Abstract: Disclosed are a method for generating a quantum state preparation circuit, a quantum state preparation method, and a quantum device. The method for generating the quantum state preparation circuit includes: configuring, based on circuit preparation parameters of the quantum state preparation circuit, an input register for the quantum state preparation circuit and determining the number of auxiliary quantum bits (302); configuring a copy register and a target register for the quantum state preparation circuit according to the number of the auxiliary quantum bits (304); obtaining a diagonal unitary matrix quantum circuit by performing circuit construction through the input register, the copy register and the target register according to a quantum bit copy mode, the quantum bit copy mode being obtained based on a grid restriction condition (306); combining the diagonal unitary matrix quantum circuit and a single bit quantum gate to obtain a uniformly controlled gate circuit corresponding to the diagonal unitary matrix quantum circuit (308); and generating the quantum state preparation circuit based on the at least one uniformly controlled gate circuit (310). Influence of de-coherence can be reduced by adopting the method.

Abstract: A single level masking process for producing microelectronic structures, such as magnetic bubble domain devices, which require very fine line widths. This is a subtractive dry process using a very thin, additively plated mask (38) in order to obtain optimum lithographic resolution. Use of the very thin plated mask eliminates the need for a thick resist layer which would adversely affect resolution, In one example, a structure of a double layer metallurgy (28, 30) comprising a conductor layer (such as Au) and an overlying magnetically soft layer (such as NiFe) is subtractively patterned using a thin Ti (or Cr) mask (32). The Ti mask is subtractively patterned using a NiFe mask (38) which is itself additively patterned by electroplating through a thin resist layer (36). The double layer NiFe/Au structure (30, 28) is patterned to provide devices having high aspect ratio, good pattern acuity, and uniform thicknesses, where the minimum feature is 1 νm or less.

IPC: B65B3/14
Filed: 1980-09-10
Abstract: Les systemes de remplissage en question utilisent une pression pneumatique maintenue dans des limites de tolerance tres rapprochees pour imposer une force de distribution constante du materiau. Dans un mode de realisation, on utilise un systeme de reservoir tampon dans lequel le produit a distribuer est transfere d'un reservoir d'alimentation (11) au reservoir tampon (12) ou la pression desiree est etablie par l'intermediaire d'une tete pneumatique introduite au-dessus du niveau du produit. Le niveau du produit dans le reservoir tampon (12) peut fluctuer dans une zone relativement etroite de profondeur de maniere a annuler l'effet des changements de la pression par gravite de la tete pneumatique. Le systeme ferme est pressurise et rempli a nouveau en forcant le produit d'arrivee dans le reservoir (12) sous une pression superieure a celle qui regne dans le reservoir tampon (12). L'air du reservoir (12) qui est deplace en introduisant le nouveau produit est automatiquement mis a l'atmosphere a l'aide d'un systeme de commande de precision (45). Le systeme d'equilibrage de la pression comprend soit un piston soit un dispositif de commande d'equilibrage d'un diaphragme (81) qui commande une vanne pneumatique a trois voies (72) pour charger ou mettre a l'event le reservoir de distribution (58). La pression de reglage desiree du produit est appliquee sur un cote de l'organe d'equilibrage (80) et la pression reelle du produit est appliquee de l'autre cote. Au fur et a mesure que le niveau baisse dans le reservoir (58), la pression de la colonne baisse, et ceci est detecte au fond du reservoir. L'organe d'equilibrage (80) favorise le cote ayant la plus petite pression provoquant l'ouverture de la vanne a trois voies (72) et la charge pneumatique du reservoir (58) jusqu'a ce que la pression predeterminee et la pression reelle du produit soient egales. Si la pression reelle du produit devient superieure a la pression predeterminee, l'organe d'equilibrage (80) actionne la vanne a trois voies (72) pour degager la pression en

Title: Fluid sequence bypass apparatus.
Inventor: OBERTH HANS G
IPC: F16N13/22
Filed: 1981-04-08
Abstract: In some piston engines a pressurized fluid which is delivered to a main receptor (16) is also delivered to a secondary receptor (18) from which it is directed to cool the pistons. During engine startup and low idle operation such cooling is unnecessary, and further, it is desirable to provide as much fluid flow as possible to the main receptor (16), which is generally the main lubricating manifold (16) of the engine. Herein, delivery of the pressurized fluid to the secondary receptor (18) is prevented until the fluid pressure in the main receptor (16) reaches an initiating value (A). The main receptor (16) thus receives added fluid flow at startup and during low idle operation, while adequate piston cooling is provided at normal operating speeds.

Abstract: A video signal recording and reproducing apparatus in which the luminance signal of a color video signal is frequency-modulated for recording and a reproduction frequency-modulated signal is frequency-demodulated to produce a reproduction video signal. A high frequency component is separated from the reproduction video signal and applied to a slice circuit (33, 42, 53) comprising nonlinear elements including, for example, diodes connected in parallel in reverse polarities, thus eliminating noise at the flat portion included in the high frequency component. The apparatus further comprises a device (35, 43, 47) for subtracting the sliced signal and the reproduced video signal one from the other in such a manner that the two signals are in phase with each other substantially at the desired ratio and in predetermined frequency band. In this way, noise contained in the edge portion of the reproduction video signal, crosstalk and moire patterns caused at the time of azimuth recording without guardband are decreased, thus improving the signal-to-noise ratio of the edge portion. If this apparatus is combined with a conventional device fr reducing noise at the flat portion, FM interleaving tec. niques and nonlinear emphasis, a high-density recording with narrow tracks and short wavelength is made possible, thereby producing a stable reproduced image with high S/N ratio having no undesired components.

Abstract: Delay circuits (21) and (22) and logic gates (23, 24, 25) provide an output which is representative of three successive like bits appearing on the compander input line. Multiplier (26) multiplies the current delta step value A by 1/16 and multiplier (27) multiplies the same by -1/64. When the output of logic gate (25) is a 1, (three like bits), AND gate (28) let the output of multiplier (26) apply to three input adder (31). The output of this adder then delivers a delta step signal Δn = Δ n-1  +     When the output of logic gate (25) is a zero, the new delta step is     since AND gate (28) does not deliver any output. Multipliers (26) and (27) are shift registers, and the division by 16 or 64 is performed by achieving a four (or six) bit right shift and dropping the right most four (or six) bits.

Abstract: Medium consistency oxygen delignification of pulp is carried out in a series of tubular reaction zones. Rapid delignification is achieved by agitating the pulp by rotating a timing screw in the first reaction zone at a speed in excess of 10 rpm, modifying the flights on the timing screw to increase the amount of agitation, or a combination of the two. Primary oxygenation is carried out in the first reaction zone while subsequent zones provide the retention time needed for the delignification reaction to go to completion. A thick stock pump is used to introduce the pulp into the first reaction zone.
