Patent JP-H03111762-A (JP)
Title: Speckle speed sensor
Inventor: MIYAZAKI HIDENORI
IPC: G01P3/80
Filed: 1989-09-26
Abstract: PURPOSE:To decrease speed measuring errors by forming the light receiving openings of photodetectors in a long shape which is longer in the direction crossing the moving direction of a speckle pattern at a right angle. CONSTITUTION:For example, light receiving openings 20 of two photodetectors are arranged along the moving direction (shown an arrow S) of a speckle pattern at an interval Xd (specified interval wider than the average speckle size), and the shape of the opening 20 is set in the long shape which is longer in the direction crossing the arrow S at a right angle. At this time, the correlation characteristic curve (correlation frequency distribution obtained with a sensor wherein delay time is expressed on the abscissa and correlation strength is expressed on the ordinate) has the symmetrical pattern on the right and left sides with a peak value as the center. Therefore, speed measuring errors are small. When the areas of the light receiving openings are equal, the shorter the length of the lateral side along the arrow S, the closer the pattern of the correlation characteristic curve to the symmetrical pattern on the right and left sides. In the sensor using a zero-crossing method, the speed measuring errors become small since the the number of the zero crossings becomes large.

Abstract: PROBLEM TO BE SOLVED: To cancel unnecessary radiation magnetic fields to be leaked from extension lines each other and reduce a leakage quantity by disposing extension lines of a horizontal deflection coil of a deflection yoke in proximity and flowing a current in the reverse direction. SOLUTION: Two extension lines 2c and 2d connecting connection terminals 3 and 4 of connector lead wires 5 and 6 and a lower horizontal deflection coil 1b are disposed in proximity, and currents flowing in respective extension lines are made to flow in the reverse directions. Thereby, unnecessary radiation magnetic fields 7 to be leaked from the deflection coil extension lines 2 are canceled each other, a super-low frequency magnetic field VLMF can be reduced. By stranding the extension wires 2 each in close to each other, the VLMF can be further reduced, and unnecessary radiation magnetic filed can be almost eliminated.

Title: Manufacture of container
Inventor: GERUDO SUTOFUERU
IPC: B29L22/00
Filed: 1990-09-21
Abstract: PURPOSE: To form an inner bag-like part without inducing an environmental contamination and to sufficiently uniformly form it by attaching a synthetic resin by spraying, then internally installing a container in a heat insulation furnace, and rotating it for a long time. CONSTITUTION: The container is formed by pressing, deep drawing or other method, then protective lacquer and primer are executed on an inner surface, an inner baglike part is formed by a synthetic resin coating of a polyolefin or a mixture containing the polyolefin. The container is then contained in a gas flowing furnace, and rotated for a long time. The material of the inner container is not concentrated at a specific position of an inner surface of the container by rotating, and air or solvent is not confined. Thus, the sufficiently uniform inner baglike part of a thickness of 80 to 120 micron is formed, and the polyolefin is almost completely burned, and hence an environmental contamination is not brought about.

IPC: G03F7/26
Filed: 1988-10-04
Abstract: PURPOSE:To obtain an image forming device having a rotating drum whose life is long without using a photoconductor by allowing toner which is encapsulated in and composed of a photosetting agent capable of being photoset with light having a certain wavelength and a coloring agent to adhere to the rotating drum whose surface is electrostatically charged and selectively making the surface of the rotating drum exposed and photoset. CONSTITUTION:When the rotating drum 11 rotates, the toner is uniformly and thinly stuck to the electrostatically charged surface thereof in an adhesion device 5. Thereafter, the toner on the rotating drum 11 is exposed with the light whose intensity is in inverse proportion to the various densities of an original 22 after receiving slit- exposure from the exposing device 20 in an exposure part 4. The toner which has been exposed in the exposure part 4 is pressurized to a recording paper by a transfer roller 12 to the heated with the rotation of the rotating drum 11. Since the toner is the microcapsule constitution encapsulating the photosetting agent which is photoset with the light having a certain wavelength and the coloring agent, the microcapsule of the toner which is not photoset is broken by the transfer roller 12 and the coloring agent included in the microcapsule colors the recording paper, thereby forming a printed image corresponding to the original 22.

Abstract: PURPOSE:To fit clutches positively by fixing permanent magnets rigidly to both clutches meshed through claws or teeth, and obtaining shaft rotating speed difference from the output of one magnetic force line detector so as to control the clutch connecting action on the basis of the obtained shaft rotating speed difference. CONSTITUTION:The lines of magnetic force from the permanent magnets M of a shaft 1 act upon a magnetic resistance element 6 constantly at all times, but the lines of magnetic force from the permanent magnets M of a shaft 2 change in the acting direction by the phase of the shaft 2 to the shaft 1. The resistance value of the magnetic resistance element 6 changes moment by moment in the case of the rotating speed of the shafts 1, 2 being different, and AC components are included in the voltage at both ends, but AC components vanish when the rotating speed coincides with each other. A judging circuit 7 generates output at the time of the AC components being within the fixed allowed range, and a control circuit 8 excites a solenoid 83 in the non-supplied state of an INHIBIT signal from a computer so that an internal gear 5 is displaced to link the shafts 1, 2 with each other. That is, both shafts are connected to each other without generating time delay other than mechanical delay without the way of the computer.

Abstract: PURPOSE:To simplify the structure and facilitate a change in a pressure medium distribution setting for the device in the caption, by having the pressure medium distribution device composed of a casing, a base, a rotor, and a rotor pressure. CONSTITUTION:Both of a pair of transmission holes 42a, 42b through a rotor 33 move on a plural number of grooves 39a-39c on a base 32, and therefore one rotation of the rotor 33 allows both of transmission holes 42a, 42b to be connected to the grooves 39a-39c circumferencially, in turn. Further, a pair of connecting holes 44, 45 in a rotor presser 34 are connected to a supply port 46 and a discharge port 47, respectively, on one side, and to a pair of transmission holes 42a, 42b via depression 43a, 43b, on the other side. Accordingly, either of a pair of the transmission holes 42a, 42b will be passage for the supply of a pressure medium, while the other will be a passage for its discharge. Therefore, one rotation of the rotor 33 allows the pressure medium to be supplied to each of the grooves 39a-39c on the base 32 via either one of both transmission holes 42a, 42b for its successive supply to pressure medium supply/discharge holes 38a-38c, in turn, and to be discharged simultaneously through the other in turn.
