Title: Limiteur de debattement pour volet de godet d'excavatrice
Inventor: GATTER DOUGLAS C
IPC: E02F9/22
Filed: 1997-04-09
Granted: 2005-08-09
Abstract: On utilise un limiteur de débattement pour atténuer le balancement du volet (36) d'un godet (30) d'excavatrice et ce, afin d'éviter que ce volet (36) ne soit endommagé par de fréquentes fermetures brutales. Le limiteur (60) comporte un boîtier (61) monté sur le godet et un arbre (70) pourvu d'un montage à pivot dans le boîtier et relié à un volet (36). L'arbre (70) tourne lorsque ce volet (36) s'ouvre. Dans le boîtier (61) est ménagée une cavité cylindrique (72) entourant l'arbre. Cette cavité (72) est subdivisée en deux volumes (72B, 72A) par une barrière (82) et un bras de balayage (80) sur l'arbre (70). Ce bras de balayage (80) force le passage d'un fluide hydraulique (94) à travers un orifice (101) situé entre les volumes (72B, 72A) lorsque l'arbre (70) est en rotation. Il possède également des fermetures d'extrémité (90) obturant les parois d'extrémités (68, 66) de la cavité (72). Ces fermetures d'extrémités (90) sont poussées vers l'extérieur par la pression hydraulique lorsque le volet (36) se ferme. Un clapet anti-retour (102) permet au fluide hydraulique (94) de contourner l'orifice (101) lorsque le volet (36) s'ouvre. Ce limiteur (60) nécessite moins d'entretien que ses prédécesseurs du type à friction.

Abstract: A method of stamping and punching at several stations, an opening in a vehicle rood panel to provide for sunroof installation is described. A preformed recess is stamped into the top section of the panel to define a perimeter for a sunroof opening. The stamping of the preform comprises locating the roof panel in a stamping press beneath a press die where the die is aligned with the perimeter of the desired position for the sunroof opening.  The preform recess is stamped in the panel where the preform is characterized by having a first bend which defines the opening perimeter and comprises rounded corner portions interconnected a front, rear and two side edges. A downwardly extending flange which becomes a sidewall of the sunroof opening is provided and has a length at least equal to the depth of a sealed portion of the sunroof panel and a second bend extending opposite to the first bend for interconnecting flange to the base portion of the recess. At the subsequent stations the underside surface of the flange of the preform is used to locate the panel for further processing. Preferably, at a subsequent processing station an apparatus is provided for bending lip portions of the depending flange to facilitate insertion of the sunroof. The apparatus has floating backup blocks and stacked stripper block and die block to locate the opening and effect bending of the flange without distorting the precise location of the flanges to ensure a seal with the sunroof panel installation.

IPC: A42B3/14
Filed: 1998-04-06
Granted: 2007-06-05
Abstract: The present invention provides an adjustable headband for protective headgear with a ratchet mechanism having different resistances.  The adjustable headband utilizes a ring gear assembly (300) having a plurality of radially projecting teeth (325) thereon. Each of the projecting teeth (325) of the ring gear assembly (300) has a first tooth side and a second tooth side which is different from the first tooth side. For example, each tooth of the ring gear assembly preferably has a first tooth angle on the first tooth side and a second, different tooth angle on a second tooth side. A spring assembly (150) having at least one spring tooth (155) projecting radially therefrom is connected to the adjustment knob (100). The spring assembly (150) is positioned such that the at least one spring tooth (155) meshes with the teeth (325) of the ring gear assembly (300) to provide resistance to the rotation of the adjustment knob (100). Because the first tooth angle of the ring gear assembly (300) is different from and preferably less than the second tooth angle of the ring gear assembly (300), it is substantially easier to rotate the adjustment knob (100) in the direction of tightening the headband than in the direction of loosening the headband.

Abstract: A control panel assembly of a microwave oven which is easy to use, including:  a front panel section having first and second cooking mode single-functional buttons comprised of a plurality of single-functional buttons for first and second cooking modes of the microwave oven, and a slot formed on the middle portion of the front panel section between the first and second cooking mode single-functional buttons; a movable switch disposed on the front panel section which is moved laterally along the slot of the front panel section; and a mode shifting switch for shifting cooking modes to the first and second cooking modes by the movement of the movable switch, wherein the first and second cooking modes are automatically selected by the movement of the movable switch, and the cooking mode single-functional button of the selected mode is exposed outward for pressing by a user. Accordingly, by simply moving the movable switch in a lateral direction, the cooking modes of the microwave oven are automatically selected. Also, the cooking mode single-functional button of the selected cooking mode is exposed, while the single-functional buttons of the unselected cooking mode are blocked by the movable switch. Accordingly, since there is a reduced number of exposed functional buttons, the appearance of the microwave oven is simple and clean. Further, by using the single-functional button for frequently cooked foods, the use of the control panel assembly becomes much easier.

Granted: 2003-04-15
Abstract: A Ge-added SiO2 thin film (12) is formed on a glass substrate (10), and a metal film (14) is formed thereon (S11 to S13). By etching the metal film (14), a pair of electrodes (14a, 14b) mutually opposed at a predetermined interval is formed (S14). An insulating thin film (16) is formed on the insulating film (12) and the electrodes (14a, 14b) (S15). While applying ultraviolet radiation, a high voltage is applied between the electrodes (14a, 14b) to perform ultraviolet excitement polling to impart an optical nonlinearity to a channel region (18) (S16). By controlling the voltage application to the channel region (18) having the optical nonlinearity, the light transmitted through the channel region (18) is controlled. Thus, an optical nonlinear waveguide for propagating single mode light is formed on a glass substrate.
