Title: X-ray inspecting apparatus and film used therefor
Inventor: YAKOBU UINANDO MURUDAA
IPC: G21K3/00
Filed: 1991-04-15
Abstract: PURPOSE: To reduce a spatial brightness change in an X-ray image which occurs due to vignetting by loading a liquid reservoir in an X-ray absorption filter. CONSTITUTION: An X-ray beam 3 incident on the input screen 5 of an X-ray image reinforcing tube 7 emits light in an light-emitting layer behind the glass envelope of the screen 5. A lightemitting image on an output screen 9 which displays it is displayed by a television image pickup 13 through a twin optical device 11. The image pickup 13 generates an image signal proportional to light intensity detected by the input screen and applies it to a television monitor 15 and a controller 25. Furthermore, an adjustable filter 21 which the controller 25 can adjust through a liquid pump 23 on the basis of an image signal, is arranged between the X-ray source 1 and the reinforcing tube 7. And then liquid is supplied to or taken out from the filter 21 by the pump 23 until the image signal at the edge of an X-ray image equals that at the center thereof by the uniform radiation of the screen 5.

Abstract: PURPOSE:To aim at reducing resonating sound, voltex sound, etc. in the casing of a centrifugal blower, by forming the casing with the use of a composite vibration damping steel plate structure or the like, which is formed by clamping a viscoelastic polymer material such as, for example, rubber having a sound absorbing characteristic, between steel plates. CONSTITUTION:A viscoelastic polymer material 6 such as, for example, rubber, having a sound absorbing characteristic is applied on one surface of a seel plate 5, and further, another polymer material is clamped between steel plates 5 from both sides thereof. Thus, composite vibration damping steel plate structures 3, 4 are prepared. Further, the steel plate structure 3 is formed in a sprial shape with the viscoelastic polymer material 6 facing outward to form a spiral plate 9. Or the steel plate structure 4 is formed into a spiral shape to form the sriral plate 9. Further, a side plate 7 formed of the steel plate structure 3 or 4 is used to form a suction port 8. Further, with the use of the sprial plate 9 and the side plate 7 a blow-out port 10 is formed. Since the blower casing is formed of a vibration damping steel plate structure, resonating sound and voltex sound in the casing may be reduced.

Abstract: PROBLEM TO BE SOLVED: To improve the scraping efficiency of cuttings including a cutting oil by arranging plural recessed parts on the outer peripheral part of a non-magnetic cylindrical element within the contact length of a scraper, in a device which is equipped with the non-magnetic cylindrical element having a magnet unit arranged slantly and scrapes magnetically attracted magnetic material cuttings with the scraper to complete the conveyance of the magnetic material cuttings. SOLUTION: The magnet pipe conveyor which moves upward from a receiver for cuttings to a deoiling device contains a magnet unit 6 made up of permanent magnets 7 arranged helically in a freely rotating manner in a non-magnetic cylindrical element 5. The cuttings of a magnetic material are magnetically attracted with the permanent magnet 7 by rotating the magnet unit 6 and are scraped with a scraper 10 on the upper end part of the magnet unit 6 by moving the magnet unit 6 over the surface of the non-magnetic cylindrical element 5.

Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To improve the differential gain of a color signal that is caused by the difference of bias frequency by keeping a constant reproduction level of the low band converted color signal which is biased to an FM luminance signal regardless of the level of a luminance signal. SOLUTION: A 1st equalizer 5 inputs an FM luminance signal Y and then outputs this signal with its gain increasing as its frequency becomes higher. A mixer 9 mixes together a color signal C that is converted into the frequency lower than the FM luminance signal received from a C terminal 1 and the signal that is outputted from the equalizer 5. Then a head amplifier 10 sets the recording current of the FM luminance signal so as to make the output characteristic of a low band converted color signal change sharply in response to the luminance signal level when the output signal of the mixer 10 is magnetically recorded.

IPC: H04B7/10
Filed: 1984-04-23
Abstract: PURPOSE:To detect automatically a reception circuit caused by deterioration of sensitivity by obtaining an integration means value of a level difference of each reception circuit in an angular diversity reception system having plural reception circuits. CONSTITUTION:Outputs of plural directivity antennas 10a-10f are connected cyclically to three reception circuits 40A-40C via a switching circuit 30. Outputs of the reception circuits 40A-40C are selected by a gate circuit 60 and outputted to the post-stage. A control circuit 50 controls the switching circuit 30 so that the reception level is a prescribed level or over. Moreover, the control circuit 50 decides the order of the reception level of each reception circuit, obtains a level difference of each reception level every time the order is changed and integrates the result at each reception circuit. Then the mean value is obtained by dividing the integration value with the number of times of the order change and a reception circuit caused for the deterioration of sensitivity is decided by the mean value.

Title: Optical waveguide device for surface illumination
Inventor: FURUKAWA MASAAKI
IPC: G02B6/00
Filed: 1992-03-04
Abstract: PURPOSE:To uniformalize the brightness of the surfaces of a liquid crystal display panel, etc., with the optical waveguide device for illuminating these surfaces, to provide high brightness on this device and to miniaturize the device. CONSTITUTION:Plural planar optical waveguide layers 5a, 5b, 5c... successively having refractive indices N1>N2>...>NK>>NL are laminated on a low-refractive index layer (NL) or highrefractive index layer 4 arranged to inverted V configuration. The light of the light source 2 within a cavity 8 for the light source is made incident from the respective light incident end faces 7a thereof and the light diffusion layer 3 of the refractive index NK>NL is brightened by the light emitted from the light emission end face 7b of the flat surface. Although the light propagating in the underlaid long planar optical waveguide layer 5a weakens, the light of the adjacent planar optical waveguide layer 5b is propagated by total reflection between the planar optical waveguide layer 5c laminated thereon and the low-refractive index layer or the high refractive index layer 4. This light is made incident on the planar optical waveguide layer 5a and interferes therewith to compensate the deficiency of the light quantity thereof. The brightness of the surface is thus uniformalized. Since there are no layers to cause a light loss in the optical paths, the high-brightness illumination is assured and since the light source 2 is internally provided at the center, the device is miniaturized.
