Title: Image forming apparatus
Inventor: HIRAGUCHI HIROSHI
IPC: G03G15/05
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus in which print particles on a print roller are activated sufficiently to form a high density image and an image can be formed at high speed. SOLUTION: An image forming apparatus comprises a print roller 30 for supporting print particles 38, and a back face electrode 44 for forming an electric field between the print roller 30 and the electrode 44. A head 52 having holes 56 is interposed between the print roller 30 and the electrode 44. The head 52 is provided with two electrodes 58a, 58b arranged closely to the holes 56 in order to increase the field strength thus flying the print particles toward a sheet 8 while passing between the head 52 and the back face electrode 44. Since the print particles 38 are attracted with a stronger force as compared with a case where an image signal is applied only to one electrode, a high density image can be obtained even if the duration of the image signal is short.

Title: Production of polyamide resin
Inventor: MIYAMOTO KAZUKI
IPC: C08G69/26
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a polyamide resin useful for parts of automobile, etc., having excellent color tone, tensile strength, etc., by subjecting a specific crystalline polyamide to a preconcentration process in the presence of a phosphorus-based catalyst, then polymerizing the primary condensate and further highly polymerizing. CONSTITUTION:This crystalline polyamide resin (preferably copolyamide) contains an amide structure formed from a 4-14C aliphatic diamine (preferably a 6C or 12C aliphatic diamine) and terephthalic acid, has preferably 230-340 deg.C melting point and has a repeating unit of structural units of at least one of formula I to formula IV.

Title: Driving method for magnetic biasing device
Inventor: IWATA MASAO
IPC: G11B11/10
Filed: 1987-12-28
Abstract: PURPOSE:To turn a permanent magnet to a target direction in a short time without vibrating it by flowing a current to flow in an electromagnetic coil in a forward direction for definite time, and afterward, flowing the current to flow in the electromagnetic coil in the reverse direction just before the permanent magnet faces to the direction of the magnetic flux of the electromagnetic coil. CONSTITUTION:When the current flows in the forward direction of the electromagnetic coil 12, the magnetic flux 14 facing upward is generated, and the permanent magnet 13 starts to turn toward the direction of an arrow mark 15 as being accelerated. When this state is maintained, the permanent magnet 13 continues to turn so as to face to the same direction as the magnetic flux. Then, after the definite time, if the current of the electromagnetic coil 12 flows in the reverse direction when the turning of the permanent magnet 13 approaches the vicinity of the direction of the objective magnetic flux, the magnetic flux of the electromagnetic coil 12 is inverted, and simultaneously, rotational torque acting upon the permanent magnet 13 is inverted as well. Then, the direction of the permanent magnet 13 can be determined by flowing the current in the electromagnetic coil 12 as inverting its direction into the forward direction when the permanent magnet 13 faces to the direction reverse to the direction of the magnetic flux. Thus, the vibration of the permanent magnet can be converged and stopped in a short time.

Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a ghost by relatively inclining the rear surface of a glass plate on which an original is placed to the axis of light entering into a first mirror from an original surface. SOLUTION: A platen glass 22 is arranged to be tilted to a horizontal plane by about 1 deg. above halogen lamps 20. Light (harmful light) reflected on the outside of the effective ranges of mirrors M1 and M2 and returned to the rear surface of the platen glass 22 is reflected on the rear surface, but the rear surface of the platen glass 22 does not perpendicular to the axis of light entering into the first mirror M1 from the original surface (angle α<90 deg.), so that the harmful light is reflected at a large angle of reflection on the rear surface of the platen glass 22 and is deviated remarkably from the axis. Since the harmful light does not reach an image forming lens 16, the occurrence of the ghost can be prevented.

Title: Isolation of phenylalanine
Inventor: HIGUCHI CHOJIRO
IPC: C07C227/38
Filed: 1991-12-18
Abstract: PURPOSE:To enable high-efficient recovery of phenylalanine of high purity by adding a specified amount of ammonium sulfate to an aqueous solution containing phenylalanine. CONSTITUTION:Ammonium sulfate is added to an aqueous solution containing phenylalanine so that it exists more than 20wt.% and less than 40wt.% and the phenylalanine crystals precipitated are filtered at a temperature lower than 30 deg.C whereby phenylalanine can be isolated efficiently. The use of ammonium sulfate can markedly lower the solubility of phenylalanine by increasing the concentration of ammonium sulfate without its precipitation even at a temperature lower than 30 deg.C, thus pure phenylalanine can be isolated. The concentration of phenylalanine in the aqueous solution is preferably higher than 0.7wt.% but lower than 20wt.%. In addition to ammonium sulfate, aspartic acid can be added as a contaminant. As the phenylalanine aqueous solution, may be used the hydrolytic product of the reaction mixture in the aspartame production.

Title: Method and equipment for dehydrating sludge and similar substance
Inventor: ARUBERUTO BEERU
IPC: B01D25/12
Filed: 1995-12-01
Abstract: In a process and assembly to de-water sludge (9) and similar substances, the sludge is charged into an enclosed main chamber (20) incorporating a filter surface (24, 25), and subjected to hydrostatic pressurisation. Following expulsion of the water, the chamber is opened and the filter cake removed on the filters (24, 25). The novelty is that before de-watering in the main chamber, the sludge charge is first held in an intermediate chamber (3), linked to the main chamber (20), whose inlet (6) is then blocked while the sludge is subjected to hydrostatic pressure which forces it into the main chamber (20). The incoming sludge is retained in a holding tank (5) until required for treatment.

Abstract: PURPOSE:To enable appearance of a multiplicity of items to be inspected simultaneously by dividing a light which is reflected on a surface of an object to be inspected into two directions and allowing one light to detect intensity of a transmission light only and the other to detect intensity of a diffusion constituent only. CONSTITUTION:When there is a foreign object 7 at a blade 6, absorption and diffusion of light occur from a surface of an object to be inspected to a reflection light, thus enabling a transmission light 8 and a diffusion light 9 to be produced.

One of the divided light advances downward, the diffusion light 13 is cut off by a slit 15, and only the transmission light 11 advances straight, is focused at a light-receiving lens 16, and enters a light receiver 17. Also, the transmission light 12 is cut off by other optical mask 18 and only diffusion light advances straight, is focused at a light-receiving lens 19, and then enters a light receiver 20. The light receivers 17 and 20 detect the diffusion light 13 and the transmission light 12 and detect a defect of multiple items of the object to be inspected simultaneously.
