Abstract: The invention is a diaphragm for electroacoustic transducers with the object of approximating the decay spectrum (postoscillation) of the diaphragm to the decay spectrum of the human auditory apparatus. For this purpose, the diaphragm is to be constructed from at least two cones with different aperture angles. The applicable aperture angles are 163, 157, 140, 114, 98, 82 and 66 degrees. A more natural and pleasant sound impression is produced by the coincidence of the characteristic oscillations of the ear with the characteristic oscillations of the transducer. Overview of the figures:   Figure 1: Cross-section of the diaphragm with the aperture angles alpha = 140 degrees and beta = 114 degrees     (1) = suspension   (2) = drive   (3) = diaphragm   Figure 2: Cross-section through a concave diaphragm with the aperture angles 114 degrees, 140 degrees and 157 degrees.

Abstract: On carrying out connected word recognition in compliance with a regular grammar and in synchronism with successive specification of input feature vectors of the input pattern, one of an n-th word (n) of first through third occurrence (n(1) to n(3)) is selected as the n-th word of selected occurrence in an i-th period in which an n-th input feature vector is specified. The n-th word appears as the first through the third occurrence in transition rules specified by the grammar. In the n-th period, distances are calculated, only for the n-th word of the selected occurrence, between the input feature vector assigned to the i-th period and reference feature vectors for the n-th word. In the i-th period, a recurrence value g(n, i, j) is calculated only for the n-th word of the selected occurrence under a boundary condition T(p, i-l) iteratively in correspondence to the reference feature vectors by using the distances calculated for the n-th word of the selected occurrence before the i-th period, where j represents each feature vector. The recurrence value for the n-th word of nonselected occurrence is estimated by using the recurrence value for the n-th word of the selected occurrence and the boundary conditions T(p, i-l)'s for the n-th word of the selected and the nonselected occurrence. The above-mentioned one of the n-th word of the first through the third occurrence is selected so as to have a minimum value of the T(p, i-l)'s.

Title: Improvements in process for planarizing an integrated circuit structure using low melting inorganic material
Inventor: MARKS JEFFREY
IPC: H01L21/31
Filed: 1991-02-08
Abstract: A planarizing process for planarizing an integrated circuit structure (14) in a CVD apparatus is disclosed using a low melting inorganic planarizing material which comprises depositing a low melting inorganic planarizing layer (34) such as a boron oxide glass over a layer of insulating material (20) such as an oxide of silicon, then dry etching the low melting inorganic planarizing layer to planarize the structure, and then depositing a further layer (40) of an insulating material to encapsulate any remaining portions of the low melting glass planarizing layer which may be hygroscopic. The method eliminates the need for separate coating, drying, and curing steps associated with the application of organic-based planarizing layers usually carried out outside of a vacuum apparatus. In a preferred embodiment, the deposition steps and the etching step are all carried out without removing the integrated circuit structure from the apparatus. In a particularly preferred embodiment, all of the steps are carried out in the same chamber of the apparatus. An additional etching step may be carried out after depositing the first insulating layer and prior to deposition of the planarizing layer to remove any voids formed in the insulating layer.

Abstract: A process for fabricating thin film transistors (TFTs) which comprises a two-step laser annealing process in which crystallization of the channel portion of a TFT is effected by irradiating the channel portion with an irradiation beam, for example from an excimer laser, and modification of the electric properties of the source and the drain regions of the TFT is effected by irradiating the source and the drain regions with an irradiation beam in a step independent of the step of crystallizing the channel portion. The process is carried out at low temperature and enables TFTs to be produced effectively and economically without risk of contamination by substrate impurities and with good expectation of a long operational lifetime.
