Filed: 1971-04-21
Abstract: 1343454 Multiprogrammed computers SINGER CO 21 April 1971 [27 April 1970] 10519/71 Heading G4A A multiprogrammed data processing system is disclosed. A digital electric data handling system comprises a plurality of data transmitting and receiving devices 18, each being adapted to transmit and receive data asynchronously with respect to each other and to emit an interrupt signal when it requires to receive or transmit, a main memory 10 for receiving and storing data (including programs), the memory having separate program sections (not necessarily physically adjacent) for respective devices 18, means 12 for executing a program in the memory, and for interrupting a program in response to an interrupt signal, means for resuming execution of the program after the interrupt has been serviced, and means for ceasing the execution of the program in one program section and commencing execution of the instructions in another memory section after a predetermined time period and a branch instruction, the period being measured from the time a program in a memory section has been executed without interruption or a branch instruction. The system may be a point of sale system having peripheral devices 20 including alpha numeric keyboards, typewriters, punched tape or card readers, or printers and may be used with credit card verification or accounting systems. Up to ten peripheral units 20 are connected to each input/output control unit 18, each unit 18 being independent of the other units 18. Data is entered in a 7 bit USACII code but is converted to a 6 bit BCD code and transmitted in series. Also provided are magnetic disc and tape stores 28, 32 for storing data from the peripheral devices and a telephone line connection to another computer 34. Main memory (Fig. 4, not shown).-This is a magnetic core store which is notionally divided into the program sections, each section being of variable size and holding the program interrupt data, index data and error data for address errors, attempted illegal access to a protected area of a common area, or a data fault. The common area is shared by all the programs and includes a protected area holding common programs. Supervisory control unit (Figs. 10 and 11, not shown).-This controls operations and can effect functions such as add, subtract, multiply, divide, branch, compare, begin &c. and also performs error checks. It also controls a time counter which is set each time a new program section is executed and, after a predetermined time without interruption, the next program section in a section sequence order is moved to using a switch routine. This prevents one program section from completely blocking the system. Program execution may also be halted by power failure.

Title: Dopant sources for use in manufacture of semiconductor devices
IPC: H01L21/223
Filed: 1970-03-05
Abstract: 1292374 Silicon; phosphides and arsenides of Ga and In INTERNATIONAL BUSINESS MACHINES CORP 5 March 1970 [1 April 1969] 10551/70 Heading C1A [Also in Division H1] A doped semi-conductor material, e.g. Si doped with As, which is homogeneous and can  be used as a dopant source in a capsule diffusion  process is obtained by introducing finely ground semi-conductor material and a dopant or dopant containing material into an enclosure, evacuating the enclosure, heating the materials to a temperature less than the m.p. of the semiconductor material, whereby dopant vapour is given off by the dopant or dopant containing material and diffuses into the semi-conductor material, and continuing to heat the materials until a condition of substantial equilibrium is established within the enclosure. Preferably as shown in the Figure, the enclosure 10 is elonggated, the semi-conductor material, and the dopant or dopant containing material being located in opposite ends 11, 12 respectively of the enclosure. The enclosure is heated in a two zone furnace 15 after evacuation and sealing so that the dopant is heated at a temperature sufficient to vaporize it, e.g. 500-600 C. and the semi-conductor material is heated to a temperature which is higher than the first, e.g. 800-1050 C. The dopant may be P, As, Sb or B. If desired, the process may be performed to produce a first doped product which is then used again as the source of dopant in the process of the invention to produce a less heavily doped product. When used in the capsule diffusion process for producing semi-conductor wafers, the dopant sources produced by the process of the invention exhibit a substantially constant dopant vapour pressure (Fig. 4, not shown). The doping of GaAs, InP, GaP, and InAs and related ternary compounds with Zn, Cd, Se and Te is referred to.

Abstract: 1,042,789. Digital-electric calculating apparatus. BELL PUNCH CO. Ltd. March 16, 1965 [March 21, 1964], No. 10979/65. Divided out of 1,042,785. Heading G4A. An electronic calculating apparatus includes a decimal register with means L (Fig. 3, not shown), for indicating the position of the decimal point of a number stored in the register, the position being controlled by a ring counter D.C. wherein stepping pulses applied to the counter D.C. pass through a plurality of gates D.G. controlled by a bi-stable device B.D. The methods of setting numbers in the register with their decimal points, and of performing division is as described in Specification 1,042,787. Multiplication.-In a first method in which a multiplicand in the register is multiplied by successive digits set on a bank of multiplier keys (see Specification 1,042,786), when the position corresponding to the depressed decimal point key D.K. is reached, a transistor T.R. is rendered conductive, setting the bi-stable device B.D. to pass pulses through a gate D.G.2 to step the counter to the position corresponding to the switch D.K. Entering of subsequent digits permit passage of one pulse through a gate D.G.3 and eleven pulses through the gate D.G.2 until the multiplier decimal point key is depressed placing a negative potential on a terminal D.P. to prevent the gate D.G.3 conducting and thus preventing further stepping of the decimal point. In a second method in which a multiplicand on the keyboard is multiplied by a multiplier in the register (see Specification 1,042,786), the bi-stable device B.D. is initially set through a gate D.G.13 and eleven pulses are added to the counter D.C. through a gate D.G.4 during each cycle until in the last multiplication stage the bi-stable device B.D. is unset through a gate D.G.9 and then set again through a gate D.G.7 at a time determined by the actuated keyboard decimal key D.K., thus stepping the counter decimal point a number of times determined by the multiplicand.
