Abstract: In hearing aids to be worn in the ear, the problem of contamination of the sound outlet opening by cerumen occurs. The cerumen protection plates hitherto known do not meet all requirements to be set for them. 
<??>A cerumen protection device is proposed which consists of a bow (7) connected to the auditory canal part (3) of the hearing aid but which allows any cerumen deposited to be easily removed without there being any possibility of damage to the sensitive electrical components located within the hearing aid.

Abstract: In a hot isostatic pressing (HIP) method, only the probe of a dilatometer (8a,8b) is set in the pressurized heating space of the HIP apparatus, and the probe is attached with a test-piece (10) having a greater specific surface area made of the same material as the body to be treated (14). The test piece (10) is treated by HIP together with the body to be treated, and the beginning of the contraction of the test piece is detected by the dilatometer (8a,8b). Then, the body is densified by keeping the pressure and the temperature not lower than those at the beginning of contraction of the test piece. According to the method of the invention, since suitable HIP treating conditions are determined immediately, each body to be treated can be treated by only one HIP suitably without repeating the troublesome HIP process. Besides, since the body can be treated by HIP without elevating the temperature beyond the necessary temperature, the crystal grain growth of the body to be treated can be inhibited.

Abstract: An adaptive digital filter for estimating a response characteristic of a signal path by monitoring a sampled output signal of the signal path, estimating a predetermined number of filter coefficients which represent the response characteristic of the signal path, and generating an estimated output signal of the signal path using a plurality of successive sampled input signals of the signal path and the estimated filter coefficients, where the estimation is carried out so that a difference between the output signal and the estimated output signal is reduced. Each of the filter coefficients is extracted by a low-pass filter where the low-pass filter coefficient in the low-pass filter can be set to a constant. Normalization can be carried out in either the input side or the output side of the low-pass filter. Otherwise, the low-pass filter coefficient may be set to 1-K·X j (m) 2 /r, where r is set equal to a norm of the sampled input signals in the beginning, and is then set to an integrated power of the sampled input signals.

Abstract: A vertically arranged plurality of trays (12) are each formed with a cut-out (12E) at a rear corner. The trays (12) are arranged so that the corner where the cut-out (12E) is formed is lower than the other corners. Vertically upward extending rear and side walls (12D, 12B) are provided on each tray (12) adjacent the cut-out (12E). A downwardly extending side wall (12C) is formed on the tray (12) opposite the upwardly extending one (12B). The trays (12) can be selectively shifted by cylindrical cams (44) to positions wherein sheets of printed matter can be ejected thereonto. Due to the skewed angle of the trays (12) the sheets slide to the corners where the cut-out (12E) are formed. After sheet collation a tray drawing device pulls a tray (12) rearwardly to a stapler which fastens the sheets at the corners which extend into the cut-out (12E). The tray drawing device then returns the tray (12), the trays (12) are shifted vertically by the cylindrical cams (44), and the next tray (12) is pulled to the stapler.

Abstract: A novel catalyst system, a process for using the novel catalyst system, and a product made from the process is described. The novel catalyst system is specific for producing polyethylene terephthalate made from reacting terephthalic acid and ethylene glycol, wherein the catalyst system includes antimony; cobalt and/or zinc, and at least one of zinc, magnesium, manganese or calcium. The antimony is generally present from about 150 ppm to about 1100 ppm. The cobalt and/or zinc is usually present from about 5 ppm to about 60 ppm, and the zinc, magnesium, manganese or calcium, as the third component, is generally present from about 10 ppm to about 150 ppm. The amounts of all catalyst components are based on the theoretical yield of the polymer. Using the novel catalyst system to produce PET drastically increases the polymerization rate. In the process, the novel catalyst system can be introduced any time before the polycondensation stage of the manufacturing process.

Abstract: The system produces an acoustic vibration canceling noise creative vibration induced in synchronism with an engine revolution. The system generates a rectangular wave signal having a 50% duty cycle. The system includes means for producing a periodic signal having an interval half of a period of the noise creative vibration. The signal level of the rectangular signal is switched between HIGH and LOW levels alternately at timings of occurrence of the periodic signal. A crank angle sensor (1) produces the periodic signal. A rectangular wave generator circuit (11), in conjunction with a clock, produces a digital signal representing the rectangular signal. The digital signal is adjusted in phase (at 13) and amplitude (at 14), in response to engine load data and engine speed data, and an acoustic vibration whose frequency and amplitude are represented by the adjusted digital signal is reproduced by a speaker (34).

Abstract: The usual surveillance receivers are multiple heterodyne receivers which require high selection complexity. A simple heterodyne receiver is proposed which, with little selection complexity, unambiguously supplies spectral lines and has a wide dynamic range. To be able to unambiguously correlate the spectral lines (mirror frequencies), spectra are recorded at different oscillator frequencies. This is done successively in time - by means of one receiver - or simultaneously - by means of two receivers. The oscillator frequencies are offset with respect to one another in such a manner that the same frequency range is covered. The unambiguous correlation is obtained by subsequently correlating the spectra obtained. <IMAGE>
