Abstract: 2.1 The undertaking of a so-called cold test for testing combustion engines is already known. This is carried out, however, only when the combustion engine is almost completely assembled and permits only two findings, that is that the combustion engine tested is either in order or not in order. Such a cold test does not meet the increasing quality requirements made of modern, high-performance combustion engines. In particular any faults are detected too late, which has an adverse affect on the economy of manufacture. 2.2 According to the invention intermediate function tests (18, 19) are carried out after one or more assembly stations (16, 17) in addition to a final function test. In this way any functional defects occurring can be detected in good time and by comparison with earlier measurements or master measurements precise findings can be arrived at on the nature of the defective function. 3. The procedure according to the invention is particularly suitable for the testing of combustion engines assembled on assembly lines (15), and also of gearboxes or the like. <IMAGE>

Abstract: A silicon oxide film to be used as an interlayer-insulating film in a semiconductor device is formed by a high pressure organic silane-O₃ CVD. A semiconductor wafer is placed in a reaction vessel and is heated at a temperature of 400°C. A mixture of an organic silane gas such as TEOS, HMDS and OMCTS and an ozone gas is introduced into the reaction vessel and the reaction is carried out at a pressure higher than the atmospheric pressure, preferably at a pressure of about 2 Torr to form a silicon oxide film having excellent properties. A life time of the ozone gas which serves as an oxiding agent and/or catalyst can be prolonged under the high pressure, and therefore a deposition rate of the silicon oxide film ca be increased and the flatness of the silicon oxide film can be improved. Therefore, the silicon oxide film forming process can be performed efficiently and a flatenning process after the formation of the silicon oxide film can be made simpler.

Abstract: A multitasking operating system permits application programs (and their developers) to influence a schedule of execution of program threads derived from the application programs. Each of the program threads is assigned a priority level and a dispatch class in which the thread resides. Based on these parameters, the operating system schedules the threads for execution in the following manner. The operating system queues the highest priority thread which is available for execution from each dispatch class onto a run list for execution by a processor. The highest priority thread on the run list is executed first. An application program thread can change the dispatch class in which another program thread resides. An executing program thread can also voluntarily yield to a specified program thread in the same dispatch class or permit the highest priority available thread in the same dispatch class to be queued on the run list with itself being available and in contention for the run list.

Abstract: Hitherto, a coordinate reading system has included a coordinate indicator (62) containing a coil (63) for generating an AC magnetic field and a tablet (51) upon which many sense lines are laid and in each of which a signal is induced. The sense lines are scanned and switches switch between them to calculate the amplitude of the induced signal and hence the position of the coordinate indicator. 
     In the present invention, the sense lines (52-56) have a castellation shape (54, 55, 56) and/or a series of connected triangular shapes (52, 53) and/or curving variations of those shapes. A selecting circuit (57) and calculating circuit (59) sequentially processes the induced signals (s52-s56) in the sense lines. Thus no scanning is required, the tablet is simplified and the coordinate calculation speed can be increased.
