IPC: G03B42/02
Filed: 1988-04-15
Abstract: A radiation image recording and read-out apparatus comprises a recording and read-out unit (20) for recording a radiation image on a stimulable phosphor sheet and reading the radiation image therefrom, a shutter (16) moveable between a masking position that prevents impingement of radiation upon a part of the stimulable phosphor sheet and a retracted position that allows impingement of radiation upon a single image recording region of the stimulable phosphor sheet, and a shutter operating device for moving the shutter between the masking position and the retracted position. The recording and read-out unit is moved by a unit movement device to move the stimulable phosphor sheet in the same plane at an image recording position in the recording and read-out unit. A system is provided for operating the shutter operating device to move the shutter to the masking position, and operating the unit movement device to move the recording and read-out unit so that the uncovered portion of the stimulable phosphor sheet at the image recording position that is not covered by the shutter changes sequentially.

Abstract: In a programming device for handling equipment, the centre part (1) is connected to the member of the handling equipment to be programmed. Arranged around the centre part (1) is a sleeve (2) which is guided by the hand of the programmer. Arranged between the centre part (1) and the sleeve (2) are measuring systems which measure the relative movements between the sleeve (2) and the centre part (1) which result owing to the guidance of the sleeve (2). These measuring systems consist of a slide (6) which is linearly guided on the centre part (1) and has a ball (8) arranged between two pins (5) which are connected to the sleeve (2). The pins (5) are surrounded by springs (3) which are supported, on the one hand, on the sleeve (2) and, on the other hand, on arms (9) of the slide guide. The movements of the slide (6) relative to the centre part (1) are measured.

Abstract: First, silicon wafers are formed by cutting silicon monocrystalline ingot into slices (STEP 1). Then, back side and main surfaces of the wafers are subjected to lapping and etching processes (STEP 2). Next, the wafers are submerged into treatment solution and ultra­sonic waves are applied to the wafer surface via the treatment solution to clean at least one of the surfaces of each of the wafers and form gettering damage on the wafer surface (STEP 3). After this, the main surfaces of the wafers which have been subjected to the cleaning and damage-forming process and on which semiconductor elements are to be formed are polished into mirror finish.

Abstract: Input pulses (N) are applied to toggle a first bistable (BS1) whose output provides clock signals to a monostable timer (MS1) whose period is set to the duration of one cycle of the input pulses (N) at a critical frequency. A second bistable (BS2) enables a third bistable (BS3) and a counter (CTR) only if an edge of a pulse from the timer (MS1) occurs in an interval of the clock signals from the bistable (BS1). Thereafter the counter (CTR) is clocked by pulses which are derived from the clock signals of the first bistable by the third bistable (BS3). The counter (CTR) provides an indication after a predetermined number of the input pulses (N) which have reached the critical frequency. An output signal derived from the indication may be maintained by a fourth bistable (BS4).

Abstract: In a laminated material comprising a polyolefin-based film bonded to a metal sheet (M), the polyolefin-based film is a multi-layer co-extruded film comprising an inner layer (B2) of a bonding resin which is an acid-modified polyolefin resin containing carboxyl or anhydride groups and an outer layer (B1) of a polyolefin or polyamide containing 0.15% to 0.5% by weight of a finely divided non-reactive low-opacity synthetic silica having an average particle size on the range 0.5 to 5 microns. Another thermoplastic film (A1,A2), such as a biaxially oriented polyester film, may be simultaneously laminated to the other surface of the metal sheet. The lamination process involves heating the laminated material to effect bonding and then quenching the laminated material rapidly and uniformly from above the melting point of the polyolefin to below its softening point. The laminated material may be used in the formation of can ends and can bodies, which can be double seamed together without fibrillation of the polyolefin-based coating.

Abstract: The invention relates to a miller for removing a road surfacing. When road surfacings are removed by means of relatively large millers, work remains to be done in the area of the manhole covers, gullies, road junctions or the like, which work cannot be carried out with the large miller. According to the invention, provision is made for arranging on the miller a supporting arm (30) having a milling head (39, 39a) arranged on its front end. The supporting arm (30) is adjustable transversely to the longitudinal axis (14) of the miller as well as along this axis so that, when the miller is stationary, the milling head (39, 39a) can be adjusted in a plane in the X-direction and Y-direction. By superimposing the regulating movements in the X-direction and Y-direction, any curve can be milled with the miller according to the invention so that the work remaining to be done can easily be carried out. <IMAGE>

Abstract: Joining system for joining wall panels (1, 2, 3) to form a box-like housing, which panels are composed of rectangular flat plates having a core (17) of electrically non-conducting material and having two principal surfaces situated opposite each other and covered by a layer of electrically conducting material. In the peripheral surfaces a groove extends parallel to the said principal surfaces. The groove walls are embodied such that the two principal surfaces of each plate each terminate in a wedge-shaped peripheral portion along the edges. The panels have to be joined to each other in twos by means of two L-shaped sections (13, 14) of electrically conducting material of which the ends of both legs are provided with a groove whose cross-sectional shape is matched to the shape of the wedge-­shaped peripheral portions. The wedge-shaped peripheral portions of the panels are pushed into the grooves in the ends of the legs of two suitably dimensioned L-shaped sections to produce the joint between two panels and the panels subsequently are pressed with force into the said grooves in the L-shaped sections.

Each instrument is allocated a serial number depending on its position along a seismic profile under investigation. Each instrument then determines the difference between its own serial number and that which it receives by radio (receiver 14) and which is the one allocated to the first data- acquisition instrument in its group. Depending on the measured difference and subject to certain limitations, each data- acquisition instrument is assigned its own transmission frequency.
