Abstract: A logic circuit comprises a plurality of input terminals (IN 1 , IN 2 ,...), an output terminal (OUT), a load (L), and at least two driver circuits (D 1 , D 2 ,...). Each of the driver circuits (D 1 , D 2 ....) comprises a plurality of gates (Q l1 , Q l2 ,...) connected in series, each gate being driven by the potential at one of the input terminals (IN 1 , IN 2 ,...). In addition, first gates (Q 11 , Q 22 ,...) of the driver circuits (D 1 , D 2 ,...) connected directly to the output terminal (OUT) are driven by the potentials at different input terminals. With this arrangement at least one of the driver circuits (D 1 , D 2 ,...) operates rapidly in response to changes of input signals so as to change the potential at the output terminal (OUT). As a result, no fluctuation in operation speed is generated under any conditions of input signals, and, in addition, the operation speed is increased.

Abstract: Capacitive pressure transducer (26) having a multiplicity of signal plates (Cs, Cr, Csf, Crf) disposed on a first quartz disc (88). Opposing the signal plates (Cs, Cr, Csf, Crf) across a gap formed by an annular frit (92) is a common plate (94) disposed on a second quartz disc (86). The signal plates (Cs, Cr, Csf, Crf) and common plate (94) form capacitors which are operable to modulate alternating excitation signals applied to the signal plates. The capacitances vary the modulation during deflections of the discs (86,88) as a result of pressure changes and the common plate (94) algebraically sums the modulated excitation signals into a single output from the transducer (26).

Abstract: A permanent color photographic picture obtained by forming a latent image on a base plate durable against high- temperature baking utilizing the art of light-sensitive resin, forming an image according to dry development using a toner containing an inorganic pigment, and baking at high temperature; and a process for obtaining the picture. This process involves an easier baking step than that in conventional wet process development, and is extremely advantageous for producing permanent color photographic picture. A very excellent image quality can be attained by subjecting the light-sensitive element to an image portion-swelling step prior to the development step, and color images can be obtained, if desired, by providing the baking step merely once in the last stage of the whole processing. In this case, sufficiently good color reproduction can be attained by selecting a proper combination of pigments. The resulting permanent image is absolutely different from the obtained by conventional printing art in that it has good resolution and gradation as well as good color reproduction.

Abstract: n optical storage system employing a laser beam which is directed and focused onto an optical disk for reading and/or writing data in a track of the disk. Proper focusing is maintained using focusing control circuitry which produces a focus error signal that is applied to a focus motor. This focusing control circuitry is able to return the objective lens assembly to its in-focus position so long as the objective lens assembly remains within a predetermined capture range. In the event that the objective lens assembly is outside of this capture range, a waveform generator is enabled which produces a correction signal that causes the focus motor to move the objective lens assembly back within the capture range with a velocity and for a time period sufficient to permit the focusing control circuitry to regain control and return the objective lens assembly to its in-focus position.

Abstract: A method of providing a copper metallization on a dielectric or semioconductive body, and a dielectric or semiconductive body having a metallization consisting essentially of copper. According to the method, a mixture of copper oxide powder and 0 to 15 weight percent reduction-resistant glass frit is dispersed in an organic vehicle and a solventto produce a paste. The paste is applied to the body to provide a coating thereon. The coating is dried to remove the solvent, and then the coated body is fired in an oxidizing atmosphere at a temperature below the melting temperature of the glass frit to remove the organic vehicle. Finally, the coated body is fired a second time in an atmosphere which is reducing to the copper oxide but substantially nonreducing to the glass frit. The second firing is at a temperature from 700 to 1050°C for from 120 to 5 minutes to convertthe copper oxide to copper metal. The metallized body may comprise a reduction-resistant dielectric body and a metallization consisting essentially of copper, with no glass frit.

Abstract: A current driven flyback power supply has a transistor current switch which periodically couples a primary current through the primary winding of a power transformer which is connected between a source of DC and the collector of the current switch. A current transformer has a first winding coupled between the primary winding and the collector of the current switch, and a second winding which develops a drive current proportional to the primary current. The drive current is coupled to the base of the current switch and increases proportionally with the increasing amplitude of the primary current. An electrical switch shorts the drive current to ground to turn off the current switch so that stored energy in the power transformer is coupled out through its secondary winding to an output rectifier circuit which develops the output DC voltage. After the stored energy has been completely coupled out through the secondary winding, a first current pulse is developed to turn on the current switch to initiate the primary current. During high output power loading conditions, a second current pulse is developed at a selected point in time after the current switch turns off and prior to the stored energy being completely coupled out through the secondary winding. The second current pulse turns on the current switch whereby the initial primary current is boosted in amplitude by the residual stored energy in the power transformer.
