Title: Method of Hg diffusion into a semiconductor crystal
Inventor: TAKAMI AKIHIRO
IPC: H01L31/0296
Filed: 1992-06-29
Abstract: A method of Hg diffusion into a compound semiconductor crystal 11 including Hg e.g. CdHgTe or ZnHgTe comprises the steps of forming a Hg/Cd amalgam 24 on a region of the semiconductor crystal into which Hg should be diffused, forming a protective film 32 of ZnS on the whole surface of the wafer, and annealing the wafer, whereby Hg vapor generates from the amalgam and diffuses into the semiconductor crystal while the protective film prevents the Hg vapor from diffusing into the atmosphere. Therefore, a complicated temperature profile is not required and the Hg diffusion into the semiconductor crystal is carried out without sealing the wafer in a quartz tube. As a result, instruments and materials are easily handled and an Hg diffusion into a large-sized crystal is possible, in other arrangements. Hg diffusion occurs from a patterned layer of amalgam produced by masking a layer of Cd, exposing it to Hg and then covering it with a protective layer of ZnS. <IMAGE>

Title: Frequency control arrangements
Inventor: VIMPARI MARKUU
IPC: H03C3/09
Filed: 1992-09-21
Abstract: A radio frequency transmission circuit comprises a first signal generator 1 and a second signal generator 2, arrangement 3, 4 for modulating one of the first and second signals to produce a modulated signal, and a mixer 5 to combine the other of the first and second signals and the modulated signal to produce an RF output signal. The first signal is controlled by a feed back loop comprising a second mixer 7 having an input from both the first and second signals. whereby fluctuations in the frequency of the second signal are compensated for by adjustment of the first signal so as to maintain the RF output signal at a substantially constant frequency. The modulation signal may be a QPSK digital signal or an analog signal. The circuit may be used in a digital radio telephone. <IMAGE>

Title: A method of linearizing the transmission function of a modulator
Inventor: DUJPSJOEBACKA ANDERS GUSTAV
IPC: H04B10/2507
Filed: 1992-11-12
Abstract: A method of linearizing a modulator (1) having two parallel-coupled sub-modulators (2, 3). The complete transmission function of the modulator includes parameters which relate to power division (A, 1-A) of a non-modulated carrier wave (Pin) and a relationship (B) between the activation degree of the sub-modulators (2, 3). The transmission function is simplified and series-expanded with two higher-order terms, each having a respective coefficient. An expression for intermodulation distortion is calculated with the aid of the series-expansion and with control signals (V1, V2) having two or three frequencies. The signs of the coefficients are determined so that the terms having these coefficients will mutually counteract their respective distortion contributions, and limited search regions for the parameters (A, B) are calculated with the aid of the sign-determined coefficients. In accordance with secondary conditions for high electrooptic efficiency and pronounced modulation depth, the distortion level of the modulator is calculated with the aid of the complete transmission function in the search regions. <IMAGE>

Title: Bookbinding tape with pre-stressed heat-activatable adhesive.
Inventor: HURRICKS PETER L
IPC: C09J7/35
Filed: 1993-01-25
Abstract: A bookbinding tape 6 is formed where the heat-activated adhesive 16 is prestressed relatively to the tape.

Title: Watch winder
Inventor: NG TAI WO
IPC: G04B37/10
Filed: 1993-10-28
Abstract: The watch winder has a hollow shaft 12 carrying a gear 14 at one end. A knob 13 is fixed to the shaft 12 which has keys 17 which are arranged to pass through keyways in the sides of an aperture 11 in rear surface 10 of the watch. In order to adjust the hands of the watch, the knob 13 is turned until the keys 18 can pass through the keyways. This allows the gear 14 to mesh with a gear 16 connected to the hands of the watch. When the hands are correctly set, the knob 13 is moved upwards to disengage the gears 14 and 16 and then turned to allow the keys 17 to pass through the keyways. <IMAGE>

Title: Multiphase flow monitor
Inventor: JAMES GWILYM DORIEN
IPC: G01N23/222
Filed: 1994-03-01
Abstract: An apparatus and a method are provided for monitoring the contents and flow rate of a multiphase oil pipeline. The apparatus (10) includes a neutron tube (14) as a controllable source of fast neutrons, and two NaI(TI) scintillator units (24, 18), one to detect prompt gamma rays, and one to detect gamma rays from <16>N nuclei generated by activation of oxygen, the latter being several metres downstream. The tube (14) operates in two modes: continuous, to enable the spectrum of prompt gamma rays to be measured; and brief operation, to activate a discrete portion of fluid and so to enable the velocity and oxygen concentration to be determined from signals from the downstream detector (18, 21, 22). The latter signals are used to compensate for the poor resolution of the scintillator (24) used to measure the gamma spectrum during continuous operation, thus allowing the composition of the fluid to be determined accurately. <IMAGE>

Title: Self-propelled cleaning device for pipes
Inventor: KATAYAMA SHINZO
IPC: B08B9/053
Filed: 1994-03-30
Abstract: A cleaning device is disclosed which, by selection of the nozzles to be used, can either be propelled along the inside of a pipe by jets of cleaning fluid or, as well as this, to move around the inner wall of the pipe while part of the device provides a rotating pattern of jets. The choice is made by adjusting the position of valve 26. If it is forced against seat 27, fluid supplied by hose 7 can only escape through holes 13 as propelling jets "a". If screw 23 is slackened, fluid can move valve 26 to the Fig. 5 position, where fluid is also supplied to oblique passages 19 so that rotor 15 gives a revolving pattern of jets "b". Further, passage 16 yields single jet "c" which drives the device against and around the inner pipe wall (Fig. 4, not shown). Tongue 20 may be replaced by a set of roller bearings around the periphery of rotor 15. <IMAGE>

Title: Colour correction
Inventor: EELES ALAN GEOFFREY
IPC: G03C7/333
Filed: 1994-04-11
Abstract: Colours obtained in photographs are never a perfect reproduction of the colours in an original scene as a result of unwanted colour absorption in one or more of the dye layers which affects the overall performance of the imaging system. A method of correcting for unwanted colour absorption in at least one developed image dye layer of a colour negative film, e.g. green adsorption in cyan layer 38 comprises re-exposing the developed film with light having spectral characteristics similar to that of the unwanted colour absorption e.g. green such that the layer sensitive to this light e.g. magenta layer 36 is masked by the silver image 38b formed in the cyan layer 38 to form magenta images 36a' and silver images 36b' and further developing to form a masked image of the scene. <IMAGE>

IPC: G01R31/04
Filed: 1995-10-07
Abstract: An 'S' type plug that is usually used to connect 12 volt accessories on a caravan onto the towing vehicles 'S' type socket. The 12 'S' type wiring allocation tester is inserted into the 12 'S' type socket on the towing vehicle and the sequence of the light emitting diodes is noted in order to show the correct operation or malfunction of the wiring upto the 12 'S' socket.
