Patent CA-2076597-C (CA)
Inventor: REUTER DAVID C
IPC: B60K17/344
Filed: 1992-08-21
Granted: 2004-07-13
Abstract: The present invention is directed to an electronic actuator for use in a vehicle transmission such as a four wheel drive transfer case. In one preferred embodiment, the transfer case includes two separate electronic actuators, a range shift actuator which is utilized to effect shifting of the transfer case between high range, neutral, and low range drive positions, and a clutch actuator which is utilized to control engagement of a clutch between two wheel drive, automatic ("on demand" four wheel drive), and "part time" four wheel drive operating modes. The range shift actuator includes a rotary electric motor coaxially mounted relative to a rear output shaft of the transfer case, and a linear screw for translating the rotational movement of the motor shaft to selective axial movement of a range shift sleeve. The clutch actuator is similar to the range shift actuator except that, since the torque requirements necessary to bias the clutch are substantially greater than that necessary to effect the range shift, the clutch actuator includes additional gear reduction to enable the actuator to generate a sufficient axial force to fully engage the clutch. The actuators do not draw any current load after they have moved to their controlled positions and, because the linear screws can not be back driven, their previously set positions are maintained in the event of motor failure or power loss.

Title: Fixing assembly of a temperature responsive element and its fixing method
Inventor: MIZUTANI YASUKAZU
IPC: G01K1/14
Filed: 1993-05-03
Granted: 1996-08-06
Abstract: An object of the present invention is to provide a fixing method and assembly of a temperature responsive element capable of detecting variation in temperature of discharge cooling medium of a compressor exactly and rapidly and preventing the compressor from being burned.  A through hole is formed in a cover 6 which covers a path for discharge cooling medium of the compressor.  A plug is fixed to the through hole from the side of the path by a fixing member 13.  In this case, it is sealed airtightly by means of a pecking.  Lead terminal pins penetrating the plug is insulatively fixed in the plug airtightly.  Leads are connected to one end of the lead terminal pins projecting outside and the temperature responsive element is connected to the other ends of the lead terminal pins projecting on the side of the discharge path.  The temperature responsive element is disposed not to come into direct contact with a vessel and the cover of the compressor and is exposed to discharge cooling medium as a whole.   Consequently, the temperature responsive element can detect a temperature of the discharge cooling medium exactly and rapidly without influence of external disturbance such as heat from the outside and a path for suction cooling medium.

Granted: 1998-07-07
Abstract: Présentation d'une méthode et d'un dispositif utilisés pour produire une tension de sortie essentiellement constante à partir d'une cellule à combustible, peu importe les variations du courant de sortie. La tension et, de manière secondaire, le courant de la cellule sont au minimum déterminées périodiquement. La pression du gaz réactant dans la cellule à combustible est ensuite réglée pour que la tension nominale soit essentiellement maintenue. La température dans la cellule à combustible peut également être réglée pour maintenir la tension nominale de sortie. De plus, une méthode et un dispositif permettant de minimiser les pertes de puissance dues aux parasites dans un système de génération d'énergie électrique sont également présentés. La cellule est alimentée en gaz réactant par un compresseur qui est alimenté à son tour par la puissance parasite provenant de la cellule à combustible. La méthode est mise en oeuvre en déterminant le changement qu'a subi le courant de sortie de la cellule à combustible, et en modifiant un ou plusieurs de ces éléments : la pression, le débit-masse et le rapport d'utilisation du gaz réactant dans la cellule à combustible, ce qui a pour effet de modifier la quantité de puissance absorbée parasite provenant de la production d'énergie électrique nécessaire pour entraîner le compresseur.

Filed: 1994-12-30
Granted: 2005-06-14
Abstract: An acoustical tile composition based on a gypsum/cellulosic fiber composition which can replace all or a portion of the mineral wool normally present in acoustical ceiling tiles. The gypsum/cellulosic fiber composition is combined with a lightweight aggregate material and a binder to form a composition which is used in a water-felting process to manufacture acoustical ceiling tiles and panels. The preferred source of the cellulosic fiber is a composite gypsum/cellulose fiber material which is prepared by mixing the gypsum and cellulosic fiber material with sufficient water to form a dilute slurry which is then heated under pressure to calcine the gypsum, converting it to an alpha calcium sulfate hemihydrate. The resulting composite material comprises cellulosic fibers physically interlocked with calcium sulfate crystals.      Another source of both gypsum and cellulosic fibers is waste (scrap) gypsum wallboard. Expanded perlite is the preferred lightweight aggregate material.
