Title: Electromagnetic lens actuator for driving optical disk
Inventor: MAATEIN MATSUKIYASURIN
IPC: G11B7/09
Filed: 1994-01-12
Abstract: PURPOSE: To provide an actuator having component parts of very high stiffness and light in weight by using a fine position setting level actuator. CONSTITUTION: A motor M of a disk drive 1 rotates a spindle S and a disk D at a comparatively high speed. A position setting actuator A sets the position of a carriage C on a position that a laser beam B is projected on a specified track or its neighborfood of a disk surface 7 on which information is to be read, recorded or erased. The light beam B is exactly positioned on a track by moving a lens 16 in the radial direction to the carriage C by means of a fine position setting actuator 10 and the lens 16 is positioned at a desired vertical distance from the disk surface 7 so as to converge the beam B. In the actuator 10, more than half of coils of a coil assembly has an active area, a current in the area interacts with a first magnetic field and exerts force on a lens part.

Title: Elimination of adhering ammonium salt from air preheater
Inventor: AOKI NOBUO
IPC: F23J3/00
Filed: 1978-01-12
Abstract: PURPOSE: To prevent the temperature decrease of the heat conducting part of the flow passages of air preheater into the concentric circles of which center is the axis of rotation and successively closing the sides which touch the air of the flow passages.  
     CONSTITUTION: By independently and successively shutting off the air flow in the parts of the divided flow passages a-d on the air side, head conductng part heated at the boiler exhaust gas side I is returned to the boiler exhaust gas side I without being cooled at the air side II, and the appropriate high temperature condition can be continuously maintained. Therefore, adhering ammonium salt on heat conducting part can be resolved and eliminated by controlling the maintaining time of high temperature condition in accordance with the gas temperature. Since the boiler exhaust gas is around 350°C, adhering (NH 4 ) 2 SO 4 , NH 4 HSO 4  can be resolved in comparatively short period of time.

Title: Device for removing foreign matter sticking to insulative sheets
Inventor: MATSUMOTO YOICHI
IPC: B41F23/00
Filed: 1986-01-10
Abstract: PURPOSE:To absorb and remove foreign matter sticking to the surface of an insulative sheet continuously with high efficiency by providing an insulated roller of high dielectric constant which rotates in contact with the insulative sheet. CONSTITUTION:When a corona discharge electrode 3 is energized by a DC high tension source 8 together with each insulative roller 2 and then is charged in homopolarity to printing paper (a), each insulative roller 2 of high dielectric constant will be negatively charged in reversed polarity to the printing paper (a). At the same time, corona discharge will occur from the corona discharge electrode 3 to each insulative roller 2, generating an ion wind. Then each insulative roller 2 will contact the printing paper (a) and rotate in an arrow direction. Foreign matter a' sticking to the surface of the printing paper (a) is allowed to stick to the roller 2 physically under an applied pressure and is further strongly adsorbed by the roller assisted by a static adhesion force. Thus foreign matter is removed from the surface of the printing paper (a) to be carried into a casing 1 where it becomes homopolar. After this, the foreign matter is blown away by the ion wind (f) and separated into each tray 4.

Title: Toner replenishing device
Inventor: IMANISHI MASAHIRO
IPC: G03G15/08
Filed: 1990-01-09
Abstract: PURPOSE:To prevent toner from flocculating by sending gas in a hopper container from the outside of this device. CONSTITUTION:A pipe 3 for allowing air to flow in the hopper container 1 is connected to the container 1 through a filter 4. A screw 2 is always in a state where it is covered with the toner. As soon as the screw 2 rotates, the air passes through the pipe 3 to be sent to the container 1 from an air blower or an air compressor through the filter 4 and it is abutted on a shielding plate 5 and blown against the screw 2. Since the pipe 3 is faced to a screw carrier direction, the toner in a flexible pipe 6 is pushed to the carrier direction and smoothly conveyed. Thus, the generation of the mass of toner at the time of conveying the toner by the screw 2 is reduced.

