Patent EP-0646781-A2 (EP)
Inventor: KIMMIG LUDWIG
IPC: G01M3/32
Filed: 1994-09-15
Abstract: For testing the tightness of the gas withdrawal system of a gas analysis device, the gas withdrawal system is sealed, the measuring gas pump is switched on for a period which is safely sufficient to achieve the maximum underpressure. During this time, a flow meter measures the flow. The pump is then switched off and is switched on again after a predetermined time. In the event of a leak, the gas which has penetrated into the withdrawal system is conveyed so that the flow meter determines a flow. By means of comparing the amplitudes of the two flow meter signals it can be established whether and to what magnitude a leak is present. The invention is applied in vehicle exhaust gas measuring devices. <IMAGE>

Abstract: A mobile communication apparatus is provided, in which the linearity during a small output power of a radio-frequency power amplifier can be maintained as during a large output power. The input signal power to a radio-frequency power amplifier (11) is decreased by an attenuator (32) during a small power output. The resulting downward trend of the transmission signal power is compensated for by increasing the gain of the radio-frequency amplifier circuit (11) through a transmission power control circuit (14). Under this condition, the radio-frequency power amplifier (11) is made operable in a linear region of the transistor in the same manner as during a large power output. As a result, the linearity of the amplifier is guaranteed over the whole operating range of the transmission power.

Abstract: The invention relates to an electron tube, in particular X-ray tube with a cathode arrangement which comprises an electron emitter which is connected to supporting pins which, in turn, are connected to the cathode structure in each case via one fastening element. In this case, particularly simple adjustment of the position of the heating filament results from the fact that the fastening elements in a first region are connected to cathode structures in a second region, which is at a distance from the first region, to the asssociated supporting pin and that the fastening elements have between the first and the second region a deformation region by means of the deformation of which the position of the electron emitter can be adjusted relative to the cathode structure. <IMAGE>

Abstract: In a high efficiency encoding method in which pre-set bit allocation is made for digital information signals of plural channels and in which coded information signals are produced by the allocated bits, it is desirable to avoid sound quality deterioration produced by pre-echo during abrupt changes in the information signals as well as to suppress pre-echo to ensure aurally desirable bit allocation. To this end, in a high efficiency encoding method in which digital information signals (31, 41) of plural channels are normalized by normalizing units (37, 47) and pre-set bit allocation is made by a bit allocation unit (38) to effect pre-set bit allocation, the amounts of bit allocation between channels are controlled on the basis of temporal changes of the information signals of the respective channels. Also, the amounts of bit allocation between channels are controlled based on temporal changes of the amplitude information of digital information signals of the respective channels. At least a part of the bits that may be used for bit allocation is preferentially allocated for channels having larger temporal changes of the information signals depending on the magnitude of temporal changes of the information signals among the plural channels. As a result, deterioration in the sound quality due to pre-echo during high efficiency encoding may be prevented in a system having plural audio signal channels.

Abstract: A pilot signal is superposed and recorded on data at the beginning of each track. The beginning part of the track is constituted by using only codewords of which disparity in every 10 bits is +2, 0 or -2. The beginning part of track is also constituted so that the cumulative value of the disparities of every 10 bits may increase or decrease in the period of the pilot signal to be superposed. Therefore, the frequency spectrum in the beginning part of the track has a peak at the frequency of pilot signal, and using this peak as pilot signal, tracking is controlled in reproduction.

Abstract: A tag server system provides unique tag values to many client systems. The tag server system comprises a processor that generates an inventory of unique tag values, such values being generated by monotonically increasing a value within the tag body field. A memory is provided for storing the inventory of unique tag values. A nonvolatile memory is controlled by the processor and stores a highest unique tag value generated by the processor. The processor implements a tag value recovery procedure and is responsive to a data loss failure mode in the tag server system to cause a readout of the highest unique tag value from the non-volatile memory. The processor is responsive to that highest unique tag value to commence generation of new unique tag values monotonically from that value and expends no effort to regenerate lost unique tag values that are less than the highest unique tag value derived from the non-volatile memory.

Abstract: An antireflectance coating is disclosed comprising a first graded layer wherein the composition is varied throughout the thickness of the layer such that the refractive index of the graded layer varies from a low refractive index approximately matching the refractive index of the substrate at the interface of the graded layer and the substrate to a higher refractive index at the surface of the graded layer opposite the interface with the substrate, and a second substantially homogeneous layer of a composition selected to have a refractive index which is approximately the square root of the product of the higher refractive index of the graded layer and the refractive index of the incident medium at the surface of the second layer opposite the interface of the second layer with the graded layer, having an optical thickness of approximately at least one quarter of a selected design wavelength. The antireflectance properties of the coating of the present invention can be expanded to a broader range of reflected wavelengths by incorporating, between the graded layer and the second substantially homogeneous layer, an intermediate layer having a relatively high refractive index and an optical thickness of about half the design wavelength.
