Abstract: Machine used for folding, profiling and cutting metal sheets includes a fixed support structure (1) holding a lower presser element (3), on which the sheet (4) rests, and an associated upper mobile presser element (5). Together, the presser elements (3, 5) keep the sheet (4) pressed in a proper horizontal plane. The machine further includes a mobile structure (7) having a C-shaped cross section which defines a channel (2) of longitudinal orientation. This C-shaped structure holds a pair of holding blades (8-9) which perform the folding of the sheet (4) when the same C-shaped structure is raised and lowered or made to advance or withdraw with respect to the sheet (4). In the interior of the channel (2) at least one removable tool holding group (10-11) is situated. This permits repositioning of the tool holding group along the longitudinal course of the channel (2).

Abstract: In a method for producing a channel region layer in a SiC-layer for producing a voltage controlled semiconductor device n-type dopants and p-type dopants are implanted into a near-surface layer of the SiC layer. The p-type dopants implanted have a higher diffusion rate in SiC than the n-type dopants implanted. The SiC-layer is then heated at such a temperature that p-type dopants implanted diffuse from the near-surface layer into the surrounding regions of the SiC-layer being lightly n-doped to such a degree that a channel region layer in which p-type dopants dominates is created.

Abstract: A process of forming ball bumps for electrical connection to an integrated circuit, the process comprising the steps of: applying a vibration at a small amplitude to a vessel containing small balls of an electroconductive material to cause the small balls to jump up above the vessel; holding and arranging the small balls on an arrangement baseplate by attracting the jumping up small balls to attraction openings provided in the arrangement baseplate in positions corresponding to positions of at least one set of the electrode pads of one semiconductor chip; removing excess small balls adhered either to the arrangement baseplate or to the small balls attracted to the openings; and simultaneously bonding the small balls held and arranged on the arrangement baseplate to bonding spots arranged in positions corresponding to said positions of said at least one set of the electrode pads.

Abstract: The spectral energy characteristic of a discharge lamp is controlled by changing the density of the fill substance. The spectral characteristic can be shifted while substantially maintaining its shape by changing the density of the fill. A sulfur or selenium containing discharge lamp which is operated at a pressure of at least about 1 atmosphere contains a low ionization potential substance in the fill. Characteristics which are improved are one or more of spatial color uniformity, extinguishing characteristics, and bulb starting reliability. Particular substances which are added to the fill are alkalai metal containing substances, III B metal containing substances, and alkaline earth metal containing substances. When light is reflected back into the bulb, the light which is re-emitted is stronger in the higher wavelengths.

Abstract: An electronic device includes a substrate, a chip attached thereon, and a molded body formed on the substrate for sealing the chip on the substrate. The electronic device further includes bumps formed at the underside of the substrate for connection to electrodes of a printed board. In an electronic device mounting method, a first correlation between a magnitude of warp of the electronic device and a heating temperature of the electronic device is derived. The warp is caused by a difference in thermal expansion coefficient between the molded body and the substrate. In the method, a second correlation between the magnitude of warp of the electronic device and a failure rate of coupling between the bumps and the electrodes is further derived. The method further derives, based on the first and second correlations, a heating temperature which causes no coupling failure between the bumps and the electrodes.

Abstract: Porous cellulose matrices with a defined particle size and a significantly higher porosity (i.e. pore volume) than conventional formulations, such as pellet formulations containing cellulose and binders are prepared. The cellulose is mechanically treated with low adhesion to the process equipment during a controlled gradual addition of an aqueous based fluid, optionally containing a surface-active ingredient, into regular particles, which are finally dried to obtain dry porous cellulose matrices. The so obtained matrices can be used as carriers for bioactive substances in multiple-unit preparations or tablets.

Abstract: A film-chamber cover of an advanced photo system (APS) camera is for indicating whether a film cassette is loaded within a film chamber of the APS camera or not. The film-chamber cover includes: a bottom cover furnished with a viewing window, an upper cover furnished with a shaft hole, a moving shaft slidably connected with the shaft hole between the upper and bottom covers, and a swing plate formed with characteristic symbols thereon. The swing plate is pivoted to the bottom cover and is driven by a restoring member such that when the film chamber is not loaded with a film cassette, the swing plate can be restored to a position where a symbol indicating emptiness of the chamber aligns the window of the bottom cover.

Abstract: A three-dimensional resolution chart is used to adjust the position of a solid-state image detector 4 in a given image-forming optical system. A plurality of blocks 10a are provided on an upper surface of a resolution chart 10. Each block 10a has an adjusting pattern A-D depicted on a slant surface thereof. An image of each adjusting pattern A-D is formed-on the solid-state image detector 4 through a master lens 2. The contrast integration value F is calculated based on the image of the adjusting pattern at each of a plurality of designated areas hj (j=1 - - - n) on the slant surface of each block 10a provided on the resolution chart 10, to find out a specific position on each block where the contrast integration value F becomes maximum, thereby identifying the specific position as focus point of the master lens 2. The back focus of the solid-state image detector 4 is calculated based on thus obtained focus point. An optimum gradient (.alpha., .beta.

Abstract: In a pantograph type keyboard switch, a leaf spring projects from a linkage member and slidably engages the underside of a keytop and the resulting reaction force is used to remove play between the keytop and the linkage member. Further, a frictional slope is formed in each slide groove in the underside of the keytop so that frictional force increases as the keytop approaches the top dead point position.

Abstract: Information is divided into first blocks each having m bits, and n bit or bits in each of S different states are added to a head of each of the first blocks to change the first block into S second blocks each having m+n bits, where m and n denote predetermined natural numbers and S denotes a predetermined natural number equal to or smaller than 2.sup.n. Each of the S second blocks is pre-coded into S pre-coded information blocks respectively. One of the S pre-coded information blocks is selected as a modulation-resultant information signal in response to error signals related to the S pre-coded information blocks respectively. The modulation-resultant information signal has q different notch frequencies. The S pre-coded information blocks are converted into S amplitude signals representing amplitude values respectively. A set of q first waveform signals and a set of q second waveform signals are generated. The q first waveform signals represent waveforms related to the q notch frequencies respectively.
