Title: Reseaux de cordes musicales
Inventor: GAUTHIER CLAUDE
IPC: G10D3/12
Filed: 2004-05-12
Granted: 2007-12-18
Abstract: Le principal objectif de la présente invention est de décrire et de mettre en pratique un phénomène par lequel une corde - c'est-à-dire une ligne droite simple d'une certaine tension, d'un certain diamètre et d'une certaine longueur qui produit une vibration - peut, lorsqu'elle est associée à un réseau d'une pluralité de cordes interreliées en un ou plusieurs points de jonction et qui en rayonnent, créer une nouvelle entité appelée « réseau de cordes » qui possède de nouvelles propriétés vibratoires. Lorsque la vibration se déplace, sous la forme d'une onde, sur le premier segment du réseau, elle se divise au premier point de jonction rencontré entre la première corde et au moins une autre corde, mais de préférence avec deux cordes ou plus. Le transfert de l'énergie de l'onde initiale aux autres cordes du réseau les fait vibrer à leur tour. Lorsque l'onde des autres cordes revient au point de jonction, un autre transfert d'énergie a lieu, si bien qu'une partie des vibrations, modifiée par les propriétés de chacune des cordes, créé un modèle de vibration qui peut être ajouté ou soustrait, ce qui donne naissance à des modèles ondulatoires complexes.

Granted: 2012-02-14
Abstract: La présente invention concerne un dispositif de fixation de skis qui permet la fixation des bâtons de ski (6a, 6b) aux skis (7). En général, le transport simultané d'une paire de skis (7) et d'une paire de bâtons de ski (6a, 6b) est une tâche difficile qui nécessite l'utilisation des deux mains. Ainsi, il s'avère difficile de tenir en même temps des skis (7), des bâtons de ski (6a, 6b) et d'autres objets ou de se tenir à des barres de retenue dans des bus et des cabines de téléphérique au cours du transport des skis (7). Les éléments rapportés utilisés dans l'état de la technique pour remédier à ce problème présentent l'inconvénient que les éléments utilisés pour le maintien des bâtons de ski doivent être conservés séparément lorsqu'ils ne sont pas utilisés et sont peu pratiques d'utilisation. L'invention permet de palier cet inconvénient grâce à la mise en place de façon durable d'un dispositif de fixation (1a, 1b) contre le bâton de ski (6a, 6b), au niveau duquel une pièce de blocage en forme de fourche (5a, 5b) est fixée de façon à pouvoir s'escamoter, une paire de skis (7) pouvant être bloquée entre les branches (9) de ladite pièce. La mise en place d'une pièce de blocage en forme de fourche (5a, 5b) respectivement sur les deux côtés d'une paire de skis (7) permet non seulement de fixer les bâtons de ski (6a, 6b) aux skis (7), mais aussi aux skis (7) d'être maintenus ensemble. De cette manière, il est possible de se servir d'une seule main pour transporter les skis (7) et les bâtons de ski (6a, 6b).

Title: Powder molding die apparatus and method of molding for obtaining powder molding product
Inventor: NAKAI TAKASHI
IPC: B30B11/02
Filed: 2004-03-26
Granted: 2011-05-24
Abstract: A surface treatment layer 11 is formed on a surface 10 of a through-hole 1 so that the surface 10 has an angle X of contact with solution L which is smaller than an angle Y of contact of a die 2 per se with the solution L. When the solution L  is applied, the wetting action of the solution L relative to the through-hole 1 is improved so that the solution L can be extended over the surface treatment layer 11, eventually over the entire surface of the through-hole 1. Consequently, the entire surface thereof can be formed with a crystallized layer by performing water evaporation. As a result, molding at higher temperature can be realized, and high-density compacts can be stably obtained.  Further, the solution L in which the lubricant is dissolved in a solvent into a homogeneous phase, is applied to a molding portion 1A, and then evaporated to thereby form crystals thereon, thus forming the crystallized layer.

Abstract: A method for providing network synchronization with a unified messaging system (104) is provided. The method includes receiving and storing (300) message data, such as voice data, for a specified recipient. An enhanced e-mail message is generated (302) for the recipient. The message, which is in hypertext mark-up language (HTML) format, includes the message data and a synchronization link that points to a web server (128). The message is sent (304) to the recipient through an e-mail server (108) corresponding to an e-mail client (110) associated with the recipient. When the client downloads the message from the server (108) and renders the HTML, the synchronization link is fetched. As a result, the web server (128) receives (306) a hypertext transfer protocol (HTTP) request from the client (110) based on the message and provides (308) network synchronization based on that HTTP request.
