Title: Insulating method of field coil
Inventor: HASHIZUME AIICHIROU
IPC: H02K15/12
Filed: 1984-02-24
Abstract: PURPOSE:To automate steps by precipitating mica and water dispersive varnish resin by utilizing an electrophoresis to obtain an electrodeposited insulating layer, thereby eliminating a manual work. CONSTITUTION:A field coil 1 to be coated is dipped in an electrodepositing solution 2 filled in an electrodepositing tank 3, and an electrodeposited insulating layer is formed by an electrodepositing technique on a field coil conductor by a DC power source 4 with the coil 1 as an anode side and the tank 3 to become the opposite electrode as a cathode side. After a cure accelerator is coated and impregnated with the insulating layer, thermal curable resin is impregnated, heated and cured.

Title: Working and spare power supply switch control circuit
Inventor: TOYA HIROKAZU
IPC: G06F1/00
Filed: 1985-02-25
Abstract: PURPOSE:To minimize the transient variance on the load of a working/spare switching mode by turning off the comparator output in accordance with the actuation of a diode OR unit to switch a working/spare power supply circuit. CONSTITUTION:In case a DC stabilized power supply circuits PU1 applied mistakenly the overvoltage to a load 49 by some troubles among both circuits PU1 and PU2, a stabilizing part 4 detects this fault and functions to stop the output of the PU1. Thus the anode potential of a diode D41 drops suddenly and the cathode potential of the D41 drops gradually by the function of a capacitor C41. Thus the potential of the reverse input of a comparator Z21 in the spare circuit PU2 drops and the output of the comparator 21 is turned off. Then the PU2 functions to stabilize the both-terminal voltage V3 of the load 49, and the DC stabilized voltage is supplied to the load 49 to switch the PU2 to the working PU1. Thus it is possible to minimize the variance of the transient voltage in a switching mode to the load 49 by selecting properly the values of the C41 and resistances R1-R5, R21-R25, R41 and R42 respectively.

Title: Developer-carrying body
Inventor: OTA SHIGEO
IPC: F16C13/00
Filed: 1995-02-23
Abstract: PURPOSE: To improve the quality of image by limiting the arithmetic mean roughness and arithmetic mean spacing on the surface of a coated layer to respective specific regions. CONSTITUTION: The surface of the coated layer has the arithmetic mean roughness R ranging from 0.8μm to 2.5μm and the arithmetic mean spacing Sm ranging from 95μm to 150μm in a developer-carrying body for carrying a developer to a developing position where an electrostatic latent image is developed. In such a case, when the arithmetic mean roughness Ra on the coated layer surface of the developer carrying body is <0.8μm, the coated layer surface becomes too smooth and the quantity of the developer to be carried becomes small, thus lowering the image density. On the other hand, when the arithmetic means roughness Ra on the coated layer surface of the developer carrying body is >2.5μm, the quantity of the developer to be carried becomes too large nd the quantity of the developer to be electrified becomes small, thus lowering the image density.  Further, when the mean spacing Sm on the coated layer surface deviates from the range between 95μm and 150μm, the ghost of development is generated in the formed image, thus lowering the image quality.

Abstract: PURPOSE: To make a filled vessel being able to receive deforming force without hindrance when dropped by having structure that a rolling ring has the cross-sectional shape of the trapezoid, that its narrowest point is located at the bottom of a groove and increases the wall thickness toward the edge region, and that its axial end face ends in the plane of the bottom head of the vessel. CONSTITUTION: A support/transport ring 11 is integrally connected with a surrounding wall 4 of the vessel through a connection ring 15 connected to a horizontal contact face 13. The bottom of a groove between the connection ring 15 and surrounding wall portion 12 is disposed at a lower side of the horizontal face 13 with a separation. Also, the rolling ring 1 in the range of vessel bottom has the cross-sectional shape of trapezoid, its narrowest point is located at the bottom of the groove 2, forming a sort of hinges that can bend inward when a deforming force is produced sidewise, and wall thickness increases from the narrowest point toward the thick edge region. The axial end face 5 nearly ends at the plane of the bottom head 7 of the vessel, and the bottom head has shifted to the cylindrical surrounding wall 4 of the vessel through a conical wall portion 6.  Therefore, the rolling ring deformed absorbs bouncing energy produced in the dropped vessel.

Title: Welded joint excellent in fatigue strength and welding method therefor
Inventor: SETO KOJI
IPC: C22C37/04
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To produce a welded joint excellent in fatigue strength by specifying the chemical compsns. of a base metal and a weld metal and the welding conditions and limiting welding heat input. SOLUTION: By limiting the chemical compsns. of a base metal and a weld metal and welding heat input, the ferritic volume rates in the weld heat-affected zone and the weld metal heated to the temp. range of the Ac1 point to less than the m.p. are regulated to >=70%. Since ferrite is excellent in ductility (reduction of area), cracking generating resistance to the repetitions of local strains is also high, and, even in the case of the generation of fatigue cracking, it easily closes the cracking, thus its cracking propagating resistance is also high. Then, it has been found that the fatigue cracking propagating rate is slowest in the case of 30 to 300μm ferrite grain size. Moreover, the above welding heat input is limited to 3300 to 30000J/cm, and as the welding method, coating arc welding or gas shield arc welding is used.

Title: Power synthesizing circuit
Inventor: MARUYAMA TAKASHI
IPC: H01P5/19
Filed: 1979-03-26
Abstract: PURPOSE: To obtain a power synthesizing circuit which synthesizes high-frequency power by using resistors, whose one ends are grounded, to obtain a high resistance of a small distributed capacity where the impedance of the resistance connection point at the view from the ground is made high due to a circuit consitution.  
     CONSTITUTION: High-frequency power applied to input terminals 1∼3 are synthesized through distributed constant lines W 1 ∼W 3  at output terminal 4. Resistance R 1 ∼R 3  grounded through distributed constant lines 6∼8 having the electrical length of 1/4 wave length are connected to input terminals 1∼3, and one ends of distributed constant lines 6∼8 are collectively connected to connection point 9 in the side of input terminals 1∼3. Therefore, resistances R 1 ∼R 3  are equivalently placed between terminals 1 and 9, terminals 2 and 9, and terminals 3 and 9 respectively, and the impedance between connection point 9 and the ground becomes infinite. Since resistances R 1 ∼R 3  are grounded, the distributed capacity in the resistor can be corrected simply.

Title: Image forming device and process cartridge
Inventor: ISHIYAMA HARUMI
IPC: G03G21/00
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of electrification performance, which is caused by development carriers mixed into the magnetic particles of an electrifying means, by making magnetic restraining forces acting on the magnetic particles stronger than the magnetic restraining forces acting on the carriers, in a magnetic field generated at an electrifying position by a magnetic- field generation means. SOLUTION: On the electrified magnetic particles and the development carriers, magnetic restraining forces by which they tend to move toward an electrifying sleeve 3a due to the magnetic field of a magnet roller 3b and electrostatic forces by which they tent to stick to a photoreceptive drum 1 act. Here, by making differences between the magnetic restraining forces which do not change as the electrostatic forces but are always stable, at least the development carriers are ejected from an electrified magnetic brush during the use of the device. As a means for making the differences between the magnetic restraining forces, it is effective to give a magnetization difference to each particle. Thus, even when the electrostatic forces change, the magnetic restraining forces of the electrified magnetic particles are stronger than the magnetic restraining forces of the development carriers.
