Title: Alimentation de decoupage de type rcc
Inventor: SHIMAMURA TAKASHI
IPC: H02M3/28
Filed: 1997-04-10
Abstract: Alimentation à découpage de type RCC comprenant un dispositif de découpage principal 9 mis sous tension et hors tension en alternance afin de faire circuler un courant de découpage dans un enroulement primaire 31 pour transférer du primaire au secondaire l'énergie nécessaire au retour du spot. Un circuit d'amortissement 5a-5c comprend un condensateur d'amortissement 7 et un dispositif de découpage auxiliaire 3 qui sont branchés en série entre eux et en parallèle à l'enroulement primaire 31. Lorsque le dispositif de découpage auxiliaire 3 est mis sous tension par un enroulement auxiliaire 4 alors que le dispositif de découpage 9 est hors tension, l'auxiliaire charge le condensateur d'amortissement 7 avec l'énergie stockée dans une inductance de dispersion de l'enroulement primaire 31, puis agit sur le fonctionnement du premier quadrant de sorte que ledit condensateur 7 est déchargé afin de faire circuler un courant dans l'enroulement primaire 31. Le courant transfert l'énergie à l'enroulement secondaire 32 ou charge un condensateur de filtrage 21 du côté primaire afin de transférer l'énergie à un dispositif de redressage et de filtrage 18 sur le côté primaire. Étant donné qu'une surtension n'est pas appliquée au dispositif de découpage principal 9 et que l'énergie stockée dans l'inductance de dispersion n'est pas perdue, l'alimentation de découpage de type RCC 2a-2c produit peu de bruit et est très efficace.

Title: Brake control valve
Inventor: GAWLICK DIETER
IPC: B60T13/14
Filed: 1998-05-13
Abstract: A vehicle brake control valve includes a piston assembly which is movable a stepped cylindrical bore of a valve housing in response to an actuating force against the force of a spring. The piston assembly includes port control edges which control communication between a brake pressure chamber which can be connected to the vehicle brakes, areservoir, and a pump. Both the pump and the actuating force contribute to the brake pressure which builds up in the brake pressure chamber. The piston assembly includes an actuator piston and an annular piston that sealingly slides within a larger portion of the stepped bore. After the actuator piston moves a pre-set distance (H) it carries with it the annular piston. The annular piston, the actuator piston and a wall of the larger diameter portion of the stepped bore enclose a fill pressure chamber which is separated from the brake pressure chamber to achieve two-stage pressure build-up during manual braking (emergency braking) when the pump is inoperative. The fill pressure chamber and the brake pressure chamber are connected to each other via a pressure reducing valve which opens towards the brake pressure chamber.

Patent CA-2244688-A1 (CA)
Title: Method for generating moisture, reactor for generating moisture, method for controlling temperature of reactor for generating moisture, and method for forming platinum-coated catalyst layer
Inventor: MORIMOTO AKIHIRO
IPC: C01B5/00
Filed: 1997-01-27
Abstract: The invention further reduces a size and cost of a reactor for generating water from oxygen and hydrogen, provides high-purity water in an amount necessary for practical use safely, stably and continuously, and allows a platinuin-coated catalyst layer formed on an inner wall of a reactor body to maintain high catalytic activity over a long period of time. Specifically, the reactor comprises a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, has a gas-diffusing member provided in an internal space of the body, and has a platinum coating on an internal wall surface of the body.  Hydrogen and oxygen fed from the inlet is diffused by the gas-diffusing member and then comes into contact with the platinum coating to enhance reactivity, thereby producing water from hydrogen and oxygen. A temperature of the reactor for generating moisture, wherein hydrogen is reacted with oxygen at a high temperature to generate moisture, is held to be below an ignition temperature of hydrogen or a hydrogen-containing gas so that hydrogen is reacted with oxygen while preventing explosive combustion of hydrogen and oxygen. The platinum-coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or nitride on the wall surface, and forming the platinum coating on the barrier coating.

Patent CA-2253491-A1 (CA)
Title: Compacted-powder opposed twin-helical gears and method
Inventor: HINZMANN GERD
IPC: B22F3/02
Filed: 1997-05-09
Abstract: A multiply-acting powder metal press is disclosed for making green form double helical gear compacts. The press has inner and outer lower punches, and an upper, outer punch. The upper and lower outer punches have left hand and right hand external helical profiles as chosen to produce a desired helical gear. The punches co-operate with left hand and right hand helical dies carried by the press about the punches. The helical faces require that the dies rotate relative to the punches during operation.      A cam and roller mechanism may drive this rotation.      The compact forming process commences with an open position in which powder is introduced to a vacant lower die cavity. The upper portions of the press advance downward to close the cavity. All pans of the press except the lower inner, or transfer, punch then move downward at the same speed to transfer powder to the extremities of the cavity. When transfer is complete both lower punches may be stopped, while the upper punches continue to advance. The dies advance at half the speed of the upper punches, rotating partially as they do so. Once the powder reaches its compacted density the upper and lower punches cease motion, but their dies continue to tum, separating themselves and compressed part. Finally, the part is ejected and the press returns to the initial condition.

Inventor: HARTLEY WILLIAM R
IPC: B21D39/02
Filed: 1998-11-16
Abstract: Improved method and apparatus for interlocking hemmed together edges of inner and outer vehicle body panels with an improved interlock joint. The inner panel blank is conventionally draw stamped to a desired size and shape and provided with PLP holes. An inner panel and hardware sub-assembly is then built up by welding a plurality of conventional hardware components to the inner panel. Then a plurality of interlock holes are formed in the inner panel border by a piercing tool moving through the border from the outboard side to its inboard side while the inner panel is held located in a predetermined orientation relative to the piercing tool travel by clamps and PLP pins registered in the PLP holes. Then the inner panel subassembly is married to the outer panel and transferred to a hemming station and again precisely clamped and positioned by PLP pins so that hemming press gates are operable for hemming the flange lip of the outer panel over the inner panel border. The final hemming steel of each gate carries staking punches driven by an actuator carried on the pre-hemming steel and that permanently interlock the panels by permanently deforming hole-registered portions of the final hemmed flange lip into the associated interlock hole. This results in a securely joined and precision assembly of the inner and outer panels. An improved interlock joint is thereby formed for interlocking hemmed together edges of inner and outer vehicle body panels. The hole piercing punch, in shearing from the outboard to the inboard side of the inner panel border, leaves cold worked upset material slightly raised inboard, rather than outboard, around the pierced interlock hole margin. The hemming press staking punch strikes a registered portion of the outer panel flange lip to deform it into locking engagement with the associated interlock hole, and in so doing, the upset material is flattened and worked into embedment into the interior surface of the outer panel flange lip thereby avoiding creating read through problems on the outer panel.
