IPC: F16F15/04
Filed: 1989-12-08
Abstract: PURPOSE:To avoid resonance of an on-vehicle electronic instrument and the like under the conditions of random vibration by changing a natural frequency through providing a second shock absorber in addition to a first shock absorber. CONSTITUTION:When an on-vehicle electronic instrument 2 and the like vibrates in resonance with applied random vibration, breakage of its parts, deterioration of its performance, etc., are caused. So, it is necessary to prevent resonance. For this purpose, if application of the natural frequency vibration of a first shock absorber 1 has been detected, a second shock absorber 4 mounted separately is operated by means of a connecting means 3 (e.g. an electromagnet). Then, resonance is avoided by changing a resultant natural frequency of the electronic instrument 2. If there are possibilities of other resonances, a third and fourth shock absorber and connecting means are arranged for freely adjusting the resultant natural frequency of the electronic instrument so as to avoid the resonance with applied vibration.

Title: Target detector on moving body
Inventor: KAKINAMI TOSHIAKI
IPC: G08B5/00
Filed: 1987-12-17
Abstract: PURPOSE:To sufficiently detect a target by simple monochromatic image processing by remarking the shape of the target. CONSTITUTION:A part of a binary image is extracted by using a 1st segmenting pattern P1 supporting that a road guide plate is arranged on a remote position and the black picture element ratio of the part is checked. When the ratio is low, a black picture element ratio in a 2nd segmenting pattern P2 supposing a position nearer than the pattern P1 is checked. When the black picture element ratio in the pattern P1 is high, similar processing is applied to an image picked up after a prescribed time and the black picture element ratio in the pattern P2 is checked. When the ratio in the pattern P2 is low in any case, the absence of the road guide plate to be a target is decided, but when the ratio is high, proper smoothing processing is executed and then the configuration feature of the black picture element group is extracted. Since the configuration feature of the target is remarked, sufficient detection of a target can be attained by the simple monochromatic image processing.

Title: Manufacture of member for electric connection
Inventor: IKEGAMI YUICHI
IPC: H01L25/04
Filed: 1989-12-08
Abstract: PURPOSE:To achieve highly effective manufacturing of an electrical contacting member having good property by forming a conductive material by means of fusion spray or evaporation. CONSTITUTION:The surface of a retaining material provided with a plurality of holes 5a, i.e., an insulation layer 2, is covered with a mask 5 which exposes the holes individually. By fusion spray or evaporation, hole in a base 1 is filled with a conductive material through its spraying from over the mask 5, and thus an electro-conducting member 6 is formed, that is followed by removal of the mask. In this manner the electro-conducting member is formed not through plating process, but by fusion spray or evaporation of conductive material, which permits use of a conductive material ensuring inferior plating performance, and also the time of formation can be shortened to a great extent. As a result, electrical connecting members of good property can be manufactured with high effectiveness without particular restrictions on selection of the conductive material used.

Title: Positioning device
Inventor: ISHIMOTO EIJI
IPC: G05D3/00
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To improve positioning resolution and to shorten setting time in a positioning device. SOLUTION: Although grease or rubber-like material are inserted into a gap between the moving part and the fixing part of a positioning device as viscous friction-type damper and mechanical resonance is suppressed in a conventional case, it is removed in the invention and dynamic damper 25 is loaded so as to suppress vibration. Thus, hysteresis caused by a conventional method for using the viscous friction-type damper does not occur. Thus, positioning resolution improves. Then, gel-like materials are used as vibration absorbing materials 29 and 30 used for the dynamic damper 25. Thus, plural resonance point peaks extending to a wide frequency range following the complicated mechanism of a positioning object can considerably be dropped and it is not necessary to drop a feedback gain in feedback control. Consequently, setting time can be shortened.

Title: Device for discriminating sheets of paper
Inventor: TAGAMI GIICHI
IPC: G01V3/08
Filed: 1988-12-21
Abstract: PURPOSE:To accurately detect magnetic information even if skew occurs by measuring the quantity and the direction of the skew of conveyed sheets of paper and giving a timing for starting the read of the magnetic information to a magnetic sensor. CONSTITUTION:The conveyed bank note P shields timing sensors 1a and 1b provided on a line orthogonally crossed with a conveying direction. At such a time, if the bank note P is skewed, a difference occurs between time when it shields the sensor 1a and the sensor 1b. A CPU 17 detects the direction of the skew from the order in which the bank note P shields the sensors and the skewed state is recognized from the direction of the skew and the time difference and stored. Since the timing for starting the read of the magnetic information is given to the magnetic sensors 10a and 10b based on the recognized result, variance based on the skew does not occur in the magnetic information, thereby accurately detecting the magnetic information.
