Patent SE-8004005-L (SE)
Inventor: GORDON J P
IPC: H01L31/107
Filed: 1980-05-29
Abstract: Devices constructed according to the present invention provide low noise avalanche photodetectors. The devices are comprised of a sequence of at least four layers of semiconductor material of alternating opposed conductivity. In a first embodiment the layers form alternating homojunctions and heterojunctions at the interface between adjacent layers, and the bandgap of the layers on either side of the homojunctions decreases in the direction of the propagating signal. In another embodiment the layers form heterojunctions at the interfaces between adjacent layers; the layers are grouped into a sequence of pairs of layers where the bandgap of the two layers in each pair are substantially equal; and the bandgap of the layers in the sequence of pairs of layers decreases in the direction of the propagating signal. The effect of the structure of the multilayer device is to create traps for one sign of carrier and to prevent the trapped carrier from avalanching through amplification regions of the device.

Abstract: A device for emplacing a purse-string suture in a severed end of a colon or other tubular structure. The device is generally barrette-like and has teeth on the upper and lower jaws which are mutually opposed so as to compress the tissue placed between the jaws and to permit tissue to bulge out into spaces between the respective teeth. Each jaw is provided with a needle guide or track through which a straight needle and suture may be passed and in passing through the needle track it will pass through the bulged out portions of the tissue. To emplace a purse-string suture, the needle is passed through one of the jaws in one direction and then looped around and passed through the other jaw in the opposite direction. A cutting guide is provided for severing excess tissue to provide a suitable cuff.

Abstract: A watch-dog timer monitor for the control system of a power plant including a pulse monitor which measures the length of time between successive control pulses from an output port of a computer. In the event that any control pulses exceeds the preselected time interval, the pulse monitor sends a disable signal through a latch to the buffers in the path of the control signals. The buffers instantaneously transition to a blocked condition preventing any subsequent control pulses from reaching the control system of the power plant. A reset button is toggled to reset an initializer which restarts the program in the computer. A start-up delay is also provided to insure that no spurious control pulses reach the control system of the power plant during a warm-up period when the digital logic circuits are settling out.

Abstract: This invention relates to a collapsible container comprising a bottom unit (1:1'), four angle posts (7:7'), two longitudinal side walls, two end walls (11:11') and an upper unit (12:12') supported by the end walls (11:11'). The reason for the container being made collapsible is to make it possible to place a number of folded-up containers in an unfolded container of the same kind at so-called return freight. What characterizes the container of the invention is that the side doors (8:8') forming the side alls are collapsible to packages, which are pivotable relative to the angle posts (7:7'). Moreover, the angle posts (7:7') with intermediate end wall (11:11') are pivotable relative to the bottom unit, the folded-up container having such dimensions that there is room for it in an unfolded container of the same type.

Abstract: A locking device (1) serves to connect two parts (8) to one another. One of the parts has a non-circular, elongated hole (2), and a basic locking body (6) is arranged at the other part. Rotatably fastened to the basic body (6) is a connecting block (9), the guide end of which has a shape which can extend through the elongated hole and has laterally projecting ends. The connecting block (9) can be rotated between an engagement position in which the ends project beyond the periphery of the hole and a release position in which the ends do not project beyond the periphery. Normally the ends are in the engagement position. The periphery of the hole (2) interacts with the guide surfaces (9) like a cam curve in order to automatically rotate the ends into the release position when the connecting block (9) enters the hole (2). An elastic or flexible element (7) acts on the connecting block (9) and forces it into the locking position, but the connecting block (9) can be moved into the release position by hand. <IMAGE>
