Title: Method of the distribution of a dopant in a doped semiconductor body
IPC: H01L21/331
Filed: 1975-01-09
Abstract: 1488943 Semi-conductor devices COMMISSARIAT A L'ENERGIE ATOMIQUE 9 Jan 1975 [10 Jan 1974] 924/75 Heading H1K The doping profile of a semi-conductor body is modified by bombarding it at elevated temperature with particles of such composition, energy and dose that a peak is produced in the doping profile by migration of the initial dopants into a volume adjacent the region in which the particles come to rest. The particles may be charged, e.g. protons or ions (in the latter case the process may be combined with conventional ion implantation), or uncharged, e.g. molecular or atoms such as rare gases, Si, C or Ga. The initial dopant distribution may be uniform, having been grown into the semiconductor, or non-uniform, e.g. as produced by ion implantation or diffusion. Curve II of Fig. 4 illustrates the final form of an initially diffused boron profile in Si after bombardment with protons at elevated temperature. As and P are mentioned as other dopants which may be redistributed in this way. Several irradiations using different particle energies may be used to obtain a broader dopant peak. Particular applications include the formation of a buried high-conductivity collector portion in a bipolar transistor (Figs. 5, 6, not shown), of a recombination - preventing high - conductivity zone adjacent the semi-conductor/substrate interface of a silicon-on-insulator lateral transistor or P<SP>+</SP>NN<SP>+</SP> diode (Fig. 7, not shown) and of a depletion mode MOSFET having a very steep dopant gradient in the channel region (Fig. 8, not shown).

Title: Electronic timepiece
IPC: G04C3/00
Filed: 1982-03-25
Abstract: 1474002 Electronic watches DAINI SEIKOSHA KK 21 Feb 1975 [7 March 1974] 7441/75 Heading G3T [Also in Division H1] In an electronic timepiece having a display (1), Fig. 1 (not shown) with several portions e.g. for the date, day, hours, minutes and seconds, a stem 17 is mounted on a base-plate 15 for axial and rotary movement and controls at least three switches to correct the display. Inner and outer positions of the stem are defined by a flange 27b of a spring 27 engaging the stem on respective sides of collar 17b. Square portion 17a of the stem carries a switch member 22, and a spring 24 biases this member and thus the stem to a central position in rotation. With the stem in its inner position as shown, all the switches are open and the watch runs normally. When the stem is pulled out, its end 17d allows a contact spring 18 to touch a contact pin 19, these parts forming an enabling switch 13 so that, by logic circuitry Fig. 2 (not shown), further switches 10-12 are rendered effective. The switch 10 is a function selector switch formed by a contact 25 and a lug 22a on member 22, so that if the stem 17 is now rotated clockwise this switch is closed and switch 11, which is a correcting switch, is connected via the logic to the date display (2) which becomes illuminated to show that it is available for correction. The switch 11 is formed by a second contact 26 and lug 22b and rotation of the stem anti-clockwise thus causes 1Hz pulses to pass to the date display. Subsequent clockwise rotations of the stem connect the switch 11 successively to the day, hours and minutes display portions (3-5), the selected portion being illuminated. Depression of the stem, while still in its outer position, against a spring 23 and contact spring 18, will cause the latter to touch a contact 20, thus closing switch 12 and setting the seconds counter (204) and display (6) to zero. The display is of liquid crystal type, illuminated by a lamp (9) when a switch 14 is closed. This switch is formed by the spring 18 and a further fixed contact 21 and is closed by depressing the stem in its inner position. The switch 12 is also thus closed but is ineffective since switch 13 is open.

Title: Household appliance having a fan-cooled electric driving motor
Inventor: BAUER ALFRED
IPC: H02K9/04
Filed: 1997-04-17
Abstract: Household appliances having an electric collector driving motor (2) the winding of which is cooled by a fan (5) driven by the same driving motor (2) are known. According to the invention, the fan (5) is driven by its own electric, d.c. motor (4), having also a collector. The fan motor (4) and the driving motor (2) are electrically interconnected in such a way that with an increasing load moment at the driving motor (4) the armature current of the fan motor (4) also increases. On the contrary of known household appliances, the driving motor (2) is thus more strongly cooled when its heat emission increases and is less strongly cooled when its heat emission abates.

Inventor: CUDINI IVANO G
IPC: B21D53/88
Filed: 1985-11-15
Abstract: A box section frame member is formed by deforming the opposing sides of a tubular blank inwardly to provide curved concave portions (19b, 21b, 26b, 27b, 32b, 33b,) in areas corresponding to opposing flat surfaces of the product. The deformed blank is expanded, under internally applied fluid pressure within a sectioned die, sections (18b, 24b, 31b) becoming trapezoidal, square and rectangular respectively. The concave portions of the deformed blank allow the blank to be confined within the die without pinching of the blank occurring upon closure of the die; permit substantially uniform expansion of the blank within the die; and allow the blank and final product to be formed with a smooth, continuous cross-section. This avoids stress concentration in the deformed blank and final product which can impair the mechanical strength of the product. To avoid weakening, cracking or yielding through excessive circumferential expansion the final product should have a circumference no more than 5% larger than the circumference of the tubular blank. The tubular blank may be bent into complex configurations, preferably before deformation.

Title: Multiple branch peptide constructions for use against hiv
Inventor: SABATIER JEAN MARC
IPC: C07K14/16
Filed: 1996-03-13
Abstract: Multiple branch peptide constructions formed from peptides derived from the V3 loop of gp120 protein of HIV-1, and including the consensus sequence GPGR preceded by 0 to 4 amino acids and succeeded by 2 to 4 amino acids, preferably not including I in the 3 amino acids immediately preceding GPGR and most preferably GPGRAF, show increased receptor affinity and prevent cell-to-cell fusion. They have a direct virostatic effect. Because they present the same peptide sequence several times, these MBPCs are able to neutralize in vitro the different steps of virus envelope/cell membrane fusion, and infected cell membrane/uninfected cell membrane fusion of several strains of HIV-1 and HIV-2. Notably, they are effective in blockading both CD4 receptors on lymphocytes and macrophages and GalCer receptors on colon epithelial cells. These results open a potential use in treatment of HIV-1 and HIV-2 infection.
