In a laser radar, a first scanning member scans a laser beam in a virtual plane passing through an axis. A control means controls displacements of the first scanning member to change a scan beam angle in the plane. A second scanning member deflects the scanned laser beam and again scans the deflected laser beam toward an external space. A light collecting means collects reflected light. A driving means rotates both the second scanning member and the light collecting means about the axis. The second scanning member has a deflecting surface to deflect the laser beam. The deflecting surface is formed around the axis and has a plurality of reflecting surfaces coaxially arranged centering on the axis. The reflecting surfaces have different inclinations with respect to a horizontal plane perpendicular to the axis.

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.

An exhaust turbocharger with a variable-nozzle mechanism with fail-safe feature included is provided with which, even if wear of the drive ring supporting part where the supporting elements are in reciprocating sliding or rolling contact with each other under high temperature without lubrication increases, the drive ring can be supported on the nozzle mount on the second supporting part, which enables the drive ring to be always supported rightly on the nozzle mount, and to prevent the occurrence of eccentric rotation or dropping out of the drive ring due to excessive wear of the drive ring supporting part or the occurrence of reduction in engine performance due to malfunctions of the variable-nozzle mechanism such as the error in the relation between the output of the actuator and the nozzle vane opening or the occurrence of breakage of the variable-nozzle mechanism as has been experienced in prior arts.

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.

Semiconductor fabrication methods to forma of via contacts in DSL (dual stress liner) semiconductor devices are provided, in which improved etching process flows are implemented to enable etching of via contact openings through overlapped and non-overlapped regions of the dual stress liner structure to expose underlying salicided contacts and other device contacts, while mitigating or eliminating defect mechanisms such as over etching of contact regions underlying non-overlapped regions of the DSL.

An insulated glass (IG) internal blind assembly including a clutch for providing directional friction when raising and lowering the blind. The clutch is directionally activated, the gravitational pull of the blinds or lowering the blinds activates the clutch causing it to lock and add friction to the system. The clutch may be placed essentially anywhere along the cord path where the path changes direction. 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.

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.
