Title: Image forming device
Inventor: ATSUMI TETSUYA
IPC: G03G21/00
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent a memory due to an electric charge injection to an image carrier, at the time of passing the tailing end of a recording material, in the transfer time by a contact electrifying method, and to prevent an image defect in a line state by maintaining a rise of the transfer current flow at the leading end of the recording material. SOLUTION: At the same time when the leading end of recording material reaches a transfer position, ON signal of the control for instructing to supply the transfer current of +15 μA is outputted to a transfer brush charging device from a CPU to a transfer power source. At the same time when the trailing end of the recording material that the image is transferred thereon reaches the transfer position, the output from CPU is switched to the ON signal for supplying the current of -5 μA, that is to apply the maximum voltage for the transfer power source possible to apply a voltage with a polarity opposite to the transfer voltage, to accelerate the rise-up of the transfer current for the trailing end to pass through, and to prevent the positive charge from being injected to the photosensitive drum. After the trailing end is permitted pass through the transfer position, in order to secure the immediate rise up of the transfer current at the leading end of recording material, the device outputs the ON signal to make the current 0 μA for the non-transferring time.

Title: Thickness measuring apparatus for sheetlike material
Inventor: SAITO YUTAKA
IPC: B65H7/02
Filed: 1994-03-16
Abstract: PURPOSE:To prevent breakage during the measuring of the thickness of a thin sheet by arranging a flow regulating valve between a three-way changeover valve and a tank cap to act as resistor of an flow rate of air in the introduction thereof and as non-resistor in the discharging thereof. CONSTITUTION:A flow regulating valve 30 is so arranged between a three-way solenoid valve 12 and a tank cap 2 to have an air flow choking mechanism E and a one-way passage mechanism F which is adapted to close to the flow of air from one way and pose no resistance to the flow of air from the opposite way. In the measurement of the thickness of a sheetlike matter (paper) C thick relatively (about 40-50mum), the mechanism E is opened fully to accelerate the speed of a conductor target 7 when contacting the paper C, for example, to 0.1sec. By the contrary, in the measurement of the thickness (about 20mum) thin relatively, the mechanism E is throttled to slow the lowering speed of the target 7 to about 0.5sec. by regulating the amount of the air flowing into the cap 2. When the paper C is separated from the target 7, the solenoid valve 12 is turned OFF to make the air in the cap 2 flow out to the discharge side (k) of the valve 12 from the mechanism F.

Title: Magnetic disk device and its assembling method
Inventor: SUZUKI MASAMI
IPC: G11B25/04
Filed: 1989-02-27
Abstract: PURPOSE:To realize the high rotating accuracy of a rotary part which drives a magnetic disk by supporting a bearing with a cabinet on which a through hole not coming into contact with a rotary shaft is formed via a bearing holding device to support the bearing with point contact with high degree of freedom. CONSTITUTION:The bearing 20 is inserted to a terminal part where the flange part 14a of the rotary shaft 14 is provided. The inner wheel 20a of the bearing 20 is provided with the same coefficient of linear expansion as that of the rotary shaft 14, and also, the inner periphery of a shaft through hole 20d is processed with high accuracy, therefore, the bearing 20 can be loaded on the rotary shaft 14 with high fitting accuracy. Next, the rotary shaft 14 is inserted to the through hole 10a of a base 10, and the outer wheel 20c of the bearing 20 already loaded is brought into contact with the wall plane of the base. At this time, since the minor diameter of the through hole 10a of the base 10 is formed sufficiently larger than the major diameter of the inner terminal part of the inner wheel 20a of the bearing 20, no constraint in the motion of the rotary shaft 14 in a radial direction occurs. After that, the clamp 21a of the bearing holding device 21 is fixed on the base 10 with a fixing screw 21b as pressing so as to be brought into contact at two outer peripheral points 20e and 20f of the outer wheel 20c of the beating 20.

Title: Micro-strip antenna and method for adjusting its resonance frequency
Inventor: OKADO HIRONORI
IPC: H01Q13/10
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a micro-strip antenna small in size and excellent in directional gain. SOLUTION: A ground plate 7 and a feeder element 8 are laminated respectively on the backside and surface of a dielectric substrate 6. A parasitic element 10 is oppositely provided above the feeder element 8 through a gap 9. A slot hole 11 and a slit are provided in the center area of the parasitic element 10. When current (i) is excited on the parasitic element 10 with the connection of the feeder element 8 and the parasitic element 10, current (i) detours so that it avoids the slot hole 11 and the slit. Thus, a current route becomes long and the parasitic element 10 can be miniaturized. A back lobe becomes small and the micro-strip antenna excellent in directional gain can be realized. Then, a resonance frequency can easily be controlled by controlling the sizes of the slot hole 11 and the slit and the size of the feeder element 8.

Filed: 1985-03-11
Abstract: PURPOSE:To obtain a high purity antibody free from antibody non-specific to protein A, by contacting protein A with an antibody other than anti-protein A antibody to bond said antibody to the Fc acceptive group of protein A. CONSTITUTION:At first, protein A is contacted with an antibody other than an anti-protein A antibody and said antibody is bonded to the Fc acceptive group of protein A. Next, this antibody is fixed to the Fc acceptive group by a fixing agent (e.g., glutaraldehyde) and this protein A is contacted with a solution containing an anti-protein A antibody to bond the anti-protein A antibody to the antigenic determinant of protein A. After this protein A is washed, an eluent (e.g., a glycine-hydrochloric acid buffer solution) is used to elute the anti-protein A antibody bonded to the antigenic determinant. An antibody non-specific to the protein A present in the state mixed with the anti- protein A antibody is not present in thus obtained anti-protein A antibody even after the adsorption of protein A by the Fc acceptive group and elution.

IPC: G09G3/36
Filed: 1989-03-01
Abstract: PURPOSE:To extend a drivable area to easily display a picture throughout a panel by controlling the degree of the AC stabilized state with an external impressed pulse. CONSTITUTION:A no-electric field state 15 is set in a first period 11 at the time of selection, and a bipolar pulse 16 is impressed in the first period 13 at the time of half-selection. Meanwhile, a pulse 17 higher than a prescribed threshold is impressed in a second period 12 at the time of selection, and a pulse 18 lower than the threshold is impressed in the second period 14 at the time of half-selection. The bipolar pulse to increase the degree of the AC stabilized state is always added in the first half part of the half-selection pulse which should not be inverted, and the weak bipolar pulse to reduce the degree of the AC stabilized state or the pause period of the no-electric field state is added to the selection pulse to be inverted. Thus, the drivable area of the ferroelectric liquid crystal panel is extended to always display a picture throughout even at the time of the change of temperature or the like.
