Abstract: At least one electric pulse having a predetermined voltage which is higher than a switching voltage for a pnpn semiconductor device and a predetermined width is applied across the pnpn semiconductor device. The electric pulse width is set not to turn the pnpn semiconductor device on. Consequently, a predetermined amount of carriers are accumulated in the pnpn semiconductor device. In this circumstance, a trigger light is supplied to the pnpn semiconductor device to be turned on. As a result, an energy of the trigger light is largely decreased as compared to a conventional method.

Abstract: 2.1 The object of the invention is to improve the method so that comparatively little technical expense is required for implementation and that little side information occurs which is susceptible to interference. …<??>2.2 The object is solved through logarithmic quantisation of the spectral value quantities and linear quantisation of the phases, and further through division of the logarithmically quantised quantities into groups and frequency-based selection of the quantities of the groups. A representative value is formed for each group through root mean square formation. The representative values, the linearly quantised phases and the scaling factors obtained from the fast Fourier transformation are supplied to a multiplexer, at whose output a data-reduced digital signal is made available. For recovery of an approximated digital audio signal, the quantities are approximately recovered from the data-reduced digital signal and converted in conjunction with the phases into real and imaginary parts. The real and imaginary parts, along with the scaling factors, are subjected to an inverse fast Fourier transformation with scaling. Overlapping windowing then takes place. …<??>2.3 A preferred field of application for the method according to the invention is digital video recorders with a video track and sound track, and also digital satellite broadcasting. …<??>3. Block diagrams of the device for data reduction and the device for approximated data recovery are shown in the drawing. …<IMAGE>…

Abstract: A mask for X-ray lithography is produced by initially forming a thin layer of polycrystalline silicon on a silicon oxide containing substrate. A portion of the substrate at the periphery of the major surface opposite the silicon layer is masked. The exposed portion of the substrate is removed by an etchant that is selective for silicon oxide containing composition relative to silicon, e.g. aqueous HF. The resulting membrane of silicon on a peripheral region of silicon oxide containing composition is in tensile stress as required for lithography, but is robust. Metal, X-ray absorbing patterns are formed on the silicon by standard lithographic procedures.

IPC: H01L21/285
Filed: 1990-10-25
Abstract: This invention concerns a non-alloyed ohmic contact to III-V semiconductor material in a III-V semiconductor device on a Si base (11). The ohmic contact includes at least one set of layers (14,15; 16,17; 18,19) comprising a delta-doped monolayer (15,17,19) and a thin layer of undoped III-V semiconductor material (14,16,18) which is 2.5nm or less in thickness, said at least one set of layers being upon a doped III-V semiconductor layer (13). An epitaxial layer of metal (20) upon an uppermost of the layers of the said set of layers completes the ohmic contact, said metal being capable of wetting the surface of the III-V semiconductor material and of being epitaxially grown on the said III-V semiconductor material. At least the said at least one set of layers and the metal layer are deposited by molecular beam epitaxy, thus avoiding formation of oxides and growing the metal epitaxially so that the metal layer is crystalline at least near the interface between the metal and the semiconductor material. The epitaxial deposition of the metal is conducted at a relatively low temperature of the semiconductor material. In an illustrative embodiment the metal is Al and is epitaxially deposited at a temperature within the range 10°C to 100°C, preferably 20°C to 50°C, with 25°C being most preferable. The resultant contacts exhibit specific resistance which is lower and current passing capabilities which are higher than those of prior art non-alloyed ohmic contacts. However, the most noteworthy advantage of using Al in an integrated opto-electronic circuit comprising a III-V semiconductor device on a Si base, is the avoidance of "purple plague". The "purple plague" may arise when gold-based contacts in III-V semiconductor devices and Al-based contacts in Si-devices, all in a single integrated circuit, come in contact, especially at higher temperatures (e.g.300°C).

Abstract: A method for fabricating optical components in the cladding of an optical fiber bus by the utilization of a laser. An excimer laser (601) fabricates either an optical coupler opening or an optical mode scrambler (613) by ablatively removing the cladding (506) from the optical core of an optical fiber bus (505) without damaging the optical core. Either coupler housing or a mode scrambler housing is attached to the optical fiber bus where the coupler or mode scrambler is to be fabricated. The coupler housing is used to position the laser, secure and align a coupler fiber, and provide cavities for junction and cladding repair materials. The mode scrambler housing (502) serves a similar purpose.

Abstract: A supporting unit (52) for lens drive for supporting an objective lens (46) movably in vertical and horizontal directions to focus a light beam on an optical recording medium (41a) includes: a lens holder (51) for holding the objective lens (46);a mounting portion (66,66') for mounting the lens holder (51); a fixing portion (61) for fixing the supporting unit for lens drive; a pair of coupling members (62,63) disposed in parallel with each other in the vertical direction between the mounting portion (66,66') and the fixing portion (61); a pair of first hinge portions (65,65') coupling one end of each of the coupling members (62,63) to the mounting portion (66,66'); and a pair of second hinge portions (64,64';74,74') coupling the coupling members (62,63) to the fixing portion (61) to enable the coupling members (62,63) to move in the vertical direction. The mounting portion (66,66') can be divided into upper (66) and lower portions (66') so that the lens holder (51) can be held therebetween. According to the present invention, the hinge portions (65,65') for coupling the mounting portion (66,66') for mounting the lens holder (51) to the coupling members (62,63) have flexibilities in the vertical and horizontal directions and, accordingly, the number of hinge portions for moving the supporting unit for lens drive is reduced.

Abstract: A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements (12,12') arranged at regular intervals and fixed at their one ends to a base (2), the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures (10, 10'), the piezoelectric elements (12, 12') being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material and conductive material stacked alternately in layers. Since each piezoelectric element (12, 12') is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element (12, 12') and the nozzle aperture (10, 10') is discharged to the outside as an ink drop. Because the driving voltage required for forming an ink drop is as low, it is possible to simplify a driving circuit, and because of cutting a piezoelectric plate, it is possible to form small-sized piezoelectric elements with the same accuracy as in a process of producing a semiconductor.
