Title: Ink jet recording sheet and its manufacture
Inventor: KONO AKIRA
IPC: D21H27/00
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To manufacture an ink jet recording sheet of superior ink absorbability provided with dots of small diameter and almost of the round shape and generating no powder dropping. SOLUTION: An ink jet recording sheet is formed of pulp as a main raw material, and the corona discharge treatment is applied with the 70-150 W/m2/ minute power to be treated on the surface of a base paper containing a sizing agent of 0.1% or more to pulp and then an ink acceptive layer is applied on a corona discharge treated surface of the base paper within 60 minutes after the treatment. The corona discharge treatment is carried out just before the coating of the ink acceptive layer by an on-coater corona discharge treatment device. Also the wetting properties of the surface of the base paper on which the sizing agent is destroyed by the corona discharge treatment is improved by 3-5 dyne/cm2 more than the wetting properties of an untreated base paper.

Filed: 1993-09-17
Abstract: PURPOSE:To provide a static elimination brush which is constituted to prevent a paper sheet being cought on a holder (the occurrence of paper jam) even when the static eliminator is installed in a position where the holder part thereof makes contact with a conveyance printing paper. CONSTITUTION:A protection sheet 5 to prevent a conveyance paper, being an object to be static-eliminated, from making contact with a holder 3 is attached on the jacket side of a holder 3 to hold the electrode 1 of a static elimination brush. The protection sheet 5 is formed of a high density polyethylene sheet or polyimide sheet with a thickness of, for example, approximate 0.1-0.2mm, and has smoothness enough to form a sufficient guide surface for the conveyance paper. Further, even a holder made of an aluminum foil having low rigidity is additionally functioned as reinforcement. The direction of the protection sheet 5 is extended such that the sagging side is pointed to the outside so that burrs generated in a process to manufacture the protection sheet are not exposed to the obverse.

Abstract: PURPOSE:To form an area of full white level or a prescribed color level without erasing a picture by inputting the information of an area inserted with the full white or prescribed color level or the area to be erased so as to interrupt the operation of the line memory. CONSTITUTION:A delete area signal output circuit 19 outputs a low level when the picture data of a delete area is written in a line buffer 6 by a delete area data from a CPU 13 and when the picture data at the outside of the delete area is written in the line buffer 6, the circuit 19 outputs a high level. A gate circuit 11 uses an output signal of the delete area signal output circuit 19 so as to give a write clock to the line buffer 6 from a synchronizing control circuit 4 to the line buffer 6 only when the picture data at the outside of the delete area is written in the line buffer 6 and masks the write clock to the line buffer 6 from the synchronizing control circuit 4 when the picture data in the delete area is written in the line buffer 6. Thus, an optional main scanning area in the picture is deleted and the full white or prescribed color area is formed to an optional position in the picture without deleting the picture.

Title: Dielectric constant detecting device for fuel
Inventor: OKADA AKIRA
IPC: G01N27/22
Filed: 1991-09-12
Abstract: PURPOSE:To accurately detect methanol content rate in fuel by compensating temperature characteristic of dielectric constant of the fuel through temperature characteristic of dielectric constant of insulating material. CONSTITUTION:A conductive electrode 3 provided on the way of a fuel passage 2, and a single-layer-winding coil 4 which fuel is introduced between it and the electrode 3, it is molded with insulating material, and the coil cylindrical face is oppositely arranged and spaced by a decided distance against the electrode 3, are provided. Under the condition in which gasoline mixed with methanol is let flow in the passage 2, a series circuit of series resistance 10 and the coil 4 is input from an amplifier 15 to a 0 phase comparator 11, and both phase differences are compared with each other. Because dielectric constant of fuel is monotonously decreased as temperature rise and reversely dielectric constant of mold material is monotonously increased as temperature rise, resonance frequency of the coil 4 depending upon the dielectric constant of fuel is compensated, and hence alcohol content rate is accurately detected by detecting dielectric constant of fuel.

Abstract: PROBLEM TO BE SOLVED: To increase the temp. margin for low power recording and to stabilize the overwrite process by forming layers in such a manner that the coercive force of an auxiliary recording layer is higher than the coercive force of a recording layer at room temp. and that the intensity of sublattice magnetization of transition metal elements is superior to the intensity of sublattice magnetization of rare earth elements in the auxiliary recording layer.

A reproducing layer as a read-only layer is formed between a substrate 1 and the M layer 2 to improve C/N. Or, exchange coupling force controlling layer is formed between the M layer 2 and the W layer 3 to control the exchange coupling force of the layers. Thereby, the exchange coupling force is cut at least at room temp., and initialization of the W layer 3 and transfer of the magnetization direction from the W layer 3 to the M layer 2 can be smoothly carried out.

Abstract: PURPOSE:To prevent the decrease of a recording signal level and the decrease of S/N ratio caused by the decrease of the level by providing a magnetism shielding member on surfaces other than a region, wherein a magnetic path is formed of main pole and a magnetic recording medium. CONSTITUTION:The magnetic field, which is formed by the application of a current through a coil 15, forms the closed loop in the path through an auxiliary pole 11, a main pole 12 and a magnetic recording medium located at the lower side. Thus, the recording and reproduction are performed for the magnetic recording medium. Meanwhile, the mutual facing surfaces forming the magnetic path between the poles 11 and 12 and the rear sides of two surfaces of the pole 11 other than the facing surface to the magnetic recording medium are covered with a magnetic shielding member constituting a side part 9. Therefore, external magnetic field is prevented from entering the pole 11 through the two surfaces. Thus, the decrease of the level of the recording signal of the magnetic recording medium caused by the external magnetic field can be prevented.
