Inventor: VINCENT ALAN HENRY
IPC: F16F15/02
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for reducing the vibration in a helicopter having small parasitic mass, which may not accidentally damage the accelerometer and its associating wirings, and absorbs the vibration at its source or in vicinity thereof. SOLUTION: A helicopter structure 10 comprises a plurality of actuators connected between a body 12 which may perform relative motion with an excitation frequency, and a frame 17. The actuators are continuously vibrates by a source 20 of liquid pressurized fluid at a frequency substantially equivalent to the excitation frequency. A sensor 21 mounted at a given position on a rotor blade generates signal indicating dynamic change in a predetermined position, a computer 22 processes this signal to generate output signal in order to control the magnitude and the phase of the additional power by the actuators, and to change the characteristics of the magnitude and the size of the additional force so as to reduce total vibration level of the body by compensating for the changes of the dynamic characteristics of the rotating system.

Title: Composite type magnetic head for magnetic disk device
Inventor: HAYAKAWA YUICHI
IPC: G11B5/48
Filed: 1988-12-06
Abstract: PURPOSE:To prevent mutual interference between two gaps which are not arranged on the same straight line and, at the same time, to reduce the azimuth loss of the two gaps by making the azimuth angles of the two gaps coincident with each other. CONSTITUTION:The azimuth angle of a gap 14 when the gap 14 is positioned above the N-th track of a magnetic disk is the angle theta 1 between the straight line DG connecting the center D of the gap 14 and the center G of the magnetic disk and the straight line connecting both ends EF of the gap 14. The azimuth angle of another gap 17 when the gap is positioned above the N-th track is the angle theta 2 between the straight line JG connecting the center J of the gap 17 and the center G of the magnetic disk and the straight line connecting both ends KL of the gap 17. The two gaps are separated from each other by a dis tance at which they do not interfere with each other by not arranging them on the same line and the two gaps are inclined against each other so that their azimuth angles can coincide with each other at the prescribed track position. Therefore, mutual interference between the two gaps can be prevented and the azimuth loss can be minimized.

IPC: F28B1/02
Filed: 1993-12-08
Abstract: PURPOSE:To obtain a condenser capable of improving an operation rate and reliability of a turbogenerator by forming a hardened layer by plating on outer peripheral surfaces of cooling tubes disposed along the outermost periphery of a tube bundle of cooling tubes and preventing erosion from being generated by impingement of turbine exhaust steam and water droplets included therein. CONSTITUTION:Cooling tubes 6a having a hardened layer 12 applied by plating onto the outer peripheral surfaces of the cooling tubes are disposed at the outermost peripheral portion of a tube bundle of cooling tubes 6. The cooling tube 6a has the hardened layer 12 formed by plating on the outer peripheral surface of the cooling tube 6 made of pure titanium, except parts 10, 11 near both the ends of the cooling tube, which are expanded for fixing the cooling tube to tube plates. The hardened layer 12 is formed by electrically plating the cooling tube 6 made of pure titanium in a nickel plating tank, in which nickel is mixed with particles of silicon carbide(SiC) having 1 micron or thereabout in particle size at a ratio of 50 to 200g/l. With this arrangement, a condenser can show not only resistance to corrosion resulting from seawater side but also sufficient resistance to erosion even in the case where steam impinges against the cooling tubes at a high speed.

Title: Dynamic image decoder
Inventor: ENDO YUKIO
IPC: H04N19/61
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in an image by obtaining a contour of an area with a motion of an image from a difference between frames of a reproduced image and avoiding application of 2-dimension spatial filter processing to the contour so as to prevent the contour of the image from being fogged. SOLUTION: A subtractor 13 receives a dynamic image signal 21 being an output of a decoder 11 and a dynamic image signal 22 being an output of a frame memory 12 and obtains a difference between both the signals. The dynamic image signals 21, 22 are the same dynamic image signal but the moving image signal 22 is delayed by 1 frame than the dynamic image signal 21. Thus, whether or not an image generated by the dynamic image signals 21, 22 is an image having a motion is decided. A spatial filter 16 applies 2-dimension spatial filter processing only to dynamic picture elements excluding the contour of the dynamic image based on a control signal 25 from a spatial filter control circuit 15 to eliminate a quantization noise such as mosquito noise included in the reproduced image.

Abstract: PROBLEM TO BE SOLVED: To make an image forming device possible to attain such as reduction in running cost, by minimizing a consumption of toner by saving excessive toner sticking to the latent image on a photoreceptor, in addition to satisfying the image quality required by a user. SOLUTION: With this image forming device, since reflection density of the output image is saturated at a point that the development contrast is high, the image density is observed as the same to a user, regardless of the toner quantity on the image beyond that, as a result the toner wasted uselessly. Patches are formed on a photosensitive drum with the density from A0H to FFH, measured by a sensor. Then, density gradient between patches is taken, and inclination of the gradient (second differential of density) is taken in addition thereto, and moreover inclination between the patch potential and DC component of developing bias becomes to 0 for the second time is defined as the optimum development contrast.  At this time, since the development DC component is unchanging, the development contrast is controlled by the potential on the maximum image part at the time of forming the latent image on the photosensitive drum (maximum light quantity of laser). Since the second differential value becomes 0 at E0H, the E0H is regarded as the maximum light quantity.
