A push back storage rack system for storing multiple loads in a single inclined cart lane. Each lane contains at least two wheeled carts, each cart being capable of receiving and storing multiple pallet loads. The carts are vertically spaced so that they can freely slide underneath each other when unloaded. Beginning with the first or lowest level cart in the system, each successively higher cart is also wider and longer than the cart immediately beneath it. The carts are positioned on at least one but potentially two pairs of rectangular tracks or tubes, each tube being capable of supporting two or four individual carts, depending on how the carts are constructed and installed on the tubes. The tubes are mounted on an incline away from a loading end of each lane so that when loads are placed on or are removed from a lane, the carts are biased toward the loading end of the lane by the force of gravity. Each tube has a single, planar upper support surface which has inside and outside edges. The wheels of each cart ride only on either the inside or outside edges of the tubes on which they are mounted, allowing more than one vertically spaced cart to occupy the same tube.

A modular fuel injector that includes a coil group subassembly and a valve group subassembly. The coil group subassembly is independently testable. The valve group subassembly is independently testable and includes a tube assembly having a longitudinal axis extending between a first tube end and a second tube end, and a seat assembly disposed in the tube assembly proximate the second tube end. The seat assembly includes a flow portion and a securement portion. The flow portion extends along the longitudinal axis between a first surface and an orifice disk retention surface at a first length. The flow portion has a seat orifice extending therethrough and an orifice disk coupled to the orifice disk retention surface so that the orifice plate is aligned in a fixed spatial orientation with respect to the flow portion. The securement portion extends along the longitudinal axis away from the orifice disk retention surface at a second length greater than the first length. A method of maintaining a fixed spatial orientation and dimensional symmetry of at least one of the seat and orifice disk in the valve subassembly is disclosed.

A mounting assembly of semiconductor packages is revealed, primarily comprising at least a semiconductor package having a plurality of external terminals, a package carrier, and solder paste. The solder paste joints the external terminals to the package carrier. According to the distance to a central line on a substrate of the semiconductor package, the external terminals are divided into at least two different groups. In one of the embodiment, different groups of the external terminals are bumps with non-equal heights to achieve a uniform standoff plane to compensate the warpage of the substrate. The predicted substrate warpage can be compensated without causing any soldering defects. In another embodiment, a plurality of compensating bumps are selectively disposed on one group of the external terminals with larger stacking gaps.

A blow molding device capable of securely holding a built-in part in a prescribed position in an interior of a blow molded article with a compact equipment. The blow molding device includes a blow mold and a built-in part holding unit. The built-in part holding unit includes a holding rod adapted to hold the built-in part and arranged to freely advance and retreat to be removed from the blow mold. The blow mold includes a slide core in each of two mold members so as to freely advance and retreat relative to a cavity of the blow mold, and a drive control pin in each of mating faces of split two mold members, and the drive control pin and the slide core are linked with a linking member. The slide core is driven with the drive control pin such that when the blow mold is closed, the slide core retreats from an interior of the cavity to a molding surface defining the same at the same speed as the closing speed of the blow mold.

An ergonomic, power-assisted lifting-lowering unit for lifting or lowering a user, such as a disabled person. The lifting-lowering unit includes a body-holder, adapted to firmly hold/support at least at one body member/section of the torso of the user; a lifting-lowering-mechanism; a motion and force transmitting mechanism; and a power activator. The lifting-lowering-mechanism includes a power actuator that is operatively engaged with the body-holder, at preconfigured locations. The power activator activates the power actuator to thereby set in motion the motion transmitting mechanism that causes the body-holder to move in a path closely approximating to the movement of the femur bones, or a in path parallel thereto, when the user is moving between a standing position and a sitting position, the knees being the proximal center of the pivotal motion of the femur bones of the user.

A corner joint between two frame lineals of a pultruded window frame is defined by inserting a leg of a corner member into a hollow interior of each lineal and attaching the legs to the lineals by adhesive. Each leg has a plurality of surfaces thereof each having a first portion at the corner which lies closely adjacent a corresponding surface of the first lineal and a second portion, at the end of the first portion remote from the corner which tapers inwardly away from the corresponding surface of the first lineal such that a spacing therebetween increases in the direction away from the corner. The adhesive is applied to the tapered portion and the taper acts to force the adhesive along the leg to the first portion and to the ends of the lineals where the excess can be wiped away.

In case a fixing speed is lower than a transferring speed, the individual conveyor units are controlled such that, while a downstream conveyor unit (61) is conveying a sheet (S1) being fixed at the same speed (V2) as the fixing speed, an upstream conveyor unit (60) may convey the succeeding sheet (S2) at the same speed (V1) as the transferring speed. As a result, the spacing of the two sheets in a fixing unit (9) can be sufficiently narrowed to improve the image forming efficiency. Moreover, the transferring speed need not be decelerated according to the fixing speed. It is, therefore, possible to prevent the deterioration in the image quality and to shorten the image forming time period of the first sheet.
