Abstract: An alignment system for aligning a mask and a wafer into a predetermined positional relationship, by using alignment marks provided on the mask and the wafer, is disclosed. In this system, light from a light source is directed to the alignment marks of the mask and the wafer and, then, the light from these alignment marks is detected by an accumulation type photoelectric converting device, for alignment of the mask and the wafer. The accumulation time of the photoelectric converting device is controlled to be sufficiently longer than or to be equal to a multiple, by an integral number, of the period of relative and natural vibration of the mask and the wafer. This makes it possible to reduce the effect of the relative vibration of the mask and the wafer upon the alignment result and, therefore, makes it possible to enhance the alignment precision.

Abstract: Measuring system for carrying out the method for determining the progression rate of bulk materials, in which the bulk materials are transported continuously via a conveyor device equipped with a driving device. At the same time, the conveying device is periodically moved with a determinable lift perpendicularly to the conveying device. During the lifting operation, the lifting force is measured by a dynamometer device. The lifting speed is simultaneously detected by a sensor device, the progression rate being calculated from the lifting-speed signal and the lifting-force signal in an evaluation device by means of a computing operation. In the evaluation device, the periodic lifting force is modulated with the periodic lifting speed and this output signal is integrated over time. In the integration of the output signal over a whole number of periods, the inertia forces thus measured, which originate from the driving speed (Coriolis force), give a value which corresponds to the progression rate. <IMAGE>

Abstract: In order to automatically restore a normal switching position of a relay, armature from an accidental OFF switching induced by external impact or the like, the output of the relay is monitored and is applied to a differentiating circuit. A comparator is provided to reflect on and off operations of a main switch. In the event that the output of the relay falls suddenly, the differentiating circuit outputs a pulse to a wave-­shaping circuit (e.g., Schmitt trigger). An gate circuit is supplied with the outputs of the wave-shaping circuit and the comparator. The output of the gate circuit momentarily allows a relay driver to actuate the relay in response to the undesired change in relay status, and hence the relay armature resumes ON switching position.

Abstract: In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and reduces access time. The format has three layers. A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes. A second, logical layer is used to address the physical layer and to collect together sectors to form multiplicity of separately addressable spaces, with space having a distinct functional utility. As a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information. At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders. These are logically, rather than physically, defined collections. A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time. At the logical layer, the disk is divided into three main areas, each separately addressable. The first main area is broken down into two sub-areas. The first sub-area (12) is available to the host computing system for its use; the second sub-area (14 and 16) is used for replacement of the bad blocks. The second is for format information. The third main area (18) is for diagnostics. Handling of bad blocks is controlled by a hierarchically layered process. A portion of each disk, distributed across the medium, is reserved as spare sectors to replace defective sectors. After a bad sector is replaced, future attempts to access the bad sector are redirected (i.e., revectored) to the replacement sector. For the simplest revectoring, the bad block is replaced by a replacement block in a known location. If that cannot be done, multiple copies of the replacement block's header are stored in the bad block's data field and the copies are compared to find the replacement address. If the comparison fails, or the header cannot be read, a back-up table is available to match the available replacement addresses with the original address which was replaced. A special code is used to identify blocks wherein the medium is good but the contents of the block are logically corrupted.
