Abstract: A low power magnetic bubble memory for use in, for example, telephone repertory dialer operation is achieved with existing bubble functional elements. An electrical conductor pattern is adapted to input, simultaneously, bubble patterns representative of decimal digit information as well as the control information for properly queuing and storing that information. An adaptation of the familiar major-minor bubble organization is employed. The dialer is designed to operate on sufficiently low power to be powered entirely from a telephone central office.

Abstract: Ferroelectric crystals which are also ferroelastic, such as gadolinium molybdate, can support stable internal ferroelectric polarization domains. These domains are expanded and moved in the ferroelectric crystal by means of a sequence of voltages applied to electrodes on the surface of the crystal. Thereby, optically readable, shift register logic functions are achieved using (for readout) an incident optical beam with respect to which the ferroelectric domains are birefringent.

Abstract: A pulsed second harmonic output is obtained from a continuously pumped laser at repetition rates in the 1-10 MHz range. This is accomplished by electrically pulsing an intracavity nonlinear element to establish momentarily the phase-matched condition required for second harmonic generation. The generated harmonic is a high-amplitude optical pulse which is coupled out of the cavity via a harmonic-transparent mirror.

Abstract: Members of a particular class of magnetic garnet compositions show characteristics useful for incorporation in magnetic memory devices which depend for their operation on the positioning of single wall domains (''''bubbles''''). Such compositions ordinarily in the form of a supported layer are noteworthy for high bubble mobility and small temperature dependence of magnetic properties affecting operation. These compositions include silicon and/or germanium as a partial replacement for iron.

Abstract: Incoherent light sources depending on phosphors which may simultaneously emit at more than one wavelength are provided with multiple dielectric coatings to suppress a portion of the emission and thereby enhance the remainder. The use of such coatings with frequency up-converting phosphors as well as downconverting phosphors is described.
