Title: String support for stringed instrument
Inventor: TURNER WILLIAM T
IPC: G10D3/04
Filed: 1993-06-29
Abstract: String Support For Stringed Instrument William T. Turner ABSTRACT     A nut (30) and/or saddle (20) supports the strings (14) of a stringed musical instrument (10) allowing essentially fully unrestricted movement of the strings, both forward and background within the nut or saddle in order to maintain the proper pitch tuning of each string. Each string is retained at a fixed position at the nut or saddle, but allowed to move freely from these fixed positions when the strings are in motion such as when being tuned.  A pair of freely-rotatably ball bearings (34a and 34b) are positioned in a countersunk pocket aperture 33 in the nut housing (32) and/or saddle housing (60) and in the case of the former, are positioned immediately juxtaposed to a pressure pad (413 for dampening each string from vibration between the nut assembly and the instrument tuner mechanism.  A retainer (42) retains each pair of balls (34a and 34b) in the pocket aperture (33).

Filed: 1993-01-15
Abstract: Method and Device for Determining the Tensile Force for Stringing Rackets Abstract In a method for determining the tensile forces for stringing rackets, the stringing areas of which comprise parallel lon-gitudinal strings and cross strings parallel to each other, the tensile force KPL for the longitudinal strings KPL is de-termined as a function of the length LL of the longest longi-tudinal string between the racket head and frame yoke in the stringing area and the tensile force KPQ of the cross strings as a function of the length of the longest cross string LQ in the stringing area, of the length of the longest longitudinal string LL and the tensile force KPL.  The tensile force KPL is multiplied by factors for the string number of the longi-tudinal strings SZL, the tension level SN, the stroke type ST and the frame hardness RH.  The tensile force KPQ is multi-plied by factors for the string number of the cross strings SZQ and the stroke type ST. The factors are stored and can be selected by the user.  The device for determining the ten-sile forces for stringing rackets comprises a display unit, a microprocessor and a keyboard, wherein the keyboard has keys for directly calling in the factors for the string number of the longitudinal strings SZL and/or the string number of the cross strings SZQ and/or the tension level  SN and/or the stroke type ST and/or the frame hardness RH and for inputting the values of LL, LQ, SZL and SZQ.

Title: Circuit et methode de detection d'erreurs
Inventor: OKADA TOMOYUKI
IPC: H04L1/00
Filed: 1994-05-03
Abstract: L'invention est constituée par un circuit de détection des erreurs pour un récepteur numérique et par la méthode de détection connexe. Le récepteur numérique en cause est utilisé dans un mode de communication AMRT dans lequel des signaux modulés par déplacement de phase différentielle en quadrature sont produits, comme dans le système téléphonique numérique sans fil japonais. Les circuits de détection des erreurs détectent les périodes durant lesquelles un bruit ou un autre type de distorsion excessif est introduit dans une ou plusieurs séquences d'un signal transmis durant un ou plusieurs créneaux temporels du mode de communication AMRT. Un récepteur doté du circuit de détection des erreurs de l'invention ne décode pas les parties du signal reçu où un nombre excessif de séquences contient un bruit ou un autre type de distorsion excessif. Ainsi, la dégradation de la qualité audio du signal reproduit par le récepteur doté de ce détecteur d'erreurs est minimisée.
