Abstract: A posted-write queuing program for writing informa­tion sectors to disk sectors includes error-handling rou­tines to minimize the risk of data loss upon specified types of errors. Upon timeouts, queuing is suspended and all information sectors pending in the queue are written out to the corresponding disk sectors. Upon specified types of write errors, queuing is discontinued and repeat­ed attempts are made to write out all information sectors to the corresponding disk sectors. For each unsuccessful attempt, the corresponding information sector is saved in the queue; the user is alerted, and subsequent read or write requests directed to the corresponding disk sector is serviced from the saved information sector in the queue.

Abstract: An operation circuit for M-bit parallel full addition includes partitioned adders (11 - 21) and first and second multiplexers. Each of the first multiplexers (22 - 25) selects one of paired provisional carry signals C ns-1 (1) and C ns-1 (0) supplied from the s-th partitioned adder, depending on the value of the real carry signal C (s-1)n-1  supplied from the (s-1)th partitioned adder, the selected one of the provisional carry signals being the real carry signal C ns-1  to be propagated from the s-th partitioned adder. Each of the second multiplexers (26 - 31) generates a pair of provisional carry signals Ck*(1) and Ck*(0) (k = n(S + 1) - 1, n(s + 2) - 1, ..., n(s + ℓ) - 1) by referring to provisional carry signals Cr(1) (or Cr*(10; r = k - n = ns - 1) and Cr(0) (or Cr*(0); r = k - n = ns - 1) which are lower by n digits than the ones to be generated. Then the second multiplexers generate ℓ real carry signals Ck at the same time by selecting either provisional carry signal Ck*(1) or Ck*(0), depending on the real carry signal C (s-1)n-1  relating to a digit which is one digit lower than the lowest-order digit of the s-th partitioned adder.

Abstract: Additive elements are added to Fe-N soft magnetic thin films along with oxygen, so that the thermal stability is remarkably improved. After annealing treatment at approximately 550°C, it is possible to provide an Fe-N soft magnetic thin film with a low coercive force. Similarly, it is also possible to provide a soft magnetic thin film having a low coercive force by introducing a combination of specific types of additive elements to Fe-N soft magnetic thin films. When oxygen is further added to the film, it is also possible to provide a soft magnetic thin film which has very excellent soft magnetic characteristics and good thermal stability. The soft magnetic thin films of the invention have good soft magnetic characteristics, a high saturation magnetic flux density and good thermal stability. A magnetic head of a metal-in-gap type using the soft magnetic thin film is also described.

Abstract: Format Conversion is performed between bit streams which embed sub-rate circuit data according to different protocols. The system (1) locates and extracts the sub-­rate circuit data embedded, in an input serial bit stream, in accordance with a first predefined protocol, (2) aligns the data in a buffer, and (3) creates an output bit stream in which the extracted circuit data is reformatted and inserted in accordance with a second predefined protocol. A programmable bit map driven format conversion module operates the data aligned in the aforementioned buffer. The conversion process is bidirectional and illustratively facilitates conversion between a single stage time division multiplexed data format and a two stage time division multiplexed format (e.g. X.50 and I.463), or, more generally, between any two predefined protocols. The system permits great flexibility in network system configuration and permits multiple channels of different format or frame alignments to be converted simultaneously.

Abstract: The improved annular sea (10) of the present invention provides a seal across an annular space between facing cylindrical surfaces (20, 24) and includes an outer annular ring (26), and an inner annular ring (28). The gap between the outer annular ring(26) and the inner annular ring (28) is suitably sealed at (27, 29) at one-end thereof so that the open end is open to admit pressure which is to be sealed between the two rings. An outer sealing element (36) is provided on the exterior of the outer annular ring, and an inner sealing element (38) on the interior of said inner annular ring so that pressure exerted between the annular rings urges them apart and their sealing elements against the surfaces of the annular space. In another form of the invention three annular rings are provided with one end of the inner and outer rings being sealing to the end of the intermediate ring and with sealing elements on the exterior of the outer ring and on the interior of the inner ring so that the sealing elements are urged into sealing engagement with the surfaces of the annular space. Another form of the invention includes annular rings which vary in thickness from one end to the other so that they may have greater or less flexibility as needed to provide a response to the pressure responsive movements of the inner and outer members.

Abstract: Plural images and plural register marks are printed on a photosensitive material with an original plate including an original image and register marks. Two kinds of masks are prepared before the printing: a photocomposing mask for masking the original image and the register marks on the original plate, and an exposing-out mask for masking the images and the register marks on the photosensitive material. First, the plural images and the register marks are printed on the photosensitive material while overlaying the original plate with the photocomposing mask by a photocomposer. Secondly, the photosensitive material is exposed with the exposing-out mask overlaid. Even if the plural images are nested to each other, the total procedure can be performed easily while using the two masks. The two masks can be fabricated easily on the basis of the shape of the original image and of the positions and orientations of the plural images on the photosensitive material.

Abstract: A multiple section photomultiplier tube (10) constructed as a matrix of several independent tubes (14) in one envelope (12). The photocathode (28) to dynode (31-38) spacings are isolated by a separator configuration (20) built with walls which interlock in cooperating slots, and each photocathode operates with its own independent dynode cage (26). The separation configuration (20) are buit-up of a shield structure which is composed of sheets and constitute an array of single chambers. One dynode (35) in each cage (26) is maintained electrically independent, and its connection is brought out of the envelope independently. This permits independent adjustment of the gain for each of the tube's multiple sections (14), so they can be adjusted to the same response for a standard radiation signal in an area. The entire tube can then be used to monitor a large area for radiation, and will yield the same response over its entire cathode area.

Abstract: This engined system cuts pipes (A) using the pressure of the centrifugal force on a blade (F) which rotating cuts into the pipe (A) until it is completely detached: such system reduces considerably the dimensions of the cutting device. 
     As an indicative but not restrictive example let's consider the case of counterweights (I,H) of about gr.250 each which can rotate at a speed of about 3000 revolutions per minute powered by an electric motor of only 500 watts. 
     In these conditions an half-inch zinc-coated steel pipe can be cut in 5/7 seconds. 
     The reduction through-put time and in the consuption of energy is self-evident.
