An array of a pillar-type nonvolatile memory cells (803) has each memory cell isolated from adjacent memory cells by a trench (810). Each memory cell is formed by a stacking process layers on a substrate: tunnel oxide layer (815), polysilicon floating gate layer (819), ONO or oxide layer (822), polysilicon control gate layer (825). Many aspects of the process are self-aligned. An array of these memory cells will require less segmentation. Furthermore, the memory cell has enhanced programming characteristics because electrons are directed at a normal or nearly normal angle (843) to the floating gate (819).

A novel apparatus and method of reduced power consumption for battery backup operation of a communication device such as a cable modem. When the cable modem senses a failure of the external power source it requests from the cable head-end to switch from multi-channel DOCSIS 3.0 operation to single-channel DOCSIS 2.0 operation. In response to approval by the cable head-end, the cable modem shuts down multi-channel circuits in the PHY such as the wideband analog to digital converter (ADC) which is normally used during multi-channel operation. In its place, it activates narrowband circuitry such as a narrowband ADC which consumes far less power. Tuner filter circuits are also swapped to match the reduced bandwidth requirements of battery backup operation. To further reduce power, the narrower bandwidth requirements during battery backup operation permit the linearity of a programmable gain amplifier (PGA) in the upstream path to be reduced.

High reliable copper interconnects are formed with copper or a low resistivity copper alloy filling relatively narrow openings and partially filling relatively wider openings and a copper alloy having improved electromigration resistance selectively deposited in the relatively wider openings. The filled openings are recessed and a metal capping layer deposited followed by CMP. The metal capping layer prevents diffusion along the copper-capping layer interface while the copper alloy filling the relatively wider openings impedes electromigration along the grain boundaries.

A scissor lift includes an energy storage device that stores energy as the payload is lowered, and provides further lift to the payload as the payload is raised. This allows the scissors to achieve a support angle of up to 180° between the two arms (down to 0° between the screw drive and the lowest arm of the scissors), making the inventive scissor lifts considerably more compact than prior art lifts. The energy storage device is preferably a helical wire spring, but can alternatively be any suitable spring, piston, or even an elastomeric mass. Side to side movement of the scissors arms can be restricted using a thrust bearing with hardened washers at the inter-arm pivot, and / or a guided connector that transmits motive force to the scissors.

A packer tool has safety devices to prevent premature and reverse setting and release operations. The safety devices are independent of shear-pin safety systems. Confined annular segments prevent a setting actuator piston from moving absent tool-setting hydraulic pressure. The setting pressure first moves a cylinder in an opposite direction to unroof the segments allowing them to exit confinement and free the piston to set the packing and the anchor slips. Release safety pins extend radially inward from a packing-holder collar into short slots formed on a mandrel surface, preventing the mandrel from being turned. Previous set motion causes the pins to leave the slots thereby freeing the mandrel to turn only after the tool has been set. A third safety device comprises an expanded ring which is dragged by the release cone during release motion until it lodges in a circumferential groove in the mandrel, locking against reverse movement.

The invention relates to the protection of structural systems such as apartment houses against dynamic loading caused by earthquakes, wind, traffic etc. When a frame structure is excited by a horizontal external force, the girders starts to displace horizontally. If such displacements are large or if they occur periodically they may have serious impact on the conditions of the structure and may cause severe damages or even result in a collapse. The present invention relates to a very simply designed and easily produced damper with two members being interconnected in a rotational joint. By means of the arrangement of the damper in the structural system, displacement occurring in the system is transferred to the members being forced to rotate in relation to each other. Frictional resistance between the two members is dampening the rotational movement and thus the displacement in the system. The invention further relates to a device wherein the frictional resistance may be varied dynamically based on the displacements occurring in the system.

Various clutch and cord configurations may be used to achieve a desired amount of directional friction. The directional friction prevents the window covering from falling under its own weight.

In a hybrid vehicle equipped with an engine and a motor that are connected to a driveshaft linked to an axle via a gear mechanism, on condition that a torque demand Tr* required for the driveshaft is lower than a preset reference torque level Tref (step S220) and that a vehicle speed V is lower than a preset reference speed level Vref (step S230), the drive control of the invention idles the engine (step S240) regardless of a stop request of the engine (steps S120 and S210). This arrangement effectively reduces the potential for backlash or gear rattle in the gear mechanism. On condition that the vehicle speed V is not lower than the preset reference speed level Vref (step S220), on the other hand, the drive control of the invention stops the operation of the engine (step S250) in response to the stop request of the engine (steps S120 and S210) even under the torque demand Tr* of lower than the preset reference torque level Tref (step S230). This arrangement desirably enhances the energy efficiency of the hybrid vehicle.

It is, accordingly, an object of the present invention to provide an electric hammer with improved construction, while ensuring the vibration reduction performance. According to the present invention, a representative electric hammer may include a hammer bit, a driving motor, a crank mechanism and a counter weight. The crank mechanism drives a striker by converting a rotating output of the driving motor to linear motion in the axial direction of the hammer bit. The counter weight is detachably mounted to the crank mechanism and serves to reduce vibration of the striker. According to the representative hammer, because the counter weight is detachably mounted to the crank mechanism, it is possible to switch between the mode in which the counter weight is mounted on the hammer body in order to reduce and alleviate vibration and the mode in which the counter weight is removed from the hammer so that the operation can be performed with the hammer having a lighter weight and slimmer appearance. Thus, utility of the electric hammer can be improved.
