Title: Movable mirror unit
Inventor: ARAKI YOSHITSUGU
IPC: G11B7/09
Filed: 1979-07-28
Abstract: PURPOSE: To improve the performance of holding relative positions of washers and fulcrums of a video disk player by causing the contact area between the fulcrums and washers in the fulcrum direction not to increase in the direction of the turning axis of a mirror and then by linearly arraying the fulcrums in the direction of the rotating shaft of its vibration.  
     CONSTITUTION: As for movable mirror unit 1, conic pin fulcrum 3 and linear fulcrum 4 are fitted nearly in a line to fixation part 2 of the optical video disk player. On holding plate 6 of mirror 5, washer 7 of the linear concave part that corresponds to said pin fulcrum 3 and washer 8 of the linear concave part that corresponds to said linear fulcrum 4 are formed respectively over rotating shaft 9 of said mirror 5. Thus, this invention increases the contact area over the rotating shaft as much as possible and while relative positions of the fulcrums and washers are maintained, a centralized load is prevented, so that the holding performance of the holding part will be stable.

Abstract: PURPOSE:To extract a contour parallel to horizontal scanning lines of the subject by clamping a video signal to a pedestal level and then delaying it by one horizontal scanning line period, and comparing the delayed signal with the video signal after the pedestal clamping. CONSTITUTION:The contour extracting circuit for the subject consists of a pedestal clamping circuit 37, delay circuit 39, CCD video signal delay circuit 23, comparators 25, 26, 42, 47, etc. When signals Y, CP, etc., are inputted from a video camera and then the signal Y2 clamped to the pedestal level by the pedestal clamping circuit 37 is sent to the delay circuit 39 and delayed by one horizontal scanning line period, thereby extracting a vertical edge signal E3. A horizontal edge signal E8, on the other hand, is extracted through the CCD video signal delay circuit 23 and comparators 25 and 26. Consequently, vertical and horizontal contours of the subject are extracted by synthesizing both edge signals E3 and E8.

Abstract: PURPOSE: To prevent a shifter from biting into a sliding surface by a method wherein the outside diameter of the sliding surface between the shifter and a support ring is made larger than that of the boss portion of the gear.  
     CONSTITUTION: A small-diameterd gear 34 and a large-diametered gear 36 are rotatably supported on a driven shaft 22, and the gears 34, 36 are provided with claws 38, 40 in the shape of internal gear. Between the gears 34 and 36, a support ring 42 is spline-connected to the driven shaft 22. The outside diameter of the support ring 42 is larger than those of the bosses 44, 46 of the gears 34, 36.

IPC: F03D9/00
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To increase the generated power regardless of the change of the wind direction in a wind power generator which comprises a vane mounted in a space at a specific height from the ground as the motive power by mounting a guide plate for guiding the wind flowing in the space to a propeller, in the space from a lower end of the propeller of the vane to the ground. SOLUTION: A steel tower 3 is built on the ground surface 4, a propeller 1 is mounted on an apex of this steel tower 3, and a generator 2 is driven by the torque of the propeller 1. On this occasion, a guide plate 5 is mounted in a space S between a lower end T of the propeller 1 and the ground surface 4 in a state that it is supported by a strut 8, and the air flowing in the space S is guided to the propeller 1 by the guide plate 5. A front end 6 of this guide plate 5 is raised from the ground surface 4 by a length corresponding to a boundary layer δ1 of the ground, and a rear end 7 is lowered from a lower end T of the propeller 1 by a length corresponding to a boundary layer δ2 of the guide plate 5, whereby the low-speed component of the wind of both boundary layers δ1, δ2 can be prevented from guided.  Whereby the wind speed can be increased, and the generated power can be effectively increased.

Title: Local area network for rearrangement in case of line interruption and node failure
Inventor: HERRMANN CHRISTOPH
IPC: H04L12/70
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To rearrange a line network in a different aspect by making a node that detects a node failure and line interruption notify the default to all of other related nodes with a 1st kind of communication. SOLUTION: If inner ring connection between network nodes 34 and 35 fails, communication PI about a failure is detected by the node 35 which transmits to other line network nodes through both inner and outer rings, and the communication PI is transmitted (37 and 38) in the direction of the node 36 to the inner ring and in the direction of the node 34 to the outer ring. The node 34 which receives the communication PI performs description on a current table and evaluates the description. Though other network nodes separately evaluate the current table, evaluation in network nodes 33 and 36 does not perform any action as a result. In the node 34, a cell group on the inner ring is guided to the outer ring at that time and reaches a destination node through the outer ring in the place of the inner ring.

Abstract: PROBLEM TO BE SOLVED: To provide a linear polarization sharing device which suppresses the loss of transmission power, etc., can suppress the useless power consumption and can realized a low cost. SOLUTION: A 180 deg. hybrid 11 inputs an input signal given to a signal terminal 6 through a switching device 4 switched in accordance with a polarization direction and branches it into signals having either phase relation of a positive phase of a negative phase in accordance with a set polarization direction. Amplifiers 10a and 10b input and amplify a signal from the hybrid 11 and respectively energize probes 8 and 9. As a result, the probes 8 and 9 generate mutually orthogonal electromagnetic wave components. The electromagnetic wave components are combined in a primary radiator 1 and radiated as a transmission wave of a vertical or horizontal polarization wave to air. Here, the probes 8 and 9 are attached to the radiator 1 at a prescribed installation angle so that the combined electromagnetic waves can be a horizontal or vertical polarization wave.

Abstract: PURPOSE:To increase the peel resistance or a coating material by forming fine projected claws having a trapezoidal or arcuate head with a depth of a specific ratio to a coating film thickness at densities more than a prescribed density on one or both faces of a steel or a stainless steel sheet having a specific thickness. CONSTITUTION:For example, fine projected claws are formed on one or both faces of a 0.08-0.8 mm thick stainless steel sheet for cylinder head gaskets for automobile engine by use of a tool with fine cutting edges or a roll; the height of the claws are uniformized by a flat roll to form the claws having a trapezoidal or arcuate head whose height is 40-70% of the thickness of a heat resistant elastic coating film to be adhered and the number of the claws is formed to be >=1000 per 1 cm<2>. By applying the coating material to the surface, the peel resistance is increased by adhesion. The performance and service life as gaskets are improved because the coating material is not broken through to the stainless sheet having adverse adhesion and the tight adhesion is increased.
