IPC: G11B20/18
Filed: 1989-04-26
Abstract: A data encoder is set to an initial condition by encoding preliminary symbols. The encoder is then used to encode the data to generate ECC symbols. The data and the generated ECC symbols are then recorded on a disk as code words. Thereafter, when a data code word is read it is again encoded in the initialized encoder to generate new ECC symbols. If the data read from the disk is one or more symbols out of synchronization, errors due to the initial condition will be found. The locations of the errors due to mis-synchronization will be in symbols corresponding to the initial condition, that is, in the preliminary symbols and beyond the boundary of the code word data, indicating the synchronization error. Alternatively, the locations of errors due to defects in the disk or misinterpretation of the data signal are within the code word data. Thus a mis-­synchronization of one of more full symbols can be readily detected.

Abstract: An agricultural baling machine controls the density of bales of crop material discharged therefrom by monitoring the stress experienced by a reciprocably driven plunger assembly (22) employed to apply a compactive force to crop material introduced into a bale case (20). The bale case (20) is comprised of rails (54, 56) which are positionably adjustable in response to applied tension in a manner whereby the dimensions of the bale case (20) are changeable, thereby facilitating a change in the degree of resistance caused by the bale case (20) to crop material movement therein. Signals produced by stress sensors (124, 126, 128, 130) mounted relative to the plunger assembly (22) are analysed by a programmed signal processor (200) which accordingly generates a control signal for controlling a servo valve (61). In response to the control signal the servo valve (61) governs the degree of tension applied to the bale case rails (54, 56) and thereby adjusts the degree of resistance to crop movement in the bale case (20). The analysis performed by the signal processor (200) results in the generation of a pulse width modulated control signal that enables the servo valve (61) to adjust the degree of resistance to crop movement in the bale case (20) so that the stress experienced by the plunger assembly (22) is maintained near a predetermined level in accordance with desired bale density.

Abstract: A semiconductor device that has a feature in the spatial relationship between the wirings in a multi-level wirings and the intermediate insulating films. In the lower part of the second and/or subsequent levels of wirings there exist intermediate insulating films that have a pattern which is the same as the pattern of the wirings. Because of this arrangement, the intermediate insulating film does not exist between the wirings on the same level. The first structure of the multi-level wiring has the intermediate insulating films formed in wall-like shape, with the lower end of the intermediate insulating films reaching an underlying insulating layer formed on the surface of the semiconductor substrate. The second structure of the multi-level wiring is a quasi air gap metallization structure. 
     As a result of realization of such structures, in the semiconductor device according to the present invention, the parasitic capacitance due to the coupling capacitances between the wirings can be reduced markedly compared with a semiconductor device that has a structure in which the spaces between the wirings are filled with the intermediate films.
