Abstract: A syndiotactic graft copolymer is here disclosed in which a radical polymerizable unsaturated compound is grafted on a propylene homopolymer or copolymer, and this graft copolymer is obtained by heating a homopolymer having a substantially syndiotactic structure of propylene or a copolymer having a substantially syndiotactic structure of propylene and another α-olefin and a radical polymerizable unsaturated compound such as an unsaturated carboxylic acid or an unsaturated silane in the presence of a radical initiator up to the decomposition temperature or more of the radical initiator. This kind of graft copolymer can be used as a composition for adhesion. The graft copolymer in which the radical polymerizable unsaturated compound is a hydrolyzable unsaturated silane can be converted into a crosslinked polymer by heating in the presence of water, and it can also be converted into a water-crosslinkable resin composition by adding various additive thereto.

Abstract: Cryptographic apparatus, and a related method for its operation, for in-line encryption and decryption of data packets transmitted in a communication network. A full-duplex cryptographic processor is positioned between two in-line processing entities of a network architecture. For example, in a fiber distributed data interface (FDDI) network, the processor is positioned between a media access control (MAC)(10) sublayer and a ring memory controller (RMC)(12). Incoming information packets are analyzed to decide whether or not they contain encrypted data and, if they do, are subject to decryption before forwarding. Outbound information packets have their data portions encrypted if called for, and are usually forwarded toward the network communication medium. Cryptographic processing in both directions is performed in real time as each packet is streamed through the processor. The processing of outbound information packets includes using optional data paths for looping of the processed information back in a reverse direction, to permit the host system to perform local encryption or decryption for various purposes.

Abstract: Apparatus and method are provided for vacuum-assisted, countergravity casting a melt (12) into a gas permeable mold (16,18) having an upstanding fill sprue (24) that supplies melt to a mold cavity (22) via a lateral ingate. Subambient pressure is applied to the mold fill sprue (24) and to the mold cavity (22) when a lower open end of the sprue and an underlying source of the melt are communicated to urge the melt upwardly to fill the sprue and the mold cavity (22). Thereafter, the pressure applied to the mold sprue is selectively raised relative to the subambient pressure applied to the mold cavity to cause the melt (12) in the sprue to drain therefrom without siphoning the melt from the melt-filled mold cavity. Pressurized gas can be introduced into the mold sprue as the mold is communicated to the melt source to blow floating slag and other debris away from the region of communication between the sprue lower open end and the source to reduce entry of slag into the mold cavity.

Abstract: A digital pulse processing device is capable of selecting precision. The digital pulse processing device includes a counter group for counting pulses output from a pulse output device, the counter group having a plurality of counters 110 and 111 that can be separated from and coupled with each other, a mode control circuit 129 for instructing separation and coupling of the counters 110 and 111, and a control circuit 116 for separating and coupling the counters 110 and 111 in accordance with the instruction of the mode control circuit 129. An overflow condition of the timer 119 is detected using an overflow flag. Detection of an overflow is conducted by setting the flag when an overflow condition has occurred twice or more. The flag is reset by rewriting the state of the flag by a software. An overflow condition which has occurred for the first time is detected in the conventional manner and is treated as carry or borrow. A register 128 is provided to hold the value of the timer 119 when a microcomputer reads in the counter 111. In this way, even when ΔA(i) = 0, speed detection operation can be executed using the value of the counter 111 obtained synchronously with the counting of the counter 110.

Abstract: To directly overwrite data on a magnito-optical recording medium formed of two exchange-coupled magnetic layers of a memory layer with a high coercive force and a low Curie point and a reference layer with a low coercive force and a high Curie point, an initializing magnetic field (e.g. 1000 to 5000 Oe) is applied to the medium to arrange the magnetization direction of only the reference layer; a recording magnetic field (e.g. 100 to 400 Oe) is applied and simultaneously a recording laser beam modulated according to data is irradiated upon the medium to record the data as magnetization directions of the memory layer; the initializing magnetic field is applied again to the medium to arrange the magnetization direction of only the reference layer; and a reproducing magnetic field (e.g. 1000 Oe or less) is applied and simultaneously a reproducing laser beam is irradiated upon the medium to reproduce the data. Since the reproducing magnetic field the same in direction as the recording magnetic field is applied to the medium in reproducing operation, recorded data can be stably reproduced without destruction by use of a high sensitive recording medium, in particular.
