Title: Method for detecting distance by video
Inventor: HIRABAYASHI TAKEHIDE
IPC: G08G1/16
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To accurately detect a distance by confirming the reliability of detection result by a video of an object which is received by an image sensor means. SOLUTION: A video is given to a pair of image sensors 21 and 22 within an image sensor means 20 from an optical means 10, so that a pair of video data D1 and D2 showing its pattern are generated, and partly groups d1 and d2 which are respectively extracted by shifting the position successively from window part data WD1 and WD2 that are extracted corresponding to a visual field S from both video data to a corelative value calculation means 30, are combined to make Ck and a corelative value Vk between the partly groups is calculated per combination.  Then, gradients ϕ<-> and ϕ+ on the positive and nagative sides are obtained as maximum corelative sharpness for evaluating the detection reliability according to the changes of corelative value adjacent to a shift value s that shows the maximum corelation through a reliability testing means 50, and only when they are higher than the specified level, it is judged that an object 1 exists within a visual field S, and its distance is detected.

Title: Copying device
Inventor: YAMAMOTO YOSHIHARU
IPC: G03B27/73
Filed: 1982-11-24
Abstract: PURPOSE:To sharply copy characters, drawings, etc., on an original having a colored background by changing light spectra exposing a photoreceptor through a color filter. CONSTITUTION:For example, a color filter 21 is inserted between an illumination section 14 and an original section 11, the characters, drawings, etc. of the original 13 illuminated through the filter 21 are projected on a photosensitive body 16 by an image-forming optical system 15 to form an electrostatic latent image. When a color filter 21 set high in transmittance of long wavelength region corresponding to the red light is inserted between the illumination section 14 and the original section 11, poor exposure of a photosensitive body 16 due to deficiency of the spectral component in the short wavelength region of the colored background part can be complemented with the long wavelength spectral component, and on the other hand, even if there is a part high in reflectance in a part of the original, such as lack of attached toner, it is prevented only by increasing a spectral component in a part of the long wavelength region. As a result, an electrostatic latent image good in contrast can be formed on the photosensitive body 16.

Abstract: PURPOSE:To heighten speed of rising of a hammer ram, increase efficiency of work and lengthen life of forging die etc. by providing a mechanism that increases the quantity of working fluid that flows in and out to and from a driving cylinder at a stroke when the hammer ram of a forging machine goes up. CONSTITUTION:Working fluid is introduced to an inlet/outlet port 36 of a multiple stage cylinder machine 25 and discharged from an inlet/outlet port 35 by a control device, and at the same time, working fluid is introduced to an inlet/ outlet port 52 of a cylinder mechanism 47. Consequently, an inner valve body 39 is pushed up momentarily resisting pushing up force of a spring 45 through a piston 48 and a sleeve 44. Accordingly, area of communication between the first valve hole 21 and a groove 42, and area of communication between the second valve hole 22 and flow out passage 15 of working fluid are enlarged. Consequently, the quantity of working fluid that flows into the lower face side of the piston of driving cylinder of the hammer ram increases momentarily, and therefore, the piston and the hammer ram supported by this go up at high speed.

Filed: 1985-09-19
Abstract: PURPOSE:To prevent an accident such that fingers etc. are pinched by a window glass by stopping the movement of the window glass by the detection output of a proximity switch when a limit switch responding to the rise of the window glass, is not in operation, during the rising operation of the window glass. CONSTITUTION:The output of a proximity switch 5 is connected to the driving coil of a relay 7 through a limit switch 6. Therefore, if fingers, etc. are on the upper part of a window glass 14, a sensor 5a performs detection operation, and the relay 7 is operated through the limit switch 6 normally in closed state. If a seesaw switch 1 instructs the rise of the window glass 14 at this time, in other words, the seesaw switch 1 is on the U-side, and the contact point of the relay 7 is in the wiring for stopping the movement of the window glass 14, the contact point 7a of the relay 7 is opened to stop a driving motor 2, and also the window glass 14 stops. Therefore, the movement of the window glass 14 is automatically stopped according to the approach of the fingers, etc., and the accident such that fingers, etc. are pinched by the window glass 14 is prevented.

IPC: F24F7/013
Filed: 1987-08-21
Abstract: PURPOSE:To save the time of filter cleaning by a method wherein at the front part of a main body a plurality of filters composed of respective plates with a number of holes formed in them are installed in the condition that they can be exfoliated and are piled up in layers. CONSTITUTION:For instance, two sheets of filters 17 are formed by vacuum molding of plastics and a number of holes 17b are formed in their thin plate parts 17a. When ventilating operation is carried out, oil content and dust stick solely to the filter 17 in the front layer. This filter 17 in the front layer is exfoliated and the filter in the next layer and unused condition is exposed as the front layer and consequently filter cleaning can be obviated. As each filter 17 is composed of a perforated plate, it is easily cleaned and the filter once used can be therefore used again. Though the filter in the next layer is a so-called spare, it is placed in a main body 11 and it is not necessary to store it in another place.

Title: Abrasion testing machine of trolley line
Inventor: OURA YASUSHI
IPC: G01M99/00
Filed: 1987-08-21
Abstract: PURPOSE:To enable testing of the abrasion of a trolley line under the same conditions as in the actual running, by adding sufficient tensile force to the trolley line, with no connections or joints, for avoiding waving of the trolley line. CONSTITUTION:A trolley line 3 is wound one time around the outer periphery of a rotary disk 2 mounted in a driving shaft 9. The opposite ends of the trolley line 3 are slipped in an axial direction to be drawn outside and fixed to the rotary disk 2 by means of a fixing device 17. Therefore, the trolley line 3 can be given sufficient tensile force, resulting in no waving thereof along the outer periphery of the rotary disk 2. As a result, the trolley line 3 is stretched to be a true circle. Moreover, because of the tensile force, the trolley line 3 can endure its own centrifugal force, and accordingly it can rotate at high speeds. Further, since the trolley line 3 has no joints or is not jointed, the abrasion of the trolley line can be tested under the same conditions as in the actual running.
