摘要： PROBLEM TO BE SOLVED: To prevent frost from being left on the upstream side of a water repellent heat exchanger by providing a frost supporting member for preventing frost from migrating to the upstream side of the water repellent heat exchanger at the time of defrost operation in warming operation. SOLUTION: An outdoor unit 7 comprises a water repellent heat exchanger 8, a hydrophilic heat exchanger 9 and an axial fan 10. A frost supporting member 12 is disposed on the gas flow 13 side of the water repellent heat exchanger 8 in the outdoor unit 7. The hydrophilic heat exchanger 9 has a function for capturing water drops being scattered from the water repellent heat exchanger 8. A frost supporting member 12 is disposed on the gas flow 13 side of the water repellent heat exchanger 8. The frost supporting member 12 retards separation of frost from the water repellent heat exchanger 8 at the time of defrost operation and sustains contact of frost with the water repellent heat exchanger 8 thus realizing perfect defrost. In view of ventilation resistance and frost supporting, the pitch 21 of the frost supporting member 12 is optimally set in the range of 10-30 mm, more preferably in the range of 10-20 mm.

摘要： PROBLEM TO BE SOLVED: To catch minute waterdrops scattering from water-repellent surfaces within a heat exchanger and to melt them in the case when they are frozen, by a method wherein the surfaces of fins of the heat exchanger on the upstream side of air are made water-repellent, while the surfaces of the fins of the heat exchanger on the downstream side are made hydrophilic, and the shape of the fins of the heat exchanger on the downstream side is made waved. SOLUTION: Air flows in from a direction 4 and exchanges heat with a refrigerant flowing through a pipe 3. Surface treatment for water repellency is given to a heat exchanger 1 on the upstream side of the air and a large number of slits are cut-raised in fins of the heat exchanger 1. Surface treatment for hydrophilic properties is given to a heat exchanger 2 on the downstream side of the air and the fins of the heat exchanger 2 are provided with waved undulation. Water in the air condensed at the fins of the heat exchanger 1 on the upstream side of the air is formed in minute waterdrops, which scatter from the surfaces of the fins and reach the heat exchanger 2 on the downstream side of the air. Since the shape of the fins of the heat exchanger 2 on the downstream side of the air is waved and the surfaces thereof are given the treatment for hydrophilic properties, the waterdrops come into contact with the surfaces of the fins, become a thin liquid film and flows down.

摘要： PURPOSE:To increase the flux density of the end parts of recording electrodes and the bonding strength of toner in order to improve the resolution of recording picture by forming an organic thin film having a specific thickness between the recording electrode and a magnetic sheet. CONSTITUTION:An organic thin film 4 is formed on the surface of a magnetic sheet 1 by electrodeposition, cleaned with flowing water then dried. After forma tion of the organic film 4, the magnetic sheet 1 is laid on a base plate 3 on which recording electrodes 2 are produced by etching. They are then heated in a nonoxidizing atmosphere to polymerize and harden the organic film so as to bond together the magnetic sheet and the base plate. This method permits a uniform attachment of the sheet and the base plate with the magnetic sheet and the recording electrode insulated from each other and with a gap of 1-20 mum produced therebetween. Although the organic film can be provided on either magnetic sheet or recording electrode side, its film thickness is 1-20 mum.

摘要： PURPOSE:To restrain the fatigue of toner by supplying toner into a space, formed by an electrode needle and the image forming plane of a recording medium, through the use of a hopper beforehand without applying charge. CONSTITUTION:Toner 40 is supplied into the space, formed by the electrode needle 22 and the image forming plane of the recording medium 3, by the hopper 11 beforehand without applying charge. Since the toner 40 to which charge is not applied is not attracted to the surface of the recording medium 3 by a strong force, the force to move the toner with the rotation of the recording medium is weak, and it is not attracted to the recording medium 3; only the toner 40 to which charge is applied by the electrode needle 22 is strongly attracted to the surface of the recording medium 3. Therefore, small amount of toner 40 supplied from the hopper 11 is enough to form the same amount of pictures, and the fatigue of toner can be reduced.

摘要： PURPOSE:To obtain the recording electrode of high resolution by arranging plural conductive electrode groups in line on an insulation substrate and exposing, laminating and forming the edge surface and the edge part of the conductive electrode groups. CONSTITUTION:An insulating substrate 1 is the nonmagnetic material of a ceramic or a glass epoxy plate, etc., and the surface is provided with the plural, independent conductive electrode groups 2 arranged in line by etching or film- making technique, etc. An insulating permeability member 3 is provided on a surface on the conductive electrode groups 2 through a binding member 4 to obtain laminating constitution at a distance about 10mum-1mm from the one edge of the conductive electrode groups 2. The recording electrode 5 is constituted on the other edge of the conductive electrode groups 2 by connecting with the output side of an integrated circuit for electrode driving on the insulating substrate 1. Thus, it becomes possible to cope with high resolution of ten or more scanning lines/mm by reducing the thickness of copper foil to be etched.

摘要： PURPOSE:To record a sharp image by making the forming position of a toner chain always almost constant, by fixing a recording electrode and forming the toner chain extending from the leading end part of the recording electrode until contacting the surface of a recording member so as to incline toward the downstream side in the moving direction of the recording member. CONSTITUTION:The first magnetic roll 21 rotates in the direction shown by an arrow A to generate an alternating magnetic field and the toner 1 in a receiving container g is supplied to the region between a recording electrode 4 and a recording member 72 by the action of the magnetic field. The toner 13 falling on the recording member 72 is fed to the recording electrode 4 and bonded to toner 131 by the action of the magnetic force of a permanent magnet 6 to form a toner sump on the upstream side of the leading end part of the recording electrode 4. A toner chain 14 is formed along the line of magnetic force of the strong static magnetic field generated in the recording region. The toner of the lower part of the toner chain 14 is cut against magnetic force Pm by toner feed for Ft to be allowed to flow down toward the downstream side. The toner 16 having charge induced therein is strongly bonded to the recording member by an integrated circuit 42 and moves toward the downstream side of the recording region by the rotation of a drum.
