Abstract: A comparator (1) compares with a threshold (Sn) each value (POn) of a sequence of first values each representing the intensity of one pixel of the image to be processed, which intensity is able to vary continuously, and delivers at output a second value (PRn) relating to the same image pixel as the said first value, and representing the intensity, able only to vary discretely, of the processed image. A circuit (3) is provided for calculating the value of the threshold in response to second values (PRn-1, PRn-2,... PRn-q) relating to a plurality of previously processed pixels, and a circuit (4, 5) for randomly perturbing the calculated value of the said threshold.

Abstract: A cool wig-like hat produced by implanting artificial hair in an artificial head skin. The artificial hair consists of carbon fibers or thin thread-like products each of which is composed of a plurality of knitted carbon fibers, while the artificial head skin consists of a central net portion (1) obtained by forming a net with carbon fibers or thin thread-like products each of which is composed of a plurality of knitted carbon fibers, and a circumferential web-like portion (2) provided on the outer circumferential part of the central net portion and having a plurality of minute holes. The carbon fibers have a very high heat conductivity and excellent heat radiation characteristics, so that they can prevent the head from becoming stuffy and from perspiring, i.e., they can prevent the occurrence of the phenomena encountered, especially, when a conventional wig is worn. Since the carbon fibers have a high chemical resistance, perfumed ointment and a dyeing agent can be applied freely to this cool wig-like hat. The hat according to the present invention is produced by bringing the artificial hair (3) into contact with an artificial head skin (6) through a sieve member (4) and a boring frame (5), and fixing the hair thereto.

On procède à l'alcoylation de l'oligomère de la gamme lubrifiante à l'aide d'un catalyseur d'alcoylation acide tel qu'un catalyseur solide à pores ouverts, par exemple de l'oxyde d'aluminum fluoré. Les compositions lubrifiantes améliorées de l'invention comprennent une composition d'oligomère lubrifiant liquide d'indice de viscosité élevé, contenant des hydrocarbures C30-C1300 comportant au moins une ramification d'alcoyle inférieur contenant entre 12 et 40 atomes de carbone. Dans un mode de réalisation préféré, la nouvelle composition lubrifiante alcoylée a un rapport de ramification entre le méthyle et le méthylène inférieur à 0,19, ainsi qu'un point d'écoulement inférieur à -15°C.

Abstract: Procédé et dispositif pour contrôler le transfert de chaleur et par conséquent l'efficacité d'un condensateur. En bloquant un tube de condensateur, on provoque la formation d'une colonne d'eau qui prend la température de la vapeur TS. On débloque alors le tube de condensateur et l'on peut mesurer le débit sur la base du temps d'écoulement de l'eau. Lorsque l'on connaît la température d'entrée T1 et la température de sortie T2 de l'eau, mesurées sur le même tube de condensateur, on peut déterminer avec précision le transfert de chaleur à travers ce tube de condensateur, ce qui permet de faire fonctionner en conséquence un dispositif de purification avec des boules de caoutchouc cellulaire, par exemple. On peut ainsi utiliser intégralement le potentiel d'efficacité du condensateur.

IPC: B25J9/18
Filed: 1990-09-17
Abstract: This invention relates to a sliding mode control method which can improve a property of a control system to follow up an instruction at the time of change of the operation conditions of a machine and can prevent vibration of the machine which is likely to occur due to the action of spring elements of the machine when the operating conditions change. A processor of a servo circuit calculates a position error (c) and a speed error (ε) on the basis of an instructed position (er) and an actual position (θ), estimates a twist quantity ( E n) and a twist speed ( E n) by observer processing and calculates a switch plane (s) (102). The processor calculates each of the first to fourth terms of the switch quantity (T1) in accordance with the positive or negative and position error of the switch plane (s), the second order differentiation of the instructed position and one corresponding positive or negative of twist quantity and twist speed (103 - 129) and then calculates a torque instruction (T) sufficient to converge the switch plane to zero on the basis of the switch quantity obtained by adding these four terms (130, 131). Even when non-linear parameters associated with the spring elements of the machine change, the servo system follows up the change in an excellent way and prevents the vibration of the machine.

Abstract: A power saving method and apparatus in a time division multiplexed system (10) capable of providing a synchronous full duplex communication between a telephone network (12) and a plurality of remote communication units (18). A communication resource controller (14) provides system synchronization, by periodically trnsmitting synchronization messages through one or more remote sites (11). The communication units (18) attempt to acquire synchronization during a synchronization acquisition interval. If synchronization is acquired, the communication units (18) enter a synchronous battery saving mode (515). In the synchronous battery saving mode (515), the communication units (18) can detect a call request either to their own address or to the address of another communication unit. If no call request is detected, the communication units (18) reduce power consumption for a synchronous power saving time interval, and thereafter merely verify synchronization. However, if synchronization is not acquired, the communication units enter an asynchronous power saving mode (525), wherein they reduce power consumption for an asynchronous power saving interval. The communication units (18) may enter the asynchronous battery saving mode (505), if a call request to another communication unit is detected. The asynchronous power saving interval is substantially longer than synchronous power saving interval.

Abstract: The machine, especially a honing machine, has several working stations (W1 to Wn-2) in which workpieces can be worked or honed simultaneously. By transfer in timed sequence, each workpiece can pass in succession through all stations (W1 to Wn-2) so that it is worked gradually first of all to intermediate sizes and in the final working station to finished size. So that the working operations can be corrected, for example to re-adjust the tools for wear compensation, a common measuring station (Wn-1) is provided for all working stations (W1 to Wn-2), into which measuring station (Wn-1) the workpieces, after interruption of a work cycle, can be moved in succession in a measuring cycle. Attached to the measuring station (Wn-1) is a measuring and control device (19) which determines the deviations of the workpiece size from the desired size and analyses them for the subsequent control of the individual working stations (W1 to Wn-2), in particular for the re-adjustment of the individual tools. <IMAGE>

Abstract: The present invention relates to a method for growing diamond on a diamond substrate by chemical vapor deposition. The inventive method comprises alternatingly contacting at elevated temperature said diamond substrate with a gas having the formula C n X m  and then with a gas having the formula C l Z p . X and Z each form single bonds with carbon. X and Z also are reactable to form ZX or a derivative thereof. The Z-X bond is stronger than the C-X bond and also is stronger than the C-Z bond. In the formulas, n, m, l, and p are integers. If C n X m  and C l Z p  do not react in the gas phase, then a gas mixture of them can be used to grow diamond instead of the alternating exposure of one and then the other.
