Abstract: Abstract Characteristics of a pulse sequence, such as frequency, are controlled in a simple circuit without requirement for specific storage components.   The cumulative effect of a sequence of control signals is maintained by providing a phase shift between a pair of waveforms.  The phase shift between the waveforms is used to provide a number of control pulses to the circuit for varying the desired characteristic.  In a particular embodiment, control signals are externally provided for varying the phase shift between two waveforms.  In response to the phase variation, a number of control signals are provided for adding or deleting pulses to a pulse stream.  The use of feedback control loops results in repeated addition and/or deletion of pulses to or from the pulse stream,  thereby varying the output frequency in accordance with a one time input of the external control signals.          Serial or parallel control signals may be provided, and ripple counters (or a combination of ripple and presettable counters) may be used for the frequency control function.

Abstract: LASER LIGHT SOURCE DEVICE              ABSTRACT OF THE DISCLOSURE     The present invention discloses a laser light source device having a laser and an external resonator, wherein a Faraday rotator is provided as a base at the front side of a laser of a reflection plane of the resonator, so that clockwise and counter-clockwise circular polarizations, which have slightly different frequencies to each other, are generated.  If a laser, such as a semiconductor laser, is arranged to have an eigen-mode with a linear polarization, a pair of elements can be employed for rotating a polarization by 90 degrees by one emission-and-return through an element, for example, quarter-wave plates.  The device does not require strong magnetic or electric fields, and can easily generate lights which are a constant strength.  Thus the device can be miniaturized and high efficiency can be obtained.

Abstract: "AUTOMATIC CONTACT-PIN SETTING APPARATUS FOR TESTING AN "OFF-GRID" PRINTED CIRCUIT"                 ABSTRACT OF THE DISCLOSURE     This machine essentially comprises: a contact pin feeding head which drives contact-pins through holes in the adaptor having a pair of frames made fast with each other, but mutually movable, each of which carry one of two parallel superimposed perfo-rated plates. The relative mobility of the two frames and accordingly of the two adaptor plates, enables alignment, as the case may be during the step of inserting each contact-pin, of two homologous holes along the vertical line through the contact-pin feeding head. The various steps are controlled by a processor which has the configurations of the holes formed in the two plates, respectively, stored therein.

Abstract: VARIATION AND CONTROL OF BOND FORCE Abstract of the Disclosure A lead wire bonding machine is described for ball bonding the end of a lead wire held in a bonding tool to a die pad of an integrated circuit chip and for wedge bonding a segment of the lead wire spaced from the ball bond to a lead frame finger during successive ball bond wedge bond cycles.  The bonding machine includes a variable linear drive such as a solenoid or small linear motor coupled to the bonding head for applying the first bond force to the bonding tool during ball bonding and the second bond force to the bonding tool during wedge bonding.  A control circuit coupled to the solenoid or other variable linear drive delivers a first current having a desired profile or amplitude wave envelope for applying the first bond force with a first force profile during ball bonding to die pads and by delivering a second current having a desired profile or amplitude wave form for applying the second bond force with a second force profile during wedge bonding to lead frame fingers.  A wave form generator generates the wave form envelopes for  achieving the desired force profile so that the bond force may be varied according to the force profile during bonding at a particular site.  Thus, the bond force may be varied and modulated according to the welding requirements at different die pads or lead frame fingers and according to the composition of the constituent metals of the lead wire and bonding substrate.

Abstract: Phosphoric Acid Crystallization Process Abstract The present invention discloses a new method for obtaining a crystallized phosphoric acid of relatively high purity starting with conventional phosphoric acid.  The new method is based on crystallization of orthophosphoric acid hemihydrate from the phosphoric acid.  Massive nucleation which would lead to the formation of unprocessable masses is avoided in the new method by providing unusually large amounts of fine relatively pure seed crystals of orthophosphoric acid hemihydrate and operating the crystallization process under conditions which favor crystal growth on the seed crystals and disfavor the occurrence of secondary nucleation.  To prevent the crystallizing magma from reaching a viscosity which would render further processing difficult the present invention provides for recycling raffinate in an amount suf-ficient to maintain the solids content of the crystallizing magma below about 40%.

Each loop portion wraps around an edge of the straight portion of the next adjacent link.  An additional portion is added to the inner side of the bight of the loop member and defines  a  curved bearing  surface  contiguous with the bearing surface defined by the bight.  The side edges of the bearing  surface  taper  so the  bearing  surface  is reduced in angular extent as the distance from the bight increases.  This allows the additional bearing portion to clear the sprocket wheel which drives the links of the chain.    The  additional  bearing  surface  significantly reduces  wear  of  the  rods  thus  increasing  life expectancy.

Abstract: 1,002,250. Digital data storage. SPERRY RAND CORPORATION. April 14, 1964 [April 23, 1963], No. 15314/64. Heading G4C. [Also in Division H3] In an associative matrix memory, each column storing a word is provided with an additional element which stores a parity bit for the corresponding word. An improved distinction between match and mismatch of a search word with a word in the store is thus obtained in the case when the search word and stored word differ by only one bit of data since the parity bits then also differ so that an enhanced signalto-noise ratio is obtained. The memory described is a thin film magnetic matrix with non- destructive read-out similar to that described in Specification 854,153, there being a storage film and a read-out film for each bit storage location. Words are stored in columns 20-0 &c. and consist of three data bits stored in cells 12-1 to 12-3 &c. and a parity bit stored in cells 12-P &c. A search word also comprising three data bits plus a parity bit is stored in a register 56 and causes currents of a polarity corresponding to the value, " 0 " or "1," of the corresponding search word bit to be applied to row lines 18-1 to 18-3, 18-P. If there is a mismatch at any storage cell, an output current is produced on the associated column sense line to provide an output at 62 indicative of the mismatch. The effect of the extra parity bit row is that the complete search word will always either equal a stored word or differ from it in at least two bit positions (including the parity bit position) so that the possibility of noise being incorrectly sensed as indicating a mismatch, is obviated. The column sense windings are of circuitous form, as shown at 34-40 in order to reduce selfinductance and to minimize the pick-up of extraneous signal. In a modification (Fig. 2, not shown) each parity bit cell is provided with an individual column sense line, connected, together with the column sense lines for the remaining bits of the column, to an OR gate.
