Abstract: PURPOSE:To obtain a developing device capable of removing a ferroelectrostatic charging toner layer strongly adhering to the surface of a developer carrier, reducing the uneven electrostatic charging of toner, and further preventing surface fogging even in the case of small grain size toner. CONSTITUTION:A piezoelectric element 22 is set on the back surface of a developing blade 20 and fine vibration by the mechanical vibration of the element 22 is applied to the magnetic toner 6 of one-component developer on a developing sleeve 8 at and near the abutting part of the blade 20 on the sleeve and force toward the image part of a photosensitive drum 2 is imparted to the toner 6 on the sleeve 8. Potential V1 between the image part and a non-image part and potential V2 for imparting the force toward the sleeve 8 to the toner 6 of the image part are set as a peak value, and alternating voltage that a central value between V1 and V2 is between the image part and the non-image part is impressed on the sleeve 8 as developing bias. The ferroelectrostatic charged toner layer on the sleeve 8 is removed by the fine vibration, and developing bias is impressed, so that the surface fogging is prevented occurring even in the case of using the small grain size toner.

Abstract: PURPOSE:To reduce the deterioration of magnetic permeability even in a high frequency region by arranging uniform size magnetic fine particles at a small interval. CONSTITUTION:Nitrided iron fine particles for example are arranged at a predetermined interval in the direction of a magnetic field, elongated lengthily in a straight line like a string of beads. The arrangement forms a rectangular lattice and is fixed in resin in a cross section perpendicualarly to the direction of the magnetic field. Herein, the fine particles are aligned at a predetermined distance by entropic repulsive force of a surface active agent coated layer, the distance being controlled by the kind and molecular weight of the surface active agent used. Hereby, higher magnetic permeability can be realized up to a high frequency region.

IPC: B32B27/18
Filed: 1987-12-15
Abstract: PURPOSE:To realize a transparent electromagnetic wave shielding sheet which has a high strength and maintains a high reliability for a long term and in which a transparent plastic sheet is simply buried (sticking) without a possibility of peeling-off by employing a meshed conductive woven cloth as a shielding layer. CONSTITUTION:A woven cloth woven so as to form meshes is prepared. The woven cloth is impregnated with conductive coating of adhesive resin and conductive metal powder dispersed in the adhesive resin and dried to make a conductive woven cloth. Then the meshed conductive woven cloth is laminated with transparent plastic. The method of lamination is such that a transparent plastic film is extruded on the meshed conductive woven cloth and coated on the cloth or by thermocompression bonding. Otherwise, the transparent plastic film may be applied to the cloth by dry lamination. With this constitution, a shielding sheet in which the meshed conductive woven cloth and the transparent plastic are unified can be obtained. As the conducting part is made of the meshed cloth, the sheet is flexible and, as the cloth is impregnated with the conductive coating, the conductive coating film is not peeled off.

Title: Monitoring device for film by chemical deposition of metallic organic matter
Inventor: RI BAN
IPC: C23C16/52
Filed: 1994-12-20
Abstract: PURPOSE: To accurately monitor the thickness and composition change of a crystal thin film when growing by causing a plurality of laser beams with different wavelengths to fall on the surface of a sample. CONSTITUTION: Each of two laser beams with mutually different wavelength emitted from laser beam generators 10 and 20 is caused to fall at an angle of 71 deg. in the vertical direction of the surface of a sample 2. Each of two beams reflected from the surface of the sample 2 is caused to fall on photo detectors 70 and 90 of the sample 2 by a filter 50. Therefore, the photo detector 70 detects light from the generator 10, and the photo detector 90 detects light from the generator 20. Signals from the photo detectors 60, 70, 80, and 90 are inputted to a computer 3 for comparison and analysis. That is, as the thickness of the growing thin film increases, the intensity (beam reflectivity) of the reflected beam changes due to interference. Thus, the growth speed of the thin film can be formed by analyzing the period of the interference pattern of each beam whose reflectivity changes.

Title: Cap device for ink jet printer
Inventor: HANAOKA YUKIHIRO
IPC: B41J2/165
Filed: 1990-11-21
Abstract: PURPOSE:To obtain a printer having narrow breadth without specific power for closing a cap by providing a cap roller having an axis of rotation parallel with a nozzle of an ink jet head consisting of elastic member and shutting off the nozzle of the ink jet head by the cap roller. CONSTITUTION:When a printing is completed and a capping operation is necessary, a carriage drive motor 10 is driven and a carriage 5 is stopped just before an ink jet head 4 contacts with a cap roller 1. Next, a nozzle 4-a of the ink jet head 4 drives the carriage drive motor 10 until an axis of rotation 3 of the cap roller l coincides with a position in the direction of printing column and stops it. As the cap roller 1 is made of rubber, an overlap with the nozzle 4-a is absorbed by the elasticity. Thus, for closing the cap, a shutting off of the nozzle can be done by only stopping the carriage at the position where the cap roller arranged at a fixed frame coincides with the nozzle of the ink jet head.

Title: Wedge lift
Inventor: NOJIMA KOZO
IPC: B66F7/06
Filed: 1994-11-28
Abstract: PURPOSE: To cope with the use, in which ascent/descent of an elevating platform is very frequent, without enlarging the size of the device or complicating the construction of the device by rotating a pair of eccentric cam members and oscillating opposed arms in the vertical direction, thereby lifting/lowering the elevating platform. CONSTITUTION: When a plate cam 321 rotates, a roller 328 relatively rotates/ moves along a lower surface 310a of an elevating block 310. Since the center of rotation of the plate cam 321 is parted by the prescribed distance from the center of rotation of the roller 328, the elevating block 310 is lifted upward, with a maximum displacement obtained by adding a radius of the roller 328 to a distance between the center of rotation of the roller 38 and that of the plate cam 321, thereby lifting the elevating platform 100. With this contrivance, this device can be used for very frequent ascent/descent of the elevating platform without enlarging the size of the device or complicating the construction, compared with a conventional wedge lift.