Title: Selecting circuit of intermediate value
Inventor: ARITA SETSUO
IPC: G05B7/02
Filed: 1983-01-12
Abstract: PURPOSE:To always attain selection of a signal having an intermediate level among three analog signals by setting the output current of a constant current circuit within a high value (low value) selecting circuit of an input stage at a level double as much as the output current of a constant current circuit within a low (high) value selecting circuit of an output stage. CONSTITUTION:If E1>E2>E3 is satisfied among three signals E1-E3 supplied to terminals 4-6 respectively, the signals shown as E1-VF, E2-VF and E1-VF are delivered to the outputs of high value selecting circuits 21-23 respectively (VF: forward drop voltage of diode) through constant current circuits 17-19. These three circuits deliver the currents double as much as that of a constant current circuit 20. Therefore the currents of the same level as those supplied to diodes 8-13 flow to diodes 14-16 if the output signals of the circuits 21-23 are supplied to the cathodes of the diodes 14-16 of a low value selecting circuit 24. As a result, the circuit 24 delivers only the voltage (E2-VF+VF), i.e. E2 which is higher than the voltage of a low level by an amount of voltage equal to the voltage lowered by the diode of the high value selecting circuit among the input signals to a terminal 7.

Title: Proportional seat valve of back pressure compensation type
Inventor: TANAKA HIROHISA
IPC: F16K31/122
Filed: 1990-01-11
Abstract: PURPOSE:To eliminate influence of external turbulence by furnishing a seat valve having a feedback slit at its outlet with a stem receiving the pressure with the same area, and connecting the oil pressure chamber and the outlet from a control pilot valve to a tank. CONSTITUTION:A stem 3 is furnished at the outlet 5b from a seat valve 1A, and the section area of its flange part 4 is given the same area as the outlet pressure-receiving surface 30. The lead-in hole 5d of the oil pressure chamber 6A at the flange part 4 and the leadout hole 20b of a control pilot valve 20 are connected with a tank T through an oil pipe l2. When the load 25 varies and external turbulence occurs, a varying pressure is generated at the outlet 5b. As the output pressure-receiving area 30 and flange part 4 have the same area, this varying pressure is divided into two and impressed oppositely. Accord ingly the varying pressure (back pressure) is canceled, and no movement of seat valve 1A will be generated. Thus back pressure compensation is made in simple structure.

Title: Production of antireflection plate
Inventor: KOBAYASHI KENGO
IPC: B29D11/00
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an antireflection plate capable of securely forming non-reflection light shielding films only on the perpendicular surfaces exclusive of the slopes of the projecting lines of an antireflection plate formed with the many fine parallel projecting lines of a saw tooth shape in section on the front surface of a transparent plate. SOLUTION: A photosensitive coating material 5 for the non-reflection light shielding films is applied on the front surface of the transparent plate 1 formed with the many fine parallel projecting lines 2 of the saw tooth shape in section on the front surface. The front surface is irradiated with the parallel rays approximately parallel with the slopes 4 of the projecting lines 2 to sensitize and cure the photosensitive coating material 5 on the perpendicular surfaces 3 of the projecting lines 2. The irradiation time or illuminance of the light is adjusted to shorten the irradiation time or weaken the illuminance to the extent that the light reflected from the perpendicular surfaces 3 falls onto the slopes 4 and does cure the photosensitive coating material 5 on the slopes 4.  As a result, only the photosensitive coating material 5 on the perpendicular surfaces 3 is incompletely sensitized and cured. Next, the transparent plate 1 is washed and the unsensitized coating material parts on the slopes of the projecting lines are removed to allow the photosensitive coating material to remain on the perpendicular surfaces 3. Next, the photosensitive coating material 5 on the perpendicular surfaces 3 of the projecting lines is completely cured by irradiation the transparent material again with the light or putting the transparent plate into a thermostatic chamber and heating the plate at a prescribed temp.
