Patent EP-0458601-A1 (EP)
Inventor: ICHIMURA TSUTOMU DAI GREEN HAI
IPC: G01N21/47
Filed: 1991-05-21
Abstract: For measuring spectral absorption characteristics of an opaque specimen, apparatus of Fig. 4 comprises a variable wavelength laser which can continuously emit monochromatic light over a wide spectral range, a beam converter 11 positioned to convert light from the laser into parallel rays, a beam splitter BS positioned to produce from the beam (i) rectilinear light which strikes a specimen 20 which transmits light, e.g. a dilute suspension or translucent biological specimen, which scatters the light, the forward component of which is combined with the incident light by a half-mirror HM, and (ii) reflected light which passes through a shifter AO where its frequency is slightly changed before being recombined with the forward scattered light in a detector 2 which can be a highly directional detecting system or a heterodyne system, which are further described (Figs. 1 to 3). 
     For measurement of absorption of a specimen within a scattering medium, the final light path is modified by altering the position of the half-mirror (HM) and of the specimen 21, which is placed behind a sample of the medium NZ, so that the light passing through the medium is reflected by the specimen and again through the medium and then combines with the forward scattered light at the half-mirror and passed to the detector. 
     Several other arrangements of the components of the apparatus are shown, for measuring various types of specimen which absorb or scatter light, including some which use a Michelson light-receiving system for a reflecting specimen, or a highly directional optical system. 
     For measuring spectral absorption characteristics of a reflecting specimen when the intensity of the reflection component of incident light is high, the regular reflection component is removed in apparatus (Figs. 10 and 11) by means of a beam trap BT which receives light from the specimen 21 via an angled mirror M5. 
     Other apparatus can measure either transmission or reflection spectral absorption characteristics in a microsized region (Figs. 12 and 13) and including Cassegrain reflection optical systems disposed confocally and having a pin-hole P at the confocal point, from which the scattered light extracted passes to a detector 2. 
     Modifications of the apparatus allow a microscopic absorption distribution in an opaque specimen to be measured, by changing the relation between the specimen and the beam of directional parallel light, so as to apply incident light to a very small point region corresponding to a 0-order difraction component (Figs. 15A to 17). 
     The spectral absorption characteristics of a specimen are thus measured with high accuracy and simply and without picking up extraneous scattered light, and the invention is especially useful for examination of specimens of animal tissue.

Abstract: In order to produce, by spinning, a workpiece of a material which is non-malleable at room temperature, a heated mandrel (24) is used which is equipped on the inside with an electrical resistance element (46) surrounded by a diffuser (48). The heating temperature of the mandrel (24) is adjusted by a regulator (66) placed in a unit (26) which rotates with the mandrel. Advantageously, this temperature is equal to the forming temperature of the material in question, reduced by the temperature rise of this material due to the effect of the spinning. <IMAGE>

Abstract: A cathode ray tube apparatus comprising a cathode ray tube (10), a deflecting device (13), an inverse voltage supply section (14), and a pair of compensating radiators (15). The deflecting device (13), which is mounted outside a funnel (11) of the cathode ray tube (10), deflects electron beam for scanning, emitted from an electron gun in a neck (12) of the funnel (11). The inverse voltage supply section (14) is used to obtain a voltage opposite in polarity to a deflection voltage applied to deflecting coils of the deflecting device (13). The compensating radiators (15), which are arranged individually on the top and bottom of a panel wall, receive the voltage of the opposite polarity from the supply section (14). The compensating radiators (15) are designed so as to generate electric fields which are opposite in polarity to a leakage electric field. Thus, AC electric fields leaked from the cathode ray tube apparatus and a cathode ray tube image display apparatus are suppressed by the compensatory electric fields.

Abstract: The drive hub for a vehicle, in particular for a bicycle, comprises a hub axle 1, a hub sheath 9 which can be rotated relative thereto and a driver 13 which is mounted on the hub axle 1. The driver 13 drives the hub sheath 9 via a ball-and-socket friction gear 17 whose ball carrier discs 25 and 27 form, with the hub axle 1, a rigid gear box whose balls 35 are involved in frictional engagement with a guide ring 33, a drive ring 51 and a drive ring 55, which engagement permits different speeds of revolution by swivelling the axle pins 37 between drive ring 51 and drive ring 55. The contact forces are produced by a thread 47 between driver 13 and drive sheath 49 in proportion to the drive torque, the compression spring 57 guaranteeing a response of the ball-socket friction gear 17 which is free of dead-centre points. The continuously variable transmission ratio of the ball-socket friction gear 17 is controlled through a fixed cone 29 via a control device 79 consisting of rotational elements which cause a link wheel 91 to rotate, as a result of which the helical guide grooves 95 move the ball projections 39 of the ball axles 37 radially outwards or inwards depending on the direction of rotation. The ball axles which are swivelled in this way ensure a continuously variable transmission ratio between drive ring and output ring. <IMAGE>
