Patent EP-0268887-A2 (EP)
Inventor: YONEDA TAKAO
IPC: G05B19/23
Filed: 1987-11-04
Abstract: In a numerical control feed device, an objective velocity signal is produced from the difference between command pulses from a numerical controller, which indicative of an objective feed amount and an objective feed rate for a slide of a machine tool, and a feedback feed amount from a pulse generator driven by a servomotor. A subtraction circuit calculates a difference signal based on the objective velocity signal and a feedback velocity signal from a tachogenerator also driven by the servomotor and applies the difference signal to a drive amplifier for driving the servomotor. A frequency-voltage converter generates a feedforward velocity signal depending on the frequency of the command pulses. A gain adjustable amplifier amplifies the feedforward velocity signal at the amplifying ratio designated by the numerical controller and outputs the amplified feedforward velocity signal to the subtraction circuit for addition. The numerical controller determines the amplifying ratio based on various parameters such as the mechanical characteristic of the machine tool, the shape of a workpiece to be machined, an objective feed rate used in an instantaneous machining operation, and so forth.

Abstract: According to this invention, particles are obtained by hydrolysis of a metal alkoxide with a dispersion of water-alcohol system having dispersed therein a metal oxide or metal hydroxide as a seed, while keeping said dispersion under alkaline conditions, and allowing a decomposition product of said metal alkoxide to attach onto said seed, thereby effecting particle growth the seed. The particle obtained are preferably used in particular as spacer particles for display device since they are sharp in particle size distribution thereof and maintain a good state of dispersion. In accordance with the invention, moreover, there can be obtained black particles by subjecting the particles obtained in the manner described above to heat treatment at a temperature above 250 o C. When the black particles obtained are used as spacer particles for display devices, images having excellent contrast can be obtained. Still further, the particles obtained in the manner described above are coated on the surface thereof with a synthetic resin, and the resin coated particles are used as spacer particles for display devices, whereupon the particles do not move in the display devices where they are used.

Abstract: The ultrasonic wire bonding method for bonding the conductor of a sheathed wire to the terminal of an electronic part comprises the steps of forming a first rough-finished surface on either a portion of the sheath of the sheathed wire or the end of a bonding tip which is to be in contact with the sheath and to impart an ultrasonic vibration to sheath, while forming a second rough-finished surface on either another portion of the sheath of the sheathed wire or the face of the terminal of the electronic part to which the conductor of the sheathed wire is to be bonded; and placing the sheathed wire between the bonding tip and the terminal and imparting an ultrasonic vibration to the sheathed wire while lightly forcing the bonding tip to the terminal. The sheathed wire has the sheath thereof scraped without slip­ping and thus the conductor thereof naked, and this conductor is thereafter or simultaneously bonded to the terminal positively, which can improve the efficiency of wire bonding.

Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Rückgewinnen von Lösemittelgasens bei der Trockung von mit einem organischen Lösemittel behandelter Ware mit Hilfe eines Luftstroms in einer Chemischreinigungsmaschine oder dergleichen. In einer solchen Maschine wird die Ware durch einen in einem geschlossenen Leitungskreislauf umlaufenden Luftstrom, der vor dem Kontakt mit der Ware erwärmt und danach zwecks Kondensation der aufgenommenen Lösemittelgase wieder abgekühlt wird, getrocknet. In einer zweiten Phase der Rückgewinnung, der sogenannten Reduktionsphase, wird die Ware dann durch Abschalten der Erwärmung gekühlt. Zur Rückgewinnung der restlichen, nach der Kühlung noch in der Luft verbliebenen Lösemittelgase wird der Luftstrom dann anschließend über eine Adsorptionseinrichtung geleitet. Die Erfindung besteht darin, daß während der Kühlung nur ein Teil der gekühlten Luft der Adsorption zugeführt und danach wieder in den über die Ware zirkulierenden Luftkreislauf zurückgeführt wird. Dies wird dadurch erreicht, daß in einem zu dem Kreislauf parallelen, einer Adsorptionseinrichtung (11) aufweisenden Leitungszweig ein weiterer Ventilator (10) vorgesehen ist, und die Saugzug führende, mit dem Eingang der Adsorptionseinrichtung (11) verbundene Leitung (9) an den Leitungskreislauf - in Umlaufrichtung gesehen - nach dem Luftkühler (5) im Bereich der Einführung des Luftstroms in den Behandlungsbehälter (1) anschließbar ist.

Abstract: In order, in a vehicle heater with a liquid-cooled internal combustion engine and a heat accumulator, to permit the quantity of hot cooling agent stored in the heat accumulator to be fed independently of the passenger compartment heating, it is proposed to connect the heat accumulator in a bypass of the passenger compartment heat exchanger. In order to achieve a rapid recharging of the heat accumulator when the internal combustion engine is at operating heat, the heat accumulator is connected into the heat circuit in such a way that during recharging its flow direction runs oppositely to the flow direction during discharging. Thus, the required amount of heat is always available for the passenger compartment heating to an unrestricted degree. <IMAGE>
