Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To make easily drivable an illumination system, to reduce heat generation, and to make it possible to pick up a clear, good-visibility image by using an LED as the generation source of a flash. SOLUTION: An illumination module 510 is fitted to a vehicle body, and it is constituted of an LED holder 511 extended in the longitudinal direction of a rail 20 and an LED 512 serving as a luminous source. Every time an inspecting/measuring vehicle passes through a rail gap 22, a camera 31 is triggered by a trigger section 430 in response to the detection signal of a laser reception section 42, and the LED 512 is pulse-driven. A flash light is emitted from the LED 512 toward a rail top face and the rail gap 22 to brightly illuminate there. The rail top face is photographed by the camera 31 when it is illuminated. Most of disturbance light is removed by a filter 520, and a clear image is obtained based on the illumination light from the LED 512 and thereby the rail gaps 22 are selected and intermittently photographed via small electric power at ordinary temperature.

Title: Finned heat exchanger
Inventor: KOMATSUBARA KOSUKE
IPC: F25B39/02
Filed: 1984-12-27
Abstract: PURPOSE:To prevent the growth of frost at the leading edge of the fin and prevent the reduction of heat exchanging amount by a method wherein multiple bent tongues constituted by cutting a fin plate and separating it from the fin plate, are arranged continuously in the orthogonal direction of airflow. CONSTITUTION:The bent tongue piece 7 is arranged so that the three sides thereof are cut and separated from the plate fin 1 at the side near heat transfer tubes under remaining one side thereof, therefore, heat is transferred from the heat transfer tube to the leading edge of the fin under detouring the bent tongue piece 7 as shown by arrow signs in the diagram. As a result, a temperature difference between the leading edge of the fin and heat exchanging air is contracted and the growth of frost at the leading edge of the fin is restricted. Further, the growth of frost, adhered to the lading edge of the fin, is precluded and clogging between the plate fins due to frosting 4 is prevented whereby the surface of the fin is frosted uniformly. Accordingly, the operating time of the heat pump may be elongated remarkably. Airflow, passing through openings 8, is generated between neighboring fins and the mixing of airflow is promoted, therefore, the heat transfer coefficient of the surface of the fin may be improved and the performance of the heat exchanger may be improved.

Title: Image processor
Inventor: YOSHIDA TOMOYUKI
IPC: H04N1/409
Filed: 1993-11-10
Abstract: PURPOSE:To prevent white in a thin character from being blurred or the gradation of a false half tone image from being deteriorated by extracting the density of an input image between two set thresholds, and in the case of changing the density, applying sharpening processing to the density data of the input image and outputting the sharpened density data to a density converting means. CONSTITUTION:The density data of 8 bits e.g. are inputted to a sharpening processing part 2 or a smoothing processing part 3 through a change-over switch 1 and sharpened or smoothed. The sharpened or smoothed density data are inputted to a density conversion part 5 through a change-over switch and the desity is converted based upon thresholds TH1, TH2. Even when an output character can not be read out because its original character is a small and thin character whose inside white part is blurred, white density data are reduced by applying the sharpening processing and the density data of character strokes are increased. On the other hand, smoothing processing is applied to a false half tone image in which comparatively large density changes are continued.

Title: Magnetic recorder-reproducer
Inventor: INOUE SHOICHI
IPC: G11B5/60
Filed: 1990-10-22
Abstract: PURPOSE:To make it possible to use both front and rear surface of a recording medium and to improve a track density by providing a pair of recording- reproducing heads at an odd-number position and an even-number position in respect to tracks on the opposite sides of the recording medium and by providing a prescribed tilt angle for a gap of the recording-reproducing head on one side. CONSTITUTION:Tracks 1, 3 and 5 at odd-number positions are data tracks recorded by one recording-reproducing head 26 and have a tilt angle theta1, while tracks 2 and 4 at even-number positions are data tracks recorded by the other recordingreproducing head 27 and have a tilt angle theta2. Since both of the recording-reproducing heads 26 and 27 have tilt angles in the same direction to the direction of rotation of a disk 25, the relative tilt angles of the adjacent data tracks recorded by the paired recording-reproducing heads 26 and 27 being present oppositely to each other are reversed to each other and become theta1+theta2, thus making an azimuth loss effect large. Therefore mutual interference decreases. According to this constitution, the widths of guard bands 6 to 9 can be made narrower and a track density can be improved.

IPC: H03H9/25
Filed: 1989-10-30
Abstract: PURPOSE:To improve the resonance characteristic by providing an electrode finger gap on respective plural electrode fingers, decreasing the cross length of adjacent electrode fingers as being apart from the center of the interdigital driving electrodes and selecting the shape of an area surrounded by line segments tying both ends of each electrode finger cross part to be asymmetrical. CONSTITUTION:The electrode finger gap 22 is provided on the interdigital driving electrode 2 so as to decrease the cross length of adjacent electrode fingers 21 as being apart from the center of the interdigital driving electrode 2. Moreover, the shape of an area surrounded by line segments tying both ends of the crossing part of each electrode finger 21 is selected to be asymmetrical to a straight line passing through the center of the interdigital driving electrode 2 in parallel with the propagation direction of the surface wave, that is, the X-X line. Thus, the length (SIGMAa) of the crossing of the electrode finger 21, that is, the accumulated length of the part exciting a surface acoustic wave in the propagation direction is averaged over the entire electrode width of the interdigital driving electrode 2 and the surface acoustic wave energy distribution in the lateral direction is almost uniformized. Thus, the degradation in the resonance characteristic hardly takes place even with too strong excitation.
