Abstract: Ink ribbon cassettes for typewriters and office machines of similar construction are subject to a number of different design requirements; in particular they should be easily replaceable with a one-handed operation. Since the transport elements, for example, for the carbon ribbon in such cassettes are situated inside the housing, these cassettes are very expensive. In order to avoid this, ink ribbon cassettes with exchangeable ink ribbon spools have been disclosed. To this end, the dish-shaped base element (2) of the cassette casing (1) has a hinged lid (4). The object of the present invention is to make it possible to close the opening of the base element (2) simply and effectively. This is achieved by arranging that in the closed position, the lid (4), at least in the region of the two arm-like projections (22, 23), is mounted in a lowerable manner between the edges (24, 25, 26) of the base element (2). In this way, a secure closure of the base element in the region of the ink ribbon guide arms is achieved. <IMAGE>

Abstract: An n-p-n heterobipolar transistor (HBT) has a base layer (3a) composed of SiGe and emitter layer (4a) and collector layer (2a) composed of Si. In such Si/SiGe HBTs, the hole injection into the emitter region is reduced and the emitter efficiency is consequently improved. To increase the current driver characteristics, the HBT according to the invention is combined with an Si/SiGe MODFET (modulation-doped field effect transistor). HBT and MODFET are produced from the same semiconductor layer sequence. <IMAGE>

Abstract: Rotor structure of a motor. Yokes (13) each equipped with a permanent magnet (14) fixed to its outer circumference of a rotor core (12) with predetermined gaps between them in such a manner as to form recesses (20) between the yokes (13).

Abstract: The present invention provides a compressor for an injection compres­sion molding machine, which has con­trol characteristics superior to these of a hydraulic compressor, and which is therefore capable of molding a material with a higher accuracy and better re­producibility. A compressing pin (32) is fixed to the tip portion of a ball screw (29) engaged with a ball nut (24) con­nected to a servomotor (19), which is provided on a movable platen (3), via a power transmission (35). In conjunction with the rotation of the servomotor, the compressing pin is moved axially with the ball screw to project from the mov­able platen toward a metal mold (100) and compress a molten resin packed in the metal mold.   
     ABSTRACT 
     A compressor unit of an injection-compression molding machine is provided, which is higher in control performance than a hydraulic compressor unit, and is capable of performing high-accuracy molding with satisfactory reproducibility. 
     A compression pin (32) is fixed to the tip end of a ball screw (29) threadedly engaged with a ball nut (24) which is coupled, by means of a power transmission mechanism (35), to a servomotor (19) attached to a movable platen (3). As the servomotor rotates, the compression pin axially moves together with the ball screw, thereby projecting from the movable platen toward a die (100) to compress molten resin filling the mold.

Abstract: A pressure activated reserve battery is capable of being activated by increasing external or environmental seawater pressure as the device is lowered or sinks to depth, without benefit of an external pressure hull. Pressure compensation, balancing of external seawater pressure and internal electrolyte pressures continually after activation of the device precludes the use of a pressure hull. In the battery, made up of several reserve cells each cell (2) includes an electrolyte reservoir 16) and a cell electrode assembly (18.20). A first barrier (24) having a pressure rupturable disc (26) is arranged to provide a fluid-tight separation between the electrode assembly and the electrolyte reservoir. A collapsing cup (42) integrally attached to the wall of the electrolyte reservoir (16) is located within the reservoir with the open end facing the first pressure rupturable barrier (24). A second pressure rupturable barrier (40) is located on the external end of the cylindrical electrolyte reservoir (16). All reserve cell assemblies (2-10) are located within an external housing (30,34,46) filled with an electrically non-conductive fluid having a first end cover (46) containing a third pressure rupturable disc (48). A flexible bladder (52) is provided within the external housing to isolate the fill fluid from the end cover (46) and the third rupturable disc (48). The application of a predetermined external pressure on the housing results in an initial collapse of the third rupturable disc (48) and a subsequent application of the   external pressure to the bladder (52) to pressurize the fill fluid. The pressurization of the fill fluid to a predetermined level results in a rupture of the second rupturable discs (40) and the pressurization of the electrolyte by a collapse of the integral cups (42). Finally, the pressurized electrolyte is effective to breach the first rupturable discs (26) to enable the electrolyte to be forced into the electrode assemblies to activate the battery.

Abstract: The invention concerns the cementaion of an oil bore hole or of similar bore holes. 
     According to the invention, the theoretical acoustic impedance of cement is evaluated as a function of some theoretical cementaion parameters, this impedance is corrected as a function of the actual meeasured density of the cement slag during pumping, a correlation is established between with the depth as a function of the data recorded during cementation and of the bore hole geometry, and a value Z = f (depth) is deducted therefrom, which gives access to the prediction of the accoustic atteenuation curve : 
CBL (prediction ) = f (depth) corresponding to the parameters of the actual cementation. 
     By comparison with the (measured) CBL curve, the exact zone where a secondary or repair cementation will be necessary is deducted.

The block, and the means to force it along the chute, is larger than the chute (2) whereupon the two channel members (6) are moved apart. This holds the bag in position on the chute. Simultaneously, pressure is applied to counteract the expansion of the chute (2) by hydraulic cylinders (22).
