摘要： PROBLEM TO BE SOLVED: To provide a device to supply a target material having a shape of a nozzle for an EUV radiation source. SOLUTION: The nozzle (50) includes a targeted material supply line (66) having an orifice (68) in which small drops (76) of a liquid target material (64) are discharged, and the small drops have a specified dimension, speed and spacing between the small drops. The small drops are mixed with a carrier gas (74) in a mixing chamber (54) surcumscribing a target material room (66), and the mixture of the small drops and the carrier gas is put into a drift tube (56) from the mixing chamber. The small drops are discharged from the drift tube to an acceleration room (124), and there the speed of the small drops may be increased so as to control the spacing between the small drops. A vapor extractor (90) can be mounted on the acceleration room or the drift tube in order to remove the carrier gas and target material vapor by which an adverse influence on the generation of EUV radiation may be possibly exerted.

摘要： PROBLEM TO BE SOLVED: To provide a laser oscillator with a negative spherical aberration. SOLUTION: This laser oscillator (10) includes a reflective mirror (14) and an output coupler mirror (24). Two gain media (16 and 22) are disposed between the reflective and output coupler mirrors (14) and (24) and each of the mirrors (14) and (24) is pumped with energy to produce laser oscillation between the mirrors (14) and (24). Each of the gain media (16 and 22) has a focal strength during operation that is formed by thermal and mechanical stresses. This laser oscillator (10) also includes a lens system (18) disposed between the two solid- state gain media (16 and 22) and has a focal strength about equal to or greater than a product of the focal strengths of the two media (16 and 22). A polarization rotator (20) is also included in this oscillator (10) and disposed between two gain media (16 and 22). COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a channelizer for recovering many communication channels at the same time without the need for using a sub-band tuner in duplicate. SOLUTION: The channelizer (224) comprises an n-point discrete Fourier transform (DFT) circuit (208) coupled to an output data rate output (226) and a plurality of individual recovered channel outputs (210) coupled to the DFT circuit (208). Resampling circuitry (302, 306) in a resampling filter (204) converts an input data rate to an output data rate in a manner commensurate with a preselected communication channel spacing, communication channel output sample rate, and the number of communication channels. The DFT circuit may use (n-m) point overlap and the channelizer (224) may further include a polyphase filter (206) implementing n/m oversampling coupled between the resampling filter and the DFT circuit.

摘要： PROBLEM TO BE SOLVED: To provide a technique for simultaneously thinning semiconductor wafers. SOLUTION: With respect to the devices (10, 100) for simultaneously thinning the rear faces of several semiconductor wafers (W) by using a noncrystalline uniform etching process and a method by using them, the devices (10, 100) include fixing jigs (12,102) having several horizontal receptacles (14, 16, 18, 20, 104, 106, 108 and 110) for housing the semiconductor wafers (W). The loaded fixing jigs (12,102) are impregnated with etching solution (36, 146) which can remove semiconductor material layers in an isotropic manner from the rear faces of the semiconductor wafers (W). The etching solution (36, 146) is preferably heated to about 40-50°C and is constantly agitated by magnetic stirrer bars (48, 158). After a sufficient time has passed, the thinned semiconductor wafers (W) are taken out from the etching solution (36, 146). The devices (10, 100) can simultaneously thin several semiconductor wafers (W) to the final thickness of about 25 μm. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an apparatus having a monitoring unit integrated together with various active devices through relatively simple manufacture. SOLUTION: The apparatus integrates an optical energy transmitting and/or receiving function with, for example, the GaAs or InP unit of the active device or, for example, the laser of a light-emitting unit. This apparatus comprises a passivation layer (34) on the active device, an silicon photodetectors (38, 40, and 42) on the layer (34). The photodetectors (38, 40 and 42) may be formed by utilizing a standard solar cell growing process, may be formed as a mesa on the active device or the light-emitting unit. Accordingly, the semiconductor which has the integrated monitoring unit and is not relatively complicated is formed.

摘要： PROBLEM TO BE SOLVED: To provide an optical switching device that routes an optical data packet by using an all optical architecture signal detection and switching system in an optical region. SOLUTION: The packet includes header bits 16, data bits 18, and a reset bit 24. The header bits identify the switch state for routing the data packet and the specific routing information for distinct portions of the data packet. The header bits are transmitted at an optical carrier frequency different from the carrier frequency of the data bits. The reset bit resets the switch element processor to enable it to process and route the next data packet. The frequency of a particular header bit affects the index of refraction of a Bragg grating of a detector 42 and the output of the detector is provided to a switch that determines the routing path of the packet. A return command resets the diffraction grating, so that it does not affect subsequent header bits.

摘要： PROBLEM TO BE SOLVED: To provide variable bandwidth satellite communication techniques that maintain a high bandwidth efficiency and high service quality. SOLUTION: Multiple bandwidth requestors 201, a bandwidth manager 401 and a forward link from the bandwidth manager to the bandwidth requestor 410 are used to allocate bandwidth in a return link beam 210. The uplink bandwidth allocation is preferably decided based on the information to be transmitted provided by the user ADPE(automatic data processing equipment) 300 and overall system data loading. The preferred method exercised by the bandwidth manager 401 allocates bandwidth on the return link 210 to individual user terminals 200 in either a minimal rate required for the protocol being exercised 213, a committed information rate 214 required for the services being requested, or a constitutional share rate 214 that allows maximum transfer of data from the user terminal 200 to the gateway 400.

摘要： PROBLEM TO BE SOLVED: To provide a device including seat belt webbing, a parallelogramic link, a sensor lever and a sensor. SOLUTION: The seat belt webbing 12 aids protecting an occupant 14 of a vehicle 18. The parallelogramic link 220 includes a first beam 352 and a second beam 362 parallel with the first beam. The first and second beams 352 and 362 respectively bend in response to at least a portion of a load applied by the seat belt webbing 12. The sensor lever 370 is arranged between the first and second beams. The sensor lever 370 has a coupling part of the first and second beams. The coupling part deflects the sensor lever 370 when the first and second beams bend. The sensor 379 detects deflection of the sensor lever 370 and provides an output signal showing bent amounts of the first and second beams.
