Abstract: @ A radiation image read-out apparatus comprises a stimulating ray optical system for exposing a stimulable phosphor carrying a radiation image stored therein to stimulating rays, a photodetector for detecting light emitted by the stimulable phosphor upon exposure to stimulating rays, and a light guide member for guiding the emitted light to the photodetector. A dichroic optical plane which selectively reflects either the stimulating rays or the light emitted by the stimulable phosphor and selectively passes the other is positioned in an optical path or the light guide member. The stimulating ray optical system is positioned so that the stimulating rays directly impinge upon the dichroic optical plane and come out of a light input face of the light guide member positioned close to the stimulable phosphor by being reflected by or passed through the dichroic optical plane. The light input face of the light guide member is preferably provided with a film for preventing reflection of stimulating rays.

Abstract: A carton (8) formed of paperboard coated with one or more liquid impervious layers and particularly adapted to aseptically package a liquid foodstuff such as milk or fruit juice. The carton is formed directly from a continuous web, wherein the paper fibers in the web are oriented in the direction that will parallel the horizontal axis of the formed and filled carton. The carton is in the form of a rectangular parallelepiped having a fin seam (26) running along its two side walls (16, 18) and its bottom wall (20). Each of the four narrowest edges carries a triangular flap ear or corner fold (30, 32, 34, 36) normally folded against the side wall of this carton. One (30) of the top triangular ears carries a pair of score or perforated lines (60, 62) which extend into the top wall, this ear swinging away from the carton upon opening, to thereby define a reclosable pour opening upon rupture of the score lines. The carton of this invention exhibits a flat top (22), free of a fin seam, and hence, is better suited for graphics (e.g. trademarks, brand names, color combinations), than other prior art containers which have a fin seam on their top surface. In the embodiment having perforated lines on the triangular ear, the perforated lines are so formed that no perforation crosses or intersects a fold line, thereby inhibiting delamination of the layers coated on the paperboard.

Abstract: A document creating apparatus allows the insertion of strings of characters within a display area of a boundary figure to have good balance. The display area of the strings of characters is compared with that of the boundary figure. The strings of characters are reduced or enlarged orthe boundary figure is enlarged or reduced in accordance with the comparison result so as to display the strings of characters and the figure with good balance. An input section (1) is used for inputting character information, character input positioning coordinated information and boundary figure information. A display section (7) displays the character information and the boundary figure information. A boundary centre calculation section (5) calculates the center of the boundary figure. A boundary information holding section (4) stores position coordinate information, and boundary figure information at the center of the boundary figure. An enlarge/reduce section (8) serves to enlarge or reduce the characters orthe boundary figure.

Abstract: To prove safe operation of a conventional computer based system the processing hardware is multiplied in parallel channels and the individual results cross-correlated to determine the correct result. The proposed arrangement aims to achieve a comparable level of safety using a single processor (7) channel operating cyclically by correlating results computed during different operating cycles (Figure 1, Figure 2). The processor 7 is also checked frequently, preferably during each cycle to guard against processorfauhs. The cyclic redundancy approach is then able to disqualify results arising from common mode interference and spurious errors in the processor inputs (1).

Abstract: Arrangements of picture-element electrodes of a color liquid-crystal display apparatus. In a color liquid-crystal display apparatus using mosaic arrangements, the same color of picture elements which are driven by the same signal electrode are alternately arranged right and left. Accordingly, all the necessary thing is that the same color of picture signal is applied upon the same signal electrode in spite of the mosaic arrangement. Thus, a circuit is rendered unnecessary which switches a color image signal of an analog line memory, so that the driving circuit is extremely simplified.

Abstract: A burner for gaseous or liquid fuel for heating furnaces includes a ceramic combustion chamber (20) for incomplete combustion of the fuel with primary air from which hot gases exit at high velocity through a constricted outlet (24). The combustion chamber is surrounded by a chamber (42) for the preheated remainder air necessary to complete combustion. Out of this chamber high velocity jets of air issue through nozzle openings encircling the combustion chamber outlet. Energy is saved and simple construction maintained by providing a tubular heat recuperator (4, 7, 9) rearwardly of the combustion chamber in which a cylindrical wall of temperature resistant steel passes to separate the recuperator into two annular chambers (10,11) and extends forward over a large part of the axial length of the combustion chamber so as to form an outer boundary of the remainder air chamber. The forward extension of the cylindrical wall (9) has an inturned rim constituting the ring-shaped nozzle carrier (33) in which the nozzle openings for the remainder air jets are provided. The combustion chamber is clamped between its spring-loaded fuel pipe (16) and the nozzle carrying rim (33) of the cylindrical wall (9).

Abstract: An integrated circuit including a field effect transistor; (Q,) formed on a GaAs semiconductor crystal substrate (10) is produced by implanting ions of an n-type impurity into the substrate (10) and heat-treating it at a high temperature to activate the implanted layer into an active layer (13, 14, 15). The substrate (10) is initially formed with a neutral impurity such as In and thus the substrate initially substantially only contains electrically neutral impurities. The field effect transistor thus produced has a precisely defined threshold voltage and all the transistors produced in the same device have a threshold voltage within a narrow predetermined range. This provides much improved performance, particularly when a differential amplifier is formed by a pair of field effect transistors in the integrated circuit.

Abstract: 57 An integrated circuit unity gain buffer amplifier suitable for low voltage operation in which the input signal is applied to the base of a common emitter NPN transistor first stage (Q1). The collector of the first stage is connected to the base of an emitter follower NPN transistor second stage (Q2). The emitter of the second stage is connected to the base of an emitter follower PNP transistor third stage (Q3). The collector of the first stage is loaded by a constant current source (4) and its emitter is connected through a resistance (R1) to ground. The collector and emitter of the second and third stages respectively are connected together through a resistor (R3) to the supply voltage (Vcc). The emitter of the second stage is connected through a resistance (R2) to ground. The collector of the third stage is connected both to the output terminal (6) and to the emitter of the firs! stage. This allows the circuit to operate at a very low supply voltage without any transistor operating in practical saturation.

Abstract: Memory address signals (UA, LA) consisting of upper and lower address signals output from a memory access circuit (11) are retained by an address counter (12). An address comparator (16) compares the upper address signal retained by the address counter (12) and the next upper address signal (UA) from the memory access circuit (11). If these upper address signals coincide with each other, a multiplexer (13) is controlled by a timing control circuit (17), and only the lower address signal (LA) held by the address counter (12) is supplied to a memory (18) via an address bus (14). However, if the above upper address signals do not coincide with each other, the multiplexer (13) is controlled by the timing control circuit (17). In this case, the upper and lower address signals retained by the address counter (12) are multiplexed, and the multiplexed signals are supplied to the memory (18) via the address bus (14). The timing control circuit (17) also supplies a row address strobe signal (R AS) and a column address strobe signal (C AS to the memory (18).
