Abstract: Metal vapour laser apparatus includes a laser tube 1 and a reactor chamber 6 in which is contained metal 8 which in this case is copper in the form of granules. Neon is introduced via one input port 9 of the chamber 6 and a halogen or halogen donor gas through another input port 10. Coil 7 surrounds the reactor chamber 6 and provides heating. Metal halide is formed at the surface of the metal and vaporised by heating. The buffer gas and metal halide are transmitted via conduit 11 into the laser tube 1 where dissociation of the metal halide and subsequent excitation of metal vapour is carried out to produce laser radiation.

Abstract: There is disclosed an apparatus capable of transmitting a moving image with smooth movement and with sufficient image quality, even through a transmission channel of a low bit rate. In this apparatus, with the received image, a significant area to be received with high image quality is designated on a monitor image frame. The image signal to be transmitted is entered, in the unit of a block, into an input terminal 40. Circuits 42 - 48, 52 - 58 constitute a frame-to-frame difference encoding circuit. A subtractor 42 releases the predicted error, and a DCT circuit 44 releases the DCT transformation coefficients. A masking circuit 46 masks the DCT coefficients released from the DCT circuit 44, in a smaller proportion in a block belonging to the significant area, and in a larger proportion in a block belonging to the non-significant area, according to the mask level signal 47. A quantization circuit 48 quantizes the output of the masking circuit 46.

Abstract: To stabilise the vertical position of adjacent concrete slabs, for example of airfield runways, mutually spaced, cylindrical, vertical holes are made centrically with respect to the joint. Annular undercuts (35) are subsequently produced in these holes (28) by means of an undercutting device. These undercut holes are provided with a separating means. Subsequently, a hardenable filling compound is poured in. After hardening, position stabilisation of adjacent components in the vertical direction results, while a horizontal expansion movement in the region of the joints can take place. <IMAGE>

Abstract: The present invention relates to a method of connecting subscribers to a telephone exchange in a manner to spread the risk of groups of subscribers being put out of order. Incoming subscriber lines are connected to a cross-connection frame which, in turn, is connected on the station side to the different line switch modules of the exchange, and the modules are divided into a number of subscriber groups. The cross-connection frame is divided into a number of frame modules where the size of each module corresponds to a line switch module. According to the invention, the incoming subscriber lines are connected in groups to the frame modules (8) so that geographically neighbouring subscribers, for instance subscribers in a residential quarter or area, are connected to the same module. The frame modules (8) are divided into a number of sub-modules (8a) corresponding to the number of subscriber groups (9a) in each line switch module, and the cross-connection frame is connected to the line switch modules (9) of the exchange, preferably by multipaired cables (10), so that the sub-modules of each cross-connection module (8) are connected to a respective line switch module (9). In this way, all sub-modules (8a) within each cross-connection module (8) is connected to different line switch modules (9), so that not all subscribers within one and the same geographical area will be put out of order should a fault occur on one line switch module.

Abstract: A hydraulic circuit device for construction machines wherein a first pressure regulator (130) for controlling the downstream pressure of first variable throttles (107, 107a) to a value corresponding to a first signal pressure is disposed between the first variable throttles of a directional control valve (47) for leftward running and a first running motor (57), and wherein a second pressure regulator (133) for controlling the downstream pressure of second variable throttles (108, 108a) to a value corresponding to a second signal pressure is disposed between the second variable throttles of a directional control valve (49) for rightward running and a second running motor (57). A negative pressure of either the first or second running motor, whichever is higher, is detected by a shuttle valve (136) as a maximum negative pressure, and signal switching valves (131, 135, 170) are caused to operate during combination operation in which the first and second running motors and at least one of a plurality of work machine actuators (53 to 56) are simultaneously driven, whereby themaximum negative pressure is imparted to the first and second pressure regulators as first and second signal pressures. Even when this enables a communication circuit (110) to be put into operation as the work machine actuators are put into operation during combination operation in which running and the operation of the work machine are simultaneously effected to thereby allow a pressure oil supply circuit (104) of the second directional control valve for rightward running and a pressure oil supply circuit (103) of the first directional control valve for leftward running to communicate with each other, differences in pressure across the first and second throttles become substantially equal to each other, thereby making it possible to secure a straight running capability.
