Title: Photographic printer
Inventor: NAKAMURA HIROAKI
IPC: G03B27/70
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To easily and accurately perform dodging in a photographic printer where photographic paper is housed in the body of the title printer. SOLUTION: Illuminating light whose color balance and intensity are adjusted by a dimmer 11 illuminates a digital micromirror device 2. In the device 2, micromirrors very small in size and freely swingable are arranged in a matrix state, and spot light is reflected toward a lens 20 or a light absorption plate 25 in accordance with the tilt angle of the micromirror. In monitoring, the spot light reflected by all the micromirrors goes toward the lens 20, so that the respective parts of a frame are dividedly illuminated with the spot light. The micromirror illuminating a range where dodging is not performed continuously reflects the spot light toward the lens 20 in the midst of printing.  The micromirror illuminating a dodging range reflects the spot light toward the lens 20 at the beginning of printing but reflects the spot light toward the light absorption plate 25 because the tilt is changed in the midst of printing. Since illumination is stopped in a dodging range, projection to the photographic paper 23 is finished in the midst of printing. Exposure is reduced in the dodging range, so that the density of a printed photograph is lowered.

Title: Micro-rotor and its manufacture
Inventor: UKITA HIROO
IPC: C23F1/00
Filed: 1992-11-10
Abstract: PURPOSE:To generate a high speed rotating of a micro-rotor when it is irradiated with a laser beam, etc., by installing paddles on the side of a post, and eliminating the existence of any symmetrical plane parallel with the axis of the micro-rotor. CONSTITUTION:As a post 3 irradiated with a laser beam 8 is in columnar form having a rotational symmetrical axis, the post 3 is trapped so that the upper part is positioned at the focus 9a, and the axis of a micro-rotor 1 becomes parallel with the optical axis of the laser beam 8. Because paddles 2 formed on the side of the post 3 are asymmetrical about the rotational axis, the light pressure applied to the paddles 2 to be irradiated with the laser beam spreading from the focus does not nullify in the total in case the post 3 is trapped at the focus of the laser beam. The total of the light pressure applied to the curved surface of the paddle 2 in the form of a circular arc is greater than the total of the light pressure applied to the mating plane because the area of the curved surface of the paddle 2 is greater than the area of the mating plane, and a torque is generated in the direction of the curved surface, and the micro-rotor 1 rotates.

IPC: G11B5/85
Filed: 1991-12-09
Abstract: PURPOSE:To simply manufacture a finely patterned magnetized film by employing a focused ion beam induction depositing method for depositing in a gas atmosphere including ferromagnetic metal while scanning a beam on a board. CONSTITUTION:Ions emitted from a liquid metal ion source 1 are focused by an electrostatic lens 2 to form a beam on a board 4. Gas of compound including metal to become ferromagnetic material is supplied by a nozzle 9 to the surface of a sample to form a gas atmosphere of a high pressure locally on the surface of the sample. The ions heated to 10keV of energy number are scanned in a desired pattern state by a deflector 3, gas absorbed to the surface of the sample is decomposed, and metal in the gas is deposited. A coil 6 is wound on a sample base 5 of an integrated ion beam unit so that the board is disposed in a uniform magnetic field. Thus, a finely magnetized film can be simply formed, and a time required for manufacturing and its cost can be reduced. Further, performance of an integrated circuit in which the film is applied can be enhanced.

SOLUTION: Presence/absence of the stepping action of an accelerator pedal 36 by a driver is judged, and if the action is present, the stepping quantity is recognized by an electronic control device through an accelerator pedal switch 46. Then, presence/absence of the electronic control operation is judged, and if the electronic control operation is present, the mode is set to the combination mode of the mechanical type and the electronic type. The speed limit signal to be transmitted from the speed limit device installed on a road is received by radio, and if the traveling speed of the vehicle exceeds the speed limit, the opening angle of a throttle valve 32 is forcibly reduced by a motor 44 to reduce the speed for the safe drive. However, if the vehicle speed is within the speed limit, the regular traveling condition is maintained.

IPC: B32B25/10
Filed: 1987-12-21
Abstract: PURPOSE:To obtain a lining material for a conduit having vibration relieving property, external pressure retention and pressure resistance, and suitable diameter expandability by forming a hermetically sealing layer of rubber or synthetic resin on the outer face of a cylindrical woven fabric made by weaving warps and wafts in a cylindrical shape, disposing as wefts highly rigid yarns in a substantially oriented state inside the cylindrical woven fabric, and engaging the woven fabric in a slackened state. CONSTITUTION:In a lining material 1, a hermetically sealing layer 3 of rubber or synthetic resin is formed on the outer face of an outer cylindrical woven fabric 2, and an inner cylindrical woven fabric 4 is engaged within the fabric 2. The fabric 2 is formed by weaving warps 5 and wefts 6 in a cylindrical shape, and the layer 3 is formed on the outer face of the fabric 2. Since the fabric 4 having the wefts 8 employing highly rigid yarns is slackened, the diameter expansion of the fabric 2 is not disturbed by the rigid yarns, the lining material is suitably diameter-expanded by fluid pressure, and press-bonded to the inner face of a conduit in a state that the rigid yarns are substantially elongated. Accordingly, a pipe of a FRP structure reinforced with the rigid yarns with sufficient thickness is formed inside the conduit.

IPC: G03G21/00
Filed: 1990-11-26
Abstract: PURPOSE:To prevent the toner removed from the outer circumferential surface of a photosensitive drum from being scattered on the circumference by receiving a cleaning tool making sliding contact with the outer circumferential surface of the drum in a cylindrical body, and sucking the cylindrical body inner part by a sucking means. CONSTITUTION:A photosensitive drum 10 to be cleaned is vertically held by a drum support means 20. A cleaning tool 41 in a cylindrical body 44 is rotated by a motor 65, and a suction pump 53 connected to the cylindrical body 44 is driven.
