Title: Pump impeller
Inventor: WADA MASAMI
IPC: F04D13/06
Filed: 1981-03-16
Abstract: PURPOSE:To prevent corrosion of a core of a rotor and a secondary winding in a pump wherein an axial gap type motor is used as a driving source, by embedding both of the core and the secondary winding in the united form in a body of synthetic resin shaped into an impeller. CONSTITUTION:An external ring-like conductor 2b and an internal ring-like conductor 2a are disposed outside and inside in the radial direction of a core 1, respectively. Both of the conductors are embedded in the incorporated form in a synthetic resin body 4 formed in the shape of a pump impeller 3. Although a thinner gap face 5 provides a higher characteristic of a motor, a too much thinner gap face may contain more pin-holes or the like to result in an unsatisfactory corrosion effect. An ideal thickness may be 0.8-2.0mm.. Because the core and the winding are thoroughly wrapped up in the synthetic resin, there is no possibility of corrosion and hence, unexpensive aluminum may be used for the secondary winding 2.

Title: Wound wire
Inventor: YAMADA MASAHARU
IPC: B65D85/04
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To allow a wire to be fed while the wire is being packaged and also allow the wire inside to be recognized by wrapping an outer circumference and both upper and lower outer faces of the wire wound into a roll by a uniaxially stretched heat-shrinkable plastic sheet which heat-shrinks only in a direction of the outer circumference and by leaving an internal side at the center of the roll unwrapped. SOLUTION: A uniaxially stretched heat-shrinkable plastic sheet C heat- shrinking in a direction of an outer circumference of a wire roll is used. The heat-shrinkable plastic sheet wider than a height 1 of the wire roll B is put over along the outer circumference 1 of the wire roll B, wherein overlapping parts of the sheet are integrated by heat-fusing. Internal faces 5, 6 at a center of the wire roll are kept open without the sheet. Thus since the internal faces of the wire roll are not wrapped, no wrinkles may occur on the plastic sheet even after heat-shrinking. The wire can be fed out without unpacking due to openings at the center of the wire roll. The plastic sheet is transparent, whereby the wire inside can be recognized while being packaged to prevent erroneous delivery.

Title: Controller for dark attenuation of photoreceptor of electronic copying machine
Inventor: NAKAYA FUMIO
IPC: G03G15/045
Filed: 1982-03-15
Abstract: PURPOSE:To obtain an invariably optimum dark potential at a developing stage by providing a voltage applying means between an electrostatic charger for charging the surface of a photoreceptor and a developing device which develops an electrostatic latent image formed at an exposing stage. CONSTITUTION:The voltage applying means 6 consists of a couple of conductive rolls 6a separated from each other in the rotating direction of the photoreceptor 1 and endless aromanized ''Mylar '' extended between those conductive rolls 6a. The surface of the photoreceptor 1 charged by the charger 2 has dark attenuation until it reaches the 1st voltage applying means 6, but once it reaches the voltage applying means 6, the charges on the surface of the photoreceptor 1 are canceled by the contacting with the aromanized ''Mylar '' 6a, so the dark attenuation is not caused. Even after the image exposure of the photoreceptor 1, the dark attenuation is prevented by a trailing voltage applying means 6, so the dark attenuation is caused only in a section O-A between the charger 2 and the 1st voltage applying means 6, a section B-C between the voltage applying means, and in a section D-E between the trailing voltage applying means 6 and a developing roll ta, thereby reducing the dark attenuation.

Abstract: PURPOSE:To obtain an image having an always uniform density without having development ghosts by forming the latent image of a development level in forward rotation or backward rotation or between paper, developing the image and removing the developed toner from an image carrying body. CONSTITUTION:The negative charged toner developed on a photosensitive drum 1 in the forward rotation, backward rotation or between paper flies toward a toner removing member 14 when an electric field is generated between the drum 1 and the member 14. The toner of small grain sizes which has high adhesive power to the drum 1a and relatively high tribo and the toner of larger grain sizes which has the low tribo and does not receive the influence of the power by the electric field hardly fly toward the member 14 and only the toner having the good developability is selectively recovered into a developing device 3. On the other hand, the toner and the components in the toner which exert an undesirable influence on the durability of the toner are introduced into a cleaning device 5 and are removed as the drum 1 rotates. The development ghosts to be generated by the toner of the degraded development performance remaining on the sleeve are thereby prevented and the image having always the uniform density is obtd.
