Title: Differential device
Inventor: MIMURA KENJI
IPC: F16H48/40
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a differential device capable of attaining a differential limit force which is always stable even during a low speed rotation. SOLUTION: As each of bevel gears 3 generates a difference in rotation from each other, each of rollers 7 is rolled while it is being press contacted with a pressure ring 5 and a pressure plate 6 and then a cage 7a is also rotated in following this rolling. At this time, each of the rollers 7 is rolled along a rotating track of the pressure plate 6 while being restricted by the cage 7a against a tendency that it is rolled in the direction slanted by a predetermined angle in respect to the rotating track of the pressure plate 6, resulting in that a frictional force is generated between each of the rollers 7 and its contact surface and the frictional force becomes a resistance to cause a differential motion to be restricted.  At this time, since each of the rollers generates a slipping friction while being rolled, a static friction is not generated and a stable frictional force caused by dynamic friction can always be attained.

Abstract: PURPOSE: To provide a compact measuring machine which can measure the inner diameter and the like of art object to be measured accurately and at high response speed by converting movement of a probe contacting with the object to variation of optical path length through a tapered face, and detecting it by means of the detecting probe of an optical fiber type laser interferometer. CONSTITUTION: Probes 16, 18 are moved in parallel by a linear guide 14, and extended by springs 20, 21 until they are brought in contact with the inner wall of a tube W. When the inner diameter of the tube W is larger than a reference inner diameter, the probe 16 is left, the probe 18 is right, respectively moved, a tapered member 22 is slided right downward along a tapered face 16a, and a specular face 22b is moved downward in parallel. Meanwhile, when the inner diameter is smaller than the reference inner diameter, the specular face 22b is pushed upward. This displacement quantity is detected by means of the detecting probe 42 of an optical fiber type laser interferometer 40.  The moved quantity of the specular face 22b is expressed to be contracted by tanϕ times due to the inclination 4 of the tapered faces 16a, 22a, difference against the reference inner diameter is obtaind to be spread by 1/tanϕ, and hence accurate measurement can be performed.

Title: Controlling dam for debris flow
Inventor: NAKAJIMA KAZUYOSHI
IPC: E02B7/04
Filed: 1982-06-01
Abstract: PURPOSE:To suppress the impaction acting on a dam body by a method in which the upstream side of the lattice formed dam is inclined upwards toward the downstream side of the dam in such a way as to permit huge rocks in debris flow to ride on it. CONSTITUTION:A dam 1 is constituted of wings 2 made of concrete and a steel lattice-work 3 provided between the wings 2, and the steel lattice-work 3 is inclined 9 upwards toward the downstream side of the dam 1. Thus, the debris flow is directed downwards through an opening 8 and huge sizes of rocks are ridden on the upwardly inclined part 9 by their potential energy E1. Therefore, impaction acting on the dam body is reduced by as much as P1 or the potential energy, the sliding and turning movements of huge sizes of rocks are suppressed, and the falling moment is also greatly limited.

Abstract: PURPOSE:To cut a pattern correctly by providing a spindle positioning means and performing alignment of the center of a tool at the center position of circuit cutting. CONSTITUTION:A spindle positioning means 11 is provided to perform positioning of spindles for pattern cutting and throughhole cutting respectively. A light source 1102 for spot irradiation is made to move by controlling the drive of a spindle head moving means 4 with output signals from the spindle positioning means 11 so that the light source may irradiate the circuit cutting position of a printed board 5 and simultaneously, a TV camera 1101 may take images of the circuit cutting position. On the basis of an image where the center of the circuit cutting position is taken by the camera 1101 out of the images taken by the above mentioned steps, the center of the circuit cutting position is detected by a control means 1105 and the drive control of the spindle head moving means 4 is performed. Then, even though there are errors at a circuit position, the center of the tool can be aligned at the center of the circuit position. Pattern cutting superior in quality is thus performed.

Abstract: PURPOSE:To obtain a color filter with no bad effect on pickup elements by separately dyeing solid-state image sensing device at a specified color with a direct coating of a layer to be dyed thereon as added to by a chemical material so arranged to take in ion of Na, K or the like. CONSTITUTION:A polyimide-based resin 4 fills irregularities on the photodetecting surface of a image sensing element 1. An Al light-shielding film 5 is provided selectively and a transparent isolation layer 6 is laid thereon through a casein (material to be dyed) 7. Then, a layer 8 to be dyed in which a water solution of metal chelate (dotite or the like) is added to the casein water solution is formed and dried. Then, after a patterning, the layer 8 is immersed into a dyeing liquid to make a red layer 9R. Again, a layer 8 to be dyed is entirely coated and then, a blue layer 9B is made likewise. A transparent isolation layer 10 is provided to prevent mixed colors and subsequently, a green layer 9G is made likewise. This reduces the amount of Na<+> ion in the layer 8 to be dyed to several ppms thereby providing a proper color filter with no bad effect on image sensing elements.

The fine droplets of the light liq. are present in the heavy liq., the diameter of the droplet is increased by collision with a perforated cylinder 18, hence the droplets are separated from the heavy liq., and the heavy liq. is sent to a heavy liq. outlet passage 8. The fine droplets of the heavy liq. colllide with a perforated cylinder 18', the diameter is increased, and the droplets are separated from the light liq. and sent to a light liq. outlet passage 9.

Title: Cooling device for construction machinery
Inventor: WATANABE OSAMU
IPC: F28D1/04
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To allow cooling air to pass without producing any pressure loss and also increase a heat exchanger effectiveness in a cooling device for construction machinery which cools a heat exchanger by a centrifugal cooling fan. SOLUTION: The cooling air path of a radiator 3 and an oil cooler 4 is formed so that cooling air is directed from their peripheral parts to the center of a fan 2 and the cross sectional area of the cooling air is reduced gradually from the upstream to the downstream of the cooling air. Also the fins of the radiator 3 and oil cooler 4 are also formed so that they are inclined from their end part to their center part. By this, the concentration of flow of the cooling air to the core part of a heat exchanger is prevented so as to pass the cooling air efficiently through the entire flow path. Thus a pressure loss can be prevented from occurring and also a heat exchanger effectiveness can be increased.
