A shaving razor having a handle that defines a longitudinal axis, a shaving head that defines a transverse axis, a connector assembly, and a biasing element. The connector assembly couples the handle and the head so that the head can pivot upward and downward about its transverse axis and can also move toward and away from the handle with the transverse axis perpendicular to the longitudinal axis or oblique thereto. Preferably, the biasing element is separate and spaced apart from the connector assembly and biases the head into a rest position.

A fluid flow regulator of the present invention comprises in combination a stationary hollow duct housing having a first end and a second end through which fluid flows. The device also incorporates a movable member aligned concentric with the duct having an end essentially similarly shaped and sized to the first end of the housing. The member may be spaced apart from the duct so that fluid can enter the duct housing through an opening defined by the space between the end of the member and the first end of the duct, with the movement of the member serving to change the size of opening. The movement of the member is controlled by the movement of a float located within the duct. The position of the float can be preset by the operator of the invention so that when fluid flow into the duct is at a predetermined amount the float will remain stationary, and when the fluid flow increases above such predetermined level the float will be moved in the direction of the fluid flow and when fluid flow into the duct is below said predetermined amount, the float will move the member opposite the direction of fluid flow.

A die carrier assembly configured for use in a crimping machine. The assembly includes die carriers disposed in a circumferential arrangement and adapted for radially inward and outward travel. Each die carrier has oppositely-disposed circumferential extents that define circumferential gaps between adjacent pairs of the die carriers. Shoes are disposed radially inward from the die carriers and are adapted for radially inward and outward travel with the die carriers. The shoes travel radially inward and outward with the die carriers between positions in which the shoes define minimum and maximum openings, respectively, of the die carrier assembly. At least one of the shoes is disposed radially inward from one of the circumferential gaps between at least one adjacent pair of the die carriers. The circumferential extents of the adjacent pair of die carriers define interdigitated fingers that support the shoe when the die carrier assembly is at its maximum opening position.

One opening is formed in the insulating layer for every electrode group, the electrode group being constituted by at least two adjacent electrodes among the plurality of electrodes, and each of the plurality of electrodes is electrically connected to the corresponding one of the transistors through the opening.

The invention discloses a panoramic foldable vehicle sunroof sun shield, which comprises a sunroof frame, and a front sunroof sun shield assembly and a rear sunroof sun shield assembly which are arranged on the sunroof frame, wherein the front sunroof sun shield assembly comprises a first front-half sun shield and a first rear-half sun shield which are the same in length, and a front sun shield frame; the first front-half sun shield and the first rear-half sun shield can move forwards and backwards along a pair of first side guide rails; and when the first rear-half sun shield moves backwards, a first buffering bracket clinging to the first rear-half sun shield makes the first rear-half sun shield enter a first guide groove and a first guide rail end cover of the first side guide rail so that the first front-half sun shield is superposed below the first rear-half sun shield when backwards moving to the rear 1/3 section of the first side guide rail. The panoramic foldable vehicle sunroof sun shield of the invention not only can increase the opening size of the sun shield, but also can improve the rigidity and strength of the sun shield.

A button-key device includes a casing having an opening extending from a position near one end to a position near another end of the casing, and a pair of strength-maintaining projections projecting in opposite directions from the ends, respectively; a first key-top unit including a projecting section, an extended portion provided at an end of the projecting section facing one of the strength-maintaining projections, and flanges; a second key-top unit including a projecting section, an extended portion provided at an end of the projecting section facing the other strength-maintaining projection, and flanges; a first water-blocking sheet provided on a bottom of the first key-top unit; a second water-blocking sheet provided on a bottom of the second key-top unit and having an overlapping portion overlapping the first water-blocking sheet; and a pressing portion provided on the casing and pressed against the overlapping portion.

Continuous cross sectional profile guide tracks in an outer sliding sunroof/moonroof are provided where both the front and rear mechanism or mechanism links travel fore/aft in the same channels as each other and have fore/aft travel that is limited only by vehicle architecture.

A selected range arc settable spray nozzle with pre-set table precipitation rate in which the arc of coverage adjustment is coupled to an upstream flow throttling valve. As the arc of coverage is adjusted, the opening of the upstream flow throttling valve is proportionally adjusted to maintain the precipitation rate substantially constant independent of arc of coverage adjustments. Upstream flow throttling achieved by use of pre-selected number of larger slots for desired flow whose opening area is varied as the arc is being set. The precipitation rate is set by adjusting the throttling valve to provide the desired flow rate for the maximum arc of coverage setting. A pressure compensating valve may also be provided.

The invention provides a forming method of a tungsten electrode. The method comprises the steps of: forming a first opening in a semiconductor substrate, forming a tungsten layer respectively on the side wall and the bottom part of the first opening and the surface of the semiconductor substrate, then removing the tungsten layer on the surface of the semiconductor substrate, and at least reserving a part of tungsten layer on the bottom part of the first opening; and then using the residual tungsten layer in the first opening as a core layer, and continuously forming tungsten to fill the first opening. After tungsten on the surface of the first opening is removed, tungsten cannot be formed on the surface of the semiconductor surface in the tungsten forming process with the residual tungsten layer in the first opening used as the core layer, so that the first opening is prevented from being blocked by tungsten on the surface of the semiconductor substrate, and the problem that reaction gas fails to enter the first opening is solved, the number and size of gaps in tungsten formed in the opening are further reduced, and the performance of the tungsten electrode is improved.
