Patent JP-S63234320-A (JP)
Title: Adder
Inventor: KUDO TSUNEAKI
IPC: G06F7/50
Filed: 1987-03-23
Abstract: PURPOSE:To realize a compact adder together with the fast propagation of a carry by connecting alternately the prescribed number of adders of both positive and negative logics via inverting circuits for transmission of the carry. CONSTITUTION:For instance, two positive logic address and two negative logic adders of Manchester types containing driving inverters are connected alternately to each other so that the delayed transmission of a carry due to a transfer gate is evaded. An inverting circuit is set at the output side. In such constitution, it is not required to use the inverter circuits among adders to secure the coincidence between polarities of the carries to be transmitted in case the adders of the same logic are used. As a result, a compact adder is obtained and at the same time the carry propagating speed is increased.

Title: Error detecting and correcting method for multi-track digital recording and reproducing device
Inventor: TERANISHI MASARU
IPC: G11B20/18
Filed: 1984-04-04
Abstract: PURPOSE:To improve the detecting/correcting capability of a burst error in the width direction of a medium by rearranging a fixed number of subsequent error correction groups in the form of a set after formation of the error correction groups and performing the error detecting/correcting processing after attaining the adverse rearrangement to those error correction groups to set them back to an original array. CONSTITUTION:The even tracks are delayed by an amount equivalent to a set, and bit trains S11, S13, S15, S17 and S19 of odd tracks of the 1st set equal to the head irregular part are shifted to the position after bit strings SL1, SL3, SL5, SL7 and SL9 of the last set of the corresponding track. For a medium that is recorded under such an array, the burst errors are produced to four tracks at a position enclosed by a frame E owing to the injuries of the width direction, for example. Under such conditions, the record information is read as it is and then an original array is reset. In such a case, the burst errors are divided into errors of two tracks TRK4 and 6 of a set S2 and errors of two tracks TRK3 and 5 of a set S3. Then the correct data can be restored by an error correction code that can correct the errors of two tracks.

Title: Electric discharge machine
Inventor: TOODA HARUMASA
IPC: B23Q1/62
Filed: 1984-04-04
Abstract: PURPOSE:To reduce the flection produced in a bed as well as to make highly accurate electro-discharge machining attainable, by forming a moving mechanism between members into a sliding mechanism by means of surface contact, while uniformly dispersing load of each member on the bed. CONSTITUTION:A vertically long lower guide rail 13 in convex form corresponding to a sectional concave hollow of an upper guide rail 12 is laid down on the backside of a saddle 4 at a position being slidable to the upper guide rail 12. Likewise, an upper guide rail 14 is laid down on the saddle 4 inplace of a table guide rail, and a lower guide rail 15 is also laid down on the backside of a table 6 as in case of the backside of the saddle 4. Thus, in time of electro-discharge machining, even if the saddle 4 is moved in a Y-axis direction, load of the saddle 4, the table 6 and a work is uniformly disperse over the whole upper guide rail 12 of a bed 1, that is, uniformly loaded on the bed 1. Therefore, when the saddle 4 is moved and an end of the saddle 4 runs on a reinforcing rib, shifting to a position where the rib is none, the load imposed on the bed 1 is in no case one-sided, thus flection delta of the bed 1 reduces and a waving phenomenon comes to nothing.

The sensible image is thus formed. The sensible image is thereafter cooled to restore the hydrophilicity, by which the adherability to the transfer medium 1 is degraded and the sensible image is migrated by contacting with the transported material 8 to be transferred, by which the image is recorded.
