Title: Magnetic spring having damping characteristics and vibration mechanism having the magnetic spring
Inventor: FUJITA YOSHINORI
IPC: F16F15/03
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic spring having zero or negative damping characteristics by utilizing permanent magnets, by changing a geometrical dimension between two permanent magnets separated from each other so as to converted into bounce, and setting output side bounce larger than input side bounce from the balanced position of two permanent magnets. SOLUTION: A magnetic spring having zero or negative damping characteristic is so formed that a geometrical dimension is changed by changing an opposed area of permanent magnets 2, 4. Then, when a certain input is applied to a base 6 so that the base 6 is moved toward a top plate 8, a magnet placing mount 18 is moved in a right direction along a linear way 16 by the inertia force of a balance weight 24. As a result, the opposed area of two permanent magnets 2, 4 is gradually increased, maximum bounce can be generated in a position where the permanent magnets 2, 4 are positioned near to each other most or in a position where this position is passed through, and also the base 6 is moved downward by the bounce. While the base 6 is reciprocated once against the top plate 8, the magnetic spring shows negative damping characteristic.

Title: Changing device for pickup direction of image pickup device
Inventor: KUMASAKA HIDEYUKI
IPC: H04N5/225
Filed: 1981-06-10
Abstract: PURPOSE:To realize a high-speed and optional change of the pickup direction, by fitting a reflector at the front of the lens of an image device, then turning the reflector without shifting the center point of the reflector. CONSTITUTION:When a pulse motor 6 is driven, a mirror support frame 3 turns toward an arrow A to the 1st fame body 4. As a result, a reflector 2 also turns toward the arrow A to the 2nd frame body 8. The body 4 turns toward an arrow B to the body 8 by driving a pulse motor 10. Thus the reflector 2 also turns toward the arrow B to the body 8. In this case, the rotary center axis l1 of the reflector 2 itself is orthogonal to the rotary center axis l2 of the body 4 on the reflecting surface of the reflector 2. Accordingly the point P, i.e., the intersection between the axes l1 and l2 has no splacement by the rotation of the reflector 2 or the body 4. Then a pickup direction changing device is set at the position of the reflector 2 so as to position the point P on the optical axis of a lens 1a. When the reflector 2 is turned toward the arrow A or B, the pickup direction of an image pickup device 1 is changed.

Title: Winker switch apparatus of autobicycle, etc.
Inventor: SHIBATA YASUO
IPC: B62J6/16
Filed: 1981-06-08
Abstract: PURPOSE:To make a driver clearly recognize that the position of a winker switch is in a lane change position, by increasing suitably and radically the operation load thereby making him exercise moderation before a right or left change-over position. CONSTITUTION:When a slider 23 is in the neutral position, an engaging head 58 is engaged resiliently with a neutral recess 42 in a moderation groove 41. When the knob 21 is moved, an edge 46 situated in the direction opposite to the direction of the movement of the knob 21 will abut on the engaging head 58, and therefore the resistance increases so that the operation load is radically increased to a prescribed value. When the edge 46 goes beyond the engaging head 58, the operation load will be decreased, and when the knob 21 is moved further to the right, the engaging head 58 will abut on a wall 47, and the resistance will increase radically and substantially. If in this position the operation load is released, the slider 23 will be returned to the neutral position, but if a further operation load is added, the engaging head 58 will go beyond the wall 47, and will be engaged with a support recess 43 or 44.

Title: Open/close system for sweeping material collecting valve in blaster
Inventor: HAMADA MASARU
IPC: B24C9/00
Filed: 1983-05-19
Abstract: PURPOSE:To collect sweeping material reliably into a blast tank by pressure contacting/releasing a limiting valve forcefully against a suction port communicating with a suction system. CONSTITUTION:In order to transfer the sweeping material into a blast tank 1, a release valve 11 is opened to return the interior of tank 1 to the atmospheric pressure while compressed air is pressure fed through a supply port 64 in an operating system 6 into the cylinder 62 to push down the piston 61 against a spring 60 thus to pressure contact a limiting valve 5 against a valve seat 36 and to temporarily interrupt a colletion tank 3 from a suction system 2. The interior of the tank 3 is brought to the atmospheric pressure through a collection hose to eliminate pressure difference against the tank 1. Consequently a valve body 4 choking a communicating port 10 is separated from said port 10 by the weight of sweeping material thus to flow the sweeping material into the tank 1. Thereafter the release valve 11 will close and the valve body 4 is blown up by the compressed air through an air tube 14 to the communication port 10 and pressure contact thus to increase the pressure in the tank 1 and to enable blasting work.

IPC: F25B41/06
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce a refrigerant passage sound being generated in the expansion valve of a refrigerant being provided in air-conditioning equipment. SOLUTION: In an expansion valve 10', a first passage 32 where a high- pressure refrigerant flows into a valve body 30 from a receiver 6 is formed by cutting matching, and a space 35a for constituting a valve room along an axial direction from the bottom part of the valve body 30 formed at the lower portion of the valve body 30 by a passage 33. The passage 33 and the first passage 32 for constituting the space 35a are formed while they interfere each other when they are formed and constitute a restrictor part 323 at the interference part.  More specifically, in the first passage 32, the diameter is formed so that the size of the sectional area of the passage gradually becomes smaller tin the direction of the valve room, and the passage 33 where the valve room is formed is allowed to interfere with the first passage of the sectional area of the diameter, this constituting the restrictor part 323. The restrictor part 323 is formed at a sectional area with a diameter being equivalent to approximately 3 mm. With the configuration, air bubbles mixed into a liquid phase refrigerant is made fine and a refrigerant passage sound is reduced.

Abstract: PURPOSE:To discriminate the similar characters from the crossing frequencies between the character strokes and a fixed angle, by giving vertical and horizontal scans to each point of a background part after reducing the number of candidate character types. CONSTITUTION:The number of candidate character types is reduced by an existing method. For these character types, both vertical and horizontal scans are carried out from the points showing a background. When the vertical and horizontal scans are given from a point P, the crossing frequencies between the strokes and scanning lines with a fixed angle are referred to as (a) and (b) as well as (c) and (d). Therefore a=1, b=4, c=0 and d=1 are satisfied for the point P in the figure (i). While a=4, b=1, c=3 and d=1 are satisfied for a point Q. As a result, the feature information obtained to perform discrimination among similar characters.
