Abstract: PURPOSE:To perform the correction of an off-track quantity in a wide range by performing an appropriate off-track operation at every data head by generating the off-track quantity and an off-track direction at every time set on a time table. CONSTITUTION:A timing means 16 sends an interruption signal to a control means 17 at every arrival of an off-track correction operating time. The control means 17, when receiving the interruption signal from the means 16, positions a servo head 6 at a prescribed position on a magnetic disk medium by issuing indication to a servo control means 18. Therefore, the data head 7 reads servo information recorded on a track on a data plane, and sends it to a position error detecting means 19, and the means 19 detects the off-track quantity and the off-track direction of the head 17, then, sends them to the means 17. The means 17 generates an offset quantity and an offset direction, and writes them on an offset table 14 at every data head. Next, the means 17 performs an offset operation for the head 6 during a time to the next time designated by the means 16 by using those quantity and direction.

Abstract: PROBLEM TO BE SOLVED: To eliminate generation of burrs by performing some extent of trimming deformation to the circular cut region of a cut material, and pushing back the trimming-deformed region in the reverse direction to separate the cut region. SOLUTION: A trimming rotor 17 is lowered by a trimming deformation cylinder, thereby performing trimming deformation for a circular region M to be cut of a material W to be cut to some extent.

Title: Transfer device and electrifier
Inventor: KURAMOTO SHINICHI
IPC: G03G15/16
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To obtain a transfer image of high image quality by providing a control electrode between a transfer electrode and a toner-image carrier, and limiting an area of ionization by discharge to a space between the transfer electrode and the control electrode. SOLUTION: The control electrode 12 is disposed in a position between the back of a transfer medium S and the transfer electrode 11, and a transfer voltage is applied to the transfer electrode 11. To the control electrode 12, a second power source 14 applies a control voltage producing potential which is medium between the potential of the transfer electrode 11 and the potential of the image carrier 1. As a result, between the transfer electrode 11 and control electrode 12, discharge occurs by a transfer voltage which is higher than a discharge start voltage, and the ionization area is formed, so that positive ions and electrons or negative ions are produced.  In the case, only such a low voltage as to cause no discharge is applied between the control electrode 12 and the image carrier 1 which is opposite it via the transfer medium S, therefore an ionization area is not formed and neither positive ions and electrons nor negative ions are produced between the control electrode 12 and the transfer medium S.

Title: Fur brush developing device
Inventor: HOSOYA MASAHIRO
IPC: G03G15/08
Filed: 1982-03-10
Abstract: PURPOSE:To improve the image quality and extend the life of a fur developing roll, by raising the fur of a recovering roll simultaneously with recovery of defectively charged toner particles due to the recovering roll. CONSTITUTION:Though toner particles, which have a prescribed charge quantity, stuck to a fur developing roll 24 are not scraped by a recovering roll 25, defectively charged toner particles are scraped. Therefore, a certain quantity of toner particles is always stuck to the fur developing roll 24, and a bias voltage is applied effectively, and toner particles are not accumulated. Defectively charged toner particles removed by the recovering roll 25 are carried to a supply roll 23 and are charged again. Since the fur is raised and laid repeatedly even if the developing process is performed continuously, the lowering of the image density and the ground fogging are not generated.

Title: Shield type loop gas resonator
Inventor: ONO MITSUHIRO
IPC: A61B10/00
Filed: 1988-02-19
Abstract: PURPOSE:To observe even a large object to be measured, by forming a loop by the inner conductor of a coaxial cable and providing a gap to the outer conductor of the leading end part thereof and supplying a microwave current to the inner conductor to generate a magnetic field outside the outer conductor. CONSTITUTION:A loop coil is formed by the inner conductor 2 of a coaxial cable and a shield conductor providing a gap to the leading end part of the loop is formed by an outer conductor 1. When a microwave current I1 flows to the surface of the inner conductor 2 from a power supply 4 in the direction shown by an arrow a b, a magnetic field is generated in the space between the loop and the shield and a current I2 flows to the inner surface of the shield so as to negate said magnetic field. The current I2 flows to the outer surface of the shield through the gap 3 as shown by arrows (i), (e). A magnetic field is generated by this current and, as a result, a magnetic field is generated around the shield. Since measurement is performed by utilizing the microwave magnetic field, the loop is moved and the arbitrary region of a large object to be measured can be measured. The leakage of an electric field to the object to be measured can be reduced by the shield effect of the outer conductor 1 and a high Q-value can be held.

Abstract: PROBLEM TO BE SOLVED: To prevent some charged particles from being directly struck against some electron emission elements by a method wherein supporting columns of insulation films narrower than a line width on an element substrate are arranged on the element substrate and a shielding plate is placed on the supporting columns to cover the electron emission elements. SOLUTION: A shielding plate 8 is provided on a thin film 3 including an electron emission part to cover an electron emission part in an image forming device. The height of the shielding plate 8 from a surface position at a substrate 9 is restricted by supporting columns 7 for an insulation film 5. The supporting columns 7 are formed with a width narrower than a width of X-directed wirings 6 on the X-direction wirings 6. As material for the shielding plate 8, it is preferable that it may be formed by metallic materials such as copper and nickel and their alloys. It is preferable that the electron emission element is of a surface conductive element.  With such an arrangement as above, it is possible to prevent the brightness from being reduced under a deteriorated state of the electron emission part and also to make a long life setting of an electron source as well as to improve a reliability in operation. Upon forming the supporting columns 7 through a thick film printing, the image forming device can be formed in a precise and easy manner.
