Patent CA-2279708-A1 (CA)
Inventor: MIKI KAZUSHIGE
IPC: H04M1/65
Filed: 1999-08-04
Abstract: An object of the invention is to provide excellent operability in receiving a textual message. A call set-up signal representing that a textual message from a transmitter side is transmitted, and a textual message are received by a transmission and reception circuit without performing any response to the incoming call, and the received textual message is stored in a memory. Notification means performs a notification operation by the call set-up signal being received.      The receiver can read the message by viewing display means.      Thus, the message from the transmitter can be received in real time. Since it is unnecessary to respond to an incoming call, the receiver side is not charged. An incoming call operation is performed by operating a response button, and speech processing can be performed by use of a microphone and a speaker.

IPC: A63F3/06
Filed: 1998-05-13
Abstract: La présente invention concerne une carte (5) comporte un couche (40) s'éliminant au grattage destinée à cacher des symboles imprimés. La carte est fabriquée de manière que la couche de grattage soit sélectivement retenue sur la carte, laissant apparaître soit des symboles, soit un fond comportant des symboles lorsque la couche de grattage est éliminée. L'adhésion sélective des matériaux de la couche de grattage à la carte est obtenue par incorporation à la carte, entre le substrat (10) et la couche de grattage, d'une couche de séparation transparente (30) portant des motifs destinés à former des symboles. Lorsque le matériau est appliqué sur la carte pendant la fabrication, il est amené soit à adhérer directement sur le substrat pour former des symboles, soit à adhérer sur le substrat pour former le fond sur lequel sont représentés les symboles, en fonction du mode choisi pour appliquer la couche de séparation. Lorsqu'un joueur gratte la couche de grattage, celle-ci se détache de la couche de séparation et reste collée au substrat de manière à former soit les symboles, soit le fond.

Title: Ion-conducting composite which is permeable to matter, method for producing said composite, and use of the same
Inventor: HORPEL GERHARD
IPC: B01D46/24
Filed: 1999-03-20
Abstract: The invention relates to an ion-conducting composite which is permeable to matter, to a method for producing an ion-conducting composite which is permeable to matter, and to the use of this composite in various processes. Membranes or ion-conducting materials are used for various chemical and physical processes, e.g., electrolysis, electrodialysis. The membranes used are often polymer-based. These polymers are relatively non-resistant to solvents and high temperatures. Therefore, the aim of the invention is to provide an ion-conducting composite. The inventive composite consists of inorganic constituents or at least mainly of inorganic constituents, and is characterised in that it is very stable in relation to acids and high temperatures. According to the invention, ion-conducting materials or materials which will be ion-conducting after an additional treatment are added to a composite which is permeable to matter during production. Alternatively, the finished composite is treated with said materials.

Title: Bi-directional spring holder assembly for an actuator
Inventor: JORGENSEN GREGORY A
IPC: H01H3/30
Filed: 1998-08-05
Abstract: An actuator having a bi-directional spring holder assembly is disclosed. The assembly has a substantially cylindrical housing (42) having a projection (60) formed on a rim of its cylindrical wall (56). The projection (60) is provided with first and second abutments (62, 64) facing in opposite directions along the circumference of the rim (58). A spring (70) is mounted around a shaft which passes through a longitudinal axis of the housing. A first, internal spring end (72) is engaged to the shaft while a second, external spring end (74) projects radially outward of the cylindrical wall (56). The assembly also includes a spring cover (80) provided with a cover abutment (84) which similarly projects radially outward of the cylindrical wall (56). When the holder assembly is assembled, the spring (70) is coiled and the cover abutment (84) pushes against the projection's first abutment (62) while the external spring end (74) pushes against the second abutment (64). The actuator housing is provided with a wall member (48), one side of which forms a stop for the cover abutment (84), while the other side serves as a stop for the external spring end (74). When the gear train is driven, one of the cover abutment (84) and the external spring end (74) abut a corresponding stop, and the entire housing (42) rotates with the output lever, causing the spring to coil. The coiled spring then provides a restoring force, returning the output lever to the neutral position.

Title: Method of manufacturing hot dip coated metal strip
Inventor: SUGANO TAKAHIRO
IPC: C23C2/00
Filed: 2000-06-14
Abstract: A method of manufacturing a hot dip coated metal strip includes the steps of depositing a molten metal coating solution on the surfaces of the metal strip by continuously dipping the metal strip in a coating bath, lifting the metal strip at a constant speed while supporting it with a pair of upper and lower support rolls for clamping the surfaces of the metal strip in the coating bath, adjusting the coating weights of the molten metal deposited on the surfaces of the metal strip by wiping the molten metal with gases from gas wiping nozzles disposed above the surface of the coating bath, and advancing the metal strip while supporting it with a pair of upper and lower touch rolls for clamping the surfaces thereof, wherein the metal strip is advanced by setting the distance L between the upper support roll disposed in the coating bath and the lower touch roll disposed outside the coating bath within the range determined by a formula L <= 80 × T × W2/V, where L: distance between the upper support roll in the coating bath and the lower touch roll outside the coating bath (mm), V: line speed of the metal strip (m/min), T: tension imposed on the metal strip (kgf/mm2), and W:     target coating weight per one side of the metal strip (g/m2). According to the invention, the stable quality of the metal strip can be obtained by reducing the variation of the coasting weights of the molten metal deposited on the surfaces of the metal strip by reducing the variation of the coating weights of the molten metal deposited on the surfaces of the metal strip at all times regardless of the change of the operating conditions under which continuous hot dip galvanizing operation is carried out.  Further, a coating cost can be greatly reduced by preventing the excessive deposition of the molten metal.
