Abstract: A microprocessor (10) or other integrated circuit including a clock generator circuit which is dependent on an externally-provided reference signal (XTALCLK) includes the capability of detecting the loss of this externally-provided reference signal and producing an alternate clock signal despite the loss of the reference. In a particular embodiment, the clock generator comprises a phase locked loop frequency synthesizer (23-27) which normally relies on an external crystal oscillator for its reference frequency signal. The generator includes a circuit (22) for detecting abnormalities in the crystal signal and switching the voltage controlled oscillator of the frequency synthesizer to an internally-generated reference voltage. In the particular embodiment, the clock generator is also capable of producing a reset signal in response to the loss of the reference signal.

Abstract: The present invention relates to a method and apparatus for mono-crystalline growth of a dissociative compound semiconductor. The method, which is based on the Czochralski method, includes the following steps. First, a first volatile component material and second material of the dissociative compound semiconductor are prepared. The first material is placed on the bottom of an inner air-­tight vessel which is contained in the outer air-tight vessel. The second material is contained in a crucible in the inner vessel. The crucible is supported by a lower shaft extending from the inside to the outside of the inner vessel. The first material is, next, heated for evaporating so as to react with the second material in the crucible. Therefore, the dissociative compound semiconductor is synthesized in the crucible. Then, a single crystal is pulled up from the melt by an upper shaft. The upper shaft extends from inside to outside of the inner vessel, thereby the single crystal is grown. The improvement is that the pulling-up process includes the steps of, after the heating step: measuring the weight of the melt in the crucible, the weight of the melt being influenced by a difference between the interior pressure of the inner vessel and a pressure outside of the inner vessel; correcting the measured weight of the melt for the error due to the pressure difference, thereby obtaining an accurate data of the weight of the melt; and controlling at least one of a composition and a diameter of the growing crystal on the basis of the weight data of the melt.

Abstract: An optical transmission spectrometer for transmission measurements of absorbing and scattering samples includes light sources mounted parallel to each other in a holder. The beams of light eminating from the light sources are directed through a beam-combiner. The beam-combiner includes a first refractive surface at an angle of incidence of 45°. The first refractive surface refracts light toward a common axis. The beam-combiner includes a second refractive surface parallel to the first refractive surface for refracting the beam of light along a common axis parallel to the original direction of the beam of light. The beam-combiner can include additional refractive surfaces for other beams of light to combine the beams of light into a primary beam. The includes a collimating tube extending along the common axis for baffling stray light and directing the primary beam through a sample. A second collimating tube is provided on the side of the sample opposite the first collimating tube for baffling stray light passing through the sample. The second collimating tube directs the primary beam to a detector package mounted in a holder, where the detector viewing area of the sample is limited to that of the primary beam.

Abstract: A tamper-proof and tamper-evident fitting for a beverage container has an annular member (7) which is located over the projecting lip portion (3) of the outlet housing (1) and thereafter clenched by deforming the lower part of the outer peripheral rim (7b) around the top lip (3) of the housing. The inner peripheral portions of the annular member comprise leaf like parts (8) which are directed inwardly and downwardly. 
     When an attempt is made to remove the closure member (4) from the outlet housing (1), the leaf parts (8) snag on the threading (5) and with the applied rotational force deform upwardly. At some stage during this removal process a tang or other stop member (9) will prevent further removal. Due to the leaf portions (8) snagging the threading (5) any attempt to screw the closure member back into the outlet housing will result in severe deformation of the parts (8) and complete jamming of the assembly occurs.

Abstract: For a future information transmission network with a synchronous hierarchy of the digital signals, CCITT Recommendation G.709 prescribes that digital signals of the plesiochronous hierarchy are to be inserted into multiplex elements with prescribed pulse frames. In this arrangement the pulse frame is structured word by word but at the end of certain words, more or fewer bits must be stuffed bit by bit. The invention specifies a multiplexer for forming such a pulse frame and a demultiplexer for demultiplexing such a pulse frame and eliminating the stuffing bits, the multiplexer operating word by word and repeating such bits (14, 15) of a stuffing word (Z) as starting bits of the next word (Wi-1) following. Similarly, the demultiplexer also operates word by word and eliminates the stuffing bits contained in a word by overwriting them when the next word following is written into an elastic memory. In both cases, this is done by controllable displacement of memory addresses.

Abstract: A bias voltage U B  including a sine-wave voltage U T sinω ot and an off-set voltage U REG  is applied to an electrode (14) on a sample (10). A potential U₁ of the electrode (14) is represented by: U₁ = U REG  + U T sinω  o t. A voltage including the bias voltage U B  and a voltage ΔU is applied to an electrode (16) on the sample (10). A probe (12) is approached to the sample (10) by several nm, and a tunnel current I T  flows therebetween. And the probe (12) scans the surface of the sample. During the scan, the position of the probe (12) is servo-controlled in the z-direction, to make constant the average abso­lute value of the tunnel current. The servo voltage is recorded thereby obtaining an STM image. Given that the potential difference between the electrode (14) and a surface portion facing the probe (12) is U S (x), the average of U₁ + U S (x) becomes zero when the average of the tunnel current I T  is zero. Accordingly, <U S (x) + U REG  + T T sinω  o t> = 0, that is, U S (x) = - U REG . Thus, by recording - U REG  the potential distribution U S (x) on the sample surface is determined. Spectroscopic data is obtained by an analog operation unit (32), on the basis of a differential conductance ∂I T /∂U T  calculated from the tunnel current signal I T  and the bias voltage U T .
