspension of lightly crosslinked seed particles, at least substantially free of protective colloid, swelling these by addition of monomer under polymerization conditions while balancing suspension conditions, feed rate, agitation and polymerization rate to avoid, discourage or minimise particle agglomeration, continuing polymerisation after monomer feed is completed and separating the resulting beads. The monomers in the seed particles and monomer feed comprise styrenic and/or aliphatic ethylenically unsaturated units and a suitable light degree of crosslinking of the seed particles is 0.1 to 5%. The beads when macroreticular are useful as adsorbents and when containing ion exchange functional groups, are useful, whether gel or macroreticular, as ion exchange resins. Preferred beads exhibit multi-stage swelling in a swelling solvent and have a birefringence pattern under polarised light characteristic of high bead stress.

Title: Lifetime testing circuit of transistors
Inventor: WAGOU MINORU
IPC: H01L21/66
Filed: 1977-09-28
Abstract: PURPOSE:To protect the element being tested during lifetime testing by inserting a diode in the same direction as emitter current in series to an emitter lead and applying forward bias to the emitter-base junction. CONSTITUTION:A diode 4 is inserted in the same direction as emitter current in series to the emitter of the transistor being tested. Should the element 1 self-oscillate, the diode 4 blocks this and therefore the breakdown of the emitter-base junction is prevented and the decrease of HFE is prevented as well.

Title: Image sensor
Inventor: SUETSUGU KENICHIRO
IPC: H04N1/028
Filed: 1988-05-13
Abstract: PURPOSE:To obtain an image sensor with high performance and low cost by clipping an elastic connector between a sensor substrate receiving a reflected light from an original to be read and a sensor drive circuit board. CONSTITUTION:An elastic connector 9 is set in the pressing state between a photoelectric conversion array 4 and a printed circuit board 7 to connect the photoelectric conversion element 4 and the printed circuit board 7 electrically. Since the elastic connector 9 held in a resin holder 10 is employed for the connection between the photoelectric conversion element 4 and the printed circuit board 7, the positioning of the elastic connector 9 is facilitated and set stably in the state that the prescribed condition is matched. After they are assembled in this way, the photoelectric conversion element array 4 and the printed circuit board 7 are separated easily even if the printed circuit board 7 is defective and the good components are used again.

Filed: 1987-05-13
Abstract: PURPOSE:To provide a larger display part and a paper support to retain printing paper stably by installing the paper support capable of retaining printing paper in an upright position at the rear of a printing part and also a display part for entered data. CONSTITUTION:A paper support 9 is installed which retains printing paper P in an upright position at the rear of a printing part consisting of a platen 5 and a thermal head 8, and a display part 14 for data entered through an input key 4, is installed at one side of the support 9.

Title: Scanner
Inventor: KAJITA NORITSUGU
IPC: H04N1/04
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To make a reading head small in size, light in weight and low in cost by constituting the image reading part of the reading head to be rotatable and forming a reading stand into the shape so that the distance from an original is fixed in matching with the movement of the image reading part. SOLUTION: A fulcrum shaft is on an axis which is the same as that of a light receiving element, which is arranged on a CCD sensor 1 and which converts a light into an electric signal and the shaft rotatably supports an optical assembly 3. A driving means 5 is constituted of a motor and a gear or the like for rotating and driving the optical assembly 3 with a shaft 4 as a center axis. The optical assembly 3, the fulcrum shaft and the driving means 5 are mounted on the reading head 6. Moreover, an original stand 7 is of a shape by which an original surface is set to be uniformly separated by a distance (r) with a light receiving line of the CCD sensor 1 as the center. Therefore, the distance between the original stand 7 of the scanner 101 and the CCD sensor 1 is normally fixed in spite of the rotation of the assembly 3.  Then the length of an optical path is always equal, and an image without distortions is obtained.

Abstract: PURPOSE:To carry out the extraction in high extraction efficiency with a small energy consumption in extracting acetic acid from an aqueous solution of the acetic acid containing a metallic salt of sulfuric acid, by using an organic extracting agent consisting of a tertiary amine containing sulfuric acid and an organic diluent. CONSTITUTION:Acetic acid in an aqueous solution of the acetic acid containing a metallic salt of sulfuric acid, e.g. an aqueous solution of the acetic acid discharged from a process for preparing cellulose acetate, is extracted with an organic extracting agent consisting of a tertiary amine containing sulfuric acid in a molar amount of 1-6 times of that of the metallic salt of the sulfuric acid and an organic diluent by the countercurrent multistage method. For example, the extraction is carried out by using the organic extracting agent consisting of tri-n-octylamine and 3,3,5-trimethylcyclohexanone and sulfuric acid in an extractor devised to promote the frequency of dispersion and joining coalescence of droplets, e.g. a mixer-settler, and the moisture is removed from the extract. The bottom temperature of a column for removing the acetic acid is kept at 140-150 deg.C to give the acetic acid from the top thereof, and the regenerated extracting agent is obtained from the bottom and circulated for reuse.

Title: Hinge for wing
Inventor: TADA MITSUJI
IPC: E05D3/00
Filed: 1994-05-31
Abstract: PURPOSE:To perform a job for mounting adjustments in an easy manner by bending one side of hinge plates in parallel with a securing pin, and installing each of mounting holes at both sides of a boundary of this bend. CONSTITUTION:Two end edges 3a and 4a being opposed to each of paired hinge plates 3 and 4 are connected to each other rotatably around a securing pin 5. These paired hinges 3 and 4 form a normal circular unloaded hole 6 and an oblong unloaded hole 7 with a progressive die. In addition, the hinge plate 4 to be attached to the side of a door D is bent as far as the specified angle at a boundary 8 of a cross direction nearly central part in a direction of the securing pin 5 extending. In the case where there is a slippage in the working of a door stop or the like between a door frame 2 and the door D, a surface contact of the hinge plate 4 to the door frame 2 is adjusted to some extent, whereby its mounting is adjusted. At this time, there is some clearance occurring in a gap between the hinge 4 and the door frame 2, but the circular unloaded hole 6 is subjected to 'countersinking' in advance, so that any lost motion in the hinge plate 4 is preventable for a long period of time owing to a force to be produced on a taper surface of a flat countersunk head screw.

SOLUTION: In the communication system with an optical fiber transmission line 3, at least one correction module 4(4A...4N) based on chirp optical fiber grating corrects color scattering caused by the optical fiber 3. The chirp optical fiber grating has a group delay characteristic τ (ω) that represents ripples around a nominal linear profile as a function of an optical signal frequency. In order to minimize the effect of the ripples, correction is conducted so that an operating point is placed in a limited gradation area of a curve denoting deterioration of system performance due to color scattering with respect to a given fiber length 3.
